The present application is described in detail below with reference to the figures and alternative embodiments.

Fig. 1 is a schematic structural diagram of a terminal block according to an embodiment of the present application, and as shown in fig. 1, the present application discloses a terminal block 10 for connecting compensation wires, where the terminal block 10 includes a base 400 and at least two terminals 700 disposed on a surface of the base 400, and at least every two terminals 700 are terminal groups, all the terminals 700 in each terminal group are conducted with each other, and each terminal 700 is connected to one compensation wire to conduct two corresponding compensation wires; each of the terminal groups is insulated from each other, the base 400 may be made of an insulating material, such as ceramic, and of course, the insulating material may be directly disposed between the terminals 700 and the base to prevent the terminals 700 of different groups from being conducted, and each of the terminal groups may be disposed around the side of the base.

Compared with the scheme that only one side of the base body 400 is provided with the wiring terminal 700 in the prior art, the wiring terminal 700 of each group is arranged on the side face of the base body 400 in a surrounding mode, so that more wiring terminals 700 can be arranged on the base body 400, the number of wire harnesses in equipment is more or less, the number of the wiring terminals 700 which can be connected by the wiring terminal row 10 designed by the application is more, and the application range is wider.

Specifically, the shape of the base 400 includes a cylinder with a hollow inside, but the shape of the base 400 is not limited to a cylinder, and may be a prism, such as a triangular prism, a quadrangular prism, a pentagonal prism, and the like, and also not limited to a shape with a hollow inside, and the shape of the base 400 is explained as a cylinder with a hollow inside.

The side of the base 400 is provided with a plurality of isolation grooves 600, the isolation grooves 600 penetrate through the upper surface and the lower surface of the base 400, and the wiring terminals 700 in each group are all arranged in the same isolation groove 600. And the height of the wiring terminal 700 does not exceed the notch of the isolation groove 600, the upper surface of the wiring terminal 700 far away from the substrate 400 is lower than the outer surface of the substrate 400, so that the problem that when the wiring terminal block 10 touches an external metal conductor, the external metal conductor touches different assembly wiring terminals 700, and the conduction of the different assembly wiring terminals 700 is caused is avoided. For example, when the terminal block 10 is disposed in a pipe, the terminal block 10 is disposed coaxially with the pipe since the height of the terminal block 700 does not exceed the notch of the isolation groove 600; even if the terminal block 10 contacts with the inner wall of the pipe, the pipe only contacts the substrate 400, and does not contact the terminal block 700, so that the conduction of different groups of terminal blocks 700 is avoided.

Fig. 2 is a front view of a terminal block according to an embodiment of the present application, and as shown in fig. 1 and 2, the isolation grooves 600 are circumferentially equidistantly formed around the side surface of the base 400. Therefore, each of the isolation grooves 600 is located at the same distance from the axis of the hollow cylindrical base 400, and in practical use, the electrical device generally includes a plurality of compensation wires within one wire harness, and when the compensation wires are connected, the length of each of the compensation wires from the device to the terminal block 10 is the same, and there is no error between different compensation wires due to the difference in length. When the terminal block 10 arranged in rows in the prior art is connected, if the length of each compensation wire is the same, the stress of each compensation wire is different, and the compensation wire with too large stress is easy to be separated from the terminal block 700; in order to make the stress of each compensation wire the same, there will be different lengths of the compensation wires, and there will be an error between the compensation wire with a longer length and the compensation wire with a shorter line. And this application binding post row 10 sets up the equidistance through the base member 400 that sets up the cylinder shape in the side of base member 400 and encircles the binding post 700 of base member 400 for the distance of the compensation wire of connecting on binding post 700 to the sinle silk is the same, can not have the error, and the atress of every compensation wire all equals, and the condition that the compensation wire breaks away from binding post row 10 can not take place.

As shown in fig. 2, a compensation tab 200 is further disposed in the isolation slot 600, and the compensation tab 200 is disposed on the connection terminal 700 and is used for conducting a group of connection terminals 700 corresponding to the isolation slot 600; the material of the compensating press piece 200 is the same as that of the compensating wire. And a compensating spacer 300 is disposed between the compensating pressing sheet 200 and the base 400, the compensating conductor is fixed by vertically clamping the compensating conductor by the compensating pressing sheet 200 and the compensating spacer 300, and the material of the compensating spacer 300, the material of the compensating pressing sheet 200 and the material of the compensating conductor are the same.

Compared with the scheme that the compensation conducting wire is wound on the connecting terminal 700 in the prior art, the compensation conducting wire can be more firmly fixed in a mode that the compensation pressing sheet 200 and the compensation gasket 300 vertically clamp the compensation conducting wire, the compensation pressing sheet 200, the compensation gasket 300 and the compensation conducting wire are made of the same material, the compensation pressing sheet 200 and the compensation conducting wire further have the function of connecting two connecting terminals 700 in the same group, and the same material can avoid error loss caused by the fact that a medium is changed when the two compensation conducting wires transmit signals.

Moreover, the compensation pressing sheet 200 and the compensation gasket 300 are detachably connected with the base 400, when the equipment is replaced for connection, only the compensation pressing sheet 200 and the compensation gasket 300 need to be replaced, and the compensation pressing sheet and the compensation gasket are replaced by the compensation wire made of the same material, and the whole wiring terminal block 10 does not need to be replaced, so that the application range of the wiring terminal block 10 is wider, and the cost is reduced.
