Description

  The present invention relates to a press-fit terminal used in a solder-free connection method (press-fit method), a fixing method thereof, and a method for manufacturing a circuit board device using the press-fit terminal.

  Generally, in the press-fit method, a press-fit terminal with a base part made of phosphor bronze, etc., with a press-fit part with spring force, is press-fitted into the through-hole of a circuit board (rigid printed circuit board). Electrical and mechanical connections are made by spring reaction force (spring force) generated in the transverse direction perpendicular to the axis of the press-fit portion in the hole.

  Here, dozens of types of press-fit terminals are currently being developed, and in all of them, electrical and mechanical connections are made by utilizing a lateral spring force perpendicular to the axis. The maximum width of the press-fit portion provided with spring force is larger than the diameter of the through hole of the circuit board to be press-fitted. For this reason, the currently used method of inserting a press-fit terminal into a through-hole is a single press-fit terminal or a plurality of presses, regardless of whether the press-fit terminal is a single unit or a connector having a plurality of press-fit terminals. Attach the connector with the fit terminal to the jig of the load machine, fix the circuit board to the jig of the circuit board, lower the press fit terminal together with the load machine, and pass through the circuit board with a diameter smaller than the maximum width of the press fit part It is a method of press-fitting with force to the hall. At this time, the vertical position accuracy is determined by the accuracy of the jig and the downward position accuracy of the load machine.

  As prior literature regarding conventional press-fit terminals, there are those shown in Patent Documents 1 to 3.

Japanese Patent Laid-Open No. 06-013735 Japanese Patent Laid-Open No. 10-092999 JP-A-10-294564

  In such a press-fit terminal, since the press-fit terminal having a press-fit portion width larger than the through-hole diameter of the circuit board is mechanically press-fitted with a load machine, the surface plating of the press-fit portion is caused to pass through the circuit board. Rubbing at the edge of the hole caused plating scraping at the press fit. There is a problem in that the plating scraps removed by this plating scrap become conductive foreign matters, and when they come into contact with through holes or other patterns of adjacent circuit boards, a bridge is formed and the conductor patterns are short-circuited.

  The present invention has been made to solve the above-described problems, and relates to a press-fit terminal capable of suppressing plating scraping of a press-fit portion, a fixing method thereof, and a method of manufacturing a circuit board device using the press-fit terminal. It is.

  In order to achieve this object, in the present invention, a press-fit portion, a holding load portion provided at one end portion of the press-fit portion, a load receiving portion provided at the other end portion of the press-fit portion, and a load A displacement direction converting portion that converts the displacement of the holding load portion with respect to the receiving portion into a lateral displacement of the press fit portion and a displacement amount lock portion that maintains the lateral displacement of the press fit portion are provided.

  In the present invention, the axial displacement of the holding load portion due to the axial load is converted into the lateral displacement of the press fit portion, and the press fit portion is locked in a state where the press fit portion is displaced laterally. Therefore, rubbing of the press fit portion at the edge of the through hole does not occur, and plating scraping of the press fit portion in the press fit terminal can be suppressed.

First Embodiment FIG. 1 is a diagram showing a basic structure of a press-fit terminal according to the present invention. 1 is a press-fit terminal, 15 and 16 are two press-fit parts that are symmetrically arranged, 10 is a holding load part that is attached to a load machine and applies an axial load from the load machine to the press-fit parts 15 and 16, Reference numeral 20 denotes a load receiving portion that receives an axial load applied by a load machine by abutting the tip against a positioning jig.

  That is, the press-fit terminal 1 includes press-fit portions 15 and 16 disposed symmetrically with respect to the axis, a holding load portion 10 provided at one end of the press-fit portions 15 and 16, A load receiving portion 20 provided at the other end of 16, and a displacement direction converting portion that converts the displacement of the holding load portion 10 relative to the load receiving portion 20 into a lateral displacement perpendicular to the axis of the press fit portions 15, 16. , And a displacement amount lock portion that maintains the displacement in the lateral direction of the press fit portions 15 and 16.

  The displacement direction converting portion includes first and second inclined surfaces 61 and 62 provided on the load receiving portion inclined surface protrusion 22 extended on the axis from the load receiving portion 20 toward the holding load portion 10, and the press fit portion 15. 16 and the third and fourth inclined surfaces 63 and 64 provided on the press-fit portion protrusions 31 and 32 extended from the axial direction to the axial line side. The first and second locking claw portions 11 and 12 are provided, and the first and second locking claw stopper portions 41 and 42 are provided on the load receiving portion inclined surface protrusion 22.

  Here, the holding load portion 10 and the load receiving portion 20 are arranged on the same axis with a space, and the outer shape of the press fit portions 15 and 16 is more lateral than the width of the holding load portion 10 and the load receiving portion 20. It is overhanging.

  FIG. 2 is a diagram showing the relationship between the press-fit terminals and the circuit board. The press fit portions 15 and 16 are arranged so that the maximum outer shape portion (a dimension) is arranged on the load receiving portion 20 side, and the distance between the outer shapes of the press fit portions 15 and 16 becomes smaller toward the holding load portion 10 side. The outer shapes of the fit portions 15 and 16 are inclined at an inclination angle θ. Therefore, by making the maximum outer shape portion smaller than the diameter (b dimension) of the through hole 2, the press fit portions 15 and 16 can be inserted without contacting the peripheral wall of the through hole 2.

  FIG. 3 is a diagram showing details of the displacement direction conversion unit and the displacement amount lock unit. The first and second inclined surfaces 61 and 62 are formed in a shape that linearly expands from the distal end portion of the load receiving portion inclined surface protrusion 22 toward the base portion, and the third and fourth inclined surfaces 63 and 64 are formed. The first and second inclined surfaces 61 and 62 have the same inclination angle and the same inclination direction, and at least partially overlap with the first and second inclined surfaces 61 and 62 in the direction parallel to the axis. It is. Further, the first and second locking claws 11 and 12 are connected to the end surfaces of the first and second press-fit portion projections 31 and 32 on the holding load portion side and the third and fourth inclined surfaces 63 and 64. Consists of convex portions formed at the intersections, and the first and second locking pawl portions 41, 42 are arranged on the inclined surface that is the maximum lateral width of the first and second inclined surfaces 61, 62. The width (e dimension) of the large portion is formed wider than the width (d dimension) of the load receiving portion inclined surface protrusion 22 and is formed by a step portion between the e dimension and the d dimension.

  The lateral distance (c dimension) between the first and second locking claw portions 11 and 12 depends on the axial load, and the first and second inclined surfaces 61 and 62 and the third and fourth inclined surfaces 63. , 64 slides and expands as they are relatively displaced, and after passing through the e dimension, they are locked by the first and second locking pawls 41 and 42, and even if the axial load is eliminated, the d dimension position is maintained. Maintained in a displaced state. For this reason, the press fit portions 15 and 16 are also displaced in the lateral direction by an amount corresponding to the difference between the d dimension and the c dimension. Therefore, by adjusting the c dimension and the d dimension between the first and second locking claw parts 11 and 12, the first and second locking claw parts 11 and 12 at the time of locking can be It is possible to arbitrarily determine the distance between the outer shapes of the press-fit portions 15 and 16 that are locked to the locking pawl portions 41 and 42. As a result, the contact pressure applied to the peripheral wall of the through hole 2 by the press fit portions 15 and 16 can be adjusted.

  In this case, the outer shape of the press-fit portions 15 and 16 in a state where the first and second locking claw portions 11 and 12 are locked to the first and second locking claw portions 41 and 42 is as follows. Between the maximum outer shape portion and the first and second press-fit portion protrusions 31 and 32, it is parallel to the axis.

  That is, by fixing the load receiving portion 20 and applying a load in the axial direction from the holding load portion 10, the first and second press-fit portion protrusions 31 and 32 are displaced downwardly by the first and second inclined surfaces 61. , 62 is converted into a lateral displacement perpendicular to the axis, and the press-fit portions 15, 16 are also displaced laterally perpendicular to the axis. For this reason, the press-fit terminal 1 can be fixed to the through hole 2 with a predetermined contact pressure after being inserted into the through hole 2. The press-fit portions 15 and 16 are determined in shape and size so as to be deformed by a predetermined amount in a lateral direction perpendicular to the axial line by a predetermined axial force.

  Next, the use method of the press-fit terminal in the present embodiment, that is, the fixing method to the through hole and the method of manufacturing the circuit board device using the press-fit terminal in the present embodiment will be described with reference to FIG.

  First, in FIG. 4A, the holding load portion 10 of the press-fit terminal 1 is attached to the load machine 4. On the other hand, the through hole 2 of the circuit board 3 is aligned with a predetermined position of the board holding jig 5 to fix the circuit board 3 to the board holding jig 5.

  Next, in FIG. 4B, the press-fit terminal 1 attached to the load machine 4 is gradually lowered while being attached to the load machine 4 and inserted into the through hole 2. Since the maximum outer shape (a dimension) of the press fit portions 15 and 16 is smaller than the b dimension which is the inner diameter of the through hole 2, the press fit terminal 1 is not brought into contact with the peripheral wall of the through hole 2. Can be inserted into.

  In FIG. 4C, the press-fit terminal 1 attached to the load machine 4 is further lowered, and the load receiving portion 20 is abutted against the substrate holding jig 5. At this position, the press-fit terminal 1 is fixed to the through hole 2.

  In FIG. 4D, an axial (downward) load is applied to the press-fit terminal 1 in a state where the load receiving unit 20 is abutted against the substrate holding jig 5 with the load machine 4. The first and second press-fit projections 31 and 32 are pushed downward by the axial load, slide along the first and second inclined surfaces 61 and 62, and the downward displacement is converted into a lateral displacement. The first and second press-fit portion protrusions 31 and 32 are displaced in the lateral direction, and the press-fit portions 15 and 16 are also displaced in the lateral direction. The lateral displacement amount of the press-fit portions 15 and 16 is large at the first and second press-fit portion protrusions 31 and 32 positions, and is small at the maximum outer shape portion position. For this reason, the overall outer shape of the press-fit portions 15 and 16 is parallel to the axis between the maximum outer-shape portion position and the first and second press-fit portion protrusions 31 and 32 positions, with a predetermined contact pressure. It is fixed to the peripheral wall of the through hole 2.

  In FIG. 4 (e), when a load is further applied to the press-fit terminal 1 by the loader 4, the first and second locking claws 11 and 12 get over the inclined surface maximum width portion, and the first and second The locking claw portions 11 and 12 are locked by the first and second locking claw stopper portions 41 and 42. As a result, the press-fit portions 15 and 16 are in contact with each other on a plane parallel to the peripheral wall of the through hole 2 and are maintained in contact with each other. The press-fit terminal 1 is fixed to the circuit board 3 by the above procedure.

  Finally, the circuit board 3 after the press-fit terminal 1 is fixed to the circuit board 3 in FIG. 4F is removed from the board holding jig 5 and the press-fit terminal 1 is removed from the loader 4.

  As described above, in the method for fixing the press-fit terminal 1 to the through-hole 2 in the present embodiment and the method for manufacturing the circuit board device in which the press-fit terminal 1 in the present embodiment is fixed to the through-hole 2. , Press fit portions 15, 16 arranged symmetrically with respect to the axis, holding load portion 10 provided at one end of press fit portions 15, 16, and provided at the other end of press fit portions 15, 16 The received load receiving portion 20, the displacement direction converting portion that converts the displacement of the holding load portion 10 relative to the load receiving portion 20 into a lateral displacement perpendicular to the axis of the press fit portions 15, 16, and the press fit portions 15, 16. The press-fit terminal 1 having a displacement amount lock portion that maintains the displacement in the lateral direction is inserted into the through hole 2, and the load receiving portion 20 is received by the positioning jig 5, By applying a load in the axial direction to the holding load portion 10 by the heavy machinery 4, the press fit portions 15, 16 can be displaced in the lateral direction, and the press fit portions 15, 16 can be brought into contact with the peripheral wall of the through hole 2, The press-fit terminal 1 can be fixed to the through hole 2 of the circuit board 3, and a circuit board device in which the press-fit terminal 1 is fixed to the through hole 2 can be manufactured.

  For this reason, in the attachment to the circuit board 3, the effect which prevents peeling of the plating of the press fit parts 15 and 16 of the press fit terminal 1 is acquired. Further, the following effects can be obtained. That is, it is possible to prevent plating scraping of the through-hole 2 caused by the press-fit terminal 1 rubbing against the peripheral wall of the through-hole 2, and disconnection at the contact surface between the press-fit terminal 1 and the through-hole 2, partially missing, or scraped plating. The problem that scraps become conductive foreign matters and come into contact with other patterns, bridges are formed, and the conductor patterns are short-circuited is solved. Further, the problem that the press-fit terminal 1 is rubbed with the side surface of the through hole 2 and the through hole 2 and the inner layer of the circuit board 3 are damaged to cause deformation and disconnection can be solved. Further, conventionally, the press-fit terminal 1 is shaped so that the portion that comes into contact with the through-hole 2 to be inserted has a maximum outer shape so as not to cause plating peeling or damage during press-fitting, and gradually increases toward this position. The shape was rounded. For this reason, there is a problem that the contact pressure area between the press-fit terminal 1 and the through hole 2 is limited to a part of the maximum outer shape, and the allowable current to the inner layer of the circuit board 3 is limited and cannot be used with a large current of the power supply system. However, if the outer shape of the press-fit portions 17 and 18 is made parallel to the axis, the contact pressure area between the press-fit terminal 1 and the through-hole 2 can be increased and eliminated. Further, there is an effect that the contact pressure between the press-fit terminal 1 and the peripheral wall of the through-hole 2 can be adjusted by controlling the c dimension and the d dimension without changing the diameter of the through-hole 2 and the width of the press-fit terminal 1.
