Battery spring connection structure

Abstract

The invention provides a battery spring connection structure, which comprises a battery spring and a contact cover connected with the battery spring, wherein the battery spring comprises a plurality of spring coil; the contact cover comprises a bottom board and a side wall extending from the edge of the bottom board and the internal face of the side wall of the contact cover is provided with at least one fixing part which clamps at least one spring coil at the tail end of the battery spring between the fixing part and the bottom board of the contact cover. The battery spring connection structure has the advantages of ensuring good contact and stable connection of batteries.

Description

technical field [0001] The invention relates to a battery spring connection structure, in particular to a battery spring connection structure for electronic products. Background technique [0002] In electronic products such as wireless keyboards and remote controllers, it is often necessary to connect a battery spring to the contact cover at the bottom of the battery compartment. When the battery spring is compressed, the battery can be easily inserted into the battery compartment. Then the battery spring pushes against the battery under the action of the elastic restoring force, so that the electrodes are in close contact with the metal contacts in the battery slot to conduct the current. [0003] Usually, the connection between the battery spring and the contact cover is maintained by the friction force between the outer side of the coil of the battery spring and the inner side wall of the contact cover. Since the contact cover is usually made of phosphor bronze and form...

Problems solved by technology

In order to ensure a frictional fit between the outside of the coil of the battery spring and the inside wall of the contact cover, the outer diameter of the coil usually needs to be slightly larger than the inner diameter of the bottom surface of the contact cover. The bottom surface of the contact

Only relying on the outer side of the spring coil to contact the inner side wall of the contact cover, in the process of repeated compression and elongation of the battery spring, the extrusion stress on the outer side of the spring coil will easily lead to misalignment or loosening of the battery spring, resulting in poor battery contact

At the same time, since the contact cover is in the process of stamping and deep drawing, a minimum slope of 2 degrees will be formed between its side wall and the bottom surface, that is, the opening of the contact cover is slightly larger than the bottom of the contact cover, so that the battery spring is easier to follow along the contact surface. The inside wall of the cover slides off and comes off
