Abstract

A pluggable electrical connection device with anti-outward expansion function includes: two locking cams and a connector and a mating connector that are pluggably connected to each other. The mating connector has two locking portions and two first limiting bodies; the connector has a rotating shaft; each locking cam is rotatably connected to the rotating shaft and has a locking hook and a second limiting body, each second limiting body corresponding to and limiting the first limiting body. By rotating each locking cam relative to the connector, each second limiting body will limit the first limiting body to the first limiting body, and each locking hook will engage with the corresponding locking portion. This achieves the effect of preventing the two locking cams from outward expansion relative to each other during the reverse ejection of the connector using the two locking cams.

Claims

1. A pluggable electrical connection device with anti-outward extension function, comprising: A mating connector having two locking portions and two first limiting bodies; a connector pluggably inserted into the mating connector and having a rotating shaft; and two locking cams, each locking cam being rotatably connected to the rotating shaft and having a locking hook and a second limiting body, each second limiting body corresponding to and limiting each of the first limiting bodies; wherein each second limiting body is limited to each of the first limiting bodies by rotating each locking cam relative to the connector, and each locking hook is correspondingly engaged with each locking portion.

2. The pluggable electrical connection device with anti-outward expansion function as described in claim 1, wherein the first limiting body and the second limiting system are respectively a limiting groove and a limiting rib, and each limiting groove and each limiting rib limits each other by combining with each other.

3. The pluggable electrical connection device with anti-outward expansion function as described in claim 1, wherein each of the locking cams is located on two opposite sides of the connector and has a circumference, the connector has an abutment surface located between the two opposite sides, the mating connector has a corresponding abutment surface adjacent to the abutment surface, each of the first limiting bodies is disposed on the corresponding abutment surface, and each of the second limiting bodies is disposed on the circumference of each of the locking cams.

4. The pluggable electrical connection device with anti-outward tension function as described in claim 3, wherein the circumference of each of the locking cams is adjacent to or abutted against the corresponding adjacent surface.

5. The pluggable electrical connection device with anti-outward extension function as described in claim 1, wherein the locking cam is divided into a wheel body and a handle connected to each other, the wheel body is rotatably connected to the shaft and is provided with the second limiting body and the locking hook.

6. The pluggable electrical connection device with anti-outward tension function as described in claim 5, wherein the wheel body has an eccentric protrusion and the second limiting body is disposed on the eccentric protrusion.
