Description of the invention j) (Technical field to which the invention belongs) The present invention relates to a terminal board provided with electrical parts for a variable resistor, etc., in particular A structure in which the terminal is mounted on a substrate. (Conventional technology) For example, in a variable resistor, a resistor body and a poly-body are formed on the surface of the substrate, and the slider moves on the substrate to become a slave resistor and A change in the resistance 値 can be detected at the end of the collector, and a plurality of terminals connected to the end of the resistor and the collector are mounted on the substrate. Conventionally, as a mounting structure of such a terminal, it is known to crimp the terminal with a buttonhole or weld it to a substrate. However, these systems have operational difficulties and are not suitable for automation. In addition, as a terminal mounting structure that does not require such buttonhole caulking or welding work, it is known to be described in Japanese Patent Publication No. 2-11 8 9 0 2 to make a clip-shaped terminal. Fig. 13 is an exploded perspective view showing a conventional terminal mounting structure using the clip-shaped terminal, and Fig. 14 is a sectional view showing the terminal mounting structure. As shown in these drawings, a resistive pattern 2 and a polyelectric pattern 3 are formed concentrically on the surface of the substrate 1, and the ends of the resistive pattern 2 and the polyelectric pattern 3 are coated with a conductive material such as eight 2 Of connection portions 2a, 3a. Terminals 4 are connected to each of the connecting portions 2a and 3a, and these terminals 4 have an elastic piece 4a holding the substrate 1 and a leg piece 4b extending rearward from the elastic piece 4a, and the elastic piece 4a and the foot The sheet 4 b is formed of a metal plate body. The elastic sheet 4 a is divided into three parts, and the central elastic sheet (please read the precautions on the back before filling this page). The size of the paper is applicable to Chinese national standards (CNS > A4 specification (210X297 mm) -4- Printed by the Central Standards Bureau of the Ministry of Economic Affairs of the Shellfish Consumer Cooperative Co., Ltd. $ A7 B7_ ._ V. Description of the invention 4 a and the two elastic pieces on both sides 4 a are bent in opposite directions to each other to form a clip-like shape as a whole. When the clip-like elastic piece 4 a is embedded in the substrate 1, the two elastic pieces 4 a on both sides are elastically connected to the connection portion 2 a (or 3 a). Since the central elastic piece 4 a is elastically connected to the back surface of the substrate 1, Each terminal 4 is mounted on the substrate 1 in a state of being electrically connected to the corresponding connection portion 2a (or 3a). (Problems to be Solved by the Invention) However, in the terminal mounting structure using the conventional clip-shaped terminal described above, three elastic pieces 4 a bent at opposite ends are formed at the tip of the terminal 4, and these elastic pieces 4 a are formed. They are elastically connected to the front and back surfaces of the substrate 1, respectively. For the leg piece 4b of the terminal 4, the substrate 1 is easy to change in the thickness direction. Therefore, there is a problem that the position accuracy of the leg piece 4b of the terminal 4 and the substrate 1Jt is difficult. In addition, since the plate surface of each elastic sheet 4 a is elastically connected to the surface or the back surface of the substrate 1, there is a limit in reducing the width of each elastic sheet 4 a, and * because each elastic sheet 4 a is folded differently from each other It is bent to form a clip shape. Therefore, the overall width of the terminal 4 cannot be reduced, and there is a problem that it cannot correspond to the narrow pitch of 2a and 3a. (Means used to solve the problem) The present invention is to form a rigid body piece with a cut section of a metal plate in the terminal and an elastic piece which is easier to deform elastically than the rigid body piece; the terminal is intended to be mounted on the substrate ... . ·, The cutting surface of the rigid body sheet is abutted against one surface of the substrate, and the elastic sheet is elastically attached to the other surface of the substrate. The structure is so, because the substrate is protected from elasticity, the paper size is subject to the Chinese Standard (CNS) A4 specification (2 丨 0X297 mm) ΤίΊ (please read the note 1f on the back before filling this page)

The accuracy of the position of the terminal's leg piece and the substrate, and because the rigid body of the terminal is abutted on the plate surface to be approximately orthogonal to one surface of the substrate, so the overall width of the terminal can be reduced, and it can correspond to the connection Pitch narrowing of the parts ((Embodiment of the invention) The terminal installation device * of the present invention is characterized by including a substrate on which a conductive pattern is formed, and a plurality of terminals made of a metal plate connected to the conductive circular connection portion. : The terminal is provided with a rigid body piece having a cut section abutting on one surface of the substrate, an elastic piece elastically connected to the other surface of the substrate, and a leg piece extending from the rigid body piece and the elastic piece. It is used as a circuit board for a variable resistor or various switches. For example, a variable resistor is a resistance substrate, and various switches are a switch substrate. In addition, the number of the conductive patterns can be appropriately increased or decreased as needed. For example, in the case of a resistance substrate, the combination of the resistance pattern of the conductive pattern and the polyelectrolyte pattern can be appropriately increased or decreased as the number of resistance circuits. The elastic sheet is more flexible than the rigid sheet, and may be formed by any one. For example, the elastic sheet is bent and processed into a part of the rigid sheet through a bending portion, and the plate surface of the elastic sheet can be elastically connected to the substrate. The other side. At this time, if the section where the elastic sheet is elastically attached to the substrate and the cut section of the rigid body sheet are in a straight line, the elastic force from the elastic sheet can be effectively applied to the cut section of the rigid body sheet.

In particular, when a reversing part is formed on the way of the elastic sheet and the direction is changed, and the front end of the elastic sheet is opposed to the rigid body sheet, the spring width required for the elastic sheet is made sufficiently long to make it compact. In addition, when the terminal forms a protrusion facing the upper rigid body sheet at a predetermined interval, and the cut surface of the protrusion is abutted to the other surface of the substrate, the two surfaces of the substrate are regulated as high rigid portions.

The operating body 1 1 is integrally formed with a cylindrical shaft portion 1 1 a and a receiving portion 1 1 b having a larger diameter than the shaft portion 1 1 a. The shaft portion 1 1 a protrudes from the bearing portion 1 0 c toward the frame body 1. 0 outside. A small-diameter protrusion 1 1 c is formed at the front end of the receiving portion 1 1 b, and the protrusion 1 1 c is fitted into a circular hole 14a passing through the substrate 14. In the embodiment, two slider plates 1 3 are fixed to the receiving portion lib by means of caulking or the like, and two slider pieces 1 3 a are formed on each slider plate 13. The operating body 1 1 is a state in which the bearing portion 10 c of the frame body 10 and the round hole 14 a of the substrate 14 are rotatable as a guide portion.

Description of the invention $) 16 and the polyelectrolyte pattern 17 are drawn to the edge of the substrate 14, and connection portions 16 a ′ 17 a made of a conductive material such as Ag are formed at these edges. Terminals 15 are connected to each of the connection portions 16a and 17a. Each terminal 15 is mounted on a substrate 14 as described below. Each terminal 15 is integrated into a synthetic resin holder 18 by external molding. The holding body 18 is fixed to the base plate 14 using the clips 18a on both sides. In addition, the base plate 14 is fixed to the open surface of the frame body 10 by appropriate means such as caulking, but as shown in FIG. 2 * since the frame body 10 b is located outside the movable tab 18 a of the holding body 18 Therefore, the flaps 18a will not spread to the outside, preventing the holding body 18 from coming off the substrate 14. As shown in FIG. 4, the above-mentioned terminal 15 is formed by pressing a metal plate having high elasticity such as phosphorous copper with a press, and has an L-shaped rigid body piece 15 a and an elastic piece 15 b opposite to the rigid body piece 15 a. And the leg pieces 1 5 c extending linearly from the connecting portion of the rigid body pieces 15 a and the elastic pieces 1 5 b. Also, after the press terminal 15, tin plating is applied to the entire area including the cut section. And other plating treatments to ensure contact reliability and good solderability. The plate surfaces of these rigid body pieces 15 a and the elastic pieces 15 b and the leg pieces 15 c are the same plane, and the contours of the terminals 15 are cut sections. The elastic sheet 15 b is reversed in the middle of the way, and its front end faces the rigid sheet 15 a at a predetermined interval. The interval is set to be smaller than the thickness of the substrate 14. Therefore, although the elastic sheet 15D is small overall, the spring width from the base end to the front end is set to be sufficiently long. The terminal 15 formed in this way is extrapolated in a state where the respective plates are arranged to face each other *, and the paper size of the rigid body sheet 1 5 a and the elastic sheet 1 5 b is applicable to the Chinese national standard (CNS) ) A Gut (210X297 mm) 7 ^ ~ (Please read the note on the back before filling in this page) Order the A7 of the Male Workers Consumer Cooperative of the Central Standards Bureau of the Ministry of Finance and Economics ____ B7 __ ^ _ V.

At this time, the arrangement pitch of each terminal 15 is set to be approximately the same as the arrangement pitch of each of the connection portions 16 a and 17 a. When the substrate 14 is embedded between the rigid body sheet 15 a and the elastic sheet 15 b of the terminal 15, as shown in FIG. 1, since the cut section of the rigid body sheet 15 a abuts on the back surface of the substrate 14, At the same time, the elastic sheet 15 b is flexed and elastically connected to the surface of the substrate 14. Therefore, the terminal 15 is mounted on the substrate 14 in a state of the connection portion 16 a (or 17 a) corresponding to the electrical connection. At this time, the substrate 14 is crimped to the cross-section of the rigid body sheet 15a with a reaction force accompanying the deflection of the elastic sheet 15b. For this direction, since the rigid body sheet 15a has a sufficiently large rigidity Without deformation, the relative position of the substrate 14 and the terminal 15 is correctly positioned based on the rigid piece 15a. Also, the parts of the terminal 15 are formed in a flat shape. The connection directions 16a and 17a are exposed. Therefore, the board surfaces of the substrate 14 and the terminal 15 are mounted approximately orthogonally to each other, and can correspond to the connection portions 16a, 17a. Narrow pitch. In addition, when the elastic sheet 15 b is flexed in this way, the bending stress is concentrated on the reversed portion of the elastic sheet 15 b. Therefore, when the terminal 15 is punched, the rolling direction of the flat metal plate is set to Arrows A-A in Figure 4.

Therefore, the action of the substrate 14 is The highly rigid protrusion 15d and the rigid body piece 15a are regulated from both sides. Excessive weighting will not be applied to the elastic piece 15b elastically attached to the surface of the substrate 14. As a result, the elasticity of the elastic sheet 1 5 b can be maintained for a long period of time, and the connection portion 16 a (or 17 a) corresponding to the elastic sheet 1 5 b can be maintained more reliably. 11 · {Please read the note on the back first Please fill in this page again) This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) A7 __ ^ _: _ B7_____ 5. Reliability of contact between inventions. As shown in FIG. 9, most of the rigid body piece 15 a is buried in the holding body 18. Since the terminals 15 are prevented from swaying to the holding body 18, at the same time, the rigidity of the rigid body piece 15 a is rigid. It is improved by the embedded portion of the holding body 18 *. Therefore, the reliability of the contact between the connection portions 16a (or 17a) corresponding to the elastic sheet 15b can be maintained more reliably from this point. In addition, as shown in FIG. 6, since the front ends of the flaps 18 a provided on both sides of the holding body 18 are locked to the base plate 14 and the frame body 10 respectively, the holding body 18 can be reliably prevented here.

The shape of the terminal 15 is not limited to the above-mentioned examples, and various modifications can be used. For example, the sheet surface of the rigid body sheet 15 a is subjected to corrugated punching and pressing to increase the contact area between the cut section of the rigid body sheet 15 a and the substrate 14, or it may be formed by omitting the reversing part of the elastic sheet 15 b The side view may be L-shaped. Alternatively, as shown in FIG. 10 and FIG. 11, the rigid body piece 20a having a cross-section formed at the terminal 20 and the elastic piece 20 bent at the rigid body piece 20a at a right angle are formed. b, and the leg pieces 20c extending linearly from the connecting portions of the rigid body pieces 20a and the elastic pieces 20b. When the terminal 20 is mounted on the base plate 14, the cut section of the rigid body piece 20a abuts on the substrate 1 4 It is also possible that the plate surface of the elastic sheet 20 b is elastically connected to the other surface of the substrate 14. Also, as shown in the embodiment shown in FIG. 12, the bent portion of the elastic sheet 20 b is offset, The section of the substrate 14 elastically connected to the elastic sheet 2 0 b and the rigid body sheet 2 0 a may be aligned with each other. At this time, because the elastic force from the elastic sheet 20 b cuts the section of the rigid body sheet 20 a: Therefore, the safety paper size of the terminal 20 can be increased.

The central government of the Ministry of Economic Affairs of the Central Bureau of Shellfish Consumer Cooperatives has a plurality of terminals made of metal plates, which include a substrate with a conductive pattern formed thereon and a connecting portion connected to the conductive pattern. The terminals have: A rigid body piece with a cut section on one surface of the substrate, and an elastic piece elastically connected to the other surface of the substrate, and a leg piece extending from the rigid body piece and the elastic piece are pressed because the substrate is subject to the elasticity from the elastic piece. Connected to the cut section of the rigid body sheet, the rigid body sheet becomes difficult to flex, so the position accuracy of the terminal leg piece and the substrate can be improved, and because the rigid body piece of the terminal is in contact with the board surface, One side is formed approximately orthogonally. Therefore, the overall width of the terminal can be reduced, and it can correspond to the narrow pitch of the connection part.
