DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 A combined splicing terminal block may include a plurality of terminal modules 30, a first side plate 10, and a second side plate 20. Every two adjacent terminal modules 30 in the plurality of terminal modules 30 are connected to each other, so that the plurality of terminal modules 30 are connected in a row to form a terminal row. The first side plate 10 and the second side plate 20 are respectively fastened and fixed on the opposite sides of the terminal row and are fixedly connected thereto, and the first side plate 10 and the second side plate 20 can cover the positioning parts 32 and the connecting parts 33 at both ends of the terminal row, so that the terminal row is relatively flat as a whole and convenient to use.

[0025] See also Figures 2 to 4 The terminal module 30 includes a conducting portion 31, a positioning portion 32 and a connecting portion 33. The connecting portion 33 and the positioning portion 32 are respectively formed on opposite sides of the conducting portion 31, and every two adjacent terminal modules 30 can be assembled by clamping the adjacent connecting portions 33 and positioning portions 32. The conducting portion 31 can be used to fix the wires or cables to be connected.

[0026] In this embodiment, the conducting part 31 includes an end shell 311, a conductive sleeve 312, two locking bolts 313 and a slot 314. The end shell 311 can be made of an insulating material, and a cavity can be formed in the middle thereof. The conductive sleeve 312 can be made of a conductive metal material, and the conductive sleeve 312 is inserted and fixed in the cavity of the end shell 311, and the wires to be connected can be inserted from both ends thereof. Both locking bolts 313 are threadedly connected to the top or bottom of the end shell 311, and the locking bolts 313 extend into the conductive sleeve 312 toward one end of the end shell 311. After tightening the locking bolts 313, the conductive inner core of the corresponding wire can be pressed and fixed in the conductive sleeve 312 for conductive connection. The slot 314 is formed on the side of the end shell 311 facing the connecting part 33, and is used to cooperate with the spring 334 placed in the connecting part 33.

[0027] In this embodiment, the top and bottom of the side of the positioning portion 32 facing away from the end shell 311 are symmetrically formed with limiting protrusions 321, and the gap between the two limiting protrusions 321 and the positioning portion 32 forms a guide groove 322 that matches the connecting portion 33. The top and bottom of the connecting portion 33 are formed with snap-fit ​​grooves 331, and the two snap-fit ​​grooves 331 are respectively matched by the two limiting protrusions 321, and the side of the connecting portion 33 facing away from the end shell 311 is matched with the guide groove 322. When two adjacent terminal modules 30 are connected, the connecting portion 33 in one terminal module 30 can be inserted toward the positioning portion 32 in the other terminal module 30, and the two locking grooves 331 are respectively passed by the two limiting protrusions 321, and the side of the connecting portion 33 facing away from the end shell 311 is inserted into the guide groove 322, thereby limiting the left and right directions of the two terminal modules 30.

[0028] In this embodiment, the connecting portion 33 further includes a protruding groove 332, a positioning bead 333 and a spring 334. One end of the spring 334 is inserted into the slot 314, and the other end of the spring 334 is connected to the positioning bead 333. The positioning bead 333 can be movably arranged in the protruding groove 332 by utilizing the deformation of the spring 334. The opening of the protruding groove 332 on one side facing the end shell 311 is slightly larger than the opening on the other side, so that the part of the positioning bead 333 close to one side of the connecting portion 33 can protrude out of the protruding groove 332. A limiting groove 323 is formed on the positioning portion 32, which penetrates the positioning portion 32, and the part of the positioning bead 333 protruding out of the protruding groove 332 cooperates with the limiting groove 323. When the connecting part 33 is inserted into the positioning part 32, the positioning bead 333 first contacts the outer wall of the positioning part 32, and the positioning bead 333 is pushed into the protruding groove 332; when the positioning bead 333 moves toward the limiting groove 323, under the elastic deformation action of the spring 334, the positioning bead 333 can pass through the protruding groove 332 and extend into the limiting groove 323, thereby limiting the front and rear directions of the two terminal modules 30.

[0029] In this embodiment, the second connecting groove 335 and the first connecting groove 324 are formed on the opposite sides of the connecting portion 33 and the positioning portion 32, and the second connecting groove 335 and the first connecting groove 324 are located in the same horizontal plane. The second connecting groove 335 and the first connecting groove 324 pass through the protruding groove 332 and the limiting groove 323 respectively, so that after the two terminal modules 30 are connected, the adjacent second connecting grooves 335 and the first connecting grooves 324 of the two are connected to form a channel through which the positioning beads 333 can be pushed by the user, so that the user can use a slender rod-shaped tool in the channel to push the positioning beads 333 to compress the spring 334, and then the two terminal modules 30 can be separated and disassembled.

[0030] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
