Description

[Technical field]

[0001] The present invention relates to a structure for detecting different part numbers. [Background technology]

[0002] A wide variety of electronic devices are mounted on automobiles, and wire harnesses are arranged to transmit power, control signals, etc. to the electronic devices. The wire harness includes a plurality of electric wires and connectors, and is connected to the electronic devices and other wire harnesses by fitting the connectors to the connectors of the electronic devices or the connectors of other wire harnesses.

[0003] A joint connector used in such a wire harness is configured to include a substantially flat bus bar having a structure in which multiple (in this example, two) tongue-shaped tab terminals extend from a flat, band-shaped base portion, and a connector housing that accommodates and holds the bus bar (see, for example, Patent Document 1).

[0004] The connector housing has two rows of flat, narrow bus bar locking grooves on its rear end surface for fitting and locking the bus bars, and an opening on its front surface through which the tab terminals of the bus bars fitted in the bus bar locking grooves protrude. The connector housing also has a jig guide groove on its rear end surface that is perpendicular to the bus bar locking grooves and allows the bus bars to be inserted into the bus bar locking grooves.

[0005] When assembling such a joint connector, the tab terminals of the bus bar are inserted close to the bus bar locking grooves, and the bus bar insertion jig is brought close to the jig guide grooves to press the board portion of the bus bar, so that the bus bar is fitted and locked into the bus bar locking grooves and is housed and held in the connector housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 7. Figure 1 is an exploded perspective view showing a connector 1 constituting a different product number detection structure 10 according to one embodiment of the present invention.

[0013] 6 and 7, the different part number detection structure 10 of this embodiment is for detecting whether or not the combination of connector 1 and pushing jig 6 is correct, and includes connector 1 and pushing jig 6 for assembling connector 1. The different part number detection structure 10 is for using the pushing jig 6 to detect whether or not the housing 3 constituting connector 1 is a housing 3 assigned with a desired part number.

[0014] 1 to 3, connector 1 includes a plurality of bus bars 2 each having a plurality of tab terminals 20, and housing 3 having bus bar accommodating chambers 30 (shown in FIG. 3) that accommodate the plurality of bus bars 2. As shown in FIGS. 1 and 3, connector 1 is configured such that, with bus bars 2 accommodated in bus bar accommodating chambers 30, each tab terminal 20 is inserted and connected to a female terminal fitting 7 (shown in FIG. 1, hereinafter referred to as female terminal 7).

[0015] In such a connector 1, there are a plurality of housings 3A, 3B (3) having different numbers of joint poles, different arrangements of the bus bars 2, and different shapes of the bus bar accommodating chambers 30, and these housings 3A, 3B are assigned different product numbers and managed. The pushing jig 6 of this embodiment corresponds to the housing 3A, and the housing 3A and the pushing jig 6 are used as a set. The housings 3A, 3B differ in that the positions of the insulating walls 42 described below are different. The pushing jig 6 detects whether the housing 3 is of the desired product number according to the positions of the insulating walls 42 in the housing 3. Hereinafter, only when a distinction is necessary, the housings will be referred to as 3A, 3B, and otherwise, the housings will be referred to as 3.

[0016] As shown in Figures 1 and 3, the bus bar 2 is integrally formed by having a rectangular plate-shaped base 21 and a plurality of tab terminals 20 extending forward X1 from predetermined positions on the base 21 in the left-right direction Y (the longitudinal direction of the base 21).

[0017] As shown in Figs. 1 and 3, each tab terminal 20 is provided with a pair of extending pieces 22, 22 extending from both sides in the width direction Y. The pair of extending pieces 22, 22 are formed so that the amount of extension in the width direction Y gradually decreases toward the front X1. As shown in Fig. 3, each tab terminal 20 is configured to abut against a displacement restricting portion 44 of the accommodation space forming portion 4, which will be described later, when the bus bar 2 is accommodated in the bus bar accommodating chamber 30, thereby restricting the displacement of each tab terminal 20 in the width direction Y. In this embodiment, the number of tab terminals 20 included in each bus bar 2 is different. The number of tab terminals 20 included in each bus bar 2 is 3 to 6.

[0018] In this embodiment, the direction in which each tab terminal 20 extends is referred to as the front-rear direction X, and two directions perpendicular to the front-rear direction X are referred to as the direction Y and the direction Z. In the front-rear direction X, the tip side of each tab terminal 20 may be referred to as the "front X1", and the base end side in the opposite direction may be referred to as the "rear X2". The direction Y is the width direction Y of the tab terminal 20 (sometimes referred to as the left-right direction Y), and the direction Z is the plate thickness direction Z of each tab terminal 20 (sometimes referred to as the up-down direction). One of the plate thickness directions Z may be referred to as the "upper Z1", and the other may be referred to as the "lower Z2".

[0019] The housing 3 is made of, for example, insulating resin. As shown in Fig. 3, the housing 3 includes a rectangular cylindrical housing main body 31 extending in the front-rear direction X (the axial direction of the cylinder), an accommodation space forming portion 4 that divides the internal space of the housing main body 31, a plurality of bus bar accommodating chambers 30 formed by the accommodation space forming portion 4, and a plurality of female terminal accommodating chambers 5.

[0020] As shown in FIG. 4, the housing body 31 is configured to have an upper wall 31A, a lower wall 31B facing the lower side Z2 of the upper wall 31A, and a pair of side walls 31C, 31C that are continuous with the upper wall 31A and the lower wall 31B and face each other in the left-right direction Y.

[0021] As shown in Figures 3 and 4, the accommodating space forming portion 4 comprises upper and lower partition walls 41 that divide the housing main body 31 in the vertical direction Z, an insulating wall 42 that insulates the bus bars 2 from each other in the space partitioned by the upper and lower partition walls 41, left and right partition walls 43 (shown in Figure 3) that separate a plurality of tab terminal accommodating chambers 33 (described later) provided in each bus bar accommodating chamber 30 in the space partitioned by the insulating wall 42, a displacement regulating portion 44 (shown in Figure 3) that regulates displacement of the bus bar 2 provided in each bus bar accommodating chamber 30, and a bus bar clamping portion 45 (shown in Figure 4) that clamps and supports the bus bar 2 provided in each bus bar accommodating chamber 30.

[0022] 4, two upper and lower partition walls 41 are provided in this embodiment, and the housing main body 31 is divided into three spaces in the vertical direction Z by the upper and lower partition walls 41. Each upper and lower partition wall 41 is provided extending on a plane including the front-rear direction X and the left-right direction Y.

[0023] 3, the upper and lower partition walls 41 (and the lower wall 31B of the housing body 31) are provided with lances 410 for engaging the female terminals 7 accommodated in the female terminal accommodating chambers 5. One lance 410 is provided for each female terminal accommodating chamber 5. In a natural state, the lances 410 are formed to extend obliquely upward Z1 as they proceed toward the rear X2 of each female terminal accommodating chamber 5.

[0024] 3 and 4, the insulating wall 42 is provided contiguous to the lower side Z2 of the upper wall 31A (or the upper and lower partition wall 41) of the housing body 31, and is provided extending in a plane including the front-rear direction X and the up-down direction Z. A tip surface 42S at the rear X2 of this insulating wall 42 is at the same position as the rear end of the bus bar accommodating chamber 30 in the front-rear direction X, and is configured to be located rearward X2 of the rear end of the bus bar 2 when the bus bar 2 is accommodated in the bus bar accommodating chamber 30 described later.

[0025] 3, the left and right partition walls 43 are provided contiguous to the lower portion Z2 of the upper wall 31A (or the upper and lower partition walls 41) of the housing body 31, and extend in a plane including the front-rear direction X and the up-down direction Z. The rear ends of the left and right partition walls 43 are configured to be located forward X1 of the base 21 of the bus bar 2 and rearward X2 of the front ends of the tab terminals 20 when the bus bar 2 is accommodated in a bus bar accommodating chamber 30 described later.

[0026] 3(B), the displacement restricting portion 44 is provided on the insulating wall 42 and the left-right partition wall 43, and is provided at a position where it comes into contact with a pair of extending pieces 22, 22 provided on each tab terminal 20 when each bus bar 2 is accommodated in the bus bar accommodating chamber 30. The displacement restricting portion 44 is formed so that the amount of protrusion increases toward the front X1 in the left-right direction Y, and is configured to restrict displacement of each tab terminal 20 in the left-right direction Y when the pair of extending pieces 22, 22 come into contact with each other, thereby positioning each tab terminal 20 at a predetermined position in the left-right direction Y.

[0027] As shown in FIG. 4, the bus bar clamping portion 45 is configured to have a pair of clamping pieces 45A, 45B that clamp and hold the base portion 21 of the bus bar 2 between them.

[0028] 4, a plurality of bus bar clamping portions 45 (the same number as the left and right partition walls 43) are provided. The plurality of bus bar clamping portions 45 are provided at intervals (hereinafter, sometimes referred to as jig guide grooves 34) in the left-right direction Y.

[0029] The clamping pieces 45A, 45B are formed in a flat plate shape and are provided opposite each other in the up-down direction Z. The clamping pieces 45A, 45B are provided extending on a plane including the front-rear direction X and the left-right direction Y. Furthermore, the clamping pieces 45A, 45B are formed continuous with the upper and lower ends of the left-right partition walls 43 and extend rearward X2.

[0030] Each of the multiple bus bar accommodating chambers 30 is configured to accommodate a bus bar 2, as shown in FIG. 4. In this embodiment, the bus bar accommodating chambers 30 are stacked in three stages. In the following, as shown in FIG. 4, the bus bar accommodating chamber 30 located at the upper Z1 may be referred to as the "first bus bar accommodating chamber 30A," the bus bar accommodating chamber 30 located at the lower Z2 may be referred to as the "third bus bar accommodating chamber 30C," and the bus bar accommodating chamber 30 located between the first bus bar accommodating chamber 30A and the third bus bar accommodating chamber 30C may be referred to as the "second bus bar accommodating chamber 30B."

[0031] 3, each busbar accommodating chamber 30 includes a base accommodating chamber 32 for accommodating the base 21, and a plurality of tab terminal accommodating chambers 33 for accommodating the tab terminals 20. The base accommodating chambers 32 are provided continuous to the rear X2 of each tab terminal accommodating chamber 33, and are also provided continuous in the left-right direction Y.

[0032] Each tab terminal accommodating chamber 33 is provided continuously from a predetermined position in the left-right direction Y of the base accommodating chamber 32 to the front X1. Each tab terminal accommodating chamber 33 is provided extending in the front-rear direction X so as to be able to accommodate each tab terminal 20.

[0033] 3(A), the multiple female terminal accommodating chambers 5 are arranged side by side in the left-right direction Y. Each female terminal accommodating chamber 5 is arranged extending in the front-rear direction X so as to be able to accommodate each female terminal 7. That is, each female terminal accommodating chamber 5 and each tab terminal accommodating chamber 33 are arranged side by side on a straight line, and each female terminal accommodating chamber 5 is arranged on the front X1 side of each tab terminal accommodating chamber 33.

[0034] When the female terminal 7 is inserted into such a female terminal accommodating chamber 5, the female terminal 7 abuts against the lance 410 and is deflected temporarily, and when the insertion proceeds further and the female terminal 7 reaches an appropriate position, the lance 410 is restored to its original state and the female terminal 7 is locked and accommodated in the female terminal accommodating chamber 5. With the female terminal 7 accommodated in each female terminal accommodating chamber 5, each bus bar 2 is accommodated in each bus bar accommodating chamber 30, and each tab terminal 20 is inserted into each tab terminal accommodating chamber 33, so that the female terminal 7 and the tab terminal 20 are electrically connected to each other.

[0035] 4, the housing 3 is provided with a jig guide groove 34 into which a push-in portion 61 of a push-in jig 6 described later is inserted. The jig guide groove 34 is located between the bus bar clamping portions 45 adjacent in the left-right direction Y, and is formed as a space into which the push-in portion 61 of the push-in jig 6 described later is inserted.

[0036] 5, the pressing jig 6 includes a rectangular parallelepiped jig body 60, a pressing portion 61 provided so as to protrude forward X1 from a front surface 60f (contact surface) of the jig body 60, and a different part number detection portion 62 (detection portion, abutment portion). The pressing portion 61 is provided on a protrusion extending in the up-down direction Z, and is provided at an interval in the left-right direction Y so as to correspond to the jig guide groove 34 provided in the housing 3.

[0037] Such a protruding dimension (dimension in the front-rear direction X) of each of the pushing portions 61 is configured to correspond to a distance from the rear end of the busbar 2 to a predetermined position in the busbar accommodating chamber 30 from the rear end of the busbar accommodating chamber 30 (the same position as the tip surface 42S of the insulating wall 42 in the front-rear direction X). As a result, when the pushing jig 6 is pressed against the housing 3, the busbar 2 is pushed by the pushing portions 61, and when the busbar 2 pushed by the pushing portions 61 reaches a predetermined position in the busbar accommodating chamber 30, the front surface 60f of the jig body 60 abuts against the rear end of the busbar accommodating chamber 30, i.e., the tip surface 42S of the insulating wall 42, and the movement of the pushing jig 6 toward the housing 3 is stopped.

[0038] As shown in Fig. 5, two different part number detection units 62 are provided in this embodiment. The two different part number detection units 62 are provided protruding from the front surface 60f of the jig body 60 toward the front X1. In this embodiment, the different part number detection units 62 are configured to be immovable (undisplaceable). The different part number detection unit 62 is located in the center in the left-right direction Y and is configured to bridge between the push-in units 61, 61 adjacent in the left-right direction Y. The two different part number detection units 62 are provided side by side in the up-down direction Z, and the different part number detection unit 62 on the upper Z1 side is provided at a position corresponding to the first bus bar accommodating chamber 30A, and the different part number detection unit 62 on the lower Z2 side is provided at a position corresponding to the second bus bar accommodating chamber 30B.

[0039] As shown in FIG. 6(A), when the pushing portion 61 of the pushing jig 6 is brought close to the jig guide groove 34 and the pushing jig 6 is pressed against the housing 3A(3), if the insulating wall 42 is not in a position to abut against the different part number detection portion 62, the pushing portion 61 and the different part number detection portion 62 push the busbar 2 to a predetermined position in the busbar accommodating chamber 30 as shown in FIG. 6(B). That is, the pushing of the busbar 2 by the pushing portion 61 is permitted. Since the pushing of the busbar 2 by the pushing portion 61 is permitted in this manner, the worker detects that the housing 3A and the pushing jig 6 are a regular combination and that the housing 3A is the housing 3A with the desired part number. Note that hatching showing a cross section of the connector 1 is omitted in FIG. 6(B).

[0040] As shown in FIG. 7(A), when the pushing portion 61 of the pushing jig 6 is brought close to the jig guide groove 34 and the pushing jig 6 is pressed against the housing 3B(3), if the insulating wall 42 is provided at a position where the different part number detection portion 62 comes into contact with the different part number detection portion 62, the different part number detection portion 62 comes into contact with the insulating wall 42 as shown in FIG. 7(B), and the movement of the pushing jig 6 is restricted. That is, the pushing of the busbar 2 by the pushing portion 61 is restricted. By restricting the pushing of the busbar 2 by the pushing portion 61 in this manner, the front surface 60f of the jig body 60 and the tip surface 42S of the insulating wall 42 are separated from each other to form a gap S. In this manner, the worker detects that the housing 3B and the pushing jig 6 are an irregular combination and that the housing 3B is a housing 3B of a different part number. In FIG. 7(B), hatching showing a cross section of the connector 1 is omitted.

[0041] The procedure for assembling such a connector 1 using a push-in jig 6 will be described with reference to FIGS. 6(A) and 6(B).

[0042] The tip of each tab terminal 20 of each bus bar 2 is inserted close to the rear end of each bus bar accommodating chamber 30. Here, the pushing portion 61 of the pushing jig 6 is brought close to the jig guide groove 34, and the pushing jig 6 is pressed against the housing 3A(3). As a result, the pushing portion 61 and the different part number detection portion 62 push the bus bar 2, and the bus bar 2 reaches a predetermined position in the bus bar accommodating chamber 30. The front surface 60f of the jig body 60 abuts against the tip surface 42S of the insulating wall 42, and the bus bar 2 reaches a predetermined position in the bus bar accommodating chamber 30, and the movement of the pushing jig 6 into the housing 3 is stopped. In this way, the different part number detection portion 62 does not abut against the insulating wall 42, and the pushing of the bus bar 2 by the pushing portion 61 is allowed, so that the worker detects that the housing 3A and the pushing jig 6 are a regular combination and that the housing 3A is the housing 3A with the desired part number.

[0043] Here, assuming that the pushing portion 61 of the pushing jig 6 is brought close to the jig guide groove 34 as shown in Fig. 7(A) and the pushing jig 6 is pressed against the housing 3B, if the different part number detection portion 62 abuts against the insulating wall 42 as shown in Fig. 7(B), further movement of the pushing jig 6 is restricted. That is, the pushing of the bus bar 2 by the pushing portion 61 is restricted. As a result of the pushing of the bus bar 2 by the pushing portion 61 being restricted in this manner, the worker detects that the housing 3B and the pushing jig 6 are an incorrect combination and that the housing 3B is a housing 3B with a different part number.

[0044] In this way, when bus bar 2 reaches a predetermined position in bus bar accommodating chamber 30 and the worker detects that housing 3A is housing 3A with the desired part number, substantially at the same time, each extension piece 22 of each tab terminal 20 of bus bar 2 abuts against displacement restricting portion 44 of bus bar accommodating chamber 30, restricting displacement of each bus bar 2 in left-right direction Y. Also, each tab terminal 20 is inserted into the female terminal 7, and the female terminal 7 and each tab terminal 20 are electrically connected. As a result, bus bar 2 is accommodated in bus bar accommodating chamber 30. In this manner, connector 1 is assembled.

[0045] According to the above-mentioned embodiment, when the pushing jig 6 is pressed against the housing 3, if the different part number detection unit 62 (detection unit) does not abut against the insulating wall 42, it is detected that the housing 3 and the pushing jig 6 are a regular combination, and when the different part number detection unit 62 abuts against the insulating wall 42 when the pushing jig 6 is pressed against the housing 3, it is detected that the housing 3 and the pushing jig 6 are an irregular combination. This makes it possible to confirm that the housing 3 has a desired part number without providing a dedicated shape. That is, since the housing 3 can be identified without providing a dedicated shape, a product can be provided in a compact shape. In addition, by changing the position and number of the different part number detection unit 62 (abutment unit) of the pushing jig 6 according to the position of the insulating wall 42 in the housing 3, it is possible to accommodate many combinations. This makes it possible to realize a configuration that allows the housing 3 to be identified at low cost.

[0046] Further, the different part number detection portion 62 (contact portion) is provided protruding from the jig body 60, and when the housing 3 and the pushing jig 6 are a regular combination, the different part number detection portion 62 does not contact the insulating wall 42 and the pushing of the busbar 2 by the pushing portion 61 is permitted, and when the housing 3 and the pushing jig 6 are an irregular combination, the different part number detection portion 62 contacts the insulating wall 42 and restricts the pushing of the busbar 2 by the pushing portion 61. According to this, when the pushing of the busbar 2 by the pushing jig 6 is permitted, the worker detects that the connector 1 (i.e., the housing 3) is a desired part number, and when the pushing of the busbar 2 by the pushing jig 6 is restricted, the worker detects that the connector 1 (i.e., the housing 3) is a different part number that is not the desired part number. In this way, in the process of assembling the connector 1, it is possible to detect whether the connector 1 (i.e., the housing 3) is a different part number without increasing the number of work steps, and therefore it is possible to reduce the assembly cost.

[0047] Furthermore, the jig body 60 has a front surface 60f (contact surface) that can come into contact with the tip surface 42S of the insulating wall 42, the push-in portion 61 and the different part number detection portion 62 (abutment portion) are provided so as to protrude from the front surface 60f, and the pushing jig 6 is configured so that when the pushing of the bus bar 2 by the push-in portion 61 is permitted, the front surface 60f abuts against the tip surface 42S of the insulating wall 42 at a position where the pushing of the bus bar 2 is completed. In this way, when the front surface 60f of the jig body 60 abuts against the tip surface 42S of the insulating wall 42, the worker recognizes that the pushing of the bus bar 2 is completed. This can improve the ease of assembly of the connector 1.

[0048] The present invention is not limited to the above-described embodiment, but includes other configurations that can achieve the object of the present invention, and the following modifications are also included in the present invention.

[0049] In the above embodiment, the different part number detection unit 62 (detection unit, abutment unit) is configured to be immovable (undisplaceable), but the present invention is not limited to this. The detection unit may be configured as a movable probe pin. In this case, when the probe pin (detection unit) does not abut against the insulating wall 42 and does not displace (move) when the pressing jig 6 is pressed against the housing 3, the worker can detect that the housing 3 and the pressing jig 6 are properly combined and that the housing 3 is a housing 3 with a desired part number, and when the probe pin abuts against the insulating wall 42 and displaces (moves) when the pressing jig 6 is pressed against the housing 3, the worker can detect that the housing 3 and the pressing jig 6 are not properly combined and that the housing 3 is a housing 3 with a different part number.

[0050] In addition, the best configurations and methods for implementing the present invention are disclosed in the above description, but the present invention is not limited thereto. That is, the present invention has been mainly illustrated and described with reference to specific embodiments, but those skilled in the art can make various modifications to the above-described embodiments in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and purpose of the present invention. Therefore, the descriptions limiting the shapes, materials, etc. disclosed above are illustrative descriptions for the purpose of facilitating understanding of the present invention, and do not limit the present invention, and therefore descriptions of the names of components that are free of some or all of the limitations on the shapes, materials, etc. are included in the present invention.
