Description

The utility model relates to the section of electricity and electronics, for the installation of elements, mainly electronic circuits, structurally designed in the form of clamping, spring devices used to fasten batteries to the board.

The prior art device for attaching a battery to the board [1], which contains a plate, mainly round in shape with the edges bent perpendicular upward, provided with four flanges directed towards the middle of the plate. Moreover, the bent edges form a closed loop with a U-shaped portion, inside of which a leaf spring is fixed on the surface of the plate.

The disadvantage of this device is the complexity of its design and manufacturing technology due to the presence of two separate elements - the plate and the leaf spring, as well as the need for their mutual fastening. In addition, there are some difficulties in the operation of the device due to the difficulty of dismantling the battery located in it and the need to use a tool for this.

Also known is a simpler, more technologically advanced and easy-to-use device for fastening the battery to the board [2], which contains a plate, mainly round in shape with the edges bent perpendicular upward, provided with an elastic flange directed towards the middle of the plate.

Moreover, the bent edges form an open loop with a U-shaped portion in which, occupying its entire area, a metal L-shaped element with a spring portion bent from the plate is fixed on the bent edge of the plate.

However, due to the presence of two parts in such a device, it still has some design complexity and manufacturing technology. Although the use of a tool for extracting a battery is not required in [2], it is necessary to manually bend elastic flanging for this, which is somewhat inconvenient and not quick. This reduces the efficiency of the device as a whole.

It is also known, adopted for the prototype of a utility model, a device for mounting a battery element, which contains a plate equipped with spring elements with curved edges forming an open loop, equipped with flanges [3]. The spring elements are located in the gap between the plate and its flanges and are made in the form of curved petals bent from the plate. The flanges are directed outward from the attachment device.

The objective of the utility model is to create a device for attaching a battery to the board, made in the form of one part, which should ensure the achievement of the following technical results: simplifying the design and manufacturing technology, as well as increasing the efficiency of the device for attaching the battery to the board, in particular fastening to boards with through slots, by pressing the battery on both sides of the board.

The problem is solved in that in the device for attaching the battery to the circuit board containing a plate equipped with spring elements with curved edges forming an open loop, provided with flanges, the spring elements being located in the gap between the plate and

its flanges and made in the form of curved petals bent from the plate, the flanges are directed inside the device in such a way as to provide coverage of part of the board on the back side with the battery pressed against the board.

The supply of the plate with flanges directed inside the device and the use of curved petals bent away from it allows a relatively simple technological operation (stamping and flexible) to obtain a device consisting of only one part, which confirms the simplicity of its design and its manufacturing technology.

The location of the spring elements in the form of curved petals in the gap between the plate and its flanges directed into the device is aimed both at preserving and even enhancing the effect of fixing the battery element inserted into the device, and at maintaining the convenience and speed of its dismantling from there. The enhancement of the fixing effect is ensured, in particular, due to the fact that the pressing of the battery is carried out on one side of the board by means of curved lobes, and on the other side of the board - by covering the board with the free ends of the flanges directed into the device.

This, at least by enhancing the fixation effect, will increase the overall efficiency of the device for attaching the battery to the board.

Additional distinguishing features of the utility model, reinforcing the above advantages of such a device:

- curved petals are made of a long part located at an acute angle to the plate, and a short part with an arched end located parallel to the plate;

- bent angular bevels of the plate are formed by bent edges; - through holes are formed by their long rectangular sides and their short arcuate sides near the bent corner bevels, and also formed by their other short sides rounded at the corners;

- one edge of the plate on its long side opposite the bent corner bevels is equipped with an arcuate notch with a large radius, and the other edge of the plate on its long side, near the bent corner bevels, is equipped with small arcuate notches with a smaller radius.

- the plate is predominantly rectangular in shape with the curved edges of its short sides perpendicular upward;

- applied two pairs of flanges made L-shaped and symmetrically located over the bent edges in their continuation with the direction of its free ends to the middle of the plate.
