Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a bundled cable connection device. Background Technology

[0002] Bundled cables are multiple wires or cables joined together in a specific way to form a single cable bundle. Correspondingly, the connection devices for bundled cables are also multi-channel connection devices. Existing bundled cable connection devices typically use a multi-pin and socket structure. This structure is prone to wear and poor contact after several insertions and removals, which in turn affects the connector's transmission performance. When poor contact occurs, the connection device needs to be replaced promptly. However, in actual use, replacing the connection device is cumbersome and increases costs to some extent. Therefore, researchers have been continuously studying how to improve the service life of bundled cable connection devices. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides a bundled cable connection device to solve the above-mentioned technical problems.

[0004] To achieve the aforementioned objectives, this utility model provides the following technical solution: A bundled cable connection device includes a plug and a socket. The plug is equipped with multiple pins, and the socket is equipped with a socket sleeve corresponding to the positions of the pins. Each pin includes a first connecting portion and a first insertion portion, wherein the diameter of the end of the first insertion portion connected to the first connecting portion is larger than the diameter of the other end. The socket sleeve includes a second connecting portion and a second insertion portion, wherein the diameter of the end of the second insertion portion connected to the second connecting portion is smaller than the diameter of the other end, and the first insertion portion can be inserted into the second insertion portion. The second insertion portion is provided with multiple strip-shaped notches circumferentially, and the outer surface of the second insertion portion is provided with external threads corresponding to the positions of the strip-shaped notches. A nut is fitted on the second insertion portion, and the inner side of the nut is provided with an internal thread that mates with the external threads.

[0005] Preferably, the plug is provided with a protective cover, and the socket is provided with a plug groove for inserting the protective cover at the position corresponding to the position of the protective cover, and the plug is located in the plug groove.

[0006] Preferably, the protective sleeve is a metal protective sleeve.

[0007] Preferably, the second connecting portion extends out of the socket on the side opposite to the plug; the first connecting portion extends out of the plug on the side opposite to the socket.

[0008] Preferably, the plug is provided with a first threaded hole, and the socket is provided with a second threaded hole at the position corresponding to the first threaded hole.

[0009] When using the bundled cable connection device provided by this utility model, the first plug part is inserted into the second plug part when the plug and socket are connected. After several insertions and removals, if poor contact occurs due to wear, the nut can be rotated to make the nut press the second plug part inward and slightly deform it, reducing the size of the strip notch. This reduces the inner diameter of the second plug part, resulting in better contact between the first plug part and the second plug part after insertion, allowing for continued use. Therefore, the bundled cable connection device in this application improves the service life of the bundled cable connection device compared to existing structures. Attached Figure Description

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0012] In this embodiment, the present invention provides a bundled cable connection device, see [link to example]. Figures 1-5The device includes a plug 10 and a socket 20. The plug is equipped with multiple pins 30, and the socket is equipped with a socket sleeve 40 corresponding to the pin positions. Each pin includes a first connecting part 30-1 and a first insertion part 30-2. The diameter of the end of the first insertion part connected to the first connecting part is larger than the diameter of the other end, so that the first insertion part can be inserted into the second insertion part during use. The socket sleeve includes a second connecting part 40-1 and a second insertion part 40-2. The diameter of the end of the second insertion part connected to the second connecting part is smaller than the diameter of the other end. The second insertion part is provided with multiple strip-shaped notches 40-3 circumferentially. The outer surface of the second insertion part is provided with external threads 40-4 corresponding to the positions of the strip-shaped notches. A nut 40-5 is fitted on the second insertion part, and the inner side of the nut is provided with an internal thread that mates with the external threads.

[0013] In use, the aforementioned bundled cable connection device connects multiple wires of the bundled cable one-to-one with multiple pins. The socket's insert can connect to multiple channels of the circuit board or to another bundled cable, as is well known to those skilled in the art and will not be elaborated further here. When connecting the plug and socket, the first insertion part is inserted into the second insertion part. After several insertions and removals, if poor contact occurs due to wear, the nut can be rotated to slightly deform the second insertion part inward, reducing the notch size and thus decreasing the inner diameter of the second insertion part. This improves the contact between the first insertion part and the second insertion part, allowing for continued use. Therefore, the bundled cable connection device in this embodiment improves the service life of the bundled cable connection device compared to existing structures.

[0014] In the above embodiments, the shape of the nut is adapted to the shape of the second insertion part, that is, the diameter of one end near the second connection part is smaller than the diameter of the other end. In actual manufacturing, multiple fixing holes 40-6 or fixing grooves are preferably provided circumferentially on the end face of the nut away from the second connection part. When tightening the nut, a matching wrench can be inserted into the fixing hole or fixing groove at the corresponding part.

[0015] As a preferred implementation method, see [link to relevant documentation]. Figure 1 and Figure 2 The plug is provided with a protective sleeve 10-1, and the socket is provided with a plug groove 20-1 for inserting the protective sleeve at the position corresponding to the position of the protective sleeve. The plug is located in the plug groove, wherein the protective sleeve is a metal protective sleeve.

[0016] In actual manufacturing, the second connecting part extends out of the socket on the side opposite to the plug to facilitate wiring or connecting pads, etc.; the first connecting part extends out of the plug on the side opposite to the socket to facilitate wiring or connecting pads, etc. The second connecting part and the second plug can be integrally set or can be set in a detachable connection manner, such as by fitting the second plug onto the second connecting part and using a threaded connection.

[0017] In a preferred embodiment, the plug is provided with a first threaded hole 10-2, and the socket is provided with a second threaded hole 20-2 corresponding to the first threaded hole. In use, the plug and socket can be connected by bolts to the first and second threaded holes, thereby fixing the plug and socket after the pins and socket are connected, effectively protecting the connection between the pins and socket.
