[0001] The utility model relates to the technical field of electrical equipment, in particular to a wiring terminal and a wiring structure. Background Art

[0002] The through-wall terminals in the terminal blocks are used as electrical equipment connectors and are mainly used for the installation of outdoor electrical equipment, such as monitoring and alarm equipment, as well as wind inverters or photovoltaic inverters.

[0003] At present, commonly used through-wall terminals include a single-row structure and a double-row staggered structure. In the single-row structure, the various wiring terminals are arranged in the same row, which occupies a large space and has high material costs. In the double-layer staggered structure, the live wire terminals are arranged on the same layer, and the neutral wire and ground wire terminals are arranged on the same layer. Compared with the single-row structure, the cost is lower and the space occupied is smaller. However, since outdoor electrical equipment usually needs to lead the wires from indoors to outdoors and the wire connections are required to have high waterproof performance, these two types of through-wall terminals have poor waterproof performance and are difficult to meet the actual needs of users. Utility Model Content

[0004] In view of this, the utility model provides a wiring terminal and a wiring structure to overcome the problems of poor waterproof performance and large occupied space of the through-wall terminal in the wiring terminal in the prior art.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0040] like Figure 1-Figure 11 This embodiment provides a wiring terminal, preferably a through-wall terminal, or other types of terminal structures, including: a housing 1, a wiring body 2, and a sealing member 3. Figure 1 As shown, the through-wall terminals in the prior art are in a single-row structure 5 and a double-row staggered structure 6 .

[0041] Among them, there is no restriction on the specific shape of the shell 1, as long as it can accommodate a built-in partial wiring body 2 and set an installation opening 102 and a first wire-passing opening 103. The material is an insulating material, specifically plastic, etc. The shell 1 has a built-in accommodating cavity 101, which is respectively connected to the installation opening 102 and the first wire-passing opening 103. The installation opening 102 and the first wire-passing opening 103 avoid each other, wherein the installation opening 102 can allow an external cable 404 to pass through and extend into the accommodating cavity 101, and the first wire-passing opening 103 allows a part of the wiring body 2 to pass through and extend out of the accommodating cavity 101. Preferably, the housing 1 is arranged in a square shell shape, which is convenient for connection and installation with an external structure. The opening position and opening size of the installation opening 102 and the first wire-passing opening 103 can be arranged according to the size and shape of the external cable 404 and the part of the wiring body 2 extending out of the accommodating cavity 101 and the required installation space.

When the bucket-shaped housing 1 is placed horizontally, its top surface and one of the side surfaces are opened to form the installation opening 102, and the first wire-passing opening 103 is arranged on the other side surface. Figure 2 As shown, when the bucket-shaped housing 1 is placed vertically, its end surface facing the paper is the top surface when it is placed horizontally, and together with its downward end surface, it is opened to form an installation opening 102, and the first wire opening 103 is arranged on the left end surface.

[0042] One end of the wiring body 2 is arranged in the accommodating cavity 101, suitable for connecting to the external cable 404, and the other end passes through the first wire opening 103, suitable for connecting to other external structures. In this embodiment, the external structure is outdoor electrical equipment, which can be specifically a monitoring, alarm equipment, wind inverter or photovoltaic inverter, etc.

[0043] The seal 3 is arranged on the outer wall of the shell 1, and is correspondingly arranged around the first wire opening 103, and is suitable for abutting the external structure. In this embodiment, the seal 3 is specifically a sealing ring, and the material may be silicone, rubber, etc. Preferably, an annular groove for accommodating the limit seal 3 is also correspondingly arranged on the outer wall of the shell 1.

[0044] The housing 1 is provided with an installation opening 102 and a first wire-passing opening 103 which are spaced apart from each other. The external cable 404 extends into the installation opening 102 to be connected with the wiring body 2, and the end of the wiring body 2 extends out of the first wire-passing opening 103 to be connected with the external structure. With such an arrangement, on the one hand, the cable 404 is stably connected with the wiring body 2 through the protection of the housing 1, and the installation opening 102, as a side structure through which the cable 404 passes, can be built-in or filled in the installation environment of the terminal block to prevent external dust and water from entering the housing 1. On the other hand, when connected with the external structure, the sealing member 3 which is circumferentially arranged and abuts against the first wire-passing opening 103 on the outer wall of the housing 1 and which is against the external structure, the first wire-passing opening 103 is effectively sealed, and the wiring body 2 extending out of the first wire-passing opening 103 can achieve a sealed connection with the external structure, preventing external dust and water from entering the housing 1 from this side. In summary, such an arrangement effectively overcomes the defect of poor waterproof performance of the through-wall terminal in the wiring terminal in the prior art.

[0045] Specifically, the housing 1 comprises: a load-bearing bottom wall 104, a connecting side wall 105 and a connecting enclosure 106. Preferably, the load-bearing bottom wall 104, the connecting side wall 105 and the connecting enclosure 106 are integrally formed.
