This application is based on Japanese Patent Application (No. 2018-204153) filed on Oct. 30, 2018 and Japanese Patent Application (No. 2018-197480) filed on Oct. 19, 2018, the contents of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a connector.

2. Description of the Related Art

A connector including a terminal connected to an electric wire and a housing having a terminal accommodating portion that accommodates the terminal connected to the electric wire is widely known in the related art (see, for example, JP-A-H04-95369). In this type of connector, the terminal is generally crimped and fixed to the electric wire, and the terminal connected to the electric wire is accommodated in a regular insertion position of the terminal accommodating portion by inserting the terminal into the terminal accommodating portion from a rear end of the housing while holding the electric wire to which the terminal is fixed.

In recent years, with a demand for miniaturization of the connector, the terminal has been miniaturized, and a diameter of the electric wire has also been reduced. In a case where the electric wire is thin, when the terminal is inserted from the rear end of the housing by holding the electric wire to which the terminal is fixed, buckling is easy to occur in the electric wire. When buckling occurs in the electric wire, it is difficult to insert the terminal to the regular insertion position of the terminal accommodating portion.

SUMMARY OF THE INVENTION

The present invention has been made in view of the above circumstances, and an object thereof is to provide a connector capable of inserting a terminal into a regular insertion position of a terminal accommodating portion of a housing even when an electric wire connected to the terminal is thin.

In order to achieve the above object, the connector according to the present invention is characterized by the following (1) to (3).

a terminal configured to be connected to a wire and extend in a front-rear direction;

a housing which has a plate-like shape and has a terminal accommodating portion configured to accommodate the terminal, the housing having a ceiling wall portion that blocks an upper of a front portion of the terminal accommodating portion and an opening portion which is opened at an upper of a rear portion of the terminal accommodating portion; and

a flat plate-like cover configured to cover the opening portion of the rear portion of the terminal accommodating portion when the cover is assembled to the housing,

in which a protruding portion is provided on a lower surface of a front end portion of the cover and the protruding portion protrudes downward; and

in which the protruding portion presses a part of the terminal located in a primary locking position forward in the front-rear direction to move the terminal from the primary locking position to a regular insertion position when the cover is assembled to the housing.

(2) The connector according to the above (1), in which the cover is configured to be assembled to the housing by moving the cover forward with respect to the housing while the terminal is moved forward by pressing the protruding portion until a front end edge of the cover enters under a rear end edge of the ceiling wall portion while maintaining a state in which a rear part of the cover is inclined upward from a front part in a direction away from the housing, and then bringing the rear part of the cover near to the housing.
(3) The connector according to the above (1) or (2), in which the cover is configured to be assembled to the housing in a state where the front part of the cover is inclined upward from the rear part in a direction away from the housing while the protruding portion interferes with the terminal when the terminal is located in the primary locking position.

According to the connector having the configuration of the above (1), since the upper part (opening portion) of the rear portion of the terminal accommodating portion of the housing is opened, the terminal can be easily inserted to the primary locking position in the vicinity of the regular insertion position in the terminal accommodating portion while holding the terminal. In this state, the cover is assembled to the housing. In the assembly process, when the cover is moved to the front direction (forward) with respect to the housing, the terminal in the primary locking position is pressed forward by the protruding portion provided on the cover, so that the terminal can be moved to the regular insertion position.

As described above, even when the electric wire connected to the terminal is thin, the terminal can be certainty inserted to the regular insertion position. Further, even when the cover is assembled to the housing in a state where the terminal is in the primary locking position, the cover is detached from the housing, and the cover is assembled to the housing again while pressing the terminal forward by the protruding portion of the cover, so that it is possible to certainly insert the terminal in the primary locking position to the regular insertion position.

According to the connector having the configuration of the above (2), a shape of each component is designed such that the terminal reaches the (approximately) regular insertion position in a stage where the front end edge of the cover moving forward with respect to the housing enters under the rear end edge of the ceiling wall portion of the housing. Accordingly, after the terminal is inserted to the (approximately) regular insertion position by the protruding portion of the cover in the inclined state, the cover can be assembled to the housing by rotating the cover using the tip end side of the cover as a fulcrum. In addition, the terminal can reach the regular insertion position.

According to the connector having the configuration of the above (3), the cover is assembled to the housing in a state where the front part of the cover is inclined from the rear part in a direction away from the housing when the terminal is in the primary locking position. Therefore, a floating amount (floating height in the vertical direction) from the housing on the front part of the cover can be increased as compared with an aspect in which the cover is not inclined to the housing. Therefore, when it is detected that the cover is not assembled properly or the terminal is inserted halfway, the detection accuracy can be improved by measuring the floating amount using a checker fixture or the like. Furthermore, even though the terminal and the housing are miniaturized with a demand for miniaturization of the connector, it becomes possible to certainly detect the halfway insertion of the terminal.

According to the present invention, even when the electric wire connected to the terminal is thin, it is possible to provide a connector capable of inserting the terminal to a regular insertion position of the terminal accommodating portion of the housing.

The present invention has been described briefly. Further, details of the present invention will be clarified by reading a mode for carrying out the invention (hereinafter, referred to as “embodiment”.) described below with reference to the attached drawings.

DESCRIPTION OF EMBODIMENTS

Embodiment

Hereinafter, a connector1according to an embodiment of the present invention will be described with reference to the drawings. Hereinafter, for convenience of description, in an axial direction (fitting direction) of the connector1(which is same as a front-rear direction of a terminal), a side (left side inFIG. 1) to which a mating side terminal (not shown) is fitted is referred to as a front side, and an opposite side (right side inFIG. 1) is referred to as a rear side. An upper side and a lower side inFIG. 1are referred to as an upper side or an upper and a lower side or lower, respectively.

As shown inFIG. 2, the connector1includes a terminal10, a housing20, and a cover30. Hereinafter, each component constituting the connector1is described in order.

First, the terminal10is described with reference toFIG. 3toFIG. 5. In this example, a terminal10A shown inFIG. 3and a terminal10B shown inFIG. 4are used as the terminal10. Both of the terminals10A and10B are a female terminal formed by applying press processing, bending, or the like to a plate-like metal member, which includes a connecting portion11to which the mating side terminal (male terminal, not shown) is fitted, a conductor fixing portion12which fixes a conductor core wire of an electric wire W to the rear side of the connecting portion11, and a coating fixing portion13which fixes a coating of the electric wire W to the rear side of the conductor fixing portion12.

The connecting portions11of the terminals10A and10B have a square tubular shape, and a pair of protruding portions14protruding upward are formed at both end portions in a front-rear direction of a side in a width direction of an upper surface of the connecting portion11. As will be described later, the protruding portion14particularly on a front side of the pair of protruding portions14engages with a lance26(seeFIG. 8) of the housing20, and fulfills a retaining function of the terminals10A and10B.

As shown inFIG. 3, a pair of crimping blades15is formed on the conductor fixing portion12of the terminal10A. The conductor core wire of the electric wire W is crimped on the crimping blades15, so that the conductor core wire is fixed and electrically connected to the conductor fixing portion12. On the other hand, as shown inFIG. 4, a pair of caulking pieces15is formed on the conductor fixing portion12of the terminal10B. By crimping the conductor core wire of the electric by the caulking pieces15, the conductor core wire is fixed and electrically connected to the conductor fixing portion12. A pair of caulking pieces16are formed on the coating fixing portions13of the terminals10A and10B. By crimping a coating of the electric wire W by the caulking pieces16, the electric wire W is fixed to the coating fixing portion13.

The terminal10B is formed by applying press processing, bending, or the like to the plate-like metal member shown inFIG. 5. The connecting portion11is schematically shown. As can be understood fromFIG. 5, a plurality of through holes17penetrating in a plate thickness direction are formed on the conductor fixing portion12of the terminal10B. By providing the through holes17as described above, when the conductor core wire is crimped to the conductor fixing portion12, the conductor core wire can enter the through hole17and adhere closely to an inner wall surface of the through hole17with pressure during crimping. As a result, the conductor core wire can be firmly fixed to the conductor fixing portion12. Further, since a contact area between the conductor core wire and the conductor fixing portion12is increased, contact resistance therebetween is reduced.

Next, the housing20is described with reference toFIG. 6toFIG. 12. In particular, as shown inFIG. 6andFIG. 9, the housing20includes a housing body21having a rectangular flat plate shape. In each of upper and lower surfaces of the housing body21, a plurality of terminal accommodating portions for accommodating the plurality of terminals10are formed. Since configurations of the upper surface side and the lower surface side of the housing body21are somewhat different but are substantially the same, only the configuration of the upper surface side of the housing body21will be described below.

A plurality of standing walls22extending in the front-rear direction are integrally formed on the upper surface of the housing body21at intervals in the width direction. Each standing wall22fulfills a function of partitioning two terminal accommodating portions adjacent in the width direction. That is, a plurality of terminal accommodating portions partitioned by the plurality of standing walls22are formed on the upper surface of the housing body21so as to be arranged in the width direction.

A ceiling wall portion23is integrally formed on a front portion of the housing body21so as to block an upper part (opening portion) of the terminal accommodating portion. That is, the front portion of the terminal accommodating portion has a cylindrical shape whose upper part (opening portion) is blocked by the ceiling wall portion23, and an upper part of a rear portion of the terminal accommodating portion is opened. An opening24is formed at a front side end of each terminal accommodating portion (seeFIG. 6toFIG. 8). The mating side terminal (male terminal) is inserted into the terminal accommodating portion of the housing body21via the opening24.

As shown inFIG. 8, a tapered surface25inclined rearward and downward is formed at a rear end edge of the ceiling wall portion23. As will be described later, the tapered surface25is used when an upper cover30A is assembled to the housing20(seeFIG. 21). The lance26protruding downward toward the inside of each terminal accommodating portion is integrally formed on a lower surface of a central portion in a front-rear direction of the ceiling wall portion23.

As described above, the upper part of the rear portion of each terminal accommodating portion is opened in the housing body21. Therefore, as shown inFIG. 9andFIG. 10, the terminal10can be easily inserted into a primary locking position (halfway insertion position) in the vicinity of a regular insertion position in the front portion (tubular portion) of the terminal accommodating portion by placing the terminal10on the rear portion of the terminal accommodating portion and pushing the front side in while holding the terminal10(seeFIG. 11andFIG. 12).

In a process in which the terminal10is inserted to the primary locking position shown inFIG. 11andFIG. 12, the lance26rides on the protruding portion14along with elastic deformation by abutting against the protruding portion14on the front side of the terminal10, and then the lance26elastically returns to an initial position as the protruding portion14passes by. As a result, as shown inFIG. 12, the protruding portion14engages with the lance26, so that a function of retaining the terminal10from the housing20is exhibited.

Next, the cover30will be described with reference toFIG. 13toFIG. 22. In this example, the upper cover30A and a lower cover30B are used as the cover30(seeFIG. 2). The upper cover30A is assembled to the upper surface side of the housing body21to block the upper part of the rear portion of the terminal accommodating portion on the upper surface side, and the lower cover30B is assembled to the lower surface side of the housing body21to block the lower side of the rear portion of the terminal accommodating portion on the lower surface side.

First, the upper cover30A is described with reference toFIG. 13toFIG. 15.FIG. 13shows the upper cover30A when assembled to the housing body21, andFIG. 14shows the inverted upper cover30A.

The upper cover30A includes a flat plate-like cover body31. A plurality of standing walls32extending in the front-rear direction are integrally formed on the lower surface of the front portion of the cover body31at intervals in the width direction, which corresponds to the standing wall22of the housing body21. Accordingly, in the assembled state of the upper cover30A to the housing20, the upper part of the rear portion of the terminal accommodating portion of the housing body21is blocked by the upper cover30A, and the terminal accommodating portion having a tubular shape continuing in the front-rear direction is configured in the front portion and the rear portion of the terminal accommodating portion.

A tapered surface33inclined forward and upward is formed on a front end edge of the cover body31of the upper cover30A. As will be described later, the tapered surface33is used when the upper cover30A is assembled to the housing20(seeFIG. 21).

As shown inFIG. 15, a plurality of protruding portions34protruding downward are integrally formed at positions of the plurality of terminal accommodating portions (positions between adjacent standing walls32) in the width direction on the lower surface of the front end portion of the cover body31of the upper cover30A. As will be described later, when the upper cover30A is assembled to the housing20, the protruding portion34has a function of pressing the terminal10at the primary locking position forward to move the terminal10to the regular insertion position.

In the assembled state of the upper cover30A to the housing20, the rear portion of the cover body31of the upper cover30A protrudes from the rear end surface of the housing20to the rear side. The rear portion37of the cover body31functions as a so-called connector cover that accommodates and protects the plurality of electric wires W extending from the plurality of terminals10accommodated in the plurality of terminal accommodating portions to the rear side by cooperation with the rear portion37of the cover body31of the lower cover30B (seeFIG. 16andFIG. 17).

Engaging portions35which engage with engaging portions36of the lower cover30B when assembled to the housing20(seeFIG. 16andFIG. 17) respectively are integrally formed at a plurality of positions (four positions in this example) of both end portions in the width direction of the cover body31of the upper cover30A (seeFIG. 20).

Next, the lower cover30B will be described with reference toFIG. 16toFIG. 18.FIG. 16shows the lower cover30B when assembled to the housing body21, andFIG. 17shows the inverted lower cover30B. Configurations of the upper cover30A and the lower cover30B are somewhat different but substantially the same except that the upper cover30A and the lower cover30B are symmetrical in a vertical direction. Therefore, the lower cover30B is given the same reference numeral as the upper cover30A with respect to the configuration corresponding to each configuration of the upper cover30A to replace description thereof.

In the lower cover30B, as shown inFIG. 16andFIG. 17, a wire holding portion38is integrally formed on a further rear side (rear side end portion) of the rear portion37functioning as the connector cover. The wire holding portion38is a portion used to bundle and hold a plurality of electric wires W extending from the housing20to the rear side. The plurality of electric wires W extending from the housing20to the rear side are held by the wire holding portion38in the bundled state using a tie band or the like.

As shown inFIG. 19toFIG. 22, in a state where the upper cover30A and the lower cover30B are assembled to the housing20, and in a state where the tapered surface33at the front end edge of the upper cover30A enters a lower side of the tapered surface25at the rear end edge of the ceiling wall portion23on the upper surface side of the housing20, the front end edge of the upper cover30A and the rear end edge of the ceiling wall portion23on the upper surface side of the housing20are locked (seeFIG. 21). In a state where the tapered surface33at the front end edge of the upper cover30B enters an upper part of the tapered surface25at the rear end edge of the ceiling wall portion23on the lower surface side of the housing20, the front end edge of the lower cover30B and the rear end edge of the ceiling wall portion23on the lower surface side of the housing20are locked (seeFIG. 22). Further, the plurality of engaging portions35of the upper cover30A and the plurality of engaging portions36of the lower cover30B are locked to each other (seeFIG. 20). By these cooperation, each of the upper cover30A and the lower cover30B is assembled to be unmovable relatively to the housing20, and the upper cover30A and the lower cover30B are assembled to be unmovable relatively to each other.

Next, an assembly procedure of the connector1is described with reference toFIG. 23toFIG. 35. First, as shown inFIG. 23, each of the terminals10A is arranged in a rear portion where an upper part is opened in a predetermined terminal accommodating portion on the upper surface side (lower surface side in a regular direction) of the housing20in an inverted state by using a predetermined device, and a predetermined position of the terminal10A (typically, a rear end surface of the square tubular connecting portion11) is pushed forward to the primary locking position shown inFIG. 11andFIG. 12. Accordingly, the protruding portion14of the terminal10A is engaged with the lance26of the housing20, so that the terminal10A inserted into the terminal accommodating portion can be prevented from extracting from the housing20.

Next, as shown inFIG. 24, the electric wires W are connected to the terminals10A inserted into the terminal accommodating portions respectively by using the predetermined device. Specifically, the conductor core wire of the electric wire W is crimped to the pair of crimping blades15of the terminal10A, and coating of the electric wire W is crimped by the pair of caulking pieces16of the terminal10A.

Next, the housing20is inverted as shown inFIG. 25. Accordingly, a direction of the housing20is a regular direction. In this state, like the procedures shown inFIG. 23andFIG. 24, the terminals10A are respectively inserted into the predetermined terminal accommodating portions on the upper surface side of the housing20to the primary locking position, and the electric wires W are respectively connected to the inserted terminals10A as shown inFIG. 26andFIG. 27.

Next, as shown inFIG. 28, the terminals10B in a state in which the electric wires W are connected in advance are respectively inserted into the predetermined terminal accommodating portions on the upper surface side or the lower surface side of the housing20in which the terminals10A are not inserted yet to the primary locking position by using the predetermined device. This operation may be performed manually by an operator.

Next, the lower cover30B is assembled to the housing20as shown inFIG. 29, and then the upper cover30A is assembled to the housing20as shown inFIG. 30. Procedures of assembling the upper cover30A and the lower cover30B to the housing20are substantially the same except that the upper cover30A and the lower cover30B are symmetrical in a vertical direction. Therefore, only the procedure of assembling the upper cover30A to the housing20is described below with reference toFIG. 31toFIG. 35.

As shown inFIG. 31andFIG. 32, in a state in which the terminal10inserted into the terminal accommodating portion is at the primary locking position, first, as shown inFIG. 33, the front end edge of the upper cover30A (cover body31) approaches toward the rear end edge of the ceiling wall portion23of the housing20while maintaining a state in which the rear side of the upper cover30A is inclined upward compared with the front side, and as shown inFIG. 34, the protruding portion34of the upper cover30A is abutted against the rear end of the connecting portion11of the terminal10.

Next, the upper cover30A is moved forward in parallel to the housing20until the tapered surface33at the front end edge of the upper cover30A enters the lower side of the tapered surface25at the rear end edge of the ceiling wall portion23(until the front end edge of the upper cover30A is engaged with the rear end edge of the ceiling wall portion23) while maintaining the state (that is, a state in which the upper cover30A is inclined, and a state in which the protruding portion34abuts on the connecting portion11of the terminal10). At this time, due to the pressing of the protruding portion34, the terminal10moves from the primary locking position to the regular insertion position along with the forward movement of the upper cover30A.

Next, while maintaining a state in which the front end edge of the upper cover30A is engaged with the rear end edge of the ceiling wall portion23, the upper cover30A in the inclined state is rotated in a direction in which the rear side of the upper cover30A approaches the housing20using a tip end side of the upper cover30A as a fulcrum, as shown inFIG. 35. Accordingly, the plurality of engagement portions35of the upper cover30A and the plurality of engagement portions36of the lower cover30B are engaged with each other to obtain a state in which the upper cover30A and the lower cover30B are assembled to the housing20, as shown inFIG. 20described above. Finally, the plurality of electric wires W extending rearward from the housing20are held in the wire holding portion38in a bundled state using a tie band or the like. Thus, assembly of the connector1is completed.

As shown inFIG. 35, in a state where the upper cover30A is assembled to the housing20, the protruding portion34of the upper cover30A is in face-to-face contact with or adjoins the rear end face of the connecting portion11of the terminal10. Therefore, the function of retaining the terminal10from the housing20is exhibited. That is, in addition to the engagement of the protruding portion14of the terminal10with the lance26, a so-called double locking state is obtained by the engagement of the connection portion11of the terminal10with the protruding portion34.

As described above, the upper cover30A is designed to be assembled to the housing20in a regular state only by rotating the upper cover30A in the inclined state using the tip end side of the upper cover30A as a fulcrum. Even if the upper cover30A is parallelly moved from the upper side to the lower side to be assembled to the housing20in a state where the upper cover30A is maintained in parallel to the housing20, the upper cover30A cannot be assembled since the front end edge of the upper cover30A interferes with the rear end edge of the top ceiling wall portion23Interference with the edge prevents assembly.

As described above, according to the connector1according to the embodiment of the present invention, since the upper part of the rear portion of the terminal accommodating portion of the housing20is opened, the terminal10can be easily inserted to the primary locking position in the vicinity of the regular insertion position in the terminal accommodating portion while holding the terminal10. In this state, the cover30is assembled to the housing20. In the assembly process, when the cover30is moved to the front side with respect to the housing20, the terminal10in the primary locking position is pressed forward by the protruding portion34provided on the cover30, so that the terminal10can be moved to the regular insertion position.

As described above, even when the electric wire W connected to the terminal10is thin, the terminal10can be certainty inserted to the regular insertion position. Further, even when the cover30is assembled to the housing20in a state where the terminal10is in the primary locking position, the cover30is detached from the housing20, the cover30is assembled to the housing20again while pressing the terminal10forward by the protruding portion34of the cover30, so that it is possible to certainly insert the terminal10in the primary locking position to the regular insertion position.

Further, a shape of each component is designed such that the terminal10reaches the (approximately) regular insertion position in a stage where the front end edge of the cover30moving forward with respect to the housing20enters the lower side of the rear end edge of the ceiling wall portion23of the housing20. Accordingly, after the terminal10is inserted to the (approximately) regular insertion position by the protruding portion34of the cover30in the inclined state, the cover30can be assembled to the housing20by rotating the cover30using the tip end side of the cover30as a fulcrum. In addition, the terminal can reach the regular insertion position. The terminal10can reach the regular insertion position.

The present invention is not limited to the above embodiment, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiment, and can be appropriately modified, improved or the like. In addition, the material, shape, size, number, arrangement position, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

In the embodiment described above, as shown inFIG. 36andFIG. 37, the protruding portion34of the cover30interferes with the terminal10(more specifically, the connecting portion11) in a state in which the terminal10is in the primary locking position, so that a case where the cover30is assembled (may be assembled) to the housing20is assumed in a state in which the front side of the cover30is inclined from the rear side in a direction away from the housing20(specifically, the front end edge of the upper cover30A is not engaged with the rear end edge of the ceiling wall portion23, and the plurality of engagement portions35of the upper cover30A and the plurality of engagement portions36of the lower cover30B are locked to each other).

According to this, in the state where the terminal10is in the primary locking position, a floating amount H (floating height in the vertical direction, seeFIG. 37) from the housing on the front side of the cover30can be increased as compared with an aspect in which the cover30can be assembled in parallel to the housing20(not inclined). Therefore, when it is detected that the cover30is not assembled properly or the terminal10is inserted halfway, the detection accuracy can be improved by measuring the floating amount H using a checker fixture or the like. Furthermore, even though the terminal10and the housing20are miniaturized with a demand for miniaturization of the connector1, it becomes possible to certainly detect the halfway insertion of the terminal10.

Further, in the above embodiment, the rear portion37functioning as the connector cover and the wire holding portion38are integrally provided on a rear portion of the cover30assembled to the housing20. In contrast, as shown inFIG. 38, separately from the cover30, a connector cover40in which portions corresponding to the rear portion37and the wire holding portion38in the above embodiment are configured integrally may be provided.
