Description

Technical Field

[0001] The present application relates to the technical field of intercom cables, and in particular to a connecting cable. Background Art

[0002] A walkie-talkie is a two-way mobile communication tool that allows calls without any network support and without incurring any call charges. It is suitable for relatively fixed and frequent call situations. There are currently three types of walkie-talkies: analog walkie-talkies, digital walkie-talkies, and IP walkie-talkies. With the continuous development of communication technology, the use of walkie-talkies has become more and more popular.

[0003] When using the intercom, most of them need to be connected with a cable. The staff manually pushes the soft cable into and plugs it into the housing of the intercom.

[0004] Regarding the above-mentioned related technologies, since the intercom often needs to be moved, the connecting cable must also be moved accordingly with the position of the intercom. During the movement of the cable, its end may accidentally contact water or dust, affecting the connection between the cable and the intercom, and further interfering with the call quality of the intercom, so it needs to be improved. Utility Model Content

[0005] In order to facilitate the protection of cables and reduce the impact of external substances on the cables, the present application provides a connecting cable.

[0006] The present application provides a connecting cable that adopts the following technical solution:

[0007] A connecting cable comprises a cable body and a protective cover, wherein the protective cover is movably arranged on the cable body and close to one end of the cable body, and the protective cover moves along the length direction of the cable body; the protective cover is opened and forms a accommodating cavity, the connecting end of the cable body is located in the accommodating cavity, and the protective cover is used to protect the connecting end of the cable body.

[0008] By adopting the above technical solution, the connection end of the cable body is used to connect to the intercom. When the cable body is not connected to the intercom, the staff can apply external force to the protective cover to make the protective cover move on the cable body, and the protective cover gradually approaches the connection end of the cable body, thereby shielding and protecting the connection end of the cable body, reducing the impact of external substances (such as moisture and dust) on the cable, and facilitating the protection of the cable.

[0009] Preferably, the cable body includes an electric wire and a connector, and the protective cover is movably arranged on the electric wire; the connector is connected to one end of the electric wire, the cover opening of the protective cover faces the connector, and the protective cover is used to protect the connection.

[0010] By adopting the above technical solution, the connector is used to connect to the walkie-talkie. Before installing the connector on the cable body, the protective cover is first connected to the wire. The protective cover can slide on the wire through a certain external force; the side where the protective cover mouth is located is used to cover the connector, so that the connector is protected in the accommodating cavity.

[0011] Preferably, the outer surface of the electric wire is covered with an insulating layer, and the insulating layer is made of insulating material.

[0012] By adopting the above technical solution, the insulating layer can play an insulating and flame-retardant role for the wires, and the insulating material can be made of plastic materials, such as PVC polyethylene; it can also be made of rubber materials.

[0013] Preferably, a sliding sleeve is connected to a side of the protective cover away from the cover opening, and the sliding sleeve is slidably connected to the electric wire.

[0014] By adopting the above technical solution, when it is necessary to adjust the position of the protective cover relative to the wire, an external force can be applied to the sliding sleeve to cause sliding friction between the sliding sleeve and the wire, thereby realizing the movement of the protective cover.

[0015] Preferably, an annular groove is provided on the outer side wall of the sliding sleeve, and the annular groove is arranged along the circumference of the sliding sleeve; a plurality of the annular grooves are provided, and the annular grooves are spaced apart along the sliding direction of the sliding sleeve, and a convex pattern is formed between two adjacent annular grooves.

[0016] By adopting the above technical solution, when a worker touches the sliding sleeve with his hand, a plurality of convex patterns are formed on the outer surface of the sliding sleeve due to the presence of the annular groove, and the convex patterns can increase the contact friction between the hand and the sliding sleeve.

[0017] Preferably, the sliding sleeve is threaded onto the electric wire.

[0018] By adopting the above technical solution, the force that maintains the relative position between the sliding sleeve and the wire is mainly static friction. Once the external force exceeds this static friction, the sliding sleeve and the wire are prone to relative displacement. Now, by screwing the sliding sleeve on the wire, the stability of the position of the sliding sleeve on the wire is increased by relying on the screw connection force between the sliding sleeve and the wire; at the same time, the position of the sliding sleeve can be changed by rotating the sliding sleeve, and the rotational motion is converted into linear motion, thereby controlling the shielding and protection of the protective cover to the connector.

[0019] Preferably, a plurality of triangular portions are provided between the sliding sleeve and the protective cover, and the triangular portions are distributed at intervals along the circumference of the sliding sleeve.

[0020] By adopting the above technical solution, the triangular part further connects the sliding sleeve and the protective cover, plays a reinforcing role, and improves the stability of the connection between the two.

[0021] Preferably, the outer surface of the protective cover is provided with friction patterns.

[0022] By adopting the above technical solution, the staff needs to contact the protective cover when adjusting the position of the protective cover. The friction lines can increase the friction between the hand and the protective cover, thereby better applying force to the protective cover.

[0023] Preferably, the protective cover is made of plastic material.

[0024] By adopting the above technical solution, the protective cover made of plastic material has the advantages of light weight and low cost. On the premise of ensuring the most important protective function of the protective cover, the production cost is reduced and the weight of the entire cable is reduced.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] (1) By setting up a protective cover, the protective cover can shield and protect the connection end of the cable body, reduce the impact of external substances (such as moisture and dust) on the cable, and facilitate the protection of the cable.

[0027] (2) By setting a sliding sleeve, the sliding sleeve can increase the contact area between the protective cover and the wire connection. After external force is applied to the sliding sleeve and its position is changed, the protective cover will also move with the sliding sleeve.

[0028] (3) By providing the triangular portion, the triangular portion further connects the sliding sleeve and the protective cover, thereby playing a reinforcing role. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.

[0038] The present application embodiment discloses a connecting cable. Figure 1 and Figure 2The connecting cable includes a cable body 1 and a protective cover 2. The cable body 1 includes a wire 11 and a connector 12. The outer surface of the wire 11 is covered with an insulating layer (not shown in the figure). The insulating layer can insulate and flame retard the wire 11. The insulating layer is made of insulating material. The insulating material can use plastic material, such as PVC polyethylene; rubber material can also be used. The connector 12 is connected to one end of the wire 11, and the connector 12 is used to connect to the intercom. The protective cover 2 is movably connected to the wire 11 and close to the position where the connector 12 is located. The protective cover 2 moves along the length direction of the wire 11. The protective cover 2 is opened and formed with a accommodating cavity 3. The cover opening of the protective cover 2 faces the connector 12. The size of the accommodating cavity 3 is larger than the size of the connector 12, so that the connector 12 can be completely in the accommodating cavity 3. The protective cover 2 is used to protect the connector 12.

[0039] Specifically, a sliding sleeve 4 is fixedly connected to the side of the protective cover 2 away from the cover opening, and the sliding sleeve 4 is threadedly connected to the wire 11. When the staff applies force to control the sliding sleeve 4 to rotate, the rotational movement of the sliding sleeve 4 will be converted into a linear movement of the sliding sleeve 4 on the wire 11, thereby realizing the sliding of the sliding sleeve 4. An annular groove 5 is provided on the outer wall of the sliding sleeve 4, and the annular groove 5 is arranged along the circumference of the sliding sleeve 4; wherein, the annular groove 5 is provided with a plurality of annular grooves, and each annular groove 5 is spaced apart along the sliding direction of the sliding sleeve 4, and a convex pattern is formed between two adjacent annular grooves 5.

[0040] Before installing the connector 12, the cable body 1 first connects the sliding sleeve 4 and the protective cover 2 to the wire 11, and then connects the connector 12 to the wire 11. When the connector 12 is not connected to the intercom, the staff can apply a rotational external force to the sliding sleeve 4, so that the protective cover 2 moves on the wire 11 along with the sliding sleeve 4. At this time, the protective cover 2 gradually approaches the connector 12 until the connector 12 is located in the accommodating cavity 3, thereby shielding and protecting the connector 12, reducing the impact of external substances (such as moisture and dust) on the cable, and facilitating the protection of the cable.

[0041] In addition, when a worker touches the sliding sleeve 4 with his hand, the convex patterns can increase the contact friction between the hand and the sliding sleeve 4 due to the presence of the convex patterns, so as to better apply force to the sliding sleeve 4 for rotation.

[0042] According to some embodiments of the present application, optionally, please refer to Figure 2 A plurality of triangular parts 6 are fixedly connected at the connection position between the sliding sleeve 4 and the protective cover 2, and the triangular parts 6 are distributed at intervals along the circumference of the sliding sleeve 4. The triangular parts 6 further connect the sliding sleeve 4 and the protective cover 2, play a reinforcing role, and improve the stability of the connection between the two.

[0043] According to some embodiments of the present application, optionally, please refer to Figure 3The protective cover 2 can also be rotatably connected with a baffle 7. When the connector 12 is completely located in the accommodating chamber 3, the baffle 7 is used to cover the cover opening of the protective cover 2. The end of the baffle 7 away from its own rotation axis is connected to the protective cover 2 by means of a card connection (a card block and a card slot cooperate with each other), thereby increasing the connection stability between the baffle 7 and the protective cover 2 without interfering with the normal rotation of the baffle 7.

[0044] According to some embodiments of the present application, the protective cover 2 is optionally made of plastic material, and the plastic material may be PET, PS, PP, PVC, etc. The protective cover 2 made of plastic material has the advantages of light weight and low cost. Under the premise of ensuring the most important protective function of the protective cover 2, the production cost is reduced, and the weight of the entire cable is reduced.

[0045] In addition, the outer surface of the protective cover 2 is fixedly connected with friction lines (not shown in the figure). When adjusting the position of the protective cover 2, the staff needs to contact the protective cover 2. The friction lines can increase the friction between the hand and the protective cover 2, so as to better apply force to the protective cover 2.

[0046] The implementation principle of a connecting cable in an embodiment of the present application is as follows: the connector 12 of the cable body 1 is used to connect to the intercom. When the connector 12 is not connected to the intercom, the staff can apply a rotational external force to the sliding sleeve 4, so that the protective cover 2 moves on the wire 11 along with the sliding sleeve 4. At this time, the protective cover 2 gradually approaches the connector 12 until the connector 12 is located in the accommodating cavity 3, thereby shielding and protecting the connector 12, reducing the influence of external substances (such as moisture and dust) on the cable, and facilitating the protection of the cable.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
