Detailed Implementation

[0024] See Figures 1 to 3 A preferred embodiment of the present invention provides a terminal block bus device, which includes at least a housing 100 and at least one latching assembly 200 disposed on the housing 100. The terminal block bus device of the present invention may further include a socket 300 for insertion into the housing 100, and the housing 100 and the socket 300 may be locked and fixed by the latching assembly 200.

[0025] In this embodiment, the housing 100 is preferably rectangular and flat. The interior of the housing 100 is used to accommodate a circuit board (not shown) for a terminal block. The housing 100 has a mating side 101, and at least one groove 102 perpendicular to the mating side 101 is provided inside the housing 100. In this embodiment, a groove 102 is respectively provided at both ends of the mating side 101. The pair of grooves 102 are symmetrical in construction and have the same function. Only one groove 102 is described as an example below, and the present invention does not limit the number of grooves 102. Specifically, the housing 100 includes a box portion 110 and a cover plate 120 for closing the box portion 110, and the groove 102 is formed within the box portion 110.

[0026] See Figure 2 The latching assembly 200 is housed within the housing portion 110. In this embodiment, each slide groove 102 is respectively configured with a latching assembly 200. The pair of latching assemblies 200 are symmetrical in construction and have the same function. The following description uses only one slide groove 102 as an example, and the present invention does not limit the number of latching assemblies 200. Specifically, the latching assembly 200 is as follows: Figure 3 The diagram shows a synchronized actuator 210 and a locking pin 220. (See attached image.) Figures 2 to 5 In this embodiment, the actuator 210 is disposed in the slide groove 102 and is movable along the slide groove 102 as follows: Figure 7 A release position as shown and as Figure 8The actuating member 210 has an actuating slope set 212 between the release position and the locking position. The locking pin 220 is rotatably arranged in the housing 100 with the central axis of the locking pin 220 as the rotation axis, and the locking pin 220 is arranged corresponding to one end of the slide groove 102. One end of the locking pin 220 is movably connected to the actuating member 210, and the other end of the locking pin 220 extends out of the housing 100 from the connecting side 101 and is provided with a barb 221 on at least one side. The side of the locking pin 220 is provided with a key 222, and the key 222 abuts against the actuating slope set 212 to make the actuating member 210 and the locking pin 220 interact. Therefore, when the actuating member 210 linearly moves between the release position and the locking position along the slide groove 102, the actuating member 210 can push the locking pin 220 to rotate by the actuating slope set 212. Preferably, the side wall of the locking pin 220 is provided with a limiting flange 223, which is clamped into the inner wall of the slide groove 102 in the form of interference, thus allowing the locking pin 220 to rotate; once the actuating slope set 212 pushes the key 222 along the longitudinal direction of the locking pin 220, the limiting flange 223 can be stopped on the inner wall of the slide groove 102 to prevent the locking pin 220 from falling off the housing 100.

[0027] Referring to Figures 3 to 5 The actuating slope set 212 includes a release slope 212a and a locking slope 212b arranged opposite to each other, and the key 222 is arranged between the release slope 212a and the locking slope 212b. The release slope 212a and the locking slope 212b are respectively a spiral slope, the release slope 212a is arranged away from the barb 221, the locking slope 212b is arranged towards the barb 221, and the release slope 212a and the locking slope 212b are respectively used to abut against the two sides of the key 222.

[0028] Referring to Figure 1 and Figure 6 The housing 100 is inserted into the socket 300 with the connecting side 101 thereof, and at least one lock hole 301 is provided in the bottom of the socket 300 corresponding to the barb 221. Preferably, the bottom of the socket 300 can be provided with an electrical connector (not shown in the figure) for connecting to the aforementioned circuit board. Referring to Figures 6 to 7 When the actuating member 210 is in the release position, the barb 221 can pass through the lock hole 301 to allow the housing 100 to be inserted or removed. Referring to Figures 8 to 9 When the housing 100 is inserted into the socket 300 and the actuating member 210 is in the locking position, the barb 221 hooks the inner edge of the lock hole 301 to fix the housing 100 to the socket 300.

[0029] Referring to Figures 7 to 8 The user pushes the actuating member 210 from the release position as shown in Figure 7 to the barb 221 to the locking position as shown in Figure 8In the shown locking position, during the pushing process, the locking slope 212b moves along the longitudinal direction of the locking pin 220, the key 222 abuts against the locking slope 212b and moves along the locking slope 212b, thereby rotating the locking pin 220, and further rotating the barb 221 to hook the inner edge of the locking hole 301. Figure 8 In the shown locking position, during the pushing process, the locking slope 212b moves along the longitudinal direction of the locking pin 220, the key 222 abuts against the locking slope 212b and moves along the locking slope 212b, thereby rotating the locking pin 220, and further rotating the barb 221 to hook the inner edge of the locking hole 301. Figure 7 In the shown releasing position, during the pushing process, the releasing slope 212a moves along the longitudinal direction of the locking pin 220, the key 222 abuts against the releasing slope 212a and moves along the releasing slope 212a, thereby rotating the locking pin 220, and further rotating the barb 221 to unhook the inner edge of the locking hole 301.

[0030] Referring to Figure 2 In the embodiment, the housing 100 is provided with a positioning structure 113, and the actuating member 210 is provided with a buckling structure 213. When the actuating member 210 moves to the shown releasing position or the shown locking position, the buckling structure 213 can correspondingly buckle the positioning structure 113 to position the actuating member 210 at the releasing position or the locking position. Referring to Figure 7 Figure 8 In particular, the positioning structure 113 includes a pair of buckling grooves 113a / 113b respectively corresponding to the releasing position and the locking position, and the buckling structure 213 is a clamping hook, and when the actuating member 210 moves to the releasing position or the locking position, the buckling structure 213 can buckle one of the buckling grooves 113a / 113b corresponding thereto. However, the positioning structure 113 and the buckling structure 213 of the present application are not limited to the foregoing embodiment. In the embodiment, the actuating member 210 can be provided with a pull handle 214, and the pull handle 214 protrudes from the housing 100 to push the actuating member 210. Figure 2 Figures 6 to 9 In the embodiment, at least one elastic member 230 can be arranged in the housing 100, and the elastic member 230 abuts against the inner wall of the housing 100 and the locking pin 220, and thereby can push the barb 221 towards the housing 100. Therefore, when the barb 221 hooks the inner edge of the locking hole 301, it can be forced to tightly fix the housing 100 in the socket 300 by the elastic member 230 cooperating with the barb 221.

[0031] In the embodiment, at least one elastic member 230 can be arranged in the housing 100, and the elastic member 230 abuts against the inner wall of the housing 100 and the locking pin 220, and thereby can push the barb 221 towards the housing 100. Therefore, when the barb 221 hooks the inner edge of the locking hole 301, it can be forced to tightly fix the housing 100 in the socket 300 by the elastic member 230 cooperating with the barb 221.

[0032] In summary, the terminal block busbar device of the present application converts the linear movement of the actuating member 210 into the rotation of the locking pin 220 by the actuating slope group 212 pushing the key 222, to drive the barb 221 to hook the locking hole 301, and reversely rotate to release the socket 300, which is buckled firmly and easily released.
