Description

Electrical connector

[ technical field ] A method for producing a semiconductor device

The present invention relates to an electrical connector, and more particularly to an electrical connector with a contact spring.

[ background of the invention ]

Chinese utility model patent CN202633582U discloses a jack is taken to two crowns of heavy current, include: the jack body is provided with two crown springs which are respectively an inner crown spring and an outer crown spring, the outer crown springs are superposed on the outer layer of the inner crown springs, the port parts of the inner crown springs and the outer crown springs are respectively provided with an inner crown belt and an outer crown belt, the outer crown belts are arranged on the outer layer of the inner crown belts, and the outer layer of the jack body is provided with a sheath. In this way, the utility model discloses a contact quantity when big current double crown area jack can increase jack and contact pin cooperation contact increases the contact area and the contact positive pressure of crown area and jack body, reduces the contact resistance of contact idol, and the current-carrying capacity of increase contact idol reduces the calorific capacity of connector, has reduced the temperature of system, reduces the energy loss of system, can carry out the connection of heavy current power transmission line. The contact portions of the inner and outer crown springs are located on different virtual circumferences.

It is therefore desirable to design an improved electrical connector that overcomes the above-mentioned deficiencies.

[ Utility model ] content

The utility model discloses the technical problem that will solve lies in: an electrical connector is provided having more contact points.

In order to solve the above problem, the utility model discloses following technical scheme can be adopted:

an electric connector comprises a sleeve and a contact spring accommodated in the sleeve, wherein the contact spring is formed by nesting an inner crown spring and an outer crown spring, the inner crown spring comprises a plurality of inner spring leaves, the outer crown spring comprises a plurality of outer spring leaves, the inner spring leaves and the outer spring leaves are gradually bent inwards from two ends to form a contact part positioned in the middle, and the inner spring leaves and the outer spring leaves are arranged at intervals to enable the contact part to be positioned on the same virtual circumference.

Compared with the prior art, the utility model discloses a contact spring's contact point is more to transmit the heavy current.

Electrical connector 100 sleeve 10

Inner wall 102 of containing cavity 101

Step part 103

Contact spring 2 inner crown spring 21

Inner reed 210 inner end ring 211

Outer crown spring 22 and outer leaf 220

Outer end ring 221 contact portion 20

The following detailed description of the invention will be further described in conjunction with the above-identified drawings.

[ detailed description ] embodiments

Referring to fig. 1 to 2, the present invention discloses an electrical connector 100 for transmitting large current, which includes a sleeve 10 and a contact spring 2 accommodated in the sleeve 10. As shown in fig. 5, the inner wall 102 of the sleeve 10 is provided with a step 103 for accommodating the contact spring 2, and the outer end ring 221 of the contact spring 2 abuts against the step 103 to perform a stopper function.

Referring to fig. 3 to 5, the contact spring 2 is formed by internally and externally nesting an inner crown spring 21 and an outer crown spring 22, and the inner and

outer crown springs

21 and 22 have cylindrical structures. The inner spring crown 21 comprises a plurality of inner spring leaves 210, the outer spring crown 22 comprises a plurality of outer spring leaves 220, and the inner spring leaves 210 and the outer spring leaves 220 are gradually bent inwards from two ends to form the contact part 20 in the middle. Several of the inner and

outer leaves

210, 220 are spaced apart such that the contact portions 20 of both are located on the same virtual circumference, as best seen in figure 4. With this arrangement, more contacts 20 are provided, all of which form a parallel circuit for carrying a larger current. The inner and outer spring leaves are alternately arranged, the starting point of the inward bending of the inner spring leaf 210 is located inward compared with the outer spring leaf 220, and the innermost contacting parts 20 of the inner and

outer spring leaves

210, 220 are located on the same virtual circumference (see fig. 4), so the inward bending radian of the inner spring leaf 210 is smaller than the inward bending radian of the outer spring leaf 220.

The inner crown spring 21 comprises an inner end ring 211, two ends of a plurality of inner reeds 210 are connected to the inner end ring 211, the outer crown spring 22 comprises an outer end ring 221, two ends of a plurality of outer reeds 220 are connected to the outer end ring 221, and the inner end ring 211 is attached to the inner side of the outer end ring 221 and fixed together through laser. In other embodiments, a step portion may be provided inside the outer end ring to abut against the inner end ring to prevent displacement thereof.

The above-described embodiments are presently preferred, but not necessarily all, embodiments of the invention. Any equivalent changes taken by those skilled in the art from the technical solution of the present invention through reading the specification of the present invention are covered by the claims of the present invention.
