Description

Connector assembly and electronic device

The present invention relates to a connector assembly and an electronic device, and more particularly to a connector assembly and an electronic device with coupling members located on opposite sides of a long axis of the connector.

The serial connection between electronic equipment and wires is usually done by using male and female connectors to improve the efficiency of assembling between electronic equipment and wires. However, when using electronic equipment, the mating male and female electrical connectors may be subject to collisions that may cause them to come loose or separate.

In order to reduce the probability of the mating male connector and the female connector being loosened due to a collision, the current manufacturer will add a screw lock function to the male connector and the female connector. For example, add screws to the female electrical connector and screw holes to the male electrical connector, such as D-Sub type connectors. When the male electrical connector is mated with the female electrical connector, attach the screw lock of the female electrical connector to the screw hole of the male electrical connector. In this way, the mating strength of the male electrical connector and the female electrical connector can be enhanced by means of the screw lock being attached to the screw hole.

However, the positions of the screws and screw holes on the electrical connector are limited by the original manufacturer's specifications and difficult to adjust according to actual needs. For example, two screws are attached to the D-Sub connector, and two 4-40 screws are respectively located on the long axis of the female electrical connector. In this way, after the male and female D-Sub connectors are mated, they only have a better resistance to the torsional force in the axial direction of the long axis. That is, there is less resistance to the torsional force from the short axis direction.

In addition, the D-Sub connector has 4-40 screws with an external diameter of about 2.8MM. Because the larger the outer diameter of the screw, the stronger the locking strength, but it is often restricted by the original manufacturer's public regulations and cannot be increased according to the actual needs. Therefore, it is difficult to effectively improve the mating strength of the electrical connector.

The present invention is to provide a connector assembly and an electronic device, so as to solve the problem that the positions and sizes of screws and screw holes on electrical connectors in the prior art are limited by the specifications of the original manufacturer, and it is difficult to adjust according to actual needs, thereby causing electrical connections. It is difficult to improve the docking strength of the device.

The first electrical connector is disposed on the host body. The second electrical connector is pluggably connected to the first electrical connector.

The first coupling member and the second coupling member are both disposed in the second electrical connector, and the first coupling member and the second coupling member are respectively disposed in the first coupling hole and the second coupling hole.

And the second shielding plate 243 includes two opposite short sides 243a.

The first coupling member 250 and the second coupling member 260 are respectively disposed on the second casing 241 through a reinforcing plate member 500.

Hole 331. Because the first coupling member 250 and the second coupling member 260 are butted to the first coupling hole 321 and the second coupling hole 331, respectively, the first coupling member 250 and the second coupling member 260 and the long axis A (as shown in FIG. 3) The positional relationship of the same as the positional relationship of the first coupling hole 321 and the second coupling hole 331 with the long axis A (as shown in FIG. 3) is not repeated. In addition, the first coupling member 250 includes a fixing cylinder 251 and a screw 252, and the second coupling member 260 includes a fixing cylinder 261 and a screw 262. The diameter D1 of the screws 252 and 262 is larger than the diameter D2 of the two locking members 400. The screws 252 and 262 are, for example, M4 screws. However, the arrangement of the reinforcing plate 500 is not intended to limit the present invention. In other embodiments, the first coupling member and the second coupling member may be directly disposed on the second casing. In addition, the arrangement of the fixing cylinders 251 and 261 of the first coupling member 250 and the second coupling member 260 is not intended to limit the present invention. For example, the first coupling member and the second coupling member may be screws directly.

According to the connector assembly and the electronic device of the above-mentioned embodiment, the first coupling member and the second coupling member provided in the second electrical connector are the first coupling hole and the second coupling hole of the assembly frame, rather than the locking. The lock hole of the first electrical connector can break through the size limitation of the original screw hole of the first electrical connector. If the D-SUB connector is used as an example of the first electrical connector, the screw specifications of the first and second coupling members can be upgraded from 4-40 screws, for example, to M4 screws, thereby improving the mating strength of the connector assembly.

In addition, because the first coupling member and the second coupling member provided on the second electrical connector are locked to the first coupling hole and the second coupling hole provided on the assembly frame, instead of being locked to the lock of the first electrical connector Holes, so the assembly frame can be used to break through the original screw hole position restriction of the original first electrical connector. That is, the positions of the first coupling member and the second coupling member are changed to be respectively disposed on opposite sides of the long axis. In this way, the first coupling member and the second coupling member are respectively locked to the first coupling hole and the second coupling hole, thereby enhancing the connector assembly's resistance to the torsional force from the short axis.

In addition, the assembly rack uses the fastener to pass through the perforation and the through hole of the host body, and is locked to the existing lock hole of the first housing of the first electrical connector, so that the assembly rack is fixed to the host body, so it will not The existing screw holes of the electrical connector are wasted, and no additional processing of the host body is required.
