A connector housing and a connector

Abstract: [Object] To mount a plurality of connector housings on a mating mounting member by one stay. [Solution] Connector housings 10 are connected by engaging first coupling portions 18 of one connector housing 10 with second coupling portions 28 of the other connector housing 10, and disengagement of the connector housings 10 is restricted by engaging a first locking portion 16 and a second locking portion 26. If an elastic locking piece 22 is elastically deformed to disengage the locking portions 16, 26 and disengage the coupling portions 18, 28, the connector housings 10 are disengaged from each other. The connector housing 10 is mounted on a stay S by inserting the stay S into an insertion space 23 and locking it by a stay locking portion 24. The connector housing 10 is disengaged from the stay S by elastically deforming the elastic locking piece 22 to disengage the stay locking portion 24 from the stay S.

Description: The present invention relates to a joint connector housing and to a joint connector provided with two or more such connector housings. In the case that a wiring harness is arranged in an engine compartment of an automotive vehicle, a specified arrangement path has been secured by fixing connector housings forming the wiring harness to a vehicle body. A means shown in FIG. 11 has been conventionally adopted to fix the connector housings to the vehicle body. This means is such that a plate-shaped stay 2 formed with a mount hole 3 is provided on a body 1, a projection 5 engageable with the mount hole 3 is formed on the bottom surface of a connector housing, guides 6 having a hook-shaped cross section are formed at the opposite sides of the projection 5, and the connector housing 4 is mounted on the stay 2 by sliding the hooked guides 6 while fitting them to the opposite side edges of the stay 2. With the means for mounting one connector housing 4 on the body 1 via one stay 2 as described above, not only the number of stays 2 increases, but also the body 1 is required to have a space for arranging a plurality of stays 2 in the case that a plurality of wiring harnesses are arranged in the engine compartment. For example, US-A-5 967 857 according to the preamble of claim 1 relates to a connector assembly comprising a plurality of housings stacked and combined together in a multi-stage manner, wherein each of the housings receives terminals each having a contact portion for connection to a mating terminal and a wire connection portion for connection to an end of a wire, and the housings, combined together, are adapted to be enganged with and fixed to a mounting portion of a vehicle body. It is an object of the present invention to enable a plurality of connector housings to be mounted on a mating mounting member by one stay while being compact in size and of minor complexity. This object is fulfilled by a connector housing according to claim 1 and by a connector according to claim 10. Preferred embodiments of the invention are subject of the dependent subclaims. This object is solved according to the invention by a joint connector housing according to claim 1 and by a joint connector according to claim 10. Preferred embodiments of the invention are subject of the dependent claims. According to the invention, there is provided a joint connector housing for a joint connetor connectable with a mating connector housing, having one or more terminal fittings accommodated therein wherein the joint connector housing is formed with: at least one first coupling portion, at least one second coupling portion for connecting the connector housing with the mating connector housing by being engaged with a corresponding first coupling portion of the mating connector housing and at least one first locking portion, the joint connector housing being mountable on a mating mounting member via a stay, wherein the connector housing is formed with : at least one elastic locking piece extending substantially along the outer surface of the joint connector housing while being spaced apart therefrom to define an insertion space for the stay and elastically deformable to incline toward and away from the joint connector housing, wherein a stay locking portion for preventing the stay from being withdrawn from the insertion space by engaging the stay is formed on an inner surface of the elastic locking piece facing or on the side of the insertion space, and a second locking portion for preventing the joint connector housing from being disengaged from the mating connector housing by engaging the first locking portion is formed on an outer surface of the elastic locking piece substantially opposite from the insertion space. The joint connector housings connected with each other are prevented from being disengaged from each other by engaging the first coupling portion of one connector housing with the second coupling portion of the other connector housing. The connector housing is mounted on the stay by inserting the stay into the insertion space to be engaged with the stay locking portion. According to a further preferred embodiment of the invention, an inserting direction of the stay into the insertion space is the substantially same as an extending direction of the elastic locking piece from its point of pivotal movement toward its extending end. With the stay inserted in the insertion space, the base end of the stay extends out of the insertion space toward the side opposite from the extending end of the elastic locking piece. Accordingly, a finger or a jig can be placed on the extending end of the elastic locking piece without any interference with the stay to disengage the stay locking portion of the elastic locking piece and the stay from each other. Preferably, a jig can be inserted in an insertion opening provided between the joint connector housing and the mating joint connector housing connected therewith and incline the elastic locking piece in a direction to bring the second locking portion away from the first locking portion. Thus, a jig can be inserted between the two joint connector housings connected with each other and incline the elastic locking piece in a direction to bring the second locking portion away from the first locking portion, and an insertion opening of the connector housing for the jig is preferably provided at a side opposite from a wire draw-out surface of the connector. Since the jig is or can be inserted from the side opposite from the one where the wires are drawn out, the wires do not interfere the insertion of the jig. Further preferably, a jig can be inserted between the two joint connector housings connected with each other and incline the elastic locking piece in a direction to bring the second locking portion away from the first locking portion, and an inserting direction of the jig into the joint connector housing is preferably substantially the same as an extending direction of the elastic locking piece from its point of pivotal movement toward its extending end. The jig is inclined to incline the elastic locking piece. Since a point of inclination of the jig and that of the elastic locking piece are located substantially at the same position at this time, the jig can be held substantially along the elastic locking piece. Still further preferably, an escape recess for permitting an inclining movement of the jig to incline the elastic locking piece is formed in the outer surface of the joint connector housing where the first locking portion is formed. By forming the escaping recess, a clearance between the outer surface where the first locking portion is formed and the outer surface where the elastic locking piece is formed can be narrowed. Further preferably, the escape recess is inclined with respect to an insertion direction of the jig into the insertion opening of the joint connector housing. Still further preferably, the first coupling portion comprises at least one first stopper portion which can come substantially into abutment with a corresponding second coupling portion of the mating joint connector housing. Most preferably, the second coupling portion comprises at least one second stopper portion which can come substantially into abutment with a corresponding first coupling portion of the mating joint connector housing, wherein first and second stopper portions preferably come into abutment with the corresponding second and first coupling portion, respectively substantially simultaneously. Accordingly, a loose movement of the joint connector housings, in particular in the mating direction, is restricted. According to the invention, there is further provided a joint connector comprising two or more joint connector housings according to the invention or an embodiment thereof being connectable with each other, wherein at least one of the joint connector housings is mountable to a mating mounting member by means of a stay. These and other objects, features and advantages of the present invention will become apparent upon reading of the following detailed description of preferred embodiments and accompanying drawings in which: FIG. 1 is a section showing a state where joint connector housings of a joint connector according to one preferred embodiment of the invention are connected and the connector is mounted on a stay, FIG. 2 is a section of the joint connector housing according to one preferred embodiment of the invention, FIG. 3 is a partial section showing a state before the joint connector housings are unlocked, FIG. 4 is a partial section showing an intermediate state while the joint connector housings are being unlocked, FIG. 5 is a partial section showing a state where the joint connector housings are unlocked, FIG. 6 is a partial section showing a state where an elastic locking piece and a stay are unlocked, FIG. 7 is a plan view of the joint connector housing, FIG. 8 is a bottom view of the joint connector housing, FIG. 9 is a front view of the joint connector housing, FIG. 10 is a rear view of the joint connector housing, and FIG. 11 is a section of a prior art means for mounting a joint connector on a stay. Hereinafter, one preferred embodiment of the invention is described with reference to FIGS. 1 to 10. A joint connector or joint connector housing according to this embodiment is mountable on a mating mounting member A via a stay S. The stay S is substantially plate-shaped and is horizontally secured while its leading end portion projects from an end of the upper surface of the mating mounting member A (see FIGS. 1 and 6). The stay S is substantially rectangular in plan view as a whole as shown by phantom line in FIG. 8, and is stepped or narrowed at the opposite side or lateral edges such that the leading end portion to be engaged with a connector housing 10 is narrower than the base end portion. The stepped or narrowed portions serve as contact portions Sa. A narrow portion Sb of the stay S is formed with a substantially rectangular locking hole Sc located in a widthwise center position. A connector is a so-called joint connector and is comprised of a connector housing 10, a plurality of harness-side terminal fittings 11 to be at least partly inserted into the connector housing 10 preferably from behind, and a joint terminal fitting 12 for electrically connecting the plurality of harness-side terminal fittings 11 inside the connector housing 10. Wires 13 connected with the harness-side terminal fittings 11 are drawn out backward preferably through the rear end surface, i.e. a wire draw-out surface or portion 14, of the connector housing 10. In the description below, right side in FIGS. 1 to 8 is referred to as front and vertical direction is based on FIGS. 1 to 6. The connector housing 10 is, as a whole, preferably in the form of a substantially flat rectangular parallelepiped whose width is larger than its height, and the front end thereof is or can be closed by a front wall 15. On a substantially flat upper or first surface 10U of the connector housing 10, a first locking portion 16 is formed preferably substantially in a middle position with respect to widthwise direction and forward and backward directions. The first locking portion 16 is in the form of a projection, and the front surface thereof is formed into a guide surface 16F which is inclined with respect to the upper surface 10U of the connector housing 10, i.e. to forward and backward directions (disengaging direction from a mating connector housing 10) while the rear surface thereof is formed into a locking surface 16R which extends upward from the upper surface 10U of the connector housing 10 at an angle different from 0° or 180°, preferably substantially at a right angle or in an overhanging manner. In the upper surface 10U of the connector housing 10, an escape recess 17 is formed in a position before the first locking portion 16. This escape recess 17 is narrow in forward and backward directions and inclined downward to the front. In other words, the escape recess 17 is deeper toward its front end. The left and right inner surfaces of the escape recess 17 are so inclined as to be wider toward the upper end when viewed from front or so that the escape recess 17 is at its upper end wider toward the front of the connector housing 10 while being substantially of equal width at its bottom end (FIG. 7). Accordingly, the escape recess 17 has substantially V-shape or bottomed V-shape when seen in cross-section. The bottom surface of the escape recess 17 has a substantially constant width over its entire length along forward and backward directions, and this width is substantially equal to that of the first locking portion 16. A pair of left and right or lateral first coupling portions 18 are formed at the opposite sides of the first locking portion 16 on the upper surface 10U of the connector housing 10. Each coupling portion 18 has, as can be seen in FIG. 9, substantially an L-shaped (hook-shaped) cross section bent inwardly when viewed from front, and substantially linearly extends in forward and backward directions (fitting directions of the connector housings 10). Further, a first stopper 19 is formed at the rear end of the first coupling portion 18. A substantially rectangular plate portion 20 is formed preferably substantially in a widthwise center position of a substantially flat lower or second surface 10L of the connector housing 10. The plate portion 20 is substantially continuous with the lower surface 10L of the connector housing 10 at its opposite side edges and is substantially parallel to the lower surface 10L of the connector housing 10. A pair of left and right or lateral slits 21 are formed preferably substantially in a widthwise middle portion of the plate portion 20, thereby forming an elastic locking piece 22 which cantilevers backward substantially in parallel with the lower surface 10L of the connector housing 10. This elastic locking piece 22 extends along the lower surface 10L of the connector housing 10 while being spaced apart therefrom to define an insertion space 23 for the stay S, and is elastically deflectable or deformable substantially in directions (vertical direction) toward and away from the lower surface 10L of the connector housing 10. On the inner surface (upper surface) of the elastic locking piece 22 substantially facing or corresponding to the insertion space 23, a stay locking portion 24 in the form of a projection is formed to prevent the stay S from being withdrawn from the insertion space 23 by locking the stay S. The front surface of the stay locking portion 24 is formed into a guide surface 24F which is inclined with respect to forward and backward directions (inserting direction of the stay S into the insertion space 23), and the rear surface thereof is formed into a locking surface 24R which extends preferably at a substantially right angle to or overhangs from the upper surface 10U of the connector housing 10. On the other hand, a second locking portion 26 in the form of a projection engageable with the first locking portion 16 is formed on the outer (lower surface) of the elastic locking piece 22 at the side opposite from the insertion space 23. The front surface of the second locking portion 26 is formed into a locking surface 26F which extends preferably at a right angle to or overhangs with respect to forward and backward directions (disengaging direction from the mating connector housing 10), and the rear surface thereof is formed into a guide surface 26R which is inclined with respect to forward and backward directions (fitting direction with the mating connector housing 10). Further, guide grooves 27F, 27R extending forward and backward from the second locking portion 26 are formed in the lower surface of the elastic locking piece 22. The opposite side edges of the plate portion 20 are rib-shaped second coupling portions 28 projecting outwardly with respect to widthwise direction and linearly extending preferably substantially in parallel in forward and backward directions. The second coupling portions 28 are slidably engageable with the grooves of the first coupling portions 18 of the mating connector housing 10 in forward and backward directions. Further, second stoppers 29 are formed at the front ends of the second coupling portions 28. Here, the directions of the respective members are collectively described. The extension of the elastic locking piece 22 is substantially the same as a direction in which the connector housing 10 formed with the elastic locking piece 22 is fitted to the mating (upper in FIG. 1) connector housing 10 by the locking portion 16. The extension of the elastic locking piece 22 is substantially the same as a direction in which the stay S is inserted into the insertion space 23. The extension of the elastic locking piece 22 is substantially the same as a direction in which a jig J is inserted into the connector housing 10. The inserting direction of the stay S into the insertion space 23 is substantially the same as the inserting direction of the jig J into the connector housing 10. A direction in which the wires 13 are drawn out from the connector housing 10 is substantially the same as the extension of the elastic locking piece 22. The drawing direction of the wires 13 from the connector housing 10 is substantially the same as the inserting direction of the stay S into the insertion space 23. The drawing direction of the wires 13 from the connector housing 10 is substantially the same as the inserting direction of the jig J into the connector housing 10. Next, the action of this embodiment is described. The first and second connector housings 10, 10' are connected with each other by engaging the second coupling portions 28 of the upper or first connector housing 10' with the first coupling portions 18 of the lower or second connector , housing 10 from front in FIG. 1. During this connecting operation, the first locking portions 16 of the lower connector housing 10 move in the front guide groove 27F of the upper connector housing 10'. Subsequently, when the guide surfaces 16F, 26R of the first and second locking portions 16, 26 come into contact with each other, the elastic locking piece 22 of the upper connector housing 10' is substantially elastically displaced upward (direction closer to the upper surface 10L of the upper connector housing 10' and toward the inside of the insertion space 23) by the inclination of the guide surfaces 16F, 26R, and the second locking portion 26 of this elastic locking piece 22 moves over the first locking portion 16 of the lower connector housing 10. When the connector housings 10, 10' are substantially properly connected, the elastic locking piece 22 is elastically restored substantially to its original position to engage the locking surface 26F of the second locking portion 26 with the locking surface 16R of the first locking portion 16. This prevents the upper connector housing 10' from being disengaged forward from the lower connector housing 10. Simultaneously, the rear ends of the second coupling portions 28 of the upper connector housing 10' come into abutment against the first stoppers 19 of the first coupling portions 18 of the lower connector housing 10, and the second stoppers 29 of the second coupling portions 28 come into abutment against the front ends of the first coupling portions 18. These two abutments restrict any further loose movement of the connector housings 10, 10' in the fitting direction (any further backward movement of the lower connector housing 10 with respect to the upper connector housing 10'). In this way, the connector housings 10, 10' are locked into each other while having their relative movements in forward and backward directions restricted. When the connector housings 10, 10' are to be disengaged from each other, the narrow jig J in the form of a flat or minus screwdriver is opposed to an insertion opening 30 defined between the connector housings 10, 10' as shown in FIG. 3, the jig J is or can be inserted between the elastic locking piece 22 and the upper surface 10U of the lower connector housing 10, i.e. into the escape recess 17 through the insertion opening 30 and the leading end thereof is inclined upward with respect to the inserting direction (toward the elastic locking piece 22). A point of inclination at this time is the front end (end toward the insertion opening 30) of the escape recess 17. When the jig J is inclined as above, the leading end of the jig J pushes or can push the elastic locking piece 22 in a position slightly before the first locking portion 16 to forcibly elastically displace the elastic locking piece 22 upward. As a result, the first locking portion 16 and the second locking portion 26 are or can be disengaged from each other to permit the connector housings 10, 10' to relatively move in their disengaging direction. The connector housings 10, 10' are disengaged by sliding the upper connector housing 10 forward as shown in FIG. 5 while keeping the first and second locking portions 16, 26 disengaged. When the connector housing 10 is to be mounted on the stay S, the lower surface 10L of the connector housing 10 is brought closer to the stay S horizontally projecting backward or projecting in a specified (predetermined or predeterminable) direction toward the connector housing 10 to at least partly fit the stay S into the insertion space 23. During this fitting operation, the leading end (rear end) of the stay S comes into contact with the guide surface 24F of the stay locking portion 24 to substantially elastically displace the elastic locking piece 22 downward (direction away from the lower surface 10L of the connector housing 10 and opposite from the insertion space 23) by the inclination of the guide surface 24F. When the connector housing 10 reaches its proper mount position on the stay S, the contact portions Sa of the stay S come into contact with the front end surfaces of the opposite ends of the plate portion 20 to restrict any further insertion of the stay S into the insertion space 23, and the elastic locking piece 22 is elastically restored substantially to its original position to engage the stay locking portion 24 with the locking hole Sc. The locking surface 24R of the stay locking portion 24 is engaged with the rear edge of the locking hole Sc from front, with the result that the connector housing 10 is prevented from being disengaged backward from the stay S. In this way, the connector housing 10 is locked into the stay S while making it impossible to withdraw or further insert the stay S from or into the connector housing 10. When the connector housing 10 is to be detached from the stay S, a finger or manipulating jig is or can be placed on the rear end (free end) of the elastic locking piece 22 to forcibly elastically displace the elastic locking piece 22 downward (direction away from the lower surface 10L of the connector housing 10). Then, as shown in FIG. 6, the stay locking portion 24 is disengaged from the locking hole Sc of the stay S. Thus, the connector housing 10 can be detached from the stay S by being moved backward while keeping the stay locking portion 24 and the locking hole Sc disengaged. As described above, in this embodiment, the upper surface 10U of the connector housing 10 is formed with the first locking portion 16 as the connecting means for the connector housings 10, whereas the lower surface 10L thereof is formed with the elastic locking piece 22 provided with the second locking portion 26 as the connecting means for the connector housings 10, 10' and the stay locking portion 24 as the mounting means for mounting the connector housing 10 on the stay S. Thus, a plurality of connector housings 10 can be mounted on one stay S while being connected with each other. Preferably, the two mating connector housings 10, 10' have identical or similar shape and/or configuration. Further, since the inserting direction of the stay S into the insertion space 23 is the same as the extending direction of the elastic locking piece 22 from its point of pivotal movement toward the extending end, the base end (front end) of the stay S extends out of the insertion space 23 in a direction opposite from the extending end (rear end) of the elastic locking piece 22 with the stay S inserted in the insertion space 23. Accordingly, a finger or the jig J can be placed on the extending end of the elastic locking piece 22 without any interference with the stay S to disengage the stay locking portion 24 of the elastic locking piece 22 and the stay S from each other. The insertion opening 30 of the connector housing 10 for the jig J is formed at the side preferably substantially opposite from the wire draw-out surface 14 of the connector housing 10, and the jig J is or can be inserted from the side substantially opposite from the one where the wires 13 are drawn out. Thus, the wires 13 do not interfere the insertion of the jig J. The jig J is inclined to incline the elastic locking piece 22. In this embodiment, since the inserting direction of the stay S into the connector housing 10 is substantially the same as the extending direction of the elastic locking piece 22 from its point of pivotal movement toward the extending end, a point of inclination of the jig J and that of the elastic locking piece 22 are located substantially at the same position with respect to the forward and backward directions. Therefore, the jig J can be held substantially along the elastic locking piece 22. Further, since the escape recess 17 for permitting the inclining movement of the jig J to incline the elastic locking piece 22 is formed in the upper surface 10U of the connector housing 10, a clearance between the upper surface 10U (where the first locking portion 16 is formed) of the lower connector housing 10 and the lower surface of the elastic locking piece 22 of the upper connector housing 10' can be narrowed with the upper and lower connector housings 10 connected with each other. The present invention is not limited to the above described and illustrated embodiment. For example, the following embodiments are also embraced by the technical scope of the present invention as defined in the claims. Beside the following embodiments, various changes can be made without departing the present invention as defined in the claims.
