While first the unit case 2 of the present embodiment based on 1 and 2 is described, the unit housing 2 by forming (drawing) in only one axial direction (in the figure, in the Y-axis-up-down direction).
The flat part 20 of the unit housing 2 is with a pair of flat ribs (pair of protruding parts) three formed, which are arranged facing each other in parallel and out of the flat part 20 protrude. The pair of flat ribs three becomes at the time of molding the unit case 2 is formed integrally and is formed to have similar widths and thicknesses in the drawing direction (Y-axis upward direction).
The pair of flat ribs three has inner wall surfaces 3a formed by facing planar surfaces, outer wall surfaces 3b passing through backs of the inner wall surfaces 3a are formed, and lateral wall surfaces, which the inner wall surfaces 3a and the outer wall surfaces 3b connect and the flat part 20 cut vertically.
Here's the pair of flat ribs three formed such that the flat horizontal widths in the planar direction (Z-axis direction) between the front end portions 31 (free end part sides) and lower end parts 32 (fixed end-part sides) gradually increase, and formed so that the flat horizontal widths of the lower end portions 32 larger than the horizontal widths of the front end parts 31 become.
On the side wall surfaces 3c the flat ribs three are the side wall surfaces 3c1 the front end parts 31 the flat ribs three with bevelled parts 3c3 and with inclined surfaces 3c4 between the front end parts 31 and the lower end parts 32 formed at portions which abut against the pair of outer wall holding pieces 11 the later explained clamp 1 issue. That is, the side wall surfaces 3c the flat ribs three consist of the lateral wall surfaces 3c1 the front end parts 31 the flat ribs three , the lateral wall surfaces 3c2 the lower end parts 31 the flat ribs three , the beveled parts 3c3 and the inclined surfaces 3c4 ,
In the surroundings of the fixed end parts of the lower end parts 32 the pair of plane ribs three on the flat part 20 of the unit housing 2 are the front and back surfaces of the flat part 20 with recessed thin parts 21 . 22 educated. When an external force on the pair of flat ribs three is applied so that they approach each other, concentrates by forming the thin parts 21 . 22 in the vicinities of the attached end portions of the pair of plane ribs three on the flat part 20 due to the external force on the pair of plane ribs three occurring stress on the thin parts 21 . 22 and causes the thin parts 21 . 22 plastically deform, leaving the pair of plane ribs three approach each other de directions tends.
The thin parts 21 . 22 are also at the time of molding the unit case 2 in the same way as the flat ribs three integrally formed. On the front surface of the flat part 20 that forms the side, the pair of plane ribs three facing, are the recessed front thin surface parts 21 formed by pulling in the Y-axis upward direction, while on the rear surface facing the opposite side (side on which the pair of plane ribs three not facing each other) forms recessed rear thin surface portions 22 by pulling in the Y-axis downward direction.
In this way, the unitary housing 2 with the pair of flat ribs three of the present embodiment, by being formed only in an axial direction (Y-axis direction). In other words, the unitary case becomes 2 with the pair of flat ribs three is formed such that it has no portions that can be considered to be protruding when viewed from the Y-axis direction.
If next the clamp 1 of the present embodiment based on 1 and three is declared, is the pinch 1 with a rectangular shaped base end part 10 for fastening a retaining element 4a , which is part of a wiring harness 4 holds, trained. This base end part 10 is with a pair of flush outer wall mountings 11 formed facing each other and outwardly with a slope on the facing edges of the base end portion 10 expand.
In addition, the base end part 10 with a pair of inner wall holding pieces 12 formed from central positions of the other facing edges of the base end portion 10 towards the same sides as the outer wall support pieces 11 extend. Here are the direction of opposing the pair of outer wall holding pieces 11 (X-axis direction) and the direction of opposing the pair of inner wall holding pieces (FIG. 12 ) (Z-axis direction) are formed so as to intersect vertically.
Here, the clamp of the present embodiment is formed by drawing in the two axial directions of the Y-axis direction and the Z-axis direction. The base end part 10 is formed, with the draw holes 10a are required when the front end stop parts 121 of the pair of inner wall holding pieces 12 be formed, which will be explained later.
The pair of outer wall holding pieces 11 forms outer wall holding parts, which are the outer wall surfaces 3b the pair of plane ribs three on the facing inner wall surfaces 11a the outer wall holding pieces 11 hold when the clamp 1 and the pair of flat ribs three to be fastened (fixing stage). The inner wall surfaces 11a the pair of outer wall holding pieces 11 are formed in shapes extending from the base end portion 100 in a reverse V-shape to expand downward in the state in which they are inclined in each other in the direction of approach, with the outer wall surfaces 3b the pair of plane ribs three connect to.
Further, the pair of outer wall holding pieces 11 is formed so that the distance between the front end parts (sides opposite to the base end parts 10 ) wider than the distance of the facing pair of plane ribs three becomes. This serves to make the pair of plane ribs three in inclined directions, when the inner wall surfaces 11a be brought to the pair of outer wall holding pieces 11 to be facing, and the pair of plane ribs three against each other (adjacent stage).
The thickness side surfaces 11b the front end sides of the outer wall holding pieces 11 are with guides that lock in the Z-axis direction 13 provided, which the thickness side surfaces 11b the facing outer wall holding pieces 11 connect and against the plane ribs three abut to prevent the clamp 1 in the plane directions of the plane ribs three (Z-axis direction) releases.
The pair of inner wall holding pieces 12 forms inner wall holding parts, which are the inner wall surfaces 3a the pair of plane ribs three through lateral wall surfaces 121 the later explained front end support parts 121 in the inner wall holding parts 12 hold when the clamp 1 and the pair of flat ribs three be attached.
The pair of inner wall holding pieces 12 is with columnar parts 120 formed, extending vertically from the base end part 10 to the front end sides (end parts on the opposite side from the base end part 10 ), while the foremost end sides of the columnar parts 120 with front end support parts 121 are formed, which are located on the sides near the inner wall surfaces 11a of the pair of outer wall holding pieces 11 extend parallel in the X-axis direction. The shapes of the inner wall holding pieces 12 are inverted T-shapes when viewed from the Z-axis direction.
The front end parts of the front end holding parts 121 in the X-axis direction are with side wall surfaces 121 trained, the inner wall surfaces 11a the outer wall holding pieces 11 are facing. The lateral wall surfaces 121 are from the inner wall surfaces 11a the outer wall holding pieces 11 separated by distances corresponding to the thicknesses of the plane ribs three correspond, and are inclined to parallel to the inner wall surfaces 11a the outer wall holding pieces 11 to be. Notice here that the distances between the side wall surfaces 121 the front end holding parts 121 and the inner wall surfaces 11a the outer wall holding pieces 11 not exactly the same dimensions as the thicknesses of the flat ribs three include the normally allowed design error.
Further, the pair of front end support members 121 with protruding parts 121b formed, which protrude in the direction of the facing sides. The protruding parts 121b the pair of front end tethers 121 are formed in the shape curved (inclined surfaces). They are designed such that the facing portions of the front end support members 121 in the adjacent stage of the clamp 1 and the pair of plane ribs three to be brought seamlessly against the beveled parts 3c3 and the inclined surfaces 3c4 the lateral wall surfaces 3c the pair of plane ribs three to be abutted and made to deform elastically in separate directions.
Here is the distance between the protruding parts 121b the facing front end holding parts 121 shorter than the planar horizontal widths of the front end parts 3a the flat ribs three (Widths in the Z-axis direction), while the distance between the front end parts of the X-axis direction of the front end support members 121 longer than the distance between the front end parts 3a the pair of plane ribs three is trained.
The pair of inner wall holding pieces 12 is formed such that the protruding parts 121b of the pair of front end holding parts 121 against the chamfered parts 3c3 the front end parts 31 the pair of plane ribs three abut and thereby deform elastically in mutually separating directions and form the pair of elastic holding pieces.
The inner wall surfaces 11a the pair of outer wall holding parts 11 and the side wall surfaces 121 the front end holding parts 121 the pair of inner wall holding parts 12 Form gripping parts that are capable of the pair of plane ribs three in the state in which they tend in mutually approaching directions to grasp. The inner wall surfaces 11a the outer wall holding pieces 11 and the side wall surfaces 121 the front end holding parts 121 the inner wall holding pieces 12 are separated by the distance which corresponds to the thicknesses of the plane ribs three corresponds and inclines parallel to each other so that the gripping parts also incline with respect to the base end part 10 are formed.
Next, the fastening method for attaching the clamp 1 and a pair of flat ribs three with the above construction based on 4 to 6A to 6C described. Here is 4 a cross-sectional view along the line BB of a mounting structure of a terminal in a first adjacent stage to the terminal 1 and the flat rib three to let lie 5A is a cross-sectional view along the line AA in the second adjacent stage, 5B FIG. 4 is a cross-sectional view taken along line B - B in the second adjacent stage. FIG. 6A is a perspective view in a mounting stage, 6B is a cross-sectional view along the line AA in the mounting stage, and 6C is a cross-sectional view along the line BB of the terminal 1 in the attachment stage. Note that the cross-sectional view along the line AA is a cross-sectional view from the Z-axis direction of the cross section parallel to the Y-axis direction in the center of the X-axis direction of the attachment structure of a clamp in FIG 1 is considered while the cross-sectional view along the line BB is a cross-sectional view when the cross section parallel to the Y-axis direction in the center of the Z-axis direction of the attachment structure of a clamp in 1 from the X-axis direction.
First, the clamp 1 brought in a direction in which they are the flat part 20 from a vertical direction (Y-axis downward direction) approaches to move. In a first adjacent stage in which the clamp 1 and the pair of flat ribs three , as in 5A and 5B can be made to lie against each other, lie the outer wall surfaces 3b the front end parts 31 the pair of plane ribs three against the inner wall surfaces 11a the outer wall holding pieces 11 at. On the flat ribs three act due to the concern against the inner wall surfaces 11a the outer wall holding pieces 11 Forces in mutually approaching directions, causing the pair of plane ribs three to lean in mutually approaching directions.
Here the thin parts deform 21 . 22 , the front surface and rear surface, which in the surroundings of the attached end portions of the plane ribs three of the unit housing 2 are formed plastically, resulting in the flat ribs three which tend in mutually approaching directions to rotate around the attached end portions.
After the first adjacent stage, the flat ribs incline three , as in 6A shown, in the second adjacent stage, in which the clamp 1 is brought to a direction in which they are the flat part 20 approaching, moving farther, continuing in approaching directions, by striking against the inner wall surfaces 11a the outer wall holding pieces 11 issue.
Furthermore, the protruding parts are 121b the front end holding parts 121 the inner wall holding pieces 12 in the second adjacent stage, as in 6B shown against the beveled parts 3c3 and the inclined surfaces 3c4 attached to the side wall surfaces 3c the pair of plane ribs three are formed on, and the pair of inner wall holding parts 12 deforms elastically in separate directions. Here acts in the second adjacent stage, the force due to the inner wall retaining pieces 12 and the flat ribs three , which abut against each other, acts in the Z-axis direction.
Next, the flat ribs three in the attachment stage of attaching the pair of plane ribs three and the clamp 1 , as in 7A to 7C shown at the gripping parts of the outer wall holding pieces 11 and the inner wall holding pieces 12 gripped and attached to the clamp.
Declaring this mounting stage have plane ribs three , similar to the slope of the inner wall surfaces 11a the outer wall holding pieces 11 and the side wall surfaces 121 the front end holding parts 121 the inner wall-holding pieces (inclination of the gripping parts), an inclination in directions that approach each other by being against the inner wall surfaces 11a the outer wall holding pieces 11 issue.
Here are the inner wall surfaces 11a the outer wall holding pieces 11 and the side wall surfaces 121 the front end holding parts 121 separated by distances corresponding to the thicknesses of the plane ribs three correspond, then the fitting condition of the lateral wall surfaces 121 the front end holding parts 121 and the side wall surfaces 3c the flat ribs three raised, and the state before the elastic deformation is restored. That is, on the inner wall holding pieces 12 is no longer affected by the adjoining effect of the lateral wall surfaces 121 the front end holding parts 121 and the side wall surfaces 3c the flat ribs three acted upon, and they are restored to the state before the elastic deformation.
If the inner wall holding pieces 12 restored to the state before the elastic deformation, the side wall surfaces 121 the front end holding parts 121 the inner wall holding pieces 12 in the state where the outer wall surfaces 3b the flat ribs three in surface contact with the inner wall surfaces 11a the outer wall holding pieces 11 are in surface contact with the inner wall surfaces 3a the flat ribs three ,
Because of this, the pair of flat ribs three and the clamp 1 attached, with the pair of flat ribs three gripping parts are gripped from the inner wall surfaces 11a the outer wall holding pieces 11 and the side wall surfaces 121 the front end holding parts 121 the inner wall holding pieces 12 consist.
Even if in this fixed state, a force acts in a direction that the clamp 1 pulls out (Y-axis upward direction), a force acts on the inner wall surfaces 11a the outer wall holding pieces 11 in one to the pullout direction of the clamp 1 reverse direction (Y-axis downward direction), it can prevent the terminal 1 from the pair of flat ribs three is pulled out.
As explained above, in the present embodiment, it is possible to make the attachment structure of the clamp one that does not require separate metal members in which the clamp 1 not in the pair of flat ribs three lind that is inexpensive and has high security by making the structure a plastic clamp 1 and a pair of flat plastic ribs three attached.
Further, since it is possible to use the unit case 2 with the integrally formed pair of planar ribs three can be formed by pulling only in an axial direction, the increase in the number of steps in forming the unitary housing 2 be suppressed.
Further, in the attachment stage of the pair of plane ribs three and the clamp 1 due to the Z-axis locking guides 13 Even if the clamp is pulled in the Z-axis direction, the clamp can be prevented 1 from the pair of flat ribs three is pulled out.
Next, a second embodiment of the present invention will be based on 7A to 7C explained. Explanations of parts that are similar to the first embodiment will be omitted. Here is 7A FIG. 4 is a disassembled perspective view of a fixing structure of a clamp of the present embodiment; FIG. 7B is a front view of a clamp, and 7C is a Perspective view of a mounting stage of the clamp.
In the first embodiment, the columnar parts are 120 of the pair of inner wall holding pieces 12 formed so as to extend from the center positions of the edges of the base end portion 10 to the same sides as the outer wall holding pieces 11 extend. In the present embodiment, the columnar members are 120 of the pair of inner wall holding pieces 12 designed so that it, as in 7A to 7C shown extending from positions that are from center positions of the edges of the base end portion 10 in the direction of the sides of the inner wall parts 11a the outer wall holding pieces 11 to the same sides as the outer wall holding pieces 11 are shifted. That is, they are designed to be shifted in the X-axis direction so that they do not overlap when looking at the axes of the columnar parts 120 viewed from the Z-axis direction.
If the clamp 1 As a result, the forming by drawing in the two axial directions of the Y-axis downward direction and the Z-axis direction is possible, so that there is no longer any need for the draw holes 10a at the base end part 10 train. As a result, it is possible to change the size of the clamp 1 smaller than the clamp in the Z-axis direction 1 to make the first embodiment.
Further, in the first embodiment, the front end parts are on the outer wall holding pieces 11 with locking guides 13 formed, but in the present embodiment are blocking guides 13 formed by the columnar parts 120 and the outer wall support parts 11 on the side of the base end part 10 are connected near the columnar parts.
As a result, the length of the locking guides can 13 shortened in the X-axis direction compared to that of the first embodiment, so the terminal 1 of the present embodiment, reduce the consumption amount of the plastic material as compared with the clamp of the first embodiment.
Next, a third embodiment of the present invention will be based on 8th explained. Explanations of parts that are similar to the second embodiment will be omitted. 8th is a front view of a clamp.
In the present embodiment, the pair of inner wall holding pieces 12 In particular, the axes of the columnar parts are formed in L-shapes when viewed from the Z-axis direction 120 of the pair of inner wall holding pieces 12 formed offset in the X-axis direction, and the front end holding parts 121 are formed so that they only to the outer wall retaining pieces sides 11 near the columnar parts 120 extend. That is, the columnar parts 120 and the front end holding parts 121 are formed such that they do not overlap when viewed from the Z-axis direction.
If the clamp 1 Accordingly, it is possible to clamp 1 only by pulling in the Z-axis direction. Further, the clamp of the present embodiment can reduce the consumption amount of the plastic material as compared with the clamps of the first and second embodiments.
Next, a fourth embodiment based on 9 explained. Explanations of parts that are similar to the third embodiment will be omitted. 9 Fig. 10 is a disassembled perspective view of a fixing structure of a clamp of the present embodiment.
In the present embodiment, the pair of planar ribs three in the adjoining state, directly pinched by the fingers, etc., to apply a force in directions approaching each other to make it incline (first abutting state), and the inclined pair of plane ribs are brought toward the clamp 1 to abide (second adjoining stage).
For this reason, it is with the outer wall holding pieces 11 the clamp 1 no longer necessary, the inner wall surfaces of the present embodiment 11a the pair of outer wall holding pieces 11 to bring them to the adjacent stage of the clamp 1 (the first adjacent stage) against the front end parts 3a the pair of plane ribs three issue.
As a result, as in 9 shown the pair of outer wall holding pieces 11 , in the mounting stage of the clamp 1 the inner wall holding surfaces 11a that the plane ribs three Hold, omit, and can see the sections that are different from the base end part 10 and widen with an inclination, shorten. As a result, the clamp 1 of the present embodiment, reduce the consumption amount of the plastic material as compared with the terminals of the above embodiments.
Next, a fifth embodiment of the present invention will be based on 10A to 10C explained. Explanations of parts similar to the fourth embodiment will be omitted. 10A Fig. 10 is a disassembled perspective view of a fixing structure of a clamp of the present embodiment; 10B is a perspective view of an adjacent stage of a mounting structure of a terminal of the present embodiment, and 10C FIG. 15 is a perspective view of a fixing stage of a fixing structure of a clamp of the present embodiment. FIG.
In the present embodiment, the clamp is 1 , as in 10A to 10C shown with thin plate parts 110 on the outer wall holding pieces 11 configured to force the fingers through the fingers in directions approaching each other on the pair of planar ribs three apply. The thin plate parts 110 are formed so as to extend from the base end part 10 extend in an outwardly inclined direction, and are formed to be capable of elastically deforming in mutually approaching directions and in separating directions.
As a result, it is possible to use the fingers, etc., to pinch the thin parts in the adjacent state and the plane ribs three to make them lean in mutually approaching directions (see 10B ) and the clamp 1 and the pair of flat ribs three to rest against each other. There is no need to use the fingers, etc., around the flat ribs three as in the fourth embodiment, causing it to tilt; so it is possible to reduce the number of steps.
Note that the base end part 10 the clamp 1 in the present embodiment with draw holes 10a is formed, but these can be omitted as in the second and third embodiments.
Next, a sixth embodiment of the present invention will be based on 11 to 14A to 14C explained. Explanations of parts that are similar to the first embodiment will be omitted. Here is 11 FIG. 4 is a disassembled perspective view of a fixing structure of a clamp of the present embodiment; FIG. 12 FIG. 12 is a cross-sectional view of the housing when viewed from the Z-axis direction of a cross section of the planar ribs. FIG three in 11 parallel to the Y-axis direction in the middle of the X-axis direction, 13A is a front view of a clamp 1 , while 13B a side view of a clamp 1 is.
First, the pair of flat ribs three of the present embodiment based on 11 and 12 explains, with the front end parts 31 the flat ribs three are formed as flat shapes to obtain similar thicknesses in the pulling direction (Y-axis upward direction). The lower end parts 32 the flat ribs three are inclined so that the facing surfaces (inner wall surfaces 3a ) approach each other in the direction of the attached end-piece sides and with respect to the unitary housing 1 on the rear surfaces (outer wall surfaces 3b ) are vertical. Further, the flat horizontal widths of the front end parts 31 the flat ribs three (Z-axis direction widths) are formed to be smaller than the flat horizontal widths of the lower end parts 32 are.
Here is the back surface of the surface of the unit housing 2 where the insides of the flat ribs three are trained, as in 12 shown with recesses 220 formed so that the flat ribs three become hollow. The recesses 220 are formed by pulling in the Y-axis downward direction at the time of molding. Note that the unit housing 2 with the recesses 220 is formed such that there are no portions that can be considered as protruding when viewed in the Y-axis direction.
Because of these recesses 220 are the flat ribs three with thin parts 30 educated. In particular, the thin parts 30 formed such that the attached end portions of the lower end portions 32 the flat ribs three become thinner (lower thin parts 32a ), and are formed such that the boundaries of the lower end portions 32 and front end parts 31 the flat ribs three thin (upper thin parts 31a ).
The pair of flat ribs three The present embodiment has fixed end parts of the lower end parts 32 that with lower thin parts 32a are formed, therefore, when an external force in mutually separating directions on the lower end portions 32 applied, the focus due to the external force at the lower end portions 32 generated stresses on the lower thin parts 32a , and the lower end parts 32 plastically deform into divergent directions.
Furthermore, the pair has flat ribs three upper thin parts 31a at the borders of the front end parts 31 and the lower end parts 32 are formed, if therefore an external force in each other nourishing directions on the front end parts 3b applied, the focus due to the external force on the front end parts 31 generated stresses on the upper thin parts 31a , and the front end parts 31 plastically deform in directions approaching each other.
That is, the pair of plane ribs three The present embodiment is designed such that it is by the application of the external force on the lower end portions 32 in separate directions and the application of external force to the front end portions 31 bends in mutually approaching directions in a wide V-shape.
Next is the clamp 1 of the present embodiment based on 11 and 13A and 13B explained, with the clamp next to the base end part 10 , the pair of outer wall holding pieces 11 and the pair of inner wall holding pieces 12 an adjacent part 14 Has.
The pair of outer wall holding pieces 11 has holding parts 111 coming from the inner wall surfaces 11a at the base end pages 10 are formed, (fixed end parts sides) protrude. In the mounting stage of the clamp 1 hold the holding parts 111 the outer wall surfaces 3b the flat ribs three ,
The pair of inner wall holding pieces 12 is formed so as to be different from the base end part 10 to the sides of the outer wall holding pieces 11 widening. Further, the front ends of the pair of inner wall holding pieces 12 with holding parts 122 formed at sections that are the inner wall surfaces 11a the outer wall holding pieces 11 facing, to the sides of the outer wall brackets 11 project, and are with preceding parts 121b formed to the facing sides of the pair of inner wall holding pieces 12 protrude. The at the front ends of the pair of inner wall holding pieces 12 trained holding parts 122 keep the inner wall surfaces 3a the pair of plane ribs three in the attachment stage of the clamp 1 ,
Here is the pair of inner wall holding pieces 12 through a single support base 123 from the sides of the base end stop part 10 connected to the vicinity of the center in the Y-axis direction. Note that the flat horizontal widths of the front end sides of the inner wall support pieces 12 (X axis direction widths) longer than the distance between the front end parts 31 the pair of plane ribs three is formed while the flat horizontal width of the front end of the support base 123 shorter than the distance between the front end parts 31 the pair of plane ribs three and longer than the distance between the lower end parts 32 is trained.
In the present embodiment, the holding parts form 111 on the inner wall surfaces 11a the pair of outer wall holding pieces 11 are formed, and the holding parts 122 the front ends of the pair of inner wall holding pieces 12 Gripping parts that are capable of the pair of flat ribs three in the state in which it is inclined in mutually approaching directions to grasp.
The adjoining part 14 lies in the adjacent stage (first and second adjacent stage) against the inner wall surfaces 3a the lower end parts 32 the pair of plane ribs three and causes a force in separating directions on the lower end portions 32 the pair of plane ribs three acts. It is designed to be from the center position of the support base 123 the inner wall holding pieces 12 in the Y-axis downward direction to the sides of the outer wall holding pieces 11 in the same way as the inner wall holding pieces 12 widening.
Here is the flat horizontal width of the front end of the adjacent part 14 (X-axis direction width) shorter than the widths at the front end parts 31 the pair of plane ribs three formed, and the planar vertical width of the adjacent part (Y-axis direction width) is formed so that it is longer than the flat vertical widths of the inner wall holding pieces 12 becomes.
Next, a fixing method for fixing the clamp 1 and the flat ribs three with the above construction based on 14A to 14C explained. 14A is a front view of a mounting structure of a clamp in a first adjacent stage, 14B is a front view of a fastening structure of a clamp in a second adjacent stage, and 14C Fig. 10 is a front view of a fixing structure of a clamp in a mounting state.

In this embodiment, the flat horizontal widths of the front ends of the inner wall holding pieces 12 formed longer in the first adjacent stage than the width between the planar ribs three , the side wall surfaces 3c the flat ribs three in the state before bending into the wide V-shape (in the vertical direction with respect to the flat part 20 above state) and the protruding parts 121b of the pair of inner wall holding pieces 12 are made to reliably abut each other, and the inner wall support piece 12 Therefore, it can be made to elastically deform in directions separating from each other.
Next, a seventh embodiment of the present invention will be based on 15 and 16 explained. Explanations of parts that are similar to the second embodiment will be omitted. Here is 15 a disassembled perspective view of a mounting structure of a clamp of the present embodiment, while 16 is a front view of a mounting structure of a terminal in the mounting stage of the terminal.
In the present embodiment, the flat part 20 of the unit housing 2 , as in 16 shown with thin parts 21 . 22 formed so that the pair of planar ribs three plastically deformed to be separated. In particular, on the side where the pair of flat ribs three facing each other, by pulling in the Y-axis downward direction, rear thin surface parts 22 formed on the opposite side (the side where the pair of planar ribs are not facing each other) by pulling in the Y-axis upward direction front thin surface parts 21 be formed.

FIG.
To prevent the clamp 1 in the fastened state, in which the pair of plane ribs three is gripped by the gripping parts, in the plane direction of the plane ribs three (Z-axis direction) are in the first embodiment, the front end portions of the outer wall holding pieces 11 with locking guides 13 educated.
In this context, the pair is plane ribs three is formed such that it is capable of inclining in an approaching direction or a separating direction. When in the attached state, an external force from a direction parallel to the flat part 20 (X- and Z-axis directions) is applied, for this reason, the external force from the terminal 1 on the pair of flat ribs three act, and the pair of flat ribs three can detach from the gripping parts. Therefore, the present embodiment is constructed such that it allows to prevent the clamp 1 is pulled out of the pair of planar ribs when an external force is applied to the clamp 1 in a direction parallel to the surface direction of the flat part 20 (X- and Z-axis directions) is applied.
Below is the structure of the blocking structure of the terminal 1 based on 19 to 21 explained. As in 19 and 20 shown is the clamp 1 of the present embodiment is formed to have a rectangular outer Has shape when viewed from the vertical direction of the flat part (Y-axis direction). For this reason, the back surfaces of the inner wall surfaces 11a the outer wall holding pieces 11 the clamp 1 that is, the outer wall surfaces 11c are formed so as to become surfaces that are vertical to the base end part 10 are.
Further, positions that correspond to the four corners of the outer shape when they are from the vertical direction of the flat part 20 in a tight spot 1 (Y-axis direction), with recessed parts 113 formed, which form the blocking parts. In particular, the recessed parts 113 between the outer wall surfaces 11c and the thickness side surfaces 11b the outer wall holding pieces 11 educated.
The recessed parts 113 are formed so that they are in relation to the flat part 20 extend in vertical directions. Further, the recessed parts 113 with first recessed surfaces 113a parallel to the outer wall surfaces 11c the outer wall bracket 11 and second recessed surfaces 113b formed parallel to the thickness side directions.
On the other hand, the flat part 20 of the unit housing 2 with four locking protruding parts 23 formed in the vertical direction (Y-axis upward direction) of the flat part 20 protrude and are formed in square pillar shapes that correspond to the recessed parts 113 correspond. Note that four locking protruding parts 23 like the pair of flat ribs three , in the vertical direction of the flat part 20 protrude and thus at the time of forming the unitary housing 2 can be molded integrally.
The four locking protruding parts 23 are two each on the sides of the outer wall surface 3b the pair of plane ribs three are formed and formed in shapes that in the attached state, the pair of planar ribs three and the clamp 1 attached to the blocking parts, that is the recessed parts 113 , fit.
Here in the present embodiment, the locking protruding parts 23 formed in square pillar shapes corresponding to the first and second recessed surfaces 113a . 113b the recessed parts 113 the clamp 1 match, but the four locking protruding parts 23 For example, they may be formed into columnar shapes, etc., as long as the shapes are the recessed parts 113 the clamp 1 correspond.
Next, the structure becomes in the attachment stage of the clamp 1 of the present embodiment based on 21 explained. As in 21 shown, the four locking protruding parts fit 23 that from the flat part 20 protrude, and the recessed parts 113 the clamp 1 in the attachment stage of the clamp 1 together. In this condition is the clamp 1 in the structure at its four corners of the four locking protruding parts 23 surround.
Here are the blocking protruding parts 23 against the first and second recessed surfaces 113a . 113b the recessed parts 113 at. For this reason, an external force acting from any direction acts parallel to the flat part 20 on the clamp 1 is applied through the first and second recessed surfaces 113a . 113b the recessed parts 113 on the blocking protruding parts 23 ,
For example, if an external force from the X-axis direction is applied to the terminal 1 is applied, the external force acts through the second groove surfaces 113b on the square pillars 23 , Further, when an external force from the Z-axis direction is applied to the clamp 1 is applied, the external force acts through the first groove surface 113a on the square pillars 23 ,
In this way, when in the attached state, an external force from any direction parallel to the flat part 20 on the clamp 1 Applied, the external force can be applied by the clamp 1 on the pair of flat ribs three acts, be brought to, through the recessed parts 113 on the blocking protruding parts 23 to act. As a result, it is possible to fix the attachment structure of the clamp 1 and the pair of protruding parts three to make stronger, that is, it is possible, the pair of protruding parts three To make in the structure resistant to pulling out of the gripping parts.
Further, the external force acting on the pair of plane ribs three acts, be reduced; even if a strong external force on the clamp 1 Therefore, it is possible to break the pair of plane ribs three etc. to prevent. If the clamp 1 on the pair of flat ribs three is also possible, the clamp 1 through the locking protruding parts 23 to lead to a desired position, so that the mounting ability can be improved.
Here are the mating dimensions between the recessed parts on the clamp 1 and the locking protruding parts 23 (Dimensional tolerance) can be set to give a fit that allows tightening any time they connect.
Accordingly, the frictional force between the locking protruding parts decreases 23 and the recessed parts too; so it is possible to cope even with an external force from the Y-axis direction, and possible rattling between the clamp 1 and to suppress the gripping parts, so the attachment structure of the clamp 1 and the pair of plane ribs three be made stronger.
Note that the present embodiment is constructed such that the outer wall retaining pieces 11 on the two end sides of the clamp 1 are formed in the X-axis direction with recessed parts, but the invention is not limited thereto. Make positions on the two end sides of the clamp 1 in the X-axis direction, which is the outer shape of the clamp 1 form when the clamp 1 from the vertical direction with respect to the flat part 11 may be formed with outer wall parts that are in relation to the flat part 11 are vertical, and these outer wall parts may be formed with recessed parts.
Further, in the present embodiment, the explanation has been given of a structure in which positions corresponding to the four corners of the outer shape when viewed from the vertical direction of the flat part 20 in a tight spot 1 (Y-axis direction), with recessed parts 113 are formed, which form blocking parts, but the invention is not limited thereto.
That is, as the locking structure of the clamp 1 Any structure can be used, wherein if an external force from any direction parallel to the flat part 20 on the clamp 1 is applied, the external force coming from the clamp 1 on the pair of flat ribs three acts, is brought through the locking parts on the locking protruding parts 23 to act.
For example, a structure is also possible in which at least two facing sides of the four sides of the outer rectangular shape of the clamp 1 if they are from the vertical direction of the flat part 20 (Y-axis direction) are formed with recessed parts, and the flat part 20 with locking protruding parts 23 is formed, which are the recessed parts of the clamp 1 correspond.
Also by this construction, the external force coming from the clamp 1 on the pair of flat ribs three acts when an external force from any direction parallel to the flat part 20 on the clamp 1 is applied, by the recessed parts 113 on the blocking protruding parts 23 to act.
Next, the tenth embodiment of the present invention will be explained. Explanations of parts that are similar to the ninth embodiment will be omitted. The present embodiment differs in the blocking structure of the clamp 1 which was explained in the ninth embodiment.

In this way, the locking structure of the present embodiment is a structure in which holes corresponding to the outer shapes of the locking protruding parts 23 correspond, and the locking protruding parts 23 get connected. For this reason, an external force coming from one direction parallel to the outer flat part 20 (X- and Z-axis directions) is applied to the clamp, caused to pass through the holes which form the locking parts on the locking protruding parts 23 to act. As a result, it is possible to fix the attachment structure of the clamp 1 and the pair of protruding parts three to make stronger.
Here, the holes constituting the locking parts may be formed to have inner dimensions smaller than the outer dimensions of the flat part 20 trained locking protruding parts 23 are. That is, the dimensional tolerance between the holes forming the locking parts and the locking protruding parts 23 can be set such that a fit is obtained at all times, which provides a tightening margin, when the holes constituting the locking parts and the locking protruding parts 23 be connected to each other.
As a result, it is possible to have the locking protruding parts 23 in the holes forming the locking parts press, and possible, the mounting structure of the clamp 1 and the pair of plane ribs three to make stronger.
Note that the locking protruding parts 23 are constructed such that their outer circumferences match the inner peripheries of the holes forming the blocking parts. The External force applied to the clamp can be made to pass from a hole to a locking protruding part 23 to act. For this reason, it is sufficient to have at least one set of a locking projecting part 23 and a hole at the terminal respectively 1 and the flat part 20 train.
Further, when the locking parts are holes as in the present embodiment, it is also possible to have the locking parts passing through the holes on the flat part 20 be formed to form the locking protruding parts 23 at the terminal 1 be formed and trained at the terminal 1 trained locking protruding parts 23 to bring in the holes of the flat part 20 intervene. As a result, it is also possible, the mounting structure of the terminal 1 and the pair of protruding parts three make stronger, that is, the pair of protruding parts three resistant to pulling out of the gripping parts in the structure.
