The specific implementation mode is as follows:

referring to fig. 1-6, in one embodiment of the present invention, a bi-directional terminal for a power distribution test terminal is provided that is easy to disassemble and can be used for wire connection on various control cabinets, analog cabinets or other electrical equipment.

The first connection module includes an external first housing 100, a first connection assembly 200 for connection, and a first rotation assembly 300 for securing an inserted wire.

Specifically, the first housing 100 may preferably have a hollow cylindrical shape, and two ends thereof are sealed to form a receiving space M therein. The two longitudinal end surfaces of the first shell 100 are respectively an inner end and an outer end, the inner end of the first shell 100 is used for being in butt joint with the second wiring module and is used for being matched with the second wiring module to carry out the integral installation and fixation of the wiring terminal, so that a through hole capable of allowing the first connecting component 200 to partially penetrate out is formed in the right center position of the inner end of the first shell 100; the outer end of the first housing 100 is an inlet through which the electric wire is inserted, and thus, a center position of the outer end of the first housing 100 has a receptacle through which the electric wire can be inserted and removed.

The first connection assembly 200 is disposed inside the first housing 100 along a longitudinal direction of the first housing 100. The first connection assembly 200 includes a first docking section 201, a first mating section 202, and a first restraint block 203 therebetween.

The first restraint block 203 is a short column with one end processed into a round angle, two end faces are a first face 203a and a second face 203b respectively, the first butt section 201 is fixed on the second face 203b, and the first plug section 202 is fixed on the first face 203 a. The edge of the second face 203b is provided with a rounded corner, and on the second face 203b, the annular region between the rounded corner and the first abutment section 201 is recessed to form an annular groove 203b-1, such that on any cross-section through the central axis of the first confinement block 203, the outer ports of the annular groove 203b-1 form a "hook". It should be noted that: the first face 203a of the first restraint block 203 is sized larger than the perforation size of the inner end of the first housing 100 such that the connection assembly 200 cannot be disengaged from the housing 100.

The first butt joint section 201 is in a rod shape, one end of the first butt joint section is vertically fixed on the second surface 203b of the first restraint block 203, and the other end of the first butt joint section is an overhanging free end which is used for directly butt joint with the inserted wire end; the first plugging section 202 is a hollow sleeve, one end of which is vertically fixed on the first surface 203a of the first constraint block 203, and the other end of which passes through a through hole on the inner end of the first housing 100.

Preferably, the central axes of the first docking section 201, the first constraining block 203 and the first plugging section 202 are collinear, and the three sections are sequentially connected, and are manufactured into an integral structure to jointly form the first connecting assembly 200. To achieve the conductive performance, the first connection assembly 200 is made of a conventional conductive metal material, such as copper, aluminum, etc. In addition, the central axis of the first connection assembly 200 coincides with the longitudinal central axis of the first housing 100, so that the first connection assembly 200 is ensured to be located at the central axis position in the first housing 100.

Further, a first elastic member 204 is disposed between the first surface 203a of the first constraining block 203 and the inner end of the first housing 100, and the first elastic member 204 is sleeved on the periphery of the first plugging section 202. The first elastic member 204 may employ a compression spring, and thus, the first coupling assembly 200 as a whole may perform a certain degree of longitudinal rectilinear motion.

From the above, it can be seen that: the external wire end can be inserted into the accommodating space M from the jack at the outer end of the first shell 100 and is in contact with the end face of the free end of the first butt joint section 201, so that the circuit of the external wire, the first butt joint section 201, the first restraint block 203 and the first plug joint section 202 is in a communicating state. Preferably, the first connecting assembly 200 can be indirectly pushed to perform a certain degree of linear motion by pushing the external electric wire inwards, and the first elastic member 204 also has a rebound effect.

However, if the electric wire is simply inserted into the insertion hole and is docked with the first docking section 201, the fixing and stabilizing effects cannot be achieved, and the electric wire still easily falls off. Thus, the inserted electric wire can be fixed by the first rotating assembly 300, so that the electric wire can be ensured to be synchronously locked by binding once inserted.

The first rotating assembly 300 is located in the accommodating space M of the first housing 100, and has a hinge point 301 thereon. The first rotating assembly 300 is hinged to the inner side wall of the first housing 100 by a hinge point 301 thereon. Specifically, at least two hinge seats 101 are uniformly fixed on the inner sidewall of the first housing 100 at the same lateral position. The accommodating space M has first rotating assemblies 300 in the same number as the hinge seats 101 and in one-to-one correspondence, and the hinge points 301 of each first rotating assembly 300 are respectively hinged to the corresponding hinge seats 101 one by one and are fixed on the inner side wall of the first housing 100 through each hinge seat 101.

Therefore, the plurality of first rotating assemblies 300 can be also understood as being obtained by annular arrays with the central axis of the first connecting assembly 200, and at least two first rotating assemblies 300 are provided (four first rotating assemblies 300 are shown in the drawings of the present invention, but the scope of protection is not limited thereto).

Further, the first rotating assembly 300 includes clamping portions 302, each of which clamping portions 302 is capable of rotating about a respective hinge point 301 and commonly clamping or unclamping the electric wire inserted from the outer end of the first housing 100. Preferably, the clamping portion 302 is formed in a bent shape, and the bending direction is the central axis direction of the first connecting component 200 (i.e. the axial direction of the wire to be inserted). In addition, the end of the clamping portion 302 further has a clamping surface 302b, and the clamping surface 302b may be made of a flexible material (such as rubber) with anti-skid and resistance-increasing properties, and when an external electric wire is inserted into the insertion hole and is abutted with the free end of the first abutting section 201, the clamping surface 302b of the clamping portion 302 can be exactly and completely abutted against the outer surface of the electric wire. When the thickness of the wire is slightly different, the clamping surface 302b is made of a flexible resistance-increasing material, so that the flexible resistance-increasing material can adapt to the space of the difference, and still can be attached to and clamped on the wire.

Further, the clamping or loosening of the electric wire by the clamping portion 302 is controlled by the following technical scheme:

the clamping portion 302 has a through chute 302a, and the chute 302a may be a rectangular through hole with a long shape, preferably, two widths of the rectangle may be replaced by a convex semicircle. In terms of spatial position, it is also necessary to ensure that: the vertical distance between one end of the chute 302a near the hinge point 301 and the central axis of the first connection assembly 200 is always greater than the vertical distance between the other end of the chute 302a and the central axis of the first connection assembly 200.

If the end of the chute 302a near the hinge point 301 is the clamping end 302a-1 and the end of the chute 302a far from the hinge point 301 is the releasing end 302a-2, the vertical distance between the clamping end 302a-1 and the central axis of the first connecting assembly 200 is greater than the vertical distance between the releasing end 302a-2 and the central axis of the first connecting assembly 200 according to the above description, that is, the trend of gradually approaching the central axis of the first connecting assembly 200 is ensured in the process from the clamping end 302a-1 to the releasing end 302a-2 in the chute 302 a.

The bi-directional terminal of the present invention further includes a first adjustment assembly 400, where the first adjustment assembly 400 includes a mating portion 401 and a connecting portion 402, where the mating portion 401 may be a torus that sequentially passes through the chute 302a on each clip portion 302 to "string" the mating portions 401 together. The engaging portions 401 can slide in each chute 302a synchronously, and the invention can realize the adjustment of the rotation angle of the clamping portion 302 by pulling or pushing the engaging portions 401 along the direction of the central axis of the first connecting assembly 200. The specific principle is as follows: the above-mentioned "the trend of gradually approaching the central axis of the first connection assembly 200 from the clamping end 302a-1 to the releasing end 302a-2 in the chute 302 a" is that the fitting portion 401 itself does not undergo structural change during movement, and thus conversely, when the fitting portion 401 moves in the chute 302a in a direction away from the hinge point 301, the clamping portion 302 will rotate in a direction away from the electric wire and release the electric wire; when the fitting portion 401 moves in the direction approaching the hinge point 301 within the inclined groove 302a, the clamping portion 302 will rotate in the direction approaching the electric wire and clamp the electric wire.

In the above description, the movement of the engaging portion 401 along the central axis direction of the first connecting assembly 200 may be transmitted through the connecting portion 402 and the operating portion 403 at the outer end thereof. Specifically, the connection portion 402 is a longitudinally disposed rod-shaped structure, and may be disposed in parallel with a plurality of connection portions, which are disposed offset from the first rotating assembly 300. The inner end of each connecting portion 402 is fixed to the mating portion 401, while the outer end extends out from the outer end of the first housing 100 in the longitudinal direction, and is integrally fixed to the outer end of each connecting portion 402 by an operating portion 403, where the operating portion 403 may be a torus or other torus.

When the engagement portion 401 is set to be close to the release end 302a-2 in the initial state, the clamp portion 302 is in the released state. Accordingly, when the electric wire is inserted from the insertion hole at the outer end of the first housing 100 and is docked with the first docking section 201, the operating portion 403 can be pushed inward. At this time, the fitting portion 401 gradually slides closer to the clamping end 302a-1, and the clamping portion 302 gradually approaches the electric wire accordingly, and finally complete clamping is achieved. In the clamped state, it is necessary to ensure that the operating portion 403 can just contact the outer end surface of the first housing 100 or leave a gap with the outer end surface of the first housing 100, so that the operating portion 403 can have a margin for the insertion movement. When the electric wire needs to be loosened, the operating portion 403 can be pulled outward. At this time, the fitting portion 401 gradually approaches the releasing end 302a-2, and the clamping portion 302 gradually gets away from the electric wire, eventually achieving complete release.

Preferably, to accommodate the thickness differences between different wires, a spare length may be reserved for chute 302a (i.e., the length of chute 302a is set longer) in preparation for clamping smaller sized wires. Namely: no matter when the clamping portion 302 clamps or unclamps the wire, the mating portion 401 cannot slide completely within the chute 302a to the clamping end 302a-1 or the unclamping end 302a-2, which ensures that the clamping portion 302 has a larger reserved rotational space.

Further, the inner side wall of the first housing 100 is fixed with the rebound members 102 corresponding to the first rotating assemblies 300 in number and one-to-one, each clamping portion 302 corresponds to one rebound member 102, and the outer end of each rebound member 102 abuts against the outer edge of the corresponding clamping portion 302. The resilient member 102 may be a spring having a deformation and rebound ability, and the resilient member 102 can maintain the clamping effect of the clamping portion 302 on the electric wire and prevent loosening of the electric wire after the fitting portion 401 approaches the clamping end 302a-1 and causes the clamping portion 302 to clamp the electric wire.

Further, the first rotating assembly 300 further has a force receiving portion 303, where the force receiving portion 303 is disposed at the other end of the hinge point 301 with respect to the clamping portion 302. Thus, the first rotating assembly 300 is divided into two sections, a clamping portion 302 and a force receiving portion 303, respectively, by the middle hinge point 301. The force receiving portion 303 is used to assist and optimize the clamping and releasing effects (i.e., to enhance and maintain the clamping effect, maintain the releasing state) of the clamping portion 302 on the electric wire.

The outer edge of the force receiving portion 303 is a plane, while the inner edge is a curved surface, and the end of the force receiving portion 303 is formed as a tip. When each first rotating member 300 is rotated synchronously and the tips of the force receiving portions 303 thereof are hooked in the annular groove 203b-1 of the first restraining block 203, the outer side edges of the tips of the force receiving portions 303 will press the outer side wall of the annular groove 203b-1 due to the pressing of the resilient member 102. Meanwhile, since the first elastic member 204 can press the first constraint block 203 to make it have a tendency to move toward the first rotating assembly 300, the annular groove 203b-1 can buckle the tip of each stress portion 303, limit the rotation of the stress portion 303, and maintain the clamping portion 302 in a loose state, so as to facilitate the extraction of the electric wire or the unobstructed insertion of a new electric wire.

When the tip of each of the force receiving portions 303 is disengaged from the annular groove 203b-1, the rounded edges of the second face 203b can contact and press the inner edges of the tips of each of the force receiving portions 303, also due to the pressing of the first restriction piece 203 by the first elastic member 204. Since the inner edge of the tip is curved, when the first constraint block 203 presses the force receiving portions 303, each force receiving portion 303 has a tendency to be "spread apart" and away from the central axis of the first rotating assembly 300, and the clamping portion 302 has a tendency to clamp the electric wire. In this way, the clamping portions 302 of the respective first rotating assemblies 300 can clamp the electric wires together, enhancing and maintaining the clamping effect.

It should be noted that the first elastic member 204 is in a compressed state during any of the above processes, so that the clamping effect or the releasing state of the clamping portion 302 can be maintained all the time.

The bidirectional binding post comprises a first binding module and a second binding module which are symmetrically arranged, wherein the inner ends of the first binding module and the second binding module can be mutually butted and jointly clamp a panel of electrical equipment, the panel is installed and fixed through screw and nut combination, and corresponding installation holes are formed in the panel to allow the panel and the panel to be in butt joint contact. The outer end of the first wiring module and the outer end of the second wiring module can be directly inserted into the electric wire, and the lines at two ends of the bidirectional wiring terminal can be quickly connected.

The second wiring module is symmetrically disposed with the first wiring module, and also includes a corresponding second housing 500, second connection assembly 600, and second rotation assembly 700. It should be noted that: any structure of the first wiring module except the first plugging section 202 is identical to the second wiring module, and is symmetrically arranged about the abutting contact surface of the first wiring module and the second wiring module.

Specifically, the second housing 500 and the first housing 100 have identical and symmetrical structures, and inner ends of the two are opposite to each other. The second housing 500 and the first housing 100 have perforations at the right center of the inner ends, and after the inner ends of the second housing 500 and the first housing 100 face each other, the perforations at the inner ends of the two can face each other to form communication. The first mating segment 202 can then pass through the perforations in communication formed by the first housing 100 and the second housing 500 in sequence after mating.

Further, the first plugging section 202 is a hollow sleeve, and a slot 202a is recessed in an end surface thereof. The second connector assembly 600 has a second mating segment 602 that is structurally different from the first mating segment 202 (any structure of the first wiring module other than the first mating segment 202 is identical to the second wiring module). The second mating segment 602 has a cylindrical configuration that mates with the socket 202a and is capable of being inserted into the socket 202a with a relative withdrawal movement.

The other end of the second plugging section 602 has a second docking section 601 with the same structure as the first docking section 201, and the second docking section 601 reversely extends into the second housing 500 relative to the second plugging section 602 for docking with an end of an electric wire penetrating from the outer end of the second housing 500.

Further, a second constraint block 603 is also disposed between the second docking section 601 and the second plugging section 602, the second constraint block 603 has the same structure as the first constraint block 203, and a second elastic member 604 is also disposed between the second constraint block 603 and the inner end of the second housing 500, and the second elastic member 604 is sleeved on the periphery of the second plugging section 602. The second elastic member 604 may employ a compression spring.

The second rotating assembly 700 is identical in structure to the first rotating assembly 300 and is symmetrically disposed. In addition, the second wiring module also includes a second adjusting assembly 800 symmetrically arranged and configured with the first adjusting assembly 400. Because the second wiring module has the same structure as the first wiring module, the present invention is not repeated based on fig. 1.

Since the working principle and the operation process of the first wiring module and the second wiring module are consistent, the invention can only explain the use mode of the first wiring module as follows:

when set in the initial state, the tip of the force receiving portion 303 is restrained in the annular groove 203b-1, and the engaging portion 401 is close to the released end 302a-2, with the holding portion 302 in the released state.

If an external wire is needed, part of the fiber core of the wire end can be exposed in advance (the wire end is not needed to be treated too much and only needs to be exposed and visible); the wire is inserted through the insertion hole at the outer end of the first housing 100 and is docked with the free end of the first docking section 201.

After the electric wire is butted with the first butting section 201, the electric wire is pushed inwards continuously, so that the whole first connecting assembly 200 butted with the electric wire moves inwards, and finally the tip of the stress part 303 is separated from the annular groove 203b-1; when the tip of the force receiving portion 303 is not constrained by the annular groove 203b-1, the resilient member 102 can press the clamping portion 302 effectively, so that it rotates in the wire direction.

After pushing the first connecting assembly 200, the wire stops pushing. After the tip of the force receiving portion 303 is separated from the annular groove 203b-1, the first restriction piece 203 can press the inner edge of the force receiving portion 303, so that the clamping portion 302 can rotate in a direction approaching the electric wire. Thus, the first restraint block 203 cooperates with the resilient member 102 to enable the respective clamping portions 302 to rotate together and clamp the wire.

During the rotation of the first rotating assembly 300, the engaging portion 401 also adaptively and automatically moves along the chute 302a toward the clamping end 302a-1 (i.e., the first adjusting assembly 400 moves into the accommodating space M). Of course, if the first restraint mass 203 cooperates with the rebound member 102 not yet sufficiently to cause adaptive movement of the first adjustment assembly 400, the operating portion 403 may be manually pushed inwardly.

When the electric wire needs to be pulled out, the electric wire needs to be pushed first to jack up the first connecting assembly 200 inwards so as not to obstruct the subsequent rotation stroke of the stressed portion 303, then the first adjusting assembly 400 is pulled out outwards so that the tip of the stressed portion 303 rotates towards the direction close to the central axis of the first connecting assembly 200 until the tip of the stressed portion 303 is embedded into the annular groove 203b-1, then the electric wire stops being pushed, and then the rebound first restraining block 203 can be buckled on the tip of the stressed portion 303 to form restraint. At the same time, the clamping portion 302 releases the electric wire and maintains the released state, i.e., the electric wire can be pulled out.

If the external electric wire is required to be thinner and has low strength, the pushing member 900 can be used to push the first connection assembly 200. The pushing member 900 may be a hollow circular tube with a longitudinal slit, i.e. a longitudinal opening is cut on the side of a hollow tubule along the direction of the generatrix, so as to obtain the pushing member 900. The "longitudinal opening" is a through slot from which the wire can be inserted into the hollow channel of the barrel. In use, the electric wire is inserted into the pushing member 900, so that the pushing member 900 is inserted into the insertion hole at the outer end of the first housing 100 together with the electric wire, and the first connecting assembly 200 is pushed by the pushing member 900, when the clamping portion 302 starts to clamp the pushing member 900 in a closing manner, the electric wire is kept still, the pushing member 900 is pulled out, and finally the clamping portion 302 can clamp the electric wire. To facilitate extraction of the pusher 900, the inner and outer surfaces of the pusher 900 may be provided with smooth surfaces to reduce friction. The ends of the holding surfaces 302b may be rounded, when the wires need to be pulled out, the wires exposed outside may be first inserted into the pushing member 900, and then the pushing member 900 is inserted into the insertion hole at the outer end of the first housing 100 along the wire direction, and is extruded into the middle of each holding surface 302b from the opening formed by the rounded ends of each holding surface 302b, which is not described herein.

In practice, the push member 900 is rarely used, and the wiring process can be completed by directly inserting the electric wire. Because the use mode of the bidirectional binding post and the butt joint mode of the electric wire determine that the electric wire end does not need to be treated excessively, the electric wire end only needs to be exposed and visible, namely: the wire to be inserted can be processed by only processing the end of a little fiber core, and a large amount of wire sheath is not required to be pulled out, so that the wire with the wire sheath has enough strength and toughness to directly push the first connecting component 200 to displace.

The working principle and the operation process of the second wiring module are consistent with the above.

It should be noted that, from the above, it is known that: the first connecting assembly 200 and the second connecting assembly 600 can perform longitudinal linear motion, the second plugging section 602 can also perform plugging motion in the slot 202a of the first plugging section 202, and the structural characteristics not only can ensure that the second constraint block 603 and the first constraint block 203 respectively clamp or loosen wires at two ends, but also have the following synergistic effect:

as shown in fig. 1, if an electric wire is inserted from the outer end of the second housing 500 and is butted with the second butting section 601, so as to achieve the clamping state as shown in fig. 3, in which the second constraint block 603 presses the second rotating assembly 700, and the second rotating assembly 700 clamps the electric wire, the second wiring module is used for connecting and stabilizing the electric wire, and the principle and process are the same as those of the first wiring module, which is not repeated here. At this time, if the electric wire is inserted into the outer end socket of the first housing 100 and the first connection assembly 200 is pushed inward, not only the rotation stroke of the first rotation assembly 300 can be activated, but also the movement of the first plugging section 202 generates sliding friction on the second plugging section 602, and the second restraint block 603 also has a tendency to press the second rotation assembly 700 more greatly, so that the electric wire clamped by the second rotation assembly 700 is tightly pressed.

The mounting and fixing mode of the bidirectional binding post is as follows:

the panel of the electrical equipment to be mounted is provided with a mounting hole, the inner ends of the first shell 100 and the second shell 500 are aligned to the center of the mounting hole from two sides of the mounting hole respectively, and the through holes on the inner ends of the first shell 100 and the second shell 500 are opposite to each other, and when the two shells are in butt joint, the tail end of the second plug section 602 can be just inserted into the slot 202a of the first plug section 202.

In addition, the outer edge of the inner end of the first housing 100 has a transverse circle of the first fixing ring 103, and the outer edge of the inner end of the second housing 500 has a transverse circle of the second fixing ring 505. The first fixing ring 103 and the second fixing ring 505 are in the same shape and size, are symmetrically arranged, and are all circular edge structures. The bi-directional binding post is fixed and installed through the clamping of the first fixing ring 103 and the second fixing ring 505 to the two side edges of the installation hole, and finally, one circle of the first fixing ring 103 and the second fixing ring 505 can be fixed on the panel through a plurality of screw and nut combinations (of course, corresponding round holes are formed in the first fixing ring 103, the second fixing ring 505 and the panel for inserting screws).

In summary, the bidirectional binding post of the invention omits a plurality of complicated steps of wiring, winding and fixing and clamping during wiring, and omits the process of manually peeling off the longer wire skin, so that the wiring is very simple and convenient, the connection of the circuit can be realized by directly inserting the wire end by a user, and the stability of the connection can be ensured. To ensure the safety of the bi-directional terminal, the first housing 100, the first rotating member 300, the first adjusting member 400, and the second housing 500, the second rotating member 700, the second adjusting member 800, and the pushing member 900 are all made of insulating hard materials, such as plastic.

The present invention is not described in detail in the present application, and is well known to those skilled in the art. Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
