Description

Technical Field

[0001] The utility model belongs to the field of intermediate joint protection devices, and specifically relates to a cable intermediate joint protection device. Background Art

[0002] A cable joint is also called a cable head. After the cable is laid, in order to make it a continuous line, each section of the wire must be connected into a whole, and these connection points are called cable joints.

[0003] Chinese Patent with publication number CN217115584U discloses a cable harness intermediate joint protection device. In paragraph 23 of the specification, it is disclosed that first, the surface of the intermediate sleeve is placed in contact with the inner wall of the lower shell, and then the pin board in the upper shell is inserted into the insertion slot provided on the surface of the lower shell, and a sealing ring is sleeved between the surfaces of the first arc-shaped shell and the second arc-shaped shell, so that the upper shell and the lower shell can provide good sealing protection for the cable body in the intermediate sleeve;

[0004] However, for the above-mentioned cable harness intermediate joint protection device, the sealing ring and the fixing sleeve need to be sleeved on the cable body in advance. If the staff forgets to sleeve the sealing ring and the fixing sleeve in advance when installing the cable body, the cable body needs to be removed and the sealing ring and the fixing sleeve need to be sleeved again, resulting in low operation convenience, and it takes multiple turns of the fixing sleeve thread to complete the fixing, with low fixing efficiency.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0006] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a cable intermediate joint protection device.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this embodiment provides a cable joint protection device, including:

[0030] Intermediate joint 1, wherein cable bodies 101 are provided at both ends of the intermediate joint 1;

[0031] The protection mechanism 2 includes an upper housing 201 and a lower housing 202. The upper housing 201 and the lower housing 202 are both sleeved on the intermediate joint 1 and the cable body 101. Two U-shaped frames 203 are fixed on the upper housing 201. The U-shaped frames 203 are elastically slidably fitted with limit pins 204 on their inner sides. U-shaped pull plates 205 are elastically slidably fitted inside the U-shaped frames 203 to compress the sliding of the two limit pins 204.

[0032] After the cable body 101 is installed, the U-shaped bracket 203 on the upper housing 201 is inserted into the lower housing 202. When the limiting pin 204 enters the lower housing 202, the lower housing 202 squeezes the limiting pin 204, and the limiting pin 204 squeezes the U-shaped pull plate 205 to slide, so that the limiting pin 204 is retracted into the U-shaped bracket 203. When the limiting pin 204 passes through the lower housing 202, the limiting pin 204 is automatically ejected by the U-shaped pull plate 205, which facilitates the quick positioning of the upper housing 201 and the lower housing 202, and no preparation is required before the cable body 101 is installed, which improves the convenience and efficiency of the installation of the protection mechanism 2.

[0033] Please see Figure 1-2 As shown, in this embodiment, the end faces and axial vertical sections of the upper housing 201 and the lower housing 202 are all "U" shaped structures. The upper housing 201 has two mounting holes 206 on its upper side, corresponding to the U-shaped frame 203. The lower part of the U-shaped frame 203 is fixed in the two mounting holes 206, which facilitates the U-shaped frame 203 to be fixed on the upper housing 201. The lower housing 202 has two through holes 207 on its upper side, which correspond to the lower part of the U-shaped frame 203, which facilitates the U-shaped frame 203 to pass through the lower housing 202 through the through holes 207.

[0034] To enable the U-shaped pull plate 205 and the limiting pin 204 to slide elastically, please refer to... Figure 1-3 As shown, in this embodiment, the U-shaped frame 203 has channels 208 on its inner sides, and a slide rail 209 is provided on the bottom surface of the inner wall of the channel 208. The U-shaped pull plate 205 is slidably engaged in the two channels 208 and the two slide rails 209. A spring 210 is provided between the inner wall of the channel 208 and the upper side of the U-shaped pull plate 205. The U-shaped frame 203 has guide channels 211 on its inner sides, and the guide channels 211 are connected to the channels 208. The limiting pin 204 is slidably engaged in the guide channel 211. A tension spring 212 is provided between the inner wall of the guide channel 211 and the limiting pin 204. The elastic force of the spring 210 is greater than that of the tension spring 212. 2. Elasticity: The bottom surface of the U-shaped pull plate 205 is provided with a first inclined surface, and the bottom surface of the limiting pin 204 extending out of the guide channel 211 is provided with a second inclined surface. The distance between the two first inclined surfaces gradually increases from the bottom to the top, and the distance between the two second inclined surfaces gradually increases from the bottom to the top. The bottom end of the U-shaped pull plate 205 is provided with a notch 213 corresponding to the tension spring 212, which facilitates the elastic sliding of the spring 210 through the U-shaped pull plate 205 and the elastic sliding of the limiting pin 204 through the tension spring 212. The U-shaped pull plate 205 can squeeze the limiting pin 204 to stretch the tension spring 212 to slide. By setting the notch 213, it is easy to avoid the tension spring 212 affecting the sliding of the U-shaped pull plate 205.

[0035] Working principle: After the cable body 101 is installed, the U-shaped bracket 203 on the upper housing 201 is inserted into the through hole 207 in the lower housing 202. When the limiting pin 204 enters the through hole 207, the lower housing 202 presses the second inclined surface on the limiting pin 204, and the limiting pin 204 presses the U-shaped pull plate 205 to slide, causing the limiting pin 204 to retract into the guide channel 211. When the limiting pin 204 passes through the through hole 207, the spring 210 automatically presses the limiting pin 204 through the U-shaped pull plate 205. The pop-out mechanism facilitates quick positioning of the upper housing 201 and lower housing 202 without requiring any preparation before installing the cable body 101, thus improving the convenience and efficiency of the protection mechanism 2 installation. When the protection mechanism 2 needs to be disassembled, hold the U-shaped frame 203 and pull the U-shaped pull plate 205 to slide. The tension spring 212 pulls the limit pin 204 back into the guide channel 211. Then, pull the U-shaped frame 203 to quickly separate the upper housing 201 and lower housing 202, which facilitates the disassembly of the protection mechanism 2.
