Abstract

A relay assembly comprises a relay mounted on a board. The relay may be a single or individual relay or a polyphasic relay. The relay has a housing and at least one dip solder pin extending from the housing and soldered to a circuit board. The relay is mounted on the circuit board via at least one fastening clip having a fitting part fitted into a hole in the housing, a latching part latched to a bore in the board, and a central flange between the fitting part and the latching part.

First claim

The invention claimed is:

1. A relay assembly, comprising a relay having at least one housing and at least one dip solder pin extending from the at least one housing and soldered to a board, wherein the relay is mounted to the board via at least one fastening clip having a fitting part fitted into a hole in the at least one housing of the relay, a latching part latched to a bore in the board, and a support flange between the fitting part and the latching part, wherein the latching part is compressed to be inserted through the bore along a direction from the flange to the latching part during assembly.

2. The relay assembly of claim 1 , wherein the support flange of the at least one fastening clip has a surface formed on an end thereof adjacent the fitting part and in contact with the at least one housing when the fitting part is fitted into the hole in the at least one housing.

3. The relay assembly of claim 2 , wherein the fitting part of the at least one fastening clip includes a press-fit finger having a cross shaped cross section which engages a complementarily shaped portion of the hole in the housing.

4. The relay assembly of claim 1 , wherein the fitting part of the at least one fastening clip includes a first fitting stage connected to the support flange and a second fitting stage connected to the first fitting stage.

5. The relay assembly of claim 1 , wherein the at least one fastening clip further includes a distancing ring surrounding a portion of the fitting part adjacent the support flange to adjust a distance between the housing and the board.

6. The relay assembly of claim 1 , wherein the fitting part of the at least one fastening clip includes a spacer leg coupled to the central flange, a latching recess connected to the spacer leg, and a latching head connected to the latching recess.

7. The relay assembly of claim 1 , wherein the latching part of the at least one fastening clip includes a spacer leg connected to the support flange to set a distance between the board and the at least one housing.

8. The relay assembly of claim 7 , wherein the latching part of the at least one fastening clip includes a latching recess coupled to the spacer leg and a latching head connected to the latching recess.

9. The relay assembly of claim 7 , wherein the latching part of the at least one fastening clip is elastic and compressed into the bore of the board.

10. The relay assembly of claim 7 , wherein the latching part of the at least one fastening clip further includes an intermediate recess and an intermediate latching head between the spacer leg and the latching recess.

11. The relay assembly of claim 7 , wherein the spacer leg of the at least one fastening clip is non-slitted, partially slitted, or completely slitted.

12. The relay assembly according to claim 1 , wherein the at least one fastening clip includes a plurality of fastening clips; the relay is a polyphasic relay having a plurality of housings stack mounted to each other; at least one first fastening clip of the plurality of fastening clips having the fitting part fitted in a hole in the housings and the latching part latched in a bore in the board; and at least one second fastening clip of the plurality of fastening clips having the fitting part fitted in a hole in a first housing of the plurality of housings and the latching part latched to a hole in a second housing of the plurality of housings.

13. The relay assembly of claim 12 , wherein the at least one second fastening clip further includes a distancing ring surrounding a portion of the fitting part adjacent the support flange to adjust a distance between the first housing and the second housing of the plurality of housings.

14. The relay assembly of claim 1 , wherein at least one of the fitting part and the latching part is laterally displaced with respect to a midline of the support flange.

15. The relay assembly of claim 1 , wherein at least one of the fitting part and the latching part has two or more variably-sized graduated press-fit pins or latching heads.

16. The relay assembly of claim 1 , wherein the support flange is of an oval design.

17. The relay assembly of claim 4 , wherein the diameter of the first fitting stage is larger than the diameter of the second fitting stage.

18. A relay assembly, comprising a relay having at least one housing and at least one dip solder pin extending from the at least one housing and soldered to a board, wherein the relay is mounted to the board via at least one fastening clip having a fitting part fitted into a hole in the at least one housing of the relay, a latching part latched to a bore in the board, and a support flange between the fitting part and the latching part, wherein the flange sets a distance between the board and the at least one housing.

19. A relay assembly, comprising a relay having at least one housing and at least one dip solder pin extending from the at least one housing and soldered to a board, wherein the relay is mounted to the board via at least one fastening clip having a fitting part fitted into a hole in the at least one housing of the relay, a latching part latched to a bore in the board, and a support flange between the fitting part and the latching part, wherein the at least one fastening clip further includes a distancing ring surrounding a portion of the fitting part adjacent the support flange to adjust a distance between the housing and the board.

20. A relay assembly, comprising a relay having at least one housing and at least one dip solder pin extending from the at least one housing and soldered to a board, wherein the relay is mounted to the board via at least one fastening clip having a fitting part fitted into a hole in the at least one housing of the relay, a latching part latched to a bore in the board, and a support flange between the fitting part and the latching part, wherein the at least one fastening clip includes a plurality of fastening clips; the relay is a polyphasic relay having a plurality of housings stack mounted to each other; at least one first fastening clip of the plurality of fastening clips having the fitting part fitted in a hole in the housings and the latching part latched in a bore in the board; and at least one second fastening clip of the plurality of fastening clips having the fitting part fitted in a hole in a first housing of the plurality of housings and the latching part latched to a hole in a second housing of the plurality of housings.
