Based on the above scheme, compared with the prior art that the first ends of the first wiring board 1 and the second wiring board 2 are locked by the zero fittings, in the scheme, the first ends of the first wiring board 1 and the second wiring board 2 are connected by an integrated forming mode, so that the vibration resistance between the first wiring board 1 and the second wiring board 2 can be improved, meanwhile, the stability of a wire in the plugging process of the plugging cavity 11 can be ensured, and the contact resistance and the service life of a product can be better controlled; the first connecting part 3 connected to the second end of the first wiring board 1 is horizontally abutted to the second connecting part 4 connected to the second end of the second wiring board 2, the inner side surface of the first connecting part 3 is abutted to the inner side surface of the second connecting part 4, meanwhile, the second connecting part 4 further comprises a turnover part 5 capable of being turned over, the turnover angle of the turnover part 5 is 180 degrees, the turnover part 5 is originally positioned on the same horizontal line with the second connecting part 4, when the turnover part 5 is turned over for 180 degrees, the first connecting part 3 can be spliced on the same horizontal line, a wire is placed on the first connecting part 3 and the turnover part 5, and as the two parts are fully contacted with the wire cores of the wire, the average distribution of current conduction can be realized, and the conducting effect is better; meanwhile, in order to ensure the stability of the terminal assembly in the use process, the turnover part 5 is locked in a clamping manner when being spliced with the first connecting part 3, the clamping is in interference fit, and therefore the turnover part 5 can be stably locked on the horizontal plane of the first connecting part 3 after being turned over, and the relative positions of the turnover part 5 and the first connecting part are kept consistent.

Preferably, the first connecting portion 3 is provided with a clamping portion 6 protruding from one side of the turnover portion 5, and the turnover portion 5 is provided with a clamping groove matched with the clamping portion 6. The first connecting portion 3 is stable, and after the turnover portion 5 turns over, the clamping groove clamps the clamping portion 6 from top to bottom, and after the clamping portion 6 clamps, the clamping portion 6 and the clamping groove are in interference fit, so that movement is difficult to occur, the turnover is avoided under non-active consciousness, and the turnover portion 5 is guaranteed to be always kept in a stable locking state after the turnover.

In addition, the setting positions of the clamping part 6 and the clamping groove can be interchanged, namely, the clamping groove is arranged on the first connecting part 3, and the clamping part 6 is convexly arranged on the turnover part 5.

Specifically, as shown in fig. 2, the engaging portion 6 is dovetail-shaped. The clamping portion 6 is of a convex dovetail structure, the clamping groove is of a corresponding concave dovetail structure, and the clamping portion 6 and the clamping groove in the dovetail shape are matched and clamped more stably. The specific structures of the clamping part 6 and the clamping groove can be in other shapes, such as ellipse, T-shape and the like, and only the turnover part 5 needs to be folded and then can be stably clamped and locked, so that the specific structures are not repeated.

In some embodiments, the first wiring board 1 and/or the second wiring board 2 are provided with a retaining groove 7. The retaining groove 7 is mainly used for being connected and fixed with electrical equipment in a matched mode, namely the whole terminal assembly can be hung on the electrical equipment through the retaining groove 7, in the scheme, the retaining groove 7 is formed in the outer surface of the first wiring board 1 and is close to the first end of the first wiring board 1, the retaining groove is far away from the first connecting portion 3, contact between a wire and the first connecting portion 3 and contact between the wire and the turnover portion 5 are not affected, and stability of fixing through the retaining groove 7 can be guaranteed. In addition, the setting of the retaining groove 7 can reduce externally hung spare and accessory parts, and enables the client application to be more open, and retaining and limiting can be performed in various modes.

It should be noted that the positions and the number of the retaining grooves 7 can be adjusted according to actual requirements, the retaining grooves 7 can be respectively arranged on the outer surfaces of the first wiring board 1 and the second wiring board 2, and can also be selectively arranged on the outer surfaces of the first wiring board 1 or the second wiring board 2, and the retaining grooves 7 are preferably arranged on the outer surfaces of the first wiring board 1 and the second wiring board 2 according to different installation requirements, so that more retaining grooves 7 can be selectively arranged. The number of the retaining grooves 7 is at least two parallel retaining grooves 7 arranged on the same outer surface, the two retaining grooves 7 are arranged in parallel and at intervals, and the purpose of arranging the two retaining grooves 7 is to stabilize the installation.

Optionally, a reed 12 is disposed in the socket 11. The spring 12 is inserted into the insertion cavity 11 and contacts with the inner side surfaces of the first wiring board 1 and the second wiring board 2 respectively, wherein the contact point is a contact point, and current flows from the first wiring board 1 into the second wiring board 2 or flows from the second wiring board 2 into the first wiring board 1 through the contact point.

Further, the outer surfaces of the first wiring board 1 and the second wiring board 2 are provided with corresponding guide grooves 8, and the guide grooves 8 extend to the inner side walls of the first wiring board 1 and the second wiring board 2 to form supporting protrusions 13 corresponding to the reeds 12. Since the reed 12 is in a wavy-like structure, the whole reed 12 is concave-convex alternately, when a lead or other terminals are inserted into the inserting cavity 11, the reed 12 is inevitably deformed greatly against one side of the lead or other terminals, and the reed 12 is easy to damage, so that in order to avoid damage to the reed 12, the supporting protrusions 13 formed on the inner side surfaces of the first wiring board 1 and the second wiring board 2 can be abutted with the reed 12 to play a supporting and protecting role, excessive deformation of the reed 12 is avoided, current conduction stability of the reed 12 is ensured, and the service life of the reed 12 is prolonged.

In addition, the outer surfaces of the first wiring board 1 and the second wiring board 2 are also provided with corresponding limit grooves 9, and the limit grooves 9 extend to the inner side walls of the first wiring board 1 and the second wiring board 2 to form limit protrusions 14 for limiting the mounting stroke of the reed 12. A smaller channel than the plug cavity 11 is formed between the two symmetrical limit protrusions 14, and the two symmetrical limit protrusions mainly have two functions, namely, the two symmetrical limit protrusions limit the installation position of the reed 12, when one end of the reed 12 is abutted against the limit protrusion 14, the reed 12 cannot move continuously, the phenomenon that the installation position of the reed 12 in the plug cavity 11 is deviated is avoided, or the reed 12 occupies excessive space in the plug cavity 11; the other is that the space of the two limiting protrusions 14 is smaller than that of the plugging cavity 11, so that the two limiting protrusions 14 can clamp wires or terminals when the wires or terminals are plugged in, and a better fixing and vibration preventing effect can be achieved.

As shown in fig. 1, the connection line of the corresponding points of the first end and the second end of the first wiring board 1 is used as a first direction, the horizontal direction perpendicular to the first direction is used as a second direction, and the plugging cavity 11 has at least one opening in the second direction. The wire is inserted into the insertion cavity 11 from the opening, at least one opening is required to be provided for inserting the wire, and the preferred scheme is to provide two openings symmetrically in the second direction, namely, two openings are provided, one of the two openings can be selected for inserting the wire, and the wire can also be inserted from one opening and can pass through the other opening.

It should be noted that the opening is formed on the basis of the integral structure of the first ends of the first wiring board 1 and the second wiring board 2, and the plugging cavity 11 is in a sealed state in the first direction, so that the opening is required to be formed in the second reverse direction.

Alternatively, the second end of the first wiring board 1 extends vertically toward the second wiring board 2 to form an extension portion 10, and the extension portion 10 is connected vertically to the first connection portion 3 in a direction away from the second end. Since the first wiring board 1 and the second wiring board 2 are disposed at intervals in the horizontal direction between the first end and the second end, in order to ensure that the first connection portion 3 and the second connection portion 4 can be stacked together in contact, it is necessary to provide an extension portion 10 between the first connection portion 3 and the second end of the first wiring board 1, and the first connection portion 3 is allowed to complete translation in the vertical direction by the extension portion 10, and thus can be stacked above the second connection portion 4.

Preferably, the lengths of the first connecting portion 3 and the turnover portion 5 in the horizontal direction are consistent, and the ratio of the lengths of the first connecting portion 3 and the second connecting portion 4 in the horizontal direction is 1:2. Taking the horizontal length in the first direction as an example, the length ratio of the first connecting part 3 to the turnover part 5 to the second connecting part 4 is 1:1:2, the lengths of the first connecting part 3 and the turnover part 5 are equal, when the turnover part 5 is horizontally spliced with the first connecting part 3, the lengths of the turnover part 5 and the turnover part are consistent with the length of the second connecting part 4, so that the integrity is stronger, and the lengths of the turnover part 5 and the first connecting part 3 are the same, so that the current average distribution can be ensured.

It should be noted that, the turnover part 5 is hinged to the second connecting part 4 through a rotation shaft, and the turnover part 5 can turn over relative to the second connecting part 4 by taking the rotation shaft as a fulcrum.
