[0029] Please see Figures 1-2 In this embodiment of the invention, a connecting terminal 1 is formed by bending a strip in the middle. A left contact 11 protrudes outward from the left side of the connecting terminal 1, and the surface of the left contact 11 is electroplated with a silver layer. A right contact 12 protrudes outward from the right side of the connecting terminal 1, and the surface of the right contact 12 is also electroplated with a silver layer. The area of ​​the left contact 11 is no larger than the area of ​​the left side of the connecting terminal, and the area of ​​the right contact 12 is no larger than the area of ​​the right side of the connecting terminal. A retaining groove 13 is respectively formed on the front and rear ends of the connecting terminal 1. By designing a connecting terminal 1, silver plating is only performed at the contact points of the connecting terminal 1, effectively saving electroplating materials and reducing cost waste. The connecting terminal 1 is made entirely of high-conductivity copper material, which allows for a thinner connecting terminal 1 while still ensuring current carrying capacity.

[0030] Specifically, the left contact 11 and the right contact 12 can be shaped like an outer arc, which is convenient for processing and silver plating.

[0031] Further as Figures 1-2 As shown in the embodiment of this utility model, the left contact 11 is located at the lower middle of the left side, and the right contact 12 is located at the lower middle of the right side.

[0032] Further as Figures 1-2 As shown in the embodiment of this utility model, the bending angle of the connecting terminal 1 is 77°.

[0033] Further as Figures 1-2 As shown in this embodiment of the invention, the surface of the left contact 11 is electroplated with a left silver plating layer with a thickness of 0.381 mm, and the surface of the right contact 12 is electroplated with a right silver plating layer with a thickness of 0.381 mm. The silver plating ensures the conductivity of the contact portion of the connection terminal 1, improving connection stability and signal transmission stability.

[0034] Further as Figures 1-2 As shown in the embodiment of this utility model, the material of the connecting terminal 1 is high-conductivity copper, and the material thickness of the connecting terminal 1 is 0.4mm.

[0035] Further as Figures 1-4 As shown in the embodiment of this utility model, an electric switch 2 including the aforementioned connecting terminal 1 is provided. The electric switch 2 includes a guide shell 21, a first guide post 22, a pressing block 23, and a spring 24. The guide shell 21 has an internal hollow structure. Guide grooves 25 are respectively provided on the left and right sides of the guide shell 21 for slidingly installing the connecting terminal 1. The lower end of the guide groove 25 is provided with a bottom contact 251 for contacting the contact of the connecting terminal 1. The connecting terminal 1 is slidably installed in the guide groove 25. The guide post is installed on the inner bottom surface of the guide shell 21, and the spring 24 is sleeved on the guide post. The pressing block 23 is detachably installed at the bend of the connecting terminal 1. One end of the spring 24 abuts against the inner bottom surface of the guide shell 21, and the other end of the spring 24 abuts against the connecting terminal 1. Specifically, the connection method of the pressing block 23 to the connecting terminal 1 includes, but is not limited to, being snapped into the snap-fit ​​groove 1313, which can ensure that the operator can press the pressing block 23 more stably.

[0036] The operator presses the pressing block 23, causing the connecting terminal 1 to slide towards the bottom contact 251, so that the contacts on both sides of the connecting terminal 1 contact the bottom contact 251 inside the guide shell 21. This pressing method is a point-press type. The first press causes the connecting terminal 1 to contact the bottom contact 251, which can be used to transmit a start signal. The second press connects the connecting terminal 1 to the bottom contact 251, which can be used to transmit a braking signal.

[0037] The connecting terminal 1 is installed in the electric switch 2, and the guide groove 25 is set to guide the connecting terminal 1 to make contact, which ensures the accuracy of contact between the terminals and the current carrying capacity. At the same time, the electric switch 2 is also equipped with a guide post to further provide a good guiding effect for the connecting terminal 1.

[0038] Further as Figures 3-4 As shown in the embodiment of this utility model, the bottom contact 251 is an inner arc shape that corresponds to the contact shape of the connecting terminal 1.

[0039] Further as Figures 3-4 As shown in this embodiment of the invention, guide shell 21 has guide shell terminals 27 on its left and right sides, and the guide shell terminals 27 are electrically connected to the bottom contact 251. The guide shell terminals 27 are used to electrically connect to other electrical components, and the bottom contact 251 can transmit start / stop signals to the guide shell terminals 27, which in turn transmit the signals to other electrical components.

[0040] Further as Figures 3-4As shown in this embodiment of the present invention, the pressing block 23 is further provided with a second guide post 26, which is installed at the lower end of the pressing block 23 and corresponds to the first guide post 22. Specifically, the second guide post 26 and the first guide post 22 are located on the same axis. When the operator presses, the second guide post 26 moves in the opposite direction until it abuts against each other. At this time, the contact at the connecting terminal 1 contacts the contact inside the guide shell 21. Since the spring 24 is compressed when pressed, when the operator releases the pressure on the pressing block 23, the spring 24 will generate elastic force to spring the connecting terminal 1 upward, so that the contact of the connecting terminal 1 disconnects from the contact at the guide shell 21, and the connecting terminal 1 resets.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
