[0042] The embodiment of the present application discloses a quick connection terminal.

[0043] See also Figures 1 to 3 , an embodiment of a quick connection terminal provided in the embodiments of the present application includes:

[0044] The main housing 2 , the movable pressing member 1 and the elastic member 3 .

[0045] An active cavity 21 is provided on the top of the main housing 2 .

[0046] One end of the movable pressing piece 1 is movably inserted into the movable concave cavity 21 and is confined in the movable concave cavity 21. It can be understood that one end of the movable pressing piece 1 can move within a certain range of movement in the movable concave cavity 21 and will not escape from the movable concave cavity 21 to meet the pressing activity requirements, and at the same time, it can also protect the elastic member 3 to prevent the elastic member 3 from being damaged by excessive squeezing. In order to better achieve insertion fit, the top edge of the movable concave cavity 21 is provided with a concave cavity edge guide angle 28, and correspondingly, the outer edge of one end of the movable pressing piece 1 is provided with a pressing piece outer edge guide angle 15. The design of the guide angle is used to achieve a guiding effect, and at the same time, it can improve the smoothness of the fit between the movable pressing piece 1 and the movable concave cavity 21, thereby improving the user experience.

[0047] The existing quick-connection terminals have a pressing terminal with an externally wrapped cylindrical structure. Due to space limitations, the cylindrical structure cannot be made stronger. Once the product accidentally falls during use, it is easy to cause the quick-connection terminal to deform, and then cause the terminal to lose its quick-connection function. In this application, the main housing 2 is designed as a cylindrical structure with a movable cavity 21, and the movable pressing piece 1 is a columnar structure that is nested with the main housing 2. This design makes it easy to thicken the main housing 2, and use the main housing 2 to protect the movable pressing piece 1, thereby improving the overall structural strength, thereby improving the reliability of anti-falling, making it less prone to damage and more stable in use.

[0048] The elastic member 3 is disposed in the movable cavity 21 , and one end of the elastic member 3 contacts and abuts against the movable pressing member 1 , and the other end of the elastic member 3 contacts and abuts against the main housing 2 , so as to provide elastic force for the movable pressing member 1 to return to its original position.

[0049] The main shell 2 is provided with a first wiring hole 22 connected to the movable concave cavity 21, and the movable pressure piece 1 is provided with a second wiring hole 11 that can cooperate with the first wiring hole 22. The cable can be inserted by pressing the movable pressure piece 1 until the first wiring hole 22 is completely aligned with the second wiring hole 11, and then the movable pressure piece 1 is released, and the elastic effect of the elastic piece 3 can be used to make the first wiring port and the second wiring hole 11 staggered to a certain extent, so as to apply a clamping force to the inserted cable, thereby completing the quick wiring, and pressing again until the first wiring hole 22 is completely aligned with the second wiring hole 11, the cable can be taken out. In the present application, the number of the first wiring holes 22 can be multiple, and the corresponding number of the second wiring holes 11 is also multiple, one-to-one corresponding.

[0050] The quick-connect terminal designed in the present application has a sliding fit between the movable pressure piece 1 and the main shell 2, which is nested with each other and has a stable structure. The elastic piece 3 is built into the movable cavity 21, realizing a hidden installation, avoiding the problem of easy entry of external foreign matter, and effectively improving the stability of use.

[0051] The above is an embodiment of a quick connection terminal provided in the embodiment of the present application. The following is an embodiment of a quick connection terminal provided in the embodiment of the present application. For details, please refer to Figures 1 to 3 .

[0052] Based on the solution of the above embodiment 1:

[0053] Furthermore, a first limit sliding portion 4 is provided on the main shell 2, and a second limit sliding portion 12 is provided on the movable pressure piece 1, which is limitedly and slidingly connected to the first limit sliding portion 4. The cooperation between the first limit sliding portion 4 and the second limit sliding portion 12 is utilized to realize the sliding setting of the movable pressure piece 1 within a certain sliding range.

[0054] Furthermore, the first position-limiting sliding part 4 can be a column structure, such as a pin shaft, a pin, etc., and the main shell 2 is provided with a plug hole 24 that is connected to the movable cavity 21 and for the first position-limiting sliding part 4 to be inserted.

[0055] The second limit sliding part 12 is a groove structure, and one end of the first limit sliding part 4 extends into the second limit sliding part 12 through the insertion hole 24 and is connected to the second limit sliding part 12 in a limit sliding manner. The insertion hole 24 is used to fix the first limit sliding part 4, and one end of the first limit sliding part 4 extending into the movable concave cavity 21 is slidably matched with the second limit sliding part 12 in a strip-shaped groove structure. The second limit sliding part 12 provides a sliding stroke limit to ensure that the movable pressing piece 1 can move within the stroke.

[0056] Of course, the design can also be the other way around, with the first limiting sliding portion 4 being a groove structure, and the movable pressing piece 1 being provided with a socket 24, and the corresponding second limiting sliding portion 12 being a column structure, thereby achieving a limiting sliding connection, without specific limitation.

[0057] The number of the first limiting sliding parts 4 in the present application can be multiple and distributed in a circle, and the number of the corresponding second limiting sliding parts 12 can also be multiple and matched one by one.

[0058] Furthermore, a first position-limiting connection portion 13 which is position-limitingly connected to one end of the elastic member 3 is provided on one end of the movable pressing member 1 .

[0059] And / or, a second limiting connection portion 23 which is limitatively connected to the other end of the elastic member 3 is provided in the active cavity 21 .

[0060] By providing the first position limiting connection portion 13 and / or the second position limiting connection portion 23 , the elastic member 3 can be better limited to ensure the elastic effect of the elastic member 3 .

[0061] Furthermore, the first position-limiting connection part 13 can be a groove structure for one end of the elastic member 3 to extend into. In order to better allow the elastic member 3 to extend into, the bottom edge of the first position-limiting connection part 13 is provided with a pressure piece inner edge guide angle 14. In this design, the second position-limiting connection part 23 can also be a groove structure without limitation.

[0062] Further, taking the elastic member 3 as a compression spring as an example, the second position-limiting connection portion 23 can be designed as a protruding structure, arranged at the bottom of the movable cavity 21, and extending into the other end of the elastic member 3. In order to better extend into the elastic member 3, the outer edge of one end of the second position-limiting connection portion 23 is provided with a connection edge guide angle 231.

[0063] Of course, the elastic member 3 in the present application may also be an elastic metal sheet, or be made of a slender coiled metal wire, without limitation.

[0064] Furthermore, a retaining groove 25 is provided at the bottom of the main housing 2. The retaining groove 25 may be multiple in number and is a cutting groove structure. The purpose is to utilize the limiting effect of the cutting groove to lock the main housing 2 so that it is fixed and cannot rotate.

[0065] Furthermore, for the convenience of connection, a connecting column 27 is provided at the bottom of the main housing 2, and a threaded structure 271 is provided on the connecting column 27, that is, a threaded column structure. The outer edge of the connecting column 27 away from the main housing 2 is provided with a column head edge guide angle 272 for edge plug-in fit.

[0066] In order to improve the sealing effect, a sealing groove 26 is provided on the connection column 27 near the main housing 2 , and a sealing ring 7 is provided on the sealing groove 26 .

[0067] The connecting column 27 can be fixedly installed by using the threaded structure 271, for example, it can be installed on a fixed carrier with a threaded hole.

[0068] Furthermore, if Figure 1 As shown, a nut 8 threadably matched with the threaded structure 271 may be further provided. After the connecting column 27 passes through the corresponding fixed carrier, the nut 8 is put on the passed part, and then the nut 8 is rotated until the nut 8 contacts and abuts against the fixed carrier, thereby completing the installation and fixation of the connecting column 27 on the fixed carrier. Of course, a gasket 9 may be further provided so that it is located between the nut 8 and the fixed carrier to enhance the connection reliability, wherein the gasket 9 may be a spring gasket.

[0069] Furthermore, a pressing flange 5 is provided on the other end of the movable pressing piece 1 extending out of the movable concave cavity 21. The diameter of the pressing flange 5 is larger than that of the movable pressing piece 1 to provide convenience for pressing. The pressing flange 5 can be integrally connected or integrally formed with the movable pressing piece 1 without limitation.

[0070] In order to improve safety, an insulating cap 6 is mounted on the pressure-actuated flange 5, which is specifically made of insulating adhesive materials such as rubber. The insulating cap 6 and the pressure-actuated flange 5 can be assembled together by assembly or in-mold molding without limitation.

[0071] A transition slope 51 connected to the movable pressing piece 1 is provided at the bottom of the pressing flange 5 , and the insulating cap 6 covers and extends to the transition slope 51 to better cooperate with the pressing flange 5 .

[0072] Traditionally, to prevent hands from touching the metal surface of the terminal, the outer ring of the terminal is wrapped with easily damaged materials such as heat shrink tubing. However, after a period of use, the heat shrink tubing will fall off or warp and deform, thereby losing the anti-electric shock function. The insulating cap 6 design adopted in this application has a firm structure and is not easy to fall off, which effectively plays the role of insulation protection.

[0073] In addition, the various guide angle designs involved in this application can be rounded corners or chamfered corners without limitation.

[0074] The above is a detailed introduction to a quick connection terminal provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as limiting the present application.
