Description

Electrical connector

This creation relates to an electrical connector, in particular to an electrical connector with a contact spring.

Chinese invention patent CN106340743B discloses a cylindrical crown spring, which includes an upper end belt and a lower end belt arranged at both ends of the cylindrical crown spring, and a plurality of reeds arranged between the upper end belt and the lower end belt. Each reed has a contact portion extending axially to the cylindrical crown spring; the reed includes a reed I and a reed II, and the reed I and the reed II are alternately distributed in the circumferential direction; the contact includes The reed I contact portion arranged in the middle of the reed I and the reed II contact portion arranged in the middle of the reed II; the reed I contact portion and the reed II contact portion are layered in the axial direction of the cylindrical crown spring Distribution; the reed II is a cantilever beam structure connected with the upper end band or the lower end band, the reed II is symmetrically distributed toward the center plane of the cylindrical crown spring; the end of the reed II of the cantilever beam structure has a cylindrical The sliding surface extending from the central surface of the cylindrical crown spring; during the insertion of the pin, the sliding surface contacts the inner wall of the crown spring installation groove of the socket and slides toward the central surface of the cylindrical crown spring. The crown spring has many contact points but a complicated structure.

Therefore, it is necessary to provide an improved electrical connector to solve the above problems.

The purpose of this creation is to provide an electrical connector with more contact points.

In order to achieve the above-mentioned purpose, this creation can adopt the following technical solutions:

An electrical connector, which includes: a contact spring, which includes a first ring and a second ring arranged adjacent to each other, a connecting bridge that integrally connects the first ring and the second ring to each other, and a plurality of first rings. Elastic pieces and a plurality of second elastic pieces; and a sleeve for accommodating the contact spring; wherein, the first and second circular rings respectively have first round edges on the same side, and the plurality of first elastic pieces starts from the first The first round side of a ring extends obliquely inward, a plurality of the second elastic pieces extend obliquely inward from the first round side of the second ring, and the first and second elastic pieces extend in the same direction and are both provided with Contact point.

Compared with the conventional technology, this creation has the following effects: the contact spring of this creation has more contact points to transmit large currents.

In order to facilitate a better understanding of the purpose, structure, features, and effects of the creation, the creation is further explained in conjunction with the drawings and specific implementations.

Please refer to the first to second figures, an electrical connector 100 for transmitting large current is disclosed, which includes a sleeve 10 and a contact spring 2 housed in the sleeve 10. The sleeve 10 is made of insulating plastic material, and the contact spring 20 is made of metal material.

The contact spring 2 includes a first circular ring 21 and a second circular ring 22 arranged adjacent to each other, a connecting bridge 26 integrally connecting the first circular ring 21 and the second circular ring 22 to each other, and a plurality of first elastic pieces 24 and a plurality of Two shrapnel 25. The first and second rings 21 and 22 respectively have a first round edge 210 on the same side. A plurality of first elastic pieces 24 extend obliquely inward from the first round edge 210 of the first ring 21, and the end of the first elastic piece 24 is not Extend to the second ring 22. The plurality of second elastic pieces 25 extend obliquely inward from the first circular edge 210 of the second ring 22, and the first and second elastic pieces 24 and 25 extend in the same direction and are both provided with contact points 20. The first and second elastic pieces 24, 25 are arranged in two-by-two alignment in the extending direction. In this way, the contact points are arranged regularly and in large numbers, which is beneficial to the stable transmission of large currents.

The contact spring 20 includes two connecting bridges 26 corresponding to each other. The plurality of first elastic pieces 24 are divided into two groups by the connecting bridges 26, and the first elastic pieces 24 in each group are arranged adjacent to each other. The contact spring 2 also includes a third ring 23. The first, second and third rings 21, 22, 23 are arranged in sequence, and the second and third rings 22, 23 are integrated with each other by two connecting bridges 27. Connected, the plurality of second elastic pieces 25 are divided into two groups by the connecting bridge 27, and the second elastic pieces 25 in each group are arranged adjacent to each other. The connecting bridges 26 and 27 are aligned with each other along the arrangement direction of the three rings, and the three rings are connected as a whole by the connecting bridges 26 and 27.

The first and second elastic pieces 24, 25 are provided with convex hulls protruding inward, and the convex hulls form the above-mentioned contact point 20. In other embodiments, the contact point 20 is not limited to a convex hull, and can be set as a simple fulcrum by itself. Bending part, etc. The free ends of the first and second elastic pieces 24 and 25 are suspended, and the convex hull is close to the free end. The inner side of the convex hull protrudes inward for a certain distance from the end of the elastic piece. The convex hull has a smooth contact arc surface. The mating pin 900 frictionally contacts the arc surface to insert the contact spring 2, and finally the mating pin 900 electrically abuts the contact arc surface.

The sleeve 10 includes a receiving cavity 101 penetrating forwardly for installing and receiving the contact spring 2. The first, second, and third rings 21, 22, and 23 are attached to the inner wall 102 of the receiving cavity, and the connecting bridges 26, 27 connect and fix the three rings and simultaneously attach to the inner wall 102 of the receiving cavity. The first and second elastic pieces 24 and 25 do not stick to the inner wall surface 102 due to obliquely extending inwardly, so there is an elastically rotatable space between the first and second elastic pieces 24 and 25. The first and third rings 21 and 23 are confined in the containing cavity, and the constraining method can be achieved by setting a step on the inner wall surface.

In summary, this creation meets the requirements for a new patent, and Yan filed a patent application in accordance with the law. However, the above are only the preferred embodiments of this creation, and the scope of this creation is not limited to the foregoing embodiments. For those who are familiar with the techniques of this case and make equivalent modifications or changes based on the spirit of this creation, they are all Should be covered in the scope of the following patent applications.
