[0033] Embodiment 1

[0034] This embodiment provides a connector with a simple structure, few parts, easy assembly and low manufacturing cost.

[0035] like Figure 1-Figure 2 As shown, the connector mainly includes a female plug 100, a male plug 200 and an elastic shorting element 300. The female plug 100 includes a female plug core body 110, in which at least two female pins 120 are arranged. The male plug 200 includes a male plug core body 210, in which male pins 220 are arranged to cooperate with the female pins 120, and the male pins 220 and the female pins 120 are arranged one by one; an insulating plug 230 is arranged on the male plug core body 210. The elastic short-circuit element 300 is arranged between the two female pins 120, the first end of the elastic short-circuit element 300 is sleeved with one of the female pins 120, and the second end of the elastic short-circuit element 300 can abut against the other female pin 120; when the female plug 100 and the male plug 200 are plugged into each other, the insulating pin 230 can lift the elastic short-circuit element 300 and cause the elastic short-circuit element 300 to deform so that the second end of the elastic short-circuit element 300 is away from the female pin 120.

[0036] Based on the above design, in this embodiment, two male pins 220 and two female pins 120 are provided, and one elastic short-circuit element 300 is provided as an example for description. The female plug body 110 and the male plug body 210 can be made of ceramic insulating materials or engineering plastics to avoid leakage and improve the safety of the connector. Figure 1 As shown, when the male plug 200 is separated from the female plug 100, the first end of the elastic shorting element 300 is sleeved with one of the female pins 120, and the second end of the elastic shorting element 300 can abut against the other female pin 120, so that the two female pins 120 can be short-circuited, that is, the connector is in a short-circuit state. Figure 2 As shown, when the male plug 200 is plugged into the female plug 100, the insulating pin 230 on the male plug 200 can push up the elastic short-circuit element 300, so that part of the elastic short-circuit element 300 can rotate counterclockwise, so that the second end of the elastic short-circuit element 300 can rotate a certain angle, and then the second end of the elastic short-circuit element 300 can be away from the female pin 120 abutting against it, so that the two female pins 120 can be in an open circuit state. The flexible switching of the short circuit and open circuit states of the connector is achieved by plugging and unplugging the male plug 200 and the female plug 100.

[0037] Compared with the prior art, the connector in this embodiment has a simple structure and is easy to assemble. Only one elastic short-circuit element 300 needs to be connected between every two female pins 120 to achieve the switching between the short-circuit and open-circuit states of the two female pins 120. This can reduce the number of parts of the connector, make the structure simpler, and reduce the manufacturing cost. When the male plug 200 and the female plug 100 in this embodiment are plugged in, the insulating pin 230 on the male plug 200 can push up the elastic short-circuit element 300, so that part of the elastic short-circuit element 300 can rotate counterclockwise, so that the second end of the elastic short-circuit element 300 can rotate a certain angle, and then the second end of the elastic short-circuit element 300 can be away from the female pin 120 abutting against it, so that the two female pins 120 can be in an open circuit state.

[0038] Optionally, the elastic short-circuit element 300 in this embodiment is a sheet metal part with a certain elasticity, thereby increasing the service life of the elastic short-circuit element 300 .

[0039] Optionally, the elastic short-circuit element 300 in this embodiment may be made of copper, aluminum, stainless steel or other metal alloy materials.

[0040] like Figure 1 As shown, in this embodiment, the elastic short-circuit element 300 includes a connecting portion 310 and a short-circuit portion 320, and the connecting portion 310 and the short-circuit portion 320 are integrally formed. One end of the connecting portion 310 is sleeved on one of the female pins 120, thereby improving the stability and reliability of the connection between the connecting portion 310 and one of the female pins 120 and avoiding the phenomenon of loosening and detachment. One end of the short-circuit portion 320 can abut against another female pin 120, and the insulating plug 230 can abut against the short-circuit portion 320. In this way, when the male plug 200 and the female plug 100 are plugged and matched, the insulating plug 230 can abut against the short-circuit portion 320 and push the short-circuit portion 320 up, and the short-circuit portion 320 can rotate counterclockwise by a certain angle, so that the short-circuit portion 320 is away from the female pin 120 abutting against it, so that the two female pins 120 can be in an open circuit state.

[0041] It should be noted that the connection part 310 in this embodiment includes a stretching opening, and the inner diameter of the stretching opening is interference-fitted with the outer diameter of the female pin 120, thereby realizing the sleeve connection between the connection part 310 and the female pin 120. The end size of the stretching opening is smaller than the top size, which can prevent the connection part 310 from falling off, thereby realizing the sleeve connection between the connection part 310 and one of the female pins 120.

[0042] Preferably, the insulating plug 230 abuts against the middle of the short-circuit portion 320, so that the short-circuit portion 320 is evenly stressed, thereby improving the smoothness of switching between the short-circuit and open-circuit states of the connector.

[0043] In another embodiment (not shown in the figure), the insulating pin 230 can also be set on the side of the male pin 220 corresponding to the female pin 120 abutted by the short-circuit portion 320, so that when the male plug 200 and the female plug 100 are connected, the insulating pin 230 can be directly inserted between the short-circuit portion 320 and the female pin 120 abutted by it, thereby improving the stability of the connector switching between the short-circuit and open-circuit states.

[0044] Furthermore, the short-circuit portion 320 and the connecting portion 310 in this embodiment are arranged in a "V-shape", that is, there is a preset angle between the connecting portion 310 and the short-circuit portion 320, and the preset angle is set between 20° and 80°. For example, the preset angle can be set to values ​​such as 20°, 40°, 60°, and 80°. In this way, when the insulating plug 230 pushes the short-circuit portion 320, the short-circuit portion 320 can rotate flexibly, thereby realizing the open circuit state of the two female pins 120. When the preset angle is less than 20°, the short-circuit portion 320 cannot abut against the female pin 120 in a natural state, thereby failing to realize the short circuit of the two female pins 120; when the preset angle is greater than 80°, when the insulating pin pushes the short-circuit portion 320, the rotation angle of the short-circuit portion 320 is small, and there is a high possibility that the short-circuit portion 320 still abuts against the female pin 120, that is, the open circuit state of the two female pins 120 cannot be realized. Therefore, setting the preset angle between 20° and 80° can well overcome the above-mentioned problem and realize flexible switching between the short-circuit and open-circuit states of the connector.

[0045] like Figure 1 As shown, in this embodiment, the insulating plug 230 is disposed between two adjacent male pins 220, and the insulating plug 230 can abut against the middle of the short-circuit portion 320. This can avoid the problem of short-circuiting between the two male pins 220, thereby improving safety. Furthermore, the insulating plug 230 and the male plug core 210 are integrally formed, thereby improving processing efficiency and reducing costs.

[0046] like Figure 1 As shown, in this embodiment, an insulating isolation portion 130 is formed on the female ferrule body 110, and the insulating isolation portion 130 is located between two adjacent female pins 120, so that the two female pins 120 can be prevented from short-circuiting in a natural state. Furthermore, the insulating isolation portion 130 is integrally formed with the female ferrule body 110, which improves processing efficiency and reduces costs.

[0047] Furthermore, the insulating plug 230 and the insulating isolation part 130 are arranged opposite to each other, and a limiting part 140 is protruded from the end of the insulating isolation part 130, and part of the short-circuit part 320 is located on one side of the limiting part 140, and the other part of the short-circuit part 320 is located on the other side of the limiting part 140. In this way, when the insulating plug 230 pushes the short-circuit part 320, the limiting part 140 can play a certain limiting role on the short-circuit part 320, so as to prevent the short-circuit part 320 from rotating too much and getting entangled or even knotted with the connecting part 310, thereby improving the reliability of the rebound of the short-circuit part 320 and extending the service life of the connector. That is to say, when the female plug 100 and the male plug 200 are not plugged in, the short-circuit portion 320 is located on the side of the limiting portion 140 close to the plug hole; when the female plug 100 and the male plug 200 are plugged in, part of the short-circuit portion 320 is located on the side of the limiting portion 140 close to the plug hole, and the other part of the short-circuit portion 320 is located on the side of the limiting portion 140 away from the plug hole.

[0048] like Figure 1 As shown, in this embodiment, the connector further includes a fixing member 400. A mounting hole is provided on the female plug core body 110. The fixing member 400 is inserted into the mounting hole to fix the female pin 120 on the female plug core body 110. The setting of the fixing member 400 can improve the reliability and stability of the connection between the female pin 120 and the female plug core body 110, ensure the accuracy of the plug-in matching between the male pin 220 and the female pin 120, and extend the service life.

[0049] Optionally, the fixing member 400 in this embodiment can be set as a screw, the rod of the screw passes through the mounting hole and is connected to the female pin, the rod of the screw is threadedly connected to the mounting hole, and the head of the screw is placed in the mounting hole. Of course, the operator can also set the fixing member 400 to other parts according to actual needs, which will not be described in detail here.

[0050] like Figure 1 As shown, in this embodiment, a protective cover 150 is further provided in the female ferrule body 110, and the protective cover 150 is connected to the female ferrule body 110 by snapping, and the protective cover 150 is configured to protect the female pin 120. The protective cover 150 can be made of ceramic insulating material or engineering plastic, and is used to protect the female pin 120, reduce the damage to the female pin 120 by foreign matter, and extend the service life.

[0051] Embodiment 2

[0052] like Figure 3-Figure 4As shown, this embodiment provides a connector, which is mainly different from the embodiment 1 in that: the elastic short-circuit element 300 in this embodiment includes a connecting portion 310 and a short-circuit portion 320, wherein the short-circuit portion 320 includes an integrally formed horizontal portion 3202 and an inclined portion 3201, and the end of the inclined portion 3201 away from the horizontal portion 3202 is connected to the connecting portion 310; the insulating pin 230 and the insulating isolation portion 130 are arranged opposite to each other.

[0053] When the female plug 100 and the male plug 200 are not plugged in, along the direction from the female plug 100 to the male plug 200, the projection of the inclined portion 3201 partially overlaps with the projection of the insulating plug 230, and at this time, a first angle is formed between the inclined portion 3201 and the connecting portion 310, and the horizontal portion 3202 abuts against the female pin 120, thereby realizing the short-circuit state of the connector. When the female plug 100 and the male plug 200 are plugged in, the inclined portion 3201 is located on one side of the insulating plug 230, and the horizontal portion 3202 is located between the insulating plug 230 and the insulating isolation portion 130. During the process of inserting the insulating pin 230 into the female plug 100, the insulating pin 230 always abuts against the inclined portion 3201. At this time, the first angle gradually decreases, so that the inclined portion 3201 can drive the horizontal portion 3202 to move toward the direction close to the connecting portion 310. At this time, the horizontal portion 3202 breaks the abutment with the female pin 120, and the connector is in the disconnected (open) state.

[0054] In this embodiment, the arrangement of the inclined portion 3201 enables the short-circuit portion 320 to form a certain space to avoid the plug-in area of ​​the insulating plug 230, so that when the male plug 200 and the female plug 100 are plugged in, the interference between the short-circuit portion 320 and the insulating plug 230 can be reduced, thereby avoiding the phenomenon of permanent deformation and inability to rebound of the elastic short-circuit element 300, improving the stability of the connector and extending its service life.

[0055] Preferably, the connecting portion 310 , the inclined portion 3201 and the horizontal portion 3202 in this embodiment are integrally formed, so as to improve processing efficiency, increase the strength of the elastic short-circuit element 300 , and extend the service life.

[0056] Optionally, the first angle may be set to between 45° and 90°, for example, 45°, 50°, 70°, 90°, and the like.

[0057] The rest of the structure of the connector in this embodiment is the same as that in the first embodiment and will not be described in detail here.

[0058] Obviously, the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
