[0003] The Chinese patent with the patent number 201010614586.2 discloses a jack contact used in an electrical connector, which realizes reliable contact with the plug post through the structure that the middle part of the grid bar bends inwards, so as to achieve the function of electrical conduction.

[0004] However, this kind of jack contact has the following deficiencies: the jack structures in each connection hole are basically the same, resulting in basically the same electrical conduction time for all plug posts and all jacks. For the use scenario where there are requirements for the sequence of electrical conduction when the male socket and the female socket are plugged and unplugged and different plug posts and jacks are electrically plugged in, it is obviously impossible to meet the requirements. Summary of the Invention

[0005] The utility model provides a jack structure and an electrical connector for the problems of the prior art, which can accelerate the electrical conduction time with the plug post during the insertion process of the plug post to meet the requirements.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

The first connection part is connected to the main body, and the plurality of first grid bars are evenly distributed between the first connection part and the second connection part. The two ends of each first grid bar are respectively connected to the first connection part and the second connection part.

[0009] Still further, the first contact part has a first contact hole, and the middle part of the first grid bar bends towards the first contact hole to form a first bending part.

[0010] Still further, the inner diameter of the first connection part is not less than that of the second connection part.

[0011] Further, the main body includes a first connecting ring, a second connecting ring, and a plurality of second grid bars. The second connecting ring is connected to the first contact portion. The plurality of second grid bars are evenly distributed between the first connecting ring and the second connecting ring. Two ends of each second grid bar are respectively connected to the first connecting ring and the second connecting ring.

[0012] Furthermore, the main body has a second contact hole. The middle part of each second grid bar bends towards the second contact hole to form a second bending portion.

[0013] Furthermore, the inner diameter of the first connecting ring is equal to the inner diameter of the second connecting ring.

[0014] Further, the main body and the first contact portion are integrally formed. The contact member is installed in the hole sleeve by press-fitting.

[0015] The present utility model also provides an electrical connector, which includes a body, a first connection hole and a second connection hole both arranged on the body.

Detailed Embodiments

[0021] 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.

[0022] Embodiment 1

[0023] If Figure 1 and Figure 2 As shown, this embodiment provides a jack structure, including a hole sleeve 1 and a contact member 2 arranged in the hole sleeve 1, the hole sleeve 1 has an opening 3, the contact member 2 includes a main body 4 and a first contact portion 5, the first contact portion 5 is arranged at one end of the main body 4 close to the opening 3, and the inner diameter of the main body 4 is larger than the inner diameter of the first contact portion 5.

[0024] That is, in the prior art, you can refer to the Chinese patent No. 201010614586.2. When the external plug is inserted, the plug contacts the grid on its surface. Since the grid is formed by bending metal and has a certain elasticity, it is ensured that the grid always has elastic force to restore the deformation after being stretched by the plug, thereby ensuring reliable contact between the plug and the grid to ensure electrical conduction.

[0025] Compared with the prior art, the present invention adds a first contact portion 5, and the inner diameter of the first contact portion 5 is smaller than the inner diameter of the main body 4, so that when the external plug is inserted into the present invention, the plug first contacts the first contact portion 5 to achieve electrical conduction; the purpose of the subsequent plug being fully inserted into the present invention is to position and increase the contact area with the present invention, thereby ensuring the electrical conduction effect.

[0026] In this embodiment, the first contact portion 5 includes a first connection portion 51, a second connection portion 52 and a plurality of first bars 53. The first connection portion 51 is connected to the main body 4. The plurality of first bars 53 are evenly distributed between the first connection portion 51 and the second connection portion 52. The two ends of the first bars 53 are respectively connected to the first connection portion 51 and the second connection portion 52.

[0027] Specifically, the first contact portion 5 has a first contact hole 54, and the middle portion of the first grid bar 53 is bent toward the first contact hole 54 to form a first bent portion 55.

[0028] That is, the cross-sectional shape of the first grid bar 53 is an arc, and its first curved portion 55 is used to achieve first contact with the plug post; since the first grid bar 53 is made of metal, it has a certain resilience, so that after the plug post forces the first grid bar 53 to deform outward, the first grid bar 53 always has a tendency to recover the deformation and exert elastic force on the plug post, ensuring the reliability of the contact between the first grid bar 53 and the plug post.

[0029] Specifically, the inner diameter of the first connecting portion 51 is not less than the inner diameter of the second connecting portion 52.

[0030] ​​In this embodiment, the main body 4 includes a first connecting ring 41, a second connecting ring 42, and a plurality of second grid bars 43. The second connecting ring 42 is connected to the first contact part 5. The plurality of second grid bars 43 are evenly distributed between the first connecting ring 41 and the second connecting ring 42. Both ends of the second grid bar 43 are respectively connected to the first connecting ring 41 and the second connecting ring 42.

[0031] Specifically, the main body 4 has a second contact hole 44, and the middle part of the second grid bar 43 bends towards the second contact hole 44 to form a second bending part 45.

[0032] The specific shape of the main body 4 is basically the same as that of the prior art, and will not be elaborated here. It should be emphasized that the second connecting ring 42 and the first connecting part 51 are connected to each other, and the two form a shape similar to a funnel, making the interior of the present utility model smoother and avoiding scratching the plug post.

[0033] Specifically, the inner diameter of the first connecting ring 41 is equal to the inner diameter of the second connecting ring 42.

[0034] Specifically, the main body 4 and the first contact part 5 are integrally formed, and the contact member 2 is installed in the hole sleeve 1 by press-fitting. That is, the contact member 2 itself is formed by stamping and winding, so as to ensure the stability and reliability of the connection between the main body 4 and the first contact member 2.

[0035] Embodiment 2

[0036] As Figure 3 shown, this embodiment provides an electrical connector, including a main body 6, a first connecting hole 7 and a second connecting hole 8 both arranged on the main body 6. The number of the first connecting holes 7 and the number of the second connecting holes 8 are at least one respectively. The second connecting hole 8 includes the jack structure described in Embodiment 1.

[0037] In this embodiment, only the second connecting hole 8 has the jack structure of Embodiment 1. That is, on the premise that the shapes of all the plug posts of the male seat cooperating with this embodiment are basically the same, the plug posts inserted into the second connecting hole 8 can achieve electrical conduction faster, and there is a difference in the electrical conduction time of the plug posts inserted into the second connecting hole 8, so as to meet some usage scenarios with special requirements for plugging and unplugging electrical conduction.

[0038] The above description is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention is disclosed above as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content as equivalent embodiments of equivalent changes, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the present invention shall fall within the scope of the technical solution of the present invention.
