Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents the selected embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0034] Embodiment
[0035] In conjunction with Figures 1 to 7 As shown in the drawings, the present embodiment provides a trigger type terminal, which comprises an insulation shell 1, an electrically conductive body 2, a clamping spring 5 and a button 6 installed in the insulation shell 1, wherein the insulation shell 1 is provided with a first clamping part 7; the button 6 is provided with a second clamping part 8 and a first trigger part 9; the clamping spring 5 is integrally formed, and two ends thereof are respectively formed with a clamping section 3 and a trigger section 4, and the trigger section 4 is provided with a second trigger part 10;
[0036] Wherein, the button 6 will push the clamping section 3 to perform elastic rotation after being pressed, and the button 6 can perform forward flipping under the action of the elasticity of the clamping section 3 after being pressed to a certain stroke, so as to make the second clamping part 8 clamped on the first clamping part 7, thereby making the clamping section 3 in a compressed trigger-ready state, and at this time, the clamping section 3 and the electrically conductive body 2 form a wire insertion space for the wire 14;
[0037] When the conductor 14 presses the trigger section 4, the second trigger part 10 pushes the first trigger part 9 to make the button 6 reverse, and the second clamping part 8 is released from the clamping with the first clamping part 7, so as to release the clamping section 3 and clamp the conductor 14.
[0038] Specifically, in the embodiment, the insulating shell 1 has a wire insertion hole 11 and a button hole 12. The conductive body 2 is arranged at the bottom of the insulating shell 1, and the two ends are bent upwards to form a conductive part 13 capable of electrically contacting the conductor 14. The wire clamping spring 5 is integrally formed, and the two ends are respectively formed with a clamping section 3 and a trigger section 4. The trigger section 4 is provided with a second trigger part 10.
[0039] As shown in Figures 3 to 7 The insulating shell 1 is provided with two protrusions 16, and the wire clamping spring 5 is positioned on the insulating shell 1 by the cooperation of the two spring bows 17 on the wire clamping spring 5 and the protrusions 16. The first clamping part 7 is a first step surface arranged on the button 6 hole of the insulating shell 1. The second clamping part 8 is a second step surface arranged on the button 6. The third step surface 15 is arranged above the first step surface on the button 6 hole, and the side forms a fulcrum for the button 6 to reverse. The third step surface 15 is provided with a protruding first arc-shaped side wall 22 above the third step surface 15. The second arc-shaped side wall 23 is arranged above the second step surface and matched with the first arc-shaped side wall 22. The arrangement of the arc-shaped side wall increases the clamping area between the third step surface 15 and the second step surface, so as to limit the upward movement of the button 6 under the elastic force of the clamping section 3 when the clamping of the first clamping part 7 and the second clamping part 8 is released, and avoid the button 6 from falling out of the button hole 12. The arrangement of the arc-shaped side wall increases the contact guiding area of the side wall of the button 6 and the side wall of the button hole 12, so as to realize better guiding effect. The arrangement of the arc-shaped side wall can reduce the lateral displacement of the button 6, and further ensure the stability of the clamping of the first clamping part 7 and the second clamping part 8.
[0040] In the embodiment, as shown in Figure 7 The button 6 includes an acting part 18 acting on the clamping section 3, and an extension part 19 connected to the acting part 18 and extending to the trigger section 4. The second clamping part 8 is arranged on the acting part 18, and the first trigger part 9 is arranged on the extension part 19. The extension part 19 is in the form of a sheet and movably attached to the wall surface of the insulating shell 1.
[0041] As shown in Figure 2 The left side and Figure 8As shown, under the action of external force on the button 6, the action portion 18 presses down the clamping section 3 to make the clamping section 3 elastically turn over in the direction of the pressing down (i.e. the clamping section 3 elastically contracts around the convex portion 16), and when the button 6 is pressed down to a certain stroke (i.e. the second step surface exceeds the first step surface), the pressing down force is removed, at this time, the button 6 is positively turned over along the fulcrum under the action of the elastic force of the clamping section 3, so that the second step surface is clamped on the first step surface, the button 6 is locked in the vertical direction, so that the clamping section 3 is in the compressed state of being ready to be triggered, and the clamping section 3 and the conducting portion 13 of the conductive body 2 form a wire insertion space for the wire 14. That is, the clamping section 3 is in an elastically compressed state under the limiting of the button 6 to form a wire insertion space between the clamping section 3 and the conducting portion 13.
[0042] It should be noted that the size of the button hole 12 is at least greater than the width of the button 6 along the turning over direction, so that the button 6 has a certain turning over space. The positive turning over refers to the turning over of the button 6 along the fulcrum to make the second step surface close to the first step surface.
[0043] As shown in the left side of FIG. 1, the button 6 is in the state of being ready to be triggered, and the clamping section 3 is in the compressed state. Figure 2 As shown in the right side of FIG. 1, the button 6 is in the state of being triggered, and the clamping section 3 is in the released state. Figure 9 As shown, when the wire 14 presses down the triggering section 4, the triggering section 4 is elastically turned over downward, the second triggering portion 10 pushes the first triggering portion 9, the button 6 is forced to move downward and reversely turn over along the fulcrum, so that the second clamping portion 8 moves away from the first clamping portion 7 and is thus unclamped; and the action portion 18 moves upward under the action of the elastic force of the clamping section 3, until the second step surface is clamped on the third step surface 15, so that the button 6 is limited; at this time, the clamping section 3 is in the released state, i.e. the clamping section 3 approaches the conducting portion 13 to clamp the wire 14.
[0044] It should be noted that the reverse turning over refers to the turning over of the button 6 along the fulcrum to make the second step surface turn over away from the first step surface.
[0045] In the embodiment, the first triggering portion 9 has a first circular arc-shaped triggering surface; the second triggering portion 10 is formed by bending the body portion of the wire clamping spring 5 to form a second circular arc-shaped triggering surface matched with the first circular arc-shaped triggering surface, and in this embodiment, the second triggering portion 10 is symmetrically arranged on both sides of the triggering section of the wire clamping spring 5, so that the wire clamping spring 5 can be arranged on both sides of the wire terminal symmetrically (such as Figure 2The arc-shaped triggering surface can make the second triggering part 10 push the first triggering part 9 more smoothly. Of course, in other embodiments, the second triggering part 10 can also be directly a step surface or a convex part opposite to the first arc-shaped triggering surface, which can push the first triggering part 9, and the specific limitation is not made here.
[0046] Preferably, a third clamping part 20 is further arranged on the insulating shell 1, and a fourth clamping part 21 matched with the third clamping part 20 is arranged on the extending part 19. The fourth clamping part 21 can assist clamping to ensure that the key 6 is clamped on the insulating shell 1 stably.
[0047] The utility model discloses a trigger type wiring terminal, which is limited and kept by the key 6 and the insulating shell 1, so that the clamping section 3 is in an elastic compression state. The clamping section 3 and the triggering section 4 are not clamped with each other. The wire clamping spring 5 is integrally formed, and only a second triggering part 10 needs to be bent and processed on the body. Compared with the prior art, the clamping section and the triggering section do not need to be provided with clamping parts, and an additional triggering part is not needed. The structure is simple and easy to process. The key 6 is used to limit and clamp the clamping section 3 in the elastic compression state. This mode can effectively avoid the situation that the clamping section 3 is automatically unlocked and released when the wiring terminal falls during transportation or before use.
