Detailed ways

In order to further understand the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are only provided for reference and illustration and are not intended to limit the present invention.

Please refer to FIG1 , which is a three-dimensional exploded view of the present invention. The present invention provides a composite spring-type wiring device, comprising a housing 1, an operating assembly 2 and a conducting terminal 3; wherein:

The housing 1 may be composed of two halves 10, 11, and a hollow portion 100, 110 and a wire insertion hole 101, 111 connected to the outside of the housing 1 by the hollow portion 100, 110 are formed in the housing 1. The hollow portion 100, 110 can be used for arranging the operating assembly 2 and the conductive terminal 3 (as shown in FIG. 4), and the wire insertion hole 101, 111 is used for inserting a wire 4 (as shown in FIG. 6 or FIG. 7).

Please refer to FIG. 2 and FIG. 3 , the operating assembly 2 includes an operating member 20, a first elastic sheet 21 and at least one second elastic sheet 22. The operating member 20 has a lever 200, a first abutting portion 201 and a second abutting portion 202 disposed at one end of the lever 200, and a pulling portion 203 disposed at the other end of the lever 200. The first abutting portion 201 has a pivot 201a, which can be pivotally connected through pivots 102 and 112 disposed on the inner walls of the hollow portions 100 and 110 of the housing 1, so that the operating member 20 can swing according to the pivot 201a. The first abutting portion 201 has a first abutting surface 201b, and the second abutting portion 202 is disposed on the first abutting portion 201 and has at least one second abutting surface 202a protruding from the first abutting surface 201b. The first abutting portion 201 and the second abutting portion 202 can both be composed of cam structures to respectively form the first abutting surface 201b and the second abutting surface 202a through their respective cam surfaces.

As mentioned above, the first elastic sheet 21 and the second elastic sheet 22 are stacked on each other. The first elastic sheet 21 has a first elastic section 210, a first fixed end 211 formed at one end of the first elastic section 210, and a first pressing end 212 formed at the other end of the first elastic section 210; and the second elastic sheet 22 also has a second elastic section 220, a second fixed end 221 formed at one end of the second elastic section 220, and a second pressing end 222 formed at the other end of the second elastic section 220. After the first and second elastic sheets 21 and 22 are stacked, the first elastic section 210 of the first elastic sheet 21 corresponds to the first abutting surface 201b at a side adjacent to the first pressing end 212, and the second elastic section 220 of the second elastic sheet 22 corresponds to the second abutting surface 202a at a side adjacent to the second pressing end 222. In the embodiment of the present invention, in order to facilitate the integration between the operating member 20 and the first and second spring plates 21 and 22, a first groove 210a may be provided on the first elastic section 210, and a second groove 220a may be provided on the second elastic section 220. The width of the first groove 210a and the second groove 220a is just wide enough for the lever 200 to be partially inserted, so as to prevent the above-mentioned components from interfering with or conflicting with each other when space is limited.

In addition, as shown in FIG. 5 , in order to facilitate the deformation of the first and second elastic sheets 21 and 22 under force, the first elastic section 210 and the second elastic section 220 are both curved and can correspond to the protruding columns 103 and 113 (as shown in FIG. 1 ) disposed on the inner walls of the hollow portions 100 and 110 of the housing 1 , so as to be able to surround the protruding columns 103 and 113 through the curved portions.

Referring to FIG. 1 and FIG. 4 , the conductive terminal 3 has a terminal body 30 in an upright position, and a wire carrying portion 31 formed by bending the terminal body 30; the terminal body 30 can be placed against one side of the hollow portion 100 of the housing 1, and the wire carrying portion 31 corresponds to one side of the wire insertion holes 101, 111 of the housing 1. The terminal body 30 is provided with a positioning portion 300 for positioning the first fixed end 211 and the second fixed end 221 of the first and second spring sheets 21, 22, and a wire blocking portion 301 is provided on one side of the terminal body 30 away from the wire insertion holes 101, 111. The wire carrying portion 31 can be provided with one or more protruding structures 310 to increase the contact with the wire 4, and one or more pins 311 protruding from the wire carrying portion 31 are bent downward to protrude from the housing 1. In addition, as shown in FIG. 5 , when the first and second spring sheets 21 and 22 are in a non-stressed state, the first pressing end 212 and the second pressing end 222 of the first and second spring sheets 21 and 22 are both swung toward the wire carrying portion 31 and blocked in the wire insertion holes 101 and 111 in sequence.

Therefore, by means of the above-mentioned structure, the composite spring-type wiring device of the present invention can be obtained.

5 and 6 , when the wire 4 is to be inserted into the wire insertion holes 101 and 111, the pulling portion 203 of the operating member 20 can be manually pulled, and the pulling portion 203 extends to the outside of the housing 1 through the lever 200, so that when the pulling portion 203 is manually pulled, the first abutting top portion 201 and the second abutting top portion 202 can be flipped through the lever 200, and the first abutting top surface 201b of the first abutting top portion 201 pushes against the first elastic section 210 of the first elastic sheet 21, and the second abutting top surface 202a of the second abutting top portion 202 pushes against the second elastic section 220 of the second elastic sheet 22 (as shown in FIG. 6 ). In this way, the first pressing end 212 and the second pressing end 222 can move toward the side away from the wire insertion holes 101 and 111, and make room for the space inside the wire insertion holes 101 and 111, so that the wire 4 can be smoothly inserted until it is inserted into the wire carrying portion 31 of the conductive terminal 3, as shown in FIG. 7 .

Next, as shown in FIG. 7 , after the pull portion 203 is manually pulled back to the original position, it can be further fixed in the housing 1 by the first abutting portion 201. Specifically, a recessed slot 201c is provided below the first abutting portion 201, and a block 104, 114 corresponding to the slot 201c is provided in the housing 1. The block 104, 114 can be formed by the inner walls of the two halves 10, 11 of the housing 1 extending toward each other and merging, or a structure such as a rib is formed inside the housing 1 as a support for the block 104, 114, so as to provide sufficient structural strength to allow the slot 201c to be locked on the block 104, 114. In this way, it can also be ensured that the first pressing end 212 of the first spring sheet 21 and the second pressing end 222 of the second spring sheet 22 are pressed against the wire 4 by their elastic force.

Furthermore, in order to facilitate manual operation of the pull portion 203 of the operating member 20, a first pull surface 203a and a second pull surface 203b opposite to the first pull surface 203a may be formed on the pull portion 203; the first pull surface 203a is used to pull the pull portion 203 upward when inserting the wire 4 (as shown in FIG. 6), and the second pull surface 203b is used to pull the pull portion 203 back to its original position when the wire 4 is inserted to a fixed position (as shown in FIG. 7). In addition, an operating hole 203c for inserting a tool (not shown) may be provided on the first pull surface 203a, so that the operation can also be performed by a tool.

It is worth mentioning that the second spring pieces 22 of the present invention can be further increased to several numbers and overlapped with the first spring piece 21 and the existing second spring piece 22 . Meanwhile, the second abutting surface 202 a is further increased according to the number of the second spring pieces 22 , so as to further increase the clamping points for the wire 4 .

Therefore, by using the composite spring-type wiring device of the present invention, the wire 4 can be pressed by a plurality of springs (such as the first spring 21 and the second spring 22) to increase the clamping points of the wire 4, thereby improving the stability of the plug-in connection and further preventing the wire 4 from loosening or even coming loose. In addition, the operating component 2 can be designed as a cam structure by the first abutting top 201 and the second abutting top 202, so that the operating member 20 can be operated by the lever principle, making the wire 4 more convenient and faster in the wiring and disconnection operations, achieving the purpose of tool-free operation, thereby improving the work efficiency of the operator, and helping to reduce the cost of personnel and other expected effects.
