[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please refer to the attached Figure 1 -Attached Figure 4 An electrical signal acquisition interface comprises a collector body 1, three interfaces 2 are arranged on the right side of the collector body 1, a mounting assembly is arranged on one side of the collector body 1 at the interface 2, the mounting assembly comprises a plug 201 inserted into the inside of the interface 2, a wire 202 is arranged on one side of the plug 201, and limit plates 203 are fixed on both sides of the right side of the collector body 1 near the interface 2, the limit plates 203 are made of iron alloy, two limit plates 203 adjacent to the interface 2 form a group, and three plugs 201 are respectively inserted between the two limit plates 203 of each group.

[0022] In the embodiment, in each group of two limit plates 203, the top and bottom surfaces of the limit plate 203 close to the rear side of the interface 2 are rotatably connected with a protective cover 204, the protective cover 204 is made of iron alloy, and a fixing rod 205 is fixed to one side of the protective cover 204 located on the top surface of the limit plate 203, and the fixing rod 205 is in contact with one side of the plug 201. By setting the limit plate 203, after the plug 201 is plugged into the interface 2, the limit plate 203 can effectively limit the vertical and horizontal directions of the plug 201 to prevent the plug 201 from being moved horizontally or vertically. The force causes the plug 201 to separate from the interface 2. At the same time, the protective cover 204 can also cooperate with the limit plate 203 to protect the plug 201. The fixing rod 205 can effectively prevent the plug 201 from separating from the interface 2 from the rear after the plug 201 is plugged into the interface 2, further increasing the reliability of the connection between the plug 201 and the interface 2. The plugging process of the plug 201 and the interface 2 can be completed with one hand, and the other hand can support the collector body 1, which is convenient for the staff to better plug the plug 201 into the interface 2, and the disassembly process is simple and fast.

[0023] In an embodiment, a first fixing groove 206 is provided on one side of the protective cover 204 close to the plug 201, and an adsorption strip 207 is fixed inside the first fixing groove 206. The adsorption strip 207 is made of a magnetic material, and the adsorption strip 207 is adsorbed to the top surface or bottom surface of the limiting plate 203 close to the front side of the interface 2. By arranging the adsorption strip 207 to be adsorbed to the limiting plate 203, the protective cover 204 and the limiting plate 203 can be made to be more convenient to disassemble.

[0024] In an embodiment, a sponge block 208 is fixed to one side of the protective cover 204 close to the plug 201, and the sponge block 208 is in contact with the top surface or the bottom surface of the plug 201. By using two protective covers 204 and cooperating with the sponge block 208, the gap between the protective cover 204 and the plug 201 can be blocked to prevent dust from entering.

[0025] In the embodiment, a second fixing groove 3 is opened on one side of the fixing rod 205 close to the interface 2, and an adsorption block 301 is fixed inside the second fixing groove 3. The adsorption block 301 is made of a magnet. The adsorption block 301 is adsorbed on one side of the protective cover 204 located on the bottom surface of the limiting plate 203. By setting the adsorption block 301 and the protective cover 204 to be adsorbed, the upper and lower protective covers 204 are connected, so that the protective cover 204 is fixed more tightly.

[0026] In an embodiment, two curved portions are provided on one side of the limit plate 203 close to the plug 201, and the curvature of the inner wall of the curved portion is adapted to the curvature of the corner of the plug 201. By setting the curvature of the inner wall of the curved portion of the limit plate 203 to be adapted to the curvature of the corner of the plug 201, the plug 201 is clamped between the two limit plates 203, and the vertical and horizontal directions of the plug 201 are effectively restricted to prevent the plug 201 from being separated from the interface 2 due to lateral or vertical force on the plug 201.

[0027] Working principle: When in use, the protective cover 204 is turned over 180 degrees to separate the adsorption strip 207 of the protective cover 204 from the limiting plate 203, and then the plug 201 is pinched with the thumb and index finger and inserted between the limiting plates 203 and then connected with the interface 2, and then the protective cover 204 is reset, and the adsorption strip 207 and the limiting plate 203 are re-adsorbed, and the adsorption block 301 is also adsorbed to one side of the protective cover 204. At this time, the two sponge blocks 208 are respectively attached to the top surface or the bottom surface of the plug 201, so as to complete the insertion. The inner wall curvature of the bent portion of the limit plate 203 is adapted to the corner curvature of the plug 201, so that the plug 201 is clamped between the two limit plates 203, and the vertical and horizontal directions of the plug 201 are effectively restricted to prevent the plug 201 from being separated from the interface 2 due to lateral or vertical force. The fixing rod 205 can effectively prevent the plug 201 from being separated from the interface 2 from the rear after the plug 201 is plugged into the interface 2, thereby further increasing the reliability of the connection between the plug 201 and the interface 2.
