Description

  The present invention relates to a connector for testing an electronic component such as an electric double layer capacitor.

  Recently, an electric double layer capacitor has been attracting attention as an electric storage means. Although the electric double layer capacitor has a cylindrical shape, it has a unique shape such as a flat shape (square shape) and a laminate shape. The flat shape (square shape) is formed by alternately stacking electrode plates and separators and storing them in a flat shape (square shape) aluminum case. The laminate shape is a thin shape with a reduced number of layers and sealed with an aluminum laminate film. Each of these flat (square) and laminated capacitors has a pair of flexible thin plate-like electrode tabs protruding in parallel from one side.

  In the case of performing a performance test such as charging / discharging with such a thin electrode tab, conventionally, the electrode tab is held by a crocodile clip and connected to a test apparatus. However, this method is convenient because the test can be performed regardless of the distance between the electrode tabs, but there is a problem that the clip is easily detached and the surface of the electrode tab is damaged or bent.

In addition, there are electrode tabs that can be held between a pair of openable and closable jaws, but the apparatus is large and the operability is not good.

  The present invention provides a test connector capable of firmly holding a thin plate-like electrode tab of an electronic component such as an electric double layer capacitor type battery by a simple operation.

  A test connector according to the present invention is provided on at least one of two upper and lower sandwiching plates for sandwiching a thin plate-like electrode tab extending from an electronic component, and held by the sandwiching plates. Left and right contact terminals that are in electrical contact with the electrode tabs, a plurality of lower struts extending downward from the upper clamping plate through the lower clamping plate, and a plurality extending upward from the lower clamping plate through the upper clamping plate The upper struts, a pressing member supported on the upper struts, and a spring contracted between the pressing member and the upper sandwiching plate in a fashion along the upper struts.

  In this case, when the pressing member is pushed down, the lower clamping plate is lowered via the upper support column, and the space between the lower clamping plate and the upper clamping plate is enlarged. The electrode tab of the electronic component is inserted into the gap. When the force is applied to the pressing member, the lower clamping plate is pulled up by the repulsive force of the spring, and the electrode tab can be brought into firm contact with the left and right contact terminals attached to the clamping plate. As described above, in this case, the electrode tab can be firmly held by a simple operation by simply pressing down the pressing member, and the structure is very simple.

  In addition, it is preferable that one of the plurality of upper columns is arranged so as to stand between the left and right contact terminals. If it carries out like this, the positive / negative pole of an electrode tab can be correctly distributed to the corresponding positive / negative contact terminal, and a short circuit can be prevented.

  The left and right contact terminals are preferably composed of a current supply terminal and a voltage measurement terminal, respectively. In this way, even when a large current flows, there is an effect that the terminal voltage of the electronic component can be accurately measured without being affected by the voltage drop.

  One of the current terminal and the voltage terminal may be arranged on the upper clamping plate and the other may be arranged on the lower clamping plate, but both terminals may be arranged side by side on one clamping plate. In the latter case, the sandwich plate may be formed of a printed board, and the current / voltage terminals may be formed as a metal thin film on the board by etching.

  In FIG. 1, reference numeral 1 denotes a laminated electric double layer capacitor as a battery, and a pair of flexible thin plate-like electrode tabs 2 extend in parallel from one side thereof. The upper and lower clamping plates 10 and 11 sandwich these electrode tabs. The upper sandwiching plate 10 is a long and narrow plate made of plastic, and a pair of left and right contact terminals 12 made of a metal piece having a jagged surface are attached to the lower surface thereof with a gap therebetween. A terminal block 14 electrically connected to these contact terminals is on the upper side of the holding plate, and the electric wire 15 is connected thereto. The lower clamping plate 11 is made of an elongated printed board, and a metal foil portion formed on the upper surface thereof forms a pair of left and right contact terminals 13. Reference numeral 16 denotes an electric wire connected to the contact terminal 13 on the printed board.

  The upper stage clamping plate 10 has columns 18 extending downward from the vicinity of both ends. These columns penetrate the lower stage clamping plate 11 and are fixed to an elongated plastic base 19.

  On the other hand, three upper support columns 17 extend upward from the lower support plate 11 through the upper support plate 12, and an elongated pressing member 20 is supported on these upper support columns. A coil spring 21 is contracted between the pressing member 20 and the upper clamping plate 10 so as to follow the column 17.

  In order to connect the electric double layer capacitor 1 to this connector, a hand is placed on the pressing member 20 and the pressing member 20 is pushed down against the repulsive force of the spring 21 as shown by a chain line in FIG. . Then, as shown by a chain line in FIG. 2, the space between the upper and lower clamping plates 10 and 11 opens, and a pair of electrode tabs 2 are inserted between them (see also FIG. 3 (1)). When the hand is released from the pressing member 20 in this way, the spring 21 expands, the lower holding plate 11 is drawn to the upper holding plate 10, and the electrode tabs 2 are contact terminals 12, 13 provided on the respective holding plates. (See Fig. 3 (2)). In order to prevent both electrode tabs from being held by the same contact terminal and being short-circuited, the pair of electrode tabs 2 must be inserted so that the central column 17 enters between them. To. If it carries out like this, each of both the electrode tabs 2 will be distributed to a corresponding contact terminal, and it can prevent a short circuit.

  In this state, a charge / discharge test is performed. At this time, the metal piece contact terminal 12 to which the upper holding plate 10 is attached is used as a current supply terminal, and the contact terminal 13 on the lower holding plate 11 (printed circuit board) is used as a voltage measurement terminal.

  In the above embodiment, the current terminal and the voltage terminal are arranged separately on the upper and lower holding plates, but in the next embodiment, both the current and voltage terminals are arranged together on the lower holding plate.

  That is, as shown in FIG. 4, two elongated contact terminals 12a and 13a arranged in parallel in the front-rear direction are formed on the lower clamping plate 11a. The lower clamping plate 11a is formed of a printed circuit board, and the contact terminals 12a and 13a are formed in the form of a metal thin film on the upper surface thereof by an etching process. The four contact terminals in total, left and right, are led to the terminal portion 23 by the linear thin film portion 22 to which the external electric wire 16 is connected. The upper clamping plate 10 is not provided with a contact terminal.

  When used, the electrode tab 2 of the capacitor 1 is placed so as to straddle the front and rear contact terminals 12a and 13a, and is sandwiched from above by the upper clamping plate 10 in the same manner as in the previous embodiment. Then, each electrode tab 2 is in electrical contact with the front and rear terminals 12a and 13a. By supplying a current from one of the front and rear contact terminals 12a and 13a and measuring the voltage on the other, accurate measurement can be performed without being affected by the contact resistance as in the case of the above embodiment. . In this case, since the current and voltage terminals are formed on the printed circuit board as a metal thin film, there is an advantage that the number of parts is small and the structure is extremely simple.
