Description

  The present invention relates to an assembly jig for a connector used when connecting a connector to an electric wire, and an assembly drawing board with an assembly jig for the connector.

  Conventionally, in the manufacture of a wire harness, a plurality of electric wires are routed on an assembly drawing board in which a routing route is set in advance, and terminal fittings connected to the respective wires are respectively inserted into predetermined connector housings. The operation of connecting the connector to the electric wire is performed (connector assembly process).

  Then, when the connector assembly process is completed, it is inspected whether the terminal fitting is not left in the half-inserted state (connector inspection process). This inspection is performed, for example, by setting a connector in the continuity inspection apparatus described in Patent Document 1. This connector has a lance that is locked to the terminal fitting and prevents the terminal fitting from coming off. The lance is elastically bent by being pushed by the terminal fitting during the insertion of the terminal fitting, so that the terminal fitting is properly positioned. When it reaches, it will be elastically restored and locked to the terminal fitting.

The continuity inspection device has a connector fitting chamber in which a connector can be fitted, and an insertion inspection pin protruding into the connector fitting chamber. When the connector with the terminal fitting half-inserted is fitted into the connector fitting chamber, the elastically bent lance comes into contact with the tip of the insertion inspection pin, and the fitting of the connector proceeds. The lance pushes the insertion inspection pin backward. When the insertion inspection pin is pushed backward, the circuit is cut off and half-insertion of the terminal fitting is detected.

By the way, as described above, since it takes time and labor to separate the connector assembly process and the connector inspection process, a countermeasure has been desired.
The present invention has been completed based on the above circumstances, and provides a connector assembly jig and an assembly drawing board with a connector assembly jig that can save time and labor for connector assembly and inspection. The purpose is to do.

The connector assembly jig of the present invention includes a lance for locking the terminal fitting integrally with the outer wall of the connector housing, and when the terminal fitting is half inserted, the lance is displaced in a direction protruding from the outer wall, and the terminal An assembly jig for a connector that returns in the reverse direction when the metal fitting reaches a proper position, and a jig body having a housing housing chamber for housing the connector housing, and an inner portion of the housing housing chamber among the jig bodies. A half-insertion detecting member that is provided on a wall surface and detects that the lance protrudes from the outer wall, and the half-insertion detection member is tiltable about a fulcrum, and one end side of the half-insertion detection member is the outer wall When pressed by the lance displaced in the direction protruding from the other end side, the other end side is displaced toward the housing accommodating chamber side, and the connector housing from the housing accommodating chamber is When the one end side is not pressed by the lance, the other end side is arranged at a position retracted from the housing accommodating chamber to allow the connector housing to be detached. It made especially with the features.

  According to such a configuration, the connector housing is accommodated in the housing housing chamber of the jig body, and by inserting the terminal fitting connected to the electric wire into the connector housing, the connection between the electric wire and the connector is completed, Further, when the terminal fitting is half-inserted, it is detected by the half-insertion detecting member. That is, the connector assembly process for connecting the connector to the electric wire and the connector inspection process for detecting half-insertion of the terminal fitting are performed at the same time. Therefore, the assembly and inspection of the connector is performed compared to the case where these processes are performed separately. Can save time and effort.

Also, when the terminal fitting is half-inserted, the half-insertion detecting member is in the restricting posture and restricts the connector housing from being detached. When the terminal fitting is in the proper position, the half-insertion detecting member is in the allowable posture. Allow detachment of housing. That is, whether or not the terminal fitting is half-inserted can be detected depending on whether or not the connector housing is restricted from being allowed to be detached from the housing accommodating chamber. As described above, since the half insertion of the terminal fitting can be detected by a mechanical mechanism, a power source or the like is not required compared to the case of detecting by an electric mechanism, and the assembly jig can be downsized. .

  The half insertion detection member may include an elastic member that elastically deforms as the tilting posture is tilted to the restriction posture and generates an elastic restoring force in a direction that tilts the half insertion detection member to the allowable posture. As a result, the half-insertion detecting member that has been pressed by the lance and has become in the restricted posture is allowed to be in the allowed posture by the elastic restoring force of the elastic member when the pressure from the lance is released.

(This portion is referred to as a pressing portion 53). Thereby, the fixed portion 36 </ b> A of the reversing spring 36 is restricted from displacement in the front / rear / left / right and up / down directions.

  The assembly jig J of the connector 10 is provided on a work board (referred to as assembly drawing board B) used when manufacturing the wire harness. The assembly drawing board B corresponds to a full-scale design drawing, and has a substantially rectangular shape that is long in the extending direction of the trunk line A of the wire harness. And on the assembly drawing board B, many electric wire holders (not shown) for arranging the electric wire W are provided, and the portion of the assembly drawing board B where the trunk line A of the wire harness is arranged. An assembly jig J is provided in the vicinity (see FIG. 5).

Next, the operation | work which connects the connector 10 to the electric wire W using the assembly jig | tool J of the connector 10 of this embodiment is demonstrated.
First, the connector housing 11 of the connector 10 connected to the electric wire W is set on the assembly jig J (see FIG. 6). The connector housing 11 has no terminal fitting 20 inserted therein, and the lance 12 does not protrude from the outer wall 11A. When the connector housing 11 is pushed into the housing housing chamber 31 of the assembly jig J from the rear, the connector housing 11 moves forward in the housing housing chamber 31 without tilting the detection arm 40. When the connector housing 11 is pushed to a position where it abuts against the front wall 30D of the jig body 30, the front end portion of the lance 12 contacts the first pressed surface 43 of the detection arm 40, and the rib 15 of the connector housing 11 is detected by the detection arm. It will be in the state facing 40 engaging parts 45 in the up-down direction. Thus, the connector housing 11 is accommodated in the housing accommodating chamber 31, and the setting to the assembly jig J is completed.

  Next, the terminal fittings 20 are sequentially inserted into the cavities 13 of the connector housing 11 set in the assembly jig J (see FIG. 7). When the terminal fitting 20 is inserted into the cavity 13 from the rear and the locked portion 23 of the terminal fitting 20 reaches below the lance 12, the lance 12 is pushed by the locked portion 23 and elastically bends upward to detect the detection arm. The first pressed surface 43 of 40 is pushed upward to protrude from the outer wall 11A (see FIG. 8). The detection arm 40 whose first pressed surface 43 is pressed is tilted while elastically deforming the spring portion 36B of the reversing spring 36, and the engaging portion 45 is engaged with the rib 15 (restricted posture).

  When the terminal fitting 20 is further inserted into the back, the terminal fitting 20 advances while the detection arm 40 is tilted, and eventually reaches a proper position (see FIG. 9). When the terminal fitting 20 reaches the proper position, the locked portion 23 of the terminal fitting 20 passes forward through the locking projection 12A of the lance 12, and the lance 12 is elastically restored and does not protrude from the outer wall 11A. become. At the same time, the detection arm 40 returns to the allowable posture due to the elastic restoring force of the reversal spring 36, and the engaging portion 45 is separated from the rib 15 (disengaged state). When the terminal fitting 20 reaches the proper position, the front end of the terminal fitting 20 is close to the front wall surface of the cavity 13, and substantially the entire portion of the terminal portion 14 </ b> A of the bus bar 14 that protrudes into the cavity 13 is connected 22. In this state, the bus bar 14 and the terminal fitting 20 are properly connected.

  When all the terminal fittings 20 have been inserted, the connector housing 11 is pulled out from the assembly jig J backward. Here, when even one terminal fitting 20 is half-inserted, the lance 12 is kept standing on the locking projection 12A of the terminal fitting 20, and the detection arm 40 is tilted to be in a regulating posture. (See FIGS. 11 and 12). For this reason, when the connector housing 11 is to be pulled out from the assembly jig J, the rib 15 is hooked on the engaging portion 45 and the pull-out is restricted, whereby it is possible to detect that the terminal fitting 20 is half-inserted.

  When it is detected that the terminal fitting 20 is half-inserted, the half-inserted terminal fitting 20 is pushed in until it reaches a proper position. Then, the lance 12 is elastically restored to be in a natural state, the detection arm 40 is in an allowable posture, and the engagement between the engagement portion 45 and the rib 15 is released. As a result, the connector housing 11 is pulled out of the assembly jig J without the rib 15 being caught by the engaging portion 45. Thus, it is possible to obtain the connector 10 in a state where all of the terminal fittings 20 to be inserted into the connector housing 11 are inserted at regular positions.

According to the present embodiment configured as described above, the following effects can be obtained.
The assembly jig J of the present embodiment is provided on a jig body 30 having a housing housing chamber 31 for housing the connector housing 11, and on the inner wall surface of the housing housing chamber 31 of the jig body 30. Is provided with a detection arm 40 for detecting that the projection protrudes from the outer wall 11A.

  Therefore, when the terminal fitting 20 connected to the electric wire W is inserted into the connector housing 11 with the connector housing 11 set in the housing accommodating chamber 31 of the assembly jig J, the connection between the electric wire W and the connector 10 is completed. At the same time, when the terminal fitting 20 is half-inserted, the detection arm 40 detects it. That is, since the assembly process of the connector 10 that connects the connector 10 to the electric wire W and the inspection process of the connector 10 that detects half-insertion of the terminal fitting 20 are performed at the same time, compared to the case where these processes are performed separately, The trouble of assembling and inspecting the connector 10 can be saved.

  The detection arm 40 is tiltable about a fulcrum. When one end side of the detection arm 40 is pressed by the lance 12 displaced in a direction protruding from the outer wall 11A, the other end side is displaced toward the housing accommodation chamber 31 side. When the one end side is not pressed by the lance 12, the other end side is arranged at a position retracted from the housing accommodating chamber 31 to prevent the connector housing 11 from being detached. It becomes an allowable posture.

  Therefore, when the terminal fitting 20 is half-inserted, the detection arm 40 is in a restricted posture to restrict the detachment of the connector housing 11, and when the terminal fitting 20 reaches a proper position, the detection arm 40 is in an allowable posture. The connector housing 11 is allowed to be detached. That is, whether or not the terminal fitting 20 is half-inserted can be detected depending on whether the detachment of the connector housing 11 from the housing accommodating chamber 31 is restricted or allowed. As described above, since the half-insertion of the terminal fitting 20 can be detected by a mechanical mechanism, a power source or the like is not required as compared with the case of detecting by an electric mechanism, and the assembly jig J can be downsized. Can do.

  Further, the assembly jig J includes a reversing spring 36 that elastically deforms as the detection arm 40 tilts to the regulation posture and generates an elastic restoring force in a direction that tilts the detection arm 40 to the allowable posture. Therefore, the detection arm 40 that is pressed by the lance 12 to be in the restricted posture is in the allowable posture by the elastic restoring force of the reversing spring 36 when the pressure from the lance 12 is released.

Further, since the assembly jig J has the cover body 50 that covers the side of the detection arm 40 opposite to the housing housing chamber 31, the detection jig 40 is prevented from being tilted by being pushed by anything other than the lance 12. be able to.
And since the assembly jig J is provided in the assembly drawing board B by which the electric wire W which comprises a wire harness is wired, when manufacturing a wire harness, the assembly jig J of the connector 10 is used. The assembly process of the connector 10 and the inspection process can be performed simultaneously.

A structure in which the detection arm returns from the tilting posture to the horizontal posture by its own weight without providing the reversing spring may be employed.

  (2) In the above embodiment, the reversing spring 36 is provided above the front end portion of the detection arm 40 and presses the front end portion of the detection arm 40 downward by an elastic restoring force. For example, the elastic member may be provided below the front end portion of the detection arm and pull the front end portion of the detection arm downward by an elastic restoring force, or above or below the rear end portion of the detection arm. It may be provided such that the rear end of the detection arm is pulled upward or pressed upward by an elastic restoring force.

(3) In the above-described embodiment, the half-insertion detection member is the detection arm 40. However, the present invention is not limited to this, and for example, a sensor that can detect whether or not the lance protrudes from the outer wall may be used.
(4) In the above embodiment, the engagement portion 45 of the detection arm 40 is a recess that can be engaged with the rib 15 of the connector housing 11, but this is not a limitation, and the engagement portion engages with the connector housing. For example, the engaging portion may be a protruding wall or the like that is disposed to face the rear end surface of the connector housing when the detection arm 40 is in the restricting posture.
(5) In the above embodiment, the reversing spring 36 (elastic member) is a leaf spring, but is not limited thereto, and may be a coil spring, for example.
