Description

Technical Field

[0001] The utility model relates to a wiring terminal assembly. Background Art

[0002] A wiring terminal is a common device for realizing electrical connection between different wires. The wiring terminal generally includes a housing, and two wiring modules located at both ends or the same end of the housing. The wiring module includes a jack for inserting a wire end and a clip located in the jack and capable of clamping and fixing the wire. A handle capable of controlling the clip to clamp / loosen the conductor is movably arranged on the outer side of the housing, and a conductive part capable of electrically connecting the wires connected in different wiring modules is arranged on the inner side of the housing.

[0003] In order to realize the parallel connection between different conductive circuits, the housings of the existing wiring terminals on the market can be connected side by side through buckles, and a connection hole is arranged on the outer side of the housing, and the conductive connection between the conductive parts of different wiring terminals can be realized by inserting a conductive row. For example, a structure for realizing the parallel connection between a plurality of wiring terminals connected side by side through a conductive part is disclosed in a Chinese utility model - a parallelizable wire connector (CN210806040U) applied for and authorized by the applicant recently.

[0004] It can be seen that the multiple wiring terminals of the existing wiring terminal assembly are arranged horizontally in the horizontal direction. Affected by the space size of the use environment, this arrangement method has certain limitations on the number of wiring terminals. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a wiring terminal assembly capable of reducing the occupation of horizontal space.

[0006] To achieve the above object, the utility model provides a terminal block assembly, which includes two sets of terminal blocks. Each set of terminal blocks includes a plurality of terminal blocks connected side by side horizontally. The terminal block includes connection parts at both ends. The terminal block can electrically connect the wires connected to the connection parts at both ends thereof. The connection part includes handles arranged at the upper parts of both ends of the terminal block. By cooperating the handles with the metal clips of the connection part, clamping and releasing operations on the conductors connected to the connection part can be realized. The two sets of terminal blocks are arranged at intervals longitudinally. The two sets of terminal blocks are respectively the first set of terminal blocks located above and the second set of terminal blocks located below. The two sets of terminal blocks are arranged longitudinally, reasonably utilizing the longitudinal space and reducing the occupation of the horizontal space. There are several brackets detachably connected between the middle part of the lower end of the first set of terminal blocks and the middle part of the upper end of the second set of terminal blocks. Through the brackets, the relative positions of the first set of terminal blocks and the second set of terminal blocks are fixed, and at the same time, an operation space for the handles of the second set of terminal blocks to rotate is reserved between the first set of terminal blocks and the second set of terminal blocks, which will not affect the wiring operation between the second set of terminal blocks and the wires.

[0007] Furthermore, at least the middle parts of the lower ends of the terminal blocks of the first set of terminal blocks are provided with first clamping components, and the upper ends of the brackets are provided with second clamping components. Each first clamping component of each terminal block can be used to establish a clamping and positioning cooperation with the second clamping component of one of the brackets, and the corresponding number of brackets can be selected for assembly as needed to improve the stability when the two sets of terminal blocks are connected. For example, when the number of terminal blocks of the two sets of terminal blocks is large, in order to avoid shaking, a plurality of brackets can be evenly spaced between the two sets of terminal blocks.

[0008] Furthermore, at least the middle parts of the upper ends of the terminal blocks of the second set of terminal blocks are provided with grooves, and conductive connection holes are provided at the bottoms of the grooves. The grooves of the plurality of terminal blocks of the second set of terminal blocks are joined together. The lower ends of the brackets are provided with third clamping components, and the two inner walls of the grooves are provided with fourth clamping components that cooperate with the third clamping components for clamping. This structural design enables the brackets and the second set of terminal blocks not to block the grooves when connected, retaining the parallel connection function. When parallel connection is required, a conductive bar can be inserted into the grooves, and the terminal blocks of the second set of terminal blocks can be electrically connected together through the conductive connection holes.

[0009] Furthermore, the fourth clamping component is a clamping groove symmetrically arranged on the two inner walls of the groove, and the third clamping component is a clamping foot arranged on both sides of the lower end of the bracket. The clamping foot and the clamping groove form a sliding fit, enabling the clamping foot to move along the splicing direction of the second set of terminal blocks. The clamping foot can be slid into the groove along the end position of the second set of terminal blocks in the splicing direction, facilitating the disassembly and assembly cooperation with the bracket.

[0010] Furthermore, a recess is formed between the two clamping feet of the bracket, which can play a role of making way and reduce the size requirements for the conductive bar.

[0011] Furthermore, the bracket is provided with notches on both sides corresponding to the splicing direction of each group of connection terminals, which can reduce the weight of the bracket, reduce the material used, and reduce the production cost of the bracket.

[0012] The beneficial effects of the present invention are as follows: the terminal block assembly of the present invention has a simple and compact structure, is easy to use, and can reduce the occupation of the horizontal space of the installation environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The embodiment of the terminal block assembly of the present invention is as follows: Figure 1-6As shown in the figure: It includes two sets of terminal blocks (11, 12). Each set of terminal blocks includes a plurality of terminal blocks 10 connected side by side horizontally. The terminal block 10 includes terminal portions at both ends. The terminal block 10 can electrically connect the wires connected to the terminal portions at its two ends. The terminal portion includes a handle 101 arranged at the upper part of both ends of the terminal block 10 and a jack 102 arranged at the lower part. By the cooperation of the handle 101 and the metal clip of the terminal portion arranged in the jack 102, clamping and loosening operations on the conductor connected to the terminal portion are realized. Inside the terminal block 10, there is also provided a conductive member that can electrically connect the wires connected to the terminal portions at its two ends. The basic structure and principle of the terminal block 10 are relatively conventional and will not be elaborated in this text. The two sets of terminal blocks are arranged at intervals longitudinally. The two sets of terminal blocks are the first set of terminal blocks 11 located above and the second set of terminal blocks 12 located below. The two sets of terminal blocks (11, 12) are arranged longitudinally, reasonably utilizing the longitudinal space and reducing the occupation of the lateral space. Between the middle part of the lower end of the first set of terminal blocks 11 and the middle part of the upper end of the second set of terminal blocks 12, several brackets 2 are detachably connected. Through the bracket 2, the relative positions of the first set of terminal blocks 11 and the second set of terminal blocks 12 are fixed, and at the same time, an operation space (such as Figure 5 the space located on both sides of the bracket 2 shown in the figure) is reserved between the first set of terminal blocks 11 and the second set of terminal blocks 12 for the handle 101 of the second set of terminal blocks 12 to rotate, which will not affect the wiring operation between the second set of terminal blocks 12 and the wires.

[0020] Such as Figure 3 、 6 As shown in the figure, at the middle part of the lower end of each terminal block 10 of the first set of terminal blocks 11, a first clamping component 31 is provided. At the upper end of the bracket 2, a second clamping component 32 is provided. In this embodiment, the first clamping component 31 is a slot, and the second clamping component 32 is a buckle. Each first clamping component 31 owned by each terminal block 10 can be used to establish a clamping positioning fit with a second clamping component 32 of one of the brackets 2. The corresponding number of brackets 2 can be selected for assembly according to needs, improving the stability when the two sets of terminal blocks are connected. For example, when the number of terminal blocks 10 of the two sets of terminal blocks is large, in order to avoid shaking, a plurality of brackets can be evenly arranged at intervals between the two sets of terminal blocks 10. In this embodiment, as Figure 2 shown in the figure, 2 brackets 2 arranged at intervals are adopted. In other embodiments, it can also be that the first clamping component 31 is a buckle and the second clamping component 32 is a slot.

[0021] Such as Figure 4 、 5As shown in Figure 6, a groove 103 is provided in the middle of the upper end of each terminal block 10 of the second group of terminal blocks 12, and a conductive connection hole 104 is provided at the bottom of the groove 103. The grooves 103 of multiple terminal blocks of the second group of terminal blocks 12 are spliced together to form a long groove. The lower end of the bracket 2 is provided with a third clamping component 33, and the inner walls on both sides of the groove 103 are provided with a fourth clamping component 34 that cooperates with the third clamping component 33. This structural design ensures that the bracket 2 and the second group of terminal blocks 12 will not block the groove 103 when connected, retaining the parallel function. When parallel connection is required, the conductive bar can be inserted into the groove 103, and the conductive connection holes 104 can be used to electrically connect the terminal blocks 10 of the second group of terminal blocks.

[0022] In this embodiment, the fourth engaging member 34 is a slot symmetrically disposed on the inner walls of the groove 103 on either side. The third engaging member 33 is a foot disposed on either side of the lower end of the bracket 2. The foot and the slot form a sliding fit, enabling the foot to move along the splicing direction of the second set of connecting terminals. The foot can be slidably inserted into the groove 103 from the end of the second set of connecting terminals 12 along the splicing direction, facilitating assembly and disassembly with the bracket 2.

[0023] like Figure 5 、 6 As shown, a recess 20 is formed between the two legs of the bracket 2, which can provide clearance and reduce the size requirements of the conductive bar. In addition, the bracket 2 is provided with notches 21 on both sides corresponding to the splicing direction of each group of terminal blocks, which can reduce the weight of the bracket 2, reduce the material used, and reduce the production cost of the bracket 2.

[0024] In other embodiments, three or more groups of connection terminals may be used, and these groups of connection terminals may be connected sequentially along the longitudinal direction according to the above-mentioned structure.

[0025] The above embodiment is only one preferred embodiment of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included in the protection scope of the present invention.
