Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a crown spring connector. Background Technology
[0002] The crown spring connector that provides current input to medical devices has a problem with spring contacts falling off. A typical crown spring connector consists of a spring contact 01 and a socket terminal 02. Figure 1 As shown, the socket terminal 02 adopts an integrated design. When assembling the crown spring connector, the spring is first inserted into the socket terminal, and then the outer end of the socket terminal is closed. Currently produced products have different sizes and shapes of closed circles, and the shape of the closed circle cannot be controlled. The spring is easy to fall off from the closed circle.
[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a crown spring connector. Utility Model Content
[0004] The main technical problem solved by this utility model is to provide a crown spring connector. The split design effectively solves the problem of crown spring falling off, increases the contact area between the body and the copper sleeve, and increases the holding force between the body and the copper sleeve, thus solving the problem of crown spring falling off due to large insertion and extraction forces and the requirement for insertion and extraction life.
[0005] To solve the above-mentioned technical problems, the present invention provides a crown spring connector, which includes a crown spring and a crown spring terminal. The crown spring terminal adopts a split structure and includes a sleeve and a socket body. The sleeve is provided with a stepped hole in the axial direction. The stepped hole includes a mounting hole for placing the crown spring and a retaining hole to prevent the crown spring from falling off. The socket body is inserted into one end of the sleeve near the mounting hole. The socket body and the sleeve are fixed together by riveting.
[0006] Preferably, one end of the socket body is provided with a insertion part that can be inserted into the mounting hole, and the outer diameter of the insertion part is not greater than the diameter of the mounting hole.
[0007] Preferably, the insertion part is designed to be elongated.
[0008] Preferably, the diameter of the retaining hole is smaller than the maximum outer diameter of the crown spring.
[0009] Preferably, the sleeve and socket body are made of copper.
[0010] Preferably, the crown spring terminal includes two annular portions that contact the inner wall of the mounting hole and a spring portion located between the two annular portions, wherein the spring portion includes a plurality of springs arranged in a ring and protruding toward the center of the inner ring.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The crown spring terminal is designed as a split type. The crown spring is first inserted into the copper sleeve, then the socket body is inserted, and then the copper sleeve and the body are riveted together. The copper sleeve and the body are firmly fixed together by riveting, which can effectively solve the problem of crown spring falling off.
[0013] The increased contact area between the body and the copper sleeve enhances the holding force between them, thus meeting the different customer requirements for insertion and extraction life. This structure, with its increased contact area, can also more effectively solve the problems of crown spring detachment due to high insertion and extraction force and the need for improved insertion and extraction life.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0021] Please see Figures 3 to 4 The embodiments of this utility model include:
[0022] A crown spring connector includes a crown spring 1 and a crown spring terminal 2. The crown spring terminal 2 adopts a split structure and includes a sleeve 21 and a socket body 22. The sleeve 21 is axially provided with a stepped hole 20. The stepped hole 20 includes a mounting hole 201 for placing the crown spring 1 and a retaining hole 202 to prevent the crown spring 1 from falling off. The diameter of the retaining hole 202 is smaller than the maximum outer diameter of the crown spring 1. The socket body 22 is inserted into one end of the sleeve 21 near the mounting hole 201. The socket body 22 and the sleeve 21 are fixed together by riveting, which can effectively solve the problem of the spring falling off.
[0023] One end of the socket body 22 is provided with an insertion part 220 that can be inserted into the mounting hole 201. The outer diameter of the insertion part 220 is not greater than the diameter of the mounting hole 201. The insertion part 220 is designed to increase the contact area between the socket body 22 and the sleeve 21, thereby increasing the holding force between the socket body 22 and the sleeve 21 to meet the needs of different customers for insertion and removal life. Due to the increased contact area, this structure can also more effectively solve the problems of spring detachment caused by large insertion and removal forces and the need for insertion and removal life.
[0024] The sleeve 21 and the socket body 22 are made of copper.
[0025] The crown spring 1 includes two annular portions 10 that contact the inner wall of the mounting hole 201 and a spring portion 11 located between the two annular portions 10. The spring portion 11 includes a plurality of spring pieces 12 arranged in a ring and protruding toward the center of the inner ring. The arrangement of the spring pieces 12 ensures that they will make close contact with the mating plug in the future.
[0026] This utility model discloses a crown spring connector with a split design that effectively solves the problem of crown spring detachment. It increases the contact area between the body and the copper sleeve, and increases the holding force between the body and the copper sleeve, thus solving the problems of crown spring detachment caused by large insertion and extraction forces and the need for insertion and extraction life.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
