Description

battery connector

technical field

The utility model relates to a battery connector, in particular to a battery connector comprising an insulating body, an insulating cover plate and a plurality of elastic terminals, the main body of the elastic terminal is located in the accommodation groove of the insulating body, and the cover plate is fixed on the insulating body. device.

Background technique

The existing battery connectors can be roughly divided into three types according to the structure of their elastic terminals. One type is the most traditional and the most commonly used. The connector of the elastic terminal, this kind of connector generally arranges this type of elastic terminal in an insulating shell for connecting with the battery. Since this connection uses a blanking type elastic terminal, there is The elasticity is not very good. In addition, when it is used, it is easy to break at the curved part, so its service life is short; second, the elastic terminal produced by blanking method can easily use the side of the elastic terminal when stamping. Deformation, causing difficult problems in installing the battery connector. The second type is a connector with elastic terminals with multiple elastic directions, such as a battery connector disclosed in Chinese patent document CN259188Y. Axial elasticity of different forces can achieve the effect that the terminal can move in various directions (refer to patent document CN2763986Y). It can be seen from its manual that this terminal can not only perform elastic movements in the front and rear directions, but also can perform elastic movements in the up and down directions, so that it can meet the use of different battery connectors and has strong versatility. However, since this kind of terminal needs to meet the elastic movement in the front and rear directions, as well as the elastic movement in the up and down direction, the elastic part of the terminal must reach a certain height. This height meets the increasing requirements of battery connectors. Miniaturization and thinning obviously cannot meet the requirements. The third type is the probe type battery connector, such as the battery connector disclosed in Chinese patent document CN2681381Y, which includes an insulating shell, at least three contact pieces and at least three elastic pieces, the insulating shell The body has at least three through holes, and these contact pieces are respectively installed in these through holes. out of the insulating case. The elastic parts of this type of connector generally use coil springs, which will lose their elasticity after a long time of use. In addition, their contact parts are arranged in a staggered manner, which is not suitable for making flat and thin connectors. The contacts are arranged in a straight line, and the springs must be of a certain size because the springs do not have the elastic force. If the spring is too small, the elastic force is not enough, and it cannot meet the requirement of being flat.

Among the above-mentioned three types of connectors, although the first type of products can meet the requirements of flat and thin, but because the elastic terminals used in them are made by blanking, there are many problems mentioned above; while the second and third types A common problem with connectors is that they are not suitable for making thin or ultra-thin battery connectors.

Contents of the invention

The technical problem solved by the utility model is to overcome the above shortcomings and provide a thin or ultra-thin battery connector with good elasticity, easy installation and long service life.

The technical solution of the utility model is: to design a battery connector, each elastic terminal of which is formed by bending a piece of metal sheet, and is serpentine as a whole.

A battery connector disclosed by the utility model includes an insulating body, an insulating cover plate and a plurality of elastic terminals. It at least includes a contact part, an elastic part and a welding part. The contact part is a closed serpentine shape formed by bending one end of a long metal sheet; the elastic part is bent by the middle section of the long metal sheet. The serpentine shape formed by the continuous connection of multiple folded S shapes. The welding part is at the tail of the elongated metal sheet and protrudes outside the insulating body. The head of the contact part is telescopically located on the side opposite to the welding part. Insulation outside the main body.

At the tail of the elongated metal sheet, there is a positioning part before the welding part, the shape of which is generally rectangular, and the positioning part is stuck in the positioning slot at the tail of the insulating body.

There are at least three holes distributed on the cover plate, and protrusions corresponding to the number and positions of the holes on the cover plate are distributed on the insulating body, and the holes and the protrusions are interference Cooperate.

There are lugs on both sides of the insulating main body perpendicular to the accommodated groove, and a fixing part is arranged in the lugs.

The lug has an elongated groove near the inner side of the insulating main body, and the fixing part is inserted into the elongated groove.

There is an opening outside the elongated slot of the lug, the side of the opening facing the same direction as the elongated slot is smaller than the side of the elongated slot, and there is a retaining edge on the side of the elongated slot close to the insulating body.

The welding portion protrudes from the insulating main body on one side of the cover plate.

Because the utility model adopts each elastic terminal of the connector, it is formed by bending a sheet of metal, and has a serpentine structure on the whole. In this way, compared with the elastic terminals made by blanking, It has the advantages of good elasticity and long service life; compared with the latter two types of connectors, it can be made into a thin or ultra-thin battery connector.
