Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding jig for a laterally extending connector, and more particularly, to the workability of inserting a terminal-attached electric wire inserted into a connector mounted vertically to a wiring plane of the electric wire. It is intended to improve.

[0002]

2. Description of the Related Art Generally, a wire harness W / H is shown in FIG.
As shown in (1), the electric wires are laid in a predetermined path by the electric wire holder 2 erected on the assembling work table 1 and the components such as the connector C1 are attached to a large number of branched terminals. Since the connector C1 is normally arranged in the same direction as the wiring plane of the electric wire, the terminal insertion surface C
The insertion direction of the terminal-equipped electric wire Wa into the terminal a is straight. For this reason, the operation of inserting the terminal-equipped electric wire Wa into the terminal insertion surface Ca can be naturally performed without any particular difficulty, and the terminal-equipped electric wire Wa introduced into the connector C1 is located at the position where the branch point A and the connector C1 are arranged. It is stretched to a predetermined dimension with high precision between the standing wire holder 2.

[0003] On the other hand, as shown in FIG.
There is a case where the terminal insertion surface Ca is arranged substantially vertically upward with respect to the wiring plane of the above. In this case, a holding jig 3 for holding the horizontal connector C2 in the above direction is used. And, when assembling the wire harness W / H,
At the time of wiring of the temporary bundling (a sub-assembly in which a part of the electric wire with the terminal is inserted in the connector in advance), the holding jig 3 holds the laterally extending connector C2 to be arranged in the above direction. Along with this, the bent portion 4 turned around 90 ° is formed near the upper part of the terminal insertion surface Ca in the terminal-equipped electric wire Wa inserted into the connector C2. In this state, another temporary binding terminal-equipped wire Wa to be wired is further inserted into the lateral connector C2 held by the holding jig 3.

[0004]

However, as described above, the horizontal connector C2, which is disposed with the terminal insertion surface Ca directed substantially vertically upward with respect to the wiring plane of the electric wire, is a large-sized connector having a large number of terminals. In the case of a multi-pole connector, the laterally extending connector C2 has a booster mechanism D using a lever for reducing a fitting force at the time of fitting with the mating connector C3 as shown in FIGS. May have been added. The booster mechanism D includes a lever Db having a guide groove Da into which a pin C3a provided in a mating connector C3 to be fitted is introduced.
The lever D is attached to the side wall of the housing Cd.
b, the operating end of which is slidable up and down on the outer periphery of the housing Cd via a slide cam mechanism Dc.
e. Then, by pushing down the holder Ce from the position where it is raised above the terminal insertion surface Ca, and pulling the pin C3a of the mating connector C3 through the guide groove Da, the fitting can be performed with a light operating force. It has become.

[0005] In the above case, when the wire harness W / H is completed, the horizontal connector C2 must be mounted in a posture ready for fitting with the mating connector C3 by sliding the holder Ce above the terminal insertion surface Ca. is there. In this fitting preparation posture, the holder Ce at the ascending position becomes an obstacle, and the operation of inserting the electric wire Wa with the terminal into the housing Cd during wiring is performed with respect to the terminal insertion surface Ca located at the back in the holder Ce. An insertion operation is required, which significantly reduces workability. Moreover, the holder Ce
Is locked by the engagement between the stoppers Cd1 projecting from the left and right ends of the housing Cd at the ascending position and the lock claws Ce1 projecting from the left and right inner surfaces of the holder Ce, so that the holder Ce is lowered. In some cases, I had to release that lock.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and when assembling a wire harness on an assembling work table, the lock between the housing and the holder can be achieved only by setting the horizontal connector to the holding jig. It is an object to improve the workability of inserting a terminal-attached electric wire by releasing the holder and lowering the holder to the terminal insertion surface at the same time as the release.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a housing of a laterally extending connector is housed in a holder, and stoppers on both right and left sides of the housing are provided with locking claws of the holder. And the terminal insertion surface of the housing is lower than the upper surface of the holder.
At the tip of the spindle that is erected on the wire harness assembly work table,
A horizontal board is connected, a pair of left and right connector holding portions are erected on the upper surface of the board, and the connector holding portion has a U-shaped vertical frame having an open facing surface, and inner surfaces on both sides of the vertical frame. When the left and right sides of the housing housed in the holder are inserted into the vertical frame, the lock between the stopper of the housing and the lock claw of the holder is released by the lock release bar. Then, the holder is lowered, and the terminal insertion surface of the housing is substantially at the same position as the upper end surface of the holder. We provide jigs.

According to the first aspect of the present invention, the stopper and the lock claw which have locked the holder at the raised position with respect to the housing can be easily locked by the lock release bar only by setting the laterally extending connector to the holding jig. Can be canceled. Therefore, the holder at the ascending position is displaced downward, so that the terminal insertion surface can be exposed at substantially the same position as the upper end surface of the holder. The terminal can be inserted.

On the outer surface of the connecting portion of the vertical frame of the connector holding portion, a holder hooking portion is protruded, and lock pieces for locking the electric connection box provided on the outer surfaces on both right and left sides of the holder are provided when the holder is lowered. It is preferable to be locked and held by the holder hook portion (claim 2). Accordingly, the holder displaced to the lowered position is locked and held by the holder hooking portion, so that the housing and the holder can be securely fixed on the substrate of the holding jig. Therefore, a stable state can be maintained without the holder being unexpectedly lifted during the operation of inserting the terminal into the terminal insertion surface, and the workability when inserting the terminal can be further improved.

The pair of left and right connector holding portions may be formed by cutting off a central portion of a mating connector to be fitted with the connector and leaving the left and right side portions (claim 3). By using the mating connector in this way, a holding jig can be easily and inexpensively manufactured while ensuring high-precision compatibility with the horizontal connector with a holder.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a required terminal processing unit in an assembling process of the wire harness W / H. In the terminal processing unit, the above-mentioned lateral connector C2 and the terminal insertion surface Ca are substantially perpendicular to the wiring plane of the electric wire. A process is performed for mounting the device in an upward state. For this reason, a holding jig 13 for holding the assembling worktable (not shown) sideways connector C2 in the above posture is provided.

The holding jig 13 connects a horizontal board 13b to the tip of a support shaft 13a erected on an assembling work table, and a pair of left and right connector holding sections 1 on the upper surface of the board 13b.
4A and 14B are erected facing each other. As shown in FIGS. 1 and 2, the connector holding portions 14A and 14B include a pair of right and left vertical frames 14a each having a U-shaped cross section with an open facing surface, and the interval between the end faces of the vertical frames 14a is horizontal. The interval is set such that the housing Cd of the output connector C2 is internally fitted in the longitudinal direction. A holder C is provided between the inner surfaces of the vertical frames 14a.
The width of the lock claw Ce1 of e is set so that it can be fitted inside (FIG. 6). Further, a pair of lock release bars 14b, which forcibly release the engagement of the stopper Cd1 of the housing Cd with the lock claws Ce1 of the holder Ce, are provided on the inner surfaces of the upper side portions of the vertical frame 14a.

The relationship between the lock claw Ce1 and the stopper Cd1 in the horizontal connector C2 will be described in more detail. As shown in FIG. 9, the lock claw Ce1 is attached to the holder Ce.
The stopper Cd1 is narrower than the lock claw Ce1 and has locking surfaces Cd2 on both sides of the housing Cd. It is composed of a projection integrally protruded on the side. When the holder Ce rises above the terminal insertion surface Ca of the housing Cd, the stopper C
Both are locked in a state where the center of the lower surface of the lock claw Ce1 is in contact with the locking surface Cd2 of d1.

As shown in FIGS. 2 and 6, a pair of unlock bars 14b projecting from the vertical frame 14a
a when the housing Cd is inserted into the stopper Cd1
Is set to an interval that can be sandwiched from both sides, and the thickness dimension is set to be larger than the protruding height of the stopper Cd1. Further, on the upper surface of each lock release bar 14b, a tapered guide surface 14c that becomes narrower upward is formed in order to sequentially open and displace the lock claws Ce1 of the holder Ce outward.

On the outer surface of the connecting portion 14d of the vertical frame 14a, there is provided a lock piece Ce for locking to an electric connection box provided on both left and right outer surfaces of the holder Ce of the horizontal connector C2.
The holder hooks 14e for locking and holding the hooks 2 are protrudingly provided. The lock piece Ce2 is a lock claw Ce.
As in the case of 1, an elastic plate-shaped member cantilevered from the upper portion as a base portion and integrally extended downward, a locking claw Ce4 protrudes inward in the horizontal direction at the lower end portion, and a lock at the upper end portion. Piece Ce
An operation part Ce3 for forcibly expanding the opening 2 is formed. Correspondingly, as shown in FIG. 2, the holder hooking portion 14e forms a guide surface 14f that is inclined upward and inward at the upper portion, and the holder Ce is completely attached to the vertical frame 14a at the lower portion. In the fitted state, the locking claw C
A locking step 14g is formed to lock e4. The board 13b has a lock claw Ce1 inserted into the vertical frame 14a.
An opening 14h for avoiding interference with the lock claw Ce1 is formed corresponding to the insertion position of the lock claw Ce1.

On the substrate 13b, a connector holding portion 1 is provided.
The wire holder 15 is erected in accordance with the direction in which the terminal-equipped wire Wa inserted into the lateral connector C2 held by 4A and 14B is pulled out. Receiving part 1 of the wire holder 15
The height position of 5a is set to the height at which the wires are held in the sideways state corresponding to the rising position of the holder Ce in the sideways connector C2 held by the connector holding parts 14A and 14B.

Next, the operation of the holding jig 13 will be described. As shown in FIG. 3, the horizontal connector C2 is disposed between the pair of left and right vertical frames 14a of the connector holding portions 14A and 14B of the holding jig 13. And insert. Next, when the laterally extending connector C2 is pressed downward, as shown in FIG. 4, first, both lower ends of the lock claws Ce1 of the holder Ce contact the guide surfaces 14c above the lock release bar 14b, and the guide surfaces 14c are sequentially turned off. It is expanded outward along the tapered surface, and the locked state with the stopper Cd1 is released. Subsequently, the lock pieces Ce2 on both sides of the holder Ce abut on the guide surface 14f on the upper part of the holder hooking portion 14e and sequentially displace outwardly in the same manner. When the holder Ce is further pushed in from this state, the bottom surface of the housing Cd comes into contact with the substrate 13b as shown in FIG. 5, but the locked state of the holder Ce with the locking claw Ce1 and the stopper Cd1 is released. It falls relatively to Cd. Finally, the terminal insertion surface Ca of the housing Cd is substantially at the same position as the upper end surface of the holder Ce, and the lock piece Ce2 is locked and held by the locking step 14g of the holder hooking portion 14e. At this time, the lock claw Ce
The lower end of 1 is inserted into an opening 14h formed in the substrate 13b. FIG. 6 shows a horizontal cross section in the above state.

In the state where the holder Ce is held down to the same height as the terminal insertion surface Ca of the housing Cd as described above, the other temporarily bound terminal-attached wires Wa constituting the wire harness W / H are sequentially connected to the terminals. The holder Ce does not interfere with the insertion from the insertion surface Ca, and the insertion operation can be performed without difficulty. In addition, the terminal-equipped electric wire Wa inserted into the housing Cd and taken out in the horizontal direction is held in the receiving portion 15a of the electric wire holder 15 adjacent to the vertical frame 14a, so that the height corresponding to the rising position of the holder Ce is maintained. Wire is bundled by the tape T. For this reason, even when the holder Ce is returned to the raised position, the wires can be laid out in a predetermined form without the wires being stretched (FIG. 8).

When the wiring connector C2 is removed from the connector holding portions 14A and 14B after all the wiring work is completed, the operating portions Ce3 of the lock pieces Ce2 on both sides are gripped and bent inward. The lock piece Ce2 expands, and the locked state with the locking step 14g is released. Next, by lifting the holder Ce, the lateral connector C2 is detached from the connector holding portions 14A, 14B, and at the same time, the holder Ce returns to a position relatively raised with respect to the housing Cd.

FIGS. 7A and 7B show another embodiment of the pair of connector holders 24A and 24B. The pair of connector holders 24A and 24B are connected to the horizontal connector C2.
The central portion of the mating connector C3 to be fitted is cut off (hatched portion in the figure), and the left and right sides left are fixed at predetermined intervals on the substrate 13b. Note that the vertical frame 24a,
The main components such as the lock release lever 24b and the holder hooking portion 24e are slightly different in shape from those in the above embodiment, but the functions and the fitting dimensions of the housing Cd and the holder Ce are the same.

[0021]

As is clear from the above description, in the holding jig of the horizontal connector according to the present invention, the locking of the housing and the holder can be performed only by setting the horizontal connector provided with the holder to the holding jig. Is released, the holder can be lowered to a position substantially the same as the terminal insertion surface. Therefore, the work of inserting the electric wire with terminal into the lateral connector can be efficiently performed.
