[0011]

[Problems to be solved by the device]

 However, two coil springs 6 and 7 must be inserted in each of the positive and negative coil spring housing grooves 2 and 4, which requires a lot of time and effort to assemble, resulting in poor workability. There is a risk that mistakes will occur. In addition, the number of positive and negative terminals is four, making it difficult to insert into the holes when mounting on the printed circuit board.

Further, the positive and negative battery contact terminals 8 and 10 are weak against a lateral force which may be received when the battery pack is mounted on the battery mount surface 1a, and such a deforming force causes the battery to be deformed. There was a problem that the contact terminals tilted sideways and the electrical connection became uncertain.

It is also known to use a leaf spring instead of the battery contact terminals by the coil springs 6 and 7, but the bending precision of the springy plate material is not uniform, and the contact pressure varies, resulting in reliability. There was a problem that it was inferior.

The present invention has been made in view of the above problems, and provides a connector terminal for a battery terminal plate that improves the assemblability of the battery terminal plate and resists lateral force during use. The purpose is to do.

[0015]

[Means for Solving the Problems]

 The gist of the present invention to solve the above-mentioned problems and achieve the above-mentioned object is a connector terminal which is internally housed in an insulating housing and has two contact terminals projecting outward from an opening of the insulating housing. The contact terminals are arranged symmetrically and punched and bent integrally, and the two contact terminals are paired in parallel. Furthermore, the two contact terminals have a gentle taper. It is formed in a mountain shape.

[0016]

[Action]

 According to the connector terminal of the present invention, since the two contact terminals are integrally formed with the fixing portion attached to the insulating housing, they should be assembled together when the connector terminals are incorporated into the insulating housing. Assembling workability is improved.

Further, since the two contact terminals have a mountain shape with a gentle taper, even if a force from the lateral direction is applied to a part of the contact terminals protruding from the insulating housing to the outside, the contact terminals can be deformed by resistance. The electrical connection is reliably retained. In addition, one terminal is used for two contact terminals, which is half the size of conventional terminals and facilitates the operation when mounting a battery terminal board incorporating connector terminals on a printed circuit board.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing a developed state of a connector terminal according to the present invention. FIG. 2 is a front view of the connector terminal.

As shown in FIG. 1, the connector terminal 20 includes mountain-shaped contact terminals 22 and 22 each having a gentle taper 21, an arm portion 23 that is bent in a substantially circular shape and exerts an elastic force, and an insulating housing. It comprises a fixed part 24 to be attached and a terminal 25 penetrating the hole of the printed circuit board 33 and connected to the circuit pattern.

Then, the connector terminal 20 is punched from a conductive flat plate into a shape as shown in FIG. The terminal 25 is bent at the base of the terminal 25 at about 90 degrees.

Thus, as shown in FIG. 2, the two contact terminals 22 and 22 are arranged in parallel to form a pair, and the fixing portions of the respective contact terminals 22 are integrated to form the fixing portion 24, which is the connector terminal 20. Is formed.

The connector terminals 20 are inserted into the positive and negative electrode contact terminal accommodating holes 29, 29 provided in the insulating housing 26. Then, the contact terminals 22 are projected to the outside from the battery mount surface 26a through the positive electrode battery contact terminal through holes 27 and 27 of the insulating housing 26 and the negative electrode battery contact terminal through holes 28 and 28.

On the other hand, the positive and negative terminals 25, 25 are projected to the outside from the printed board mounting surface 26b. The connector terminal 20 is secured by a fixture 30.

As shown in FIGS. 5 and 7, the battery terminal plate in which the insulating housing 26 and the connector terminal 20 are assembled in this way is formed by inserting two terminals 25 into holes formed at predetermined positions of the printed circuit board 33. After mounting, the battery terminal board is fixed to the print board 33 by dip soldering.

In this case, since there are only two terminals 25, the insertion work into the hole of the printed circuit board 33 is easier than the conventional battery terminal board having four terminals 9 and 11. Has become.

When the battery pack 31 is attached to an electric device such as a camera-integrated VTR having the printed circuit board 33 thus formed, the connection terminal 32 of the battery pack 31 and the contact terminal 22 of the connector terminal 20 are connected. The apex abuts, the contact terminal 22 is pushed downward in FIG. 7, and the arm portion 23 is bent by that amount.

Then, the arm portion 23 exerts an elastic force to press the contact terminal 22 toward the connection terminal 32 side, whereby electrical connection is surely made.

Further, even if a lateral force is applied to the contact terminals 22 protruding from the positive and negative battery contact terminal through holes 27 and 28, the contact terminals 22 are mountain-shaped plates and sufficiently resist, so The deformation and twisting due to the formation of the contact terminal by the coil spring does not occur in the contact terminal 22 of the connector terminal according to the present invention. Therefore, the reliable contact state is maintained between the connection terminal 32 and the contact terminal 22 of the battery pack 31, and the reliability is improved.
