Description

Technical Field

[0001] This invention relates to the field of cable connector technology, specifically to a cable connector and wiring method. Background Technology

[0002] In electrical wiring, it is often necessary to distribute the electrical signals or power of a main cable to multiple branch cables. The core component for achieving such a "one-to-many" connection is the cable connector. However, standard cable connectors in the prior art (such as conventional butt joints and threaded locking joints) are usually designed as a "one-to-one" connection, that is, one input end corresponds to one output end. Their fundamental function is to achieve end-to-end connection, sealing, and mechanical fixation between single cables. A typical structure is an energy-saving and waterproof cable connector disclosed in application number CN2021110363976.

[0003] When it is necessary to implement a "one-to-many" branch connection, existing technologies typically employ the following workarounds, but all of these solutions have significant drawbacks:

[0004] 1. Using multiple independent connectors: First, connect the main cable to the input of a multi-port terminal block using a one-to-one connector, then connect each branch cable to its respective output port. This is essentially a system composed of multiple independent connectors and intermediate terminals, not a single integrated connector component. Its structure is loose, it occupies a large space, requires numerous installation steps, and has many connection points, increasing the potential for malfunctions.

[0005] 2. Use of complex branching devices: Some connection devices with multiple output ports, although structurally integrated, often still rely on independent operation of each branch cable for the crimping and mechanical fixing of electrical connections. For example, multiple wire screws or clips need to be tightened one by one. This "point-by-point operation" mode fails to simplify the final installation process, has low operational efficiency, and makes it difficult to ensure the consistency and uniformity of the clamping force at all connection points. This may result in higher contact resistance at some connection points, affecting conductivity and long-term reliability.

[0006] In summary, existing technologies lack a truly integrated component that can be used as a standard "connector" to simultaneously and reliably lock the main cable and achieve stable electrical connections with multiple branch cables through a single, continuous operation. Therefore, an innovative cable connector design is urgently needed to address these issues. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the present invention provides a cable connector and wiring method.

[0008] The technical solution adopted in this invention is: a cable connector, comprising:

[0009] The main body shell has a main wire hole for cables to pass through and a plurality of secondary wire holes arranged around the main wire hole. A cavity is formed inside the main body shell that communicates with the main wire hole and all the secondary wire holes.

[0010] A conductive piece is fixedly mounted on the bottom wall of the cavity;

[0011] A clamping ring is disposed in the cavity and located above the conductive piece, and the clamping ring is connected to a linkage portion extending to the outside of the main body shell;

[0012] A locking nut is rotatably fitted onto one end of the main wire hole of the main body housing. The locking nut has a threaded part that is threaded to the main body housing, a connecting part that is connected to the linkage part, and an insertion hole through which a cable can pass.

[0013] A locking sleeve is provided inside a locking screw sleeve, and the outer wall of the locking sleeve and the inner wall of the insertion hole are provided with mutually cooperating inclined surfaces.

[0014] When the locking sleeve is rotated to screw into the main body shell, the connecting part drives the clamping ring to move towards the conductive plate through the linkage part, so as to clamp and fix the cable passing through the secondary wire hole. At the same time, the inclined structure cooperates to cause the locking sleeve to shrink radially, so as to clamp and fix the main cable passing through the main wire hole.

[0015] Furthermore, the conductive piece is provided with a first protruding ring and a second protruding ring that surround the main wire hole and are spaced apart, and the wire core of the cable passing through the secondary wire hole is pressed between the pressing ring and the first protruding ring and the second protruding ring;

[0016] The clamping ring at the secondary hole has a corresponding arc-shaped concave surface.

[0017] Furthermore, the linkage part consists of multiple linkage plates spaced apart, the linkage plates passing through the pressure groove provided on the side wall of the main body shell; the connecting part is a first annular groove provided on the locking screw sleeve, the end of the linkage plate extends into the first annular groove, and is axially limited by a mutually limiting anti-loosening structure, the linkage plate and the first annular groove can rotate relative to each other.

[0018] Furthermore, the main body shell includes an integrally structured column and a disc. The column is provided with the main wire hole, and the outer wall of the column is provided with an external thread that engages with the threaded part. The locking nut is provided with a second annular groove, and the threaded part is disposed in the second annular groove. The cavity is formed inside the disc, and the secondary wire holes are spaced apart on the outer peripheral sidewall of the disc.

[0019] Furthermore, it also includes a dustproof rubber sleeve, which is fitted onto the disk body and has rubber holes that correspond one-to-one with each secondary wire hole. The rubber holes are provided with a sealing film that allows cables to pass through.

[0020] Furthermore, the inner wall of the locking sleeve is provided with annular ridges for increasing friction, and the sidewalls of the locking sleeve are provided with notches spaced apart to facilitate radial contraction.

[0021] Furthermore, both the main wire hole and the secondary wire hole are provided with stepped rings to abut against the end of the insulating sleeve of the inserted cable.

[0022] Furthermore, the locking nut end is provided with a threaded connection section, and an operating section is provided below the threaded connection section, the outer circumferential cross section of the operating section being polygonal.

[0023] Furthermore, the shape of the disc is circular or equilateral polygonal.

[0024] This application also provides a wiring method for a cable connector, comprising the following steps:

[0025] S1. Peel off the insulation sleeve of the main cable to expose the wire core, and insert the main cable through the insertion hole of the locking screw sleeve and the main wire hole of the main body shell until the end of its insulation sleeve is limited by the stepped ring and its wire core contacts the conductive piece.

[0026] S2. Peel off the insulation sleeve of at least one secondary cable to expose the wire core, and insert each secondary cable into the corresponding secondary cable hole until the end of its insulation sleeve is limited by the stepped ring and its wire core extends into the cavity inside the second convex ring.

[0027] S3. Rotate the locking sleeve so that it screws in relative to the main body shell;

[0028] S4. During the screwing process, the locking screw sleeve drives the clamping ring to move downward through the linkage part, pressing the core of each secondary cable between the clamping ring and the bottom wall of the cavity, thereby achieving electrical connection with the conductive piece; at the same time, the inclined structure inside the locking screw sleeve forces the locking sleeve to contract radially, pressing and fixing the main cable.

[0029] The beneficial effects of this invention are:

[0030] 1. Achieves truly efficient one-to-many connection: This invention creatively integrates the "one-to-many" electrical connection function into a standard connector component. Through a single, continuous tightening of a single locking screw, the internal mechanism is simultaneously driven, completing both the mechanical locking of the main cable and the electrical connection and fixation of all branch cables. This completely changes the cumbersome process of traditional solutions requiring multiple individual operations per cable and point, greatly improving installation and maintenance efficiency, and is especially suitable for applications requiring rapid cabling.

[0031] 2. Ensures consistent and high reliability of connections: Through a unique clamping ring and linkage design, the clamping ring synchronously and evenly presses down on the cores of all branch cables during the tightening of the locking sleeving, ensuring they contact the conductive plates with a consistent clamping force. This synchronous pressure mechanism effectively avoids the uneven pressure problems that may occur with traditional point-by-point tightening, ensuring low and stable contact resistance at all electrical connection points, thereby improving conductivity, reducing the risk of overheating, and enhancing long-term reliability.

[0032] 3. Compact structure and highly integrated functions: This connector integrates multiple functions such as branch conduction, main line locking, and port sealing into one compact structure. Compared with solutions using multiple independent connectors, it significantly reduces the overall size and number of components, saves installation space, makes wiring neater, and reduces the potential failure rate caused by too many connection points.

[0033] 4. Excellent protective and mechanical properties: The dustproof sleeve design effectively seals the secondary cable hole, achieving dust and moisture protection and protecting the internal electrical connections. Simultaneously, the locking sleeve and bevel work together to securely clamp the main cable while effectively mitigating external pulling forces on the cable, improving the overall mechanical stability and vibration resistance of the connector.

[0034] In summary, this invention, with its integrated structural design and ingenious working principle, has achieved substantial progress in terms of ease of operation, connection reliability, structural compactness, and environmental adaptability, providing a high-performance, highly reliable one-to-many cable connection solution.

[0035] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0046] This invention provides a cable connector.

[0047] In this embodiment, refer to Figure 1-7 The cable connector includes:

[0048] The main body shell 1 has a main wire hole 2 for cables to pass through and a plurality of secondary wire holes 3 arranged around the main wire hole 2. A cavity 4 is formed inside the main body shell that communicates with the main wire hole and all the secondary wire holes.

[0049] The conductive piece 5 is fixedly disposed on the bottom wall of the cavity 5;

[0050] A clamping ring 6 is disposed in the cavity 5 and located above the conductive piece, and the clamping ring is connected to a linkage part 7 extending to the outside of the main body shell;

[0051] The locking screw sleeve 8 is rotatably fitted onto one end of the main wire hole of the main body shell. The locking screw sleeve has a threaded part 32 that is threaded to the main body shell, a connecting part 33 that is connected to the linkage part, and an insertion hole 9 through which the cable can pass.

[0052] Locking sleeve 10, the locking sleeve 10 is disposed inside the locking screw sleeve, and the outer wall of the locking sleeve and the inner wall of the insertion hole are provided with a mutually cooperating inclined structure 11;

[0053] When the locking sleeve is rotated to screw into the main body shell, the connecting part drives the clamping ring to move towards the conductive plate through the linkage part, so as to clamp and fix the cable passing through the secondary wire hole. At the same time, the inclined structure cooperates to cause the locking sleeve to shrink radially, so as to clamp and fix the main cable passing through the main wire hole.

[0054] In the above technical solution, the main body shell provides an overall installation carrier. The main cable hole allows the main cable to pass through, and the secondary cable hole allows multiple secondary cables to pass through in a loop. The cavity enables internal communication between the main and secondary cables. The conductive plate acts as a conductive medium, building an electrical connection bridge between the main and secondary cables. The clamping ring and the linkage are linked, and the locking sleeve, through its threaded part, engages with the main body shell to achieve axial movement. Its connecting part drives the linkage to drive the clamping ring. Simultaneously, the inclined structure of the inner and outer walls of the locking sleeve generates radial extrusion force when the locking sleeve is screwed in, forcing the locking sleeve to contract. Through the rotation operation of a single locking sleeve, the two actions of "secondary cable clamping and conduction" and "main cable locking and fixing" are simultaneously achieved, simplifying the operation process through mechanical linkage.

[0055] This achieves integrated one-to-many cable connections, solving the problems of existing "one-to-one" connectors requiring combined use and having a loose structure. It boasts high integration, reduces the number of components and connection nodes, and lowers the risk of failure. A single rotation operation simultaneously completes two core actions, eliminating the need to operate each secondary cable individually, significantly improving installation efficiency. The fixing and conduction of the main and secondary cables are achieved synchronously, ensuring the continuity and stability of the connection and avoiding connection deviations caused by step-by-step operations. The locking sleeve, in conjunction with the beveled structure, provides uniform clamping force on the main cable, preventing loosening and improving the mechanical stability of the connector.

[0056] It overturns the traditional multi-line connection model that requires multiple and multi-step operations. Only one tightening of the locking sleeving is needed to simultaneously complete the electrical connection and mechanical fixation of all cables, which can improve wiring efficiency several times.

[0057] In addition, multiple functions such as "one-to-many" electrical connection, main line tensile strength, and port guidance and positioning are integrated in a compact connector housing, reducing the number of components and installation space.

[0058] The main outer shell is typically injection molded from insulating engineering plastics (such as PA66 or PC), forming an integrated structure containing one main cable hole and multiple (e.g., 2, 3, or 4) radial secondary cable holes. The conductive plates are made of copper and are riveted or injection molded to the bottom wall of the cavity. The clamping ring is an insulating ring with multiple extending linkage plates connected to its upper surface. The locking nut is made of metal or high-strength plastic, with a tapered surface designed as a clamping ramp in its inner hole. The locking sleeve is an elastic tapered sleeve (such as brass or phosphor bronze) with multiple axial V-shaped notches, and its outer wall is a tapered surface that matches the clamping ramp. When the locking nut is tightened, its lower connecting part (as below) drives the linkage plates and clamping ring downwards; simultaneously, the clamping ramp squeezes the tapered surface of the locking sleeve, forcing it to radially contract and grip the main cable.

[0059] Specifically, the conductive piece is provided with a first protruding ring 12 and a second protruding ring 13 that surround the main wire hole and are spaced apart. The wire core 15 of the cable 14 that passes through the secondary wire hole is pressed between the pressing ring and the first protruding ring 12 and the second protruding ring 13.

[0060] A concave arc surface 16 is provided on the clamping ring at the secondary hole.

[0061] In this embodiment, the first and second convex rings form a raised annular "slot" structure around the main wire hole at the bottom of the cavity. The wire core of the secondary cable is guided into this "slot" (i.e., the area formed between the first and second convex rings). When the clamping ring is pressed down, its lower surface (preferably with an arc concave surface matching the curvature of the wire core) firmly presses the wire core into the enclosed space formed between the first and second convex rings, i.e., the clamping ring is located between the first and second convex rings. The double convex ring structure effectively enhances the mechanical holding force. In addition to the vertical clamping force, the sides of the convex rings also provide lateral constraints on the wire core, forming three-point or multi-point clamping, which greatly enhances the tensile and vibration resistance of the wire core, prevents loosening of the connection due to external forces, and improves the connection stability.

[0062] Specifically, the linkage part consists of multiple linkage plates spaced apart, which pass through the pressure groove 17 on the side wall of the main body shell; the connecting part consists of a first annular groove on the locking screw sleeve, with the end of the linkage plate extending into the first annular groove and axially limited by the anti-detachment structure 18 that limits mutual positioning, and the linkage plate and the first annular groove can rotate relative to each other.

[0063] In this embodiment, the linkage part consists of multiple spaced linkage plates that pass through the pressure groove of the main body shell and connect to the first annular groove to achieve linkage between the clamping ring and the outside. The connecting part adopts the first annular groove on the locking sleeving, and the end of the linkage plate extends into the annular groove. The anti-detachment structure achieves axial limiting (preventing the linkage plate from detaching from the annular groove). At the same time, the linkage plate and the annular groove can rotate relative to each other to ensure that when the locking sleeving rotates, it only drives the linkage plate to move axially and does not drive it to rotate synchronously, thus avoiding friction and jamming between the linkage plate and the main body shell.

[0064] Specifically, the main body shell includes an integral column 19 and a disc 20. The column 19 is provided with the main wire hole, and the outer wall of the column is provided with an external thread 21 that is threaded to the threaded part. The locking screw sleeve is provided with a second annular groove 22, and the threaded part is provided in the second annular groove. The cavity is formed in the disc body, and the secondary wire holes are spaced apart on the outer peripheral sidewall of the disc body.

[0065] In this embodiment, the main body shell adopts an integrated structure of column and disc. The column serves as the main cable connection end, with a main cable hole and external thread, which mates with the threaded part of the locking nut. The disc serves as the secondary cable connection end, with an internal cavity and a secondary cable hole on the outer periphery, realizing the spatial separation and communication between the main cable and the secondary cable. The locking nut is provided with a second annular groove, and the threaded part is placed in the groove, realizing the compact assembly of the locking nut and the locking nut.

[0066] Specifically, it also includes a dustproof rubber sleeve 23, which is fitted onto the disk body and has rubber holes 24 that correspond one-to-one with each secondary wire hole. The rubber holes 24 are provided with a sealing film 25 that can be passed through the cable.

[0067] In this embodiment, a dustproof sleeve is fitted onto the disk body, with its adhesive holes corresponding one-to-one with the secondary cable holes, allowing the secondary cables to pass through. A sealing film is provided inside the adhesive holes. When no cable is inserted, the sealing film closes the adhesive holes. When a cable is inserted, the film is punctured by the cable and tightly adheres to the outer wall of the cable, achieving a seal.

[0068] Specifically, the inner wall of the locking sleeve is provided with annular ridges 26 for increasing friction, and the side wall of the locking sleeve is provided with notches 27 spaced apart to facilitate radial contraction.

[0069] In this embodiment, the inner wall of the locking sleeve is provided with annular ridges to increase the friction between the locking sleeve and the outer wall of the main cable; the side wall of the locking sleeve is provided with notches at intervals so that the locking sleeve has radially retractable elasticity, and under the extrusion force of the inclined structure, it can quickly and evenly shrink and tightly fit the main cable.

[0070] Specifically, both the main wire hole and the secondary wire hole are provided with stepped rings 28, which are used to abut against the end of the insulating sleeve of the inserted cable.

[0071] In this embodiment, stepped rings are provided in both holes. When the cable is inserted, the end of the cable's insulating sleeve abuts against the stepped ring, thereby limiting the axial movement of the cable and preventing the cable from being inserted too deeply into the cavity, which would cause the wire core to become entangled. At the same time, it ensures that the exposed length of the wire core meets the conductivity requirements.

[0072] Specifically, the locking sleeve has a threaded connection section 29 at its end, and an operating section 31 is provided below the threaded connection section. The outer circumferential cross-section of the operating section is polygonal.

[0073] In this embodiment, a threaded connection section is provided at the end of the locking nut, which can be used to connect external cable connectors or equipment interfaces, expanding the applicable scenarios of the connector; an operating section is provided below the threaded connection section, and the outer circumferential cross section of the operating section is polygonal (such as hexagonal), which facilitates clamping with tools such as wrenches, so as to realize the fast and labor-saving rotation of the locking nut.

[0074] Specifically, the shape of the disc is circular or equilateral polygon.

[0075] In this embodiment, the disc body can be circular or equilateral polygonal. Circular disc bodies are easy to process and assemble, and the force is evenly distributed; equilateral polygonal disc bodies (such as regular hexagons and regular octagons) are easy to clamp and fix, and prevent the joint from rotating during use.

[0076] This application also provides a wiring method for a cable connector, comprising the following steps:

[0077] S1. Peel off the insulation sleeve of the main cable to expose the wire core, and insert the main cable through the insertion hole of the locking screw sleeve and the main wire hole of the main body shell until the end of its insulation sleeve is limited by the stepped ring and its wire core contacts the conductive piece.

[0078] S2. Peel off the insulation sleeve of at least one secondary cable to expose the wire core, and insert each secondary cable into the corresponding secondary cable hole until the end of its insulation sleeve is limited by the stepped ring and its wire core extends into the cavity inside the second convex ring.

[0079] S3. Rotate the locking sleeve so that it screws in relative to the main body shell;

[0080] S4. During the screwing process, the locking screw sleeve drives the clamping ring to move downward through the linkage part, pressing the core of each secondary cable between the clamping ring and the bottom wall of the cavity, thereby achieving electrical connection with the conductive piece; at the same time, the inclined structure inside the locking screw sleeve forces the locking sleeve to contract radially, pressing and fixing the main cable.

[0081] In this embodiment, during construction, the operator first uses wire strippers to uniformly strip a section of insulation (e.g., 10mm) from the ends of the main cable and all secondary cables according to the cable specifications. Then, following the sequence S1 and S2, all cables are threaded into the corresponding holes of the connector until the end of the insulation sleeve feels against the stepped ring. At this point, all wire cores are in the correct pre-connection position. Finally, a wrench is used to tighten the locking nut by turning it clockwise. The operator can feel the torque increasing smoothly until it is fully tightened. The entire process requires no other tools and no individual processing of each secondary cable.

[0082] Please note to all technical personnel: Although the present invention has been described according to the specific embodiments above, the ideas of the present invention are not limited to this invention. Any modifications that utilize the ideas of the present invention will be included within the scope of protection of this patent.
