Description

Technical Field

[0001] The utility model relates to a cable joint, in particular to a cable joint with a sealing mechanism. Background Art

[0002] Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints. The cable joint in the middle of the cable line is called the intermediate joint, and the cable joints at both ends of the line are called terminal heads. Cable joints are used to lock and fix the incoming and outgoing lines, and can play a role in waterproofing, dustproofing and vibration prevention.

[0003] Cables are often laid in cable trenches, tunnels, pipes or indoors. After entering modern society, due to the shortage of urban land, heavy traffic pressure, urban appearance construction and other reasons, large cities generally adopt underground cable transmission methods. However, this method buries the cables underground for a long time, and the cable joints are affected by pressure or rainy weather for a long time. If a joint fails underground, it may cause hours of network downtime or power outages and high maintenance costs and affect nearby residents. Therefore, the cable joints must have strict sealing properties to ensure their complete sealing effect.

[0004] Therefore, the utility model provides a cable connector with a sealing mechanism. Utility Model Content

[0005] In order to overcome the disadvantage of insufficient sealing of existing cable joints underground, the utility model provides a cable joint with a sealing mechanism.

[0006] The technical scheme of the utility model is: a cable joint with a sealing mechanism, comprising a joint I, a joint II, an extrusion block, a spring, an extrusion rod, a wedge block, a limit block, a sealing ring I and a reinforcement component, the interface ends of the two cables are respectively slidably sleeved with a joint I and a joint II, the connection position of the joint I and the joint II is fixedly connected with a sealing ring I, the upper and lower parts of the joint I and the joint II are both provided with square holes, the upper and lower parts of the connection ends of the joint I and the joint II are fixedly connected with limit blocks, the limit blocks are fixedly connected with an extrusion block, the two extrusion blocks are internally connected with two extrusion rods, a wedge block is slidably penetrated between the corresponding two extrusion rods, a spring is arranged between the wedge block and the extrusion rod, a clamping groove is opened in the middle of the bottom of the wedge block, the connection ends of the joint I and the joint II are located in the clamping groove, the wedge block fixes the joint I and the joint II through the clamping groove, and the two sides of the bottom of the wedge block are inserted into the corresponding square holes on the joint I and the joint II.

[0007] In one embodiment, the reinforcement assembly includes a fixing block and a fixing rod, the left and right ends of the cable are fixedly connected with the fixing blocks, and the two fixing blocks are symmetrically fixedly connected with the fixing rod front and back.

[0008] In one of the embodiments, a sealing ring II is further included, and a sealing ring II is bonded to the cable connection portion where the connector I and the connector II are connected to each other on the side away from each other.

[0009] In one of the embodiments, a curved plate is further included, and the bottom of each of the extrusion rods is connected to the curved plate.

[0010] In one embodiment, the curved plate is made of waterproof rubber material.

[0011] In one embodiment, the arc-shaped plates are sleeved on the outside of the cable in a circular array.

[0012] The beneficial effects are as follows: 1. The utility model avoids the disadvantage of cable joints being damaged by infiltration of debris due to poor sealing by arranging sealing rings I and II between joints I and II, thereby achieving the effect that the cable can still be safely sealed when buried underground.

[0013] 2. The utility model provides a fixing block and a fixing rod, which can more completely fix the cable through close cooperation, thereby avoiding the disadvantage of loosening of the cable joint and achieving the effect of fixing the cable joint underground.

[0019] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0020] Embodiment: A cable connector having a sealing mechanism, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a joint Ⅰ1, a joint Ⅱ2, an extrusion block 3, a spring 4, an extrusion rod 5, a wedge block 6, an arc plate 7, a limit block 8, a fixed block 11, a fixed rod 12, a sealing ring Ⅰ9 and a sealing ring Ⅱ10. The butt ends of the two cables 13 are respectively slidably sleeved with joints Ⅰ1 and joints Ⅱ2. The contact position of the joint Ⅰ1 and the joint Ⅱ2 is bonded with a sealing ring Ⅰ9. The side of the joint Ⅰ1 and the joint Ⅱ2 that is away from each other is glued with a sealing ring Ⅱ10 at the connection point of the corresponding cable 13. The upper and lower parts of the joint Ⅰ1 and the joint Ⅱ2 are both provided with square holes 602. The left and right ends of the two cables 13 are fixedly connected to the fixed block 11. The two fixed blocks 11 are symmetrically bolted with a fixed rod 12, and the joint Ⅰ1 and the joint Ⅱ2 are connected. The upper and lower ends are connected to the limiting block 8 by bolts, and the top of the limiting block 8 is fixedly connected to the extrusion block 3. Two extrusion rods 5 that are symmetrical on the left and right are connected to the inside of the two extrusion blocks 3. A wedge block 6 is slidably passed between the corresponding two extrusion rods 5. A spring 4 is installed between the wedge block 6 and the extrusion rod 5. A clamping groove 601 is opened in the middle of the bottom of the wedge block 6. The connecting ends of the joint Ⅰ1 and the joint Ⅱ2 are located in the clamping groove 601. The wedge block 6 fixes the joint Ⅰ1 and the joint Ⅱ2 through the clamping groove 601, and the two sides of the bottom of the wedge block 6 are inserted into the corresponding square holes 602 on the joint Ⅰ1 and the joint Ⅱ2. The bottom of the extrusion rod 5 is connected with an arc plate 7, and the arc plate 7 is made of waterproof rubber material. The arc plate 7 is bonded to the outside of the cable 13 in a circular array.

[0021] When the cable 13 needs to be buried underground for a long time, the cable 13 to be buried underground can be prepared, and then the device can be taken out to connect the cable 13, and the connector of the cable 13 to be connected is taken out, and then the connector Ⅰ1 and the connector Ⅱ2 are put on the corresponding cable 13, and the cable 13 is connected, and then the connector Ⅰ1 and the connector Ⅱ2 are butt-jointed together, and then the fixing block 11 and the fixing rod 12 are connected together by bolts. After the fixing block 11 and the fixing rod 12 are connected, the limit block 8 is connected between the connector Ⅰ1 and the connector Ⅱ2 by bolts, so that the extrusion block 3 will drive the extrusion rod 5 and the arc plate 7 to press against the cable 1 3, thereby ensuring that the cable connection is more stable, and when the limit block 8 is installed, the two sides of the bottom of the wedge block 6 will be inserted into the corresponding square holes 602 on the connector I1 and the connector II2, and the connecting ends of the connector I1 and the connector II2 will also be inserted into the clamping groove 601 in the middle of the bottom of the wedge block 6. When the connecting ends of the connector I1 and the connector II2 are inserted into the top of the clamping groove 601, if the connecting ends of the connector I1 and the connector II2 are too long, the two wedge blocks 6 will move to the side away from each other. At this time, the spring 4 is compressed, so that under the action of the wedge block 6, the connector I1 and the connector II2 can be better clamped together to ensure the stability of the cable connection.

[0022] At the same time, sealing rings I and II are provided at each connection port of connector I1 and connector II2, which can prevent debris from penetrating into the interior of the cable connector 13 and better seal connector I1 and connector II2 to achieve a sealing effect.

Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
