Referring to fig. 1, the present embodiment provides a cable sealing device 100, which is mainly used for sealing a cable 200, and can reduce the probability of air leakage of the cable 200 during the process of performing air tightness detection on an electronic device, thereby quickly completing the air tightness test of the electronic device.

The cable sealing device 100 provided by the embodiment can be used for sealing the cable 200 of the electronic equipment, and reduces the problem of inaccurate air tightness detection caused by air leakage of the cable 200 in the process of air tightness detection of the electronic equipment.

The cable sealing device 100 provided by the embodiment is mainly used for reducing gaps between the single wires and the shell, so that the air leakage probability of the cable 200 is reduced.

In the present embodiment, the cable sealing device 100 includes a fixing member 120 and a clamping member 110 disposed on the fixing member 120, wherein the clamping member 110 is used for clamping the cable 200 to seal the cable 200.

In this embodiment, the clamping member 110 is disposed on the fixing member 120 and fixed by the fixing member 120, the clamping member 110 is used for clamping the cable 200, and reducing gaps between the plurality of single wires and between the single wires and the housing, thereby sealing the cable 200, preventing the electronic device from leaking gas between two adjacent single wires or between the single wire and the housing during the process of detecting the air tightness, and affecting the air tightness detection of the electronic device, and being capable of quickly completing the air tightness test of the electronic device.

Referring to fig. 2, in the present embodiment, the clamping member 110 has a clamping hole 112, an aperture of the clamping hole 112 is smaller than a diameter of the cable 200, and the clamping member 110 mainly clamps the cable 200 through the clamping hole 112.

In this embodiment, the cable 200 passes through the clamping hole 112, and the clamping member 110 exerts a force on the cable 200 located in the clamping hole 112 to press the cable 200, so that the two adjacent single wires or the adjacent single wires and the housing can be attached to each other, and the gap between the two adjacent single wires or the gap between the adjacent single wires and the housing is reduced, thereby reducing the air leakage of the cable 200.

In the present embodiment, the cable 200 passes through the clamp hole 112 and abuts against the hole wall forming the clamp hole 112, and the hole wall of the clamp hole 112 applies a continuous pressure to the cable 200 from the circumferential direction of the cable 200 to perform the clasping sealing treatment on the cable 200, thereby reducing the gap between the cables 200 and improving the airtightness of the cable 200.

In the present embodiment, due to the powerful action between the clamping member 110 and the cable 200 and due to the existence of the guide groove, in order to ensure the airtightness and the working performance of the cable 200 during the interaction with the cable, the diameter of the clamping hole 112 is changed, and the variation of the diameter of the clamping hole 112 in the vertical section of the cable 200 is controlled to be 10% -50%, preferably about 20%, of the diameter of the cable 200, so as to ensure that the clamping member 110 clamps the cable 200 without being damaged by excessive clamping force.

In the present embodiment, the contact area of the surface forming the clamping hole 112 and the cable 200 may be 2 times or more the diameter of the cable 200.

In this embodiment, the clamping member 110 is further provided with a guide groove 114, and the guide groove 114 extends from one end of the clamping member 110 to the clamping hole 112.

In this embodiment, the cable 200 is gradually slid along the guide groove 114 to the clamping hole 112 from the end of the guide groove 114 away from the clamping hole 112. When the airtightness detection of the electronic device is completed, the cable 200 is gradually slid along the guide groove 114 from the clamping hole 112, thereby being taken out from the clamping member 110.

In the present embodiment, the clamping member 110 is detachably mounted in the fixing hole 122, and the outer wall of the clamping member 110 detachably abuts against the inner wall of the fixing hole 122. The clamping piece 110 of different apertures is changed according to the size of different cables 200, thereby realizing the tight holding and sealing of different cables 200 or different quantities of gas leakage cables 200, realizing the multiplexing of the cable sealing device 100, improving the use efficiency of the cable sealing device 100, being convenient to disassemble and assemble, and ensuring the sealing effect of the cables 200.

In this embodiment, the bottom walls of the abutting part 130 and the first end 124 respectively play a role in limiting the clamping part 110 from two sides of the clamping part 110, and in the process of detecting the air tightness of the electronic device, the installation section 116 can be always located in the second end 126 to prevent the clamping part 110 from being ejected from the fixing part 120, so that the second end 126 applies continuous pressing force to the installation section 116 along the circumferential direction of the installation section 116 to reduce the gap of the cable 200, thereby playing a role in sealing the cable 200.

In the present embodiment, the abutting member 130 includes an abutting portion 132 and a connecting portion 134, the connecting portion 134 is connected with the fixing member 120 to form a sliding slot 136, and the abutting portion 132 is inserted into the sliding slot 136 (see fig. 3).

After the abutting portion 132 abuts against the clip 110, the clip 110 can be prevented from falling out of the fixing member 120 during the airtightness test of the electronic apparatus.

In the present embodiment, the contact portion 132 slides in the slide groove 136, and gradually comes into contact with the clip 110 while sliding toward the second stopper portion 129, and when the contact portion 132 comes into contact with the second stopper portion 129, it indicates that it is completely attached to the clip 110.
