Description

Technical Field

[0001] The present invention relates to the technical field of fixed protectors, and more particularly to a fixed protector for data communication cables. Background Art

[0002] Data transmission usually requires connecting different devices or networks, so data communication cables often need to be connected, and the connections usually need to be sealed and fixed for protection. The sealing and fixing of the connections have the following effects: 1. Waterproof and moisture-proof: prevent moisture from penetrating into the connections and protect the cables from moisture; 2. Dust-proof protection: prevent dust, debris and other pollutants from entering the connections, and reduce poor line contact and failures caused by dust; 3. Prevent mechanical damage: prevent the connections from being messed up or pulled by external objects, and reduce connection failure or cable damage caused by mechanical damage; 4. Improve reliability: ensure the connection quality of connectors and cables, and improve the reliability and stability of data transmission; 5. Enhance durability: extend the service life of connectors and cables, and reduce maintenance frequency and repair costs.

[0003] In the field of rail transit, rail transit vehicles will generate continuous vibrations and occasional impacts during operation. These vibrations and impacts come not only from the movement of the vehicle itself, but also from the unevenness of the track, bends, braking and acceleration. These forces will cause huge stress on the cable connections, which can easily lead to loose connections, breakage or performance degradation. In addition, rail transit is located underground, and the underground environment is relatively humid. The water vapor in the humid environment will penetrate into the cable connections, resulting in reduced insulation performance of the cables and increasing the risk of leakage and short circuit.

[0004] Currently, the most commonly used cable fixing protectors are clamps and clamp-type fixing clips. After the cable connecting plug and the connecting socket are plugged in, the connection is strengthened by the clamp, but the clamp cannot provide sufficient connection strength, resulting in the cable connection being easily loose or disconnected under external forces such as vibration and impact. Secondly, the sealing of the clamp connection is poor, and external pollutants such as water and dust can easily invade the connection and cause cable failure. Summary of the invention

[0005] The present invention provides a data communication cable fixing protector, which solves the technical problem in the prior art that a clamp and a clamp-type fixing clamp cannot provide sufficient connection strength and sealing performance.

[0006] The present invention provides a data communication cable fixing protector, comprising a left-right symmetrical wire harness and a wire harness connecting end arranged between the two wire harnesses, wherein the wire harness is composed of a plurality of cables, and left-right symmetrical connecting units are arranged on the outer sides of the two wire harnesses, and the connecting units include a sealed wire management component and a multi-stage connecting component.

[0007] The sealed wire management assembly includes a wire management ring sleeved on the outside of the wire harness and a sealed wire cover fixedly sleeved on the outside of the wire management ring, the sealed wire cover is threadedly connected to the outside of the sealed connecting ring, the multi-stage connection assembly includes an inner connecting cover fixedly installed on the outside of the sealed connecting ring, the sealing connecting ring is provided with a threaded groove on the side away from the sealed wire cover, the threaded groove is threadedly connected to a threaded barrel, the threaded barrel is threadedly connected to an outer connecting cover, and the outer connecting cover is threadedly connected to the inner connecting cover.

[0008] When connecting, first put the outer connecting cover on the outside of the wire harness, then put the wire management ring on the outside of the wire harness to separate the cables for combing, then put the sealed wire cover on the outside of the combed wire harness and screw the sealing connecting ring thread on the outside of the sealed wire cover to lock the sealed wire cover and complete the installation of the inner connecting cover, then connect the wire harness connecting end to the wire harness and connect the two wire harnesses through the wire harness connecting end, then screw the threaded barrel into the threaded groove, and finally screw the outer connecting cover thread into the threaded barrel. During the screwing process, the outer connecting cover is synchronously screwed with the inner connecting cover thread for double locking and sealing.

[0009] Furthermore, the wire management ring is composed of an outer ring and a wire combing plate fixedly installed on the inner wall of the outer ring. The outer ring and the wire combing plate are both made of rubber material, and an opening is provided on the outer side of the outer ring. The number of wire combing plates corresponds to the number of cables in the wiring harness.

[0010] Furthermore, the sealed wire harness cover is composed of an upper cover body and a lower cover body. After the upper cover body and the lower cover body are spliced ​​together, the two ends of the sealed wire harness cover form a number of sealing holes corresponding to the number of cables in the wire harness and the number of combing plates. A sealing ring is provided on the inner wall of the sealing hole, and the diameter of the sealing hole is consistent with the diameter of the cable to improve the sealing performance of the sealed wire harness cover.

[0011] Furthermore, an annular groove matching the width of the wire management ring is provided on the inner wall of the sealed wire harness cover, and the wire management ring is embedded in the annular groove.

[0012] Furthermore, the outer connection cover is provided with a plurality of sealing circular holes corresponding to the sealing hole and having the same diameter as the sealing hole on one side away from the sealing harness cover, and a sealing ring is provided on the inner wall of the sealing circular hole, and the diameter of the sealing circular hole matches the cable diameter to seal the inside of the two outer connection covers.

[0013] Furthermore, the wiring harness connection end includes a connection plug fixedly connected to the left wiring harness and a connection socket fixedly connected to the right wiring harness. The connection plug is threadedly connected to the outside of the left sealed wiring harness cover, and the connection socket is threadedly connected to the outside of the right sealed wiring harness cover. The connection plug and the connection socket are assembled and connected.

[0014] The beneficial effects of the present invention are:

[0015] The two wiring harnesses are initially connected by plugging the connecting plug and the connecting socket into each other, and then the sealing connecting ring is threadedly screwed on the outside of the sealing harness cover to perform secondary reinforcement on the locking fixation between the upper cover body and the lower cover body, and at the same time, the two inner connecting covers are threadedly screwed and locked synchronously, thereby achieving the secondary reinforcement of the sealing harness cover while strengthening the connection strength between the two wiring harnesses, thereby achieving secondary connection of the wiring harnesses, and then in the process of the outer connecting cover being threaded into the threaded barrel, the outer connecting cover will also be threadedly connected and locked with the inner connecting cover, thereby further strengthening the connection strength between the two wiring harnesses, thereby achieving three connections of the wiring harnesses, and then realizing an integrated multi-level fixed connection between the two cable harnesses, making the cable connection more stable, reducing the risk of loose or disconnected connection due to vibration, impact and other factors, thereby greatly improving the connection strength and connection stability of the cable.

[0016] A sealing hole is formed by splicing the upper cover body and the lower cover body, and the wiring harness connection is initially sealed under the action of the sealing hole. At the same time, when the two inner connecting covers are threadedly screwed and locked, the sealing rings between the two inner connecting covers are pressed and sealed against each other, thereby achieving secondary sealing of the wiring harness connection. Then, when the outer connecting cover and the inner connecting cover are threadedly connected and locked, the sealing rings between the two outer connecting covers are also pressed and sealed against each other, thereby achieving tertiary sealing of the wiring harness connection. Moreover, under the action of the sealing ring on the inner wall of the sealing circular hole, the inside of the outer connecting cover can be sealed, thereby achieving tertiary sealing of the wiring harness connection, thereby ensuring high sealing of the cable connection, effectively preventing the intrusion of external factors such as water and dust, and improving the reliability and durability of the cable connection.

[0017] The outer ring is stretched out and sleeved on the outside of the wire harness and the combing plate is inserted between adjacent cables to separate and comb the cables, thereby achieving orderly combing of the cables and avoiding confusion and entanglement between the cables, which not only improves the aesthetics of the cables, but also helps to reduce wear and damage of the cables caused by mutual friction.

[0032] The operating principle of the present invention is described as follows: when connecting, first pass the plurality of cables in the harness 1 through the sealed circular holes on the outer connection cover 3023 in sequence, so that the outer connection cover 3023 and the threaded tube 3022 are sleeved on the outside of the harness 1, and the inner connection cover 3021 is also sleeved on the outside of the harness 1 to wait for installation, then, the outer ring is stretched and sleeved on the outside of the harness 1 and the combing plate is inserted between adjacent cables to separate and comb the cables, and then the upper cover body and the lower cover body are relatively joined and spliced ​​(such as Figure 5As shown in Figure a), the upper cover body and the lower cover body are kept in a spliced ​​state, so that a complete sealed harness cover 3012 is formed on the outer side of the upper cover body and the lower cover body.

[0034] Then, screw the threaded barrel 3022 into the threaded groove 3024 on the sealing connection ring 3013 (such as Figure 5 As shown in Figure d in the middle), the outer connection cover 3023 that has been sleeved on the outside of the wiring harness 1 is then screwed into the threaded barrel 3022 until the outer connection cover 3023 abuts against the end of the sealed wire cover 3012 and the inner connection cover 3021. At the same time, when the outer connection cover 3023 is screwed into the threaded barrel 3022, the outer connection cover 3023 is also threadedly connected and locked with the inner connection cover 3021. When the outer connection cover 3023 abuts against the ends of the sealed wire cover 3012 and the inner connection cover 3021, the sealing rings between the two outer connection covers 3023 are also pressed and sealed against each other (as shown in Figure d in the middle).
