Description

Power supply device

The utility model relates to the field of electrical engineering and can be used in power supply devices, and more specifically in chemical current sources, including those based on primary elements.

A power supply device is known comprising cylindrical power elements located along one axis and electrically connected in series, located in a case, on the front side of which a terminal pin of positive polarity is fixed, and on the rear face, a terminal pin of negative polarity, electrically connected to the corresponding terminals of the first and last elements power supply (EP 0768724 A2, 1997).

Such a device has low operational reliability, since if it is improperly installed in the power compartment (reversing the polarity), it is possible to fail both the device itself and the device that requires power.

Of the known power supply devices, the closest to the claimed one is a power supply device containing at least one power supply element located in a case, on the faces of which a pair of main output contacts are fixed, each of which is electrically connected to the terminals of the power supply element of the corresponding polarity (PCT

01/67529 A1, 2001). A pair of output contacts of positive and negative polarity, made in the form of curly borns, in this arrangement are located mainly on the front face of the case, which has the correct geometric shape. An output contact of negative polarity can serve as the side surface of the case made of metal.

Such a device also has insufficiently high operational reliability. When installing the power supply device in the power supply compartment of the device, for example, when replacing a depleted or defective device, attention is required from the user so as not to reverse the polarity of the contacts. The presence of the human factor, especially in extreme situations, leads to errors that can lead to failure of both the power supply device itself and the apparatus in which it is installed. Measures of a constructive nature to prevent improper installation of the power supply device (making a case of an asymmetric shape, introducing elements - keys, etc.) are not always possible and, at least, complicate and cost up the power supply device and reduce its versatility.

The problem solved by the utility model is to create a power supply device devoid of the disadvantages of the prototype. The technical result provided by the utility model is to increase the operational reliability of the power supply device.

This is achieved in that in a power supply device containing at least one power supply element.

placed in a case, on the faces of which a pair of main output contacts is fixed, each of which is electrically connected to the terminals of the power supply element of the corresponding polarity, at least one pair of additional output contacts is inserted, each of which is electrically connected to one of the main output contacts and mounted on the front or the back of the case opposite the main output terminal of the same polarity. The location, area and shape of the output contacts on the front and rear faces of the case can be selected from the condition of non-intersection of the rotation patterns formed by the paths of motion of the bipolar output contacts during arbitrary rotation of the case around its longitudinal axis. The case may be made in the form of a body symmetrical with respect to its longitudinal axis, having a cross section in the form of a regular figure, and a section parallel to the longitudinal axis of the rectangle. Power elements can be made in the form of primary chemical current sources. A pair of main output contacts can be placed on the front face of the case, and a pair of additional output contacts on the rear face of the case. One of the pair of main output contacts and one of the pair of additional output contacts can be located on the front face of the case, and the other on the rear face of the case.

The above technical result is provided by the totality of the essential features.

Figure 1 shows the design of a variant of the power supply device with the placement of the main output contacts on

- 3 front faces of the case. Figure 2 shows the design of a variant of the power supply device with the placement of one of the main output contacts on the front side, and the other on the rear side of the case. In Fig. 3, Fig. 4 shows the design options of the output contacts.

The power supply device comprises a case 1 and power elements 2 located therein. In one of the constructive embodiments, on the front face 3 of the case 1, made, for example, of dielectric material, a pair of main output contacts 4, 5 is fixed, and on the back face b, a pair additional output contacts 7, 8 {Fig.1). Moreover, opposite (along the longitudinal axis of the case) of the main output terminal 4, for example, of positive polarity, there is an additional output terminal 7 of the same polarity, and opposite the output terminal 5 of negative polarity, an additional output terminal 8 of the same negative polarity is located. The output contacts 4, 5, 7, 8 are electrically connected to the terminals 9, 10 of the power elements 2 of the corresponding polarity, for example, by means of the connecting conductors 11 located in the case 1. For example, the terminal 9 of the positive polarity is connected to the output contacts 4 and 7, and the terminal 10 of negative polarity is connected to the output contacts 5 and 8. In another constructive embodiment (Fig. 2), one of the main output contacts is fixed on the front face 3 of the case 1, mainly of a cylindrical shape made of metal or dielectric material 4, for example, in the center of the front face 3, and - 4 additional output terminal 8 opposite to it in polarity, for example, in the form of a ring or an annular collar of the metal case 1, and on the back face b the main output terminal 5 and the additional output terminal are similarly fixed contact 7. In this case, the metal case 1 is insulated by means of dielectric gaskets (not shown in the drawing) from the output contacts 4, 7. The location, area and shape of the output contacts 4, 5, 7, 8 are mainly chosen from the condition of non-intersection of the figures rotations formed by the motion paths of the bipolar output contacts 4, 5, 7, 8 with an arbitrary rotation of the case 1 around its longitudinal axis (in Fig. 3, the paths are shown by broken lines). The design of the output contacts 4, 5, 7, 8 can, under these conditions, be diverse and represent, for example, cylindrical heels 4, 5 (and 7, 8), as shown in Fig. 3, or curly borns, flat petals, etc. They can be made in the form of a central patch 4 and a ring 8 (and, respectively, 7 and 5), as shown in figure 4. Case 1 is made predominantly in the form of a cylinder, an ellipsoid, a rectangular prism, etc., symmetrical with respect to its longitudinal axis of the body (in the form of a regular figure). Its cross section parallel to the longitudinal axis is a rectangle. The power elements 2 in number from one or more can be made in the form of primary current sources, collected, for example, in a column and connected electrically in series.

- 5 the apparatus, the power of which it provides, it is enough to install it in the power compartment, regardless of which face of the case 1, front 3 or rear b, it is oriented relative to the input contacts of the power compartment. This is especially important in extreme conditions, such as in the dark. In this case, the reliability of electrical contacting of the input contacts of the power supply compartment and output contacts 4, 5, 7, 8 of the power supply device can be improved if the input contacts are duplicated, i.e. In the power compartment, additional input contacts are located opposite (symmetrically) to the main input contacts of the corresponding polarity. In the case when the condition of non-intersection of the rotation figures formed by the paths of the bipolar output contacts 4, 5, 7, 8 on the corresponding face 3 or b of the case 1 is met when it is rotated around the longitudinal axis, the power supply device can be arbitrarily oriented when installed in the power compartment ( rotated) around its longitudinal axis. This creates additional convenience in operating the power supply device, especially in extreme situations. If the above condition is not met, to prevent improper installation of the power supply device with its arbitrary orientation around the longitudinal axis, it is usually envisaged to perform additional structural elements - grooves, protrusions, etc. in case 1 (not shown in the drawings) with corresponding response elements in the power compartment .

Zc-vvVi / - 6 based on eight series-connected power elements 2 of type D-0.55C, placed in a cylindrical case 1 with a diameter of 36 and a length of 90 mm. The output contacts 4 and 7 of positive polarity are made in the form of cylindrical patches with a diameter of 10 mm, placed in the center of the corresponding face 3 and b concentrically relative to the longitudinal axis of the case 1. The output contacts 5 and 8 of negative polarity are made in the form of rings with an inner diameter of 30 mm and an outer diameter 35 mm, also placed on the corresponding face 3 and b concentrically relative to the longitudinal axis of the case 1.

The power supply device, made in accordance with the utility model, has high operational reliability, it is convenient for the user when installed in the power compartment of the powered device.
