Abstract

Embodiments of the present invention relate to an RRU device and an assembly thereof. The RRU device includes: an enclosure, where the enclosure includes a front-end plate and a back-end plate that are respectively set on two lengthwise ends of the enclosure, multiple parallel spaced heat sinks are set on two widthwise sides of the enclosure and between the front-end plate and the back-end plate, and the front-end plate and the back-end plate extend along a widthwise direction of the enclosure by a length which is greater than a length by which the heat sinks extend; and a joint part set on the enclosure, where the joint part is used to fasten two side-by-side radio remote unit devices together.

Claims

1. A radio remote unit device, comprising:

an enclosure; and

a transceiver, a power amplifier, and a duplexer that are installed in the enclosure, wherein the enclosure comprises a front-end plate and a back-end plate that are respectively set on two lengthwise ends of the enclosure, multiple parallel spaced heat sinks are set on two widthwise sides of the enclosure and between the front-end plate and the back-end plate, and the front-end plate and the back-end plate extend along a widthwise direction of the enclosure by a length which is greater than a length by which the multiple parallel spaced heat sinks extend; and

a threaded screw hole on the enclosure, for setting a position to a joint part, wherein the joint part is used to fasten two side-by-side radio remote unit devices together, so that the front-end plate and the back-end plate of one radio remote unit device respectively lean closely against those of the other radio remote unit device and a preset gap is formed between widthwise ends of heat sinks on opposite sides of the two radio remote unit devices.

2. The radio remote unit device according to claim 1, wherein:

the joint part comprises a screw hole set on the enclosure, a connection plate with a through-hole, and a screw;

when connecting the two radio remote unit devices, the connection plate is connected between the two radio remote unit devices by using the screw hole and the screw.

3. The radio remote unit according to claim 2, wherein:

the screw hole is set in at least one of the following locations;

a top end of the multiple parallel spaced heat sink;

a top end of the front-end plate and/or the back-end plate; and

a plane of the front-end plate and/or the back-end plate.

4. The radio remote unit according to claim 1, wherein:

one widthwise side of the front-end plate and/or the back-end plate comprises a concave part, and the other widthwise side comprises a convex part that matches the concave part;

when the two radio remote unit devices are adjoined together side by side, the concave part on one radio remote unit device assembles together with the convex part on the other radio remote unit device.

5. The radio remote unit according to claim 1, wherein:

the enclosure comprises an external interface connector set at the bottom thereof and used to electrically connect the radio remote unit device to another network device.

6. The radio remote unit according to claim 1, wherein:

the radio remote unit device further comprises a mount handle set on the enclosure.

7. An assembly of radio remote unit devices, wherein:

the assembly comprises at least two radio remote unit devices adjoined together side by side;

wherein

one or both of the at least two radio remote unit device comprises;

an enclosure; and

a transceiver, a power amplifier, and a duplexer that are installed in the enclosure, wherein the enclosure comprises a front-end plate and a back-end plate that are respectively set on two lengthwise ends of the enclosure, multiple parallel spaced heat sinks are set on two widthwise sides of the enclosure and between the front-end plate and the back-end plate, and the front-end plate and the back-end plate extend along a widthwise direction of the enclosure by a length which is greater than a length by which the multiple parallel spaced heat sinks extend; and

a threaded screw hole on the enclosure, for setting a position to a joint part, wherein the joint part is used to fasten two adjoined radio remote unit devices together, so that the front-end plate and the back-end plate of one radio remote unit device respectively lean closely against those of the other radio remote unit device and a preset gap is formed between widthwise ends of heat sinks on opposite sides of the two adjoined radio remote unit devices.

8. The assembly according to claim 7, wherein:

the joint part comprises a screw hole set on the enclosure, a connection plate with a through-hole, and a screw;

when connecting the two adjacent radio remote unit devices, the connection plate is connected between the two adjacent radio remote unit devices by using the screw hole and the screw.

9. The assembly according to claim 8, wherein:

the screw hole is set in at least one of the following locations;

a top end of the multiple parallel spaced heat sink;

a top end of the front-end plate and/or the back-end plate; and

a plane of the front-end plate and/or the back-end plate.

10. The assembly according to claim 7, wherein:

one widthwise side of the front-end plate and/or the back-end plate comprises a concave part, and the other widthwise side comprises a convex part that matches the concave part;

when the two adjacent radio remote unit devices are adjoined together side by side, the concave part on one radio remote unit device assembles together with the convex part on the other radio remote unit device.
