Description

Technical Field

[0001] The invention belongs to the technical field of cable assemblies, and in particular is a cable assembly with a water-proof function. Background Art

[0002] As the electrification of special vehicles, mobile power stations, and large machinery increases, more and more cable assemblies are used on the equipment to meet the connection of electrical lines. Because these equipment are used outdoors for a long time, cable assemblies often work in harsh environments such as vibration, rain, and dust. In order to improve the safety and reliability of equipment operation, the protection level of cable assemblies is generally required to reach at least IP54 - that is, it cannot completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the electrical equipment, and prevent water splashing from all directions from intruding.

[0003] In the existing cable assembly technology, there are usually two ways to connect cable assemblies and cable connectors. One is to connect them in an integrated manner, such as a flexible cable connection assembly with publication number CN211428888U. This connection method often leads to the scrapping of the entire assembly when the connector is damaged, which not only causes a waste of resources, but also brings inconvenience to maintenance and replacement. The other is to assemble by splicing multiple parts and components, such as a cable connection assembly with publication number CN206619746U. This splicing method has certain defects in sealing performance. Water vapor and water droplets can easily penetrate into the cable assembly through the tiny gap at the connection, causing cable damage and performance degradation. For this reason, a cable assembly with anti-immersion function is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0041] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See also Figure 1-Figure 9 The present application provides a cable assembly 3 with anti-immersion function, including a cable connector and a cable assembly 3, the cable connector including a base 1 and a rotating shell 2 rotatably mounted on the base 1, the rotating shell 2 is provided with anti-slip lines 21, which are used to increase the friction between the operator's hand and the operator's hand, and is easy to operate, and the cable assembly 3 is provided with a flexible sleeve 5, one end of the flexible sleeve 5 is hot-melted on the outer wall of the cable assembly 3, and the other end of the flexible sleeve 5 is sleeved and fitted on the outer side of the connecting piece 11, and also includes a sealing mechanism 7 arranged on the base 1 and on the inner side of the rotating shell 2, which is used to press and seal the flexible sleeve 5, a one-way limiting mechanism 8, which is arranged on the rotating shell 2, which is used to lock the rotating shell 2 on the base 1, a caulking mechanism 9, which is arranged on the base 1, which is used to fill the gap between the flexible sleeve 5 and the cable connector, and a clamping mechanism 10, which is arranged on the base 1, which is used to clamp and fix the cable assembly 3 connected to the cable connector;

[0044] The base 1 is provided with a No. 1 slide groove 13 arranged in an annular array, the sealing mechanism 7 includes a plurality of sliders 71 respectively slidably installed in the No. 1 slide groove 13, and each No. 1 slide groove 13 is provided with a No. 1 return spring 72 for returning the slider 71, a connecting block 73 is fixedly installed on the slider 71, a limit block 74 with an arc-shaped top surface is fixedly installed on one end of the connecting block 73, and a sleeve pressing block 75 is fixedly installed on the other end of the connecting block 73, a plurality of arc-shaped protrusions 6 arranged in an annular array and used for cooperating with the limit block 74 are fixedly installed on the inner wall of the rotating shell 2, a copper conductor element 14 for connecting to the cable assembly 3 is also provided on the base 1, and the copper conductor element 14 is arranged on the inner side of the conduit 111, and an annular protrusion 113 is also fixedly installed on the conduit 111, and the sleeve pressing block 75 is arranged between the two annular protrusions 113.

[0045] Specifically, by sleeved the flexible sleeve 5 on the outer wall of the cable assembly 3, and then connecting the cable assembly 3 with the copper conductor element 14 on the base 1 to form a passage, the conductive function can be achieved, and then one end of the flexible sleeve 5 is fixed to the outer wall of the cable assembly 3 by hot melting to ensure the sealing of the connection, and the other end of the flexible sleeve 5 is sleeved on the outer wall of the annular protrusion 113. In order to solve the problem that the hot melter is not convenient to insert into the cable connector to hot melt the flexible sleeve 5, after the expansion glue is injected, the rotating shell 2 can be rotated to drive the multiple arc-shaped protrusions 6 on the inner wall of the rotating shell 2 to rotate. Since the arc surface of the arc-shaped protrusion 6 and the arc surface of the limit block 74 fit each other, the multiple arc-shaped protrusions 6 can push the multiple limit blocks 74 toward the direction of the connecting piece 11 one by one. In this process, the slider 71 slides along the groove of the No. 1 slide groove 13, and the No. 1 return spring 72 is used to connect the block 73 is reset, and multiple sleeve pressing blocks 75 connected by connecting block 73 and limit block 74 can form a complete circular ring to press the flexible sleeve 5 between the two annular protrusions 113, and the pressed part of the flexible sleeve 5 is recessed inward and compacted with the expansion glue seal to form a sealed connection. At this point, further sealing between the cable assembly 3 and the cable connector is achieved, and the original cable assembly 3 and the cable connector are changed to adopt an integrated molding manufacturing method during the production process. After the cable assembly 3 is connected to the cable connector, if the cable inside the connector has poor contact, the entire cable connector needs to be removed and discarded and cannot be used again, resulting in a waste of resources. In addition, this method uses a compression method for the end of the sealing mechanism 7 inserted into the cable connector to avoid the problem of inconvenience caused by the hot melter inserted into the cable connector to perform hot melting on the flexible sleeve 5.

[0046] Embodiment 2:

[0047] On the basis of the first embodiment, the caulking mechanism 9 includes a fixed seat 91 fixedly mounted on the outer wall of the base 1, an L-shaped pressure block 92 is slidably mounted on the fixed seat 91, a No. 3 reset spring 93 for resetting the L-shaped pressure block 92 is arranged between the L-shaped pressure block 92 and the fixed seat 91, and a transmission rod 94 is also fixedly mounted on the L-shaped pressure block 92, and a piston is detachably mounted on the lower end of the transmission rod 94, and the caulking mechanism 9 also includes an annular storage box 96 fixedly mounted on the outer wall of the base 1, a sealing sleeve 95 is connected through the annular storage box 96, and the piston is slidably arranged inside the sealing sleeve 95, and a box cover 97 is also detachably mounted on the annular storage box 96, and a plurality of connecting pipes 98 arranged in an annular array are installed through the annular storage box 96, and the connecting pipes 98 are arranged through the base 1, and the base 1 also includes a connecting member 11, and the connecting member 11 includes a conduit 111 fixedly mounted on the inner wall of the base 1, and the conduit 111 is provided with a glue inlet groove 112 arranged in an annular array and connected through a plurality of corresponding connecting pipes 98.

[0048] Specifically, before the flexible sleeve 5 is pressed tightly against the connector 11 by the sealing mechanism 7, the transmission rod 94 is driven to move downward by pressing the L-shaped pressing block 92 downward, and the piston at the lower end of the transmission rod 94 slides inside the sealing sleeve 95. Since the sealing sleeve 95 and the piston are in a sealed state, the expansion glue inside the annular storage box 96 can enter the glue inlet groove 112 through the connecting pipe 98. The box cover 97 provided on the annular storage box 96 can add expansion glue to the inside of the annular storage box 96 to prevent the expansion glue inside the annular storage box 96 from being used up. The expansion glue enters from the glue inlet groove 112 and fills the gap between the conduit 111, the annular protrusion 113 and the flexible sleeve 5. After the expansion glue expands and solidifies, a waterproof barrier is formed, which prevents water vapor and water droplets from penetrating between the cable assembly 3 and the cable connector. Compared with the traditional splicing assembly method, the waterproof effect is better and the operation is simple.

[0049] Embodiment three:

[0050] On the basis of embodiment one, the one-way limiting mechanism 8 includes a limiting rod 81 slidably mounted on the rotating shell 2, a guide strip 82 is fixedly mounted on the limiting rod 81, and a No. 2 reset spring 83 is arranged between the limiting rod 81 and the rotating shell 2 for resetting the limiting rod 81; the base 1 is also provided with a plurality of limiting grooves 12 arranged in a ring array and used in conjunction with the limiting rod 81.

[0051] Specifically, when the rotating shell 2 slides on the base 1, the inclined surface at the end of the limit rod 81 is squeezed with a single limit groove 12 on the base 1, pushing the limit rod 81 to slide inside the rotating shell 2, and in this process, the No. 2 return spring 83 is compressed, and when the limit rod 81 is aligned with a certain limit groove 12, then under the action of the elastic force of the No. 2 return spring 83, the limit rod 81 is pushed into the inside of this limit groove 12 to complete the limiting. The function of the guide strip 82 is to prevent the limit rod 81 from rotating and causing the direction of the limit rod 81 to be disordered, and then adjust the relative positions of the arc-shaped protrusion 6 and the sealing mechanism 7, that is, it can realize the compression and release of the flexible sleeve 5, and can facilitate the direct separation of the cable assembly 3 from the cable connector after the cable connector is damaged or the cable assembly 3 and the cable connector are in poor contact, so as to facilitate maintenance.

When the rotating shell 2 is inserted into the conduit 111 and connected with the copper conductor element 14, the outer wall of the cable assembly 3 squeezes the clamping block 103, and the clamping block 103 slides along the guide shaft 101. During this process, the No. 4 return spring 102 is used to push the clamping block 103, so that the plurality of clamping blocks 103 limit and fix the cable, so as to avoid the cable assembly 3 shaking inside the internal conduit 111 after being connected to the copper conductor element 14, resulting in the continuous friction between the skin of the cable assembly 3 and the end of the conduit 111, causing the label of the cable assembly 3 to crack and water to enter.

[0054] Embodiment five:

[0055] On the basis of embodiment one, a protective shell 4 is further provided on the cable assembly 3, and the protective shell 4 is arranged on the outside of the flexible sleeve 5. The protective shell 4 and the cable assembly 3 are sealed and connected by a sealing ring 42, and an external thread 41 is provided on the protective shell 4; a thread groove 22 used in conjunction with the external thread 41 is also provided on the rotating shell 2. In order to prevent the flexible sleeve 5 from direct contact with the air, the external thread 41 is provided on the outside of the flexible sleeve 5, and the external thread 41 on the protective shell 4 is screwed into the thread groove 22 on the rotating shell 2 to protect the flexible sleeve 5.
