Detailed implementation manners

[0027] The following further describes the present invention in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the specific embodiments cited are not intended to limit the present invention.

[0028] The present invention provides a terminal block device and its latch-type electrical connection plug, as Figure 7As shown, the terminal block device includes a snap-type electrical connection plug (abbreviation: electrical connection plug) 100 and an electrical connection socket 500. The electrical connection plug 100 is pluggably inserted into the electrical connection socket 500 and is electrically conductive with each other after being inserted. Among them, the electrical connection socket 500 is arranged on a circuit board (not shown in the figure), and the electrical connection socket 500 and the circuit board are electrically connected to each other. In addition, the electrical connection socket 500 includes a socket body 5, and a buckle portion 51 is provided or arranged on the socket body 5.

[0029] As Figures 1 to 6 shown, the electrical connection plug 100 includes a housing 1 and a snap handle 3, and the electrical connection plug 100 and the electrical connection socket 500 can be detachably locked together by the snap handle 3.

[0030] The housing 1 can be a single-piece structure (not shown in the figure) and is provided with a guiding groove 15. As Figure 5 shown, the guiding groove 15 is generally V-shaped and is divided into a first section 151 and a second section 152. One ends of the first section 151 and the second section 152 are away from each other, and the other ends of the first section 151 and the second section 152 are close to each other. Specifically, the other ends of the first section 151 and the second section 152 are connected and communicated with each other after being close to each other, so as to form the aforementioned generally V-shaped. In addition, the housing 1 is also provided with a stop portion 113 and is provided with a side opening 123 as Figure 1 shown and an upper opening 16 as Figure 5 shown.

[0031] The housing 1 can also be a two-piece structure (or a structure with two or more pieces) as shown in the figure. The housing 1 belonging to the two-piece structure includes a first outer shell 11 and a second outer shell 12. The first outer shell 11 and the second outer shell 12 can jointly form the aforementioned guiding groove 15 and the aforementioned upper opening 16 after being combined with each other. Specifically, as Figure 2 and Figure 5 shown, a first groove structure 111 is arranged in the first outer shell 11, and a second groove structure 121 is arranged in the second outer shell 12. The first groove structure 111 and the second groove structure 121 can jointly form the guiding groove 15. Among them, the second groove structure 121 includes an upper structural member 1211 and a lower structural member 1212 that are arranged at intervals from each other, and the first groove structure 111 includes another lower structural member (not marked with an element symbol). These three structural members jointly form the guiding groove 15. It should be noted that the aforementioned stop portion 113 is arranged (or formed) inside the first outer shell 11, and the aforementioned side opening 123 is opened on one side of the second outer shell 12.

[0032] The latch handle 3 is disposed through the housing 1 and has a pressing portion 311, a latch body 321, and an acting portion 33. The acting portion 33 is located between the pressing portion 311 and the latch body 321. The acting portion 33 is disposed within the housing 1 and has a first shaft 34 and a second shaft 35 that are spaced apart and arranged side by side. Among them, the first shaft 34 can be guided by the first section 151, and the second shaft 35 can be guided by the second section 152. In addition, the latch handle 3 is further provided with an elastic member 36, and the elastic member 36 elastically acts on the stop portion 113 within the housing 1. It should be noted that the first shaft 34 and the second shaft 35 are obliquely arranged with respect to each other, that is: as Figure 6 and cooperate with Figure 5 shown, the first shaft 34 corresponds to the aforementioned one end adjacent to the first section 151, and the second shaft 35 corresponds to the aforementioned other end adjacent to the second section 152.

[0033] Specifically, as Figure 3 , Figure 4 and Figure 6 shown, the acting portion 33 is an inverted triangular body, and this inverted triangular body necessarily has three vertices. The acting portion 33 extends a linkage arm 31 and a latch arm 32, and the linkage arm 31 and the latch arm 32 are substantially in an L shape. The linkage arm 31 extends out of the aforementioned upper opening 16 and has the aforementioned pressing portion 311 exposed from the upper opening 16. The latch arm 32 extends out of the aforementioned side opening 123 and has the aforementioned latch body 321 exposed from the side opening 123. And the first shaft 34, the second shaft 35, and the latch arm 32 are respectively correspondingly arranged at the three vertices, and the linkage arm 31 and the elastic member 36 are both correspondingly arranged at the same vertex as the first shaft 34. It should be noted that the latch arm 32 and the elastic member 36 extend from the acting portion 33 in two opposite directions, so the latch arm 32 and the elastic member 36 are away from each other, and the acting portion 33 is correspondingly located between the latch arm 32 and the elastic member 36.

[0034] The elastic member 36 can be any member with elastic action. For example, it can be a spring (not shown in the figure) or an elastic arm as shown in the figure. In this embodiment, the elastic arm is taken as an example for description. The elastic member 36 is disposed on the acting portion 33 and one end thereof is correspondingly connected to one of the three vertices as described above, and the other end elastically abuts against the stop portion 113. Since the elastic member 36 obliquely abuts against the stop portion 113, it is easy to be elastically deflected by force.

[0035] The first shaft rod 34 has two end portions 341 and a rod body 342 connected between the two end portions 341. The two end portions 341 protrude from both sides of the acting portion 33, and only a part of the rod body 342 is exposed from a vertex (the first vertex) of the acting portion 33. The second shaft rod 35 also has two end portions 351 and a rod body 352 connected between the two end portions 351. The two end portions 351 also protrude from both sides of the acting portion 33, and only a part of the rod body 352 is exposed from another vertex (the second vertex) of the acting portion 33. Accordingly, the first shaft rod 34 can slide in the first section 151 of the guiding groove 15 with its two end portions 341, or with its rod body 342, or with its two end portions 341 and the rod body 342. Among them, the rod body 342 contacts the first section 151 at its partially exposed part; and the second shaft rod 35 can also slide in the second section 152 of the guiding groove 15 with its two end portions 351, or with its rod body 352, or with its two end portions 351 and the rod body 352. Among them, the rod body 352 also contacts the second section 152 at its partially exposed part.

[0036] Thus, as Figure 5 and Figure 6 shown, when the user presses the pressing portion 311, the linkage arm 31 will drive the acting portion 33. At this time, since the first shaft rod 34 is guided by the first section 151, the linkage arm 31 sinks into the housing 1 in one direction (clockwise direction) (refer to Figure 9 shown), and since the second shaft rod 35 is guided by the second section 152, the buckle arm 32 swings upward in an arc in the same direction (clockwise direction) (refer to Figure 9 shown), and the buckle body 321 follows the movement and lifting of the buckle arm 32. In this way, the entire latch handle 3 can swing like a cradle relative to the housing 1 in the same direction (clockwise direction). At the same time, after the latch handle 3 swings, the elastic member 36 can be deflected under the block of the blocking portion 113 and store elastic energy. In other words, the electrical connection plug 100 can have a better additional fixing effect (not easy to separate) through the latch handle 3 and the guiding groove 15, and of course can also have a better anti-pulling effect.

[0037] When the user releases the pressing on the pressing portion 311, due to the elastic restoring force of the elastic member 36, the entire latch handle 3 is pulled in the opposite direction (counterclockwise direction) and returns to the original position (as Figure 6 shown).

[0038] As Figures 7 to 9 and Figure 5 shown, during the insertion process of the aforementioned terminal block device, when the electrical connection plug 100 is inserted into the electrical connection socket 500, the buckle body 321 of the latch handle 3 will be correspondingly buckled in the buckle portion 51 of the electrical connection socket 500 (as shown in Figure 8) to provide a better additional fixation for the terminal block device, so that the terminal block device has a better anti-pullout effect.

[0039] Thus, when the electrical connection plug 100 is to be removed from the electrical connection socket 500, Figure 9 As shown, the pressing portion 311 of the locking handle 3 is first pressed, and then as mentioned above, the entire locking handle 3 will swing in the same direction (clockwise) relative to the shell 1 like a cradle, so that the buckle body 321 follows the buckle arm 32 to swing upward in an arc and lift up, and then the lifted buckle body 321 can be separated from the buckle portion 51 (at the same time, due to the swing of the locking handle 3, the elastic component 36 can be forced to swing and elastically store force), so that the locking handle 3 no longer locks the electrical connection socket 500, and the electrical connection plug 100 can be reversely unplugged from the electrical connection socket 500.

[0040] In particular, when locking, since the lock handle 3 swings like a cradle in the aforementioned direction (clockwise direction), so that the buckle body 321 buckles the buckle portion 51 after swinging, it has the effect of forcing the electrical connection socket 500 to be close to the electrical connection plug 100, so as to ensure that the electrical connection plug 100 and the electrical connection socket 500 will not be loose. Moreover, when unlocking, since the lock handle 3 also swings like a cradle (swings in the opposite direction (counterclockwise direction)), it can drive the buckle body 321 to move away from the buckle portion 51 and lift upward, that is, it can release the buckle body 321 from the buckle portion 51, and can also lift the buckle body 321 away from the buckle portion 51, so as to ensure that the electrical connection plug 100 can be smoothly removed from the electrical connection socket 500.

[0041] In addition, if Figure 7 As shown, a second threaded member (e.g., a nut) S2 may be pre-set in the electrical connection socket 500, so that after the electrical connection plug 100 and the electrical connection socket 500 are plugged into each other, a first threaded member (e.g., a screw) S1 is inserted into the electrical connection plug 100 and the electrical connection socket 500 and threadedly connected to the second threaded member S2, so that the electrical connection plug 100 and the electrical connection socket 500 can be further fixed together by threading.

[0042] In summary, the terminal block device and the locking electrical connection plug thereof of the present invention can achieve the expected purpose and effect and solve the deficiencies of the prior art.

[0043] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
