Description

The invention relates to the field of primary non-rechargeable power sources, in particular to galvanic primary cells, or one-time power sources, and can find application in portable information transfer systems for powering portable transceiver devices with a long time interval of continuous operation from one single battery.

Known one-time (non-rechargeable) battery for portable transceivers "PRC-148 MBITR Thales Non-Rechargeable DL123 Battery Holder" company Thales (information is available on the Internet at http://www.prc68.com/I/PRC6725.shtml#PRC -152_Battery and http://www.prc68.com/I/Images/Thales123BHb.ipg). A single battery contains a one-piece housing made in the form of a rectangular parallelepiped. At the top of the battery case is a lid that is glued to the case. Two metal contact pads are installed on the lid, which additionally serve as a means of attaching the battery to the radio station. Under the lid in the cavity of the battery case of Thales radio stations, lithium-ion batteries are placed, connected to the battery by busbars made of electrically conductive material. A single battery for a Thales portable radio station is quite powerful and stable in operation, however, attaching the battery to the end of the radio station significantly increases the overall longitudinal dimensions of the transceiver. In addition, the fixation of the battery on the housing of the radio station is not rigid enough and does not prevent the mutual displacement of the paired devices from the action of torsion strain.

Known portable radio stations of a different type, removable disposable batteries of which have a curved shape and are installed not only on the end, but also on the rear panel of the radio station by the stepwise articulation of the battery with the transceiver with fastening on two mutually perpendicular surfaces of the transceiver body. These are, for example, compact portable radio stations Baofeng UV-5R, Motorola and others, however, the reliability characteristics of fastening single-use batteries of these transceiver devices do not correspond to the parameters of the claimed product.

The closest analogue of the present invention is a power supply for operation of the Baofeng UV-5R radio station from 6 AA batteries, including primary galvanic cells (information is available on the Internet at http://radio23.ru/akkumulyatory-zaryadnye-ustroystva/- 6aa and http://www.409shop.com/409shop_product.php?id=109304). The one-time battery pack for powering Baofeng UV-5R radios is a detachable rectangular pencil case with rounded longitudinal ribs and a figured step-shaped lid. On the side surface of the pencil case there are vertical ribs alternating with recesses for the convenience of gripping the battery pack with your fingers when installing or removing it from the radio transmitting device. Two contact pads, guide ribs and a plastic retainer are installed on the end surface of the pencil case body. The protruding part of the cover is made with rounded transitions between the planes. The internal cavity of the pencil case is divided into compartments to accommodate six batteries.

The selected closest analogue of the present invention does not provide the required level of operational reliability in terms of uninterruptible power supply in severe operating conditions.

The claimed invention is aimed at solving the problem of developing the design of a non-rechargeable one-time battery for powering a portable transceiver device with a large time interval of continuous operation of the transceiver from one single battery. In operating conditions, one single battery should provide the current consumption of the transceiver in the modes of “transmission”, “reception”, “standby reception” at a level of respectively 6.5 A, 1.3 A, 0.33 A with a ratio of the duration of the transmission / reception modes / standby reception corresponding to 1: 1: 9.

The technical result of the invention is to increase the reliability of a single battery by providing uninterrupted power and reliable electrical contact by rigidly fixing the one-time battery to a transceiver (consumer) with the possibility of operation in a wide temperature range, including in aggressive environments (including salt fog) and during mechanical stresses on the joint.

To solve this problem, a one-time battery is declared for powering a portable transceiver, comprising a step-shaped case in which non-rechargeable batteries are placed connected to contacts placed on the case of a one-time battery. The case of a single battery is equipped with fasteners to the transceiver, made detachable and provided with a step-shaped cover containing a flat part facing the rear wall of the transceiver and a protruding part in the form of a step. On the flat part of the cover as a means of fastening, a latch is made, made in the form of a metal spring-loaded latch, interfaced with a control element mounted on the upper transverse face of the step surface facing the end of the transceiver. On the lateral faces of the flat part of the lid there are longitudinal protrusions providing a sliding docking of the battery with the transceiver. The contacts are located on the upper end surface of the one-time battery case and are mounted on the contact module. The contacts are made nesting in the form of metal pads with a cutout in the central part and radial slots extending from the cutout with the formation of elastic petals bent into the cutout with the possibility of grasping the reciprocal-receiver contact.

In a preferred embodiment, a single battery contains on the upper end surface of the housing three contacts - positive, negative and backup, located on the contact module.

These contacts can be made of an alloy based on copper, mainly of beryllium bronze. Preferably, the contact module is in the form of a circuit board, additionally equipped with a protection module.

In a preferred embodiment, the protection module implements double protection against short circuit - by means of an electrical fuse introduced into the circuit, in particular a 16 A fuse, and by introducing a discharge current protection circuit designed for a discharge current I _{bit of} approximately 8 A. Protection function from a deliberate charge in the protection module is implemented by the protection unit on the diodes, which block the charge current from the power source.

In addition, it is preferable if the contact module is made with a lining in the form of a damping plate made of sealing material mounted on it and softening the docking of the battery with mating devices - a transceiver.

The removable cover of a single battery can be installed on its case using fasteners, preferably screws made of stainless steel or alloy steel with a protective anti-corrosion coating, in particular a protective galvanic coating, which allows the product to be operated in aggressive environments (including salt fog), high humidity, high ambient temperatures.

The latch may be made in the form of a metal spring-loaded latch with a spike protruding at a negative angle to the mating locking surface.

Preferably, the latch is made of spring steel grade 65G with a hardness of 440-490 units. on the Vickers scale to ensure a given stiffness of pairing with the transceiver body.

The single-battery case can be made with rounded longitudinal ribs, which makes it possible to conveniently hold the transceiver in hand during operation, and additionally, vertical protrusions are made on the side surfaces of the single-battery case, alternating with recesses, which makes it convenient to grip the battery case with your fingers when it is removed from or mounted on a transceiver.

In one embodiment, the case of a one-time battery is made of metal, preferably from aluminum-based alloys, and is externally coated with an oil and petrol-resistant paint coating suitable for use in aggressive environments in the temperature range from -30 ° C to + 55 ° C, and inside is coated with an insulating anticorrosive coated.

4 - contact module with protective equipment;

5 - contact;

6 - damping plate;

7 - control of the latch in the form of a button;

8 - a clamp;

9 - fasteners (screws).

On the flat surface of the battery cover 2, facing when connecting with the consumer to the transceiver (not shown), there is a metal latch 8 in the form of a spring-loaded latch, which secures the battery on the transceiver housing. The latch 8 is preferably made in the form of a figured strip of spring steel, for example, grade 65G, with a spike 11 protruding at a negative angle to the mating retaining surface. The retainer profile 8 is shown in FIG. 3. In the manufacture of the latch 8 is subjected to stamping and heat treatment to a hardness of 440-490 units. on the Vickers scale to give the desired rigidity to this element of the connection.

On the end surface of the battery, on the contact module board, there are three spring-loaded contacts 5, which are responsible for transceivers (rod contacts). Each contact 5 is made in the form of an oval plate 12, as shown in FIG. 4. Contact 5 is made of a material with high electrical conductivity and wear resistance, preferably of beryllium bronze.
