Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Furthermore, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 1-5, an embodiment of the present invention provides a wiring system that can be used to connect two modular independent circuit modules (such as existing circuit boards, power systems, or other modules that are connected or externally connected by wires/lines).

The wiring system comprises a first electric wire 100, a second electric wire 300 and a wiring device 500 capable of detachably (electrically) connecting the two, so that the wiring device 500 can realize quick installation connection of a circuit between two circuit modules to be connected.

The first wire 100 is an overhanging wire of the first circuit module 200, and one end thereof is connected to the first circuit module 200, and the other end thereof forms a bare first core terminal 101.

The second wire 300, which is an overhang wire of the second circuit module 400, has one end connected to the second circuit module 400 and the other end forming a bare second core terminal 301.

The wiring device 500 includes an outer sleeve 501, a conductive docking pipe 502 disposed inside the outer sleeve 501, and a compression assembly 503 disposed on the outer sleeve 501.

The first wire core end 101 and the second wire core end 201 penetrate into the conductive butt joint pipe 502 from two ends of the outer sleeve 501 respectively, and are pressed and fixed through the pressing component 503, so that quick installation and connection of a circuit between two circuit modules to be connected can be achieved.

Specifically, the main body of the outer sleeve 501 is a hollow tube structure, and two ends of the outer sleeve are respectively provided with a first threading opening 501a and a second threading opening 501 b.

The conductive butt joint pipe 502 is fixed on the inner side wall of the outer sleeve 501 in a fitting manner, a butt joint channel 502a which is longitudinally communicated is arranged in the conductive butt joint pipe 502, and the first threading opening 501a and the second threading opening 501b are respectively aligned to two ends of the butt joint channel 502 a.

The docking channel 502a includes a docking section 502a-1 in the middle and a first plug section 502a-2 and a second plug section 502a-3 at the two ends of the docking section 502a-1, respectively. The docking section 502a-1 has a smaller inner diameter than the first plug section 502a-2 and the second plug section 502 a-3.

The first core tip 101 can pass through the first plugging section 502a-2 from the first threading opening 501a and enter the docking section 502 a-1; the second core end 301 can pass through the second plugging section 502a-3 from the second threading opening 501b and enter the docking section 502 a-1; the pressing component 503 can penetrate through the outer sleeve 501 and the conductive butt joint pipe 502, and respectively form lateral extrusion on the penetrated first wire core end 101 and the penetrated second wire core end 301, so that the wire core ends are fixed after penetrating into the conductive butt joint pipe 502.

The clamping assembly 503 of the present invention has the function of laterally pressing and fixing the end of the wire core inserted into the conductive butt joint pipe 502, for example: the compression assembly 503 may be a laterally fixed bolt that may be passed through the outer sleeve 501 and the conductive interface tube 502 in sequence and compressed against the end of the wire core that is passed through the conductive interface tube 502.

The conductive interface tube 502 is made of a metal (copper, aluminum, etc.) having excellent conductivity, and therefore, the first and

second core terminals

101 and 301 may or may not be butted against each other in the butting section 502 a-1. The outer sleeve 501 is made of an existing insulating material.

Further, the pressing assembly 503 of the present invention includes a first linkage set 503a and a second linkage set 503b which are symmetrically arranged, and an adjusting member 503c connected therebetween.

The first linkage group 503a includes a plurality of extrusion blocks L-1 hinged on the outer sleeve 501 and distributed along the circumferential direction, a slip ring L-2 slidably sleeved on the periphery of the outer sleeve 501, a plurality of connection blocks L-3 hinged between each extrusion block L-1 and the slip ring L-2, and a plurality of screws L-4 fixed on the outer side surface of the slip ring L-2.

The extrusion block L-1 is of a bent structure, the middle position of the extrusion block L-1 is hinged on the outer sleeve 501 and penetrates through the outer sleeve 501 and the conductive butt joint pipe 502; the inner end of the extrusion block L-1 has an inclined tendency of bending and approaching towards the butt joint section 502a-1, and the inner end is provided with a layer of friction cushion layer L-11 for extruding and compacting the inserted wire core end to provide stronger anti-falling friction force; the outer end of the extrusion block L-1 extends out of the outer sleeve 501.

The slip ring L-2 is a ring-shaped structure, which is sleeved on the outer sleeve 501 and can slide linearly on the outer sleeve 501 along the longitudinal direction.

One end of each connecting block L-3 is hinged with the exposed outer end of the corresponding extrusion block L-1, the other end of each connecting block L-3 is uniformly hinged on one side surface of the sliding ring L-2, and the screw rod L-4 is integrally formed on the other side surface of the sliding ring L-2.

Two screws L-4 are preferably uniformly distributed on the slip ring L-2.

The second linkage group 503b and the first linkage group 503a have the same structure (not described herein), and the screws L-4 of the two are opposite to each other and are connected through a corresponding adjusting member 503 c.

The adjusting member 503c has a hollow sleeve structure, and has a first female threaded end 503c-1 and a second female threaded end 503c-2 with opposite thread directions on the inner sidewalls of the two ends. The first internal thread area end 503c-1 is in threaded engagement with the screw L-4 of the first linkage group 503a, and the second internal thread area end 503c-2 is in threaded engagement with the screw L-4 of the second linkage group 503 b. Therefore, when the adjusting member 503c is rotated, the screws L-4 of the first linkage group 503a and the second linkage group 503b can synchronously move in opposite directions (simultaneously move closer to or simultaneously move away from).

When the adjusting member 503c is rotated and the slip rings L-2 of the first linkage group 503a and the second linkage group 503b move towards each other, the two slip rings L-2 can respectively pull the respective extrusion blocks L-1 through the respective connection blocks L-3, and the friction pads L-11 of the respective extrusion blocks L-1 can be tightly pressed on the wire core end penetrating into the conductive butt joint pipe 502.

The symmetrical design of the pressing assembly 503 ensures that the pressing forces of the two pressing blocks L-1 to the wire core ends at the two ends are almost the same; and because the inclined orientation design of the inner end of the extrusion block L-1 ensures that the wire core end inserted into the conductive butt joint pipe 502 is pulled outwards, the extrusion block L-1 has stronger extrusion force on the wire core end, and therefore, the self-compact structure can be formed. The process of threading the core ends inward into the conductive interface tube 502 is not hindered.

Therefore, the wiring device 500 of the present invention can realize the quick connection of the overhanging wire ends of the two circuit modules, and can ensure the firmness and stability of the connection between the two circuit modules, so that the quick connection between the modules in the cabinet to which the wiring device is applied can be correspondingly ensured, and the further optimization of the modular design of each device in the cabinet system is realized.

It should be noted that: when two modules are connected to each other by two (or three) wires, 2 (or 3) wiring devices 500 are required to be connected and fixed to each other.
