These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the position of these elements changes, the indication of these directions changes accordingly.
Preferred embodiments of the present utility model will be further elaborated below in conjunction with the drawings of the present specification.
Referring to fig. 1 to 4, the electrical connector assembly 100 of the present preferred embodiment includes a first electrical connector 1 and a second electrical connector 2 mated with each other. The first electrical connector 1 is preferably adapted to be mounted on a cable end and the second electrical connector 2 is preferably adapted to be mounted on an equipment end. The first electrical connector 1 and the second electrical connector 2 are mated in the front-rear direction, and for convenience of description, the direction of one end of the two mated ends is defined as "front", and the opposite direction is defined as "rear".
Referring to fig. 4 to 8, the first electrical connector 1 includes an insulating base 11, a magnet 12 fixed in the insulating base 11, a plurality of first conductive terminals 13 fixed on the insulating base 11 in two rows, and a first housing 14 sleeved on the outer periphery of the insulating base 11.
The insulating holder 11 is made of an insulating material and is preferably bonded to the plurality of first conductive terminals 13 by insert molding.
The insulating base 11 includes a base body 111 and a tongue plate 112 protruding forward from the base body 111. As shown in fig. 7 and 8, the base 111 has a hollow block-shaped structure with a racetrack shape, and the tongue plate 112 has a hollow rectangular block-shaped structure. The base 111 is communicated with the cavity inside the tongue plate 112 to form a receiving groove 114 concavely arranged from the rear end surface of the base 111. The front end face 1121 of the tongue plate 112 is closed and is blocked in front of the accommodation groove 114. The upper and lower sides of the tongue plate 112 are in the shape of a fence, and the hollow part of the fence is communicated with the accommodating groove 114.
Referring to fig. 4, 5 and 7, the magnet 12 has a rectangular block shape, and is preferably inserted and fixed into the receiving groove 114 of the insulating base 11 from the rear, the rear end surface of the magnet 12 is substantially flush with the rear end surface of the insulating base 11, and the front end of the magnet 12 is shielded by the front end surface 1121 of the tongue plate 112, so as to facilitate reducing contamination by substances having ferromagnetism from the outside. The magnet 12 is preferably a neodymium iron boron magnet, and an insulating layer (such as epoxy) may be added to the surface of the magnet to prevent electrical conduction with the first conductive terminal 13. The upper and lower sides of the magnet 12 with the largest area are the magnetic pole surfaces, i.e., the upper and lower sides are the N-pole surface 121 and the S-pole surface 122, respectively, and the two magnetic pole surfaces 121, 122 face the upper and lower sides of the tongue plate 112, respectively.
Since the magnetic flux Φ=bs of the magnet 12, the magnetic pole of the magnet 12 is arranged in such a manner that the upper and lower side surfaces having the largest surface area S are used as the two magnetic pole surfaces 121, 122, so that the magnet 12 can obtain the largest magnetic flux when using the same ferromagnetic substance, thereby being advantageous in enhancing the attraction magnetic force thereof.
Referring to fig. 4 to 8, the plurality of first conductive terminals 13 are distributed in two rows in the insulating base 11 at intervals, and the two rows of first conductive terminals 13 are preferably arranged on the tongue plate 112 in 180-degree rotation symmetry to support 180-degree rotation bidirectional butt joint. Two rows of first conductive terminals 13 are respectively filled in the fence hollows at the upper and lower sides of the tongue plate 112 so as to be exposed at the outer surfaces of the upper and lower sides of the tongue plate 112, and the two rows of first conductive terminals 13 are respectively closely attached to the N pole face 121 and the S pole face 122 of the magnet 12.
In the preferred embodiment, the first conductive terminal 13 is made of a conductive material with magnetic permeability, and such material may be ferrite stainless steel or martensitic stainless steel, for example, SUS430 stainless steel, which can be electrically connected and can also conduct magnetic force lines.

Wherein, the connecting portion 132 is embedded in the base 111. The contact portion 131 protrudes forward from the connection portion 132 and is exposed at the upper and lower sides of the tongue plate 112 for electrical connection with the second electrical connector 2. The welding portion 133 protrudes rearward from the base 111 for welding to a cable (not shown). One side of the contact portion 131 of the first conductive terminal 13 is exposed to the surface of the tongue plate 112, and the opposite side is correspondingly attached to one of the magnetic pole faces 121, 122 of the magnet 12.
Preferably, the front end of the contact portion 131 is embedded in the tongue plate 112, but does not exceed the front end face 1121 of the tongue plate 112, so that the tongue plate 112 forms a front stop position for the first conductive terminal 13. The front end of the contact portion 131 further extends forward beyond the magnet 12, so that when the contact portion is mated with the second electrical connector 2, the front end of the contact portion 131 extends deeper into the second electrical connector 2 than the magnet 12, so as to better conduct the magnetic force lines emitted from the magnet 12 forward, thereby increasing the magnetic attraction between the first electrical connector 1 and the second electrical connector 2.

The first housing 14 is preferably made of metal material, and is sleeved on the outer periphery of the insulating base 11, so as to play a role in signal shielding and reduce electromagnetic interference.

Referring to fig. 9 and 10, the second conductive terminal module 230 includes a fixing element 26 and a plurality of second conductive terminals 23 arranged side by side on the fixing element 26. Wherein the fixing element 26 and the plurality of second conductive terminals 23 are preferably bonded together by an insert molding process.

The second conductive terminals 23 in each second conductive terminal module 230 respectively correspond to the openings 212, and the abutting portions 231 of the second conductive terminals 23 protrude into the cavity 211 through the openings 212. The tail portion 233 of each second conductive terminal 23 extends rearward out of the base 21 for electrical connection with a circuit board (not shown) of the electronic device.
Specifically, the first extension 2311 of the docking portion 231 extends obliquely forward and toward the inside of the cavity 211, and the second extension 2312 extends obliquely forward away from the cavity 211.
