Description

Technical Field

[0001] This utility model relates to the field of connectors, and more particularly to a spring-loaded locking socket connector. Background Technology

[0002] In the field of electronic assembly, pin-type components typically need to be electrically connected to mounting holes on circuit boards. Current technology generally uses soldering to fix the pins in the mounting holes to achieve conductivity. However, soldering operations usually require soldering equipment, are cumbersome, have low processing efficiency, and are not conducive to automated production. Furthermore, once the soldered connection is formed, it is difficult to disassemble, hindering subsequent maintenance and replacement. To improve the installation efficiency and ease of maintenance of pins, socket connectors can be installed on the mounting holes of the circuit board to achieve quick connection of pins through plugging and unplugging. However, traditional socket connectors are difficult to reliably lock the pins in use, exhibiting insufficient clamping force and unstable positioning. In environments with high vibration, the pins are prone to loosening or detachment, affecting the stability of the electrical connection and failing to meet the conductivity requirements under high current conditions.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a spring-loaded locking socket connector that is easy to assemble and securely locked.

[0005] To achieve this objective, the present invention adopts the following technical solution: a spring-loaded locking type socket connector, comprising a housing sleeve and an elastic snap fastener;

[0006] The outer sleeve has a receiving through hole inside, and the elastic fastener is fastened in the receiving through hole. The elastic fastener has a socket for inserting a pin.

[0007] The top of the receiving through hole is provided with a transition arc surface, and the top of the elastic buckle is provided with several limiting ears along the circumference. The limiting ears are used to engage with the transition arc surface when the elastic buckle is inserted into the receiving through hole.

[0008] The bottom of the elastic buckle is provided with several elastic claws along the circumferential direction. The elastic claws are used to apply an elastic clamping force to the pin in the socket to lock and fix the pin in the elastic buckle.

[0009] In the above technical solution, the spring-loaded locking socket connector has an opening gap along the axial direction for the elastic snap fastener to provide elastic deformation clearance space when the elastic snap fastener is inserted into the receiving through hole.

[0010] The spring-loaded locking socket connector described above also includes a rubber plug, which is located at the bottom of the outer casing sleeve to seal the receiving through hole.

[0011] In the above technical solution, the spring-loaded locking socket connector has an annular flange at the top of the outer sleeve, which is used to engage with the edge of the socket on the mounting surface.

[0012] Using the above technical solution, in the spring-loaded locking socket connector, the cross-sectional width of the elastic claw gradually increases in the direction away from the center of the socket.

[0013] In the above technical solution, the bottom of the outer sleeve of the spring-loaded locking socket connector is provided with a guide slope, which is used to guide the outer sleeve to be inserted into the edge of the socket on the mounting surface.

[0014] In the above technical solution, the outer sleeve of the spring-loaded locking socket connector is made of brass, and the elastic buckle is made of beryllium copper.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The outer sleeve of this utility model can be inserted into the insertion hole on the mounting surface. The inner part of the outer sleeve is provided with a receiving through hole. The elastic buckle can be engaged with the transition arc surface at the top of the receiving through hole through the limiting folding lug, thereby realizing the stable positioning of the elastic buckle and preventing it from loosening during use. The elastic claws provided at the bottom of the elastic buckle can automatically open and spring back to clamp when the pin is inserted. This not only reduces the insertion resistance and improves the assembly efficiency, but also forms a reliable clamping force after the pin is in place, preventing the pin from loosening and falling out due to vibration or external force. In addition, the elastic claws can form a multi-point contact structure with the pin, effectively improving the electrical connection stability and conductivity of the pin, and meeting the connection requirements under high current conditions.

[0024] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 5As shown, this utility model embodiment provides a spring-loaded locking type connector with a socket 20, including a sleeve housing 1 and an elastic fastener 2. The sleeve housing 1 has a receiving through hole 10 inside, and the elastic fastener 2 is engaged in the receiving through hole 10. The elastic fastener 2 has a socket 20 for inserting a pin. The receiving through hole 10 has a transition arc surface 101 at its top. The top of the elastic fastener 2 has several limiting ears 21 along its circumference. The limiting ears 21 are used to engage with the transition arc surface 101 when the elastic fastener 2 is inserted into the receiving through hole 10. During the process of inserting the elastic fastener 2 into the sleeve housing 1, the limiting ears 21 can engage with the transition arc surface 101, thereby achieving axial positioning and fixing of the elastic fastener 2, preventing the elastic fastener 2 from loosening or falling off in the receiving through hole 10, and effectively improving the assembly structure stability between the elastic fastener 2 and the sleeve housing 1.

[0028] The bottom of the elastic locking member 2 is provided with several elastic claws 22 along the circumferential direction. The elastic claws 22 are used to apply an elastic clamping force to the pin in the socket 20 to lock and fix the pin in the elastic locking member 2. When the pin is inserted into the socket 20 inside the elastic locking member 2 from the outside, the elastic claws 22 expand radially under the pushing action of the outer wall of the pin, thereby providing clearance space for the insertion of the pin and effectively reducing the insertion resistance. When the pin is inserted into place, the elastic claws 22 can stick tightly to the surface of the pin, thereby applying a continuous clamping force to the pin and preventing the pin from loosening or falling off under vibration or external force. At the same time, through multi-point contact, the reliability of the electrical connection of the pin is effectively improved, avoiding the problem of poor contact and meeting the contact conduction requirements of the pin under high current conditions.

[0029] like Figure 1 and Figure 4 As shown, the elastic buckle 2 is further provided with an opening slit 23 along the axial direction. The opening slit 23 is used to provide elastic deformation avoidance space for the elastic buckle 2 when it is inserted into the receiving through hole 10. The setting of the opening slit 23 allows the elastic buckle 2 to shrink and deform appropriately in the radial direction when it is squeezed, and to achieve radial tightening through elastic recovery after being inserted into place, thereby enhancing its positioning stability in the receiving through hole 10.

[0030] like Figure 1 As shown, the connector further includes a rubber plug 3, which is located at the bottom of the sleeve housing 1 to seal the receiving through hole 10 and prevent foreign objects or dust from entering the connector from below. It should be noted that when the connector is in use, the rubber plug 3 needs to be removed from the receiving through hole 10.

[0031] like Figure 2 and Figure 5As shown, furthermore, the top of the sleeve housing 1 is provided with an annular flange 11. The annular flange 11 is used to engage with the edge of the insertion hole 20 on the mounting surface, thereby forming a limiting fit with the mounting hole, playing a positioning and stopping role, so that the sleeve housing 1 will not slip axially or loosen after being inserted into the mounting hole, effectively improving the assembly efficiency of the connector. It should be noted that this utility model is usually inserted into the electrical insertion hole 20 on the circuit board.

[0032] like Figure 4 As shown, further, the cross-sectional width of the elastic claw 22 gradually increases in the direction away from the center of the insertion hole 20. During the process of inserting the pin into the elastic buckle 2, the first contact is made with the inner side of the elastic claw 22 near the center of the insertion hole 20. The cross-section here is narrower and the stiffness is smaller, which can generate elastic opening first when the pin is pushed in, reducing the initial insertion force and improving the assembly smoothness. As the pin is gradually inserted, the stiffness of the elastic claw 22 increases and the rebound force is stronger. It can apply a greater clamping force to the pin after it is in place, forming a stable lock and effectively improving the connection stability between the elastic buckle 2 and the pin.

[0033] like Figure 1 and Figure 2 As shown, furthermore, the bottom of the sleeve housing 1 is provided with a guide slope 12, which is used to guide the sleeve housing 1 to be inserted into the edge of the insertion hole 20 on the mounting surface. When the connector is assembled into the mounting hole of the circuit board or device housing, the guide slope 12 can automatically center and align with the mounting hole when the sleeve housing 1 contacts the edge of the mounting hole, avoiding problems such as jamming or misalignment caused by edge interference.

[0034] Furthermore, the sleeve housing 1 is made of brass, and the elastic snap fastener 2 is made of beryllium copper. Brass has good mechanical strength, corrosion resistance, and electrical conductivity. The sleeve housing 1 is made of brass, which can improve the structural stability and electrical connection reliability of the connector. Beryllium copper has excellent elastic recovery ability and fatigue resistance, which can maintain reliable clamping force during multiple insertion and removal operations of the elastic snap fastener 2, and is not prone to permanent deformation, thus effectively improving the service life of the connector.

[0035] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
