Description

Technical Field

[0001] This utility model relates to the technical field of connector sockets, and in particular to a socket. Background Technology

[0002] Currently, high-current connectors on the market consist of a socket and a plug that interlock. The socket includes a socket housing, an inner socket sheath within the socket housing, and two pin terminals housed within the inner socket sheath. Socket end wires are connected to the pin terminals. The plug includes a plug housing, a plug core within the plug housing, and two socket terminals housed within the plug core. However, the socket of this type of high-current connector has the following drawbacks:

[0003] The connection between the terminals of the connector socket and the socket housing is fixed using a conventional structure, such as by using snap-fit ​​to fix the terminals to the socket housing. The snap-fit ​​is fixedly set on the terminals and the socket housing respectively. This method of connecting the terminals and the socket housing by snap-fit ​​reduces the difficulty of inserting the terminals into the snap-fit ​​in order to ensure that the terminals can be inserted smoothly. Consequently, the holding force of the terminals and the socket housing is also relatively small. Utility Model Content

[0004] To address the shortcomings of the aforementioned background technology, this utility model proposes a socket that solves the technical problem of insufficient holding force in the conventional structure used to fix the connection between the terminals and the socket shell of existing sockets.

[0005] The technical solution of this utility model is implemented as follows: A socket includes a socket shell, the socket shell is provided with a cavity and a tail cover, a terminal is provided in the cavity, a sealing body is provided at the end of the cavity and the sealing body is pressed against the socket shell through the tail cover, a terminal clamp is snapped onto the terminal, the terminal clamp is formed by two clamp units interlocking with each other, each clamp unit includes a body that snaps onto the terminal, the body is inserted into the cavity of the socket shell, a limiting groove is provided on the inner wall of the cavity of the socket shell, and a cantilever is provided on the body that can stop and cooperate with the limiting groove. Two clamping units are interlocked to achieve the structural connection between the terminal and the terminal clamp. The terminal is locked to the socket housing by the stop action of the cantilever on the terminal clamp and the limiting groove. The cantilever design provides greater elasticity while locking the terminal to the socket housing. The insertion force is small when the terminal is inserted into the socket housing. The cantilever design increases the holding force of the terminal in the socket housing while reducing the force of the terminal being inserted into the socket housing. This solves the technical problem of low holding force when the connection between the terminal and the socket housing of the existing socket uses a conventional structure.

[0006] Preferably, the two clamping units have identical structures, the terminals are circular pin terminals, and both clamping units are arc-shaped. When the two clamping units are snapped together, they form a terminal clamp that fits against the circular pin terminal. This application uses two identical clamping units that snap together to achieve structural connection between the terminal and the terminal clamp, saving space, simplifying operation, enabling batch wire harness crimping, and improving efficiency.

[0007] Preferably, a baffle is integrally connected to the end of the main body, the baffle is perpendicular to the main body, and the terminal has a slot. The baffle is inserted into the slot and is perpendicular to the insertion direction of the terminal. When the baffle integrally connected to the main body is inserted into the slot, and two identical clamping units are fastened together, the two baffles form a structure that limits the engagement with the slot, and the direction of the engagement between the two baffles and the slot is perpendicular to the insertion direction of the terminal. This ensures that the two baffles are always engaged with the slot during terminal insertion, guaranteeing the baffle's limiting effect on the terminal.

[0008] Preferably, the baffle is semi-circular. When the baffle is semi-circular, when two identical clamping units are fastened together, the two baffles form a circular baffle structure that cooperates with the slot for limiting, which helps to improve the limiting effect of the baffle on the terminal.

[0009] Preferably, a stop block is provided on the inner wall of the cavity of the socket housing, and the stop block cooperates with the baffle. The stop block is provided to prevent the terminal from being excessively inserted into the socket housing, and the stop block plays a role in limiting the depth of the terminal inserted into the socket housing.

[0010] Preferably, the main body is provided with an anti-misalignment groove, and the inner wall of the socket housing is provided with an anti-misalignment rib, which is adapted to the anti-misalignment groove. The assembled terminal clamp is guided into the socket housing through the anti-misalignment groove, and the anti-misalignment rib positions the insertion position of the terminal clamp.

[0011] Preferably, at least two anti-misalignment ribs are provided on the inner wall of the cavity of the socket housing. The socket housing has at least two anti-misalignment ribs on its inner wall and corresponding anti-misalignment grooves on its body. The provision of at least two anti-misalignment ribs further enhances the limiting effect during the insertion process of two identical clamping units interlocking to form a terminal clamp, effectively preventing the two interlocking clamping units from loosening during insertion.

[0012] Preferably, the anti-misalignment groove is funnel-shaped. The funnel-shaped anti-misalignment groove facilitates the quick insertion of the assembled terminal clamp into the anti-misalignment rib, which helps to improve assembly efficiency.

[0013] Preferably, the socket housing has a plug inside, and the front end of the terminal has a connection hole, with the end of the plug engaging with the connection hole. The plug serves to prevent finger contact, ensuring safety during socket use.

[0014] Preferably, the socket housing is provided with a snap-fit ​​structure for connection with the user's bracket, and the snap-fit ​​structure engages with the socket housing. This snap-fit ​​structure ensures reliable connection and simple operation, meeting the wiring requirements of confined spaces.

[0015] The beneficial effects of this utility model are:

[0016] 1. Two clamping units are interlocked to achieve the structural connection between the terminal and the terminal clamp. The terminal is clamped and fixed to the socket housing by the stop cooperation between the cantilever on the terminal clamp and the limiting groove. The cantilever design provides greater elasticity while achieving the clamping and fixing of the terminal to the socket housing. The insertion force is small when the terminal is inserted into the socket housing. The cantilever design increases the holding force of the terminal in the socket housing while reducing the force of the terminal being inserted into the socket housing.

[0017] 2. The terminal clamp and the terminal are fixed by two identical clamp units interlocking with each other. The connection between the terminal and the socket housing is achieved by using two identical clamp units interlocking with each other, which saves a lot of space and cost.

[0018] 3. The assembled terminal clamp is guided into the socket housing through the anti-misalignment groove, and the anti-misalignment rib positions the terminal clamp in the insertion position.

[0019] 4. It connects to the user's bracket via a snap-fit ​​structure, ensuring a reliable connection and simple operation, thus meeting the wiring requirements in confined spaces. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, a socket, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the socket includes a socket housing 1, which has a cavity and a tail cap 11. A terminal 2 is provided in the cavity, and a sealing body 10 is provided at the end of the cavity. The sealing body 10 is pressed against the socket housing 1 through the tail cap 11. A terminal clamp 3 is snapped onto the terminal 2. The terminal clamp 3 is formed by two clamp units that are interlocked with each other. Each clamp unit includes a body 4 that snaps onto the terminal 2. The body 4 is inserted into the cavity of the socket housing 1. A cantilever 5 is provided on the body 4. A limiting groove 16 is provided on the inner wall of the cavity of the socket housing 1. When the terminal clamp 3 snaps onto the terminal 2 and is fully inserted into the cavity of the socket housing 1, the cantilever 5 and the limiting groove 16 are engaged to stop it. Two clamping units are interlocked to achieve the structural connection between the terminal and the terminal clamp. The terminal 2 is clamped and fixed to the socket housing 1 by the stop cooperation between the cantilever 5 on the terminal clamp and the limiting groove 16. The cantilever 5 provides greater elasticity while achieving the clamping and fixing of the terminal 2 to the socket housing 1. The insertion force of the terminal 2 into the socket housing 1 is small. The cantilever 5 increases the holding force of the terminal 2 in the socket housing 1 while reducing the force of the terminal 2 inserting into the socket housing 1. This solves the technical problem of low holding force when the connection between the terminal and the socket housing of the existing socket uses a conventional structure.

[0032] The sealing body 10 on the socket serves a sealing function. The longitudinal section of the sealing body 10 is L-shaped. One end of the L-shaped sealing body extends into the cavity of the socket housing 1, and the other end is pressed against the end face of the cavity of the socket housing 1 by the tail cover 11. The tail cover 11 and the socket housing 1 are engaged by the existing convex-concave fit.

[0033] Example 2, based on Example 1, a socket, such as Figure 5 , Figure 6 and Figure 7 As shown, the two clamping units have identical structures. Terminal 2 is a circular pin terminal, and both clamping units are arc-shaped. When the two clamping units are snapped together, they form a terminal clamp that fits against the circular pin terminal. This application uses two identical clamping units to snap together to achieve structural connection between terminal 2 and terminal clamp 3, saving space, simplifying operation, enabling batch wire harness crimping, and improving efficiency.

[0034] Example 3, based on Example 2, a socket, such as Figure 5 , Figure 6 and Figure 7As shown, a baffle 8 is integrally connected to the end of the main body 4. The baffle 8 is perpendicular to the main body 4. The terminal 2 is provided with a slot 9. The baffle 8 is inserted into the slot 9 and is perpendicular to the insertion direction of the terminal 2. By inserting the baffle 8, which is integrally connected to the main body 4, into the slot 9, when two identical clamping units are fastened together, the two baffles 8 form a structure that limits the engagement with the slot 9. The direction of the limiting engagement between the two baffles 8 and the slot 9 is perpendicular to the insertion direction of the terminal 2, so that the two baffles 8 are always limited to the slot 9 during the insertion of the terminal 2, ensuring the limiting effect of the baffle 8 on the terminal 2.

[0035] Example 4, based on Example 3, a socket, such as Figure 5 , Figure 6 and Figure 7 As shown, the baffle 8 is semi-circular. When the baffle 8 is semi-circular, when two identical clamping units are fastened together, the two baffles 8 form a circular baffle structure that cooperates with the slot 9 for limiting, which helps to improve the limiting effect of the baffle 8 on the terminal 2.

[0036] Example 5, based on Example 4, a socket, such as Figure 3 and Figure 4 As shown, a stop block 15 is provided on the inner wall of the cavity of the socket housing 1, and the stop block 15 is in a stop-locking engagement with the baffle 8. The stop block 15 is provided to prevent the terminal 2 from being excessively inserted into the socket housing 1, and the stop block 15 plays a role in limiting the depth of the terminal 2 inserted into the socket housing 1. Preferably, the stop block 15 is located at the beginning of the socket housing 1, and the limiting groove 16 is located at the end of the socket housing 1. This arrangement allows the cantilever 5 on the end of the terminal clamp 3 to be in a stop-locking engagement with the socket housing 1, and the baffle 8 at the beginning of the terminal clamp 3 to be in a stop-locking engagement with the stop block 15 on the socket housing 1. The terminal clamp 3 achieves a stop-locking engagement at both ends of the terminal 2, further ensuring the stability of the position of the terminal 2.

[0037] Example 6: Based on any one of Examples 1 to 5, a socket, such as... Figure 6 , Figure 7 and Figure 8 As shown, the main body 4 is provided with an anti-misalignment groove 6, and the inner wall of the socket housing 1 is provided with an anti-misalignment rib 7, which is adapted to the anti-misalignment groove 6. The assembled terminal clamp 3 is guided into the socket housing 1 through the anti-misalignment groove 6, and the anti-misalignment rib 7 positions the insertion position of the terminal clamp 3.

[0038] Example 7, based on Example 6, a socket, such as Figure 6 , Figure 7 and Figure 8As shown, at least two anti-misalignment ribs 7 are provided on the inner wall of the cavity of the socket housing 1. The socket housing 1 has at least two anti-misalignment ribs 7, and the main body 4 has corresponding anti-misalignment grooves 6. The provision of at least two anti-misalignment ribs 7 further improves the limiting effect on the insertion process of two identical clamping units interlocking to form a terminal clamp 3, effectively preventing the two interlocking clamping units from loosening during insertion.

[0039] Example 8, based on Example 7, a socket, such as Figure 7 As shown, the anti-misalignment groove 6 is trumpet-shaped. The trumpet-shaped anti-misalignment groove 6 facilitates the quick insertion of the assembled terminal clamp 3 into the anti-misalignment rib 7, which helps to improve assembly efficiency.

[0040] Example 9, based on Example 5 or 7, a socket, such as Figure 3 As shown, the socket housing 1 has a plug 13 inside, and the front end of the terminal 2 has a connection hole 14. The end of the plug 13 is inserted into the connection hole 14. The plug 13 is designed to prevent finger contact, ensuring safety during socket use.

[0041] Example 10, based on Example 9, a socket, such as Figure 3 and Figure 8 As shown, the socket housing 1 is provided with a snap-fit ​​structure 12 for connection with the user's bracket. The snap-fit ​​structure 12 engages with the socket housing 1. The connection via the snap-fit ​​structure 12 is reliable, simple to operate, and can meet the wiring requirements in confined spaces. Preferably, the snap-fit ​​structure 12 engages with the socket housing 1 by fixing a groove 17 to the socket housing 1. A protrusion 18 is connected to the groove wall of the groove 17. The bottom of the snap-fit ​​structure 12 has a protrusion that engages with the protrusion 18. When the snap-fit ​​structure 12 is inserted into the groove 17, the bottom protrusion of the snap-fit ​​structure 12 elastically deforms and passes over the protrusion 18. After passing over the protrusion 18, the bottom protrusion of the snap-fit ​​structure 12 engages with the protrusion 18 to complete the snap-fit ​​between the snap-fit ​​structure 12 and the socket housing 1.

[0042] In Example 10, each component is processed and then assembled. During assembly, two identical clamping units are fastened to the outside of terminal 2, forming terminal clamp 3. At this time, the body 4 is in contact with the circumferential surface of terminal 2, and the baffle 8 is inserted into the slot 9. Then, this whole assembly is guided into the socket housing 1 through the anti-misalignment rib 7. When terminal 2 is fully inserted, the cantilever 5 on the tail of terminal clamp 3 is engaged with the socket housing 1, and the baffle 8 at the head of terminal clamp 3 is engaged with the stop block 15 on the socket housing 1. Then, the plug 13 is inserted from the head of the socket housing 1, so that the plug 13 is inserted into the connection hole 14 at the front end of terminal 2. Then, the snap-fit ​​structure 12 is snapped onto the socket housing 1 to form the socket of this application.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
