Abstract

The invention relates to a fuse holder comprising two housing elements which, once assembled, together form a tube in which a support for a fuse is accommodated. Each of the two housing elements comprises a contact for establishing an electrical contact with a terminal of a fuse housed in the support, when the support is installed between the assembled housing elements. The support may comprise means to ensure the correct position of each contact in its respective housing element. The support may also comprise means to ensure the correct orientation of the fuse in the support. The support may also comprise means for retaining a seal ensuring sealing between the two housing elements.

First claim

The invention claimed is:

1. A fuse holder, comprising:
a first and second housing elements which, once assembled, accommodate a fuse, wherein the fuse includes two connecting terminals and wherein the first and second housing element each includes a contact that make an electrical connection with one of those terminals; and
a support in which the fuse is accommodated in a position in which each of the terminals is electrically connected to the contact when the first and second housing elements are assembled together, wherein the support is mounted on the first housing element and is movable between an open position in which the fuse is mounted in the support and a closed position in which the contact of the first housing element and one terminal of the two connecting terminals of the fuse are engaged one in the other, wherein the contact is a female contact receiving a pin extending from the terminal of the fuse.

2. The fuse holder in accordance with claim 1 , wherein the support is introduced into an opening of the first housing element in the closed position and wherein the support fitted with the fuse cannot be introduced into this opening if the fuse is not correctly positioned in the support.

3. The fuse holder in accordance with claim 1 , wherein the pin has a rectangular cross section and the support includes a slot, also rectangular in cross section, in which the pin is snugly inserted, with an orientation making introduction of the pin into the female contact possible.

4. A fuse holder, comprising:
a first and second housing elements which, once assembled, accommodate a fuse, wherein the fuse includes two connecting terminals and wherein the first and second housing element each includes a contact that make an electrical connection with one of those terminals; and
a support in which the fuse is accommodated in a position in which each of the terminals is electrically connected to the contact when the first and second housing elements are assembled together, wherein the support is mounted on the first housing element and is movable between an open position in which the fuse is mounted in the support and a closed position in which the contact of the first housing element and one terminal of the two connecting terminals of the fuse are engaged one in the other, wherein the support includes blocking reinforcement means that is engaged behind the contact if the contact is correctly positioned in the first or second housing element in which it is mounted and that cannot be engaged behind the contact if the contact is not correctly positioned in the first or second housing element in which it is mounted.

5. The fuse holder in accordance with claim 4 , wherein the support is introduced into an opening of the first housing element in the closed position and wherein the support fitted with the fuse cannot be introduced into this opening if the fuse is not correctly positioned in the support.

6. A fuse holder, comprising:
a first and second housing elements which, once assembled, accommodate a fuse, wherein the fuse includes two connecting terminals and wherein the first and second housing element each includes a contact that make an electrical connection with one of those terminals;
a support in which the fuse is accommodated in a position in which each of the terminals is electrically connected to the contact when the first and second housing elements are assembled together, wherein the support is mounted on the first housing element and is movable between an open position in which the fuse is mounted in the support and a closed position in which the contact of the first housing element and one terminal of the two connecting terminals of the fuse are engaged one in the other; and
a seal to provide the seal between the first and second housing elements, wherein the support includes a retaining element that retains the seal on the first housing element when the first and second housing elements are not assembled together.

7. The fuse holder in accordance with claim 6 , wherein the first housing element on which the seal is mounted has a rim overlying the seal to protect it when the first and second housing elements are not assembled together.

8. The fuse holder in accordance with claim 6 , wherein the support is introduced into an opening of the first housing element in the closed position and wherein the support fitted with the fuse cannot be introduced into this opening if the fuse is not correctly positioned in the support.
