Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more particularly to a connecting contact finger for an electrical connector. Background Technology

[0002] With the rapid growth of the consumer electronics, automotive electronics, and communication terminal markets, and the continuous shift of global connector production capacity to Asia and China, Asia has become the region with the greatest development potential for the connector market, while China will become the world's fastest-growing and largest connector market.

[0003] For example, patent application CN 212626181 U discloses a conductive connector with a spring-finger structure, including a conductive sleeve, a connecting seat, and a conductive core. One end of the conductive sleeve has a socket along its axial direction. The inner wall of the socket has a first annular groove and a second annular groove formed sequentially from the inside to the outside. A first spring-finger is installed in the first annular groove, and a second spring-finger is installed in the second annular groove. The first spring-finger is inclined radially, while the second spring-finger is inclined axially. The connecting seat is fixedly connected to the conductive core near the conductive sleeve. The conductive core corresponds to and fits the socket. A first slot and a second slot are formed sequentially on the outer circumference of the conductive core. The depth of the first slot is less than the depth of the second slot. However, in the above method, the inner ring of the spring-finger abuts against the outer wall of the conductive core, using the spring force for positioning. This positioning method cannot ensure positioning accuracy and poses a safety hazard. In addition, the structure of the first and second spring contacts assembled on the conductive sleeve is also relatively complex, which is not conducive to mass production and maintenance, and is time-consuming and labor-intensive, thus having significant limitations. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a connecting contact finger for an electrical connector.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A connecting contact finger for an electrical connector includes a tubular body. One side of the body has a connecting portion, and the other side has a locking portion for quick connection with a conductive core. The locking portion includes at least a fixed end fixed to the body. A set of spring pieces integrally formed therewith are evenly distributed on the outer circumferential surface of the fixed end. There is a gap between adjacent spring pieces. Each spring piece includes an integrally formed horizontal portion and an inclined portion. The maximum diameter of the inclined portion is larger than the maximum diameter of the horizontal portion. An elastic retaining spring is sleeved on the horizontal portion. The elastic retaining spring can apply a force to the end side of the horizontal portion close to the inclined portion, causing it to deform.

[0007] Preferably, the spring is spoon-shaped, and the horizontal part and the inclined part are transitioned by a chamfer.

[0008] Preferably, the connecting part is fixed to the main body by welding, riveting or screwing.

[0009] Preferably, the connecting part is rectangular or cylindrical.

[0010] Preferably, a locking groove is formed on the outer circumferential surface of the main body.

[0011] Preferably, twelve of the spring pieces are evenly distributed on the outer circumferential surface of the fixed end.

[0012] The beneficial effects of this utility model are mainly reflected in:

[0013] 1. The design is ingenious. After the conductive core is pushed to the horizontal part, the elastic spring is pushed to the connection position between the horizontal part and the inclined part, so that the horizontal part is tightened by force, thereby clamping the conductive core tightly. This operation is simple and convenient, easy to install and disassemble, and greatly improves work efficiency. At the same time, it can be observed in real time to ensure the accuracy of positioning and has a wide range of applications.

[0014] 2. The use of chamfered transition is to avoid hard interference between the conductive core and the spring, which could lead to damage to the conductor core or spring, thus extending the service life and maximizing safety. Attached Figure Description

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings:

[0016] Figure 1: Perspective view of a preferred embodiment of the present invention. Detailed Implementation

[0017] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] As shown in Figure 1, this utility model discloses a connecting contact finger for an electrical connector, including a tubular body 1. One side of the body 1 is provided with a connecting part 2, and the other side is provided with a locking part 3 for quick connection with a conductive core rod. The locking part 3 locks the conductive core rod to complete the insertion between terminals. This operation is simple, convenient and stable and reliable.

[0021] The locking part 3 includes at least a fixed end 31 fixed to the main body 1. A set of spring pieces 32 integrally formed therewith are evenly distributed on the outer circumferential surface of the fixed end 31. In this preferred embodiment, twelve spring pieces 32 are evenly distributed on the outer circumferential surface of the fixed end 31. Of course, the number of spring pieces 32 can also be other and can be adjusted according to actual needs. There is a gap between adjacent spring pieces 32. Each spring piece 32 includes an integrally formed horizontal part 33 and an inclined part 34. The maximum diameter of the inclined part 34 is larger than the maximum diameter of the horizontal part 33.

[0022] In this preferred embodiment, the spring piece 32 is spoon-shaped, and the horizontal portion 33 and the inclined portion 34 are transitioned by a chamfer. The chamfer transition avoids hard interference between the conductive core rod and the spring piece, preventing damage to the core rod or spring piece, thus extending service life and maximizing safety. Of course, the spring piece 32 can also be of other shapes, and adjustments can be made according to actual needs; all of these fall within the protection scope of this utility model and will not be elaborated upon here.

[0023] An elastic retaining spring 35 is fitted onto the horizontal portion 33. The elastic retaining spring 35 can apply a force to the end side of the horizontal portion 33 that is close to the inclined portion 34, causing it to deform. This ingenious design allows the conductive core rod to be pushed to the horizontal portion, and then pushed until the elastic retaining spring moves to the connection position between the horizontal and inclined portions. This causes the horizontal portion to tighten under force, thus firmly clamping the conductive core rod. This operation is simple and convenient, facilitating installation and disassembly, greatly improving work efficiency. Simultaneously, real-time observation is possible to ensure positioning accuracy, making it widely applicable.

[0024] The connecting part 2 is fixed to the main body 1 by welding, riveting, or screwing. Of course, other connection methods, such as snap-fit, can also be used, all of which fall within the protection scope of this utility model and will not be elaborated on here. The connecting part 2 is rectangular or cylindrical to improve the convenience of subsequent connection steps and greatly improve work efficiency.

[0025] In this preferred embodiment, a locking groove 11 is provided on the outer circumferential surface of the main body 1. The locking groove 11 can be used for positioning or connection, thereby improving the convenience of operation.

[0026] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0027] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
