Fig. 1 is a schematic view for explaining a construction of an exemplary embodiment of a terminal block of the present utility model. Fig. 2 shows a schematic view of the structure of an exemplary embodiment of the terminal block of the present utility model from two angles.

Referring to fig. 1 and 2, the terminal block includes a body 10. The body 10 comprises a bottom plate 11 and four side plates 12 which are arranged around the edge of the bottom plate 11. The four side panels 12 and the bottom panel 11 together form a receiving space for the wiring modules of power supply, telephone, television. The side plate 12 may have a hole formed therein for wiring the wiring module in the accommodation space to the outside.

The terminal block further includes a pair of first clamping portions 21 and a pair of second clamping portions 22. The first clamping portion 21 and the second clamping portion 22 are respectively disposed on the outer side surfaces of the two opposite side plates 12. The pair of first clamping parts 21 of the terminal bottom box can extend into between the pair of second clamping parts 22 of the other terminal bottom box and are clamped with the pair of second clamping parts 22. The wiring bottom box is simple in structure, the requirement on assembly force is reduced through the structural design of two clamping joints, the operation is convenient, and the wiring bottom box is not easy to deform after multi-connection installation.

The first clamping portion 21 and the second clamping portion 22 of the terminal bottom box can adopt various design modes.

For example, as shown in fig. 1 and 2, the first clamping portion 21 may be designed as a snap-fit and the second clamping portion 22 as a snap-fit groove. Specifically, a protruding portion 31 is disposed on each first clamping portion 21 (buckle), and the protruding portion 31 on one first clamping portion 21 (buckle) of each pair of first clamping portions 21 (buckle) is disposed opposite to the protruding portion 31 on the other first clamping portion 21 (buckle) of the pair of first clamping portions 21 (buckle). The second clamping portion 22 (clamping groove) is provided with a notch 32, and the notch 32 can be matched with the protruding portion 31 of the first clamping portion 21 (clamping buckle) of the other terminal bottom box.

Other designs of the first and

second clamping portions

21, 22 than those shown in fig. 1 and 2 are possible. For example, the second engaging portion 22 may be designed as a buckle, and the first engaging portion 21 may be designed as a slot. Specifically, a protruding portion is disposed on each second clamping portion 22 (buckle), and a protruding portion on one second clamping portion 22 (buckle) of each pair of second clamping portions 22 (buckle) is disposed opposite to a protruding portion on the other second clamping portion 22 (buckle) of the pair of second clamping portions 22 (buckle). The first clamping portion 21 (clamping groove) is provided with a notch which can be matched with a protruding portion of the second clamping portion 22 (clamping buckle) of the other terminal bottom box. In addition to the above two ways, the first clamping portion 21 and the second clamping portion 22 may further adopt other structural designs, which are not limited herein.

The pair of second clamping parts 22 of the terminal block can be arranged on the main body 10 of the terminal block in various layout modes. For example, each pair of second clamping portions 22 may be arranged in the length direction or the width direction of the terminal block on the body 10, or may be arranged in the depth direction of the terminal block. Since the first clamping portion 21 is clamped with the second clamping portion 22, the arrangement of the first clamping portion 21 is identical to that of the second clamping portion 22. Preferably, each pair of second clamping parts 22 are arranged along the depth direction of the terminal bottom box, in this way, the terminal bottom box and other terminal bottom boxes are clamped at two positions with different depths of the terminal bottom box body, so that the problems of buckling deformation and the like caused by connection of the terminal bottom box body only at the top end or the bottom end are avoided. Further, when the arrangement is performed in a deep manner, one of the second clamping portions 22 and the bottom plate 11 may be arranged flush with the bottom plate 11 of the terminal bottom box, so that the terminal bottom box is easy to be demolded and convenient to manufacture.

In order to strengthen the strength of the engaging portions, the first engaging portion 21, the second engaging portion 22, or both the first engaging portion 21 and the second engaging portion 22 may be provided with the reinforcing rib 40. The reinforcing rib 40 connects the side plate 12 and the engaging portion. The reinforcing ribs 40 may be provided at different positions of the engaging portion, for example, may be provided at both side positions of the engaging portion, or may be provided at upper and lower positions of the engaging portion.

In order to increase the reliability of connection between the terminal bottom boxes and further reduce the possibility of deformation and tilting of the terminal bottom boxes, a pair of third clamping parts 23 and a pair of fourth clamping parts 24 may be further disposed on the body of the terminal bottom box, and the third clamping parts 23 may form a clamping connection with the fourth clamping parts 24 of another terminal bottom box. The third engaging portion 23 and the first engaging portion 21 are provided on the same side plate 12, and the fourth engaging portion 24 and the second engaging portion 22 are provided on the same side plate 12. Specifically, the third clamping portion 23 and the first clamping portion 21 may be designed to have the same structure, and the fourth clamping portion 24 and the second clamping portion 22 may be designed to have the same structure; alternatively, the third engaging portion 23 and the second engaging portion 22 may be designed in the same type of structure, and the fourth engaging portion 24 and the first engaging portion 21 may be designed in the same type of structure. The same structure can be the same size or different sizes.

When assembling, two or more terminal blocks can be installed together, then the terminal blocks are installed in the wall, and then the power supply, telephone or television terminal module is installed in the terminal blocks.

As shown in fig. 3, the two terminal blocks have been assembled together. At this time, the pair of first clamping portions 21 of one terminal bottom box extend between the pair of second clamping portions 22 of the other terminal bottom box, and the protruding portions 31 of the buckle are buckled in the corresponding notches 32. When the two terminal blocks are pulled to both sides with opposite-direction forces, respectively, the two terminal blocks cannot be separated because the boss 31 is located in the notch 32. The second clamping portion 22 of the terminal bottom box after being assembled together can be designed to be in a loose state, and can also be designed to elastically deform and clamp the first clamping portion 21. The design is in a loose state, so that the terminal bottom box can be further ensured not to deform; the design is elastic deformation, so that the connection reliability between the two terminal bottom boxes can be further enhanced.
