Description

Technical Field

[0001] This disclosure relates to connectors. Background Technology

[0002] Patent Document 1 discloses a connector comprising a first housing and a second housing that can be fitted together, a locking arm disposed in the first housing, and a first terminal housed in the first housing. The locking arm locks the second housing, holding the first and second housings in a fitted state. When the first and second housings are properly fitted, the first terminal, which is linked to the locking arm, connects to the second terminal of the second housing. This allows for the detection of the proper fit between the first and second housings.

[0003] In the case of Patent Document 1, no waterproof structure is provided around the first and second terminals. Therefore, the reliability of the detection of mating may be lacking. In contrast, Patent Documents 2 to 5 disclose a technique in which a waterproof structure is provided around terminals used for detecting mating, such as the first and second terminals.

[0011] The problem that the invention aims to solve

[0012] However, rod-type connectors are known to guide the connector to a mating state based on the rotation of the rod. In this case, the following consideration is made: the probe part for mating, which is linked to the rod, is mated with the counterpart probe part to achieve waterproofing between the probe parts. However, the action of mating the probe part with the counterpart probe part to achieve waterproofing becomes a linear movement parallel to the mating direction, which is sometimes difficult to coordinate with the rotation of the rod.

[0013] Therefore, the present disclosure aims to provide a waterproof connector that enables the detection part to be linked with the rod.

[0014] Solution for solving the problem

[0015] The connector disclosed herein comprises: a connector body capable of engaging with a counterpart connector body; a rod rotatably supported on the connector body, which, in the engaging position, causes the connector body and the counterpart connector body to engage properly; a detection part separate from the connector body, which engages with the counterpart detection part when the rod is in the engaging position; and a detection-side sealing part liquid-tightly disposed between the detection part and the counterpart detection part, wherein the detection part and the rod have a motion conversion part that contacts each other and converts the rotational motion of the rod into a linear movement motion of the detection part relative to the counterpart detection part.

[0016] Invention Effects

[0017] According to this disclosure, a waterproof connector can be provided that enables a probe to move with a rod. Attached Figure Description

[0026] [Description of embodiments of this disclosure]

[0027] First, the implementation methods of this disclosure are listed and explained.

[0028] The connector disclosed herein,

[0029] (1) It comprises: a connector body capable of engaging with a counterpart connector body; a rod rotatably supported on the connector body, which properly engages the connector body and the counterpart connector body in the engaging position; a detection part separate from the connector body, which engages with the counterpart detection part when the rod is in the engaging position; and a detection-side sealing part liquid-tightly disposed between the detection part and the counterpart detection part, wherein the detection part and the rod have an action conversion part that contacts each other and converts the rotational movement of the rod into a linear movement of the detection part relative to the counterpart detection part.

[0030] When the rod is in the engaged position, the probe engages with the counterpart probe. Therefore, by electrically or mechanically detecting this state, it can be determined that the connector body and the counterpart connector body are in a properly engaged state. The connector uses a probe-side sealing part to make both the probe and the counterpart probe waterproof. Because the motion conversion part converts the rotational motion of the rod into a linear movement of the probe relative to the counterpart probe, the probe can engage well with the counterpart probe.

[0031] (2) Preferably, the action conversion unit has: a pressing part disposed on the rod; and a contact surface disposed on the detection part, which is pressed by the pressing part toward the opposite detection part. Accordingly, action conversion can be achieved through the simple structure of the pressing part and the contact surface.

[0032] (3) Preferably, a body-side sealing portion is provided, which is independent of the probe-side sealing portion and is liquid-tightly disposed between the connector body and the counterpart connector body. Accordingly, the connector body and the counterpart connector body are liquid-tightly sealed through the body-side sealing portion. Because the probe-side sealing portion and the body-side sealing portion are disposed around the probe portion and the connector body respectively, overall waterproofing of the connector can be achieved.

[0033] [Details of the embodiments of this disclosure]

[0034] The following is a reference to the appendix. Figure 1 Specific examples of this disclosure will be described below. Furthermore, the 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.

[0035] like Figure 1 As shown, the connector 10 of this embodiment includes a connector body 20, a body-side sealing portion 50, a probe portion 60, a probe-side sealing portion 80, and a rod 90. The connector body 20 and the probe portion 60 are separate from each other, but are connected by the rod 90 in a manner that allows for relative displacement. The connector body 20 and the probe portion 60 can be engaged with the other connector 100.

[0036] Additionally, in the following description, the front-to-back direction corresponds to the mating direction of connector 10 and the counterpart connector 100. The front side is the side of connector 10 and the counterpart connector 100 facing each other at the start of mating. The up-down direction excludes... Figure 2 and Figure 3 The vertical direction of all other figures is the reference point. The horizontal direction is... Figure 1 The paper thickness direction is Figure 2 The vertical direction. The vertical direction is synonymous with the height direction, and the horizontal direction is synonymous with the width direction. Figures 5-8 In the diagram, the front side is designated "X", the left side viewed from the front is designated "Y", and the top side is designated "Z". These directions are for illustrative purposes only and do not limit the orientation during assembly or use. Furthermore, structures with low relevance to the content of this disclosure are omitted or simplified in the figures.

[0037] <Partner Connector>

[0038] like Figure 5 As shown, the counterpart connector 100 includes a counterpart connector body 120 and a counterpart detection part 160. The counterpart connector body 120 has a cylindrical cover 121. The cover 121 is open at the front. Figure 1 and Figure 4 As shown, a plurality of male-shaped female terminals 126 are provided protruding inside the cover portion 121.

[0039] like Figure 5 As shown, the connector body 120 has a back plate portion 122 that rises from the rear end of the upper surface of the cover portion 121, and a top plate portion 123 that protrudes forward from the upper end of the back plate portion 122. The top plate portion 123 is disposed opposite to the upper surface of the cover portion 121 at a distance in the vertical direction. The top plate portion 123 is located on one side in the left-right direction ( Figure 5 The right side) allows the keyhole 124 to pass through. Additionally, the top plate portion 123 is on the other side in the left-right direction ( Figure 5 A pin-shaped cam follower 125 protrudes from the left end of the cover portion 121. The top of the cam follower 125 faces the upper surface of the cover portion 121. A cam follower 125 is also provided on the lower surface of the cover portion 121, which is coaxially arranged with the cam follower 125 at a distance from it.

[0040] The detector 160 protrudes forward from the back panel 122. Furthermore, the detector 160 is positioned between the upper surface of the cover 121 and the top panel 123, on one side facing the lock hole 124 of the top panel 123 in a left-right direction. The detector 160 has a square-shaped detector body 161 that opens in the front. Figure 4 As shown, a pair of male-shaped detector terminals 162 are protruding inside the detector body 161.

[0041] Furthermore, the cover 121, back plate 122, top plate 123, and counterpart detection body 161 are made of synthetic resin, and as described above, they are continuously integrated. The counterpart terminal 126 and counterpart detection terminal 162 are made of conductive metal.

[0042] <Connector Body>

[0043] like Figure 6 As shown, the connector body 20 integrally includes a terminal housing portion 21 and a fitting sleeve portion 22 that surrounds the outer periphery of the terminal housing portion 21. Both the terminal housing portion 21 and the fitting sleeve portion 22 are made of synthetic resin. Figure 1 and Figure 4 As shown, the terminal housing 21 fits into the cover 121. The terminal housing 21 has multiple cavities 23 at positions corresponding to each of the opposing terminals 126. Terminal parts 24 are inserted from the rear into each cavity 23.

[0044] Terminal component 24 is made of conductive metal, such as Figure 1 As shown, it is formed in a shape extending in the front-to-back direction. Terminal part 24 has a cylindrical connecting portion 25 and an open cylindrical portion 26 disposed behind the connecting portion 25. A counterpart terminal 126 is inserted into the connecting portion 25. The counterpart terminal 126 contacts the elastic contact piece 27 within the connecting portion 25 and is electrically connected to the terminal part 24. The cylindrical portion 26 is connected to the end of the wire 200. A rubber plug 210 is embedded in the outer peripheral surface of the wire 200. The cylindrical portion 26 has a portion that presses against the rubber plug 210. The rubber plug 210 is liquid-tightly inserted into the cavity 23.

[0045] A front retainer 28 on the main body side is mounted on the terminal housing 21 from the front. The front retainer 28 on the main body side is formed into a cover shape and is configured to partially cover the front surface to the outer peripheral surface of the terminal housing 21. A main body side insertion hole 29 communicating with each cavity 23 is provided on the front wall of the front retainer 28 on the main body side. The counterpart terminal 126 is connected to the terminal part 24 when it is inserted through the main body side insertion hole 29.

[0046] like Figure 6 As shown, the fitting cylindrical portion 22 is formed into a square tube shape, and has a functional wall 31 on its upper wall above the terminal receiving portion 21. The functional wall 31 has a guide portion 32 for guiding the movement of the probe portion 60 and a support portion 33 for supporting the support rod 90. The functional wall 31 has a flat upper surface on which the arm portion 91 of the rod 90 (described later) can contact the ground.

[0047] The guide portion 32 is located on one side of the upper surface of the functional wall 31 in the width direction. Figure 6 The guide portion 32 is a groove with a concave cross-section, extending in the front-rear direction, with its front end opening on the front surface of the functional wall 31 and its rear end opening on the rear surface of the functional wall 31. The support portion 33 is located on the other side of the upper surface of the functional wall 31 in the width direction. Figure 6 The right end of the fitting cylinder 22 protrudes cylindrically. A support portion 33, coaxially arranged and spaced apart from the aforementioned support portion 33, protrudes from the lower surface of the lower wall of the fitting cylinder 22. Furthermore, a recessed groove 34 is provided on the lower wall of the fitting cylinder 22. The recessed groove 34 extends in the front-rear direction, and its front end opens on the front surface of the lower wall of the fitting cylinder 22.

[0048] <Main Body Side Sealing Section>

[0049] The main body side sealing part 50 is a rubber sealing ring. For example... Figure 1 and Figure 4 As shown, the main body side sealing portion 50 is fitted into the outer peripheral surface of the terminal receiving portion 21. With the terminal receiving portion 21 fitted into the cover portion 121, the main body side sealing portion 50 is in close contact with the inner peripheral surface of the cover portion 121. The peripheral wall of the main body side front retainer 28 is disposed opposite to the front end of the main body side sealing portion 50. This prevents the main body side sealing portion 50 from dislodging forward.

[0050] <Detection Department>

[0051] like Figure 7 As shown, the detection unit 60 integrally includes a mounting portion 61 and a cylindrical portion 62 surrounding the outer periphery of the mounting portion 61. The mounting portion 61 and the cylindrical portion 62 are made of synthetic resin. The detection terminal 63 is held in the mounting portion 61.

[0052] The probe terminal 63 is made of conductive metal and is also called a short-circuit terminal. The probe terminal 63 has a pair of contact pieces 64 at the front. Each contact piece 64 can be elastically deformed and is formed integrally with each other.

[0053] The mounting portion 61 has an outer peripheral surface with a rectangular cross-section extending in the front-rear direction. The cylindrical portion 62 also has a rectangular cross-section extending in the front-rear direction. The cylindrical portion 62 and the mounting portion 61 are connected by a base end portion 65 disposed between their respective rear ends. The base end portion 65 has an outer peripheral surface with a rectangular cross-section that is continuous with the cylindrical portion 62.

[0054] like Figure 1 As shown, a front retainer 66 on the detection side is mounted on the mounting portion 61 from the front. The front retainer 66 is formed in the shape of a cover and is configured to partially cover the front surface to the outer peripheral surface of the mounting portion 61. A detection side insertion hole 67 is provided on the front wall of the front retainer 66 at a position opposite to each contact piece 64. The opposite detection terminal 162 is connected to the detection terminal 63 when inserted into the detection side insertion hole 67.

[0055] like Figure 3 As shown, the cylindrical portion 62 is inserted into the guide portion 32. The two sides of the cylindrical portion 62 are arranged face-to-face with the two sides of the guide portion 32, allowing them to contact each other. The upper surface of the cylindrical portion 62 is continuously arranged with the upper surface of the functional wall 31 without any steps.

[0056] like Figure 7 As shown, a groove 68 is provided on the rear end side of the detection unit 60. The groove 68 is recessed into the upper surface of the base end portion 65. The groove 68 extends in the left-right direction and is closed at both ends near the two sides of the base end portion 65. The groove 68 has a contact surface 69 extending in the left-right direction on its rearward-facing front surface. The contact surface 69 is in contact with the rod 90 in a state where it is pressed by the pressing part 96 described later. The opposing detection body 161 is inserted between the mounting part 61 and the cylindrical part 62.

[0057] <Detector-side sealing section>

[0058] The detection-side sealing part 80 is a rubber sealing ring. For example... Figure 1 and Figure 4 As shown, the detection-side sealing part 80 is fitted onto the outer peripheral surface of the mounting part 61. With the opposing detection body 161 fitted into the cylindrical part 62, the detection-side sealing part 80 is in close contact with the inner peripheral surface of the opposing detection body 161. The peripheral wall of the detection-side front retainer 66 is disposed opposite to the front end of the detection-side sealing part 80. This prevents the detection-side sealing part 80 from dislodging forward.

[0059] <pole>

[0060] Rod 90 is made of synthetic resin. For example... Figure 8 As shown, the rod 90 is formed into a gate-shaped plate, having a pair of arms 91 and a connecting portion 92 connecting one end of each arm 91. Each arm 91 is arranged with the plate surface facing up and down and parallel to each other. The connecting portion 92 is shaped to extend in the up and down direction.

[0061] The upper arm 91 of each arm 91 is located on the side closest to the connecting portion 92 in the width direction. Figure 8 The right side of the arm 91 has a locking part 93. The locking part 93 is elastically deformable on one side of the arm 91 in the width direction and is located between a pair of slits 94 extending in the front-rear direction. A locking protrusion 95 is provided on the locking part 93 protruding upward. The locking protrusion 95 is inserted into and locked with the locking hole 124 of the other connector body 120.

[0062] Additionally, the upper arm 91 has a pressing part 96 near the locking part 93. The pressing part 96 protrudes downward from the mounting wall 97, which is provided between each slit 94, at the rear end of the arm 91 in a pin-like, or more specifically cylindrical, shape. The mounting wall 97 is located below the free end side (rear end side) of the locking part 93.

[0063] Each arm 91 places a pair of shaft holes 98 on the opposite side in the width direction. Figure 8The left end of the connector body 20 is penetrated. Each support portion 33 of the connector body 20 is embedded in each shaft hole 98. Each arm portion 91 has a pair of cam grooves 99 near the shaft hole 98 at the end on the other side in the width direction. The cam grooves 99 are recessed in the upper surface of each arm portion 91 and open at the other end of the arm portion 91.

[0064] <Connector assembly and fitting methods>

[0065] First, a main body-side sealing portion 50 is installed on the outer peripheral surface of the terminal storage portion 21, and a probe-side sealing portion 80 is further installed on the outer peripheral surface of the mounting portion 61. Next, a main body-side front retainer 28 is installed from the front of the terminal storage portion 21, and a probe-side front retainer 66 is further installed from the front of the mounting portion 61.

[0066] Furthermore, a probe 60 is inserted into the guide portion 32 of the connector body 20. Next, a rod 90 is installed in the connector body 20. After each arm 91 elastically deforms, each support portion 33 is inserted into the shaft hole 98 of each arm 91. Thus, the rod 90 is rotatably supported relative to the connector body 20 in the initial position and the mating position with the mating position of each shaft hole 98 and each support portion 33 as the center. Each arm 91 is arranged to cover the upper surface of the functional wall 31 and the lower surface of the lower wall of the mating cylinder portion 22 respectively. Furthermore, the pressing portion 96 of the upper arm 91 is inserted from above into the groove 68 of the probe 60. In addition, at an appropriate time, a terminal part 24 is inserted into the cavity 23 of the terminal receiving portion 21, and a probe terminal 63 is installed in the mounting portion 61. The terminal part 24 is pre-connected to the end of the wire 200.

[0067] When the lever reaches the initial position, as Figure 3 As shown, one end of each arm 91 is positioned to protrude laterally toward the rear of the connector body 20. The rear of the probe 60 also protrudes toward the rear of the connector body 20 by pressing the contact surface 69 of the groove 68 with the pressing part 96 of the rod 90. The pressing part 96 is located at the other end within the groove 68.

[0068] Starting from the state where connector 10 is aligned with the other connector 100, the terminal receiving portion 21 is fitted into the cover portion 121, and the other probe body 161 is fitted into the cylindrical portion 62. At this time, the upper arm 91 of the rod 90 is positioned on the lower side of the top plate portion 123, and the lower arm 91 of the rod 90 is positioned on the lower side of the lower surface of the cover portion 121. Figure 3As shown, the top end of the detector body 161 enters the guide portion 32. Furthermore, each cam follower 125 enters the entrance of each cam groove 99. The lower cam follower 125 is configured to pass through the retraction groove 34 and the cam groove 99. In this state, one end of each arm 91 is pushed forward, and the rod 90 rotates toward the engagement position. Thus, the cam follower 125 of the counterpart connector body 120 slides on the groove surface of the cam groove 99, performing the engagement action between the connector body 20 and the counterpart connector body 120.

[0069] During the rotation of rod 90, such as Figures 3 to 2 As shown, the pressing part 96 presses against the contact surface 69 of the groove 68 while shifting to one side within the groove 68. The detection part 60 is pressed by the pressing part 96 and thus shifted forward while being guided by the guide part 32. The opposing detection body 161 is inserted deeper into the cylindrical part 62 of the detection part 60. In this way, the rotational movement of the rod 90 is transformed into a linear forward and backward movement of the detection part 60 engaging with the opposing detection part 160. That is to say, the contact surface 69 of the groove 68, the pressing part 96, and the guide part 32 constitute a part that becomes an action transformation part.

[0070] When rod 90 reaches the engaged position, as Figure 1 As shown, the connector body 20 and the counterpart connector body 120 are properly engaged, and the terminal part 24 is connected to the counterpart terminal 126 in a normal state. The connector body 20 and the counterpart connector body 120 are liquid-tightly sealed by the body-side sealing part 50. In addition, when the rod 90 reaches the engaged position, the locking protrusion 95 of the locking part 93 is inserted into the locking hole 124, and the connector body 20 and the counterpart connector body 120 remain in the engaged state.

[0071] As the locking protrusion 95 of the locking part 93 inserts into the lock hole 124, the detection part 60 located near the locking part 93 also properly engages with the counterpart detection part 160. Simultaneously, each contact piece 64 of the detection terminal 63 contacts the counterpart detection terminal 162, closing the detection circuit. Thus, the detection rod 90 can be electrically brought to the engaged position, thereby ensuring that the connector body 20 and the counterpart connector body 120 are in a properly engaged state. Furthermore, the detection part 60 and the counterpart detection part 160 are liquid-tightly sealed by the detection-side sealing part 80.

[0072] When the connector 10 is disengaged, the rod 90 is rotated from the engaged position toward the initial position. Then, by pressing the rear surface of the groove 68, which is opposite to the contact surface 69, by the pressing part 96, the probe 60 is guided by the guide part 32 and moved backward to return to its original position.

[0073] As described above, according to this embodiment, when the rod 90 is in the engaged position, the detection unit 60 engages with the counterpart detection unit 160. Therefore, by electrically detecting this state, it can be determined that the connector body 20 and the counterpart connector body 120 are in a properly engaged state. Furthermore, the detection unit 60 and the counterpart detection unit 160 are liquid-tightly sealed by the detection-side sealing unit 80.

[0074] The contact surface 69 of the groove 68 and the pressing part 96, among other motion-changing parts, transform the rotational motion of the rod 90 into a linear movement of the probe 60 relative to the counterpart probe 160. Therefore, the probe 60 can fit well into the counterpart probe 160. In particular, the motion-changing mechanism is achieved through the simple structure of the pressing part 96 and the contact surface 69. Furthermore, the connector body 20 and the counterpart connector body 120 are also liquid-tightly sealed by the main body side sealing part 50, which is separate from the probe side sealing part 80. As a result, the connector 10 is waterproof overall.
