Electrical connector

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

Chinese Invention Patent No. CN102005663A discloses a crown spring cage pin socket element and its socket. The crown spring cage socket includes an inner sleeve. The outer circumference of the inner sleeve is provided with an outer sleeve, and the inner hole of the inner sleeve penetrates A crown spring is provided, and the port portion of the inner hole of the outer sleeve is symmetrically provided with two mutually parallel elastic clamping strips, and the distance between the two elastic clamping strips is smaller than the minimum inner diameter of the crown spring.

The crown spring cage type pin jack assembly includes a pin and a jack, the jack includes an inner sleeve, the outer circumference of the inner sleeve is provided with an outer sleeve, and the inner hole of the inner sleeve is penetrated with a crown spring. The port portion of the inner hole of the outer jacket is symmetrically provided with two parallel elastic clamping strips, and the distance between the two elastic clamping strips is smaller than the inner diameter of the crown spring. The pin includes a pin-shaped plug connector, and the peripheral surface of the pin-shaped plug connector is provided with a clamping structure that is tightly fitted with two elastic clamping strips. An elastic clip strip is set at the port of the jack. The snap-fit structure on the pin is matched with the elastic clip when plugged in to realize the reliable insertion of the pin jack and make the pin difficult to escape from the jack . However, the contact elasticity between the pin and the socket is insufficient.

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 better holding power and elasticity.

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

An electrical connector includes a sleeve and a contact spring housed in the sleeve. The contact spring includes a first end ring, a second end ring, and a plurality of terminals located between the first and second end rings. The first reed and the second reed, the two ends of the first reed are respectively integrally connected to the first and second end rings, one end of the second reed is connected to the first end ring, and the other end is not It is connected to the second end ring and abuts against the inner wall surface of the sleeve.

Compared with the conventional technology, this creation has the following effects: the contact spring of this creation is stably held in the sleeve and has better elasticity.

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

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

Please refer to the second figure. The sleeve 10 is cylindrical and is provided with a receiving cavity 101 for receiving the contact spring 20. The receiving cavity 101 penetrates through one end of the sleeve 10 and is open, while the other end of the sleeve 10 is closed.

The contact spring 20 includes a first end ring 21, a second end ring 22, and a plurality of first reeds 23 and second reeds 24 located between the first and second end rings 21 and 22. The two ends of the first leaf spring 23 are respectively integrally connected to the first and second end rings 21 and 22 to prevent the contact spring 20 from being severely deformed after multiple insertions and withdrawals. One end of the second reed 24 is connected to the first end ring 21, and the other end is not connected to the second end ring 22 and abuts against the inner wall surface 102 of the sleeve 10, thereby forming an independent structure. The second leaf spring 24 is bent outwardly adjacent to the second end ring 22 so as to be separated from the second end ring 22 by a distance.

The first and second reeds 23 and 24 are evenly arranged at intervals between the first and second end rings 21 and 22. All the reeds have a structure that is gradually bent inward from both ends to the middle, forming a contact portion 20A located in the middle and in a contracted shape. The contact portion 20A electrically abuts the mating terminal 200 to stably transmit a large current. Referring to the fourth figure, the mating terminal 200 is accommodated in the contact spring 20, the contact portion 20A evenly abuts on the outer peripheral surface of the mating terminal, and the mating terminal 200 does not exceed the second end ring 22 after mating.

The second leaf spring 24 is reversely bent near the second end ring 22 to form a supporting portion 241. The supporting portions 241 are independent of each other and elastically abut on the inner wall surface 102 of the sleeve 10 to provide reliable elastic force for the contact spring 20. The supporting portion 241 does not extend beyond the second end ring 22. The supporting portion 241 has a contact surface that abuts the inner wall surface 102 of the sleeve, and the contact surface is a circular arc surface, which is beneficial to provide a smooth hand feeling during the insertion and removal process.

Referring to the fourth figure, the first and second end rings 21, 22 are attached to the inner wall surface 102 of the receiving cavity 101, the first end ring is fixed at the opening of the receiving cavity 101, and the second end ring 22 is fixed on the innermost side of the sleeve , The two end rings 21, 22 can stably hold the contact spring 20 to prevent it from loosening or position shifting after multiple insertions and removals.

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-mentioned are only the preferred embodiments of this creation, and the scope of this creation is not limited to the foregoing embodiments. Anyone who is familiar with the techniques of this case makes equivalent modifications or changes based on the spirit of this creation. Should be covered in the scope of the following patent applications.
