Detailed Description

The specific embodiments illustrated below are intended as descriptions of various configurations of the subject technology and are not intended to represent the only configurations in which the subject technology may be practiced. Particular embodiments include specific details for the purpose of providing a thorough understanding of the subject technology. It will be clear and apparent, however, to one skilled in the art that the subject technology is not limited to the specific details shown herein and may be practiced without these specific details.

Referring to fig. 1 to 6, a separable multi-core electrical connector comprises a plug 1 and a socket 2 matched with the plug 1, wherein the plug 1 is provided with a pin 11, and the socket 2 is provided with a jack 21 matched with the pin 11;

an elastic piece 31 for pushing the plug 1 to be separated from the socket 2 is arranged between the plug 1 and the socket 2;

a fixing mechanism 3 for fixing the plug 1 to the socket 2 is further arranged between the plug 1 and the socket 2, the fixing mechanism 3 comprises a screw 32 arranged on the plug 1, and the fixing mechanism 3 further comprises a screw hole 33 arranged on the socket 2 and matched with the screw 32;

at least two screws 32 are provided, the screws 32 are uniformly arranged on the plug 1, and the fixing mechanism 3 further comprises a transmission mechanism 34 for driving all the screws 32 to rotate simultaneously.

The pin 11 is usually a contact such as a twist pin, so that in order to make the connector capable of providing more pins 11, the pins 11 usually have a smaller diameter, and in a practical process, when the pins 11 are mated with or separated from the sockets 21, the pins 11 are easily bent and damaged due to possible dislocation between the plug 1 and the socket 2.

In this embodiment, by setting the transmission mechanism 34, all the screws 32 disposed on the plug 1 can rotate simultaneously under the drive of the transmission mechanism 34, and all the screws 32 adopt the same pitch, so that all the screws 32 move simultaneously, and further the plug 1 is displaced in a linear direction and cannot incline, the contact pin 11 has higher position accuracy relative to the jack 21, and the contact pin 11 is not easy to bend when the plug 1 is matched with or disassembled from the socket 2.

Meanwhile, by arranging the transmission mechanism 34, the transmission mechanism 34 is matched with all the screws 32, so that the anti-loosening function can be achieved, and the plug 1 and the socket 2 are not easy to loosen, so that the electric connector can be used under a worse working condition.

Taking an electrical connector with 660 cores and a pitch of 0.06mm as an example, 660 cores represent that the plug 1 is provided with 660 pins 11, and when the pins 11 are assembled with or separated from the insertion holes 21, a large force needs to be applied to enable the plug 1 to be matched with or separated from the pins 11.

Meanwhile, since the socket 2 and the header 1 are fixed by the screws 32, misalignment of the pins 11 with respect to the insertion holes 21 may be caused when the two screws 32 are not rotated at the same time, thereby causing bending of the pins 11. The transmission mechanism 34 is adopted to drive the two screws 32 to rotate simultaneously, so that the contact pin 11 and the jack 21 have higher position accuracy, and the contact pin 11 is not easy to bend.

Referring to fig. 1 to 6, in some embodiments, the transmission mechanism 34 includes a rotating shaft 341 rotatably disposed on the plug 1, the rotating shaft 341 is provided with a number of worms 342 equal to the number of screws 32, each screw 32 is provided with a worm wheel 343 engaged with the worm 342, and each worm wheel 343 is engaged with a separate worm 342.

The worm gear 343 may be of unitary construction with the screw 32. When the plug 1 and the socket 2 are assembled, the rotating shaft 341 can be rotated by a tool, all the worms 342 rotate in the rotating process of the rotating shaft 341, the worms 342 rotate to drive all the screws 32 to rotate simultaneously, and after all the screws 32 are screwed, the plug 1 and the socket 2 are matched. At this time, the elastic member 31 is compressed, and the elastic member 31 can function as a locking function for the screw 32.

Meanwhile, because the matching between the worm wheel 343 and the worm 342 has a self-locking property, the worm wheel 343 cannot drive the worm 342 to rotate, and therefore, the transmission mechanism 34 also has a locking effect on the screw 32. The plug 1 and the socket 2 are not easy to loosen.

When the plug 1 and the socket 2 need to be detached, all the screws 32 can be loosened by rotating the rotating shaft 341 in the opposite direction, and at this time, the elastic member 31 is restored to the original shape, the plug 1 is pushed away by the elastic member 31, and the plug 1 and the socket 2 are separated.

In some embodiments, the plug 1 is provided with a shaft hole in which the rotating shaft 341 is mounted, and a rolling bearing 35 is disposed between the rotating shaft 341 and the shaft hole.

The rolling bearing 35 is a radial thrust bearing, an inner ring of the rolling bearing 35 is in interference fit with the rotating shaft 341, and an outer ring of the rolling bearing 35 is in interference fit with the shaft hole.

The worm 342 is mounted on the rotating shaft 341 through a key connection.

The rotating shafts 341 may be in a split structure, and the shaft bodies of two adjacent sections of rotating shafts 341 may be connected by adopting a coupling, so that the rotating shafts 341, the worm 342 and the rolling bearing 35 are easy to assemble.

Referring to fig. 1 to 3, in some embodiments, the plug 1 includes a housing including an upper half 12 and a lower half 13, the pins 11 are disposed on the lower half 13, the upper half 12 and the lower half 13 are each provided with a groove forming the shaft hole, and the upper half 12 is fixed to the lower half 13 by threads. The upper half 12 may be fixed to the lower half 13 by screws.

The lower half 13 may be of unitary construction for mounting the pins 11 and other associated accessories. The upper half 12 is mainly used for installing the rotating shaft 341 in cooperation with the lower half 13. Therefore, when the rotation shaft 341 is installed by other structures, the upper half 12 may be omitted. For example, the shaft 341 may be directly fixed to the lower half 13 by lugs.

In some embodiments, the elastic member 31 is a spring, the spring is disposed between the jack 21 and the pin 11, one end of the elastic member 31 is fixed to the jack 21, and the other end of the elastic member 31 abuts against the pin 11.

In some embodiments, the elastic member 31 is a spring, the elastic member 31 is fixed to the plug 1, and the elastic member 31 is sleeved on the screw 32. The screw 32 guides the spring and extends its service life.

The plug 1 is provided with a receiving groove for receiving the elastic member 31, and a portion of the elastic member 31 is located in the receiving groove. By providing the accommodating groove, when the elastic member 31 is compressed, the elastic member 31 can be positioned in the accommodating groove, so that the plug 1 and the socket 2 can be in direct contact, and dust is prevented from entering between the plug 1 and the socket 2.

In some embodiments, the plug 1 is provided with a guide ring 111, the guide ring 111 protrudes out of the plug 1, all the pins 11 are located in a space surrounded by the guide ring 111, and the socket 2 is provided with a guide groove 22 matched with the guide ring 111.

The guide ring 111 may be made of a metal material, and the guide ring 111 may be made of a non-metal material. The guide ring 111 mainly plays a guide function, so that the plug 1 has higher position accuracy relative to the socket 2, and thus the pin 11 has higher position accuracy relative to the jack 21, and the pin 11 is not easy to bend.

While the foregoing has been presented with a specific embodiment of the subject matter and with corresponding details, it should be understood that the foregoing description is only a few embodiments of the subject matter and that some details may be omitted when the embodiments are particularly implemented.
