Description

  The present invention relates to a terminal device formed by bending a steel plate punched into a predetermined shape.

  Conventionally, electric motors (motor devices) have been used as drive sources for wiper devices, power window devices, slide door opening and closing devices mounted on vehicles such as automobiles, many of which employ brushed electric motors. Yes. This electric motor includes a motor body that houses an armature (rotor) to which a commutator that is in sliding contact with a brush is mounted, a reduction mechanism that decelerates the rotation of the armature, and a connector to which an external connector on the vehicle side is connected. And a connecting portion. Thus, the rotation force of the armature can be reduced by the speed reduction mechanism so that the driving force having a high torque can be output to the outside, and the electric motor is miniaturized to improve the mountability on the vehicle.

  Such an electric motor includes a plurality of terminal devices (terminals) between the connector connecting portion and the brush in order to supply a driving current from an external connector connected to the connector connecting portion to the brush. The terminal device is electrically connected to electronic components such as a choke coil and a capacitor. And since the terminal device with which the electric motor is mounted is mounted in a limited mounting space, it has a small and complicated shape.

  The terminal device is formed by punching a steel plate having conductivity into a predetermined shape and bending the punched steel plate a plurality of times. Such a terminal device is described in Patent Document 1, for example. Things are known. The terminal device (electrical connector terminal) described in Patent Document 1 includes a main body portion that forms a main body portion of the terminal device, a folded portion that is bent so as to be substantially perpendicular to the main body portion, The bent portion is provided integrally with the bent portion, and has a curved portion and a contact portion formed by further bending the end portion of the folded portion.

Further, when the folding part is bent with respect to the main body part, in order to prevent distortion (irregular deformation such as undulation) in the main body part and the folding part, a predetermined amount is provided between the two Is provided with a bending portion of a length of, that is, a folding margin. As a result, the main body part and the folded part are prevented from being distorted by bending the bent part (folding allowance), for example, securing the assembly stability of the terminal device to the assembly target, Occurrence of rattling of the terminal device with respect to the object can be suppressed.

The arc portion 45 functions as a folding margin for preventing the first vertical portion 42 and the second vertical portion 44 from being distorted when the connector-side terminal 24 is bent. The length of the arc portion 45 is Is longer, that is, as the radius is larger, the first vertical portion 42 and the second vertical portion 44 are less likely to be distorted. As described above, the connector-side terminal 24 includes the arc portion 45 that functions as a folding margin between the first vertical portion 42 and the second vertical portion 44, so the first vertical portion 42 and the second vertical portion 44 The suppression of the occurrence of distortion and the suppression of rattling of the connector-side terminal 24 with respect to the case 22 can thereby be achieved.

  As shown in FIGS. 6 and 7, a gap having a dimension L1 larger than the plate thickness dimension t of the connector-side terminal 24 is formed between the second vertical portion 44 and the terminal main body portion 40. A protruding portion 47 is integrally provided between the vertical surface f <b> 2 of the vertical portion 44 and the end portion 46 on the other end side of the terminal main body portion 40 so as to protrude toward the end portion 46.

On the opening side (upper side in the drawing) of each second connection portion 48, a taper portion 49 that gradually enlarges the opening is integrally formed, and each taper portion 49 is formed by the choke coil 23 or the bidirectional varistor. It plays the role which makes mounting | wearing of 25 easy.

  As shown in FIG. 7, the second vertical portion 44 has a substantially bilaterally symmetric shape with the terminal body portion 40 as the center. Therefore, the pair of upper and lower connector side terminals 24 shown in FIG. 4 are interchanged. Even so, the choke coil 23 and the bidirectional varistor 25 can be mounted without any trouble. That is, the connector-side terminal 24 has no mounting directionality and can be attached to the case 22 without confirming the upper side / lower side.

  A gap having a dimension L8 smaller than the plate thickness dimension t of the connector-side terminal 70 is formed between the tip of the protrusion 71 and the end 46, and the tip of the rolled part 72 and the vertical surface f2 are formed. A gap with a dimension L9 smaller than the plate thickness dimension t of the connector-side terminal 70 is formed between them. The gap dimension L8 is set to be smaller than the gap dimension L9 (L8 <L9). In addition, the gaps L10 and L11 are set between the tip of the rolled part 72 and the protrusion 71 and the first vertical part 42 (L10 <L11), respectively. The dimension is smaller than the width direction dimension w of the connecting portion 41.

  Also in the connector side terminal 70 according to the fourth embodiment configured as described above, the same operational effects as those of the above-described first embodiment can be obtained. In addition, according to the third embodiment, as in the second embodiment, the ratio of the protruding portion 71 and the rolling processed portion 72 between the vertical surface f2 and the end portion 46 can be increased. Therefore, the adhesion between the connector side terminals 70 can be more reliably suppressed. However, the protruding portion and the rolled portion can be formed, for example, two by two, or can be formed by offsetting each other by a predetermined amount on both sides of the terminal body portion 40 of the second vertical portion 44.

  It goes without saying that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, in each of the above-described embodiments, the terminal device according to the present invention is applied to the connector-side terminal 24. However, the present invention is not limited to this and can also be applied to the brush-side terminal 21. In this case, the brush-side terminal 21 and the connector-side terminal 24 can be shared by having the same shape.

  In each of the above embodiments, the terminal device according to the present invention is applied to the wiper motor 10 that swings and drives the rear wiper arm of the vehicle. However, the present invention is not limited to this, for example, the power for the vehicle. The present invention can also be applied to motor devices used as drive sources for window devices, sunroof devices, and the like.
