[0011] Preferably, a connecting plate is provided at the bottom of the connecting terminal, and the connecting plate is fixedly connected to the bottom plate by bolts.

[0012] Compared with the prior art, the utility model is beneficial in that:

[0013] 1. It adopts a double spring structure of tension spring and compression spring. One group of springs acts on the connecting rod, and the other group of springs acts on the pressure plate, so that the pressure plate can be pressed by two groups of springs at the same time, ensuring that the pressure plate will not fall off, greatly improving stability;

[0014] 2. After the wire connection ring is installed on the raised wall, the connecting rod can be inserted into the through hole of the connecting terminal, thereby preventing the wire connection ring from falling off. At the same time, it can be pressed by the pressing plate to achieve the connection of multiple wire connection rings;

DETAILED DESCRIPTION

[0018] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0019] It should be noted that in the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. Terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1 As shown, a boltless terminal block comprises a base plate 1 and a connecting terminal 2, wherein the connecting terminal 2 is fixed on the base plate 1; a connecting terminal through hole 201 is provided on the connecting terminal 2, and a protruding wall 202 extends upward from the outer periphery of the connecting terminal through hole 201; a pressing plate 3 is provided above the connecting terminal 2, and a fixing plate 4 is provided above the pressing plate 3; a pressing plate through hole 301 is provided on the pressing plate 3, and a connecting rod 5 is provided in the pressing plate through hole 301, and a fixing cap 6 is provided at one end of the connecting rod 5, and the other end passes through the fixing plate 4 and the pressing plate 3 from top to bottom in sequence and is inserted into the connecting terminal through hole 201; a tension spring 7 is provided between the fixing cap 6 and the fixing plate 4, and the tension spring provides tension, and a compression spring 8 is provided on the connecting rod between the fixing plate 4 and the pressing plate 3, and the compression spring provides restoring force.

[0022] like Figure 1 As shown, one group of connecting rods does not show the compression spring and the tension spring; a limit plate 501 is provided on the connecting rod 5 between the fixed plate 4 and the pressure plate 3, and the limit plate 501 is circular, and the diameter of the limit plate 501 is larger than the diameter of the connecting terminal through hole 201 and smaller than the diameter of the compression spring 8 and the fixed plate through hole 401; the diameter of the compression spring 8 is larger than the diameter of the fixed plate through hole 401.

[0023] like Figure 1 As shown, the fixing cap 6 is threadedly connected to the connecting rod 5; one end of the tension spring is fixed to the fixing cap by welding. After the fixing cap is connected to the connecting rod, the other end of the tension spring is fixed to the fixing plate by electric welding or other connection methods to achieve the fixation of both ends of the tension spring.

[0024] like Figure 1 As shown, the two ends of the tension spring 7 are fixedly connected to the fixing cap 6 and the fixing plate 4 respectively, ensuring that when the connecting rod is lifted upward, a pulling force can be formed between the fixing cap and the fixing plate. After the external force is lost, the connecting rod can move downward through the pulling force of the spring, and then drive the pressure plate downward through the limit plate, so that the pressure plate can be subjected to the pressure of the two groups of springs; the compression spring only needs to be placed on the connecting rod between the fixing plate and the pressure plate.

[0025] like Figure 1As shown, the outer diameter of the protruding wall 202 is smaller than the diameter of the pressing plate through hole 301, ensuring that when the pressing plate moves downward under the force of the spring, the pressing plate can pass through the protruding wall and contact the wire connecting ring, thereby pressing the wire connecting ring.

[0026] like Figure 1 As shown, the pressing plate 3 is provided with a lifting handle 302 extending outward, and the pressing plate can be driven to move up and down by the lifting handle, so that the operator can operate it conveniently and quickly.

[0027] like Figure 1 As shown, a connecting plate 203 is provided at the bottom of the connecting terminal 2, and the connecting plate is fixedly connected to the bottom plate by bolts. The connecting terminal is fixed to the bottom plate by the connecting plate, which is convenient for later maintenance and installation.

[0028] The working principle of the utility model is described as follows: when in use, lift the pressure plate upward, lift the connecting rod upward behind the limit plate on the top of the pressure plate, then install the wire connecting ring on the raised wall, then lower the pressure plate, and the tension spring and compression spring provide restoring force to press the pressure plate and the connecting ring tightly, avoiding bolt installation, which is convenient, quick and efficient.

[0029] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
