DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] This embodiment provides a cable quick connector, which can realize the quick connection of at least two cables, wherein the cables are conductor cables such as power cables or electrical signal cables.

[0026] See also Figure 1-Figure 4 The cable quick connector of this embodiment includes a shell component 1 and a connecting body component 2.

[0027] The housing assembly 1 is an insulating housing, such as an engineering plastic housing, which is used to provide a structural support foundation and a protective foundation for the cable quick connector of this embodiment.

[0028] At least two plug-in channels 111 are disposed at the housing component 1 . In this embodiment, the plug-in channels 111 are short tubular structural features integrally formed at the housing component 1 and connected to the inner and outer sides of the housing component 1 .

[0029] The connecting body component 2 at least includes a clamp 21 and a connecting bridge 23, both of which are conductors; wherein the clamp 21 is made of metal (such as copper alloy, stainless steel or aluminum alloy with high electrical conductivity) and has an annular structure, and the connecting bridge 23 is also made of metal (such as copper alloy, stainless steel or aluminum alloy with high electrical conductivity) and has a strip plate structure; at least a portion of the connecting bridge 23 is located in the inner ring of the clamp 21.

[0030] The connecting body component 2 is accommodated in the outer shell component 1 , and all the plug-in channels 111 of the outer shell component 1 are aligned with the inner ring of the clamping member 21 of the connecting body component 2 .

[0031] The cable can be plugged into the plug-in channel 111 and enter the housing assembly 1, and the cable core can reach the inner ring of the clamping member 21 of the connecting body assembly 2. When the cable quick connector is switched to the connected state, the space between the clamping member 21 and the connecting bridge 23 is narrowed to compress the cable core through the clamping member 21 and the connecting bridge 23.

[0032] Specifically, the connecting body component 2 is configured with a plurality of fastening members 21. In the present embodiment, the connecting body component 2 is configured with two fastening members 21. Correspondingly, the outer shell component 1 is configured with two plug-in channels 111. Each plug-in channel 111 of the outer shell component 1 is respectively aligned with the inner ring of a fastening member 21 of the connecting body component 2; the connecting bridge 23 is arranged across the inner rings of each fastening member 21.

[0033] More specifically, the connecting body assembly 2 further includes an external threaded member 22. In this embodiment, the external threaded member 22 is a hexagon socket screw. In other embodiments, the external threaded member 22 may also be other types of screws; see Figure 3, a threaded hole 221 is formed on one side wall of the clamping piece 21; the external threaded piece 22 passes through the threaded hole 221 of the clamping piece 21, and it can be understood that the two are threadedly matched with each other; when the external threaded piece 22 is locked, the cable quick connector is switched to the connection state. At this time, the external threaded piece 22 presses against the connecting bridge 23, so that the connecting bridge 23 moves toward the side wall of the clamping piece 21 relative to the threaded hole 221, so that the space between the clamping piece 21 and the connecting bridge 23 is narrowed.

[0034] Furthermore, a plurality of stinger structures 231 are arranged on one side of the connecting bridge 23 that contacts the core of the cable; in the present embodiment, a plurality of small quadrangular pyramid-shaped stinger structures 231 are arranged on one side of the connecting bridge 23 that contacts the core of the cable; the stinger structures 231 are arranged at the connecting bridge 23, and the stinger structures 231 can penetrate into the core of the cable, which, on the one hand, increases the pressure exerted by the connecting bridge 23 on the core of the cable and improves the mechanical stability when the cables are connected; on the other hand, increases the contact area between the connecting bridge 23 and the core of the cable and improves the conductive / signal conduction performance when the cables are connected.

[0035] Furthermore, a guide groove 232 is configured on the side of the connecting bridge 23. In fact, the guide groove 232 is a square groove-shaped structural feature integrally formed on the side of the connecting bridge 23; the side wall of the clamping member 21 is snapped into the guide groove 232 of the connecting bridge 23 to guide the connecting bridge 23 when the connecting bridge 23 moves.

[0036] Specifically, the shell assembly 1 includes a main shell component 11 and a shell cover component 12 which is covered and fixed on the main shell component 11, wherein the main shell component 11 and the shell cover component 12 are both made of insulating materials, such as engineering plastics, the main shell component 11 is an open semi-box structure, and the shell cover component 12 is a cover-shaped structure; the plug-in channel 111 is arranged on the main shell component 11 of the shell assembly 1; the connecting body component 2 is accommodated in the main shell component 11 of the shell assembly 1.

[0037] To be more specific, the surface of the main case member 11 is concave to form a buckle groove 112, and a hook 113 is arranged in the buckle groove 112. In fact, the buckle groove 112 and the hook 113 are both integrally formed with the main case member 11; a buckle ear 121 is formed at the case cover member 12, and a button hole 122 is opened at the buckle ear 121. In fact, the buckle ear 121 and the button hole 122 are both integrally formed with the case cover member 12; when the case cover member 12 is covered on the main case member 11, the buckle ear 121 of the case cover member 12 is buckled into the buckle groove 112 of the main case member 11, and the hook 113 of the main case member 11 is buckled into the button hole 122 of the case cover member 12.

[0038] Furthermore, when the shell cover member 12 is covered onto the main shell member 11, the buckle ears 121 of the shell cover member 12 are flush with the surface of the main shell member 11, so that the surface of the entire cable quick connector has a flat structure, thereby making the shell cover member 12 difficult to be opened by mistake.

[0039] Furthermore, when the cable is plugged into the plugging channel 111 of the housing assembly 1 , the outer sheath of the cable is interference fit with the inner wall of the plugging channel 111 of the housing assembly 1 , thereby effectively improving the waterproof sealing performance between the cable and the plugging channel 111 of the housing assembly 1 .

[0040] When the cable quick connector of this embodiment is in use, while ensuring that the power is off, the ends of the two cables are stripped to expose the wire cores; the two cables are respectively plugged into the two plug-in channels 111 of the main shell component 11, and the wire cores of the cables reach the inner ring of the clamping member 21 of the connecting main body component 2, at which time, the outer sheath of the cable is interference fit with the inner wall of the plug-in channel 111 to obtain a certain waterproof sealing performance; when the external threaded member 22 is locked, the cable quick connector is switched to the connected state, at which time, the external threaded member 22 abuts against the connecting bridge 23, so that the connecting bridge 23 moves toward the side wall of the clamping member 21 relative to the threaded hole 221, so that the space between the clamping member 21 and the connecting bridge 23 is narrowed until the clamping member 21 and the connecting bridge 23 press the wire core of the cable, at which time, the needle structure 231 at the connecting bridge 23 can penetrate into the wire core of the cable, and the wire cores of the two cables can be connected through the connecting bridge 23.

[0041] The cable quick connector of the present embodiment, when the cable quick connector is switched to the connection state, the space between the clamp 21 and the connecting bridge 23 is narrowed, so that the wire core of the cable is compressed by the clamp 21 and the connecting bridge 23, so that the wire core of the cable is connected through the connecting bridge 23; the cable quick connector of the present embodiment has the excellent characteristics of reliable connection (reliable mechanical connection, not easy to loosen or dislocate, and reliable electrical connection, good conductivity), convenient operation (cable docking operation can be quickly achieved without complicated steps), low cost and good waterproof sealing performance.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
