Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, and in particular to a cable connector for electric power construction. Background Art

[0002] A power cable connector refers to a structure used to connect two cables to each other, and is generally used for connection operations when power cables are laid or when power cables are broken.

[0003] The existing cable connection method is generally to connect the ends of two cable segments manually when laying the cable. Specifically, there are multiple wires on the two existing cables, and the corresponding two wires are connected one by one. The conventional operation method of the workers is as follows Figure 1 As shown, after the cables at both ends are stripped, a corresponding set of wires are crossed in an X shape, twisted and spun together, and the end of one wire is wrapped around the body of another wire for several turns, and finally the connection is fixed by wrapping an insulating tape, and then each set of wires is installed in sequence and connected one by one according to the above operations to achieve the connection of the two cables.

[0004] The above connection process has the following problems: (1) The connection efficiency is low. Workers need to perform repetitive operations many times to connect multiple groups of wires in sequence. Each time the two wires are twisted, it is necessary to confirm whether they match, which wastes labor.

[0005] (2) Poor protection. For example, in the process of overhead or underground cable installation, the method of twisting and winding and then wrapping with super insulating tape is adopted. The overall protection can only be achieved by mutual isolation through the insulating tape. When under pressure or wind, it is easy to cause detachment or mutual contact, resulting in a short circuit. Summary of the invention

[0006] The object of the present invention is to provide a cable connector for electric power construction, so as to solve the problems in the prior art of low cable connection efficiency, inability to quickly twist, and low protection.

[0007] In order to solve the above problems, the cable connector for power construction involved in the present invention adopts the following technical solutions: A cable connector for electric power construction, comprising a protective shell, a twisting mechanism for mutually crossing and relatively twisting the same group of wires to be twisted at the ends of two cables, and a driving mechanism for driving the twisting mechanism to move is also provided in the protective shell; The twisting mechanism comprises an insulating twisting seat fixed in a protective shell, a guide hole is arranged through the insulating twisting seat, two twisting rods are inserted in the guide hole, the two twisting rods are arranged symmetrically in back to back, a twisting hole is opened on the twisting rod, the twisting hole comprises a straight hole section, a receiving hole section connected to the tail end of the straight hole section, and a cross-guide hole section connected to the tail ends of the two receiving hole sections, the diameter of the receiving hole section is not less than twice the diameter of the straight hole section, and the cross-guide hole section is used to guide one of the wires extending horizontally from one end of the twisting hole to enter the receiving hole section of another twisting rod after being inclined, so as to be arranged in an X-shaped cross with the other wire; The two twisted rods are arranged relatively close to each other in the initial state, and the cross-guide hole sections on the two twisted rods extend and transition relatively smoothly; The driving mechanism includes a rotating and approaching mechanism connected to the insulating twisted seat for driving the two twisted rods to rotate synchronously in opposite directions so as to drive the two insulating twisted seats to move away from each other and closer to each other. When the rotating and approaching mechanism drives the two twisted rods to rotate away from each other, the two cross-arranged wires in the twisted rods are relatively entangled to achieve twisting. The driving mechanism also includes a driving component that cooperates with the rotating and approaching mechanism in transmission.

[0008] Furthermore, there are a plurality of guide holes, which are arranged side by side at intervals on the insulating twisted seat, and the axes of the guide holes are arranged in parallel.

[0009] Furthermore, the cross-guide hole section includes two guide hole structures arranged side by side along the radial direction of the twisted hole, one of which is for horizontal insertion of the wire, and the other is for oblique passage of the wire, and the inner ends of the two guide hole structures of one twisted rod are defined as a first entrance and a first exit, respectively, and the inner ends of the two guide hole structures of the other twisted rod are defined as a second entrance and a second exit, respectively, the first entrance is connected to the second exit, the second entrance is connected to the first exit, and the first entrance and the second entrance are coaxially arranged so that the two guides are relatively coaxially inserted and extend in an X-shaped cross.

[0010] Furthermore, the twisted rod includes a smooth rod section that is inserted into the guide hole and a screw section that is connected to the smooth rod section, the screw section has an external thread, and the side walls of the insulating twisted seat are provided with accommodating grooves near the two end positions, and the two accommodating grooves are both connected to the guide hole. The rotational disengagement mechanism includes two driving gears that are respectively rotatably assembled in the two accommodating grooves, the driving gears are coaxially arranged with the guide hole, and the inner surfaces of the driving gears are arranged with internal threads. The two driving gears are respectively threadedly assembled with the screw sections of the two twisted rods, and the rotation directions of the two are opposite; the rotational disengagement mechanism also includes an external tooth structure that meshes with the driving gears for transmission, and the driving component cooperates with the external tooth structure to drive the driving gear to rotate, thereby driving the twisted rod to rotate and move in the guide hole.

[0011] Furthermore, the outer tooth structure includes two inner tooth rings coaxially sleeved on the outer side of the insulating twisted seat, and the two inner tooth rings are respectively meshed with two driving gears for transmission.

[0012] Furthermore, the inner ends of the two inner gear rings are coaxially fixedly connected with drive rings, a rotating bearing is clamped between the drive ring and the protective shell, and the drive component is connected to the two drive rings.

[0013] Furthermore, the driving component includes a driving plate integrally mounted between the two driving rings, and the driving plate is provided with a tool connector for inserting a tool sleeve to drive the inner gear ring to rotate synchronously.

[0014] Furthermore, the tool connector includes a connecting rod connected to the center of the driving plate, the connecting rod extends outward along the radial direction of the insulating twisted seat and through the protective shell, and the end of the connecting rod has a hexagonal hole.

[0015] Furthermore, the insulating twisted seat includes two symmetrically arranged connecting seats, and also includes a fixed hoop and a movable hoop which are sleeved on the outside of the two connecting seats. One end of the connecting seat is provided with an outward turning edge, and the fixed hoop has a limiting groove for accommodating the two outward turning edges to arrange the two connecting seats coaxially. The fixed hoop and the movable hoop are mutually sleeved and arranged.

[0016] Furthermore, the protective shell includes a bottom shell and a top shell sleeved on the bottom shell, the bottom shell is provided with an external connection hole, and the top shell is provided with a long avoidance groove for avoiding the input end of the driving component.

[0017] The beneficial effects of the present invention are as follows: when the cable connector is actually used, the end wires of the two cables to be connected are aligned with the corresponding twisting holes and inserted, and the two cables are driven toward each other by external force (such as manual pulling or double-headed screw drive), and are respectively inserted into the corresponding twisted rods, and obliquely inserted into the receiving hole section of the other twisted rod through the cross guide hole section of the twisted rod. Only one insertion can achieve a single wire or even multiple wires once, without the need for subsequent repeated identification, and at the same time achieve an X-shaped oblique crossing of the two wires.

[0018] The two twisted rods are driven by the rotating separation mechanism to rotate away from each other, so that the ends of the two X-shaped cross-arranged wires are synchronously wound relative to each other, achieving the effect of the prior art. Figure 1 The twisted connection structure shown in the figure makes the cable connection tighter. The horizontal twisted arrangement of two wires can be achieved by one-time guided insertion and one-time rotation drive, which can make the twisted connection process of the wires more convenient and quick, and effectively improve the connection efficiency of the cable.

[0019] At the same time, the connector can directly and effectively insulate the outside of the wires after the wires are twisted. Due to the high twisting density, the connection is highly stable and safe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the technical purpose, technical solution and beneficial effects of the present invention clearer, the technical solution of the present invention is further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0022] The specific embodiment of the cable connector for power construction involved in the present invention is as follows: Figures 2 to 10 As shown, the cable connector for power construction includes a protective shell 1, a twisting mechanism, and a driving mechanism. The twisting mechanism and the driving mechanism are both installed in the protective shell 1, wherein the twisting mechanism is used to cross and twist the same group of wires to be twisted at the ends of two cables with each other, and the driving mechanism is used to connect the twisting mechanism to drive the twisting mechanism to move.

[0023] The twisting mechanism includes an insulating twisting seat 2 fixed in the protective shell 1. In this embodiment, the insulating twisting seat 2 is a cylindrical structure as a whole. At the same time, the insulating twisting seat 2 includes two symmetrically arranged connecting seats 21, and also includes a fixed hoop 22 and a movable hoop 23 sleeved on the outside of the two connecting seats 21. One end of the connecting seat 21 is provided with an outward edge, and the fixed hoop 22 has a limiting groove 222 for accommodating two outward edges to arrange the two connecting seats 21 coaxially. The fixed hoop 22 and the movable hoop 23 are mutually encircled and arranged. The two connecting seats 21 are used in a pair, which can facilitate machining and facilitate the subsequent assembly of parts. The fixed hoop 22 and the movable hoop 23 are mainly used to keep the two connecting seats 21 coaxially limited to avoid radial and axial movement. In the actual assembly process, the connecting seat 21 and the fixed hoop 22 can be connected by screws, welding, clamping, etc. to achieve circumferential anti-rotation assembly. The bottom of the fixed hoop 22 is connected with a connecting plate, and the connecting plate is provided with a mounting hole 221.

[0024] The corresponding protective shell 1 is a cylindrical structure, which includes a bottom shell 11 that is radially opposite to each other and a top shell 12 that is sleeved on the bottom shell 11. The bottom shell 11 has an external connection hole 111, and the top shell 12 has an avoidance long groove 121, which extends along the circumferential direction of the protective shell 1. The above-mentioned fixing hoop 22 is fixed inside the bottom shell 11 through the mounting hole 221 thereon, and is coaxially arranged with the protective shell 1.

[0025] During the actual assembly process, the bottom shell 11 is fixedly connected to the corresponding installation position, the fixing hoop 22 is fixed in the bottom shell 11, and then the two connecting seats 21 of the insulating twisted seat 2 are respectively fixed in the limiting grooves 222 of the fixing hoop 22, so that the coaxial installation of the insulating twisted seat 2 in the protective shell 1 can be realized.

[0026] The insulating twisting seat 2 is provided with a guide hole 211 through which a group of wires (two wires to be twisted) are inserted. The two wires are inserted from both ends of the guide hole 211. Of course, for a cable with multiple wires at the end, in order to achieve a fast synchronous twist connection, in this embodiment, Figure 2 As shown, there are multiple guide holes 211, each guide hole 211 is evenly spaced around the circumference of the insulating twisting seat 2, and the axes of each guide hole 211 are arranged in parallel. At the same time, each guide hole 211 can provide a group of wire twisting connection operations. In this way, the twisting operation of all wires can be achieved through one matching, one threading, and one twisting operation, which is simple to operate and has high cable connection efficiency.

[0027] Of course, in other preferred embodiments, only one guide hole 211 may be provided, or more guide holes 211 may be provided, and the design is based on the actual number of conductors of the cable, and is not specifically limited.

[0028] Two twisted rods 3 are inserted and guided in the guide hole 211. The two twisted rods 3 are symmetrically arranged back to back. A twisted hole 31 is opened on the twisted rod 3. The twisted hole 31 includes a straight hole section 311, a receiving hole section 312 connected to the tail end of the straight hole section 311, and a cross-guide hole section 313 connected to the tail ends of the two receiving hole sections 312. The diameter of the receiving hole section 312 is not less than twice the diameter of the straight hole section 311. The cross-guide hole section 313 is used to guide one of the wires horizontally extending from one end of the twisted hole 31 to enter the receiving hole section 312 of the other twisted rod 3 after being obliquely guided, so as to be arranged in an X-shape with the other wire.

[0029] In actual operation, the wire is inserted from the guide hole 211 into the twisting hole 31, passes through the straight hole section 311 and enters the receiving hole section 312, and then enters the inclined guidance of the cross guide hole section 313, and then extends into the cross guide section of another twisting hole 31, and then extends into the receiving hole section 312. At this time, another wire is inserted in the opposite direction, and the two form an X-shaped cross arrangement, which is convenient for subsequent twisting operations. In order to ensure that the two wires can pass smoothly through the cross guide hole sections 313 of the two twisting rods 3, the two twisting rods 3 are relatively close-fittingly arranged in the initial state, and the cross guide hole sections 313 on the two twisting rods 3 extend and transition relatively smoothly.

[0030] Preferably, in order to achieve cross-oblique guiding of two conductors and realize X-shaped arrangement of the conductors, the cross-guiding hole section 313 includes two sections of guide hole 211 structures arranged side by side along the radial direction of the twisting hole 31, one of the guide hole 211 structures is for horizontal insertion of the conductor, and the other guide hole 211 structure is for oblique passage of the conductor, and the inner ends of the two guide hole 211 structures of one twisted rod 3 are defined as the first entrance 34 and the first exit 35, respectively, and the inner ends of the two guide hole 211 structures of the other twisted rod 3 are respectively the second entrance 36 and the second exit 37, the first entrance 34 is connected with the second exit 37, the second entrance 36 is connected with the first exit 35, and the first entrance 34 and the second entrance 36 are coaxially arranged so that the two guides are relatively coaxially inserted and extend out in an X-shaped cross.

[0031] During actual threading, taking one of the wires as an example, the wire is horizontally inserted into the twisted hole 31, then enters through the first entrance 34 and exits through the second exit 37. Since the first entrance 34 and the second entrance 36 are coaxially arranged, and the second exit 37 and the second entrance 36 are radially arranged, the wire can extend out in a direction on one side of the radial direction relative to the second entrance 36 after being guided by the inclined hole section between the first entrance 34 and the second exit 37, and vice versa for the other wire, thereby achieving an X-shaped cross extension.

[0032] After the threading is completed, the twisting rod 3 needs to be driven to drive the two X-shaped cross-arranged wires to be twisted relative to each other. At this time, the twisting rod 3 is driven to rotate and move by a driving mechanism.

[0033] Specifically, taking the movement process of the two twisted rods 3 in one of the guide holes 211 as an example, the driving mechanism includes a rotating and approaching mechanism 4 connected to the insulating twisted seat 2 for driving the two twisted rods 3 to rotate synchronously in opposite directions, so as to drive the two insulating twisted seats 2 to move away from each other and relatively close to each other. When the rotating and approaching mechanism 4 drives the two twisted rods 3 to rotate away from each other, the two cross-arranged wires in the twisted rod 3 are relatively entangled to achieve twisting.

[0034] Preferably, in order to realize the rotational separation process, the twisted rod 3 includes a smooth rod segment 32 which is guided and plugged into the guide hole 211 and a screw segment 33 which is connected to the smooth rod segment 32, the screw segment 33 has an external thread, and the side walls of the insulating twisted seat 2 are provided with accommodating grooves 212 near the two end positions, and the two accommodating grooves 212 are both connected to the guide hole 211, and the rotational separation mechanism 4 includes two driving gears 41 which are respectively rotatably assembled in the two accommodating grooves 212, the driving gear 41 is coaxially arranged with the guide hole 211, and the inner surface of the driving gear 41 is arranged with an internal thread 411, and the two driving gears 41 are respectively threadedly assembled with the screw segments 33 of the two twisted rods 3, and the rotation directions of the two are opposite; the rotational separation mechanism 4 also includes an external tooth structure which meshes with the driving gear 41 for transmission.

[0035] That is to say, the driving gear 41 can be driven to rotate through the meshing transmission of the external tooth structure and the driving gear 41. Due to the threaded assembly of the driving gear 41 and the twisted rod 3, when the driving gear 41 rotates, it can drive the twisted rod 3 to rotate and slide along the axial direction of the guide hole 211. During this rotation and sliding process, the two wires are relatively rotated and entangled at the ends of the twisted rod 3, and are twisted and connected in sequence during the movement, thereby realizing the twisting operation of the wires.

[0036] In order to realize the driving of the external tooth structure, the driving mechanism also includes a driving component 5 that cooperates with the rotating disengagement mechanism 4. The driving component 5 cooperates with the external tooth structure to drive the driving gear 41 to rotate, thereby driving the twisted rod 3 to rotate and move in the guide hole 211.

[0037] In order to achieve synchronous driving of the two driving gears 41, the external gear structure includes two inner gear rings 42 coaxially sleeved on the outside of the insulating twisting seat 2, and the two inner gear rings 42 are respectively meshed with the two driving gears 41 for transmission. Of course, the two inner gear rings 42 can also meet the driving process of multiple sets of wire twisting operations, such as Figure 3 As shown, a receiving groove 212 is arranged on the circumferential side of the insulating twisting seat 2 corresponding to each guide hole 211, and a driving gear 41 is arranged in each receiving groove 212, and the inner gear ring 42 is sleeved on the outside of each driving gear 41. By rotating one inner gear ring 42, all the driving gears 41 can be driven to rotate synchronously, thereby realizing the synchronous twisting operation of each group of wires.

[0038] In order to ensure the coaxiality between the two inner gear rings 42 and between the inner gear ring 42 and the insulating twisted seat 2, the inner ends of the two inner gear rings 42 are coaxially fixedly connected with a drive ring 43, a rotating bearing 44 is clamped between the drive ring 43 and the protective shell 1, and the drive component 5 is connected to the two drive rings 43.

[0039] In order to realize the rotational drive of the driving ring 43, the above-mentioned driving component 5 includes a driving plate 51 integrally mounted between the two driving rings 43, and a tool connector is provided on the driving plate 51 for inserting a tool sleeve to drive the inner gear ring 42 to rotate synchronously. Preferably, in order to realize the drive, the tool connector includes a connecting rod 52 connected to the center position of the driving plate 51, and the connecting rod 52 extends outward along the radial direction of the insulating twisting seat 2 and through the protective shell 1, and the end of the connecting rod 52 has a hexagonal hole. By inserting the external hexagonal handle head 53 into the hexagonal hole, and then toggling the handle head 53, the twisting operation of the twisting rod 3 can be driven. The connecting rod 52 passes through the avoidance long groove 121 of the above-mentioned protective shell 1, which is convenient for operation and has a certain degree of protection.

[0040] During actual assembly, the twisted rod 3 is sequentially inserted into the corresponding guide hole 211, and the two guide holes 211 are aligned, then the driving gear 41 is rotated onto the twisted rod 3, and then the two end receiving grooves 212 of the insulating twisted seat 2 are blocked and fixed by the sealing plate. After that, the inner gear ring 42 and the driving ring 43 are relatively fixedly connected and clamped on the bottom shell 11 of the protective shell 1 through the bearing 44, the insulating twisted seat 2 is inserted into the inner gear ring 42, and placed in the fixing hoop 22, the fixing hoop 22 is fixed on the bottom shell 11, and finally the movable hoop 23 is put on, the driving plate 51 is pressed, the connecting rod 52 is fixed, and finally the top shell 12 is covered on the bottom shell 11, and the assembly can be realized.

[0041] When in use, in the initial state, the two twisted rods 3 are attached to each other, and the cross-guide hole section 313 is smoothly transitioned. The end wires of the two cables to be connected in the same group are aligned with the corresponding twisted holes 31. After each group of wires is rotated, they are uniformly inserted into the corresponding twisted holes 31, and the two cables are driven towards each other through external force (such as manual pulling or double-headed screw drive), and are respectively inserted into the corresponding twisted rods 3, and obliquely inserted into the receiving hole section 312 of the other twisted rod 3 through the cross-guide hole section 313 of the twisted rod 3, forming an X-shaped cross arrangement. Then the worker inserts the outer handle head 53 into the connecting rod 52, and moves the handle head 53 to drive the connecting rod 52 to swing, and the connecting rod 52 drives the inner gear ring 42 to rotate, and then drives each driving gear 41 to rotate synchronously, so that the two twisted rods 3 are synchronously rotated away from the drive. In the process of rotating away, the two crossed wires are relatively twisted and twisted, and finally the wire twisting and cable connection operation is realized.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
