Description

Electric connector, base and electric connector assembly

Technical Field

The present utility model relates to an electrical connector, a base and an electrical connector assembly, and more particularly, to a rotatable electrical connector, a rotatable base and an electrical connector assembly.

Background

As the market demand for cables is higher and higher, the specification requirements of the matched connectors are more stringent, and the connector assemblies of different interfaces are more and more emphasized. The structure of the contact interface determines the electrical and mechanical properties of the connector, such as resistance, insertion force and durability. However, in the connector assembly, the connector and the base thereof are connected, so that the connector cannot change direction due to the limitation of the contact interface, and the user can only use the connector according to the fixed direction after connection. If the direction of the cable at one end of the connector is moved or rotated in use, the connector cannot change direction, which easily causes damage to the pins of the connector and the internal structure of the cable, and even leads to reimbursement of the docking electronic device, so that an accident affecting safety is more likely to occur. In view of the above, in order to avoid the above situation and to improve the use of the connector assembly, there is a need for a connector assembly that has no directional limitation after mating, so as to solve the conventional structural problems.

Specifically, the arrangement of the rotary positioning device 29 can enable the first rotary base housing 23 and the second rotary base housing 24 to rotate under a force exceeding a certain force, and can achieve multi-stage circulation rotary positioning, so that the problem that the first rotary base housing 23 rotates under an excessively low force and cannot be effectively rotated and positioned is avoided. As shown in fig. 9, in some embodiments, the rotational positioning device 29 includes a plurality of positioning recesses 290, a rotational positioning slider 291, and a spring 292. Specifically, a plurality of positioning recesses 290 are provided around the outer wall surface of the base first rotary housing 23. In another embodiment, however, the plurality of positioning recesses 290 may be formed around the base second rotary housing 24 or the base third rotary housing 25. In some embodiments, the rotary positioning slider 291 and the spring 292 are disposed in the accommodating space 20 and connected to a corner of the base first insulating housing 21 (as shown in fig. 9), and one end of the rotary positioning slider 291 is sleeved into the spring 292, and the other end has a tapered interference portion for interfering with the plurality of positioning recesses 290.

With continued reference to fig. 9-11 and fig. 12-14. FIG. 12 is a top view of a base of an embodiment of the present utility model. Fig. 13 is a cross-sectional view of the electrical connector of fig. 12, taken along line 13-13'. Fig. 14 is a cross-sectional view of the electrical connector of fig. 12, taken along line 14-14'. The base shield slider 251 is disposed on the base third rotary housing 25, and one end of the elastic member 252 abuts against the base third rotary housing 25, and the other end abuts against the base shield slider 251 (as shown in fig. 11), wherein the elastic member 252 may be a compression spring. In some embodiments, the base shield slider 251 includes a plurality of guide holes 2510 and a plurality of shield guide blocks 2511. Specifically, the shielding guide blocks 2511 are correspondingly disposed below the sockets 230, and the guide holes 2510 are disposed adjacent to one side of the shielding guide blocks 2511, respectively. When the mating terminal of the mating object is not yet inserted into the socket 230, the shielding guide block 2511 of the base shielding slider 251 correspondingly shields each socket 230, preventing external dust, moisture or other foreign objects from entering the internal base terminal member (as shown in fig. 13). When the mating terminal of the mating object is inserted into the mating socket 230, the shielding guide block 2511 of the base shielding slider 251 is pushed away by the mating terminal due to the arrangement of the elastic component 252, and the mating terminal passes through the guide hole 2510 in a clockwise direction and enters the shielding hole 250 of the base third rotary housing 25 to contact the base center terminal 260, the base first pole terminal 261 and the base second pole terminal 262 (as shown in fig. 17). When the mating terminal of the mating object is pulled out of the base 2, the elastic component 252 pushes the base shielding slider 251 back to the position, and the base shielding slider 251 shields the shielding hole 250 of the lower base third rotary housing 25.

With continued reference to fig. 9-14. The base conductor member of the base 2 of the present application includes a first annular conductor 271 and a second annular conductor 272. The first annular conductor 271 is disposed between the base first insulating housing 21 and the base second rotary housing 24, and the base first pole terminal 261 is in electrical contact with the first annular conductor 271 (as shown in fig. 14).

In some embodiments, the first annular conductor 271 includes a first contact 2711, the second annular conductor 272 includes a second contact 2721 (as shown in fig. 9), and the first contact 2711 and the second contact 2721 are coaxially disposed, i.e., a center of the first contact 2711 coincides with a center of the second contact 2721. In particular, in order to prevent a short circuit from being formed between the first annular conductor 271 and the second annular conductor 272, the base 2 further includes a base spacer 28 made of an insulating material, which is provided between the first annular conductor 271 and the second annular conductor 272, so that the first annular conductor 271 is insulated from the second annular conductor 272 (as shown in fig. 13 and 14).

When the base 2 of the present utility model is used, the socket 230 of the base 2 is only required to be abutted with the abutting end of the electronic device (abutting object), and the base 2 can circularly rotate in multiple sections and in no direction, wherein the base first rotary shell 23 drives the base second rotary shell 24 and the base third rotary shell 25 to synchronously rotate, and keeps electrical conduction with the electronic device in the rotating process, so that a flexible use mode is provided for users, and the electric connector can have a larger playing space in circuit layout.

As shown in fig. 17, after the conductor members (i.e., the center conductor 370, the first outer conductor 371, and the second outer conductor 372) of the electrical connector 3 are inserted into the docking socket 230, the base shield slider 251 is pushed away by the conductor members of the electrical connector 3 due to the arrangement of the elastic assembly 252, and the conductor members pass through the guide hole 2510 in a clockwise direction and pass into the base third rotary housing 25, thereby contacting the base center terminal 260, the base first pole terminal 261, and the base second pole terminal 262 (as shown in fig. 17 and 18).
