In the embodiment, two sliding grooves 102 are respectively disposed at two ends of the corresponding abutting side 101, the pair of sliding grooves 102 are symmetrical in structure and have the same efficacy, which will be illustrated by only one sliding groove 102, and the utility model is not limited to the number of sliding grooves 102. Specifically, the housing 100 includes a box portion 110 and a cover 120 closing the box portion 110, and the sliding slot 102 is formed in the box portion 110.

Referring to fig. 2, the latch assemblies 200 are accommodated in the box portion 110, in the present embodiment, a latch assembly 200 is respectively disposed in each sliding slot 102, the latch assemblies 200 are symmetrical and have the same function, which will be illustrated by only one sliding slot 102, and the number of the latch assemblies 200 is not limited in the present invention. Specifically, the latch assembly 200 includes an actuating member 210 and a locking pin 220, which are interlocked with each other, as shown in fig. 3. Referring to fig. 2 to 5, in the present embodiment, the actuating member 210 is disposed on the sliding slot 102 and can move along the sliding slot 102 between a releasing position shown in fig. 7 and a locking position shown in fig. 8, and the actuating member 210 has an actuating slope surface set 212. The locking pin 220 is rotatably disposed on the housing 100 with a central axis of the locking pin 220 as a rotation axis, and the locking pin 220 is disposed corresponding to one end of the sliding slot 102, one end of the locking pin 220 movably passes through the actuator 210, and the other end of the locking pin 220 extends from the abutting side 101 to penetrate out of the housing 100 and at least one side thereof is provided with a barb 221. A protruding key 222 is protruded from the side of the locking pin 220, and the protruding key 222 abuts against the actuating slope group 212 to make the actuating piece 210 and the locking pin 220 linked with each other. Therefore, when the actuating member 210 moves linearly along the sliding slot 102 between the release position and the locking position, the actuating member 210 can push the locking pin 220 to rotate by the actuating ramp set 212. Preferably, a limit flange 223 is convexly disposed on a side wall of the locking pin 220, and the limit flange 223 is inserted into an inner wall of the sliding slot 102 in an interference fit manner, thereby allowing the locking pin 220 to rotate along the rotation direction; once the actuation ramp set 212 pushes against the key 222 in the longitudinal direction of the locking pin 220, the stop flange 223 can stop against the inner wall of the sliding slot 102 to prevent the locking pin 220 from falling out of the housing 100.

Referring to fig. 8 to 9, when the housing 100 is inserted into the socket 300 and the actuator 210 is located at the locking position, the barbs 221 hook the inner edge of the locking holes 301 to fix the housing 100 to the socket 300.

Referring to fig. 7 to 8, when the user pushes the actuating member 210 toward the barb 221 from the release position shown in fig. 7 to the locking position shown in fig. 8, the locking slope 212b moves along the longitudinal direction of the locking pin 220 during the pushing process, and the key 222 abuts against the locking slope 212b and moves relatively along the locking slope 212b, so that the locking pin 220 rotates, and the barb 221 is further rotated to hook the inner edge of the locking hole 301. When the user pushes the actuating member 210 away from the barb 221 from the locking position shown in fig. 8 to the releasing position shown in fig. 7, during the pushing process, the releasing slope 212a moves along the longitudinal direction of the locking pin 220, and the key 222 abuts against the releasing slope 212a and moves along the releasing slope 212a relatively, so that the locking pin 220 rotates, and the barb 221 is driven to rotate to disengage from the inner edge of the locking hole 301.

Referring to fig. 2, in the present embodiment, the housing 100 is provided with a positioning structure 113, and the actuating element 210 has a fastening structure 213. When actuator 210 is moved to the release position as shown in FIG. 7 or the lock position as shown in FIG. 8, snap-fit structure 213 can correspondingly snap-fit into locating structure 113 to locate actuator 210 in the release or lock position. Referring to fig. 2 and 6 to 9, in particular, the positioning structure 113 includes a pair of fastening grooves 113a/113b respectively corresponding to the releasing position and the locking position, the fastening structure 213 is a hook, and when the actuator 210 moves to the releasing position or the locking position, the fastening structure 213 can be fastened to one of the fastening grooves 113a/113 b. However, the positioning structure 113 and the fastening structure 213 of the present invention are not limited to the aforementioned embodiments. In this embodiment, the actuator 210 can have a pull handle 214, and the pull handle 214 protrudes out of the housing 100 for the user to push the actuator 210.

In this embodiment, at least one elastic member 230 may be disposed in the housing 100, and the elastic member 230 abuts against the inner wall of the housing 100 and the locking pin 220, respectively, and thereby the barb 221 can be pushed towards the housing 100. Therefore, when the barbs 221 hook the inner edge of the locking hole 301, the elastic member 230 cooperates with the barbs 221 to tightly fix the housing 100 in the socket 300.

In summary, the terminal block bus device of the present invention converts the linear movement of the actuating element 210 into the axial rotation of the locking pin 220 by actuating the ramp group 212 to push the convex key 222 to drive the barb 221 to hook the locking hole 301, so as to lock the housing 100 to the socket 300 or rotate reversely to release the socket 300, which is stable and easy to release.
