In the press-fit terminal of this prior art Japanese Patent Laid-Open Publication No. 2015-82430, the press-fit portion is formed into a press-fit elastic pressure-welded portion for forming rigidity so as to maintain electrical contact and load after tightening with the tip guide end guided by the fastening hole Terminal,

The invisible elastic pressure-contacting portion having such a constitution has a pair of elastically deformable elastic pressure-contacting portions which are disposed with a hole of a bending space formed along the press-in direction interposed therebetween, and a pair of elastic pressure- A plurality of techniques differing in the form of the elastic piezoelectric portion described above are well known, together with the prior arts having a press-fit terminal having a connecting portion for connecting the connecting portion.

Japanese Unexamined Patent Publication No. 2015-90792 discloses a prior art in which the terminal is bent and provided so as to increase the assemblability and prevent the terminal from being bent and cut by the pressure during assembly and to make the electrical connection effective.

And a connector connection structure composed of a circuit board, a through hole formed in the circuit board, and an electrode face formed on a surface of the circuit board and a connector terminal elastically contacting and electrically connecting to the electrode face,

  A housing for holding an external connection terminal of the connector terminal is provided on a rear surface of the circuit board and an insertion portion into which the connector terminal is inserted into the hole with the metal rod portion, A bent portion is formed in an oblique state to constitute a contact portion which is in contact with the adjacent electrode surface in a curved state so that the contact portion makes elastic contact with the electrode surface.

These prior arts, as described above, are made of a simple rod together with an elastic pressure part having a width larger than the inner diameter dimension of the plated layer and the fastening hole on the surface of the metal wire cut to a predetermined length, There is a problem that when another substrate is fastened to a fixed or fixed terminal, it is easily bent or cut off when it is press-fitted into the fastening hole by an automatic machine or the like.

Prior art US 7,867,016 B2 (PRESS-IN CONTACT) for solving this problem is composed of a mounting part for mounting, a relief part, a switching part, and a press-fitting part, and an "S" -shaped compensating part is formed from the end of the switching part And connected to the mounting portion.

In this configuration, the compensating portion is elastically compressed so as not to damage the switching part or the like in the impact and pressure applied at the time of press-fitting, so that stable position maintenance and accurate soldering are induced in the solder point press-

The compensating part, which is compressed by the pressurizing pressure, is moved at a predetermined distance, and a slot short-circuited with the switching part is provided from the mounting part to control the moving distance of the switching part to be lowered.

The first embodiment of this prior art constitutes a compensating section extending outwardly from the lower end of the switching section, and is composed of a stationary piece and a slot which are lowered from the compensating section and upward from the mounting section together with the mounting section, A deflection occurs in one direction and a mounting portion is bent to bend the plate material to form a horizontal plane on one side, while a bent portion is formed as a curved plane, and a phenomenon that the plate is inclined along a bending plane occurs.

In order to improve the above-described disadvantages of the first embodiment, the second embodiment is configured such that an elastic portion is formed straight from the switching portion and is bent in a "U" shape to form a mounting portion extended from the elastic portion, And the extension portion is extended to both sides to form the switching portion and the slot. However, the mounting portion in such a configuration is formed as a curved surface of a "U" shape so that the mounting portion is eccentrically positioned at the time of press- I can not completely improve my luggage.

In the third embodiment, the mounting portion extending from the elastic portion is bent to the rear portion to form the mounting portion having the slot. However, since the mounting portion is composed of the end face portion of the plate member, soldering in the mounting and adhesion of a large area are poor, There is a problem that the soldering portion is removed during use.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in the perspective view of the entirety of the press-fit terminal A for the substrate connector of the present invention shown in FIG. 1, the first and second substrates 100 and 100 are fixed to the fastening holes 101 in the second substrate 110, An elongated plate-shaped switching part 10 constituting a control jaw 13 from an elastic pressure-contacting part 12 forming an elastic shaft 11 for the elastic part 15, and a switching part 10 for connecting the switching part 10 and the mounting part 20, .

A pair of guide pieces 14 extending outwardly are formed at the lower end side of the switching portion 10,

The elastic part 15 having a "⊂" shape or an "S" shape and extending integrally with a width and a thickness reduced at the center of the end of the switching part 10,

A mounting portion 20 having a control plate 21 which is bent in a " U "-shaped shape formed by an adhesive surface 16 whose bottom surface of the elastic portion 15 is horizontal,

A control board 21 bent upward from left and right sides of the mounting portion 20 having the adhesive surface 16 and formed to have a size including the guide pieces 14,

A control panel 21 constituting a guide hole 23 forming a slot 22 which is a moving space of the guide piece 14 while being vertically guided by the guide piece 14 is attached to the upper center of the control plate 21 The mounting portion 20 provided is not eccentric from the switching portion 10 toward the center,

When the press-fit terminal A for the connector of the present invention, which is press-fit in the soldering operation, is pierced through the through hole 24 in which the welding molten lead is received in the center of the adhesive surface 16 of the mounting portion 20, The molten lead flows into the through hole 24 and moves to the upper portion and is wrapped around the periphery of the through hole 24. The mounting portion 20, which is press-fitted by the movement of the molten lead, is soldered to the correct position without sliding.

It is preferable that the mounting portion 20 is configured to bend the metal plate in a " U "-shaped shape, and to have a bottom surface in a horizontal plane to effectively constitute a soldering surface.

Reference numeral 30 denotes a molten lead of the soldering portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

4 and 5, the press-fit terminal A of the present invention is continuously fed by a known automatic press apparatus not shown in the first substrate 100, The terminal A is soldered.

The press-fit terminal A according to the present invention supplied by this operation is accurately supplied to the upper portion of the molten lead of the first substrate 100 and is brought into close contact with the upper portion of the molten lead. Further, the wide surface of the mounting portion 20 is pressed onto the molten lead, Easy to work,

When the pressure is generated in the press-fit terminal A supplied while being pressurized by the automatic pressure-application device, elongation and contraction are generated in the elastic portion 15 formed at the lower portion of the switch portion 10 to prevent warping of the switch portion 10 The switching unit 10 which is moved up and down by such expansion and contraction freely moves by a predetermined distance by the slot 22 in the guide hole 22 of the mounting portion 20 to prevent the switching unit 10 from being bent or ruptured .

Also, in such a soldering operation, when the mounting portion 20 is guided to the upper portion of the molten solder,

That is, when the bonding surface 16 of the mounting portion 20 presses the molten lead 30, the molten lead 30 melts to the periphery of the through hole 24 through the through hole 24 opened to the outside and the center The press-fit terminal A for the connector of the present invention, which is press-fitted in the soldering operation, is vertically and accurately soldered without slip.

Since the molten lead 30 is wrapped around the bonding surface 16, the through hole 24, and the through hole 24 to the upper periphery thereof, the solder 30 exhibits a strong adhesive force after the soldering, The soldering portion of the press-fit terminal A of the present invention can be prevented from being broken even when the second substrate 110 fastened to the first substrate 100 is pressed.

As a result, the second substrate 110 is fastened to the upper side elastic pressure-contacting portion 12 of the press-fit terminal soldered to the first substrate 100.

That is, the second substrate 110 is supplied by a well-known method, and the pressing holes 101 formed in the second substrate 110 are aligned with the soldered press-fit terminal A, And the elastic pressure-contacting portion 12 is stretched and tightened to the correct position by engaging with the control jaw 13 on the main surface of the fastening hole 101 of the second substrate 110 which is inserted into the fastening hole 101 while being fastened.

In this operation, the switching unit 10 receiving the pressure generated by forcibly inserting the second substrate 110 is lowered by the pressure, and a pair of guide pieces 14 extended outward from the lower end side of the switching unit 10 And this movement is guided by the guide hole 23 in which the slot 22 which is the moving space is formed at the upper center of the control panel 21 and moves to the distance of the slot 22 vertically, , Warping, and the like.

The downward movement of the second substrate 110 is reduced by the expansion and contraction of the "⊂" or "S" -like elastic portion 15 extending in unity and reduced in width and thickness at the center of the switching portion 10, And is returned to the elasticity of the elastic portion 15 when it is mounted.

As a result, the first and second substrates 100 and 110 are fastened to each other. The fastening hole 101 for holding the elastic pressure-contacting portion 12 and the soldering portion are electrically connected to each other as is well known in the art.

The guide piece 14 of the switching portion 10 is guided in the guide hole 22 of the mounting portion 20 so as to be vertically slid so as to prevent the shake of the switching portion 10 at the time of insert operation on the PCB first substrate 100 The insert is accurately formed by suggesting the movement of the shaft, and since the mounting portion 20 is formed in a large area, the soldering area can be ensured and a firm fixing force can be obtained.

The elastic portion 15 in the present invention may be formed in a "⊂" shape or an "S" shape or the like so as to have a good stretchability, and it is natural that the elastic portion 15 can be formed in a different shape.

The elastic portion 15 prevents soldering from being broken with the PCB first substrate 100 due to the downward pressure of the switching portion 10 at the time of inserting the PCB second substrate 110.

The present invention is characterized in that the guide piece 14 is lifted up and down by the left and right guide holes 23 in which the slot 22 as the moving space is formed and the elastic part 15 connected to the mounting part 20 is moved from the switching part 10 It is possible to improve the disadvantages such as warping due to the eccentricity generated at the time of soldering.

While the present invention has been described with respect to preferred embodiments, it should be understood that various equivalents and modifications may be substituted for them. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims.
