Description

  The present invention relates to a splice absorbing connector for eliminating, for example, a joint (splice) between electric wires branched from a sub-harness, and in particular, a splice absorbing device having a structure in which a plurality of identical sub-housings are stacked to form the entire connector housing. The present invention relates to a connector, a correctness determination apparatus that determines whether the stacking order of the sub-housings is correct, and a determination method that determines whether the stacking order of the subhousings is correct using the correctness determination apparatus.

Conventional joint absorption connectors and splice absorption connectors cannot flexibly respond to changes in the number of wires branched from the sub-harness and connection patterns, and the overall size of the connector increases as the number of in-vehicle circuits increases and complexity increases. In view of such a problem, the present applicant has proposed a splice absorbing connector as shown in FIGS.
Japanese Patent Application No. 10-318888

FIG. 9 is an exploded perspective view showing the splice absorbing connector of Patent Document 1.
FIG. 10 is a cross-sectional view of the splice absorbing connector assembled, and FIG. 11 is a perspective view of terminals constituting the splice absorbing connector.

  Further, FIG. 12 is a conceptual diagram showing a connection state of the sub-harness by the splice absorbing connector.

  9, 10, and 12, a splice absorbing connector 100 includes a plurality of terminals 10 connected to electric wires 31 a and 32 a branched from two or more sub-harnesses 31 and 32, and a connector housing that houses these terminals 10. 20.

  The terminal 10 shown in FIG. 9 includes a press-contact portion 11 for press-connecting the electric wires 31a and 32a, a flat substrate-like contact portion 12, and an elastic contact portion 13 coupled to the substrate-like contact portion 12. Have

  As shown in FIGS. 9 and 10, the connector housing 20 includes two sub-housings 20A and 20B that can be stacked, an upper lid (lid) 24 that is mounted on the upper sub-housing 20A, and a lower sub-housing. It is comprised with the lower cover body (lid body) 25 attached under 20B.

  The sub-housings 20 </ b> A and 20 </ b> B both have the same configuration and have a plurality of terminal accommodating chambers 21 for accommodating the terminals 10.

  These terminal accommodating chambers 21 are provided with a lower opening (opening) 21 a and an upper opening (opening) 21 b respectively corresponding to the substrate-like contact portion 12 and the elastic contact portion 13 of the terminal 10.

  The terminal 10 of the electric wire 31a branched from the sub-harness 31 shown in FIG. 12 is accommodated in the terminal accommodating chamber 21 of the sub-housing 20A. The terminal accommodating chamber 21 of the sub-housing 20B is accommodated from the sub-harness 32 shown in FIG. The terminal 10 of the branched electric wire 32a is accommodated.

  When the terminal 10 is accommodated in the terminal accommodating chamber 21, as shown in FIG. 10, the substrate-like contact portion 12 is exposed from the lower opening portion 21a, and the elastic contact portion 13 protrudes from the upper opening portion 21b.

  Further, as shown in FIG. 10, a locking claw 22 and a locking frame 23 are integrally formed on both sides of the sub-housings 20A and 20B.

  When the sub housings 20A and 20B are stacked, the locking frame 23 of the upper sub housing 20A meshes with the locking claws 22 of the lower sub housing 20B, and the sub housings 20A and 20B are integrated.

  At this time, the lower opening 21a of the sub-housing 20A and the upper opening 21b of the sub-housing 20B communicate with each other, and the sub-housing is connected to the board-like contact portion 12 of the terminal 10 accommodated in the terminal accommodating chamber 21 of the sub-housing 20A. The elastic contact part 13 of the terminal 10 accommodated in the terminal accommodating chamber 21 of 20B contacts.

  Thereby, the electric wires 31a and 32a of the sub-harnesses 31 and 32 shown in FIG. 12 are connected to each other (the vertical splice is absorbed).

  Here, when the terminals 10 accommodated in the adjacent terminal accommodating chambers 21 of the same sub-housing 20A or 20B are connected to each other (when the splice in the horizontal direction is absorbed), as shown in FIG. The carrier (chain band) 14 formed in the process of pressing is left and bent, and the terminals 10 are connected to each other.

  Returning to FIGS. 9 and 10, the upper lid 24 has a locking frame 23 that engages with the locking claw 22 of the sub-housing 20 </ b> A, is attached on the sub-housing 20 </ b> A, and has an upper opening 21 b of the terminal accommodating chamber 21. Block it.

  Thereby, it can prevent that the elastic contact part 13 of the terminal 10 exposes from the upper opening part 21b of 20 A of subhousings.

  On the other hand, the lower lid 25 has a locking claw 22 that meshes with the locking frame 23 of the sub-housing 20B, is attached under the sub-housing 20B, and closes the lower opening 21a of the terminal accommodating chamber 21.

  Thereby, it can prevent that the board-like contact part 12 of the terminal 10 exposes from the lower opening part 21a of the subhousing 20B.

  According to the splice absorbing connector 100 having such a configuration, the number of the electric wires 31a and 32a branched from the sub harnesses 31 and 32 and the connection pattern can be increased or decreased by increasing or decreasing the sub housings 20A and 20B constituting the connector housing 20. It can respond flexibly to changes.

  Further, since the splice absorbing connector 100 is constituted by two or more sub-housings 20A and 20B, the sub-housings 20A and 20B can be expanded in two directions, vertical and horizontal, and the circuit in the vehicle is increased and complicated. Even in this case, the entire splice absorbing connector 100 can be reduced in size.

  Furthermore, the operation of fitting the terminal 10 into the sub-housings 20A and 20B is completed for each of the sub-harnesses 31 and 32. After the sub-harnesses 31 and 32 are completed, the sub-housings 20A and 20B are simply stacked. The electric wires 31a and 32a branched from the harnesses 31 and 32 can be connected to each other, and the production efficiency of the entire wire harness can be improved.

  In addition to this, the terminals 10 accommodated in the adjacent terminal accommodating chambers 21 of the same sub-housing 20A or 20B can be connected to each other using the carrier 14 formed in the process of pressing the terminals 10 as it is. In addition, the connection and insulation between these terminals 10 can be easily selected depending on whether or not the carrier 14 is cut off.

  The splice absorbing connector proposed by the applicant of the present invention has the above-mentioned useful effects. However, since each sub-housing has the same configuration, when a large number of these sub-housings are laminated, There was a case where the order was wrong (note that when there are two sub-housings 20A and 20B as described above, there is no problem because each terminal 10 is connected in the same way regardless of which of the upper and lower stages).

  In addition, it is possible to discover that there is an error in the stacking order of these sub-housings by conducting a continuity test on the splice absorption connector. It is impossible to specifically determine whether it is wrong, and there is a problem that it takes time and effort to correct the error.

  The present invention has been made in view of the above inconveniences, and by making it possible to clearly identify the stacking order of each sub-housing in appearance, an error in the stacking order of each sub-housing can be prevented and the stacking can be performed. An object of the present invention is to provide a splice absorbing connector capable of instantaneously determining where and how the order is incorrect, and a correctness determination method and apparatus capable of reliably determining the correctness of the stacking order of the stacked sub-housings. And

In order to achieve the above-mentioned object, the invention of the composite absorbing connector according to claim 1 is connected to the electric wires branched from two or more sub-harnesses, and has an elastic contact portion coupled on the substrate-like contact portion. A terminal, and a connector housing having two or more sub-housings that can be stacked, and a terminal housing chamber of each sub-housing provided with openings corresponding to the substrate-like contact portion and the elastic contact portion, respectively. A splice absorbing connector that connects the terminals housed in the terminal housing chambers of the upper and lower sub-housings by stacking the sub-housings housing the terminals in the housing chamber,
The same number of three-dimensional marks as the stacking order are provided in parallel at equal intervals on the common surface of each subhousing that does not overlap with each other as a rank specifying part that specifies the stacking order of each subhousing, and the subhousings are stacked in the correct order. Then, the individual rank specifying portions of these sub-housings form a pattern having a certain regularity as a whole.

  According to such a configuration, when the splice absorbing connector is assembled, the sub housings are stacked in accordance with the three-dimensional mark (order specifying portion) provided on one surface of each sub housing, thereby preventing an error in the stacking order. can do.

  When the sub-housings are stacked in the correct order, the individual rank specifying portions of the sub-housings form a pattern having a certain regularity as a whole, so that correct / incorrect determination is easy.

  In particular, the order specifying section is configured such that the same number of solid marks as the stacking order are provided in parallel at equal intervals on the one surface of each sub-housing.

  According to such a configuration, at the time of assembling the splice absorbing connector, by stacking each sub-housing according to the order specifying portion (corresponding to the number of three-dimensional marks and the stacking order) provided on one surface of each sub-housing, An error in the stacking order can be prevented.

  In addition, when the sub-housings are stacked in the correct order, the order specifying portions of these sub-housings form a pattern having a certain regularity as a whole. It is possible to instantaneously determine whether the error is correct and what is wrong in the stacking order.

  That is, when the rank specifying part is the same number of solid marks as the stacking order of each sub-housing, when the sub-housings are stacked in the correct order, the three-dimensional mark of each rank specifying part is one for each sub-housing. A three-dimensional shape pattern having a certain regularity that increases gradually is formed.

  The invention for determining whether or not the stacking order is correct according to claim 2 is a determination apparatus for determining whether or not the stacking order of the sub-housings in the splice absorbing connector according to claim 1 is correct. A flexible inspection tool body, a detection pin which is provided in the inspection tool body and which can be moved back and forth corresponding to all sections of the order specifying portion of each sub-housing, and provided behind each detection pin, And a switch for individually detecting the advance and retreat of the detection pin.

  According to such a configuration, when the inspection tool main body is advanced to the side of each sub-housing, only the detection pin that is in contact with the three-dimensional mark of each rank specifying portion is retracted and the switch is pressed. Based on the operation of each switch at this time, the correctness of the stacking order of each sub-housing can be determined.

  The invention for determining whether or not the stacking order is correct according to claim 3 is a determination method for determining whether or not the stacking order of the sub-housings in the splice absorbing connector according to claim 1 is correct. A flexible inspection tool body, a detection pin which is provided in the inspection tool body and which can be moved back and forth corresponding to all sections of the order specifying portion of each sub-housing, and provided behind each detection pin, Using a stacking order correctness determination device equipped with a switch for individually detecting the advance and retreat of the detection pin, the inspection tool main body is moved forward to the stacked sub-housing side and brought into contact with the three-dimensional mark of the rank specifying portion Whether the stacking order of the sub-housings is correct or not is determined by the operation of the switch when the detection pin is retracted.

  According to this correctness / incorrectness determination method, when the inspection tool main body is moved forward to each sub-housing side using the correctness / incorrectness determination device, only the detection pin that is in contact with the three-dimensional mark of each rank specifying portion is retracted, and the switch is turned on. It is possible to easily and reliably determine whether or not the stacking order of the sub-housings is correct based on the operation of the respective switches at this time.

  If the order of stacking the sub-housings is visually determined, the rank specifying unit may be configured so that the color of one surface is different for each sub-housing. When the sub-housings are stacked in the correct order, the colors of the rank specifying portions are arranged in a predetermined order as a whole (for example, red → green → blue) to form a color pattern having a certain regularity.

  An operator can visually observe such a three-dimensional or planar shape pattern or color pattern and feel the presence or absence of a certain regularity. You can judge instantly.

  Also in this case, it is preferable that the rank specifying portion is configured such that a part or all of the one surface of each sub-housing is structurally or conceptually divided into the same number as the number of stacked stages, and each of the sub-housings among these sub-housings. The section having the same order as the stacking order is made different in appearance from the other sections.

  For example, among the sections in the rank specifying section, the sections having the same rank as the stacking order of the sub-housings may be assigned the same number as the stacking order.

  According to such a configuration, it is possible to prevent an error in the stacking order by stacking the sub-housings according to the numbers assigned to the sub-housings.

  Further, when the sub-housings are stacked in the correct order, the number of each rank specifying portion is obliquely arranged on the diagonal line of each sub-housing, and a pattern having a certain regularity as a whole is formed.

  For example, a configuration in which a three-dimensional or plane mark is provided in the section having the same rank as the stacking order of the sub-housings among the sections in the rank specifying section, or each sub section in the sections in the rank specifying section It is good also as a structure which provided the solid | solid or plane mark other than the said division of the order same as the lamination | stacking order of a housing.

  According to such a configuration, the stacking order of each sub-housing can be identified based on the position of the three-dimensional or flat mark in the rank specifying portion of each sub-housing, or the position of the section where the three-dimensional or flat mark is not provided, An error in the stacking order can be prevented.

  Further, when the sub-housings are stacked in the correct order, the three-dimensional or flat mark in each rank specifying part, or the section not provided with the solid or flat mark is arranged diagonally on the diagonal line of each stacked sub-housing, A pattern having a certain regularity is formed.

  For example, among the sections in the rank specifying section, the sections in the same rank as the stacking order of the sub-housings are colored, or the sub-housings are stacked in the sections in the rank specifying section. It is good also as a structure which gave the coloring other than the said division of the same order as a ranking.

  According to such a configuration, the stacking order of each sub-housing can be identified based on the position of the colored section in the rank specifying portion of each sub-housing or the position of the section not colored. An error in the housing stacking order can be prevented.

  In addition, when the sub-housings are stacked in the correct order, the sections that are colored or not colored at each rank specifying portion are arranged diagonally on the diagonal lines of the stacked sub-housings, and are constant as a whole. A pattern having regularity is formed.

  According to the splice absorbing connector of the present invention, when the splice absorbing connector is assembled, the sub housings are stacked in accordance with the three-dimensional mark (rank specifying portion) provided on one surface of each sub housing, thereby preventing the stacking order from being mistaken. It can be prevented.

  When the sub-housings are stacked in the correct order, the individual rank specifying portions of the sub-housings form a pattern having a certain regularity as a whole, so that correct / incorrect determination is easy.

  In particular, since the order specifying portion is configured so that the same number of three-dimensional marks as the stacking order are provided in parallel at equal intervals on the one surface of each sub-housing, one surface of each sub-housing is assembled when the splice absorbing connector is assembled. By stacking the sub-housings in accordance with the rank specifying part (corresponding to the number of three-dimensional marks and the stacking order, etc.) provided in the above, an error in the stacking order can be prevented.

  In addition, when the sub-housings are stacked in the correct order, the order specifying portions of these sub-housings form a pattern having a certain regularity as a whole. It is possible to instantaneously determine whether the error is correct and what is wrong in the stacking order.

  According to the stacking order correctness determination apparatus of the present invention, when the inspection tool main body is advanced to the side of each sub-housing, only the detection pin that is in contact with the three-dimensional mark of each rank specifying portion is retracted, and the switch is pushed down. Based on the operation of each switch, the correctness of the stacking order of each sub-housing can be easily determined.

  According to the stacking order correctness determination method of the present invention, when the inspection tool main body is moved forward to each sub-housing side using the correctness determination apparatus, only the detection pins that are in contact with the three-dimensional marks of the respective rank specifying portions are retracted. Then, it is possible to easily and reliably determine whether or not the stacking order of the sub-housings is correct based on the operation of each switch at this time.

  The splice absorbing connector of the present invention is an improvement of the above-described splice absorbing connector shown in FIG. 10. In the embodiment described below, the same reference numerals are used for the same parts as the splice absorbing connector shown in FIG. Detailed description will be omitted.

  1 and 2A, the splice absorbing connector 1 of this embodiment includes six sub-housings 20A, 20B, 20C, 20D, 20E, and 20F, and as shown in FIG. When the sub-housings 20A to 20F are stacked in order, the terminals (not shown) of the sub-housings in each stage are normally connected. The sub-housings 20A to 20F are each provided with a rank specifying portion 40 on a common surface (front surface in the case of this embodiment) 20a.

  The rank specifying part 40 has a different appearance position for each of the sub-housings 20A to 20F, and means a predetermined stacking order of the sub-housings 20A to 20F.

  In the present embodiment, the order specifying unit 40 is configured so that one surface 20a of each of the sub-housings 20A to 20F is conceptually the same as the number of stacked stages (six stages), that is, 40a, 40b, 40c, 40d, 40e, and 40f. Of these sections 40a to 40f, in addition to the sections having the same order as the stacking order of the sub-housings 20A to 20F, convex solid marks 41, 41, 41, 41, 41 are provided.

  In other words, only the sections 40a to 40f having the same order as the stacking order of the sub-housings 20A to 20F do not have the solid mark 41, thereby meaning the stacking order of the sub-housings 20A to 20F.

  For example, in the rank specifying part 40 of the first stage sub-housing 20A, the solid mark 41 is not provided in the first section 40a, and in the rank specifying part 40 of the second stage sub-housing 20B, the second section 40b is not provided. The solid mark 41 is not provided.

  According to the splice absorbing connector 1 of the present embodiment having such a configuration, each sub-housing is based on the positions of the sections 40a to 40f where the three-dimensional mark 41 is not provided in the rank specifying portion 40 of each sub-housing 20A to 20F. The stacking order of 20A to 20F can be identified, and an error in the stacking order of the sub-housings 20A to 20F can be prevented.

  Further, as shown in FIG. 2A, when the sub-housings 20A to 20F are stacked in the correct order, the sections 41a to 41f that are not provided with the three-dimensional marks 41 in the respective rank specifying portions 40 become the stacked sub-housings 20A. A pattern having a certain regularity as a whole is formed so as to be diagonally arranged on a diagonal line of ˜20F.

  On the other hand, as shown in FIG. 2B, if the stacking order of the sub-housings 20A to 20F is wrong, the sections 40a to 40f that are not provided with the three-dimensional marks 41 in the rank specifying portions 40 are not regularly arranged, and it is uncomfortable. Feel the irregular pattern.

  Therefore, the operator can visually check such a three-dimensional shape pattern and sense the presence or absence of a certain regularity, and whether or not the stacking order of each of the sub-housings 20A to 20F is correct and how. You can instantly determine whether you are wrong.

  However, in the present invention, the correctness of the stacking order of the sub-housings 20A to 20F is determined by the correctness determination device. This correctness determination apparatus is based on the inspection tool 90 shown in FIG.

  In the figure, an inspection tool 90 has an inspection tool body 91 that can be moved forward and backward with respect to the stacked sub-housings 20A to 20F.

  Inside the inspection tool main body 91, it is possible to advance and retreat corresponding to all the sections 40a to 40f (6 × 6 = 36 sections, see FIG. 2A) of the order specifying part 40 of each sub-housing 20A to 20F. Detection pins 92 are accommodated.

  Further, behind each detection pin 92, a switch 93... For individually detecting the advance / retreat of each detection pin 92 is attached.

  According to such an inspection tool 90, when the inspection tool main body 91 is advanced to the sub housings 20 </ b> A to 20 </ b> F by operating the lever 94, only the detection pin 92 that is in contact with the three-dimensional mark 41 of each rank specifying unit 40. Retreat and press switch 93. Based on the operation of each switch 93 at this time, the correctness of the stacking order of the sub-housings 20A to 20F can be determined.

  Next, a splice absorbing connector according to a second embodiment of the present invention will be described with reference to FIGS. 4 (a) and 4 (b).

  4A and 4B are front views of the sub-housings constituting the splice absorbing connector according to the second embodiment of the present invention.

  4A, in the present embodiment, only the sections 40a to 40f having the same rank as the stacking order of the sub-housings 20A to 20F in the rank specifying unit 40 are provided with the solid marks 41, so that the sub-housings 20A to 20F are provided. The stacking order of each is given meaning. In other words, the configuration of the order specifying unit 40 has a reverse relationship to that of the first embodiment described above.

  According to the above configuration, the stacking order of the sub-housings 20A to 20F can be identified based on the position of the solid mark 41 in the rank specifying unit 40 of each of the sub-housings 20A to 20F, and the stacking order of the sub-housings 20A to 20F can be identified. Errors can be prevented beforehand.

  Further, as shown in FIG. 4A, when the sub-housings 20A to 20F are stacked in the correct order, the three-dimensional marks 41 in the rank specifying portions 40 are diagonally inclined on the diagonal lines of the stacked sub-housings 20A to 20F. A pattern having a certain regularity as a whole is formed side by side.

  On the other hand, as shown in FIG. 4B, if the stacking order of the sub-housings 20A to 20F is wrong, the three-dimensional marks 41 in the rank specifying portions 40 are not regularly arranged, and an irregular pattern that feels uncomfortable is formed. To do.

  By determining the presence or absence of regularity of such a three-dimensional shape pattern by visual inspection or the like, as in the first embodiment, the correctness of the stacking order of each of the sub-housings 20A to 20F, and where and how of the stacking order is determined. You can instantly determine whether you are wrong.

  According to such a configuration, the stacking order of the sub-housings 20A to 20F can be identified based on the number of the three-dimensional marks 41 in the rank specifying unit 40 of the sub-housings 20A to 20F, and the stacking of the sub-housings 20A to 20F can be identified. An order error can be prevented.

  Further, as shown in FIG. 5A, when the sub-housings 20A to 20F are stacked in the correct order, the three-dimensional marks 41 of the rank specifying portions 40 as a whole increase by one for each of the sub-housings 20A to 20F. A three-dimensional shape pattern having a certain regularity is formed.

  On the other hand, as shown in FIG. 5B, if the stacking order of the sub-housings 20A to 20F is wrong, the regularity of the entire three-dimensional mark 41 is lost, and an irregular pattern that feels uncomfortable is formed.

  The presence or absence of regularity of such a three-dimensional shape pattern can also be determined by visual observation or the like. Like in the first embodiment, whether or not the stacking order of each of the sub-housings 20A to 20F is correct and what is in the stacking order.
