Description

Technical Field

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

[0002] Bundled cables consist of 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 employ a multi-pin and socket structure. This structure is prone to loosening after several insertions and removals. Once loosening occurs, it directly affects the connector's transmission performance, necessitating timely replacement of the connection device. However, in practical use, replacing the connection device is quite cumbersome. Therefore, how to improve the service life of bundled cable connection devices has become an urgent technical problem to be solved. Summary of the Invention

[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 above-mentioned objectives, the present invention provides the following technical solution:

[0005] A bundled cable connection device includes a plug and a socket. The plug is equipped with a plurality of pins, and the socket is equipped with a socket corresponding to the position of the pins. Each pin includes a connecting part, a first plug-in part, and a second plug-in part. Both the first plug-in part and the second plug-in part can be inserted into the socket. The first plug-in part and the second plug-in part can be detachably connected to the connecting part simultaneously. After connection, the first plug-in part and the second plug-in part are aligned in a straight line. The first plug-in part and the second plug-in part can be selectively detachably connected to the connecting part.

[0006] Preferably, the connecting part is provided with a threaded post, the first insertion part is sleeved on the threaded post and threadedly connected to the threaded post; one end of the second insertion part is threadedly connected to the threaded post.

[0007] Preferably, the second insertion part is provided with a first cutting groove and a second cutting groove. One end of the first cutting groove extends to the end where the threaded post connects to the second insertion part, and the other end is located near the second cutting groove. The end of the second cutting groove is located near the second insertion part and away from the first insertion part. A threaded hole for connecting with the threaded post is provided at the center position of the second insertion part.

[0008] Preferably, the plug is provided with a first protective sleeve and a second protective sleeve, both of which are located outside the pins. The first protective sleeve is provided corresponding to the first insertion part; the second protective sleeve is provided corresponding to the second insertion part; fixing parts are provided on both sides of the second protective sleeve, and the fixing parts are detachably connected to the plug; the socket is provided with a insertion groove for inserting the second protective sleeve and the first protective sleeve at the positions corresponding to the first and second protective sleeves, and the plug is located in the insertion groove; the second protective sleeve and the first protective sleeve can be selectively inserted into the insertion groove.

[0009] Preferably, the first and second protective sleeves are metal protective sleeves.

[0010] Preferably, the fixing part is provided with a fixing hole, the fixing hole is a countersunk hole, and the plug is provided with a first threaded hole at the position corresponding to the fixing hole.

[0011] Preferably, the end of the insert opposite to the pin is connected to a terminal block.

[0012] Preferably, the terminal extends out of the socket on the side opposite to the plug; the pin extends out of the plug on the side opposite to the socket.

[0013] Preferably, the plug is provided with a second threaded hole, and the socket is provided with a third threaded hole corresponding to the second threaded hole.

[0014] When using the bundled cable connection device provided by the present invention, the second plug is first inserted into the socket when the plug and socket are connected. When the contact becomes loose after several insertions and removals, the second plug can be removed and the first plug can be used to continue connecting to the socket. This greatly improves the service life of the bundled cable connection device compared to the existing structure.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0029] Example 1: The present invention provides a bundled cable connection device, see [link to example]. Figures 1-6The device includes a plug 10 and a socket 20. The plug has multiple pins 30 installed on it, and the socket has a socket 40 corresponding to the pin positions. Each pin includes a connecting part 30-1, a first insertion part 30-2, and a second insertion part 30-3. Both the first and second insertion parts can be inserted into the socket. The first and second insertion parts can be detachably connected to the connecting part simultaneously, and after connection, the first and second insertion parts are aligned in a straight line. Either the first or second insertion part can be detachably connected to the connecting part. In this embodiment, the connecting part is provided with a threaded post 3. 0-11, the first insertion part is sleeved on the threaded post and threadedly connected to the threaded post; one end of the second insertion part is threadedly connected to the threaded post; the second insertion part is provided with a first cutting groove 30-31 and a second cutting groove 30-32, one end of the first cutting groove extends to the end of the threaded post connected to the second insertion part, and the other end is set close to the second cutting groove to form a shorter connection part, and the end of the second cutting groove is set close to the second insertion part and away from the first insertion part; a threaded hole 30-33 for connecting with the threaded post is provided at the center position of the second insertion part.

[0030] 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 here. When connecting the plug and socket, the second connector is first inserted into the insert. If the contact becomes loose after several insertions and removals, the second connector can be removed, and the first connector can continue to connect to the insert. If the contact becomes loose after several insertions and removals, the second connector can be used to replace the first connector. Since the initial contact position between the connector and the insert is determined each time it is plugged in (…), the connection is determined by the number of pins. Figure 5 The bottom end of the connector first contacts the insert and rubs against it throughout the insertion process. The removal process is the opposite of the insertion process, and the initial contact point of the insert experiences the greatest wear during insertion and removal. Therefore, the shorter connecting portion is worn, and when the second connector is installed onto the threaded post, it is easily damaged, causing the first and second cutting grooves to form a single cutting groove. Under the squeezing action of the threaded post, the portions of the second connector on both sides of the cutting groove slightly open outwards, allowing it to be reused several times. Of course, in this case, the cable connection device can be replaced in advance, or the first or second connector can be purchased in advance for repair. Thus, it can be seen that the bundled cable connection device in this embodiment significantly improves the service life of the bundled cable connection device compared to existing structures.

[0031] As a preferred implementation method, see [link to relevant documentation]. Figure 1 and Figure 2The plug is provided with a first protective sleeve 10-1 and a second protective sleeve 10-2, both of which are located outside the pins. The first protective sleeve corresponds to the first plug-in portion, and the second protective sleeve corresponds to the second plug-in portion. Fixing portions 10-3 are provided on both sides of the second protective sleeve, and these fixing portions are detachably connected to the plug. The socket is provided with a plug-in groove 20-1 for inserting the second and first protective sleeves, corresponding to their positions. The plug is located within the plug-in groove. Either the second or first protective sleeve can be inserted into the plug-in groove. Both the first and second protective sleeves can be metal, such as those made of copper or stainless steel. In use, the second protective sleeve is first inserted into the plug-in groove to protect the pins. When the second plug-in portion is removed and the first plug-in portion is used to continue connecting to the plug, the second protective sleeve is removed, and the first protective sleeve is used to protect the pins.

[0032] In actual manufacturing, it is best to set a chamfer at the front end of the second plug part (the corresponding bottom end in the figure) so that the second plug part can enter the plug tube at the beginning. Of course, it is also best to set a chamfer for the first plug part. Since the threaded post is exposed outside the first plug part, it is also convenient for the plug to be inserted into the plug tube.

[0033] In actual manufacturing, the fixing part can be provided with fixing holes 10-31, which are countersunk holes. The plug is provided with a first threaded hole 10-4 corresponding to the fixing hole. During installation, the corresponding bolts can be passed through the fixing hole and connected to the first threaded hole.

[0034] In actual manufacturing, the end of the socket facing away from the pin is connected to a terminal 40-1; the terminal extends out of the socket facing away from the plug; the pin extends out of the plug facing away from the socket, to facilitate wiring or connecting solder pads, etc. The terminal and the socket can be integrated, or they can be detachably connected, for example, by fitting the socket onto the connector and using a threaded connection.

[0035] In 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. In use, the plug and socket can be connected by bolts connecting the second and third threaded holes, thereby fixing the plug and socket after the pins and socket are connected, effectively protecting the connection between the pins and socket.

[0036] Example 2 is a bundled cable. The bundled cable connection device described above can be connected to a plug or a socket, without any specific limitation.
