Description

[Technical Field]

[0001] The present invention relates to a case used in an electrical connector, a partition that divides the interior of the case, and an electrical connector. [Background technology]

[0002] The electric motor includes a motor-side electrical connector for receiving power and control signals, and a motor-side electrical connector for transmitting power and control signals is mated and connected to the motor-side electrical connector. The motor electrical connector includes a case, a housing accommodated in the case, and terminals held by the housing. The arrangement of the terminals held in the housing corresponds to the arrangement of the terminals of the mating motor-side connector. Furthermore, the motor electrical connector has wires drawn out, and the direction in which these wires are drawn out (drawing direction) varies depending on the environment in which the motor is used, etc.

[0003] Patent Document 1 describes an electrical connector in which the direction in which electric wires are drawn out can be selected as desired. As shown in Figure 17 of Patent Document 1, the electrical connector of Patent Document 1 is provided with a partition that divides the storage space of the case that houses the housing into a left space and a right space.

[0004] In the electrical connector of Patent Document 1, a power supply housing that holds power terminals is housed in the left space, and a signal housing that holds signal terminals is housed in the right space. The power supply housing and signal housing in Patent Document 1 have the same dimensions in the left-right direction. Therefore, the partition divides the storage space of the case that houses the housings symmetrically. In this case, the partition is provided at a fixed position in the left-right direction, i.e., the center of the arrangement direction of the housings.

[0005] However, for example, the dimensions of the power supply housing and the signal housing in the arrangement direction may differ. When two housings of different dimensions are accommodated in this manner, the housing space of the case is divided asymmetrically in the arrangement direction by a partition. In an electrical connector in which the housing space of the case is divided asymmetrically in this manner, for example, if the wire extraction directions are reversed, the positions of the power supply housing and the signal housing in the arrangement direction must be swapped accordingly. For example, if the power supply housing is placed in the right-side housing space and the signal housing is placed in the left-side housing space, the power supply housing may be placed on the left and the signal housing in the right-side housing space. In this case, the position of the partition must be changed to accommodate the difference in the left-right dimensions of the power supply housing and the signal housing, so two types of cases with different partition positions are required.

[0019] Hereinafter, an electrical connector 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings. The electrical connector 1 includes two housings, a first housing 10A and a second housing 10B, and a case 30. With the electrical connector 1, even if the direction in which the electric wires 200 are drawn out is changed (FIGS. 6 and 7), the storage space 32 that houses the first housing 10A and the second housing 10B can be partitioned asymmetrically by changing the position of the partition 50. In other words, the electrical connector 1 can accommodate changes in the arrangement of the first housing 10A and the second housing 10B while using one type of case 30. For ease of explanation, as shown in the drawings, the direction in which the housings 10 housed in the case 30 are lined up is referred to as a first direction X, the right side of the first direction X is referred to as (R), the left side is referred to as (L), the direction in which the electric wires are drawn out of the case 30 intersects with the first direction X is referred to as a second direction Y, the front side of the second direction Y is referred to as (F), the rear side is referred to as (B), the mating direction in which the electric connector 1 is mated with the mating connector 100 is referred to as a third direction Z, and the upper side of the third direction Z is referred to as (U) and the lower side is referred to as (D). In this embodiment, the first direction X and the second direction Y are perpendicular to each other. 5 to 7, the first direction X, the second direction Y, and the third direction Z are shown so that the directions after the electrical connector 1 and the mating connector 100 are the same after mating.

[0020] [Electrical connector 1: See Figures 1, 6, and 7] 1, the electrical connector 1 includes a first housing 10A and a second housing 10B in which terminals are held, and a case 30 in which the housing 10 is housed in a housing space 32. A partition 50 is attached to the case 30 to divide the housing space 32 into two sections. The electrical connector 1 is an electrical connector that is mated with a mating connector, for example, a motor-side connector.

[0021] [Case 30: See Figures 1 and 2] As shown in FIG. 1 , the case 30 is configured with a case body 31 that provides an accommodation space 32 for accommodating the housing 10. The first housing 10A and the second housing 10B are sometimes collectively referred to as the housing 10. The accommodation space 32 is a rectangular parallelepiped space surrounded by the case body 31, corresponding to the external shape of the housing 10. The accommodation space 32 accommodates the first housing 10A and the second housing 10B side by side. The case body 31 has a rectangular cylindrical shape and, facing the accommodation space 32, includes a front wall surface 31F, a first rear wall surface 31B1, a second rear wall surface 31B2, a third rear wall surface 31B3, a fourth rear wall surface 31B4, a first taper 31CA, a second taper 31CB, and an upper wall surface 31U. A bolt 37 is attached to the outer periphery of the case body 31 for fastening to the mating connector 100. The case body 31 is formed as a single member by injection molding an electrically insulating resin material.

[0022] 2, the accommodation space 32 is formed with a first accommodation space 32A on the right side in the first direction X, in the direction R, and a second accommodation space 32B on the left side in the first direction X, in the direction L. In other words, the first accommodation space 32A is formed on the left side of the paper in FIG. 2, and the second accommodation space 32B is formed on the right side of the paper. The dimensions of the first housing space 32A and the second housing space 32B in the first direction X differ depending on the position of the partition 50 to be attached in the first direction X. That is, the first housing space 32A may be larger than the second housing space 32B in this dimension, or the first housing space 32A may be smaller than the second housing space 32B in this dimension. Of the first housing space 32A and the second housing space 32B, the first housing 10A is disposed in the one with the larger dimension, and the second housing 10B is disposed in the one with the smaller dimension. In this way, the volumes of the first housing space 32A and the second housing space 32B change depending on the position of the partition 50.

[0023] A fitting groove 33 is formed in the center of the case body 31 in the first direction X as a partition member fixing portion that positions and fixes the partition 50. The fitting groove 33 is composed of a first fitting groove 33A provided on the right side in the first direction X, in the direction R, and a second fitting groove 33B provided on the left side in the first direction X, in the direction L. In other words, the first fitting groove 33A and the second fitting groove 33B serving as a plurality of partition member fixing portions are formed in the case body 31.

[0024] The first fitting groove 33A is provided at a position shifted from the center toward the right direction R, and the second fitting groove 33B is provided at a position shifted from the center toward the left direction L. The first fitting groove 33A and the second fitting groove 33B are provided at positions symmetrical with respect to the center and are parallel to each other. The first fitting groove 33A is formed to be continuous with the front wall surface 31F, the upper wall surface 31U, and the first rear wall surface 31B1, and has a C-shape. The second fitting groove 33B is also formed to be continuous with the front wall surface 31F, the upper wall surface 31U, and the first rear wall surface 31B1, and has a C-shape. The partition 50 is fixed to the case body 31 by fitting the insertion portion 57 of the partition 50 into the first fitting groove 33A and the second fitting groove 33B.

[0025] A central guide 34 is provided between the first fitting groove 33A and the second fitting groove 33B, a right guide 35A is provided to the right direction R of the first fitting groove 33A, and a left guide 35B is provided to the left direction L of the second fitting groove 33B.

[0026] The central guide 34 is formed to be continuous with the front wall surface 31F, the upper wall surface 31U, and the first rear wall surface 31B1, and protrudes toward the storage space 32, and has a C-shape. The protrusion amounts of the portion of the central guide 34 on the front wall surface 31F side and the portion on the first rear wall surface 31B1 side are greater than the protrusion amount of the central portion between the front wall surface 31F and the first rear wall surface 31B1. The right guide 35A and the left guide 35B have the same configuration.

[0027] The central guide 34 and the right guide 35A position and guide the insertion portion 57 of the partition 50 in the first direction X during the process of fitting the partition 50 into the first fitting groove 33A. The central guide 34 and the left guide 35B position and guide the insertion portion 57 of the partition 50 in the first direction X during the process of fitting the partition 50 into the second fitting groove 33B.

[0028] As shown in Figures 6 and 7, a first wire outlet tube 40A and a second wire outlet tube 40B are formed on the front F side of the case body 31 in the second direction Y, through which the electric wire 200 connected to the terminal of the housing 10 is inserted. That is, the first wire outlet tube 40A and the second wire outlet tube 40B specify the direction in which the electric wire 200 is drawn out of the case 30 and, ultimately, the electrical connector 1. That is, in this embodiment, there are cases in which the electric wire 200 is drawn out to the front F as shown in Figure 6 and cases in which the electric wire 200 is drawn out to the rear B as shown in Figure 7, but even if the drawing direction of the electric wire 200 is reversed, it is sufficient to prepare one type of case 30. The electric wire 200 is a general term for the power line 200A and the control line 200B.

[0029] The first wire drawing tube 40A is composed of an insertion tube 41A extending from the case body 31 toward the front F in the second direction Y, and a clamping nut 42A fastened to the insertion tube 41A. The second wire pull-out tube 40B is composed of an insertion tube 41B extending forward F in the second direction Y from the case body 31, and a clamping nut 42B fastened to the insertion tube 41B.

[0030] 6, the third rear wall surface 31B3 guides the positioning portion 17B of the second housing 10B and positions the second housing 10B in the second direction Y. In addition, in FIG. 7, the third rear wall surface 31B3 guides the positioning portion 17A of the first housing 10A and positions the first housing 10A in the second direction Y. 6, the fourth rear wall surface 31B4 guides the positioning portion 17A of the first housing 10A and positions the first housing 10A in the second direction Y. In addition, in FIG. 7, the fourth rear wall surface 31B4 guides the positioning portion 17B of the second housing 10B and positions the second housing 10B in the second direction Y.

[0031] The first taper 31CA guides the sloped surface 16B of the second housing 10B in Fig. 6, and guides the sloped surface 16A of the first housing 10A in Fig. 7. The second taper 31CB guides the sloped surface 16A of the first housing 10A in Fig. 6, and guides the sloped surface 16B of the second housing 10B in Fig. 7.

[0032] [Housing 10: See Figures 1, 6, and 7] 1, the two housings 10 have different functions: the first housing 10A holds terminals to which power lines 200A for power and braking are connected, and the second housing 10B holds terminals to which encoder control lines 200B are connected. Even if the direction in which the electric wires 200 are drawn is reversed, the connection relationship between the first housing 10A and the power lines 200A and the connection relationship between the second housing 10B and the control lines 200B remains unchanged. Both the first housing 10A and the second housing 10B are rectangular parallelepiped shaped. The first housing 10A and the second housing 10B have the same dimensions in the second direction Y and the third direction Z, but the first housing 10A is larger than the second housing 10B in the first direction X. Due to this difference in dimensions, the arrangement of the partition 50 is changed when the direction in which the electric wires 200 are drawn out is reversed. Each of the first housing 10A and the second housing 10B is formed as a single member by injection molding an electrically insulating resin material.

[0033] 6 and 7, the first housing 10A has a first key groove 11A and a second key groove 12A extending in the second direction Y, and a third key groove 13A extending in the first direction X, formed on its bottom surface. A side guide 14A that conforms to the shape of the partition 50 is formed on the side surface of the first housing 10A extending in the second direction Y. Sloped surfaces 16A that make it easier to insert the first housing 10A into the case 30 are formed on the four corners of the first housing 10A. In addition, positioning portions 17A that position the first housing 10A in the second direction Y on the third rear wall surface 31B3 or the fourth rear wall surface 31B4 of the case 30 are formed on both sides of the first housing 10A in the second direction Y. The first housing 10A also holds a plurality of terminals 21A to be connected to the power line 200A.

[0034] The second housing 10B is formed with a first key groove 11B extending in the first direction X. Sloped surfaces 16B that make it easier to insert the second housing 10B into the case 30 are formed at the four corners of the second housing 10B. Furthermore, positioning portions 17B that position the second housing 10B in the second direction Y on the third rear wall surface 31B3 or the fourth rear wall surface 31B4 of the case 30 are formed on both sides of the second housing 10B in the second direction Y. The second housing 10B also holds a plurality of terminals 21B that are connected to the control lines 200B.

[0035] [Partition 50: See Figures 1, 3, 4, 6, and 7] Divider 50 is attached to case 30 to ensure an insulating distance that electrically insulates first housing 10A and second housing 10B housed in case 30. Also, by ensuring an insulating distance between first housing 10A and second housing 10B, the influence of electromagnetic noise caused by current passing through terminal 21A held by first housing 10A on communication signals passing through terminal 21B held by second housing 10B can be reduced. As shown in Fig. 1, the partition 50 is attached to the case 30 and divides the accommodating space 32 into a first accommodating space 32A and a second accommodating space 32B. A first housing 10A and a second housing 10B are accommodated in the first accommodating space 32A and the second accommodating space 32B, respectively, which are divided by the partition 50. However, when the electric wire 200 is drawn forward F, the second housing 10B is disposed in the first accommodating space 32A, and the first housing 10A is disposed in the second accommodating space 32B. On the other hand, when the electric wire 200 is drawn backward B, the first housing 10A is disposed in the first accommodating space 32A, and the second housing 10B is disposed in the second accommodating space 32B.

[0036] The partition 50 that divides the storage space 32 is provided as a separate member from the case 30. The partition 50 is formed as a separate member from the case 30 by injection molding an electrically insulating resin material. The partition 50 is configured to be detachable from the fitting groove 33 of the case 30. Furthermore, when the electric wire 200 is drawn out from the front F, the partition 50 is disposed in the first fitting groove 33A, and when the electric wire 200 is drawn out from the rear B, the partition 50 is disposed in the second fitting groove 33B.

[0037] 3 and 4, the partition 50 is provided with a partition portion 51 that divides the storage space 32 of the case 30 into a first storage space 32A and a second storage space 32B. The partition portion 51 has a rectangular plate-like shape. When the first direction X is the thickness direction of the partition portion 51, the second direction Y is the longitudinal direction of the partition portion 51, and the third direction Z is the short-side direction of the partition portion 51, abutment portions 52 are formed on both sides of the partition portion 51 in the longitudinal direction.

[0038] The abutting portion 52 extends from the longitudinal end of the partitioning portion 51 toward both sides in the thickness direction. The length of the abutting portion 52 extending toward one side in the thickness direction is longer than the length of the abutting portion 52 extending toward the other side. The abutting portion 52 extends to a length that is more than approximately half the length of the partitioning portion 51 in the direction in which the partitioning portion 51 extends in the short side direction.

[0039] A first inclined surface portion 53 and a second inclined surface portion 54 are formed at the corner portion where the partition portion 51 and the abutting portion 52 are connected. The first inclined surface portion 53 forms an angle of approximately 45 degrees with the partition portion 51 when viewed in the short direction, and extends from the tip of the portion of the abutting portion 52 that extends toward the other side in the plate thickness direction toward the partition portion 51. The second inclined surface portion 54 is formed line-symmetrically with the first inclined surface portion 53, with the center of the plate thickness of the partition portion 51 in the plate thickness direction as the reference. The portion that extends beyond the second inclined surface portion 54 on one side in the plate thickness direction is called a longitudinal portion 55 of the abutting portion 52 .

[0040] Two side guides 56 are formed on both sides in the thickness direction of the partition section 51. The side guides 56 are formed at positions offset from the center in the longitudinal direction of the partition section 51 so as to protrude from the surfaces on both sides in the thickness direction of the partition section 51. The side guides 56 extend to the same length as the abutting sections 52 in the direction in which the abutting sections 52 extend in the short side direction.

[0041] An insertion portion 57 is provided at the end of the partition portion 51 opposite to the end where the abutment portion 52 is formed in the short side direction. The insertion portion 57 is positioned and guided in the first direction X by the central guide 34 and the right guide 35A of the case 30, or by the central guide 34 and the left guide 35B.

[0042] 2, when the partition 50 is inserted into the first fitting groove 33A, which is provided at a position shifted to the right direction R from the center of the case 30, the second accommodating space 32B on the right direction R side in the first direction X becomes narrower, and the first accommodating space 32A on the left direction L side becomes wider. In this case, as shown in FIG. 7, the second housing 10B is disposed in the second accommodating space 32B, and the first housing 10A is disposed in the first accommodating space 32A. In other words, the partition 50 asymmetrically divides the accommodating space 32 in the first direction X in which the first housing 10A and the second housing 10B are aligned, so that the accommodating space 32 is narrower on the right direction R side and wider on the left direction L side.

[0043] 2, when the partition 50 is inserted into the second fitting groove 33B, which is provided at a position shifted to the left (L) side from the center of the case 30, the second housing space 32B on the right (R) side in the first direction X becomes wider, and the first housing space 32A on the left (L) side becomes narrower. In this case, as shown in FIG. 6, the first housing 10A is disposed in the second housing space 32B, and the second housing 10B is disposed in the first housing space 32A. In other words, the partition 50 asymmetrically divides the housing space 32 in the first direction X in which the first housing 10A and the second housing 10B are aligned, so that the housing space 32 becomes wider on the right (R) side and narrower on the left (L) side. That is, the partitions 50 can be attached to the fitting grooves 33 provided at different positions in the first direction X of the case 30.

[0044] 6, when the partition 50 is fitted into the first fitting groove 33A, the abutment portions 52 formed on both longitudinal sides of the partition portion 51 abut against the front wall surface 31F and the second rear wall surface 31B2 of the case 30. The provision of the longitudinal portions 55 of the abutment portions 52 increases the dimensions at which the abutment portions 52 abut against the front wall surface 31F and the second rear wall surface 31B2 of the case 30, allowing the partition 50 to be stably attached to the case 30. The first inclined surface portion 53 serving as a guide guides the inclined surface portion 16B of the second housing 10B. The second inclined surface portion 54 also serves as a guide guides the inclined surface portion 16A of the first housing 10A. The side guide 56 guides the side guide 14A of the first housing 10A.

[0045] 7, when the partition 50 is fitted into the second fitting groove 33B, the contact portions 52 come into contact with the front wall surface 31F and the second rear wall surface 31B2 of the case 30. As in the case of FIG. 6, the first inclined surface 53 guides the inclined surface 16B of the second housing 10B, the second inclined surface 54 guides the inclined surface 16A of the first housing 10A, and the side guide 56 guides the side guide 14A of the first housing 10A.

[0046] [Mating connector 100: See Figure 5] As shown in Figure 5, the mating connector 100 includes a third housing 110A that mates with the first housing 10A, a fourth housing 110B that mates with the second housing 10B, and a motor side case 130 that accommodates the third housing 110A and the fourth housing 110B. Even if the direction in which the electric wires 200 are drawn out of the electric connector 1 relative to the mating connector 100 is reversed, the arrangement of the third housing 110A and the fourth housing 110B remains unchanged.

[0047] The third housing 110A is formed with a first key 111A and a second key 112A extending in the second direction Y, and a third key 113A extending in the first direction X. Specifically, when the third housing 110A is fitted to the first housing 10A, the first key 111A, the second key 112A, and the third key 113A are formed on a surface of the third housing 110A that faces the first housing 10A. Additionally, third housing 110A holds a plurality of terminals 120A that are electrically connected to a plurality of terminals 21A of first housing 10A.

[0048] The fourth housing 110B is formed with a first key 111B extending in the first direction X. Specifically, the first key 111B is formed on a surface of the fourth housing 110B that faces the second housing 10B when the fourth housing 110B is fitted to the second housing 10B. Furthermore, the fourth housing 110B holds a plurality of terminals 120B that are electrically connected to the plurality of terminals 21B of the second housing 10B.

[0049] The motor-side case 130 is provided with a first internal thread 137A and a second internal thread 137B that are fastened to the bolts 37 of the case 30. The first internal thread 137A is provided on the front F side of the motor-side case 130 in the second direction Y, and the second internal thread 137B is provided on the rear B side of the motor-side case 130 in the second direction Y.

[0050] When the electric wire 200 is pulled out toward the rear B side, the bolt 37 of the case 30 is fastened to the first female screw 137A. On the other hand, when the electric wire 200 is pulled out in the opposite direction, toward the front F side, the bolt 37 of the case 30 is fastened to the second female screw 137B. The first female screw 137A and the second female screw 137B are used depending on the direction in which the electric wire 200 is pulled out.

[0051] [Mating connector 100 and electrical connector 1: see Figures 5, 6, and 7] In a motor (not shown) provided with the mating connector 100, the electric wires 200 are pulled out either toward the front F or the rear B in the second direction Y. Because the mating connector 100 is fixed to the motor, the arrangement of the third housing 110A and the fourth housing 110B cannot be changed. Therefore, the arrangement of the first housing 10A and the second housing 10B in the electrical connector 1 is changed, but the position of the partition 50 disposed between the first housing 10A and the second housing 10B is changed corresponding to the direction in which the electric wires 200 are pulled out. Note that FIG. 6 shows an electric connector 1A in which the electric wires 200 are pulled out toward the front F, and FIG. 7 shows an electric connector 1B in which the electric wires 200 are pulled out toward the rear B.

[0052] In the electrical connector 1A of FIG. 6, the first housing 10A is disposed in the second accommodating space 32B on the right side R of the partition 50, and the second housing 10B is disposed in the first accommodating space 32A on the left side L of the partition 50. In addition, in the electrical connector 1B of FIG. 7, the second housing 10B is disposed in the second accommodating space 32B on the right side R of the partition 50, and the first housing 10A is disposed in the first accommodating space 32A on the left side L of the partition 50.

[0053] For example, when responding to a request to pull out the electric wire 200 to the forward F side in the second direction Y, the electric connector 1A of FIG. When the mating connector 100 is mated with the electrical connector 1A, the first key 111A, second key 112A, and third key 113A of the third housing 110A, which correspond to the first key groove 11A, second key groove 12A, and third key groove 13A of the first housing 10A, respectively, are mated.

[0054] The key groove of the first housing 10A is fitted with the key of the third housing 110A, and the first key 111B of the fourth housing 110B, which corresponds to the first key groove 11B of the second housing 10B, is fitted therewith.

[0055] When the key and key groove are mated, it can be confirmed that the electrical connector 1A and the mating connector 100 are properly mated. Furthermore, if the key and key groove are not mated, it can be seen that the electrical connector 1A and the mating connector 100 will not be mated. Therefore, incorrect mating of the electrical connector 1A and the mating connector 100 can be prevented. After the electrical connector 1A and the mating connector 100 are mated, the bolt 37 is fastened to the second female thread 137B.

[0056] 7 is mated with the mating connector 100 when it is required to pull out the electric wires toward the rear B side in the second direction Y. In FIG.

[0057] Similar to when the mating connector 100 is mated with the electrical connector 1A, when the mating connector 100 is mated with the electrical connector 1B, the first key 111A, second key 112A, and third key 113A of the third housing 110A, which correspond to the first key groove 11A, second key groove 12A, and third key groove 13A of the first housing 10A, respectively, are mated.

[0058] The key groove of the first housing 10A is fitted with the key of the third housing 110A, and the first key 111B of the fourth housing 110B, which corresponds to the first key groove 11B of the second housing 10B, is fitted therewith.

[0059] As in FIG. 6, by fitting the key and key groove, it is possible to prevent erroneous mating of the electrical connector 1B and the mating connector 100. After the electrical connector 1B and the mating connector 100 are mated, the bolt 37 is fastened to the first female thread 137A.

[0060] [Effects of the embodiment] [Effect 1] The electrical connector 1 comprises two housings, a first housing 10A and a second housing 10B, and a case 30 in which an accommodating space 32 for accommodating the housing 10 is asymmetrically divided by a partition 50 that can change the mating position to either the first mating groove 33A or the second mating groove 33B. For example, when the electric wire 200 is pulled out toward the front F of the mating connector 100, the electrical connector 1 accommodates this by inserting the partition 50 into the first mating groove 33A, as shown in Figure 6, accommodating the first housing 10A in the second accommodating space 32B on the right side of the paper, and accommodating the second housing 10B in the first accommodating space 32A on the left side of the paper in Figure 6. In addition, when the electric wire 200 is pulled out toward the rear B side of the mating connector 100, the electrical connector 1 accommodates this by inserting the partition 50 into the second mating groove 33B, as shown in Figure 7, accommodating the second housing 10B in the second accommodating space 32B on the right side of the paper, and accommodating the first housing 10A in the first accommodating space 32A on the left side of the paper in Figure 7. According to the electrical connector 1, even if the direction in which the electric wires 200 are drawn out is changed (FIGS. 6 and 7), by changing the position of the partitions 50 that asymmetrically divide the accommodation space that accommodates the housing, it is possible to accommodate changes in the arrangement of the accommodated housing 10 with one type of case 30. In other words, the electrical connector 1 allows the direction in which the electric wires 200 are drawn out to be selected.

[0061] In addition to the above, the configurations given in the above embodiments can be selected or changed as appropriate to other configurations without departing from the spirit of the present invention. [Explanation of symbols]
