Detailed Description

While this invention is susceptible of embodiment in different forms, there is shown in the drawings and will herein be described in detail, specific embodiments thereof with the understanding that the present description is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to that as illustrated.

Thus, a feature indicated in this specification is intended to describe one of the features of an embodiment of the invention and does not imply that every embodiment of the invention must have the described feature. Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.

In the embodiments shown in the drawings, directional references (such as upper, lower, left, right, front and rear) are used to explain the structure and movement of the various elements of the invention, rather than absolute, and relative. These descriptions are appropriate when the elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indication of these directions changes accordingly.

The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 4, the electrical connector assembly 100 of the preferred embodiment includes a first electrical connector 1 and a second electrical connector 2. The first electrical connector 1 is preferably adapted to be mounted at a cable end and the second electrical connector 2 is preferably adapted to be mounted at 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 the end where the two are mated with each other is defined as "front" and the opposite direction is "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 periphery of the insulating base 11.

The insulating base 11 is made of an insulating material and is preferably combined with the plurality of first conductive terminals 13 by insert molding.

The insulating base 11 includes a base 111 and a tongue plate 112 protruding forward from the base 111. As shown in fig. 7 and 8, the seat 111 is a hollow block structure with a track shape, and the tongue plate 112 is a hollow rectangular block. The cavity inside the seat 111 and the tongue plate 112 are communicated to form a receiving groove 114 recessed from the rear end surface of the seat 111. The front end surface 1121 of the tongue plate 112 is closed and covers the front of the receiving slot 114. The upper and lower sides of the tongue plate 112 are in a fence shape, and the hollow part of the fence is communicated with the accommodating groove 114.

Referring to fig. 4, 5 and 7, the magnet 12 is rectangular and is preferably inserted and fixed into the receiving slot 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 reduce contamination by external ferromagnetic substances. The magnet 12 is preferably a neodymium-iron-boron magnet, and an insulating layer (made of epoxy resin, for example) may be added on the surface thereof to prevent electrical conduction with the first conductive terminals 13. The two side surfaces of the magnet 12 with the largest area are the magnetic pole surfaces, i.e. the two side surfaces are the N magnetic pole surface 121 and the S magnetic pole surface 122, respectively, and the two magnetic pole surfaces 121 and 122 face the upper and lower sides of the tongue plate 112, respectively.

Since the magnetic flux Φ of the magnet 12 is BS, the magnetic pole arrangement of the magnet 12 uses the upper and lower side surfaces with the largest surface area S as the two magnetic pole surfaces 121 and 122, so that the magnet 12 can obtain the largest magnetic flux when using the same ferromagnetic substance, which is beneficial to enhancing the magnetic attraction force.

Referring to fig. 4 to 8, the plurality of first conductive terminals 13 are distributed in two rows spaced up and down in the insulating base 11, and the two rows of first conductive terminals 13 are preferably arranged on the tongue plate 112 in a 180-degree rotational symmetry manner, so as to support a 180-degree rotational bidirectional butt joint. Two rows of first conductive terminals 13 are respectively filled in the hollow parts of the fences 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 and tightly attached to the N-pole surface 121 and the S-pole surface 122 of the magnet 12.

In the preferred embodiment, the first conductive terminal 13 is made of conductive material with magnetic conductivity, such as ferrite stainless steel or martensite stainless steel, for example, SUS430 stainless steel can be selected actually, which can conduct electricity to realize electrical connection and can also conduct magnetic lines.

The first conductive terminal 13 is a linear structure and is divided into a contact portion 131, a connecting portion 132 and a soldering portion 133 from front to back according to the functions at different positions. The connecting portion 132 is embedded in the base 111. The contact portion 131 extends forward from the connecting 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 soldering portion 133 extends rearward of the housing 111 for soldering 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 other opposite side is correspondingly attached to one of the magnetic pole surfaces 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 surface 1121 of the tongue plate 112, so that the tongue plate 112 forms a front stop for positioning the first conductive terminal 13. The front end of the contact portion 131 also 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 is deeper into the second electrical connector 2 than the magnet 12, so as to better conduct the magnetic force lines emitted by the magnet 12 forward to increase the magnetic attraction force between the first electrical connector 1 and the second electrical connector 2.

Referring to fig. 4 and 5, the first housing 14 is a hollow cylinder, and has an extension length greater than that of the insulating base 11. The first housing 14 is preferably made of metal material, and is sleeved on the periphery of the insulating base 11 to achieve the signal shielding effect and reduce the electromagnetic interference. The rear end of the first housing 14 is substantially flush with the rear end of the housing 11, while the front end of the first housing 14 extends forwardly beyond the housing 11. The first shell 14 substantially fits the outer periphery of the seat body 111 of the insulating seat 11, and has a distance with the outer periphery of the tongue plate 112, so as to surround the tongue plate 112 to form a mating cavity 142 for mating the second electrical connector 2.

The base 21 is made of an insulating material, and is preferably combined with the magnetic attraction piece 22 by insert molding, so that the magnetic attraction piece 22 is not fixed to the base 21 by glue dispensing, and the space and cost can be greatly saved compared with the conventional assembly structure.

As shown in fig. 4, 9 and 10, the front end of the base 21 is open to form a cavity 211, and the cavity 211 extends forward through the front end surface of the base 21. The upper and lower sides of the front end of the base 21 are respectively provided with a plurality of openings 212 communicated with the cavity 211. And the upper and lower two sides of the rear end of the base 21 are respectively provided with an installation groove 213, the front end of the installation groove 213 is communicated with the plurality of openings 212, and the installation groove 213 passes through the rear end surface of the base 21 backwards.

The rear end of the magnetic attraction piece 22 is substantially flush with the rear end of the base 21, the length of the magnetic attraction piece 22 is smaller than the length of the base 21, and the front end surface 221 of the magnetic attraction piece 22 is preferably exposed to the rear of the cavity 211, so that the magnetic attraction force can be increased by being closer to the first conductive terminal 13 for conducting magnetic force when the connector is connected.

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 abutting portion 231 and the tail portion 233 are bent and extended relative to the fixing portion 232, so as to have elasticity for abutting against the first electrical connector 1 or a circuit board (not shown) of an electronic device.

The abutting portion 231 includes a first extension 2311 extending obliquely forward and inward from the fixing element 26 and a second extension 2312 extending obliquely forward and outward from the first extension 2311. The first extension 2311 and the second extension 2312 are in arc transition connection, and a pair of contact points 2313 are formed at the connection position of the first extension and the second extension.

The two second conductive terminal modules 230 are respectively fixed on the upper and lower sides of the base 21. The fixing elements 26 of the two second conductive terminal modules 230 are correspondingly installed in the installation grooves 213 of the base 21, and the fixing elements 26 can be fixed in the base 21 by means of adhesion or interference fit. The plurality of second contacts 23 in each second contact module 230 correspond to the plurality of openings 212, and the mating portion 231 of each second contact 23 protrudes into the cavity 211 through the openings 212. The tail 233 of each second conductive terminal 23 extends rearward out of the base 21 for electrical connection with a circuit board (not shown) of an 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. The pair of contacts 2313 is located in the cavity 211 and in front of the magnetic attraction piece 22 for electrically contacting with the first electrical connector 1. The butting parts 231 of the two rows of second conductive terminals 23 on the upper and lower sides are arranged oppositely.

Referring to fig. 4 to 6, the second housing 24 is a hollow cylinder made of metal material and sleeved on the periphery of the base 21 to achieve the signal shielding effect and reduce the electromagnetic interference. The second housing 24 covers the two second conductive terminal modules 230.

As shown in fig. 12, when mated, the tongue plate 112 is located between two second conductive terminal modules 230 of the second electrical connector 2.

electrical connectors

1 and 2 can rotate 180 degrees to be in bidirectional abutting joint. The magnet 12 of the first electrical connector 1 is magnetically attracted to the magnetic attraction piece 22 of the second electrical connector 2 through the magnetic conduction of the first conductive terminal 13. Specifically, as shown by the arrow lead in fig. 12, the magnetic force lines emitted from the N-pole face 121 of the magnet 12 are guided to the front end position close to the magnetic attraction piece 22 through the attached first conductive terminals 13, pass through the magnetic attraction piece 22, and then are guided back to the S-pole face 122 of the magnet 12 through the first conductive terminals 13 on the other side, so as to establish a magnetic loop, so that the first electrical connector 1 and the second electrical connector 2 are magnetically attracted to provide a holding force for the two to be abutted.

In the first electrical connector 1, the first conductive terminal 13 with magnetic conductivity is further used to guide the magnetic force lines, and the magnetic attraction piece 22 is closer to gather the magnetic force lines to increase the magnetic attraction force, thereby avoiding additional introduction of magnetic conductive elements, simplifying the structural composition of the connector, and further reducing the volume of the connector. In addition, the first electrical connector 1 is configured with two rows of the first conductive terminals 13 in 180-degree rotational symmetry, which can provide a two-way plugging function and is convenient to use.

In the second electrical connector 2, the plurality of second conductive terminals 23 form an integral terminal module through the fixing element 26 and then are fixed on the base 21, so as to facilitate maintaining the positions of the second conductive terminals 23 to achieve reliable electrical contact.
