Description

Technical Field

[0001] The utility model relates to the technical field of distribution equipment, specifically, to a double-row parallel terminal block. Background Art

[0002] A terminal block is an insulating component that bears multiple or multiple groups of mutually insulated terminal components and is used to fix the support member. The function of the terminal block is to connect the lines of the in-panel equipment and the out-panel equipment, playing the role of signal (current and voltage) transmission. With the terminal block, the wiring is made beautiful, the maintenance is convenient, and when connecting between long-distance lines, it is mainly reliable, and the construction and maintenance are convenient.

[0003] There are usually multiple interfaces on the terminal block, and each interface is independent. When the user wants to parallel two interfaces, it is necessary to additionally set wires to connect the lines of the two required interfaces, which is quite troublesome. Summary of the Utility Model

[0004] In summary, to overcome the deficiencies of the prior art, the utility model provides a double-row parallel terminal block that can be directly paralleled.

[0005] To achieve the above object, the utility model provides the following technical solution: A double-row parallel terminal block, including a terminal block main body, a screw group, and terminal pieces. The terminal block main body is provided with an upper working position and a lower working position. Both the upper working position and the lower working position are provided with connection positions. It further includes a parallel connection piece. The parallel connection piece includes connection pieces at both ends and a bending piece in the middle. The connection pieces at both ends are respectively located in the connection positions of the upper working position and the lower working position. Each connection position is provided with a screw group. One of the connection positions is provided with the terminal piece. The screw group passes through the connection piece and is connected to the terminal block main body.

[0006] With such a setting, during use, the connection heads that need to be wired can be inserted into the connection positions of the upper working position or the lower working position, and then the corresponding screw group is used to pass through the connection head to fix it in the connection position. The connected connection heads will be connected to the connection pieces of the parallel connection piece by relying on the screw group. After the connection heads are placed in the upper and lower working positions and connected, the connection heads on each connection position will be connected to each other in a parallel state, and then a unified output is made by one terminal piece. The installed multiple connection heads directly enter the parallel state without the need for additional wires to operate the connection.

[0007] Further, there are several connection positions in both the upper working position and the lower working position.

[0008] With such a setting, multiple connection positions can parallel the required number of connection heads according to the user's needs, and leaving the remaining positions empty does not affect the use.

[0009] Furthermore, a partition is provided between two adjacent connection positions in the same workstation, and a first slot adapted to the parallel piece is provided at a position corresponding to the partition.

[0010] With such arrangement, the partition can separate each connection position, so that the bottom plate of the screw group in each connection position is adapted to the connection position and will not be rotated together with the screw. At the same time, the first slot on the parallel plate is more stable after being inserted into the partition.

[0011] Furthermore, a positioning groove with a height not less than the thickness of the connecting piece is provided at the bottom of the partition.

[0012] With such arrangement, the first slot will be inserted from the position of the positioning slot and interlocked with the positioning slot, so that the connection is tighter, and its vertical movement is also limited, making it more stable.

[0013] Furthermore, the outer side of the top surface of the positioning groove is chamfered.

[0014] With such arrangement, the outer side of the positioning groove will present a flared shape, making it easier to insert the parallel piece.

[0015] Furthermore, an insert is respectively provided on both sides of one end of the connecting piece located at the lower station facing the upper station, and a second slot is provided at the position of the lower station corresponding to the insert, and the insert is interference fit with the second slot.

[0016] With this arrangement, the inserts on both sides of the connecting piece will be inserted into the second slots of the lower station. Since the two are interference fit, the connection will be more secure after insertion and will not easily loosen.

[0017] Furthermore, the insert is in a shape with an arch in the middle.

[0018] With such arrangement, the overall height of the arched middle portion of the insert is greater than the second slot, and after insertion, the insert will deform to press against the second slot, making it easier to insert.

[0019] Furthermore, empty grooves are provided on both sides of the bending piece at positions corresponding to the inserting piece.

[0020] With such arrangement, the insert can be directly cut and bent from the bending sheet, and an empty slot will be left at the position after the material is taken, which is easier to process and saves costs.

[0021] Furthermore, the terminal block body is provided with a parallel area and an independent area, and the parallel piece is located in the parallel area.

[0022] With this arrangement, the terminal block will have the functions of both independent wiring and parallel wiring, and wiring can be performed at the corresponding position according to the user's needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] With such a setting, the inserts 4011 on both sides of the connecting piece 401 will be inserted into the second slots 1021 of the lower working station 102. Since they are in interference fit, the connection will be more firm and not easy to loosen after insertion.

[0040] Preferably in this embodiment, the insert 4011 is in a shape with a middle arch.

[0041] With such a setting, the overall height after the middle of the insert 4011 arches is greater than that of the second slot 1021, and it will deform and press against the second slot 1021 after insertion, making it easier to insert.

[0042] Preferably in this embodiment, empty slots 4021 are provided at positions corresponding to the inserts 4011 on both sides of the bending piece 402.

[0043] With such a setting, the inserts 4011 can be directly formed by cutting and bending from the bending piece 402, and empty slots 4021 will be left at the positions after taking the material, which is easier to process and saves costs.

[0044] Preferably in this embodiment, the terminal block body 1 is provided with a parallel connection area 105 and an independent area 106, and the parallel connection piece 4 is located in the parallel connection area 105.
