押し出して形威したベース係止用の突起である。FIG. 5 shows an example of an electronic component equipped with a metal case, and is an example of the configuration of a high-frequency coil. A bobbin 16 is fixed on a base 14 on which a terminal 12 is implanted.
A coil 18 is wound around the coil 18 . The coil body 10 consisting of the base l4, bobbin 16, and coil 18 is covered with a metal case 2o for shielding. The case 20 is fixed to the coil main body 10 by bending claws 22 integrally formed at the lower portions of two opposing sides inward. Note that 24 is a base locking protrusion formed by pushing out a part of the case 20 inward.
自動組立機による爪２２の折り曲げは、従来、次のよう

５図のように爪２２を折り曲げてケース２０をコイル本
体１０に係止していた。Conventionally, the claws 22 were bent by an automatic assembly machine as follows. First, as shown in FIGS. 6 and 7, a metal piece 30 having a ■-shaped slope 32 is attached to the case 20.
Press against the claws 22 on both sides and bend the claw I2 by the angle of the slope 32. Next, a metal piece 40 with a flat front surface 42 as shown in FIG. 8 is further pressed against the claw 22, thereby bending the claw 22 as shown in FIG. 5 and locking the case 20 to the coil body 10.
ところが、斜面３２を有する金属片３ｏを爪２２に押し

た。However, when pressing the metal piece 3o having the slope 32 against the claw 22, if there is a misalignment between the center axis of the metal piece 30 and the center axis of the case 2o, one of the claws 22a may not bend inward correctly as shown in FIG. Sometimes there isn't. If the metal piece 4o with a flat front surface is further pressed against the claw 22 in this state, the claw 22a will bend outward as shown in FIG. 10, or bend in the middle as shown in FIG. 11. was there.

の爪を折り曲げるようにしたものである。The present invention includes a pair of levers that are rotatably attached to opposite positions and a tapered cam that is movable back and forth, and constantly biases the front ends of the pair of levers to open. The case is inserted between the levers from behind to push the rear part of the lever apart, and at this time the claw of the case is bent at the front end of the lever that closes.

と端子１２の間を通過できるようにしてある。Four parts 52 are formed on the upper surface of the base 50 made of metal. A pair of opposing levers 3 4 60 are rotatably mounted in the recess 52 with their substantially central portions supported by a shaft 72 . Pins 74 fixed to the rear part 64 of each lever 60 are connected by a coiled spring 76 to always bias the front end 62 side of the lever 60 to open. As is clear from FIG. 2, the front end 62 of the lever 60 is made thinner than the lever body, and the terminal 12
and the terminal 12.

一対のレバー６０の間に後方から進入する。80 is a tapered plate-shaped cam with tapered surfaces 82 on both sides. The cam 80 is driven by an air cylinder (not shown) or the like so that it can move in the front-rear direction (vertical direction in the figure). When the cam 80 moves forward, the spring 76
The robot enters between the pair of levers 60 from behind while pushing apart the rear portions 64 of the pair of levers 60 against the force.
次に、本装置の動作について説明する。Next, the operation of this device will be explained.

曲げるものである。Next, when the cam 80 is moved forward, the lever 60 whose rear part 64 comes into contact with the tapered surface 82 and is pushed apart rotates around the shaft 72 as shown in FIG. 4 to close the front end 62 and close the case 20. Bend the claws 22 inward. After this, cam 8
When the lever 60 is moved backward, the lever 60 returns to the state shown in FIG. 1 due to the elasticity of the spring 76. After this, as in the conventional case, a metal piece 40 with a flat front surface 42 as shown in FIG.
By pressing against it, the claw 22 is bent into the state shown in FIG.

Of course, a spring that opens the lever 60 may be attached to the front part of the lever 60. Further, the cam 80 is not limited to a plate shape, but may be a rod shape or the like.

折り曲げが可能である。Since the device of the present invention bends the claw by applying force from the lateral direction, the claw can be reliably bent even if the central axis of the device and the central axis of the metal case are slightly misaligned. Also, the force is magnified by the taper angle of the cam, so
5 6 bending of the claws with small force is possible.
