Abstract

A fuse tap for a blade fuse is disclosed which includes a tap flange to which a blade of the blade fuse is received. The blade is retained within the opening by a plurality of teeth which exert a clamping force on opposite sides of the blade. A locking element is formed on the tap to lock the tap onto the blade fuse. A crimp connector is formed on one end of the tap which is adapted to be secured to a wire by crimping. The fuse tap is formed as a unitary one-piece body formed by bending a single blank of metal to provide the crimp connector on one end and the tap flange formed at the other end which includes an opening for receiving the blade of the blade fuse.

Claims

1. A fuse tap for a blade fuse having a pair of substantially parallel blades partially retained in a fuse body with a contact portion of each blade extending from the fuse body, the contact portions being adapted to be received in a fuse block, wherein the fuse tap comprises:

a body, said body being connected to an electrical conductor at one portion thereof; and

a tap flange formed on the body and having an opening defined therein for receiving the contact portion of one of the blades, wherein at least one tooth is formed on the opening which is adapted to securely engage the contact portion; and

a locking element is formed on the body at a predetermined distance from the tap flange corresponding to the dimension of the fuse body through which the blades extend in a parallel direction.

2. A fuse tap for a blade fuse having a pair of substantially parallel blades partially retained in a fuse body with a contact portion of each blade extending from the fuse body, the contact portions being adapted to be received in a fuse block, wherein the fuse tap comprises:

a body, said body being connected to an electrical conductor at one portion thereof; and

a tap flange formed on the body and having an opening defined therein for receiving the contact portion of one of the blades; and

wherein first and second sets of teeth are formed on opposite sides of the opening and extend in a distally convergent direction away from the fuse body when placed on the blade fuse, said blade having first and second oppositely facing sides which are contacted by the first and second sets of teeth respectively.

3. The fuse tap of claim 2 wherein the first and second sets of teeth are adapted to be displaced outwardly by insertion of the blade and the teeth exert a clamping force on opposite sides of the contact portion of the blade.

4. The fuse tap of claim 2 wherein a crimp connector is formed on one end of the body and secured to the electrical conductor, the electrical conductor comprising a wire to which the crimp connector is secured by crimping the connector to the wire.

5. A fuse tap for a blade fuse having a pair of substantially parallel blades partially retained in a fuse body with a contact portion of each blade extending from the fuse body, the contact portions being adapted to be received in a fuse block, wherein the fuse tap comprises:

a body having a connector formed on one end of the body and being adapted to be secured to a wire;

a tap flange formed at another end of the body and having a opening defined therein for receiving the contact portion of one of the blades; and

wherein a locking element is formed on the body at a predetermined distance from the tap flange corresponding to the dimension of the fuse body through which the blades extend in a parallel direction.

6. The fuse tap of claim 5 wherein spring biased contact elements are formed adjacent the opening defined in the tap flange and oriented to grip the contact portion of said one blade.

7. The fuse tap of claim 6 wherein said spring biased contact elements are formed from a single blank of metal.

8. The fuse tap of claim 5 wherein the locking element is formed from said single blank of metal.

9. The fuse tap of claim 5 wherein the crimp connector is provided with an insulating plastic sleeve.

10. A fuse tap for a blade fuse having a pair of substantially parallel blades partially retained in a fuse body with a contact portion of each blade extending from the fuse body, the contact portions being adapted to be received in a fuse block, wherein the fuse tap comprises:

a body, said body being connected to an electrical conductor at one portion thereof; and

a tap flange formed on the body and having a opening defined therein for receiving the contact portion of one of the blades, wherein at least one tooth is formed on at least one side of the opening which is adapted to securely engage the contact portion, said at least one tooth being formed from the tap flange as the opening is formed and extending into the opening, said at least one tooth being flexed outwardly by the contact portion of one of the blades to apply a resilient clamping force on the contact portion.
