Referring to fig. 1 to 3, the present invention provides an electrical connector 100, which is mainly used for being mounted on a battery, so that two or more batteries can be quickly electrically connected through the electrical connector 100.

In the embodiment of the present invention, the electrical connector 100 includes a first connector 1 and a second connector 2 connected to the first connector 1 in a plugging manner, the first connector 1 includes a first base 11, a socket 12 and a first safety seat 13 electrically connected between the first base 11 and the socket 12, the second connector 2 includes a second base 21, a plug 22 connected to the socket 12 in a plugging manner, and a second safety seat 23 electrically connected between the second base 21 and the plug 22; an end face of the socket 12, which is far away from the first safety seat 13, is concavely provided with a jack 121, the inner wall of the jack 121 is provided with at least one limiting groove 122 and a plurality of first elastic sheets 123, one end of the plug 22, which is far away from the second safety seat 23, is provided with a guide post 221 for abutting against the first elastic sheets 123 and a guide sleeve 222 surrounding the guide post 221 and used for being in plug-in fit with the jack 121, and the guide sleeve 222 is provided with second elastic sheets 223 which are in one-to-one clamping connection with the limiting grooves 122; after the guide sleeve 222 is inserted into the insertion hole 121, the guide post 221 is pressed against the first elastic sheet 123, and one end of the second elastic sheet 223 close to the second safety seat 23 is clamped in the limiting groove 122.

In an embodiment, referring to fig. 4, when the electrical connector 100 is used, the first connector 1 and the second connector 2 are respectively welded to the positive electrode and the negative electrode of the battery 200, so that when each battery 200 needs to be electrically connected to another battery 200, only the plug 22 of the second connector 2 of one of the batteries 200 needs to be inserted into the socket 12 of the first connector 1 of another battery 200, the electrical connection process is simple and convenient, and meanwhile, the plug 22 and the socket 12 are more stably and reliably electrically connected through the clamping fit of the second elastic piece 223 and the limiting groove 122 and the abutting fit of the guide post 221 and the first elastic piece 123.

Furthermore, the guide sleeve 222 is provided with a plurality of limiting windows 2221, each second elastic piece 223 extends from the inner wall of one limiting window 2221 to form, and one end of each second elastic piece 223 close to the first safety seat 13 tilts towards the direction away from the guide post 221, it can be understood that, after the guide sleeve 222 is inserted into the insertion hole 121, when the second elastic piece 223 moves to the position where the limiting groove 122 is arranged, one end of the second elastic piece 223 close to the first safety seat 13 can bounce into the limiting groove 122, so that the plug 22 and the socket 12 can automatically form self-locking, the installation process is simpler, and the assembly time can be effectively reduced.

In this embodiment, in order to facilitate the installation of the second elastic piece 223 and the limiting groove 122 to form a clamping connection, the inner wall of the insertion hole 121 is further provided with a guide groove 124 communicated with the limiting groove 122, and the guide groove 124 opens one end of the socket 12 away from the first safety seat 13, so that the guide groove 124 can play a role in positioning, and thus when the guide sleeve 222 is inserted into the insertion hole 121, the second elastic piece 223 can be relatively quickly aligned to the limiting groove 122, and meanwhile, the second elastic piece 223 cannot shift in the process of being inserted into the insertion hole 121 along with the guide sleeve 222 through the guide groove 124.

Further, first shell fragment 123 and the bottom interval parallel arrangement of jack 121 for first shell fragment 123 has the space that produces elastic deformation to the bottom that is close to spacing groove 122, and guide pillar 221 supports and presses behind first shell fragment 123 promptly, and first shell fragment 123 can produce certain deformation, makes guide pillar 221 push the inner wall of second shell fragment 223 butt spacing groove 122 on the guide pin bushing 222 under the elastic action of first shell fragment 123, can effectively improve the stability of electricity connection. In this embodiment, the first elastic pieces 123 are uniformly distributed along the central axis of the insertion hole 121, so that the stress on the portion of the guide post 221 abutting against the first elastic pieces 123 is more uniform, and the stability of electrical connection is further improved.

Further, the length of the guide sleeve 222 is smaller than that of the guide post 221, that is, one end of the guide sleeve 222 abutting against the first elastic piece 123 extends out of the guide sleeve 222, so that after the guide sleeve 222 abuts against the first elastic piece 123, the guide sleeve 222 and the first elastic piece 123 are still spaced, and the problem of poor contact between the guide post 221 and the first elastic piece 123 caused by the fact that the guide sleeve 222 abuts against the first elastic piece 123 can be prevented.

Furthermore, in order to facilitate the plug 22 to be pulled out of the socket 12, two sides of the second elastic piece 223 are respectively provided with a guide surface 2231, and the guide surfaces 2231 are arc-shaped, when the plug 22 needs to be pulled out of the socket 12, the plug 22 is rotated so that the second elastic piece 223 can be moved out of the corresponding limiting groove 122 through the guide surfaces 2231, and at this time, the plug 22 can be pulled out of the socket 12 by force.

In the present embodiment, in order to facilitate the rotation of the plug 22, the first base 11 and the second base 21 have the same shape and size, and both have the hexagonal prism shape, that is, the first base 11 and the second base 21 serve as the force-receiving portion of the rotation plug 22, and the hexagonal prism shape is also used for facilitating the use of a wrench tool.

In the embodiment of the present invention, the first safety seat 13 and the second safety seat 23 both play a role of circuit breaking protection when the battery is abnormal, so as to prevent the abnormal battery from generating fire safety hazard due to large current, specifically, the structure of the first safety seat 13 and the second safety seat 23 is completely consistent and includes the fuse 131 and the insulating shell 132 surrounding the fuse 131, the fuse 131 is used for electrically connecting the first base 11 and the socket 12 or electrically connecting the second base 21 and the plug 22, and the insulating shell 132 is used for connecting the first base 11 and the socket 12 or the second base 21 and the plug 22.

In the present embodiment, the first annular groove 111 for connecting the insulating shell 132 is opened at one end of the first base 11 close to the socket 12, and the second annular groove 211 for connecting the insulating shell 132 is opened at one end of the second base 21 close to the plug 22.
