A mechanism has been devised that allows the battery to be replaced with a freshly charged battery. has been done. Removable battery with sliding channel and latching mechanism It has been found desirable to securely fasten it to microelectronic equipment. But long As devices become smaller, the interface between batteries and electronics will become smaller. It is becoming increasingly difficult to control the dimensions of critical features for

Critical interface features include slide channels, latches and battery contacts. include.

Typically, the battery housing includes a housing base and a housing cover. assemblies that are coupled together to A gas chemical cell is included. Slide channel function section (sI fdin g channel features) are often attached to the housing base and Battery housing assembly as a combination of functional parts in housing cover located within. The assembly process of attaching the base to the cover is often inconsistent. This may lead to variations in the dimensions of the slide channel. Slide channel dimensions If the wobbling occurs, slide the latch and battery contacts on the battery housing. Change the relationship. As a result, batteries may not fit properly when installed in electronic devices. may not work or function properly. Therefore, all important interfaces The base features are manufactured as parts of the base, so that their dimensions relative to each other are It is advantageous to allow the law to be in control.

On manufacturing all important interface functions of the battery housing base Difficulties arise in creating guide rails for the sliding channels. vinegar The ride channel typically has three interior surfaces forming a "U" shape.

The guide rail is usually spaced on one of the two parallel sides inside the channel. It is a long and thin protrusion arranged at a distance.

The bottom surface of the channel is usually arranged perpendicular to the two sides. Said guide rail The curve is parallel to the base. Slide chart using traditional molding process panel, latch and battery contact receptacle inside the battery housing base. Expect straight pull-out from the molded tooling cavity.

However, the guide rail in the slide channel is located perpendicular to the direction of discharge from.

One approach being considered involves insert molding.

By using this process, the side of the slide channel containing the guide rail parts are first molded separately and then inserted into a second mold to form a slide chamfer. Two remaining sides of the panel and fully molded battery housing base form. The problem with this method is that it completes a two-step molding process. This means that it takes effort and time to complete the process.

Another approach being considered uses comolding. this By using this process, the sides of the slide channel including the guide rails are Molded separately in a first cycle. One piece of the tool is removed and a second part, the second part being a remaining functional part of the slide channel. and has a complete battery housing base. Second mold cycle opens A complete battery housing base is fabricated. The problem with this method is Performing the first stage molding in a straight drawing direction and the first stage drawing method. Automated co-mol to perform the second stage molding in the drawing direction perpendicular to the The main reason for this is the unavailability of tools for Special for battery housing base Developing a co-molding process would be expensive.

Therefore, it is easily manufacturable and has controlled and precise interface dimensions. Its exact interface dimensions are separate from the battery housing cover installation. Features an integrated, limited travel, sliding channel mechanism with guide rails There is a strong need for an improved battery housing base.
