Description

Technical Field

[0001] The present application relates to the technical field of protective shells, and in particular to a wire protection shell for a connector. Background Art

[0002] A wire protection shell (also called a wire protection coil, wire protector, wire protection pad, wire guide) is an accessory used to protect wires, cables and other connecting wires, and is mainly used in the fields of electrical and communications. During the use of the connector, the wire protection shell can protect the connecting wire from being pulled, squeezed, rubbed and other damage when passing through the opening and turning, thereby avoiding the interruption or exposure of energy and signals.

[0003] In the related art, the wire protection shell used for the connector is usually made of plastic. An insert block is provided on the side of the connector body connected to the cable, and a fixing groove for inserting the insert block is provided on the inner wall of the wire protection shell body, that is, the wire protection shell body is fixed to the connector body by snap-fitting.

[0004] When removing the wire protection shell from the connector, it is usually necessary to use other tools (such as a screwdriver) to remove the plug from the slot to achieve the removal of the wire protection shell. The process is relatively cumbersome. In addition, some connectors are used in scenarios with relatively narrow spaces, and it is inconvenient to remove the wire protection shell with the help of tools, which will further affect the removal efficiency of the wire protection shell, and there is room for improvement. Utility Model Content

[0005] The purpose of the present application is to provide a wire protection shell for a connector, so as to solve the problem of low disassembly efficiency of the wire protection shell in the above-mentioned related art.

[0006] The present application provides a wire protection shell for a connector using the following technical solution:

[0007] A wire protection shell for a connector comprises a wire protection shell body, a cable access port is arranged on one side of the wire protection shell body, a clearance gap is arranged on the wire protection shell body for inserting a card block, and damping occurs during the insertion of the card block into the clearance gap; the clearance gap comprises a positioning groove arranged on the side edge of the wire protection shell body facing the connector body and a limiting groove arranged on the side wall of the positioning groove.

[0008] By adopting the above technical solution, during the assembly process of the wire protection shell body and the connector body, due to the setting of the clearance gap, the card block on the connector body is first inserted into the positioning groove, and then the wire protection shell body is slid to insert and fix the card block into the limiting card slot, thereby realizing a detachable connection between the wire protection shell body and the connector body. When the wire protection shell body is subsequently removed from the connector body, it can be quickly removed without the aid of other tools, thereby improving the disassembly efficiency of the wire protection shell body.

[0009] Optionally, the inner corner where the positioning through slot and the side wall of the limiting slot are connected is a guiding arc surface.

[0010] By adopting the above technical solution, when the card block is inserted from the positioning slot into the limiting slot, due to the setting of the guide arc surface, the card block can be inserted into the limiting slot along the guide arc surface, which facilitates the card block on the connector body to be inserted from the positioning slot into the limiting slot.

[0011] Optionally, a stopper is provided on the outer side of the wire protection shell body to prevent the card block from falling out of the limiting card slot in a natural state.

[0012] By adopting the above technical solution, when the wire protection shell main body is installed on the connector body, due to the setting of the stop block, the block cannot be retracted from the limit slot to the positioning slot in the natural state, thereby reducing the possibility of loosening of the assembly of the wire protection shell main body and the connector body in the natural state, thereby improving the assembly stability of the wire protection shell main body and the connector body.

[0013] Optionally, a guiding slope is provided on the side edge of the stopper facing the connector body.

[0014] By adopting the above technical solution, due to the setting of the guiding inclined surface, it is convenient for the stopper to limit the upper limit block of the connector body in the subsequent process, thereby improving the performance of the wire protection shell.

[0015] Optionally, an observation notch is provided on a side of the wire protection shell body away from the cable access port.

[0016] By adopting the above technical solution, due to the setting of the observation notch on the wire protection shell, it is possible to conveniently check whether the wires or connecting wires are normal, loose or damaged by observing the notch. In this way, problems can be discovered at the first time to avoid potential safety hazards; during installation or maintenance, the observation notch can provide a more intuitive visual guide, making it easier for the operator to put the wires or connecting wires into the wire protection shell, or replace and adjust them when necessary.

[0017] Optionally, a wiring notch is provided on the side of the wire protection shell body close to the cable inlet.

[0018] By adopting the above technical solution, due to the setting of the wiring gap, the cables on the connector are further given way, which facilitates the subsequent adjustment of the cable layout.

[0019] Optionally, the inner corner of the wiring gap is rounded.

[0020] By adopting the above technical solution, when the wire protection shell is subjected to impact or other external forces, the stress concentration can be reduced due to the rounded inner corner of the wiring notch, thereby enhancing the impact resistance of the wire protection shell when subjected to impact, and improving the durability and service life of the wire protection shell.

[0021] Optionally, a reinforced flange is provided on the outer side surface of the wire protection shell body close to the cable access port.

[0022] By adopting the above technical solution, the structural strength of the wire protection shell body close to the cable access port is improved, thereby increasing the service life of the wire protection shell.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Due to the setting of the clearance gap, when the wire protection shell body and the connector body are assembled, the card block on the connector body is first inserted into the positioning groove, and then the wire protection shell body is slid to insert and fix the card block into the limiting card groove, so as to realize the detachable connection between the wire protection shell body and the connector body. When the wire protection shell body is subsequently removed from the connector body, it can be quickly removed without the help of other tools, thereby improving the disassembly efficiency of the wire protection shell body.

[0025] 2. Due to the setting of the stopper, when the wire protection shell body is installed on the connector body, the block cannot be retracted from the limit slot to the positioning slot in the natural state, reducing the possibility of loosening of the assembly of the wire protection shell body and the connector body in the natural state, thereby improving the assembly stability of the wire protection shell body and the connector body.

[0026] 3. Due to the setting of the observation notch on the wire protection shell, it is convenient to check whether the wires or connecting wires are normal, loose or damaged by observing the notch. In this way, problems can be discovered at the first time to avoid potential safety hazards; during installation or maintenance, the observation notch can provide a more intuitive visual guide, making it easier for operators to put wires or connecting wires into the wire protection shell, or replace and adjust them when necessary.

DETAILED DESCRIPTION

[0037] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0038] Example:

[0039] Reference Figure 1 and Figure 2 A wire protection shell for a connector includes a wire protection shell body 1, which is made of plastic. The wire protection shell body 1 is provided with a clearance gap 11 for inserting and limiting a block 21 on a connector body 2. There is damping in the process of inserting the block 21 into the clearance gap 11. A cable access port 12 is provided on one side of the wire protection shell body 1, and the cables connected to the connector body 2 can be led out from the cable access port 12.

[0040] Refer to 3 and Figure 4The clearance gap 11 includes a positioning slot 111 disposed on the side edge of the wire protection shell body 1 facing the connector body 2 and a limiting card slot 112 disposed on the side wall of the positioning slot 111; when the wire protection shell body 1 and the connector body 2 are assembled, the card block 21 on the connector body 2 is first inserted into the positioning slot 111, and then the wire protection shell body 1 is slid to insert the card block 21 into the limiting card slot 112. The inner corner where the positioning slot 111 and the side wall of the limiting card slot 112 are connected is a guide arc surface 113, which is arranged to facilitate the card block 21 on the connector body 2 to be inserted from the positioning slot 111 into the limiting card slot 112.

[0041] Reference Figure 5 and Figure 6 The outer side surface of the wire protection shell body 1 is provided with a stopper 13 for preventing the card block 21 from escaping from the limiting card groove 112 in a natural state; at the same time, a limiting block 22 is fixedly arranged on the connector body 2; and a guiding inclined surface 131 is provided on the side edge of the block 13 facing the connector body 2, so that the block 13 is easily inserted into one side of the limiting block 22, thereby improving the performance of the wire protection shell.

[0042] When the wire protection shell body 1 is installed on the connector body 2, one side of the stop block 13 abuts against one side of the limit block 22, that is, the stop block 13 and the limit block 22 limit each other, so that the card block 21 cannot retreat from the limit card groove 112 to the positioning groove 111 in a natural state; when the wire protection shell body 1 needs to be removed from the connector body 2, the user needs to apply force to press the body to release the mutual limit between the limit block 22 and the stop block 13 to facilitate the next step of disassembly.

[0043] Reference Figure 7 A wiring notch 15 is provided on the side of the cable protection shell body 1 near the cable access port 12. Due to the provision of the wiring notch 15, the cables on the connector further give way, which facilitates the subsequent adjustment of the cable layout. The inner corner of the wiring notch 15 is rounded; the rounded corner design can reduce stress concentration and enhance the impact resistance of the cable protection shell when it is impacted, which helps to improve the durability and service life of the cable protection shell.

[0044] Reference Figure 7 A reinforcing flange 16 is fixedly provided on the outer surface of the wire protection shell body 1 near the cable outlet 12. The reinforcing flange 16 is also made of plastic material, and the reinforcing flange 16 is integrally injection molded with the wire protection shell body 1, so as to improve the structural strength of the wire protection shell body 1 near the cable outlet 12, thereby improving the service life of the wire protection shell.

[0045] Reference Figure 7 and Figure 8The side of the cable protection housing body 1 away from the cable access port 12 is provided with an observation notch 14; through the observation notch 14, it is convenient to check whether the wires or connecting wires are normal, loose or damaged. In this way, problems can be discovered at the first time to avoid potential safety hazards; during installation or maintenance, the observation notch 14 can provide a more intuitive visual guide, making it easier for the operator to put the wires or connecting wires into the cable protection housing, or replace and adjust them when necessary.

[0046] The implementation principle of the embodiment of the present application is:

[0047] When the wire protection shell body 1 is installed on the connector body 2, the block 21 on the connector body 2 is first inserted into the positioning slot 111, and then the wire protection shell body 1 is slid to insert the block 21 into the limiting slot 112; at this time, one side of the stopper 13 abuts against one side of the limiting block 22, that is, the stopper 13 and the limiting block 22 limit each other, so that the block 21 cannot retreat from the limiting slot 112 to the positioning slot 111 in a natural state;

[0048] When it is necessary to remove the wire protection shell body 1 from the connector body 2, the user needs to press the body to release the mutual limitation between the limit block 22 and the stop block 13, and then move the card block 21 from the limit card slot 112 to the positioning slot 111, and finally take the card block 21 out of the positioning slot 111.
