• Die Steckerkomponente 200 und die Steckerkomponente 300 können zu einer Verdrahtungsklemme kombiniert und verbunden werden.

With reference to The second embodiment of the utility model is based on the previous embodiment, which differs from the previous one in that:

• The connector component 200 and the connector component 300 can be combined and connected to form a wiring terminal.

The socket component 200 includes sockets 201, which has a socket 201a which is a circular hole. There is a sliding groove 201b extending radially on the inside of the bases 201a, and there are two symmetrically arranged sliding grooves 201b. There are two sliding blocks 202 within the sliding groove 201b, which can also slide radially within the sliding groove 201b. Connector component 300, including connector 301, which has a connection column 301a. The connection column 301a is cylindrical and can be connected to socket 201a in a gap shape and can also be inserted into socket 201a. There is an annular groove 301b on the side of the connecting column 301a along the circumference, and the width of the annular groove 301b should be larger than the axial width of the slider 202; The connection column 301a can be embedded in the 201a, and there is a first line 302 embedded in the connection column 301a. The first line 302 forms a first contact 302a at the end of the connection column 301a, and there is a second line 203 within the socket 201. When the socket assembly 200 and the plug assembly 300 are connected, the second line 203 is connected to the first contact 302a, to form a path.

The end of the slider 202a near the center of the base 201a has a trapezoidal shaft 202a, which is an isosceles trapezoidal shape. That is, the end of the slider 202a near the center of the base 201a forms two slopes, namely the two slopes of the trapezoidal shaft 202a. The height of the trapezoidal shaft 202a is smaller than the depth of the annular groove 301b. When the trapezoidal shaft 202a is embedded in the annular groove 301b, the two sides of the slider 202 connected to the inclined plane of the trapezoidal head 202a can limit the axial displacement of the connecting column 301a when in contact with the side of the annular groove 301b.

The two sides of the slider 202 are equipped with a round table 202b, and the sliding groove 201b has a strip-shaped end groove 201c on the side. The rotary table 202b is embedded in the end groove 201c. The round table 202b moves within the limiting slot 201c, which is a long strip-shaped slot. The movable range of the round table 202b and the trapezoidal table 202a is: When the slider 202 moves away from the center of the carriage 201a, the trapezoidal table 202a can move into the slot 201b. At this point, one side of the trapezoidal convex 202a is against the peripheral surface of the annular groove 301b, and a part of the rectangular shape of 202 is inside the annular groove 301b because the height of the trapezoidal convex 202a is smaller than the depth of the annular groove 301b, which means that the trapezoidal convex 202a is completely embedded in the annular groove 301b.

A first elastic member 207 is disposed between the side 202 and the carriage 201b away from the center of the bushing 201a, and the first elastic member 207 is a compression spring.

Arranged in 201a is a sliding disk 204, which is in the form of a disk and can move along an axis within the jack 201a. A connecting pin 204a is disposed on the side of the sliding disk 204, and a waist-shaped hole 201d extending axially is disposed inside the jack 201a. The connecting pin 204a is embedded in the waist-shaped hole 201d, and the sliding disk 204 can move only within the range of the waist-shaped hole 201d. The end of 204a is connected to a pin 204b, and the end of 204b is provided with a tip 204c to form a wedge. The side of the slider 202 in near the connecting pin 204a is provided with a groove 202c; When the tip 204c is inserted into the slot 202c, the keystone boss 202a does not fully extend into the slot 201a. When the tip 204c is released from the slot 202c, the keystone boss 202a and the slider portion 202c extend into the base 201a.

There is a second elastic component 205 between the sliding disk 204 and the bottom of the socket 201a. The second elastic component 205 is a compression spring, and there is a through hole 204d in the center of the sliding disk 204. The through hole 204d is slidably connected to an adjustment column 206 , and there is a third elastic component 210 between the adjustment column 206 and the bottom of the socket 201a. The third elastic component 210 is a compression spring. Note that one end of the third elastic member 210 of the adjustment column 206 may have a concave hole, and one end of the third elastic member 210 is fixedly connected to the concave hole. When the connecting column 301a is inserted into the jack 201a to To press the adjustment column 206, the annular groove 301b is clamped in place with the trapezoidal head 202a, and one end of 301a is pressed precisely against the bottom surface of the jack 201a. Preferably, 203 is embedded in the adjustment column 206 and forms a second contact 203a on the end face of the adjustment column 206 near the first contact 302a. When 301a is embedded in socket 201a, the second contact 203a contacts the first contact 302a to form a path.

Furthermore, there is a circular projection 206a on the surface of the adjusting column 206 between the sliding disk 204 and the bottom of the jack 201a. When the adjusting column 206 moves toward the outer jack 201a, the circular projection 206a can limit the moving distance of the adjusting column 206.

There is a circular groove 204e on the inner side of the through hole 204d, a sliding groove 206b on the adjustment column 206, and two evenly spaced sliding grooves 206b. There is a sliding block 208 inside 206b, which is a rectangular trapezoid structure. The sharp end of the sliding block 208 can expand out of the sliding groove 206b and into the circular groove 204e. 206b is also a rectangular trapezoid shape and passes through the outside of the adjustment column 206, so that the sliding block 208 can only move radially inside the sliding groove 206b; Between the sliding block 208 and the sliding groove 206b, there is a fourth elastic member 209. The fourth elastic component 209 is a spring. When the wiring terminal is not connected, the sharp end of the slide block 208 extends from the slide groove 206b and into the annular groove 204e, and the annular projection 206a contacts the end face of the slide disk 204. When 301a enters the socket 201a, its end comes into contact with the adjustment column 206 and presses the adjustment column 206 to compress the third elastic member 210. Since one end of the slide block 208 is embedded in the annular groove 204e, the adjustment column 206 also drives the slide disk 204 to move, and the installation position of the slide block 208 is adjusted to its short side near the connecting column 301a.

At one end near the plug 301, there is an annular deep groove 206c which intersects with the slide groove 206b and passes through an end surface of the slide groove 206b, that is, the inclined surface of the slide groove 206b intersects with the annular deep groove 206c. At the end of the connecting column 301a, there is an annular long groove 301c which extends axially, and inside the annular long groove 301c, there is an annular cylinder 303. On the side of the plug 301, there is a strip through hole 301d which intersects with the annular long groove 301c, and at the end of the annular cylinder 303, there is an adjusting rod 303a which is inside the strip through hole 301d. A fifth elastic member 304 is arranged between 303a and the end of the strip through hole 301d near the bases 201, and the fifth elastic member 304 is a spring. When the adjusting rod 303a is operated to move 303 axially toward the adjusting column 206, one end of 303 enters the annular deep groove 206c and collides with the inclined surface of the sliding block 208, thereby pushing the sliding block 208 to contract toward the adjusting column 206.

In this embodiment, the principle is as follows: in the initial state, under the action of the first elastic member 207, the second elastic member 205, the third elastic member 210 and the fourth elastic member 209, 204 are located near the opening of the socket 201a, the tip 204c is embedded in the slot 202c to limit the slider 202 to move toward the center of the socket 201a, and the trapezoidal boss 202a is partly in the socket 201a and partly in the socket 201b; During the process of connecting the column 301a into the socket 201a, the end of 301a first contacts the side slope of the trapezoidal boss 202a and presses the slider 202 to contract inward of the slide groove 201b. The contact of 301a with the adjustment column 206 and presses the adjustment column 206 to compress the third elastic member 210. Since one end of the sliding block 208 is embedded in the annular groove 204e, the adjusting column 206 also drives the sliding disk 204 to move, causing the tip 204c to detach from the groove 202c. When the connecting column 301a pushes the adjusting column 206 to touch the bottom of the socket 201a, the annular groove 301b passes over the slider 202 and coincides with the sliding groove 201b. Under the action of 207, the part of the slider 202 and the trapezoidal head 202a enter the annular groove 301b as a whole to form a clamp. As shown in point Ader 7 shown, the two sides of the slider 202 contact with the sides of the annular groove 301b for clamping and limit the axial displacement of the connecting column 301a; When it is necessary to disconnect the wiring terminals, operate the adjusting rod 303a to move the annular cylinder 303 along the axial direction and toward the adjusting column 206. When one end of the annular cylinder 303 enters the annular deep groove 206c and collides with the inclined surface of 208, and then push the slide block 208 to contract and release inward from the annular groove 204e. At this time, the slide disk 204 moves under the action of the second elastic member 205 in the direction near the connecting column 301a 204c, thereby being embedded in the groove 202c. The inclined plane of the tip 204c drives the slider 202 toward the sliding groove 201b, as shown in position B of the 9 shown. At this point, the part of 202a enters the sliding groove 201b. When the plug 301 is pulled outward, the connecting column 301a and the annular groove 301b detach from the socket 201a along the inclined plane of the trapezoidal head 202a. After detachment, the part of 202a rebounds back into the socket 201a. This utility model is applied to DCS to quickly connect and disconnect the wiring terminals of the trunking.
