Electrical assembly
A demountable electrical panel comprises a spring under tension that is easily assembled by being laid to rest in a recess in a mounting plate put under tension to make electrical contact with a circuit board when the device is assembled.
1. An electrical assembly comprising:
a first member having a tapered recess;
a circuit board mounted on the first member, the circuit board having an electrical contact on a first side; and
a bent spring contact having a uniform width and a uniform thickness and being at least partially in the tapered recess, wherein:
a substantially flat first region of the bent spring contact is resiliently engaged with the electrical contact; and
a second region of the bent spring contact projects into and beyond the tapered recess.
2. An assembly as claimed in claim 1 in which the bent spring contact defines a projection resting within the tapered recess and an arm extending from the tapered recess defining the substantially flat first region in contact with the electrical contact.
3. An assembly as claimed in claim 1 in which the tapered recess defines a hole.
4. An assembly as claimed in claim 1 in which the second region of the bent spring contact comprises connected arms defining a taper projecting into the tapered recess.
5. An assembly as claimed in claim 1 in which the substantially flat first region of the bent spring contact comprises a limb extending from the second region.
6. An assembly as claimed in claim 5 in which the limb comprises a first part connected to the second region extending from the second region in one direction and a second part connected to the first part and extending generally in the opposite direction.
7. An assembly as claimed in claim 6 in which the second region of the spring arm defines a nub between the connected arms which projects through the hole.
8. An assembly as claimed in claim 2 in which the tapered recess defines a hole.
9. An assembly as claimed in claim 2 in which the second region of the bent spring contact comprises connected arms defining a taper projecting into the tapered recess.
10. An assembly as claimed in claim 3 in which the second region of the bent spring contact comprises connected arms defining a taper projecting into the tapered recess.
11. An assembly as claimed in claim 8 in which the second region of the bent spring contact comprises connected arms defining a taper projecting into the tapered recess.
12. An assembly as claimed in claim 2 in which the substantially flat first region of the spring contact comprises a limb extending from the second region.
13. An assembly as claimed in claim 3 in which the substantially flat first region of the bent spring contact comprises a limb extending from the second region.
14. An assembly as claimed in claim 8 in which the substantially flat first region of the bent spring contact comprises a limb extending from the second region.
15. An assembly as claimed in claim 4 in which the substantially flat first region of the bent spring contact comprises a limb extending from the second region.
16. An assembly as claimed in claim 9 in which the substantially flat first region of the bent spring contact comprises a limb extending from the second region.
17. An assembly as claimed in claim 10 in which the substantially flat first region of the bent spring contact comprises a limb extending from the second region.
18. An assembly as claimed in claim 11 in which the substantially flat first region of the bent spring contact comprises a limb extending from the second region.
19. An assembly as claimed in claim 12 in which the limb comprises a first part connected to the second region extending from the second region in one direction and a second part connected to the first part and extending generally in the opposite direction.
20. An assembly as claimed in claim 13 in which the limb comprises a first part connected to the second region extending from the second region in one direction and a second part connected to the first part and extending generally in the opposite direction.
