[0023] [Description of Embodiments of the Invention]
[0024] First, embodiments of the present invention will be described by way of example.
[0025] The connector of the present invention,
[0026] (1) A device comprising a housing, terminal parts, and a stop body, wherein the housing has multiple cavities, a first locking receiving portion corresponding to one of the cavities, and a second locking receiving portion corresponding to the other cavities, the terminal parts being disposed in the cavities, and the stop body being disposed in the housing to restrict the terminal parts from disengaging from the cavities. Furthermore, the stop body comprises a flexible sheet capable of bending and deforming, the flexible sheet comprising: a first locking portion for locking the first locking receiving portion; a second locking portion for locking the second locking receiving portion; and a slit disposed between the first locking portion and the second locking portion. The slit opens in the disengagement direction in which the stop body disengages from the housing. According to this structure, when releasing the locking of the first locking portion and the first locking receiving portion or the locking of the second locking portion and the second locking receiving portion, a release jig can be inserted from the opening into the slit to perform a release operation. The slit effectively separates the region with the first locking portion and the region with the second locking portion in the flexural piece, allowing each region to flex smoothly. Thus, according to the present invention, the slit that allows the flexural piece to flex smoothly can be used as an insertion path for a release fixture, thereby enabling the release operation of the stop body without complicating the structure.
[0027] (2) Preferably, the stop body has a groove that is continuous with the slit in the disengagement direction, the groove being disposed between a pair of walls extending parallel to the disengagement direction. According to this structure, a release fixture can be inserted into the groove between the pair of walls, and the pair of walls are used as guides for guiding the release fixture. As a result, the insertion of the release fixture can be performed more easily and efficiently.
[0028] (3) Preferably, the flexible sheet has end slits at its ends in the width direction orthogonal to the release direction and on both sides of the first locking portion and the second locking portion, and the opening width of the slits is larger than the opening width of the end slits. With this structure, since the regions of the flexible sheet having the first locking portion and the regions having the second locking portion are arranged between the end slits, each region can be flexed and deformed more smoothly. Furthermore, if the release jig is inserted into the slit with the large opening width, the strength of the release jig is easily ensured.
[0029] (4) Preferably, the stop body has a stepped portion at the position adjacent to the flexible piece, and the slit extends from the opposing surface of the stepped portion on the flexible piece side to the opposite surface. According to this structure, by inserting the release jig into the slit and rotating it, and with the front end of the release jig abutting against the opposing surface of the stepped portion, the release jig is moved in the disengagement direction, thereby releasing the locking of the first locking portion and the first locking receiving portion, or the locking of the second locking portion and the second locking receiving portion. Since the release jig does not contact the locking structures of the first locking portion, the first locking receiving portion, the second locking portion, and the second locking receiving portion, damage to the locking structures can be avoided. Furthermore, it is possible to prevent the tip of the jig from damaging the sealing surface of the housing.
[0030] [Detailed Embodiments of the Invention]
[0031] The following description, with reference to the accompanying drawings, illustrates specific examples of the connector of the present invention. Furthermore, the present invention is not limited to these examples, but is intended to include all modifications within the meaning and scope equivalent to the claims, as indicated by the claims.
[0032] <Example 1>
[0033] like Figure 1 As shown, the connector of Embodiment 1 includes: a housing 10; a plurality of terminal parts 50 housed in the housing 10; and a stop 60 that is movable relative to the housing 10 between a temporary locking position and a permanent locking position. The housing 10 is positioned from the front ( Figure 1 (The left side) is fitted into the other shell 90.
[0034] (Opponent's shell)
[0035] like Figure 1 As shown, the counterpart housing 90 is made of synthetic resin and is inserted into the cover portion 11 (described later) and the fitting cylinder portion 62 of the housing 10. The counterpart housing 90 houses a counterpart terminal part (not shown) that can be connected to the terminal part 50. An annular sealing member 95 is fitted onto the outer peripheral surface of the counterpart housing 90. When the two housings 10 and 90 are fitted together, the sealing member 95 is compressed and sandwiched between the cover portion 11 and the counterpart housing 90. Thus, a liquid-tight seal is formed between the two housings 10 and 90.
[0036] (case)
[0037] like Figures 5-7 As shown, the housing 10 is made of synthetic resin and includes: a housing body 12; a cover portion 11 protruding forward from the outer periphery of the housing body 12; and a mounting portion 13 protruding below the housing body 12 and the cover portion 11. A bracket (not shown) is mounted on the mounting portion 13. A sealing member 95, mounted on the opposite housing 90, is in close contact with the inner peripheral surface of the cover portion 11.
[0038] The housing body 12 has multiple cavities 14. Each cavity 14 extends through the housing body 12 in the front-to-back direction and in the width direction ( Figure 6 as well as Figure 7 The terminals 50 are arranged in pairs (in the left and right directions). Terminal parts 50 are inserted into each cavity 14 from the rear of each cavity 14.
[0039] like Figure 5 as well as Figure 7 As shown, the housing body 12 has a rearwardly protruding sealing tower portion 15 at its rear. The rear portions of each cavity 14 are arranged side by side in the width direction inside the sealing tower portion 15.
[0040] like Figure 7 As shown, the rear portion of each cavity 14 within the sealing tower portion 15 has a longitudinally elongated oval (including elliptical) cross-sectional shape (opening shape). Since the diameter dimension in the width direction of the rear portion of each cavity 14 is smaller than the diameter dimension in the vertical direction, the housing 10 is prevented from becoming large in the width direction.
[0041] The vertical diameter of the rear portion of each cavity 14 is larger than the vertical diameter of the front portion of each cavity 14. For example... Figure 1 As shown, rubber plugs 55, which are connected to terminal parts 50, are inserted into the rear of each cavity 14. The rubber plugs 55 are tightly attached to the inner circumferential surface of the sealing tower part 15, thus liquid-tightly sealing the inside of the housing body 12.
[0042] like Figure 5 as well as Figure 6 As shown, the housing body 12 has a cavity tower 16 protruding forward within the cover 11 at its front portion. The front portions of each cavity 14 are arranged in the width direction within the cavity tower 16. The housing body 12 has spear-shaped members 17 protruding into each cavity 14 on the upper wall of the cavity tower 16. Figure 1 As shown, the spear-shaped member 17 locks the terminal part 50 at its front end in the protruding direction, thereby preventing the terminal part 50 from disengaging from the cavity 14.
[0043] The housing body 12 has locking grooves 18 on the lower inner surface (lower inner wall surface) of each cavity 14. For example... Figure 3 as well as Figure 7 As shown, the locking groove 18 extends in the front-rear direction, and its rear end opens on the lower rear surface of the cavity 14 within the sealing tower portion 15.
[0044] like Figure 5 As shown, the front portion of the locking groove 18 penetrates the lower wall of the cavity tower 16 in the thickness direction (vertical direction). The housing body 12 has a first locking receiving portion 21 and a second locking receiving portion 22 on the lower wall of the cavity tower 16, which close the front ends of each locking groove 18. The first locking receiving portion 21 and the cavity tower 14 located in the cavity tower 16 are connected to the lower wall of the cavity tower 16. Figure 3The upper cavity 14 (one cavity 14) is correspondingly provided. The second locking receiving part 22 is located in each cavity 14. Figure 3 The lower cavity 14 (other cavities 14) is correspondingly provided. The first locking receiving part 21 locks with the first locking part 73 described later, and the movement of the stop body 60 is restricted from the formal locking position to the temporary locking position (see Figure 3 The second locking receiving part 22 engages with the second locking part 74 described later, and the limiting stop 60 disengages forward from the temporary locking position (see...). Figure 4 ).
[0045] The first locking receiving part 21 and the second locking receiving part 22 are inclined surfaces that slope backward and upward, forming across the entire height of the lower wall of the cavity tower part 16 in the vertical direction (thickness direction) (see...). Figure 5 The first locking receiving part 21 and the second locking receiving part 22 are respectively disposed at the same position in the front-rear direction or at positions close to each other in the front-rear direction. Figure 7 As shown, the first locking receiving part 21 and the second locking receiving part 22 are rectangular on the back side.
[0046] The housing body 12 has a first abutment 23 and a second abutment 24 at the lower part of the opening edge of each cavity 14 on the front surface of the cavity tower 16. For example... Figure 1 As shown, the first blocking part 23 is positioned in front of the first locking receiving part 21. The second blocking part 24 is positioned in front of the second locking receiving part 22. The first blocking part 23 blocks the first locking part 73, thereby restricting the movement of the stop body 60 from the temporary locking position to the permanent locking position (see...). Figure 4 The second blocking part 24 blocks the second locking part 74, thereby temporarily restricting the stop body 60 from reaching the temporary locking position.
[0047] The first abutment 23 and the second abutment 24 are inclined surfaces that slope downwards and backwards, and are formed at the lower part of the front surface of the cavity tower 16 at an inner end that is recessed compared to the surrounding area (see...). Figure 5 The first abutment 23 and the second abutment 24 are respectively positioned at the same location in the front-rear direction or at locations close to each other in the front-rear direction. For example... Figure 6 As shown, the first blocking part 23 and the second blocking part 24 are rectangular from the front.
[0048] (Terminal components)
[0049] Terminal part 50 is made of conductive metal and is formed into an elongated shape in the front-to-back direction by bending a metal plate. For example... Figure 1As shown, the terminal part 50 is a male terminal and has a protruding tab 51 that protrudes forward. The tab 51 is configured to protrude into the cover 11. The terminal part 50 has a cylindrical part 52 at its rear end for crimping connection with the wire 40 and the rubber plug 55. Furthermore, the terminal part 50 has a cylindrical body part 53 between the tab 51 and the cylindrical part 52. The front end of the spear-shaped member 17 enters and is locked into the opening in the upper wall of the body part 53.
[0050] (stop body)
[0051] like Figure 5 , Figure 8 as well as Figure 9 As shown, the stop body 60 is made of synthetic resin, is cylindrical in shape, and is open in the front-to-back direction. The stop body 60 has an insertion cylindrical portion 61 at the rear and a fitting cylindrical portion 62 at the front. The vertical diameter of the fitting cylindrical portion 62 is larger than the vertical diameter of the insertion cylindrical portion 61.
[0052] The stop body 60 has a step portion 63 in the vertical direction between the front end of the insertion cylinder portion 61 and the rear end of the fitting cylinder portion 62. Figure 2 as well as Figure 9 As shown, the rear surface of the step portion 63 is a counter surface 64 that faces the latch portion 82 of the release jig 80 described later when the stop body 60 is disassembled, and is configured to be flat in both the vertical and width directions. The front surface of the step portion 63 is a counter surface 65 facing the opposite side of the counter surface 64, and is similarly configured to be flat in both the vertical and width directions.
[0053] like Figure 1 As shown, the insertion cylinder 61 is inserted into the insertion space 66 formed between the cover 11 and the cavity tower 16. The fitting cylinder 62 is fitted into the cover 11.
[0054] The insertion tube portion 61 has a limiting portion 67 on its upper wall. For example... Figure 5 As shown, when the stop 60 is in the temporary locked position, the limiting part 67 is configured to retract forward relative to the deflection space 68 of the spear-shaped member 17 within the insertion space 66, allowing the deflection of the spear-shaped member 17. On the other hand, as Figure 1 As shown, when the stop body 60 is in the fully locked position, the rear end of the limiting part 67 enters the flexural space 68, limiting the flexural action of the spear-shaped member 17.
[0055] The lower wall of the insertion cylinder 61 is configured as a flexible, flat plate 71 capable of bending and deforming. For example... Figure 5 As shown, the flexible sheet 71 is thinner than the restrictive portion 67. For example... Figure 9As shown, the flexible sheet 71 has a slot-shaped slit 72 extending in the front-to-back direction at its central portion in the width direction. The slit 72 passes through the flexible sheet 71 in the thickness direction (vertical direction). The rear end of the slit 72 closes in a semi-circular arc shape at the rear of the flexible sheet 71.
[0056] Additionally, the slit 72 extends from the flexural plate 71 to the step portion 63. For example... Figure 8 As shown, the front end of the slit 72 opens on the opposite side 65 of the step portion 63. That is, the slit 72 opens in front of the stop 60 (in the direction in which the stop 60 detaches from the housing 10). The slit 72 opens into a longitudinally elongated rectangle on the opposite side 65 of the step portion 63. In addition, the slit 72 extends through the lower part of the step portion 63 in a front-back direction and also opens on the opposite side 64 of the step portion 63.
[0057] like Figure 9 As shown, the flexible sheet 71 has a first locking portion 73 and a second locking portion 74 on both sides of the slit 72 in the width direction. The second locking portion 74 is located at the rear end of the flexible sheet 71, further rearward than the first locking portion 73. The second locking portion 74 is positioned to overlap with the slit 72 in the front-rear direction and has a portion positioned further rearward than the slit 72. The first locking portion 73 is located at the center of the flexible sheet 71 in the front-rear direction. The first locking portion 73 is positioned to completely overlap with the slit 72 in the front-rear direction. Both the first locking portion 73 and the second locking portion 74 are trapezoidal blocks with inclined front and rear surfaces. The inclination angle (inclination angle relative to the front-rear direction) of the front surface of the second locking portion 74 is larger than the inclination angle of the rear surface of the first locking portion 73. The inclination angle of the rear surface of the second locking portion 74 is smaller than the inclination angle of the rear surface of the first locking portion 73.
[0058] like Figure 9 As shown, the flexible sheet 71 has end slits 75 at both ends in the width direction. Each end slit 75 is positioned in the flexible sheet 71 on the opposite side of the slit 72, separated by the first locking portion 73, and on the opposite side of the slit 72, separated by the second locking portion 74. In other words, the first locking portion 73, the second locking portion 74, and the slit 72 are positioned in the flexible sheet 71 inside the width direction of each end slit 75.
[0059] Each end slit 75 extends through the flexible sheet 71 in the thickness direction (vertical direction). The rear end of each end slit 75 closes in a semi-circular arc shape at the rear of the flexible sheet 71. Each end slit 75 extends from the flexible sheet 71 to the stepped portion 63. The front end of each end slit 75 opens on the opposite side 65 of the stepped portion 63. Figure 8As shown, each end slit 75 opens into a longitudinally elongated rectangle on the opposite side 65 of the step portion 63. The opening height (depth in the vertical direction) of each end slit 75 of the step portion 63 is smaller than the opening height of the slit 72 of the step portion 63. Furthermore, the opening width of each end slit 75 is smaller than the opening width of the slit 72. The slits 72 and each end slit 75 reduce the rigidity of the flexural piece 71, allowing for flexural movement of the flexural piece 71.
[0060] like Figure 8 as well as Figure 9 As shown, the fitting cylindrical portion 62 has a pair of wall portions 76 at its bottom, which is connected to the flexural plate 71 and the stepped portion 63. Each wall portion 76 is provided as a rib protruding from both sides of the upper surface of the bottom wall in the width direction. Each wall portion 76 extends parallel to each other in the front-rear direction, with its front end facing the front surface of the opening of the stop body 60, and its rear end connected to the stepped portion 63. The groove 77 formed between the wall portions 76 communicates with the slit 72 on the opposite side 65 of the stepped portion 63.
[0061] (Methods for assembling and disassembling the stop body)
[0062] The stop 60 is inserted into the cover 11 from the front. At this time, the insertion action of the stop 60 is guided by the sliding of the fitting cylinder 62 on the inner peripheral surface of the cover 11. The insertion cylinder 61 is inserted into the insertion space 66 formed between the cavity tower 16 and the cover 11, and the flexural piece 71 is arranged along the lower surface side of the cavity tower 16.
[0063] When the stop 60 is about to reach the temporary locking position, the rear surface of the second locking part 74 slides against the second abutting part 24, and the flexural piece 71 flexes downward with the step part 63 as the fulcrum. When the stop 60 reaches the temporary locking position, the flexural piece 71 elastically recovers, as... Figure 4 As shown, the second locking part 74 is embedded. Figure 4 The second locking portion 74 is positioned opposite the second locking receiving portion 22 and is capable of locking in the lower locking groove 18. Furthermore, when the stop body 60 reaches the temporary locking position, the first locking portion 73 is positioned opposite the first abutting portion 23 and is capable of locking in the lower locking position. Thus, the stop body 60 is positioned in the temporary locking position in a state where its movement relative to the housing 10 in the forward and backward directions is restricted.
[0064] With the stop 60 in a temporary locked position, the terminal parts 50 are inserted into the cavities 14 of the housing body 12. When the terminal parts 50 are properly inserted into the cavities 14, the front end of the spear-shaped member 17 engages with the opening of the main body 53 and is locked in place. Thus, the terminal parts 50 are held relative to the housing 10 in a first-level anti-disengagement state.
[0065] Next, the stop 60 moves from the temporary locking position to the final locking position. When a thrust is applied to the stop 60 toward the final locking position, the first locking part 73 slides against the first abutment part 23, the locking state between the first locking part 73 and the first abutment part 23 is released, and the flexural piece 71 flexes downward about the step 63 side as a fulcrum. When the stop 60 reaches the final locking position, the flexural piece 71 elastically recovers, as... Figure 3 As shown, the first locking part 73 is embedded in Figure 3 The first locking part 73 is configured to face the first locking receiving part 21 and be able to lock in the upper locking groove 18. At this time, the second locking part 74 is configured in the locking groove 18 to exit from the second locking receiving part 22. Since the first locking part 73 locks the first locking receiving part 21, the movement of the stop body 60 in the direction of returning to the temporary locking position is restricted.
[0066] Additionally, when the stop body 60 reaches the final locking position, such as Figure 1 As shown, the rear end of the limiting part 67 enters the flexural space 68, while the terminal part 50 is held in a secondary anti-dislodgement state relative to the housing 10. In addition, the rear end of the insertion cylinder part 61 of the stop 60 abuts against the inner end of the insertion space 66, thereby restricting the movement of the stop 60 rearward from the normal locking position.
[0067] Considering maintenance and other factors, when the terminal part 50 is pulled out of the housing 10, the stop 60 returns from the normal locking position to the temporary locking position. At this time, using... Figure 3 The release jig 80 shown includes a jig body 81. The jig body 81 is a rod-shaped component extending slenderly in the front-to-back direction. The diameter of the jig body 81 is smaller than the opening width of the slot 77 and the opening width of the slit 72, but larger than the opening width of each end slit 75. A latching portion 82 is bent and provided at the rear end of the jig body 81.
[0068] The jig body 81 is inserted from the front into the groove 77 of the fitting cylinder portion 62, guided by the wall portions 76 and further inserted into the slit 72. With the rear portion of the jig body 81 inserted into the slit 72, the jig body 81 rotates about its axial direction. Thus, as... Figure 2 as well as Figure 3As shown, the latching part 82 is configured to face the opposing surface 64 of the step part 63. In this state, the jig body 81 moves forward. The latching part 82 is latched onto the opposing surface 64 of the step part 63 and locked, applying a forward release force to the stop body 60. Furthermore, when the jig body 81 moves forward, the front surface of the first locking part 73 slides on the first locking receiving part 21, and the flexural piece 71 flexes downward about the step part 63 side. When the first locking part 73 reaches the front surface side of the cavity tower part 16, the flexural piece 71 elastically recovers, and the stop body 60 can return to the temporary locking position.
[0069] With the stop body 60 in a temporarily locked position, the spear-shaped member 17 can be bent by another terminal removal tool (not shown) and pulled backward while holding the wire 40, so that the terminal part 50 can be pulled out from the cavity 14 of the housing 10.
[0070] If the movement of the jig body 81 forward continues, the second locking part 74 passes over the second locking receiving part 22 and reaches the front surface side of the cavity tower part 16, which can cause the stop body 60 to disengage from the housing 10 forward.
[0071] As explained above, according to Embodiment 1, the slit 72 is disposed between the first locking portion 73 and the second locking portion 74 in the flexible plate 71, opening towards the front of the stop body 60 (the disengagement direction in which the stop body 60 disengages from the housing 10). Therefore, by inserting the jig body 81 of the release jig 80 into the slit 72 from the front of the stop body 60, the locking state (temporary locking state and permanent locking state) of the stop body 60 relative to the housing 10 can be released. Since the slit 72 has both the function of flexing and deforming the flexible plate 71 and the function of releasing the release jig 80, the structure of the stop body 60 is not complicated.
[0072] Furthermore, since the latching portion 82 of the release fixture 80 does not contact the inner circumferential surface of the cover portion 11, damage to the inner circumferential surface of the cover portion 11 can be avoided. Therefore, the sealing member 95 can fit snugly against the inner circumferential surface of the cover portion 11, thereby maintaining a tight seal.
[0073] Furthermore, the stop 60 has a groove 77 that is continuous with the slit 72. Since the groove 77 is positioned between a pair of wall portions 76, the fixture body 81 of the release fixture 80 can be inserted into the groove 77, and each wall portion 76 is used as a guide to guide the fixture body 81. As a result, the insertion operation of the release fixture 80 can be performed more easily and effectively.
[0074] Furthermore, since the flexible plate 71 has end slits 75 on both sides in the width direction separated by the first locking portion 73 and the second locking portion 74, and the opening width of the slit 72 is larger than the opening width of the end slits 75, it is easy to ensure the strength of the fixture body 81 of the release fixture 80.
[0075] Furthermore, since the stop 60 has a stepped portion 63 adjacent to the flexible piece 71, and the slit 72 extends from the opposite surface 64 of the stepped portion 63 to the opposite surface 65, by engaging the latching portion 82 of the fixture body 81 with the opposite surface 64 of the stepped portion 63 and moving the fixture body 81 forward, the locking state of the first locking portion 73 and the first locking receiving portion 21, as well as the locking state of the second locking portion 74 and the second locking receiving portion 22, can be released. In this way, the release fixture 80 can be positioned so as not to contact the locking structures such as the first locking portion 73, the first locking receiving portion 21, the second locking portion 74, and the second locking receiving portion 22, thereby preventing damage to the locking structures. Additionally, it is possible to prevent the top of the release fixture 80 from damaging the sealing surface of the housing 10 (the inner peripheral surface of the cover portion 11 to which the sealing member 95 is in close contact).
[0076] [Other embodiments of the present invention]
[0077] The embodiments disclosed herein are illustrative in all respects and are not intended to limit.
[0078] In the case of Embodiment 1, a first locking part and a first locking receiving part are provided as a formal locking structure to restrict the stop body from moving from the formal locking position to the temporary locking position, and a second locking part and a second locking receiving part are provided as a temporary locking structure to restrict the stop body from moving forward from the temporary locking position. However, in other embodiments, the stop body may not have a temporary locking structure, and the first locking part, the first locking receiving part, the second locking part, and the second locking receiving part may all be components that form the formal locking structure.
[0079] In the case of Embodiment 1, the rear end of the slit is closed at the rear of the flexure sheet; however, in other embodiments, the rear end of the slit may be open at the rear end of the flexure sheet.
[0080] In the case of Embodiment 1, the stop body is fitted into the sleeve portion within the cover portion; however, in other embodiments, the stop body may not have the sleeve portion.
