Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a multi-wire hybrid waterproof connector with anti-bend pin clips. Background Technology

[0002] Current wire harness connector assemblies all include male and female connectors, which mate together. On one hand, during automotive assembly, terminal bending can easily occur during the mating of male and female connectors, leading to poor mating. This bending is difficult to detect during assembly, creating potential problems for subsequent testing. On the other hand, as vehicle functions increase, the number of connector circuits also increases. More connector pins result in a larger product size, and to ensure smooth mating, the positioning requirements for the pins also increase, especially when using small-gauge terminals, where pin bending and displacement are common. Additionally, waterproofing is required depending on the product's installation location. To ensure a good user experience for multi-wire mixed waterproof connectors, the product needs to meet sealing requirements and include terminal anti-bending pin clips to ensure proper connector mating.

[0003] Patent CN217387738U discloses a wire harness connector assembly, including a male connector, a female connector, and an anti-bend pin module. The male connector has a slot at its front and multiple male terminal holes at its rear. The anti-bend pin module is formed by an anti-bend pin module bottom wall and an anti-bend pin module side wall, and can slide back and forth within the slot. The anti-bend pin module bottom wall has multiple anti-bend pin module terminal holes. The female connector has a female connector body that can be inserted rearward into the slot and the anti-bend pin module. The female connector body has multiple female terminal holes. When the male connector and the female connector are mated, the bottom wall of the anti-bend pin module is located between the rear side of the female connector body and the bottom surface of the slot, and the side wall of the anti-bend pin module is located between the outer side of the female connector body and the side surface of the slot.

[0004] Although the connector assembly is equipped with an anti-bending pin module, the relative position of the anti-bending pin module and the terminal on the connector cannot be determined during connector assembly, resulting in poor anti-bending effect on the terminal and affecting the assembly efficiency of the connector. Summary of the Invention

[0005] This invention proposes a multi-wire hybrid waterproof connector with an anti-bend pin clip, which solves the problem of poor anti-bend pin effect during the assembly of waterproof connectors in the prior art.

[0006] The technical solution of this invention is implemented as follows: A multi-line hybrid waterproof connector with a bending-resistant pin clip, comprising a plug sheath assembly and a socket sheath assembly that are inserted into each other. The plug sheath assembly includes a plug sheath, and a bending-resistant pin clip is detachably connected to the plug sheath. The socket sheath assembly includes a socket sheath, and a PLR structure is detachably connected to the socket sheath. The bending-resistant pin clip is detachably connected to the PLR structure. When the connector is mated, the bending-resistant pin clip plays a role in protecting the plug terminals, ensuring the accurate position of the plug terminals, and avoiding problems such as bent pins and retraction during the mating process. In addition, the PLR structure is detachably connected to the bending-resistant pin clip and is linked with the bending-resistant pin clip. When the connector is separated, the PLR structure can move the bending-resistant pin clip from the assembled position to the pre-assembled position, ensuring the accurate position of the terminals when the connector is mated through the bending-resistant pin clip, and facilitating the reuse of the bending-resistant pin clip.

[0007] The plug sheath is provided with a plug terminal hole notch I, a plug terminal hole notch II, and a plug terminal hole notch III, and the bending-resistant pin clip is provided with a bending-resistant pin clip boss I and a bending-resistant pin clip boss II; when the bending-resistant pin clip is in the pre-assembled position, the plug terminal hole notch I cooperates with the bending-resistant pin clip boss I, and the plug terminal hole notch III cooperates with the bending-resistant pin clip boss II; when the bending-resistant pin clip is in the fully assembled position, the plug terminal hole notch II cooperates with the bending-resistant pin clip boss I. The cooperation between the plug terminal hole notch I and the bending-resistant pin clip boss I uses a straight surface and an inclined surface, which can prevent the bending-resistant pin clip from entering the final position when in the pre-assembled position, and can push the bending-resistant pin clip boss I over the plug terminal hole notch I to reach the final position when pressure is applied; the cooperation between the plug terminal hole notch III and the bending-resistant pin clip boss II uses two straight surfaces to cooperate with each other, which can prevent the bending-resistant pin clip from脱出 from the pre-assembled position.

[0008] The bending-resistant pin clip is provided with a terminal hole I and a terminal hole II, and a terminal I and a terminal II are inserted into the plug sheath. The terminal I cooperates with the terminal hole I, and the terminal II cooperates with the terminal hole II. When the bending-resistant pin clip is in the pre-assembled position, the head of the terminal I extends out of the terminal hole, and the head of the terminal II extends out of the terminal hole II. It can effectively protect the plug terminals, prevent the terminals from being bent, and ensure smooth mating with the socket.

[0009] The back of the bending-resistant pin clip is provided with a vertical structure, and the vertical structure and the terminal hole of the plug sheath cooperate to form a square cavity; the bending-resistant pin clip is provided with a repair hole I and a repair hole II, and the repair hole I corresponds to the position of the terminal hole I, and the repair hole II corresponds to the position of the terminal hole II. The square cavity limits and fixes the terminals, ensuring the stable installation of the terminals in the terminal holes and preventing the terminals from shaking; when the bending-resistant pin clip is in the pre-assembled position, an unlocking tool can be used to pass through the repair hole to unlock the terminals, facilitating the removal of the terminals and convenient for connector repair.

[0010] The back of the anti-bend pin clip is provided with stepped ribs and supporting ribs. The stepped ribs correspond to the position of terminal hole I, and the supporting ribs correspond to the position of terminal hole II. After the connector is fully installed, the stepped ribs can prevent the sheath spring tongue I from deforming and enhance the primary locking strength of the terminal. At the same time, the stepped ribs and the sheath can form a complete square cavity to ensure the installation stability of the terminal in the final position. In addition, the supporting ribs can prevent the sheath spring tongue II from deforming and enhance the primary locking strength of the terminal.

[0011] The socket sleeve has socket terminal hole notches I and II, and the PLR ​​structure has PLR bosses I and II. When the PLR ​​structure is in the pre-installed position, socket terminal hole notch II mates with PLR boss II. When the PLR ​​structure is in the fully assembled position, socket terminal hole notch I mates with PLR boss I. The mate between socket terminal hole notch I and PLR boss I limits the accuracy of the PLR ​​structure in the pre-installed position, and the mate between socket terminal hole notch II and PLR boss II limits the accuracy of the PLR ​​structure in the fully assembled position.

[0012] The anti-bend pin clip is provided with a clip elastic structure, and the PLR ​​structure is provided with a PLR connection structure. The clip elastic structure and the PLR ​​connection structure are detachably connected. The inclination angle of the upper inclined surface of the anti-bend pin clip boss I is greater than the inclination angle of the lower inclined surface of the PLR ​​boss I. The length of the clip simply supported beam of the anti-bend pin clip boss I is greater than the length of the PLR ​​simply supported beam of the PLR ​​boss I. During connector separation, the anti-bend pin clip boss I first contacts the plug terminal hole notch II. Because the inclination angle of the upper slope of the anti-bend pin clip boss I is greater than the inclination angle of the lower slope of the PLR ​​boss I, the holding force of the anti-bend pin clip in the assembly position is less than the holding force of the PLR ​​structure in the assembly position. The PLR ​​structure can move the anti-bend pin clip from the fully assembled position to the pre-installed position. In addition, when the anti-bend pin clip moves to the pre-installed position, the plug terminal hole notch III and the anti-bend pin clip boss II use two straight surfaces to cooperate with each other, which makes the holding force of the anti-bend pin clip in the pre-installed position greater than the holding force of the PLR ​​structure in the pre-installed position. At this time, the anti-bend pin clip can move the PLR ​​structure to the pre-installed position, which is convenient for the next connector mating.

[0013] An assist rod is rotatably connected to the socket sleeve, and a sleeve protrusion is provided on the plug sleeve. The assist rod has an assist rod slide, and the sleeve protrusion and the assist rod slide are slidably engaged. When the assist rod rotates on the socket sleeve, the assist rod slide drives the sleeve protrusion to move, thereby causing the socket sleeve and plug sleeve to move relative to each other, realizing the assembly and unlocking of the connector; the assist rod assists in the installation and unlocking of the connector, reducing the difficulty of connector assembly.

[0014] The plug sleeve is equipped with an elastic structure. The inclined structure on the assist rod cooperates with the elastic structure of the plug sleeve. A CPA structure is inserted into the plug sleeve, and the assist rod boss on the assist rod is pressed against the CPA boss on the CPA structure. The elastic structure of the plug sleeve can lock the assist rod to prevent it from disengaging. In addition, the CPA structure can lock the elastic structure of the plug sleeve, thereby achieving a secondary locking of the assist rod.

[0015] The plug sheath is connected to a buckle, and the plug sheath is provided with a cantilever beam spring. The spring protrusion on the cantilever beam spring engages with the buckle. Both the plug sheath and the socket sheath are provided with a tail cap. The tail end of the cantilever beam spring engages with the tail cap protrusion on the tail cap. Two wedge-shaped ribs on both sides of the cantilever beam spring engage with the buckle to ensure easy buckle insertion and a tight connection with minimal wobble after insertion; to prevent the cantilever beam spring from deforming inward and to increase the buckle holding force.

[0016] The beneficial effects of this invention are as follows: the anti-bend pin clip provides position locking between the clip and the sheath by engaging with the terminal hole of the sheath, avoiding the inability to seal the plug end due to the added engagement structure; during connector mating, the anti-bend pin clip protects the plug terminals, ensuring accurate terminal positioning and preventing pin bending or dislocation during mating. Furthermore, the PLR ​​structure and the anti-bend pin clip are detachably connected and linked. When the connector is separated, the PLR ​​structure can move the anti-bend pin clip from the assembly position to the pre-installed position, ensuring accurate terminal positioning during connector mating and facilitating the reuse of the anti-bend pin clip.

[0017] After the connector is fully installed, the stepped rib can prevent the deformation of the sheath spring I and enhance the primary locking strength of the terminal. At the same time, the stepped rib and the sheath can form a complete square cavity to ensure the installation stability of the terminal in the final position. In addition, the support rib can prevent the deformation of the sheath spring II and enhance the primary locking strength of the terminal.

[0018] The engagement of the plug terminal hole notch I and the anti-bend pin clip boss I prevents the anti-bend pin clip from entering its final position during pre-installation; the engagement of the plug terminal hole notch II and the anti-bend pin clip boss II prevents the anti-bend pin clip from disengaging from its pre-installation position. The engagement of the socket terminal hole notch I and the PLR ​​boss I restricts the accuracy of the PLR ​​structure in its pre-installation position, while the engagement of the socket terminal hole notch II and the PLR ​​boss II restricts the accuracy of the PLR ​​structure in its assembly position. Through the cooperation of the PLR ​​connection structure and the clip's elastic structure, when the connector is disassembled, the anti-bend pin clip can be pulled out to its pre-installation position by the PLR ​​structure, while the PLR ​​structure can remain in its pre-installation position, facilitating connector reuse.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, such as Figure 1 , Figure 2 , Figure 4As shown, a multi-wire hybrid waterproof connector with an anti-bend pin clip includes a plug housing assembly 1 and a receptacle housing assembly 2 that are interlocked. The plug housing assembly 1 includes a plug housing 11, on which an anti-bend pin clip 12 is detachably connected. The receptacle housing assembly 2 includes a receptacle housing 21, on which a PLR structure 22 is detachably connected. The anti-bend pin clip 12 is detachably connected to the PLR ​​structure 22. During connector mating, the anti-bend pin clip 12 protects the plug terminals, ensuring accurate terminal positioning and preventing pin bending or misalignment during mating. Furthermore, the PLR ​​structure 22 is linked to the anti-bend pin clip 12. When the connector is separated, the PLR ​​structure 22 moves the anti-bend pin clip 12 from the assembly position to the pre-installed position, ensuring accurate terminal positioning during connector mating and facilitating the reuse of the anti-bend pin clip.

[0024] Furthermore, such as Figure 3 , Figure 6 , Figure 7 , Figure 8 As shown, the plug sleeve 11 is provided with plug terminal hole notches I112, II113, and III114, and the anti-bending pin clip 12 is provided with anti-bending pin clip bosses I121 and II122. When the anti-bending pin clip 12 is in the pre-installed position, the plug terminal hole notch I112 engages with the anti-bending pin clip boss I121, and the plug terminal hole notch III114 engages with the anti-bending pin clip boss II122. When the anti-bending pin clip 12 is in the fully assembled position, the plug terminal hole notch II113 engages with the anti-bending pin clip boss I121. Specifically, the plug terminal hole notch I112 is a straight notch, and the anti-bend pin clip boss I121 has beveled surfaces on both the top and bottom. The beveled surface on the bottom of the anti-bend pin clip boss I121 matches the straight surface of the plug terminal hole notch I112, which can prevent the anti-bend pin clip 12 from entering the final position during pre-installation, and can push the anti-bend pin clip boss I121 past the plug terminal hole notch I112 to reach the final position when pressure is applied; the plug terminal hole notch III114 is a straight notch, and the top of the anti-bend pin clip boss II122 is a straight surface. The straight surface matches the plug terminal hole notch III114 and the anti-bend pin clip boss II122, which prevents the anti-bend pin clip 12 from coming out of the pre-installation position.

[0025] In addition, when fully assembled, the upper inclined surface of the anti-bend pin clip boss I121 mates with the plug terminal hole notch II113.

[0026] Furthermore, such as Figure 11 , Figure 12As shown, the anti-bend pin clip 12 has terminal hole I 128 and terminal hole II 1211. Terminal I 4 and terminal II 5 are inserted into the plug sleeve 11. Terminal I 4 mates with terminal hole I 128, and terminal II 5 mates with terminal hole II 1211. When the anti-bend pin clip 12 is in the pre-installed position, the head of terminal I 4 protrudes from terminal hole I 128, and the head of terminal II 5 protrudes from terminal hole II 1211. In this embodiment, terminal I 4 and terminal II 5 are a 064 terminal and a 2.8 terminal, respectively. Terminal hole I 128 is located in the middle of the anti-bend pin clip 12, and terminal hole II 1211 is located on both sides of the anti-bend pin clip 12. The connector can simultaneously insert multiple specifications of terminals. The anti-bend pin clip 12 provides position locking between the clip and the sleeve by engaging with the terminal hole of the sleeve, avoiding the plug end from failing to seal due to the added engagement structure. Furthermore, such as Figure 12 , Figure 13 , Figure 14 As shown, the back of the anti-bend pin clip 12 has a vertical structure 125, which mates with the terminal hole of the plug sleeve 11 to form a square cavity. The square cavity limits and fixes the terminal, ensuring that the terminal is stably installed in the terminal hole and preventing the terminal from shaking. The anti-bend pin clip 12 has a repair hole I 126 and a repair hole II 1210. The repair hole I 126 corresponds to the terminal hole I 128, and the repair hole II 1210 corresponds to the terminal hole II 1211. When the anti-bend pin clip 12 is in the pre-installed position, an unlocking tool can be used to unlock the terminal through the repair hole, making it easy to remove the terminal and facilitate connector repair.

[0027] Furthermore, the back of the anti-bend pin clip 12 is provided with a stepped rib 127 and a supporting rib 129. The stepped rib 127 corresponds to the position of terminal hole I 128, and the supporting rib 129 corresponds to the position of terminal hole II 1211. Figure 15 , Figure 16 As shown, after the connector is fully installed, the stepped rib can prevent the sheath spring tongue I1111 from deforming and enhance the primary locking strength of terminal I4. At the same time, the stepped rib 127 and the sheath can form a complete square cavity to ensure the installation stability of the terminal in the final position. In addition, the support rib 129 can prevent the sheath spring tongue II from deforming and enhance the primary locking strength of terminal II5.

[0028] Furthermore, the anti-bend pin clip 12 is provided with a clip anti-misalignment structure 1212, and the plug sheath 11 is provided with a sheath anti-misalignment structure 1110. The clip anti-misalignment structure 1212 and the sheath anti-misalignment structure 1110 cooperate to prevent the anti-bend pin clip 12 from being assembled incorrectly.

[0029] Example 2, based on Example 1, provides a multi-wire hybrid waterproof connector with an anti-bend pin clip, such as... Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the socket sleeve 21 has socket terminal hole notches I 211 and II 212, and the PLR ​​structure 22 has PLR bosses I 221 and II 222. When the PLR ​​structure 22 is in the pre-assembled position, the socket terminal hole notch II 212 mates with the PLR ​​boss II 222. When the PLR ​​structure 22 is in the fully assembled position, the socket terminal hole notch I 211 mates with the PLR ​​boss I 221. The mate between the socket terminal hole notch I 211 and the PLR ​​boss I 221 limits the accuracy of the PLR ​​structure 22 in the fully assembled position, and the mate between the socket terminal hole notch II 212 and the PLR ​​boss II 222 limits the accuracy of the PLR ​​structure in the pre-assembled position. Furthermore, when the PLR ​​structure 22 is fully assembled, it presses and fixes the sealing ring 23 to ensure the sealing performance of the socket sleeve 21.

[0030] Furthermore, such as Figure 9 As shown, the anti-bend pin clip 12 is provided with a clip elastic structure 123, and the PLR ​​structure 22 is provided with a PLR connecting structure 223. The clip elastic structure 123 and the PLR ​​connecting structure 223 are detachably connected; Figure 8 As shown, the inclination angle of the upper inclined surface of the anti-bend pin clip boss I121 is greater than the inclination angle of the lower inclined surface of the PLR ​​boss I221; the length of the clip simply supported beam 1213 of the anti-bend pin clip boss I121 is greater than the length of the PLR ​​simply supported beam 224 of the PLR ​​boss I221. During connector separation, the anti-bend pin clip boss I121 first contacts the plug terminal hole notch II113. Since the inclination angle of the upper slope of the anti-bend pin clip boss I121 is greater than the inclination angle of the lower slope of the PLR ​​boss I221, and the clip elastic structure 123 is connected to the PLR ​​connection structure 223, the holding force of the anti-bend pin clip 12 in the assembly position is less than the holding force of the PLR ​​structure 22 in the assembly position. The PLR ​​structure 22 can then move the anti-bend pin clip 12 from the fully assembled position to the pre-assembled position. When the anti-bend pin clip 12 moves to the pre-assembled position, the plug terminal hole notch III114 and the anti-bend pin clip boss II122 use two straight surfaces to cooperate with each other, thus making the holding force of the anti-bend pin clip 12 in the pre-assembled position greater than the holding force of the PLR ​​structure 22 in the pre-assembled position. At this time, the anti-bend pin clip 12 can then move the PLR ​​structure 22 to the pre-assembled position.

[0031] When both the anti-bend pin clip 12 and the PLR ​​structure 22 are in the pre-installed position, the PLR ​​structure 22 is connected to the socket sleeve 21 through the engagement of the PLR ​​boss II 222 and the socket terminal hole notch II 212, and the PLR ​​boss II 222 and the socket terminal hole notch II 212 have a straight-face engagement; the anti-bend pin clip 12 is connected to the plug sleeve 11 through the engagement of the plug terminal hole notch III 114 and the anti-bend pin clip boss II 122, and the plug terminal hole notch III 114 and the anti-bend pin clip boss II 122 have a straight-face engagement. The two platforms Ⅱ122 adopt a straight-face fit; the PLR ​​structure 22 and the anti-bend pin clip 12 are connected by the fit between the clip elastic structure 123 and the PLR ​​connection structure 223. Since the holding force between the PLR ​​structure 22 and the socket sleeve 21 and the holding force between the anti-bend pin clip 12 and the plug sleeve 11 are both greater than the holding force between the PLR ​​structure 22 and the anti-bend pin clip 12, applying a pulling force in the opposite direction to the plug sleeve 11 and the socket sleeve 21 can separate the PLR ​​structure 22 and the anti-bend pin clip 12.

[0032] In addition, when the anti-bend pin clip 12 is in the pre-installed position, the unlocking tool is connected to the clip release structure 124. The pulling force applied by the clip release structure 124 can separate the plug terminal hole notch Ⅲ114 from the anti-bend pin clip boss Ⅱ122, thereby separating the anti-bend pin clip 12 from the plug sheath 11 and removing the anti-bend pin clip 12.

[0033] Furthermore, such as Figure 1 As shown, an assist rod 24 is rotatably connected to the socket sleeve 21, and a sleeve protrusion 111 is provided on the plug sleeve 11. The assist rod 24 is provided with an assist rod slide 241, and the sleeve protrusion 111 and the assist rod slide 241 are slidably engaged. When the assist rod 24 rotates on the socket sleeve 21, the assist rod slide 241 drives the sleeve protrusion 111 to move, thereby driving the socket sleeve 21 and the plug sleeve 11 to move relative to each other, realizing the assembly and unlocking of the connector; the assist rod 24 assists in the installation and unlocking of the connector, reducing the difficulty of connector assembly.

[0034] Furthermore, such as Figure 9As shown, the plug sleeve 11 is provided with a plug sleeve elastic structure 115. The inclined structure 242 on the assist rod 24 cooperates with the plug sleeve elastic structure 115. A CPA structure 13 is inserted into the plug sleeve 11. The assist rod boss 243 on the assist rod 24 is pressed and engaged with the CPA boss 131 on the CPA structure 13. The plug sleeve elastic structure 115 can cooperate with the inclined structure 242 on the assist rod 24 to lock it, preventing the assist rod 24 from disengaging from the plug sleeve elastic structure 115. In addition, the assist rod boss 243 will press down the CPA boss 131 so that the CPA boss 131 is lower than the sleeve plane 116, so that the CPA structure 13 can be inserted into the plug sleeve 11 to support the plug sleeve elastic structure 115, thereby achieving a secondary locking of the assist rod 24.

[0035] Furthermore, such as Figure 10 As shown, a buckle 14 is connected to the plug sleeve 11, and a cantilever beam spring tongue 117 is provided on the plug sleeve 11. The spring tongue protrusion 118 on the cantilever beam spring tongue 117 is hooked with the buckle 14. A tail cap 3 is provided on the plug sleeve 11. The spring tongue tail end 119 of the cantilever beam spring tongue 117 cooperates with the tail cap protrusion 31 on the tail cap 3. Two wedge-shaped ribs on both sides of the cantilever beam spring tongue 117 cooperate with the buckle 14 to ensure that the buckle 14 is easy to insert and has a tight connection with little shaking after insertion; to prevent the cantilever beam spring tongue 117 from deforming inward and to increase the buckle holding force.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
