Description

Electrical connector

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

Chinese utility model patent CN202633582U announced a high-current double crown belt jack, including: jack body, the jack body is provided with two crown springs, respectively, an inner crown spring and an outer crown spring, the outer crown spring is superimposed on the inner crown The outer layer of the spring, the ports of the inner crown spring and the outer crown spring are respectively provided with an inner crown band and an outer crown band, the outer crown band is arranged on the outer layer of the inner crown band, and a sheath is arranged on the outer layer of the jack body. Through the above method, the high-current double crown strap jack of this creation can increase the number of contacts when the jack is in mating contact with the pin, increase the contact area and contact pressure between the crown strap and the jack body, and reduce the contact of the contact couple. Resistance, increase the current carrying capacity of the contact couple, reduce the heat generation of the connector, reduce the temperature of the system, reduce the energy loss of the system, and be able to connect high-current power transmission lines. The contact parts of the inner and outer crown springs are located on different virtual circles.

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 includes: a contact spring formed by nesting an inner crown spring and an outer crown spring, the inner crown spring includes a plurality of inner reeds, the outer crown spring includes a plurality of outer reeds, the inner and outer The reeds are gradually bent inwardly from both ends to form a contact part located in the middle; and a sleeve for accommodating the contact spring; wherein a plurality of the inner and outer reeds are arranged at intervals so that the contact parts of the two are located on the same virtual circle on.

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. This creation discloses an electrical connector 100 for transmitting large current, which includes a sleeve 10 and a contact spring 2 housed in the sleeve 10. As shown in the fifth figure, the inner wall 102 of the sleeve 10 is provided with a step portion 103 where the contact spring 2 is accommodated, and the outer end ring 221 of the contact spring 2 abuts the step portion 103 to perform a limiting effect.

Referring to the third to fifth figures, the contact spring 2 is formed by nesting an inner crown spring 21 and an outer crown spring 22 inside and outside, and the inner and outer crown springs 21 and 22 are cylindrical structures. The inner coronal spring 21 includes a plurality of inner reeds 210, and the outer coronal spring 22 includes a plurality of outer reeds 220. The inner and outer reeds 210 and 220 are gradually bent inward from both ends to form a contact portion 20 in the middle. The plurality of inner and outer reeds 210 and 220 are arranged at intervals, so that the contact portions 20 of the two are located on the same virtual circle. The fourth figure is clearly visible. With this arrangement, more contact parts 20 are provided, and all the contact parts form a parallel circuit, which can be used to transmit a larger current. The inner and outer reeds are arranged staggered and spaced apart from each other. The starting point of the inward bending of the inner reed 210 is inside the outer reed 220, and the innermost contact part 20 of the inner and outer reeds 210 and 220 is located on the same virtual circle (see Figure 4), so the inward bending of the inner reed 210 is smaller than the inward bending of the outer reed 220.

The inner crown spring 21 includes a pair of inner end rings 211, the two ends of the plurality of inner leaf springs 210 are connected to the inner end ring 211, the outer crown spring 22 includes an outer end ring 221, and the two ends of the plurality of outer leaf springs 220 are connected to the outer end. The ring 221 and the inner end ring 211 are attached to the inner side of the outer end ring 221 and fixed together by laser. In other embodiments, it is also possible to provide a stepped portion inside the outer end ring to resist the inner end ring to prevent displacement.

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.
