Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a C-type connector. Background Technology

[0002] The connecting cable is mainly used for electrical connection between two devices. Both devices are usually equipped with sockets. When using it, one end of the connecting cable is inserted into the socket of one device, and the other end of the connecting cable is inserted into the socket of the other device.

[0003] There are many types of connecting cables on the market. Classified by function, they can be divided into data cables, audio cables, power cables, video cables, etc. When connecting two devices, both audio and power cables are typically connected separately to the two devices. This means each device needs an audio jack for the audio cable and a power jack for the power cable. However, in environments requiring two cables, problems such as messy wiring, tangled cables, and an excessive number of ports on the devices can arise. Therefore, existing connecting cables are often limited in function, have poor applicability, and are inconvenient to use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a C-type connecting cable, which improves the structure of the connecting cable so that the connecting cable has two functions at the same time, thus solving the problem of inconvenience in previous use.

[0005] To solve the above-mentioned technical problems, this utility model discloses a C-type connector, including an outer sheath, a first conductor, a second conductor, and two connectors. The first conductor has a first core and a first inner sheath covering the outer periphery of the first core. The second conductor has a second core and a second inner sheath covering the outer periphery of the second core. Each connector has a first through hole arranged along its axial direction, and each connector has a welding groove on its outer peripheral side. The groove wall of the welding groove has a second through hole communicating with the bottom surface of the connector. One end of the first conductor passes through the first through hole of one connector, and the other end of the first conductor passes through the first through hole of the other connector. One end of the second conductor passes through the second through hole of one connector, and the other end of the second conductor passes through the second through hole of the other connector. The cores of each second conductor are welded in the welding groove. The outer sheath covers the outer periphery of the connector, the first conductor, and the second conductor. The connector is made of metal.

[0006] The connector is a columnar structure.

[0007] The connector has at least one retaining portion extending outward from its outer peripheral side, and the retaining portion is located at the top of the connector.

[0008] The connector is made of copper.

[0009] The connector also has a groove arranged around its circumference, which is located above the welding groove.

[0010] The connector has at least one locking protrusion protruding outwards from its outer peripheral side, and the locking protrusion is located on the side of the welding groove.

[0011] The first inner sheath of the first conductor passes through the first through hole.

[0012] Compared with the prior art, the present invention has the following advantages: by setting a connector, the first wire is insulated from the connector and passes through the end of the connector, and the second wire is electrically connected to the connector, so that the ends of the connector form two independent connector terminals, which can be electrically connected to the connector hole with two connector terminals, so that the signal can be transmitted and the power can be supplied at the same time. The electronic device does not need to set two sockets, which solves the problem of inconvenience in the past. The overall structure is simple and compact, and has the functions of both power line and signal line. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model discloses a specific embodiment of a C-type connector cable, please see... Figures 1 to 3 The connecting wire includes an outer sheath 1, a first conductor 21, a second conductor 22, and two connectors 3. It should be noted that the outer sheath 1 is C-shaped, and the two connectors 3 are fixedly installed at the front and rear ends of the outer sheath 1, respectively. The first conductor 21 and the second conductor 22 are both embedded inside the outer sheath 1, located between the two connectors 3, and both are C-shaped. The first conductor 21 and the second conductor 22 are respectively connected to their corresponding connectors 3.

[0021] In this embodiment, the first conductor 21 is provided with a first core (not shown) and a first inner sheath covering the outer periphery of the first core, and the second conductor 22 is provided with a second core (not shown) and a second inner sheath covering the outer periphery of the second core. It should be noted that the first core and the second core can be conductive metal wires or metal strips, or enameled wires, etc. The first conductor 21 and the second conductor 22 can be understood as enameled wires or cables.

[0022] As an improvement, each connector 3 is provided with a first through hole 31 arranged along its axial direction, and a welding groove 33 is provided on the outer peripheral side of each connector 3. The groove wall of the welding groove 33 is provided with a second through hole 32 that communicates with the bottom surface of the connector 3. The connector 3 is a metal structure.

[0023] During the assembly of the connecting wires in this embodiment, one end of the first conductor 21 passes through the first through hole 31 of one of the connectors 3, and the other end of the first conductor 21 passes through the first through hole 31 of another connector 3, so that the first inner sheath of the first conductor 21 passes through the first through hole 31. In this way, a barrier layer (first inner sheath) is provided between the first core of the first conductor 21 and the connector 3, thereby ensuring that the first core is insulated from the connector 3. One end of the second conductor 22 passes through the second through hole 32 of one of the connectors 3, and the other end of the second conductor 22 passes through the second through hole 32 of another connector 3. The cores of each second conductor 22 are soldered in the soldering groove 33. It can be understood that the end of the second core of the second conductor 22 protrudes from the second sheath. The second core is soldered to the soldering groove 33 of the connector 3 by soldering, thereby realizing the electrical connection between the second conductor 22 and the connector 3. The connector 3 itself can act as a first connecting terminal, and the first core of the first conductor 21 can act as a second connecting terminal. The end of the first core of the first conductor 21 can be externally connected to other connecting accessories.

[0024] In this embodiment, the outer sheath 1 covers the outer periphery of the connector 3, the first wire 21, and the second wire 22. Specifically, the outer sheath 1 can be formed on the outer periphery of the three by injection molding. It mainly serves to protect and fix the connector, which can extend the service life of the connector and avoid problems such as tangling and mess.

[0025] In this embodiment, the connector 3 is made of metal, preferably copper. In other embodiments, the connector 3 can be made of aluminum. Furthermore, the connector 3 has a columnar structure, which facilitates mass production and assembly.

[0026] To facilitate the connection between the connector 3 and the socket of an external device, two retaining portions 34 extend outward from the outer periphery of the connector 3. Both retaining portions 34 are petal-shaped and are arranged symmetrically around each other, with the retaining portions 34 located at the top of the connector 3.

[0027] To enhance the connection strength between the outer sheath 1 and the connector 3, the connector 3 is also provided with a groove 35 arranged circumferentially around the connector 3. The groove 35 is located above the welding groove 33. In addition, at least one retaining protrusion 36 protrudes outward from the outer peripheral side of the connector 3, and the retaining protrusion 36 is located to the side of the welding groove 33. The functions of the groove 35 and the retaining protrusion 36 are both to enhance the connection strength between the outer sheath 1 and the connector 3, preventing the outer sheath 1 and the connector 3 from separating too easily and improving their service life.

[0028] In this embodiment, the C-type connector cable has a connector 3. The first conductor 21 is insulated from the connector 3 and extends out of the end of the connector 3. The second conductor 22 is electrically connected to the connector 3, so that the ends of the connector cable form two independent connector terminals. This allows for electrical connection with connector holes that have two connector terminals, enabling signal transmission and power supply at the same time. Electronic devices do not need to have two connectors, solving the inconvenience problem of previous use. The overall structure is simple and compact, and it has both power and signal cable functions.

[0029] Finally, it should be noted that the C-type connecting cable disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
