Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a discharge terminal board suitable for testing the discharge performance of batteries, especially so-called coin-shaped batteries, which have a large diameter compared to their thickness. The battery can be fully pressure welded, and by connecting the external terminal provided at the end of the board to a measuring device, various discharge performance adjustments can be made efficiently.

Conventional Structure and Problems Various discharge terminal plates have been devised in order to conduct an efficient battery discharge test 1.

For example, on one side of an insulating plate 2 constituting a substrate 1 shown in FIG. On the other side of 2, printed wiring 9 was provided for individual connection to the other poles of the battery. In the figure, 4 is a jig insertion hole, and 5 is a hole for attaching a fixing part of a clip for fixing a battery. However, in the case of a coin battery, where the diameter of the battery to be measured is approximately twice that of a button battery, the area required for the board is large, making it difficult to share the printed wiring portion with the button battery.

Purpose of the Invention The present invention is a discharge terminal developed for button-type batteries that is lightweight, compact, easy to carry, can be easily connected to an external measuring device, and is capable of automatic measurement and discharge control. The purpose of this is to allow the panel to be commonly used for large-diameter coin-shaped batteries.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a battery holder mainly consisting of printed wiring arranged on a substrate and an actuating terminal whose tip contact portion that touches the battery under test is formed in a cutout shape, and a substrate. The discharge resistor mounting provided on one side of the unit consists of a part, a discharge resistor, and an external terminal to be connected to the machine.
A bridge-like conductive foil placed on the printed wiring via an insulating layer makes it possible to place batteries on both sides of the board.
This makes it possible to perform discharge tests on button-shaped batteries and coin-shaped batteries.

DESCRIPTION OF THE EMBODIMENTS FIGS. 3 and 4 show an embodiment of the discharge terminal board of the present invention, showing the front side and the back side when a battery and a discharge resistor are attached. The claw plate 1 comprises an insulating plate 2 made of glass fiber reinforced plastic and printed wiring made of a highly conductive metal such as copper formed on the front and back sides of the insulating plate 2 as shown in FIGS. 1 and 2. It includes conductive foils 3, 9, external connection terminal parts 6, 10, and discharge resistor mounting holes 7, 8. The insulating plate 2 has a hole 5 for attaching a fixing member 15 of the battery holder shown in FIG. 6, and a hole 4 for inserting a jig to facilitate removal from the socket of the discharge end pre-loading and full discharge control panel. is provided.

Figure 6 shows a bridge-shaped conductive foil 2, which is the key point of the present invention.
0i When installed on the printed wiring 9 shown in FIG. 2, the bridge 20 consists of a glass fiber reinforced plastic board 21 forming an insulating layer and a highly conductive foil layer 22 provided on its surface. J where is in contact with the surface of the printed wiring 9
: It is attached to the substrate 1 with double-sided adhesive tape 25 or the like. The conductive foil layer 22 has a through-hole portion 23 to which a socket for attaching a discharge load resistor of the print I/wiring is soldered.
By soldering 26, it becomes a common terminal with the conductive foil 3 on the front side of the substrate 1.

FIG. 6 is a diagram showing the configuration of a part of the battery holder.

On the surface side of the substrate 1 shown in FIG. It is designed to be held completely. The actuating part terminal 11 is made of a highly conductive metal such as brass, and the surface is plated with nickel, etc., and is connected by a connecting pin 13 at a substantially medium heat part of a fixing member 16 made of the same kind of metal. It is biased by a spring 14 attached to a pin. The terminal 11 on the back surface is configured to come into pressure contact with a negative terminal 19 of a battery 18 placed on a conductive foil 22 provided on the back surface of the substrate 1. Several legs 16 of the fixing member 15 to the board are soldered 17 to individually divided conductive foil parts on the back side of the board through holes 5 provided in the board 1, and connected to external connection terminals 10. However, in order to accommodate a coin-shaped battery having a large outer diameter, as shown in FIG. 3, the front and back sides are alternately arranged in a staggered manner at every other terminal. For the missing parts, these movable terminals and fixed members are installed on the back side of the board in almost the same configuration as shown in Figure 4, and the mounting feet 16 are attached to the board surface through the entire hole 6. It is bent and fixed on the side, and its base is soldered 27 to the individually divided conductive foil portions 24 on the back side. A bridge 20 having a conductive foil 21 on the front side and an insulating layer 21 on the back side is placed on the printed wiring part 9 to insulate the wiring part, and the tip of the battery placed on the conductive foil 22 has a beak. It is configured to be held between actuator terminals 11 which are machined into a shape.

Effects of the Invention In this way, a bridge with conductive foil that contacts one terminal of the battery under test is insulated and arranged on the printed wiring part,
By arranging batteries in a staggered manner on both sides of the board, the same number of batteries can be stored in the same area, even if the diameters differ by about twice, and discharge tests can be performed by sharing the same printed wiring. be.

Furthermore, it is possible to move the discharge terminal board with the battery under test attached to a portion of the battery holder, which prevents incorrect battery insertion and fluctuations in the contact status between the battery and the terminal, and also allows for discharge performance testing. This makes it possible to move to various temperature conditions and change the discharge resistance while continuing to operate. In addition to these, by inserting and connecting all the external terminals of the printed circuit board of the discharge terminal board into the sockets of the products to be measured, automatic measurement of discharge performance tests is also possible.
