Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, and particularly relates to a joint protection device. Background Art

[0002] In order to realize the electrical connection between a cable and a power distribution cabinet, the plug at the end of the cable is inserted into the socket on the side of the power distribution cabinet, and the electrical connection between the cable and the power distribution cabinet can be realized. A round cover is hinged on the outer wall of the socket, and the plug can be inserted into the socket only after the round cover is opened. After the plug is inserted into the socket, the round cover is stuck at the block on the side of the plug under the elastic force of the torsion spring, so as to prevent the plug from being pulled and separated from the socket. After the plug is pulled out of the socket, the round cover is sleeved on the socket under the elastic force of the torsion spring to realize the waterproof and dustproof of the socket.

[0003] After the plug at the end of the cable is inserted into the socket, the electrical connection between the cable and the power distribution cabinet can be realized. At the same time, the plug can be prevented from separating from the socket under the clamping action of the round cover. However, the cable connected to the side of the power distribution cabinet is usually directly placed on the ground, and it is easy for a staff member to trip over the cable when passing by the power distribution cabinet. When the cable is pulled, the pulling force will directly act on the connection part between the plug and the cable, and the connection position between the cable and the plug is likely to become loose and have poor contact due to continuous stress. Therefore, the present application provides a joint protection device to meet the requirements. Content of the Utility Model

[0004] The utility model provides a joint protection device to solve the problem that when the cable is pulled, the pulling force will directly act on the connection part between the plug and the cable, and the connection position between the cable and the plug is likely to become loose and have poor contact due to continuous stress.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A joint protection device includes a socket and a plug inserted into the socket. An installation plate is fixed on the side of the socket for fixing the socket. A cover plate is hinged on the outer wall of the socket, and the cover plate is clamped at the block fixed on the outer wall of the plug. The cable is installed at the end of the plug away from the socket, and further includes:

[0007] A protection mechanism, the protection mechanism includes a support plate fixed on the side of the installation plate. A positioning column and a positioning seat are respectively fixed on the top of the support plate. The positioning seat is located between the positioning column and the installation plate, and the positioning column is fixed on the side of the installation plate. The positioning column is inclined, and the top of the positioning column inclines away from the installation plate. The end of the cable away from the plug passes through between the positioning column and the positioning seat, and the support plate is used for supporting the cable.

[0008] Preferably, a wrapping component is wrapped on the surface of the cable, and the wrapping component is located between the positioning column and the positioning seat.

[0009] Preferably, the wrapping component includes a semi-circular sleeve one and a semi-circular sleeve two that fit on the surface of the cable. The semi-circular sleeve one is detachably connected to the side of the semi-circular sleeve two. The outer wall of the semi-circular sleeve one fits against the circumferential surface of the positioning post. An arc surface is provided on the side of the positioning seat, and the outer wall of the semi-circular sleeve two fits against the arc surface.

[0010] Preferably, a guiding surface is provided at the top of the positioning seat. The guiding surface is inclined and is connected to the arc surface.

[0011] Preferably, a slider is fixed on the outer wall of the semi-circular sleeve one. An inclined groove is provided on the circumferential surface of the positioning post, and the slider is slidably connected in the inclined groove.

[0012] Preferably, the side of the slider away from the semi-circular sleeve one is inclined, and the shape of the slider is adapted to the shape of the inclined groove.

[0013] Preferably, two rubber blocks are fixed on the circumferential surface of the positioning post. The inclined groove is located between the two rubber blocks. Upper inclined surfaces and lower inclined surfaces are respectively provided at the top and bottom of the rubber blocks, and the lower inclined surface fits against the outer wall of the semi-circular sleeve one.

[0014] Preferably, a buffer groove is provided on the side of the rubber block.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above solution, by providing the support plate and the positioning post, the end of the cable away from the plug is passed through between the positioning post and the positioning seat, and the cable is supported by the support plate. When the cable is pulled, it slides over the inclined surface of the positioning post. After the cable slides over the positioning post, the reserved length between the cable corresponding to the positioning post and the plug can buffer the cable when it is pulled, thereby reducing the probability of loosening and poor contact at the connection position between the cable and the plug.

[0017] By providing the wrapping component, the semi-circular sleeve one and the semi-circular sleeve two of the wrapping component wrap the area of the cable corresponding to the positioning post and the positioning seat, and the semi-circular sleeve one and the semi-circular sleeve two are used to protect the surface of the cable, preventing the insulating layer of the cable from being worn by the positioning post when the cable slides over the positioning post.

[0018] By providing the slider, the semi-circular sleeve one and the semi-circular sleeve two wrap the cable. When the cable is pulled and slides upward along the inclined positioning post, the semi-circular sleeve one drives the slider to slide along the inner wall of the inclined groove on the positioning post. Through the cooperation of the slider and the inclined groove, the semi-circular sleeve one can only slide along the positioning post and will not cause the semi-circular sleeve one to have a horizontal displacement at the positioning post, thereby effectively preventing the connection between the cable and the plug from being pulled, and further preventing loosening and poor contact at the connection position between the cable and the plug.

[0019] By setting the rubber block, when the semi-circular sleeve one slides upward along the inclined positioning column, the rubber block provides resistance to the movement of the semi-circular sleeve one, preventing the cable from separating from the positioning column when slightly pulled. When the cable is pulled strongly, the semi-circular sleeve one will squeeze the rubber block, deforming the rubber block, and then the semi-circular sleeve one passes through the rubber block and disengages from the positioning column, thus realizing the buffering of the connection position between the cable and the plug.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following describes in detail a joint protection device provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present utility model.

[0029] As Figures 1-6 shown, an embodiment of the present utility model provides a joint protection device, which includes a socket 2 and a plug 1 inserted into the socket 2. A mounting plate 3 is fixed on the side of the socket 2 for fixing the socket 2. A cover plate 4 is hinged on the outer wall of the socket 2, and a torsion spring is installed at the hinge. The torsion spring provides elastic force for the cover plate 4. The cover plate 4 is clamped at the block fixed on the outer wall of the plug 1. The elastic force of the torsion spring acts on the cover plate 4, so that the cover plate 4 is stably clamped at the block on the outer wall of the plug 1. When the plug 1 is pulled out from the socket 2, the cover plate 4 covers the socket 2 under the action of the elastic force of the torsion spring, realizing the protection of the open end of the socket 2. A cable is installed at one end of the plug 1 away from the socket 2. A convex portion is integrally formed on the outer wall of the socket 2. A convex block is integrally formed on the outer wall of the plug 1 at a position corresponding to the convex portion. The convex block is stuck in the convex portion to prevent the plug 1 from rotating in the socket 2, thereby improving the connection stability between the plug 1 and the socket 2. It further includes:

[0030] A protection mechanism 5, the protection mechanism 5 includes a support plate 6 fixed on the side of the mounting plate 3. A positioning column 8 and a positioning seat 7 are respectively fixed on the top of the support plate 6. The positioning seat 7 is located between the positioning column 8 and the mounting plate 3, and the positioning column 8 is fixed on the side of the mounting plate 3. The positioning column 8 is inclined, and the top of the positioning column 8 is inclined away from the mounting plate 3. One end of the cable away from the plug 1 passes between the positioning column 8 and the positioning seat 7. The support plate 6 is used to support the cable. Through the inclined positioning column 8, when the cable is pulled, the cable can slide over the surface of the positioning column 8. After the cable slides over the positioning column 8, the reserved length of the cable between the positioning column 8 and the plug 1 can buffer the cable when it is pulled, thereby reducing the probability of loosening and poor contact at the connection position between the cable and the plug 1.

[0031] As Figures 1-4 shown, in this embodiment, a wrapping component 10 is wrapped on the surface of the cable. The wrapping component 10 is located between the positioning column 8 and the positioning seat 7. The wrapping component 10 can wrap the area of the cable corresponding to the positioning column 8 and the positioning seat 7, and use the structure of the wrapping component 10 to protect the surface of the cable and prevent the insulating layer of the cable from being worn by the positioning column 8 when the cable slides over the positioning column 8.

[0032] As Figures 2-4As shown in the figure, in this embodiment, the wrapping component 10 includes a semi-circular sleeve one 11 and a semi-circular sleeve two 12 that fit on the surface of the cable. The semi-circular sleeve one 11 is detachably connected to the side of the semi-circular sleeve two 12. Pass the bolt through the semi-circular sleeve one 11 and the semi-circular sleeve two 12, and then tighten the nut on the bolt to fix the semi-circular sleeve one 11 and the semi-circular sleeve two 12, thereby fixing the semi-circular sleeve one 11 and the semi-circular sleeve two 12 on the cable. Unscrew the nut and pull out the bolt from the semi-circular sleeve one 11 and the semi-circular sleeve two 12 to release the fixation of the semi-circular sleeve one 11 and the semi-circular sleeve two 12 on the cable. The outer wall of the semi-circular sleeve one 11 fits against the circumferential surface of the positioning post 8, and an arc surface is provided on the side of the positioning seat 7. The outer wall of the semi-circular sleeve two 12 fits against the arc surface. The semi-circular sleeve one 11 and the semi-circular sleeve two 12 can tightly wrap the cable to protect the cable. The arc surface of the positioning seat 7 fits against the semi-circular sleeve two 12, improving the stability of the wrapping component 10 placed between the positioning post 8 and the positioning seat 7 and ensuring the alignment state of the wrapping component 10 with the positioning post 8.

[0033] As Figure 4 and Figure 6 shown in the figure, in this embodiment, a guiding surface 18 is provided at the top of the positioning seat 7. The guiding surface 18 is inclined and connected to the arc surface. The guiding surface 18 can guide the wrapping component 10. When the wrapping component 10 is placed between the positioning post 8 and the positioning seat 7, the inclined guiding surface 18 can reduce the resistance during the installation of the wrapping component 10, reduce the installation difficulty, improve the positioning convenience of the cable, and enable the wrapping component 10 to be quickly and accurately placed at the predetermined position.

[0034] As Figure 3 and Figure 4 shown in the figure, in this embodiment, a slider 13 is fixed to the outer wall of the semi-circular sleeve one 11, and an inclined groove 9 is provided on the circumferential surface of the positioning post 8. The slider 13 is slidably connected in the inclined groove 9. When the cable is pulled and slides upward along the inclined positioning post 8, the semi-circular sleeve one 11 drives the slider 13 to slide upward along the inner wall of the inclined groove 9 on the positioning post 8. Through the cooperation of the slider 13 and the inclined groove 9, a horizontal limit is formed for the semi-circular sleeve one 11, ensuring that the semi-circular sleeve one 11 can only slide along the axial direction of the positioning post 8, preventing the connection between the cable and the plug 1 from being pulled, and thus preventing loosening and poor contact at the connection between the cable and the plug 1 due to pulling.

[0035] As Figure 4 shown in the figure, in this embodiment, the side of the slider 13 away from the semi-circular sleeve one 11 is inclined, and the shape of the slider 13 is adapted to the shape of the inclined groove 9. The adapted shape design enables the slider 13 to slide stably along the inner wall of the inclined groove 9, improving the guiding ability of the inclined groove 9 for the slider 13.

[0036] As Figure 2 and Figure 5As shown in the figure, in this embodiment, two rubber blocks 14 are fixed on the circumferential surface of the positioning post 8. The inclined groove 9 is located between the two rubber blocks 14. Upper inclined surfaces 15 and lower inclined surfaces 16 are respectively formed at the top and bottom of the rubber block 14. The lower inclined surface 16 is in contact with the outer wall of the semi-circular sleeve 11. The rubber block 14 can provide a buffering effect through elastic deformation. When the cable is slightly pulled, the elastic resistance of the rubber block 14 blocks the upward movement of the cable, keeping the cable in place and preventing the cable from separating from the positioning post 8 due to slight external force. When the pulling force is large, the semi-circular sleeve 11 moves upward along the positioning post 8 and squeezes the rubber block 14. While the rubber block 14 deforms, the semi-circular sleeve 11 is guided by the lower inclined surface 16 and passes by the rubber block 14, effectively reducing the resistance during the upward movement of the semi-circular sleeve 11. When the cable is placed between the positioning post 8 and the positioning seat 7, the semi-circular sleeve 11 is guided by the upper inclined surface 15, facilitating the semi-circular sleeve 11 to pass by the rubber block 14, thereby facilitating the placement of the cable between the positioning post 8 and the positioning seat 7.

[0037] As Figure 5 shown in the figure, in this embodiment, a buffer groove 17 is formed on the side surface of the rubber block 14. The buffer groove 17 provides space for the deformation of the rubber block 14, enabling the rubber block 14 to deform elastically more smoothly when being squeezed by the semi-circular sleeve 11 and preventing the rubber block 14 from being damaged due to excessive squeezing.

[0038] Working principle: When the cable is pulled by an external force, the cable drives the semi-circular sleeve 11 and the semi-circular sleeve 12 to move under the guiding action of the inclined positioning post 8. While the semi-circular sleeve 11 moves along the circumferential surface of the positioning post 8, the semi-circular sleeve 11 drives the slider 13 to move obliquely upward along the inner wall of the inclined groove 9. The cooperation between the inclined groove 9 and the slider 13 forms a horizontal limit for the semi-circular sleeve 11, ensuring that the semi-circular sleeve 11 can only slide along the axial direction of the positioning post 8, thereby preventing loosening and poor contact at the connection between the cable and the plug 1 due to pulling.

[0039] At the same time, the rubber block 14 on the circumferential surface of the positioning column 8 provides a buffering effect through elastic deformation. When the cable is slightly pulled, the elastic resistance of the rubber block 14 prevents the cable from moving upward, thereby keeping the cable in place. When the pulling force is large, the semicircular sleeve 11 moves upward along the positioning column 8 while squeezing the rubber block 14. The rubber block 14 is deformed after being squeezed, and the buffer groove 17 provides space for the deformation of the rubber block 14. After the rubber block 14 is deformed, the semicircular sleeve 11 can go over the rubber block 14 and continue to slide upward until the cable is detached from the positioning column 8, thereby achieving buffering protection for the connection between the plug 1 and the cable. In addition, the wrapping design of the semicircular sleeve 11 and the semicircular sleeve 2 12 protects the cable insulation layer from wear on the positioning column 8. The arc surface of the positioning seat 7 is adapted to the shape of the semicircular sleeve 2 12, which is used to improve the stability of the semicircular sleeve 2 12 placed between the positioning column 8 and the positioning seat 7. The guide surface 18 is used to guide the wrapping component 10 to be placed between the positioning column 8 and the positioning seat 7, thereby improving the convenience of cable positioning.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
