[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0024] Example 1
[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the track terminal with a handle includes an insulating body 1, a spring 4, and a handle 2. The insulating body is a shell formed of insulating material. The configuration of the insulating body can be selected according to requirements. In this example, only the side-opening plate type is shown. The insulating body 1 has a cavity 10 formed inside for the installation of the spring, and the insulating body 1 has a socket 15 formed on it for the insertion of wires, etc. The socket 15 communicates with the cavity 10. The position of the socket can be selected according to requirements, preferably as follows: Figure 1 As shown, a socket 15 is formed on the side of the insulating body 1.
[0026] In this example, the shrapnel is shown in a common configuration, as follows: Figure 3 As shown, the spring 4 includes a contact part 41, a clamping part 42, and a curved part 43 connecting the two. The whole is U-shaped. The contact part 41 is connected to a portion of the conductive terminal 3 located in the chamber 10. The C-shaped curved part 43 is sleeved on a column formed on the wall of the chamber 10. In the initial state, the clamping part 42 in the spring is in the path of the wire or the like being inserted into the socket 15, thereby blocking the socket.
[0027] In this example, the overall configuration of handle 2 will still be shown using a common configuration, as detailed below. Figure 4 , Figure 5As shown, the handle, as a whole, includes a body 21 and a protrusion 22 extending outward from the side at the end of the body 21. The end of the body 21 containing the protrusion extends outward from a mounting hole 11 formed in the cavity wall of the chamber 10, exposed outside the insulating body. For example, a groove or hole may be formed in the top wall of the chamber 10, serving as the mounting hole 11. The protrusion 22 extending from the mounting hole 11 is exposed outside the top surface of the insulating body 1. The handle body 21, located within the chamber 10, is rotatably connected to the cavity wall of the chamber 10. A push block 25 is formed on the body 21 within the chamber. The clamping part 42 is located on the moving path of the push block 25. During use, force is applied to the protrusion with a screwdriver or finger to rotate the handle, simultaneously pushing the clamping part with the push block to release it from the plug hole. After resetting, the clamping part engages with the corresponding conductive terminal to clamp the wire; this is the engagement between the handle and the clamping part. The handle configuration can be selected from the market according to requirements, and the specific configuration of the body can also be selected according to requirements, such as a V-shape, or... Figure 4 , Figure 5 The strip shape shown.
[0028] Regarding the pivotal connection between the handle body and the cavity wall, a pivot portion 24 is added to the body 21, through which the handle body is pivotally connected to the cavity wall. For the pivot portion, a pivot hole type is used, specifically as follows: Figure 1 , Figure 4 , Figure 5 As shown, a ring is formed at the other end of the main body 21, serving as a pivot 24. A shaft is formed on the wall of the chamber 10, extending into the ring opening of the pivot 24 to form a rotatable connection. During use, the restoring elastic force of the clamping part continuously presses on the pivot and shaft, easily causing damage to the shaft or pivot structure within a short time. To improve structural stability, in this example, a guide arc surface 14 is formed on the chamber wall corresponding to the direction of movement of the clamping part 42 under the elastic force (i.e., the direction of the clamping part's elastic restoring force). Figure 1 , Figure 2 As shown, the peripheral wall of the pivot part 24 is located in the groove formed by the guide arc surface 14. The guide arc surface supports the pivot part in the direction of the clamping part's reset movement and simultaneously supports the shaft at the cavity wall, which helps to improve structural stability.
[0029] Of course, the pivot can also be axial and directly inserted into the hole formed in the cavity wall to form a rotating connection. Similarly, the pivot is supported by a guide arc surface, which helps to improve the structural stability.
[0030] In this example, a protrusion 23 is provided on the protrusion 22, such as Figure 1 , Figure 4 As shown, a protrusion 23 is formed protruding outward at the bottom surface of the protrusion 22, and a groove 12 is formed along the moving path of the protrusion 23 at the insulating body 1 below the protrusion 22. Figure 1 , Figure 3As shown, in this example, the groove 12 is formed by recessing the end face of the hole on one side of the mounting hole 11. The end of the protrusion 23 is in the groove 12 and slides with the groove 12. When the handle is rotated, the protrusion moves along the groove. The groove walls on both sides of the groove restrict the protrusion from disengaging from both sides, which helps to reduce the phenomenon of the handle falling off the insulating body.
[0031] There are no restrictions on the shape of the bump; you can choose prisms, cylinders, spheres, T-shapes, etc., depending on your needs.
[0032] To facilitate handle installation, a notch 13 is formed at the end side wall of the slide groove 12 in this example. The size of the notch is sufficient for the protrusion to enter and exit, such as... Figure 1 As shown, during assembly, the protrusion 23 can enter the slide groove 12 through the notch 13, or during disassembly, it can leave the slide groove through the notch. Figure 4 , Figure 5 , Figure 1 As shown, the contact part of the spring 4 needs to be connected to the longitudinal part of the conductive terminal 3. In order to avoid the conductive terminal restricting the rotation of the handle, a clearance groove is formed on the side of the handle body in this example. When the handle is rotated to the position where the socket is unlocked, the end of the longitudinal part of the conductive terminal is in the clearance groove, which facilitates the layout and installation.
[0033] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
