Description

Technical Field

[0001] This invention relates to the field of junction box technology, and in particular to a slip ring type junction box and its usage method. Background Technology

[0002] In today's electrical connection field, junction boxes, as key components for circuit connection and distribution, play a crucial role in the operation of various electrical equipment due to their performance and convenience. With the increasing complexity of industrial production and the widespread application of various mobile and rotating equipment, traditional junction boxes have gradually revealed many limitations in meeting diverse and flexible demands. Furthermore, in some production lines, electrical appliances requiring relocation for power supply are no longer supported by the traditional method of dragging long power cords, which not only hinders operation but also poses significant safety hazards. Therefore, a junction box is needed to facilitate wiring.

[0003] However, currently, most junction boxes use a winding method to reel in the connecting wires. During storage, the outer layer of the connecting wires is easily damaged by the external environment, thus affecting normal use. At the same time, the connection points of the junction boxes are mostly exposed, which means that during the process of using them, the connection points may be pulled by the outside and break, thus affecting the normal use of the circuit. Summary of the Invention

[0004] This invention relates to a slip ring type junction box and its usage method. It has a reset spring plate and a pressing cylinder. After the wire is wound, the pressing cylinder is pressed into the inner cavity, and the torsion card is kept horizontal with the inner slot. The torsion card is rotated to lock it in the inner slot, thereby constraining the pressing cylinder and causing the wire to retract into the inner cavity. When the wire needs to be extended, the torsion card is rotated to release the constraint on the pressing cylinder, causing it to spring out under the action of the reset spring plate, thereby exposing the internal wire to the outside, so as to facilitate extension adjustment as needed.

[0014] In one embodiment, the method includes the following steps: 1. Insert the connector into the mating screw. Since the outer wall of the connector is threaded, it connects with the threaded through hole inside the mating screw to achieve a threaded connection. The inner wall of the connector is equipped with a connector assembly. Connect the introduced wire to the connector assembly to complete the initial wiring operation. The outer wall of the cable bundle is equipped with an annular groove. After completion, the excess wire can be wound around the cable bundle by winding to prevent the wire from becoming messy. The external wire end is led out and constrained through the wire clamping groove and the mating clamping groove. 2. After the wire is wound, press the pressing cylinder into the inner baffle, keep the torsion card horizontal with the inner slot, and rotate the torsion card to lock it in the inner slot to constrain the pressing cylinder and retract the wire into the inner baffle. When the wire needs to be extended, rotate the torsion card to release the constraint on the pressing cylinder, so that it can spring out under the action of the reset spring plate, thereby exposing the internal wire to facilitate extension adjustment as needed.

[0015] Beneficial effects In this invention, the outer sheath and inner baffle provide double protection for the internal wiring. The outer wall of the outer sheath has a wire-holding groove, and the outer wall of the inner baffle has a matching groove. After the two are connected, the wiring can be orderly introduced into the junction box, avoiding direct exposure of the wiring to the outside, reducing the risk of damage to the wiring sheath from the external environment, and extending the service life of the wiring. The cable bundle sleeve is fitted outside the pressing cylinder, and its outer wall has an annular groove, which can restrain the external connection wires. After the wiring connection is completed, the excess wiring can be wound on the cable bundle sleeve, effectively preventing the wiring from becoming messy, making the wiring layout inside the junction box more neat, and facilitating subsequent inspection and maintenance.

[0016] In addition, a torsion clip is rotatably connected in the release groove on the outer wall of the top of the pressing cylinder. The torsion clip can be inserted into the inner slot on the inner wall of the outer sheath. This locking method can effectively constrain the position of the pressing cylinder and prevent it from loosening or shifting during use, thereby ensuring the stability of the wiring plug, the docking screw, and the wiring connection, and reducing wiring failures caused by loose connections.

[0017] In addition, the reset spring plate inside the inner baffle is connected to the lower annular protrusion of the inner baffle via a spring. When the pressing cylinder is pressed down, the spring is compressed, and the reset spring plate provides a buffering effect to avoid damage to the circuit and connecting parts due to excessive pressing. When it is necessary to extend the circuit, the reset spring plate causes the pressing cylinder to spring out under the elastic force of the spring, which is convenient to operate and can ensure the reliability of the circuit connection.

[0018] In addition, the junction box has a line length adjustment function. When it is necessary to extend the line, the twisting card is rotated to release the constraint on the pressing cylinder. The pressing cylinder is then ejected outward by the reset spring plate, exposing the internal line. When a longer line is not needed, the pressing cylinder can be pressed into the inner retaining cylinder and locked by twisting the card, causing the line to retract. This flexible line adjustment method can be adjusted according to actual usage needs, improving the applicability and practicality of the junction box. Attached Figure Description

[0030] The specific usage and function of this embodiment: In this invention, the upper half of the outer shell 1 is cylindrical, and the lower half is a square disc. The lower half has through holes for installing external fixing bolts. The outer shell 1 can be fixed in a suitable installation position using bolts through these through holes. The outer sleeve 2 is a cylindrical structure with equidistant arc plates fixed on it, which cooperate with the mating ring groove 101 on the top of the outer shell 1. When the outer sleeve 2 is inserted into the outer shell 1, the arc plates are accurately inserted into the mating ring groove 101. At the same time, the pressing locking block 201 at the gap position of the arc plates of the outer sleeve 2 will slide into the opening on the inner side of the mating ring groove 101 and be locked in the locking slot 102. The trapezoidal block on the outer side of the pressing locking block 201 can enhance the locking effect and ensure that the outer sleeve 2 and the outer shell are properly locked. 1. For stable connection, insert the inner baffle 3 into the outer sheath 2. The annular protrusion on the inner wall of the outer sheath 2 mates with the inner baffle 3 for positioning. After determining their positions, use screws to pass through the corresponding holes to fix the inner baffle 3 and the outer sheath 2 together, making them a relatively stable integral structure. The inner wall of the inner baffle 3 has a constraint groove 302. The reset spring plate 303 has a disc-shaped structure, and the protrusion on its outer wall matches the constraint groove 302. Place the reset spring plate 303 into the inner baffle 3, allowing the protrusion to slide into the constraint groove 302. The reset spring plate 303 can slide smoothly within the constraint groove 302. Install a spring at the bottom of the reset spring plate 303. The bottom end of the spring is connected to the annular protrusion on the lower side of the inner baffle 3, giving the reset spring plate 303 elasticity. The reset spring plate 303 has a mating screw 304 fixedly connected to the top center. The inner wall of the pressing cylinder 4 has a threaded groove that mates with the mating screw 304. The pressing cylinder 4 is connected to the outside of the mating screw 304 by the thread. The annular protrusion on the outer side of the top of the pressing cylinder 4 can limit its position on the mating screw 304 to prevent excessive screwing in or out. The cable bundle 405 is cylindrical. The mating groove 406 on the inner wall of the cable bundle 4 mates with the rectangular protrusion on the outer wall of the pressing cylinder 4. The cable bundle 405 is fitted onto the outside of the pressing cylinder 4 so that the rectangular protrusion is inserted into the mating groove 406. The rectangular through hole at the bottom of the cable bundle 405 is aligned with the mating interface 401 of the pressing cylinder 4. The introduced wire is connected to the wiring assembly on the inner wall of the wiring plug 404 to complete the initial wiring. After wiring, the wires are led out through the outlet hole 305 of the connecting screw 304, the mating interface 401 of the pressing cylinder 4, and the rectangular through hole at the bottom of the cable bundle 405. Using the annular groove on the outer wall of the cable bundle 405, excess wire is wound onto the cable bundle 405 to keep the wires neat and orderly, avoiding tangles. Simultaneously, the external wire ends are led out and restrained through the wire clamping groove 202 and the mating clamping groove 301 to prevent the wires from loosening. After the wires are wound, the pressing cylinder 4 is manually pressed downwards into the inner stop cylinder 3. At this time, the spring at the bottom of the reset spring plate 303 is compressed. When the twisting card 403 is horizontal with the inner clamping groove 203, the twisting card 403 is rotated to lock into the inner clamping groove 203, thus restraining the pressing cylinder 4.Simultaneously, as the pressing cylinder 4 is pressed down, the wiring retracts into the inner retaining cylinder 3, reducing the exposed length of the wiring and facilitating its storage and protection. When it is necessary to extend the wiring's lifespan, rotating the twisting card 403 disengages it from the inner slot 203, releasing the constraint on the pressing cylinder 4. The reset spring plate 303 then slides upwards under the spring force, pushing the pressing cylinder 4 outwards, thus exposing the internal wiring. The usable length of the wiring can be flexibly adjusted according to actual needs.
