Description

Technical Field

[0001] The present invention belongs to the technical field of cables, and in particular relates to a bundled cable connection device and a bundled cable. Background Art

[0002] A bundled cable is a system of multiple wires or cables assembled together in a specific manner to form a single cable bundle. Correspondingly, the connectors for bundled cables are also multi-channel connectors. Existing connectors for bundled cables typically utilize a multi-pin, socket-type structure. This structure is prone to loose contact after repeated plugging and unplugging. Once loose contact occurs, it directly affects the connector's transmission performance, requiring prompt replacement of the connector. However, replacing connectors is often cumbersome in practice, leading to the urgent need to address the issue of extending the service life of bundled cable connectors. Summary of the Invention

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention 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 only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] Example 1, the present invention provides a bundled cable connection device, see Figures 1-6 , including a plug 10 and a socket 20, the plug is equipped with a plurality of pins 30, and the socket is equipped with a sleeve 40 at the position corresponding to the pins, the pin includes a connecting portion 30-1, a first plug-in portion 30-2 and a second plug-in portion 30-3, the first plug-in portion and the second plug-in portion can both be inserted into the sleeve; the first plug-in portion and the second plug-in portion can be detachably connected to the connecting portion at the same time, and after connection, the first plug-in portion and the second plug-in portion are located in a straight line; the first plug-in portion and the second plug-in portion can be selectively detachably connected to the plug-in portion; in this embodiment, a threaded column 3 is provided on the connecting portion 0-11, the first plug-in portion is sleeved on the threaded column and is threadedly connected to the threaded column; one end of the second plug-in portion is threadedly connected to the threaded column; a first cutting groove 30-31 and a second cutting groove 30-32 are provided on the second plug-in portion, one end of the first cutting groove extends to the end where the threaded column is connected to the second plug-in portion, and the other end is arranged close to the second cutting groove to form a shorter connecting portion, and the second cutting groove is arranged close to the end of the second plug-in portion away from the first plug-in portion; a threaded hole 30-33 for connecting to the threaded column is provided at the center position within the second plug-in portion.

[0018] When the above-mentioned bundled cable connection device is in use, the multiple wires of the bundled cable are connected one by one to the multiple pins. The socket of the socket can be connected to multiple channels of the circuit board or to another bundled cable. This is well known to those skilled in the art and will not be described in detail here. When the plug and the socket are connected, the second plug part is first inserted into the plug tube for use. When the contact becomes loose after plugging and unplugging several times, the second plug part can be removed and the first plug part can be used to continue to connect with the plug tube. When the contact becomes loose after plugging and unplugging the first plug part several times, the second plug part can be replaced to replace the first plug part. Since the contact position between the plug part and the plug tube is changed each time, the contact position between the plug part and the plug tube is changed. Figure 5 The bottom end of the second connector (the bottom end) first contacts the insert and rubs against it throughout the entire plugging process. The removal process is the opposite of the insertion process, and the point where the insert initially contacts the insert experiences the most wear during the insertion and removal process. Consequently, the shorter connection portion is subject to wear, and when the second connector is installed on the threaded post, the shorter connection portion is easily squeezed and damaged, causing the first and second cutting grooves to form a single cutting groove. Under the squeezing action of the threaded post, the second connector on either side of the cutting groove opens slightly outward, allowing it to be reused several times. In this case, the cable connector can be prepared in advance for replacement, or the first or second connector can be purchased in advance for repair. This shows that the bundled cable connector of this embodiment significantly improves the service life of the bundled cable connector compared to existing structures.

[0019] As a preferred embodiment, see Figure 1 and Figure 2 , the plug is provided with a first protective cover 10-1 and a second protective cover 10-2, both of which are located on the outside of the pin, and the first protective cover is provided corresponding to the first plug-in part; the second protective cover is provided corresponding to the second plug-in part; fixing parts 10-3 are provided on both sides of the second protective cover, and the fixing parts are detachably connected to the plug; the positions of the socket corresponding to the first protective cover and the second protective cover are provided with plug-in slots 20-1 for inserting the second protective cover and the first protective cover, and the plug is located in the plug-in slot; the second protective cover and the first protective cover can be selectively inserted into the plug-in slot, wherein the first protective cover and the second protective cover can both be metal protective covers, such as protective covers made of copper or stainless steel. When this structure is in use, the second protective cover is first inserted into the plug-in slot to protect the pin; when the second plug-in part is removed and the first plug-in part is used to continue to be connected to the plug, the second protective cover is removed and the first protective cover is used as protection for the pin.

[0020] During actual production, it is best to set a chamfer on the front end of the second plug-in part (corresponding to the bottom end in the figure) to facilitate the second plug-in part to enter the plug-in tube at the beginning. Of course, it is best to also set a corresponding chamfer on the first plug-in part. Among them, since the threaded column is exposed outside the first plug-in part, it is also convenient for the pin to be plugged into the corresponding plug-in tube.

[0021] During actual production, a fixing hole 10-31 can be provided on the fixing part, and the fixing hole is a countersunk hole. A first threaded hole 10-4 is provided on the plug at a position corresponding to the fixing hole. During installation, the corresponding bolt is passed through the fixing hole to connect with the first threaded hole.

[0022] In actual production, the end of the insert facing away from the pin is connected to a terminal 40-1; the terminal extends out of the side of the socket facing away from the plug; and the pin extends out of the side of the plug facing away from the socket to facilitate wiring or connecting to solder pads. The terminal and insert can be integral or detachably connected, such as by fitting the insert onto the connector and threading it.

[0023] As a preferred embodiment, the plug is provided with a second threaded hole 10-5, and the socket is provided with a third threaded hole 20-2 corresponding to the second threaded hole. During use, the plug and socket can be connected by bolts connecting the second and third threaded holes. This secures the plug and socket after the pin and the socket are connected, effectively protecting the connection between the pin and the socket.

[0024] Example 2: Example 2 is a bundled cable. In the above-mentioned bundled cable connecting device, the bundled cable can be connected to a plug or a socket, and no specific limitation is made here.
