[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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] The present invention will be further described below in conjunction with the embodiments.

[0022] Example:

[0023] See attached Figure 1 —Attachment Figure 3 A multifunctional electrical connector for coal machinery includes a body 1, a plurality of wire slots 101 are provided on one side of the body 1, and the wire slots 101 are provided, and the wire 4 is connected to the power supply by inserting the wire slots 101, and a conductive block 106 is fixedly installed in the wire slots 101, and the conductive block 106 supplies power to the wire 4. A cable 107 is fixedly connected to the side of the body 1 away from the wire slots 101, and the cable 107 supplies power to the body 1 as a whole. A plurality of fixed slots 102 are provided on the body 1, and the fixed slots 102 are used to limit the sliding track of the sliding block 203. The fixed slots 102 are provided with a plurality of protective components 2 for dust prevention, and the protective components 2 include a sliding block 203 slidably inserted in the fixed slots 102. When the wire 4 passes through the receiving slot 205, the spring a201 is moved to The sliding block 203 is pushed upward, so that the sliding block 203 has a certain clamping effect on the connected wire 4. The sliding block 203 is provided with a positioning hole 204. By setting the positioning hole 204, it is convenient to connect the wire 4 through the sliding block 203. The sliding block 203 is provided with a storage groove 205. The storage groove 205 is used to fix the position of the dust plug 207 and store the dust plug 207. A spring b206 is fixedly installed in the storage groove 205. By setting the spring b206, when the storage groove 205 and the wire insertion slot 101 are at the same horizontal height, the spring b206 pushes the dust plug 207 out of the storage groove 205, and the end of the spring b206 is fixedly installed with the dust plug 207. The dust plug 207 whose end is located at the wire insertion slot 101 is used to prevent dust from entering the wire insertion slot 101.

[0024] A plurality of movable bins a103 are provided in the body 1, and the movable bins a103 are used to limit the movable range of the base 202. A spring a201 is fixedly installed in the movable bin a103. By setting the spring a201, the spring a201 pushes the sliding block 203 to rise, and supports the storage slot 205 to maintain the same height as the wire insertion slot 101. A base 202 is fixedly installed on the spring a201, and the base 202 is fixedly connected to the sliding block 203. The base 202 is used to limit the rising height of the sliding block 203 to prevent the storage slot 205 from being difficult to maintain the same height as the wire insertion slot 101.

[0025] The locking hole 204 and the storage groove 205 are both provided with a trumpet mouth on the side close to the opening of the wire plug slot 101. The inner diameters of the locking hole 204 and the storage groove 205 are smaller than the diameter of the wire plug slot 101. The diameter of the access wire 4 should be equal to the inner diameter of the locking hole 204. When the access wire 4 passes through the locking hole 204, the dust on the access wire 4 will be scratched by the locking hole 204, separated from the access wire 4, and slide out along the trumpet mouth. The port of the dust plug 207 is also trumpet-shaped. When the sliding block 203 is reset, the dust plug 207 will push out the remaining dust in the wire plug slot 101, thereby preventing dust from polluting the inside of the body 1.

[0026] A movable bin b104 is provided in the body 1, and the movable bin b104 leaves space for the clamping plate 303 to move up and down. Multiple sets of limit blocks 105 are fixedly installed in the movable bin b104. By setting the limit blocks 105, it is beneficial to restrict the clamping plate 303 to avoid excessive clamping of the connected wire 4 and thus damage to the connected wire 4.

[0027] A fixing component 3 is provided on the body 1, which helps to prevent vibration during the use of the device from causing the connected wire 4 to slip out of the wire slot 101. The fixing component 3 includes a limit rod 301 fixedly installed on the limit block 105. The limit rod 301 limits the rotation of the clamping plate 303 along the axis of the two-way threaded rod 302. The two-way threaded rod 302 is rotatably inserted on the limit block 105. The two-way threaded rod 302 controls the lifting and lowering of the clamping plate 303. The limit rod 301 and the two-way threaded rod 302 are both provided with clamping plates 303 on both sides of the limit block 105. The two groups of clamping plates 303 clamp and fix the connected wire 4. The upper end of the two-way threaded rod 302 passes through the body 1 and is fixedly installed with a handle 304. By setting the handle 304, it is convenient to manually and quickly adjust the two-way threaded rod 302. The rotation range of the handle 304 is 0°-90°.

[0028] Working principle: When the access wire 4 is not inserted into the wire slot 101, the spring a201 pushes the sliding block 203 to rise, so that the storage slot 205 and the wire slot 101 are at the same horizontal height, and the spring b206 pushes the end of the dust plug 207 into the wire slot 101, and the dust plug 207 prevents dust from entering the wire slot 101.

[0029] When the incoming wire 4 needs to be connected to the body 1, one hand inserts the incoming wire 4 into the wire slot 101, and the incoming wire 4 pushes the dust plug 207 to squeeze the spring b206 back into the receiving slot 205. The other hand presses down the sliding block 203 to keep the positioning hole 204 and the wire slot 101 at the same height, so that the incoming wire 4 is inserted into and contacts the conductive block 106, and the handle 304 is rotated to control the two sets of clamping plates 303 to clamp the incoming wire 4 through the bidirectional threaded rod 302, thereby achieving the purpose of fixing the incoming wire 4.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
