Description

Technical Field

[0001] The utility model relates to the technical field of electrical connectors, and in particular to a socket structure that increases the contact area between a spring and a plug post. Background Technology

[0002] In the plug for new energy, the socket of the female socket must have a socket structure, and the socket structure is mainly composed of a hole sleeve and a contact piece. The contact piece is formed by winding a spring sheet into a hollow ring structure, and then twisting the two ends of the ring structure in reverse. The reverse twisting action is mainly used to make the grid of the spring sheet into an oblique shape and concave, so as to increase the reliability of contact with the external plug.

[0003] The function of the grid bar is mainly to achieve contact with the plug post. The grid bar itself has elasticity due to the material characteristics, so it always has the force to restore deformation when it is stretched by the plug post to ensure reliable contact with the plug post to ensure the effect of electrical connection between the male socket and the female socket. However, the structure of the existing spring sheet is usually as disclosed in Chinese patent CN202121609477.1, that is, the grid bar and the connecting parts at both ends are arranged vertically. The contact piece achieved by this structure has a small contact area between the grid bar and the plug post, which can easily lead to poor contact between the two due to external factors. SUMMARY OF THE INVENTION

[0004] Aiming at the problems of the prior art, the utility model provides a socket structure that increases the contact area between the spring and the plug post, which can increase the contact area with the external plug post, thereby ensuring reliable contact with the plug post.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model provides a socket structure for increasing the contact area between a spring and a plug post, comprising a hole sleeve and a contact piece pressed into the hole sleeve, the contact piece is made of a spring, the spring comprises a first connecting portion, a second connecting portion and a plurality of bars, the two ends of the bars are respectively connected to the first connecting portion and the second connecting portion, and adjacent bars are arranged at intervals; an acute angle is formed between the bars and the first connecting portion, and the angle of the acute angle is 12-18°.

[0007] Furthermore, the first connection part, the plurality of bars, and the second connection part are integrally formed by a punching process.

[0008] Furthermore, the first connecting portion is provided with a first inclined surface and a second inclined surface at both ends, the shape of the first inclined surface is the same as the shape of the second inclined surface, and the first inclined surface and the second inclined surface are used to abut against each other and be welded after the spring piece is formed into a contact piece.

[0009] Further, third inclined surfaces and fourth inclined surfaces are respectively arranged at both ends of the second connecting portion. The shapes of the third inclined surface and the fourth inclined surface are the same, and the third inclined surface and the fourth inclined surface are used to abut and be welded to each other after the reed is formed into a contact member.

[0010] Further, arc-shaped structures are respectively formed on both sides of the grid bar in contact with the first connecting portion and on both sides of the grid bar in contact with the second connecting portion.

[0011] Further, the first connecting portion and the second connecting portion are parallel to each other.

[0012] Advantages of the present utility model: By setting the acute angle between the grid bar and the first connecting portion to be 12-18°, the torsional forming of the grid bar is greater after the reed is formed into a contact member, thereby increasing the contact area between the grid bar and the external plug post to ensure the electrical transmission effect.

[0016] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model. The present utility model will be described in detail below with reference to the drawings.

[0017] As Figure 1 and Figure 2 shown, a jack structure for increasing the contact area between a reed and a plug post provided by the present utility model includes a hole sleeve and a contact member 2 press-fitted (not shown in the figure) into the hole sleeve. The contact member 2 is made of a reed 3. The reed 3 includes a first connecting portion 4, a second connecting portion 5, and a plurality of grid bars 6. Both ends of the grid bar 6 are respectively connected to the first connecting portion 4 and the second connecting portion 5, and adjacent grid bars 6 are arranged at intervals; an acute angle is formed between the grid bar 6 and the first connecting portion 4, and the angle of the acute angle is 12-18°.

[0018] In actual use, the hole sleeve has a conventional structure, so it will not be elaborated and shown in this embodiment; the acute angle between the grid bar 6 and the first connecting part 4 is preferably 15±0.1°, which can ensure the stable connection between the grid bar 6 and the first connecting part 4 and the second connecting part 5 respectively, and avoid separation; compared with the prior art, in the present utility model, the grid bar 6 is arranged at an acute angle, that is, the grid bar 6 of the present utility model is longer than the grid bar 6 of the prior art. After the reed 3 is formed into the contact 2, the grid bar 6 not only covers a larger area, but also the surface of the grid bar 6 facing the inside of the contact 2 is the surface with the largest area (that is, the front and back sides of the grid bar 6), rather than the connection between the side surface and the front / rear surface of the grid bar 6 in the prior art. Therefore, the contact area between the contact 2 and the external plug can be further increased to ensure the stable electrical transmission.

[0019] In this embodiment, the first connecting part 4, the multiple grid bars 6, and the second connecting part 5 are integrally formed by a punching process, and the first connecting part 4 and the second connecting part 5 are parallel to each other. That is, the reed 3 is an integral structure, which can ensure the reliable contact between the grid bar 6 and the first connecting part 4 and between the grid bar 6 and the second connecting part 5, so that the three will not be separated due to external force.

[0020] In this embodiment, the two ends of the first connecting part 4 are respectively provided with a first inclined surface 7 and a second inclined surface 8. The shape of the first inclined surface 7 is the same as that of the second inclined surface 8. The first inclined surface 7 and the second inclined surface 8 are used to abut and be welded to each other after the reed 3 is formed into the contact 2.

[0021] That is, when the reed 3 is formed into the contact 2, the first inclined surface 7 and the second inclined surface 8 abut for positioning, and then the first inclined surface 7 and the second inclined surface 8 are fixed by welding, so that the structure of the contact 2 is stable and the contact 2 is prevented from returning to the shape of the reed 3 due to internal stress.

[0022] In this embodiment, the two ends of the second connecting part 5 are respectively provided with a third inclined surface 9 and a fourth inclined surface 10. The shape of the third inclined surface 9 is the same as that of the fourth inclined surface 10. The third inclined surface 9 and the fourth inclined surface 10 are used to abut and be welded to each other after the reed 3 is formed into the contact 2.

[0023] In this embodiment, arc-shaped structures 11 are respectively formed on the two sides of the grid bar 6 in contact with the first connecting part 4 and on the two sides of the grid bar 6 in contact with the second connecting part 5. The setting of the arc-shaped structures 11 can prevent the grid bar 6 from scratching the plug when it contacts the external plug, so that the plug can still be used reliably after multiple insertions and extractions.

[0024] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model is disclosed above in the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, when making some changes or modifications using the above-disclosed technical content into equivalent embodiments of equivalent changes, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the present utility model shall fall within the scope of the technical solution of the present utility model.
