Description

Connector guide structure

[0001] The present disclosure relates to a guide structure for a connector.

[0002] For example, when mounting a module component on a vehicle body, it is necessary to mate a module-side connector with a vehicle-side connector to establish an electrical connection. One such connector is described in Japanese Patent Laid-Open Publication No. 2005-183033 (Patent Document 1). This connector includes a receptacle connector and a plug connector, and the receptacle connector has a plug connector mating portion into which the plug connector mates.

[0003] Japanese Patent Application Laid-Open No. 2005-183033

[0004] In the above-mentioned connector, when the receptacle connector and the plug connector are mated, the housing of the plug connector comes into contact with the plug connector mating portion, so there is a risk that the housing may be damaged by the impact of assembly, preventing a smooth mating operation.

[0005] The present disclosure was completed in light of the above circumstances, and an object of the present disclosure is to achieve a smooth mating operation without damaging the housing due to assembly shock.

[0006] The guide structure of the connector disclosed herein comprises a first housing having a pair of guide pins formed therein and a second housing having a pair of guide recesses formed therein, and the pair of guide pins are received in the pair of guide recesses so that the first housing and the second housing are guided into a correct mating position and mated together, and each of the pair of guide pins is split in half when viewed from the mating direction, and each of the pair of guide pins has a central axis extending in the mating direction, a split surface extending in the mating direction along the central axis, and a guide surface that slopes away from the central axis as it extends rearward in the mating direction, and the pair of guide pins are arranged so that the pair of guide surfaces protrude forward in the mating direction further than the first housing and the pair of split surfaces face inward, and the pair of guide recesses are arranged to protrude forward in the mating direction further than the second housing.

[0007] According to the present disclosure, the housing is not damaged by the shock during assembly, and a smooth mating operation of the connector can be achieved.

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be described. [1] A guide structure for a connector according to the present disclosure includes a first housing having a pair of guide pins formed therein and a second housing having a pair of guide recesses formed therein, the pair of guide pins being received in the pair of guide recesses to guide the first housing and the second housing into a correct mating position and to be mated, the pair of guide pins each having a split shape when viewed from the mating direction, each of the pair of guide pins having a central axis extending in the mating direction, a split surface extending in the mating direction along the central axis, and a guide surface inclined so as to move away from the central axis toward the rear in the mating direction, the pair of guide pins being arranged so that the pair of guide surfaces protrude forward in the mating direction beyond the first housing and the pair of split surfaces face inward, and the pair of guide recesses are arranged to protrude forward in the mating direction beyond the second housing.

[0010] Because the guide pins are split, the overall structure can be made smaller in the direction in which the paired guide pins are aligned compared to when the guide pins are not split. In the case of a guide pin that is not split (i.e., a guide pin whose guide surface is formed around the entire circumference), the portion that actually performs the guide function is only a portion (e.g., half) of the guide surface, and the guide function is not lost even if the guide pin is split in half.

[0011] When the first and second housings are fitted together and assembled, the guide pins and guide recesses come into contact before the housings come into contact with each other, preventing the housings from being damaged by the impact of assembly. Furthermore, the guide surfaces slide against the guide recesses, guiding the first and second housings into the correct fitting position and allowing for a smooth fitting operation.

[0012] [2] It is preferable that the pair of guide pins are formed integrally with the first housing, and the pair of guide recesses are formed integrally with the second housing. This allows the strength of the guide pins to be increased compared to when the pair of guide pins are formed separately from the first housing. Also, the strength of the guide recesses can be increased compared to when the pair of guide pins are formed separately from the second housing.

[0013] [3] It is preferable that the outer edge of the guide surface has a semicircular shape when viewed from the fitting direction.

[0014] [4] It is preferable that the outer edge of the guide surface has a semi-elliptical shape when viewed from the fitting direction.

[0015] [Details of the Embodiments of the Present Disclosure] The following describes embodiments of the present disclosure. The present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims. In the drawings, for the convenience of explanation, some components may be exaggerated or simplified. Furthermore, the dimensional ratios of each part may differ between drawings. In this specification, "orthogonal" does not only refer to a strict orthogonal relationship, but also includes a roughly orthogonal relationship within the scope of the operation and effect of this embodiment.

[0016] In addition, "facing" in this specification refers to surfaces or components facing each other, and includes not only cases where they are completely facing each other, but also cases where they are partially facing each other. In addition, "facing" in this specification includes both cases where a component separate from the two components is interposed between the two components, and cases where nothing is interposed between the two components.

[0017] First Embodiment A first embodiment of the present disclosure will be described with reference to Figures 1 to 8. In the following description, the direction indicated by arrow Z is the upward direction, the direction indicated by arrow X is the mating direction, and the direction indicated by arrow Y is the leftward direction. Note that for multiple identical components, only some of the components may be designated by reference numerals, and the reference numerals for other components may be omitted. Furthermore, the front-to-rear direction coincides with the mating direction of each connector, and the mating surface side of each connector is the forward side in the mating direction, and may also be simply referred to as the forward side.

[0018] (Connector guide structure 10) The connector guide structure 10 of this embodiment includes a male connector 20, a female connector 30, and a seal ring 40 (see FIG. 3). For example, the male connector 20 is assembled to a modular component, and the female connector 30 is assembled to a mating member such as a vehicle body. Therefore, by assembling the modular component to the mating member, the male connector 20 is mated with the female connector 30, thereby forming the connector guide structure 10.

[0019] (Male Connector 20) The male connector 20 is configured to include a male housing 21 made of synthetic resin and male terminals 22. The male housing 21 includes a hood portion 23 that opens forward and a pair of guide pins 24. As shown in Figure 5, the male terminals 22 include needle-shaped terminals that are elongated in the front-rear direction and flat tab-shaped terminals that are elongated in the front-rear direction. The male terminals 22 are held in the male housing 21 in a form that penetrates the rear wall 23A of the hood portion 23 in the front-rear direction.

[0020] As shown in FIG. 8 , the guide pin 24 has a half-shape, which is a circle split in half when viewed from the mating direction, and is formed integrally with the hood portion 23. The circle here refers to a circle centered on the central axis 25. The half-shape does not necessarily have to have a central angle of 180° strictly; for example, the central angle may be within a range of 90° to 270°. Furthermore, the term "pair of guide pins 24" refers to at least one pair of guide pins, but may also refer to three or more guide pins. For example, the male housing 21 may have one pair of guide pins and one additional guide pin, or may have multiple pairs of guide pins.

[0021] 1, the guide pin 24 has a pin body 24A that extends like a column and has a semicircular shape when viewed from the mating direction, and a semiconical guide portion 24B that decreases in diameter from the tip of the pin body 24A toward the front in the mating direction. As shown in FIG. 5, the inside of the guide pin 24 is hollow and opens rearward in the mating direction.

[0022] The guide pin 24 has a central axis 25 extending in the mating direction. The inner surface of the guide pin 24 facing the hood portion 23 is defined as a split surface 26. The split surface 26 extends in the mating direction along the central axis 25. Note that the split surface 26 does not necessarily have to include the central axis 25, as long as it extends in the mating direction along the central axis 25. For example, the split surface 26 may extend parallel to the central axis 25 at a position away from the central axis 25 when viewed in the mating direction. The split surface 26 is formed across the guide portion 24B and the tip end of the pin body 24A connected to the guide portion 24B. The pair of guide pins 24 are arranged so that the pair of split surfaces 26 face inward and face each other. The split surface 26 is formed to be flush with the inner circumferential surface of the hood portion 23.

[0023] The guide portion 24B has a guide surface 27 that is inclined so as to move away from the central axis 25 toward the rear in the fitting direction. As shown in Figure 8, the outer edge of the guide surface 27 when viewed from the fitting direction is semicircular. The pair of guide pins 24 are arranged so that the pair of guide surfaces 27 protrude forward in the fitting direction beyond the tip of the hood portion 23.

[0024] (Female Connector 30) The female connector 30 is configured to include a female housing 31 made of synthetic resin and female terminals (not shown). The female housing 31 includes an outer tubular portion 32 that fits onto the outside of the hood portion 23, a fitting portion 33 that fits onto the inside of the hood portion 23, and a pair of guide recesses 34. The female terminals are rectangular cylindrical terminals into which the male terminals 22 can be fitted. A plurality of cavities 33A are formed inside the fitting portion 33. The female terminals are held in the female housing 31 while being accommodated in the cavities 33A.

[0025] The guide recess 34 has a half-circle shape when viewed from the mating direction, and is formed integrally with the female housing 31. As shown in Figure 5, the interior of the guide recess 34 is hollow, and is open to the front and rear in the mating direction. In other words, the guide recess 34 has a shape that penetrates in the mating direction.

[0026] As shown in Fig. 4, the inner peripheral surface 34A of the guide recess 34 is formed in a semicircular shape along the outer peripheral surface of the pin body 24A. The pair of guide recesses 34 are arranged so that a portion of the pair of inner peripheral surfaces 34A protrudes forward in the mating direction beyond the tip of the mating portion 33. The pair of guide recesses 34 are arranged so that the pair of inner peripheral surfaces 34A face inward. When the male connector 20 and the female connector 30 are properly mated, as shown in Fig. 2, the tip of the guide pin 24 is arranged to pass through the guide recess 34 and protrude rearward in the mating direction.

[0027] As shown in Figure 3, a seal ring 40 is attached to the outer peripheral surface of the mating portion 33. When the pin bodies 24A of the pair of guide pins 24 are received in the pair of guide recesses 34, the male housing 21 and the female housing 31 are positioned in a correct mating position. Therefore, the seal ring 40 is evenly compressed over its entire circumference between the outer peripheral surface of the mating portion 33 and the inner peripheral surface of the hood portion 23. This keeps the interior of the mating portion 33 sealed from the outside.

[0028] 5, when the male connector 20 and the female connector 30 are mated and assembled, the guide pin 24 comes into contact with the guide recess 34 before the hood portion 23 of the male housing 21 comes into contact with the mating portion 33 of the female housing 31. Therefore, damage to the male housing 21 and the female housing 31 due to an impact during assembly can be prevented.

[0029] 6, the guide surface 27 slides against the inner peripheral surface 34A of the guide recess 34, guiding the male connector 20 and the female connector 30 into the correct mating position, thereby achieving a smooth guiding operation. Thereafter, as shown in FIG. 7, when the male connector 20 and the female connector 30 reach the correct mating position, the outer peripheral surface of the pin body 24A slides against the inner peripheral surface 34A of the guide recess 34, allowing the male connector 20 and the female connector 30 to continue mating while maintaining the correct mating position. Therefore, a smooth mating operation of the male connector 20 and the female connector 30 can be achieved.

[0030] (Effects of Embodiment 1) The connector guide structure 10 of Embodiment 1 includes a male housing 21 having a pair of guide pins 24 formed therein, and a female housing 31 having a pair of guide recesses 34 formed therein. The pair of guide pins 24 are received in the pair of guide recesses 34, thereby guiding the male housing 21 and the female housing 31 into a correct mating position and allowing them to mate together. Each of the pair of guide pins 24 is split in half when viewed from the mating direction. Each of the pair of guide pins 24 has a central axis 25 extending in the mating direction, a split surface 26 extending in the mating direction along the central axis 25, and a guide surface 27 that is inclined so as to move away from the central axis 25 toward the rear in the mating direction. The pair of guide pins 24 are arranged so that the pair of guide surfaces 27 protrude further forward in the mating direction than the male housing 21 and the pair of split surfaces 26 face inward, and the pair of guide recesses 34 protrude further forward in the mating direction than the female housing 31.

[0031] Because the guide pins 24 are split in half, the overall structure can be made smaller in the direction in which the paired guide pins are aligned, compared to when the guide pins are not split in half. For example, in the case of a guide pin whose guide surface is formed around its entire circumference, only half of the guide surface actually performs its guiding function, and so even if the guide pins are split in half, the guiding function is not lost.

[0032] When the male housing 21 and the female housing 31 are mated and assembled, the guide pin 24 and the guide recess 34 come into contact before the housings come into contact with each other, preventing the housings from being damaged by the impact of assembly. Also, the guide surface 27 slides against the guide recess 34, guiding the male housing 21 and the female housing 31 into the correct mating position and mating, achieving a smooth mating operation.

[0033] It is preferable that the pair of guide pins 24 are formed integrally with the male housing 21, and the pair of guide recesses 34 are formed integrally with the female housing 31. In this way, the strength of the guide pins 24 can be increased compared to when the pair of guide pins 24 are formed separately from the male housing 21. Also, the strength of the guide recesses 34 can be increased compared to when the pair of guide recesses 34 are formed separately from the female housing 31.

[0034] Second Embodiment A second embodiment of the present disclosure will be described with reference to Figures 9 and 10. A connector guide structure 210 according to the second embodiment is obtained by modifying the shapes of the guide pin 24 and the guide recess 34 of the first embodiment. Therefore, the same configurations and effects as those of the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

[0035] (Guide Structure 210 of Connector) The guide structure 210 of the connector of this embodiment includes a male connector 220, a female connector 230, and a seal ring 40.

[0036] (Male Connector 220) The male connector 220 is configured to include a male housing 221 made of synthetic resin and male terminals 22. The male housing 221 includes a hood portion 23 that opens forward, and a pair of guide pins 224.

[0037] As shown in Figure 10, the guide pin 224 has a half-shaped configuration, obtained by splitting an ellipse in half when viewed from the mating direction, and is formed integrally with the hood portion 23. The "ellipse" here refers to an ellipse centered on a central axis 225. The half-shaped configuration does not necessarily have to have a central angle of 180° strictly; for example, the central angle may be within a range of 90° to 270°. Furthermore, a pair of guide pins 224 means at least one pair of guide pins, and may be three or more guide pins.

[0038] 9, the guide pin 224 has a pin body 224A that is semi-elliptical and extends like a column when viewed from the mating direction, and a guide portion 224B whose diameter decreases from the tip of the pin body 224A toward the front in the mating direction. The inside of the guide portion 224B is hollow, similar to the guide portion 24B, and opens rearward in the mating direction.

[0039] The guide pin 224 has a central axis 225 extending in the fitting direction. The inner surface of the outer surface of the guide pin 224 facing the hood portion 23 is formed as a split surface 226. The split surface 226 extends in the fitting direction along the central axis 225. The split surface 226 is formed across the guide portion 224B and the tip end portion of the pin main body 224A connected to the guide portion 224B. The pair of guide pins 224 are arranged so that the pair of split surfaces 226 face inward and face each other. The split surface 226 is formed so as to be flush with the inner circumferential surface of the hood portion 23.

[0040] The guide portion 224B has a guide surface 227 that is inclined so as to move away from the central axis 225 toward the rear in the fitting direction. As shown in Figure 10, the outer edge of the guide surface 227 when viewed from the fitting direction is semi-elliptical. The pair of guide pins 224 are arranged so that the pair of guide surfaces 227 protrude forward in the fitting direction beyond the tip of the hood portion 23.

[0041] (Female Connector 230) The female connector 230 is configured to include a female housing 231 made of synthetic resin and female terminals (not shown). The female housing 231 includes an outer tubular portion 232 that fits onto the outside of the hood portion 23, a fitting portion 33 that fits onto the inside of the hood portion 23, and a pair of guide recesses 234. A plurality of cavities 33A are formed inside the fitting portion 33. The female terminals are held in the female housing 231 while being accommodated in the cavities 33A.

[0042] The guide recess 234 has a shape similar to a split ellipse when viewed from the mating direction, and is formed integrally with the female housing 231. The interior of the guide recess 234 is hollow, and is open to the front and rear in the mating direction. In other words, the guide recess 234 is formed to penetrate in the mating direction.

[0043] The inner peripheral surface 234A of the guide recess 234 is formed in a semi-elliptical shape along the outer peripheral surface of the pin body 224A. The pair of guide recesses 234 are arranged so that a portion of the pair of inner peripheral surfaces 234A protrudes forward in the mating direction beyond the tip of the mating portion 33. The pair of guide recesses 234 are arranged so that the pair of inner peripheral surfaces 234A face inward. When the male connector 220 and the female connector 230 are properly mated, the tip of the guide pin 224 is arranged to pass through the guide recess 234 and protrude rearward in the mating direction.

[0044] A seal ring 40 is attached to the outer peripheral surface of the mating portion 33. When the pin bodies 224A of the pair of guide pins 224 are received in the pair of guide recesses 234, the male housing 221 and the female housing 231 are positioned in a correct mating position. Therefore, the seal ring 40 is evenly compressed over its entire circumference between the outer peripheral surface of the mating portion 33 and the inner peripheral surface of the hood portion 23. This keeps the interior of the mating portion 33 sealed from the outside.

[0045] (Embodiment 3) Embodiment 3 of the present disclosure will be described with reference to Figures 11 and 12. A connector guide structure 310 according to embodiment 3 reverses the arrangement of the guide pins 24 and the guide recesses 34 in the connector guide structure 10 of embodiment 1. Therefore, the same configurations and effects as those of embodiment 1 will be denoted by the same reference numerals, and description thereof will be omitted.

[0046] (Guide Structure 310 of Connector) The guide structure 310 of the connector of this embodiment includes a female connector 320, a male connector 330, and a seal ring 40.

[0047] (Female Connector 320, Male Connector 330) The male connector 330 is configured to include a male housing 331 made of synthetic resin and male terminals 22. The male housing 331 includes a hood portion 23 that opens forward and a pair of guide recesses 334.

[0048] The female connector 320 is configured to include a female housing 321 made of synthetic resin and female terminals (not shown). The female housing 321 includes a fitting portion 33 that fits into the inside of the hood portion 23, and a pair of guide pins 324. A plurality of cavities 33A are formed inside the fitting portion 33. The female terminals are held in the female housing 321 while being accommodated in the cavities 33A.

[0049] (Guide pin 324, guide recess 334) As shown in Fig. 12, the guide pin 324 has a half-shape obtained by splitting a circle in half when viewed from the fitting direction, and is formed integrally with the fitting portion 33. The circle referred to here refers to a circle centered on the central axis 325. Furthermore, the half-shape does not necessarily have to have a central angle of 180° strictly; for example, the central angle may be within a range of 90° to 270°. Furthermore, a pair of guide pins 324 means at least one pair of guide pins, and may be three or more guide pins.

[0050] 11, the guide pin 324 has a pin body 324A that extends like a semicircular column when viewed from the mating direction, and a guide portion 324B that decreases in diameter from the tip of the pin body 324A toward the front in the mating direction. The inside of the guide portion 324B is hollow, similar to the guide portion 24B, and opens rearward in the mating direction.

[0051] The guide pin 324 has a central axis 325 extending in the mating direction. The inner surface of the outer surface of the guide pin 324 facing the mating portion 33 is formed as a split surface 326. The split surface 326 extends in the mating direction along the central axis 325. The split surface 326 is formed across the guide portion 324B and the tip and both side portions of the pin main body 324A connected to the guide portion 324B. The pair of guide pins 324 are arranged so that the pair of split surfaces 326 face inward and face each other.

[0052] The guide portion 324B has a guide surface 327 that is inclined so as to move away from the central axis 325 toward the rear in the fitting direction. As shown in Figure 12, the outer edge of the guide surface 327 when viewed from the fitting direction is semicircular. The pair of guide pins 324 are arranged so that the pair of guide surfaces 327 protrude forward in the fitting direction beyond the tip of the fitting portion 33.

[0053] The inner peripheral surface 334A of the guide recess 334 is formed in a semicircular shape along the outer peripheral surface of the pin body 324A. The pair of guide recesses 334 are arranged so that a portion of the pair of inner peripheral surfaces 334A protrudes forward in the mating direction beyond the tip of the hood portion 23. The pair of guide recesses 334 are arranged so that the pair of inner peripheral surfaces 334A face inward. When the female connector 320 and the male connector 330 are properly mated, the tip of the guide pin 324 is arranged to pass through the guide recess 334 and protrude rearward in the mating direction.

[0054] A seal ring 40 is attached to the outer peripheral surface of the fitting portion 33. When the pin bodies 324A of the pair of guide pins 324 are received in the pair of guide recesses 334, the female housing 321 and the male housing 331 are positioned in a correct fitting position. Therefore, the seal ring 40 is evenly crushed over its entire circumference between the outer peripheral surface of the fitting portion 33 and the inner peripheral surface of the hood portion 23. This keeps the interior of the fitting portion 33 sealed from the outside.

[0055] (Other Embodiments) The above-described first to third embodiments can be modified and implemented as follows: The above-described first to third embodiments can be implemented in combination with each other within the scope of technical compatibility.
