Abstract

A power distribution connection apparatus comprises a busbar that includes a first frame body and a second frame body, where one end of the first frame body is connected to one end of the second frame body; a fastener that includes a fastening part and a first connecting part, where the fastening part is fitted outside the first frame body or the second frame body, and slides along the first frame body or the second frame body, there is a tooth needle mounting hole on the first connecting part, and the first connecting part and the fastening part are connected on one side of the first frame body or the second frame body; and a tooth needle, where one end of the tooth needle is plugged inside the tooth needle mounting hole, and the plugging depth is adjustable.

Claims

1. A power distribution connection apparatus, comprising:

a busbar comprising a first frame body and a second frame body, wherein one end of the first frame body is connected to one end of the second frame body;

a fastener comprising a fastening part and a first connecting part, wherein the fastening part is fitted outside the first frame body or the second frame body, and slides along the first frame body or the second frame body, and wherein a tooth needle mounting hole is on the first connecting part, and the first connecting part and the fastening part are connected on one side of the first frame body or the second frame body; and

a tooth needle, wherein one end of the tooth needle is plugged inside the tooth needle mounting hole, a plugging depth is adjustable, and a side wall of the tooth needle is in contact with a side wall of the first frame body or the second frame body to form an electrical connection between the busbar and the tooth needle, and wherein the other end of the tooth needle is connected to an external circuit breaker to concatenate the circuit breaker to an external circuit by using the power distribution connection apparatus.

2. The apparatus according to claim 1, wherein the apparatus further comprises a secondary busbar, wherein the secondary busbar comprises a third frame body, and wherein one end of the third frame body is connected to an opposite end of the one end of the first frame body or an opposite end of the one end of the second frame body.

3. The apparatus according to claim 2, wherein the apparatus further comprises a splicer, wherein the splicer comprises two contact ends and a second connecting part, wherein the two contact ends are located at two corresponding ends of the second connecting part, and that one end of the third frame body is connected to the opposite end of the one end of the first frame body or the opposite end of the one end of the second frame body comprises the other end of the first frame body and an opposite end of the one end of the third frame body, or the opposite end of the one end of the second frame body and the one end of the third frame body are respectively abutted against two sides of the second connecting part to form the electrical connection between the busbar and the secondary busbar by using the second connecting part, connection points of the first frame body and the third frame body, or the second frame body and the third frame body are separately located between the two contact ends, and the connection between the busbar and the secondary busbar is fastened by using the splicer.

4. The apparatus according to claim 3, wherein the apparatus further comprises at least two busbars, and wherein the at least two busbars are connected by using the splicer.

5. The apparatus according to claim 3, wherein the second connecting part is made of a conducting material.

6. The apparatus according to claim 2, wherein the secondary busbar is made of a conducting material.

7. The apparatus according to claim 1, wherein the apparatus further comprises buckles at two ends of the fastener, and wherein the buckles are used for a fixed connection between the fastener and the busbar or between the fastener and the secondary busbar.

8. The apparatus according to claim 1, wherein the busbar is made of a conducting material.

9. The apparatus according to claim 1, wherein the fastener is a captive fastener.

10. A communications system, comprising:

a power distribution connection apparatus;
