DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1 , Figure 3-Figure 6 As shown, a reliable cable connector provided by an embodiment of the present invention includes a connector body 2, both ends of the connector body 2 are provided with cable holes for inserting cables A1 and B6, and also includes:

[0030] A plug-in fixing assembly, one plug-in fixing assembly is installed at each end of the connector body 2, the two plug-in fixing assemblies are arranged opposite to each other, and the two plug-in fixing assemblies are used to elastically fix the cable A1 and the cable B6 inserted into the connector body 2, respectively, and make the ends of the cable A1 and the cable B6 close to each other abut reliably;

[0031] A fixing component is also installed in the middle of the connector body 2 for fixing the connection area of ​​the cable A1 and the cable B6. The fixing component includes a fixing swivel 8, an inner annular shell 13, a fixing block 14 and a push-pull rod 27. An inner annular shell 13 is fixed to the middle of the inner side of the connector body 2. A plurality of fixing blocks 14 are circumferentially distributed and slidably arranged on the inner annular shell 13. A push-pull rod 27 is hinged at one end away from the plurality of fixing blocks 14. The other end of the push-pull rod 27 is hingedly connected to the fixing swivel 8 rotatably installed in the middle of the connector body 2. When the fixing swivel 8 is rotated, the fixing block 14 is driven to move by the push-pull rod 27, so that the connection area of ​​the cable A1 and the cable B6 is fixed or released at the same time by the plurality of fixing blocks 14.

[0032] In the embodiment of the present invention, when in use, the retaining swivel 8 is rotated to separate the multiple retaining blocks 14, and then the cable A1 and the cable B6 are inserted into the interior of the connector body 2 and pre-jointed (that is, the ends of the cable A1 and the cable B6 that are close to each other are preliminarily joined), and then the plug-in fixing component is operated to elastically fix the cable A1 and the cable B6 inserted in the connector body 2, and the ends of the cable A1 and the cable B6 that are close to each other are reliably joined, thereby ensuring the reliability of the electrical connection between the cable A1 and the cable B6; then, the retaining swivel 8 is rotated, and the retaining block 14 is driven to move by the push-pull rod 27, so that the connection area of ​​the cable A1 and the cable B6 is fixed at the same time by the multiple retaining blocks 14, so as to realize the reliable connection of the cable A1 and the cable B6, that is, the combination of the plug-in fixing component and the retaining component is used to realize the reliable installation and reliable electrical connection of the cable A1 and the cable B6, with a simple and reasonable structure and convenient application.

[0033] In summary, the present invention achieves high reliability and convenience of cable connection through the design of the plug-in fixing component and the fixing component, while ensuring the stability of the electrical connection.

[0034] like Figure 1-Figure 3 , Figure 5-Figure 6 As shown, as a preferred embodiment of the present invention, the inner end of the fixing block 14 is a middle arc-shaped concave structure, which can better match the cable A1 and the cable B6 and improve the reliability of fixation.

[0035] The middle part of the connector body 2 is circumferentially provided with a plurality of movable openings B26 for the push-pull rod 27 to pass through and swing, and the inner side of the fixing swivel 8 is circumferentially provided with a plurality of swinging cavities 25 for the push-pull rod 27 to swing, and the swinging cavities 25 are connected to the movable openings B26; the inner end of the push-pull rod 27 is hingedly connected to the fixing block 14 through a hinge support 29, and the outer end of the push-pull rod 27 is fixed with a support shaft B28, and the support shaft B28 is rotatably connected to the cavity wall of the swinging cavity 25.

[0036] Preferably, the inner end of the reinforcing block 14 is also provided with a conductive layer (not shown), and the area corresponding to the wire core between the cable A1 and the cable B6 is the connection area between the cable A1 and the cable B6. The conductive layer of the reinforcing block 14 is utilized to further ensure the reliability of the electrical connection between the cable A1 and the cable B6.

[0037] Preferably, a ratchet gear 7 is also fixed to one side of the retaining swivel 8 on the connector body 2, and a guide sleeve 11 is fixed to the side of the retaining swivel 8 close to the ratchet gear 7. A pull rod 9 is slidably provided on the guide sleeve 11, and the pull rod 9 is a T-shaped structure. A spring 10 is sleeved on the pull rod 9 on the upper side of the guide sleeve 11, and a butt 12 cooperating with the ratchet gear 7 is fixed to the lower end of the pull rod 9. There is no limitation on the structure of the butt 12, and a conventional arrangement can be sufficient; when there is no external force, under the elastic force of the spring 10, the butt 12 abuts against the teeth of the ratchet gear 7. By limiting the features of this part, the locking swivel 8 can only rotate in one direction, so that the locking block 14 remains stable after abutting against the cable A1 and the cable B6, thereby achieving the purpose of one-way rotation locking; if it is necessary to release the cable A1 and the cable B6, it is only necessary to pull the pull rod 9 to separate the abutting head 12 from the ratchet gear 7, and the locking swivel 8 can be rotated in the opposite direction to the initial position, which is convenient and quick, ensuring the reliability of the connection and the convenience of operation.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the plug-in fixing assembly includes a crimping push ring 3, an L-shaped support 16, an arc-shaped elastic telescopic rod 17, an L-shaped crimping rod 18, a fulcrum A19, an ear plate 20, an elastic telescopic inner rod 21 and a crimping column 23. The inner end of the connector body 2 is circumferentially distributed with a plurality of L-shaped crimping rods 18, a fulcrum A19 is fixed at the corner of the L-shaped crimping rod 18, the fulcrum A19 is rotatably connected to the ear plate 20, the ear plate 20 is fixedly connected to the inner wall of the connector body 2, the inner end of the L-shaped crimping rod 18 is fixed with a crimping column 23, the outer end of the L-shaped crimping rod 18 is installed with an elastic telescopic inner rod 21, and the elastic telescopic inner rod 21 extends into the crimping push ring 3. The crimping push ring 3 is rotatably mounted on the outer end of the connector body 2 in the linkage groove 15. The outer end side of the L-shaped crimping rod 18 is also fixed with an arc-shaped elastic telescopic rod 17. The other end of the arc-shaped elastic telescopic rod 17 is fixed with an L-shaped support 16. The L-shaped support 16 is also fixedly connected to the inner wall of the connector body 2. When there is no external force, under the elastic force of the arc-shaped elastic telescopic rod 17, multiple crimping columns 23 gather toward the middle of the connector body 2; when the crimping push ring 3 is pushed to move toward the middle of the connector body 2, under the limiting action of the linkage groove 15, the L-shaped crimping rod 18 overcomes the elastic force of the arc-shaped elastic telescopic rod 17 and rotates, and multiple crimping columns 23 are dispersed. In addition, the purpose of arranging the elastic telescopic inner rod 21 is to adapt to the swing of the L-shaped crimping rod 18 and the horizontal movement of the crimping push ring 3 through its telescopic adaptation, so that the elastic telescopic inner rod 21 always extends into the linkage groove 15, and the linkage groove 15 can reliably toggle it.

[0039] Preferably, a plurality of guide edges 4 are circumferentially distributed and fixed on the connector body 2, and the crimping push ring 3 is slidably connected to the guide edges 4, thereby ensuring the sliding reliability of the crimping push ring 3 and preventing the crimping push ring 3 from being twisted.

[0040] Preferably, the connector body 2 is circumferentially provided with a plurality of movable openings A22 for the L-shaped crimping rod 18 to pass through and swing, and the movable opening A22 is also connected to the linkage groove 15; the arc-shaped elastic telescopic rod 17 adopts an arc-shaped structure, and the center of the arc-shaped elastic telescopic rod 17 is located on the axis of the support shaft A19, so that the arc-shaped elastic telescopic rod 17 can reliably support the L-shaped crimping rod 18.

[0041] Preferably, the crimping column 23 is an arc-shaped concave structure in the middle, which improves the reliability of the limiting fixation of the cable A1 and the cable B6. The surface of the crimping column 23 is also circumferentially distributed with a plurality of anti-slip edges 24 to prevent the cable A1 and the cable B6 from slipping and improve the reliability of the abutment fixation.

[0042] like Figure 1 As shown, as a preferred embodiment of the present invention, sealing sheets 5 for sealing the inserted cables A1 and B6 are circumferentially installed on the cable holes at both ends of the connector body 2. The sealing sheets 5 are made of elastic material and are fan-shaped, which ensures that the sealing sheets 5 are tightly abutted against the cables A1 and B6, thereby making the entire connector more reliable.

[0043] The above embodiment of the present invention provides a cable connector with reliable connection, and the specific working process is as follows:

[0044] 1) First, rotate the locking ring 8 to separate the locking block 14 to facilitate the insertion of the cable A1 and the cable B6. Insert the cable A1 and the cable B6 from both ends of the connector body 2 respectively until the connection ends of the two cables are in contact or close to each other, forming a preliminary docking.

[0045] 2) Push the crimping push ring 3 to move toward the center of the connector body 2. Through the action of the linkage groove 15, the L-shaped crimping rod 18 overcomes the elastic force of the arc-shaped elastic telescopic rod 17 and opens outward, so that the crimping column 23 moves toward the center of the connector body 2, exerting pressure on the ends of the cables A1 and B6 to achieve preliminary elastic fixation. The arc-shaped concave design in the middle of the crimping column 23 and the anti-slip ridge 24 on the surface help to enhance the clamping force on the cable and prevent the cable from slipping.

[0046] 3) After ensuring that the cable A1 and the cable B6 have been properly connected, rotate the fixing swivel 8 in the opposite direction, and drive the fixing block 14 to move to the connection area of ​​the cable A1 and the cable B6 through the push-pull rod 27 to achieve a more secure fixation. The inner end of the fixing block 14 is also designed as a middle arc-shaped concave structure to better adapt to the shape of the cable and improve the stability of the fixation. In addition, the conductive layer on the fixing block 14 can increase the reliability of the electrical connection between the cables.

[0047] 4) The one-way locking mechanism composed of the ratchet gear 7, the pull rod 9, the spring 10 and the butt 12 on one side of the fixing swivel 8 ensures that the fixing swivel 8 can only rotate in one direction, thereby preventing the fixed cable from accidentally loosening. To release the fixation, just pull the pull rod 9 to disengage the butt 12 from the ratchet gear 7, and then rotate the fixing swivel 8 in the opposite direction to release the cable.

[0048] 5) The sealing sheets 5 installed on the cable holes at both ends of the connector body 2 can effectively prevent moisture, dust, etc. in the external environment from entering the connector, protect the cable connection parts from damage, and maintain good electrical performance.

[0049] In summary, the cable connector with reliable connection realizes fast and reliable connection of cables through the ingenious combination of the plug-in fixing component and the fixing component.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
