Description

A kind of intercom battery

Technical field

The utility model relates to intercom battery technology field.

Background technology

Intercom is a kind of in-plant mobile communication equipment, and its emission or received signal all need be by means of battery ability operate as normal.The battery that is applied on the intercom mainly is a rechargeable battery, says that machine battery mainly contains two kinds of structure types, a kind of lithium battery as the integrated encapsulation used on the mobile phone, and the lithium battery of this integrated encapsulation damages the back and just can not use again; Another is to install to connect the intercom battery that the more piece cylindrical battery is formed in battery box, this class intercom battery is that the battery of battery case and Qi Nei is made of one indivisible form mostly, when this version is damaged when some batteries of the serial connection of battery case, just entire cell must be abandoned the use cost height.

The utility model content

Problem to be solved in the utility model provides a kind of intercom battery interchangeable electric core of detachable battery box, that use cost simple for structure is cheap that has.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

Design a kind of intercom battery, comprise battery box and be arranged on the interior electric core of box body, described battery box is formed by cover and bottom butt joint engaging, inwall place, cover rear and front end be provided with can with the contacted positive and negative electrode contact of electric core positive and negative electrode, the positive and negative electrode contact is connected with positive and negative electrode leading-out terminal on being arranged on bottom.

Improvement as such scheme, above-mentioned positive and negative electrode leading-out terminal is made up of " Z " sheet metal, positive and negative electrode leading-out terminal one end exposes on the bottom surface, be used for being connected with corresponding terminal on the intercom, the positive and negative electrode leading-out terminal other end is positioned on the bottom inwall, be used for cover on the positive and negative electrode contact join.

In the such scheme, cover is processed as box-like body, offers guide-track groove on the wall of the cover left and right sides, and described bottom is tile, and the bottom both sides are provided with the convex tendon that cooperates with guide-track groove.Also be connected with the press strip and the bolt that are used to compress in the battery box on the bottom inwall, step-like button bit and cover snapping that described bolt is provided with by its end.

The utility model has following remarkable result compared to existing technology:

The connection of the leading-out terminal on the both positive and negative polarity of the inside of this intercom battery serial connection battery and the battery box does not need lead to be connected, and conduction pattern is simple and reliable; The bottom of intercom battery is movably connected in box body surface and covers, and is locked on the cover by the bolt that is arranged on the bottom, and this locking mode is solid and reliable.

Intercom battery provided by the utility model, the relative bottom of box body cover can be scratched, and is convenient for changing the battery in the box body, needn't discard entire cell because a batteries damages, and use cost is low.

Embodiment

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.

Referring to Fig. 1～5, a kind of intercom battery is made up of battery box and the electric core 1 that is installed in the box body.Electric core in the box body is that the more piece cylindrical battery composes in series.Battery box is formed by cover 2 and bottom 3 butt joint engagings.Cover is processed into box-like body, the cover front inner wall is provided with anodal contact 6, the anode that is serially connected that is installed in the cover is docked on the anodal contact, and cover rear end inwall is provided with negative pole contact 7, and the battery cathode that is serially connected that is installed in the cover is docked on the negative pole contact.

Cover is processed as box-like body, offer guide-track groove 21 on the wall of the cover left and right sides, the bottom that fastens with cover is processed into the tile body consistent with the cover shape, and the bottom dual-side is extended with convex tendon 31, and the both sides convex tendon of bottom slides involutory fully until both along guide-track groove during fastening.

In order to make bottom and cover involutory more firm, the bottom inwall is provided with and is used to compress serial connection battery press strip 5 and the bolt of being installed in the box body 4, wherein bolt also is used for bottom is latched in cover, and the step-like button bit 41 and the cover that are provided with in the bolt end are interlockingly connected.

The mode that can adopt bonding of press strip and bolt is fixed on the bottom inwall, and fixed-direction is parallel with bottom convex tendon direction, so that better the battery pack that is serially connected is had good positioning.

When the bottom mouth is connected on the cover, be arranged on anodal leading-out terminal 61 on the bottom and negative pole leading-out terminal 61 just in time with cover on anodal contact 6 and negative pole contact 7 dock chucking and form electric pathway.The position of set positive and negative electrode leading-out terminal will be as the criterion with the positive and negative electrode contact that can be docked on the cover on the bottom.In order to strengthen the contact effect, the positive and negative electrode leading-out terminal is made up of " Z " sheet metal, have the through hole of mounting anode and cathode leading-out terminal on the bottom, positive and negative electrode leading-out terminal one end exposes on the bottom surface, be used for being connected supporting with contact terminal on the intercom, the positive and negative electrode leading-out terminal other end is positioned on the bottom inwall, be used for cover on the positive and negative electrode contact join.

Bottom of the present utility model is that activity is plugged on the battery cover, is convenient to change the box body internal cell.During installation, earlier a plurality of battery serial connections are installed in the cover, then the bottom convex tendon are sleeved in the cover guide-track groove, as shown in Figure 4, promote bottom to the F direction and make bottom slide, lock by bolt after slip puts in place along guide-track groove.When certain battery damage of electric core needed to change, the C direction promotion bottom that then makes progress earlier firmly pushed away to the D direction simultaneously, and then bolt can unclamp, and makes bottom leave cover and changes electric core.
