[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] Example 1

[0050] See also Figure 1 The present embodiment provides a push-type terminal block for connecting wires with terminal rings (not shown). The push-type terminal block includes a base 1, a conductive sheet 2 arranged on the top of the base 1, a fixed plate 3 rotatably arranged above the base 1, a crimping column 4 fixed on the fixed plate 3, a positioning groove 5 arranged on the top of the base 1, and an elastic reset member 6.

[0051] The conductive sheet 2 has a head end and a tail end that are arranged opposite to each other along the length direction, and the tail end of the conductive sheet 2 extends outward along the length direction to extend out of the base 1. The tail end of the conductive sheet 2 can be provided with a pin structure (not shown) to be welded and connected to a circuit board (not shown), or the tail end of the conductive sheet 2 can be welded and connected to the tail end of another conductive sheet 2 to electrically connect the two push-type terminal blocks, so as to realize the connection of two wires with terminal rings. The pin structure is a conventional structure and will not be described in detail here.

[0052] It should be noted that the length direction is Figure 1 As shown by arrow a.

[0053] Specifically, the fixed plate 3 has a pressing end and a clamping end that are arranged opposite to each other along the length direction. The clamping end and the pressing end can rotate synchronously around the rotation axis of the fixed plate 3, and the pressing end is located above the head end of the conductive sheet 2. In this embodiment, the fixed plate 3 can be fixed above the base 1 by a rotating shaft (not shown). Specifically, the rotating shaft can be fixed on the housing of the device that needs to be wired, or an additional plate body is provided for fixing the rotating shaft. For conventional settings, the fixed plate 3 is provided with an axial hole 7 for the rotating shaft to pass through. Among them, the elastic reset member 6 is always held between the base 1 and the pressing end, and is used to restore the pressing end and the clamping end to the initial position.

[0054] The crimping column 4 has a first section 41 and a second section 42 connected to each other. The first section 41 is fixed on the clamping end, the second section 42 faces the base 1, and the second section 42 is configured to be inserted into the terminal ring. The positioning groove 5 is arranged at the top of the base 1 and is located directly below the second section 42. Part of the second section 42 is suitable for being received in the positioning groove 5 to lock the terminal ring. In the height direction, the orthographic projection of the first section 41 does not overlap with the orthographic projection of the positioning groove 5. The first section 41 cooperates with the positioning groove 5 to limit the terminal ring from sliding relative to the second section 42 in the axial direction. In order to improve the structural stability after locking, in this embodiment, the cross-sectional shape of the positioning groove 5 is adapted to the cross-sectional shape of the second section 42.

[0055] The elastic reset member 6 has a first compressed state and a second restored state. In the first state, the pressing end compresses the elastic reset member 6 under the action of external force to approach the base 1, and the clamping end drives the second section 42 to move out of the positioning groove 5 to release the terminal ring. In the second state, the pressing end returns to the initial position under the elastic action of the elastic reset member 6, and the clamping end drives the second section 42 to enter the positioning groove 5 to lock the terminal ring and make the terminal ring contact with the conductive sheet 2.

[0056] In order to improve the connection stability, in this embodiment, the first section 41 and the second section 42 are coaxially arranged, and the diameter of the first section 41 is larger than the diameter of the second section 42. At the same time, in order to ensure that the terminal ring is in stable contact with the conductive sheet 2, the relationship between the length D1 of the second section 42, the depth D2 of the positioning groove 5 and the thickness D3 of the terminal ring is: D1 = D2 + D3. And the diameter of the first section 41 is larger than the inner diameter of the terminal ring.

[0057] When the external force is released, the clamping end returns to the initial position under the action of the elastic reset member 6, and the second section 42 is inserted into the terminal ring and partially extends into the positioning groove 5. Since the length of the second section 42 is equal to the sum of the depth of the positioning groove 5 and the thickness of the terminal ring, the length of the second section 42 extending out of the positioning groove 5 is equal to the thickness of the terminal ring, so that the first section 41 cooperates with the base 1 to press the terminal ring and the conductive sheet 2 together, ensuring the contact between the conductive sheet 2 and the terminal ring, thereby ensuring the effectiveness of the electrical connection.

[0058] In this embodiment, the elastic reset member 6 includes a support column 61 and a spring 62 sleeved on the outside of the support column 61. One end of the spring 62 is fixed on the base 1, and the other end always abuts against the bottom surface of the pressing end. One end of the support column 61 is fixed on the bottom surface of the pressing end, and the other end faces the base 1 and has a distance between it and the base 1.

[0059] In order to ensure that when the pressing end is pressed down, the second section 42 can be removed from the positioning groove 5 and continue to move until enough space is released so that the terminal ring can be removed from the second section 42, the relationship between the distance D4 between the support column 61 and the base 1, the depth D2 of the positioning groove 5 and the thickness D3 of the terminal ring is: D4≥D2+D3.

[0060] Due to the application of the above technical solution, the beneficial effects of the present application compared with the prior art are:

[0061] The push-type terminal block of the present application has a simple overall structure. The operator can easily connect the wire with the terminal ring to the base through a simple pressing operation without using screws or other tools. When the wire needs to be replaced or released, it is only necessary to apply external force to the pressing end. This design simplifies the operating process and improves efficiency.

[0062] At the same time, the design of the elastic return member ensures that the pressing end can quickly and reliably return to its original position after the external force is released, thereby ensuring the stability and reliability of the wiring. Under the action of the elastic return member, the conductive sheet and the wire can be in firm contact, thereby ensuring a good electrical connection.

[0063] In addition, the first section cooperates with the positioning groove to limit the terminal ring from sliding away from the second section in the axial direction, thereby improving the structural stability and safety of use after wiring.
