Abstract

A terminal used to be mounted on a circuit board. The terminal includes: a first termination part; a second termination part; and a bending part connected between the first termination part and the second termination part. The bending part is bent by a predetermined angle relative to the first termination part and the second termination part, so that the first termination part and the second termination part are staggered by a predetermined distance along a direction transverse to a direction of inserting the terminal to the circuit board. When the terminal is mounted on the circuit board, one of the first termination part and the second termination part passes through the circuit board, so that two electronic devices located on both sides of the circuit board can be directly electrically connected through the terminal.

First claim

1. A terminal for being mounted on a circuit board, the terminal comprises:
a first termination part;
a second termination part; and
a bending part connected between the first termination part and the second termination part;
a fixing part connected to the bending part for fixing the terminal to the circuit board;
wherein the bending part is bent by a predetermined angle relative to the first termination part and the second termination part, so that the first termination part and the second termination part are staggered by a predetermined distance along a direction transverse to a direction of inserting the terminal to the circuit board;
wherein when the terminal is mounted on the circuit board, one of the first termination part and the second termination part passes through the circuit board;
wherein when the terminal is mounted on the circuit board, the first termination part is located on one side of the circuit board to electrically connect with a first electronic device located on the one side of the circuit board; and
wherein when the terminal is mounted on the circuit board, the second termination part passes through the circuit board to be electrically connected with a second electronic device located on the other side of the circuit board.

2. The terminal according to claim 1 ,
wherein the bending angle of the bending part relative to the first termination part and the second termination part is equal to 90 degrees; or
wherein the bending angle of the bending part relative to the first termination part and the second termination part is greater than 0 degrees and less than 90 degrees; or
wherein the bending angle of the bending part relative to the first termination part and the second termination part is greater than 90 degrees and less than 180 degrees.

3. The terminal according to claim 1 ,
wherein the bending angle of the bending part relative to the first termination part and the second termination part is equal to 90 degrees;
wherein when the terminal is mounted on the circuit board, the first termination part and the second termination part are perpendicular to the surface of the circuit board, and the bending part is parallel to the surface of the circuit board.

4. The terminal according to claim 1 ,
wherein when the terminal is mounted on the circuit board, the first termination part and the bending part are located on the same side of the circuit board.

5. The terminal according to claim 1 ,
wherein the fixing part is arranged on the side of the bending part;
wherein the fixing part is not parallel to the first termination part or the second termination part.

6. The terminal according to claim 1 ,
wherein the fixing part comprises:
an insertion part adapted to be inserted into a first hole in the circuit board in an interference fit manner to fix the terminal to the circuit board; and
a positioning part connected between the insertion part and the bending part and having a shoulder adapted to be supported and welded on the surface of the circuit board.

7. The terminal according to claim 6 ,
wherein when the terminal is mounted on the circuit board, the shoulder of the positioning part is supported on the surface of the circuit board, so that the bending part is spaced from the surface of the circuit board.

8. The terminal according to claim 1 ,
wherein the bending part is in a rectangular plate shape and has a pair of parallel first side edges and a pair of parallel second side edges;
wherein the first termination part and the second termination part are respectively connected to the pair of first side edges of the bending part;
wherein the fixing part is connected to the second side edge of the bending part.

9. The terminal according to claim 1 ,
wherein the first termination part and the second termination part are tongue shaped;
wherein the second termination part has a tongue part adapted to be plugged into a second electronic device;
wherein the thickness and/or width of the tongue part of the second termination part is different from that of the first termination part.

10. The terminal according to claim 9 ,
wherein the second termination part also has a base plate part, which is connected between the tongue part and the bending part;
wherein the thickness and/or width of the base plate part is different from that of the tongue part, and the base plate part is adapted to be inserted and positioned into a second hole in the circuit board.

11. The terminal according to claim 10 , wherein the thickness of other parts of the terminal except the tongue part is the same, and the thickness of the tongue part is different from the thickness of other parts of the terminal.

12. A central electrical box, comprising:
a box body;
a circuit board installed in the box body; and
the terminal according to claim 1 , which is mounted on the circuit board.

13. The central electrical box according to claim 12 , further comprising:
a connection terminal provided on the circuit board; and
a safety device, including:
a housing with two slots; and
a fuse received in the housing,

wherein the first termination part and the connection terminal are respectively inserted into the two slots of the safety device to be electrically connected with two pins of the fuse.

14. The central electrical box according to claim 12 , further comprising:
a cable connector having an insertion slot,
wherein the second termination part of the terminal is inserted into the insertion slot of the cable connector to electrically connect with the cable connector.
