Description

[0001] ELECTRICAL CONNECTOR AND TERMINAL [0002]

The present invention relates to an electrical connector and a terminal in which one terminal has two contact portions in the connection direction with respect to a relative connector.

An electric connector in which two contact portions are formed on one terminal in the connection direction toward the counterpart connector is known as, for example, Patent Document 1, in order to improve contact (connection) reliability with the counterpart connector.

The terminal in the electrical connector of Patent Document 1 is manufactured so that the metal plate in the band is bent and bent so that the connecting direction becomes the terminal length direction and has two elastic arm portions. The two elastic arm portions all extend in the longitudinal direction of the terminal, and the bases are connected to each other with a part of them as a base, and the contact portion bent at the tip end. As shown in FIGS. 4 and 8 of Patent Document 1, the two elastic arm portions are bent so as to overlap each other at the base portion, whereby the two elastic arm portions can be elastically bendable independently from each other, Are arranged at the same positions in the terminal arrangement direction, and the mutual contact portions are formed at different positions in the terminal longitudinal direction. Thus, when the mating terminal, for example, the mating terminal on the pin moves in the connecting direction toward the terminal, the mating terminal comes into contact with the two contacting portions with a time lag and has two contact points, .

Japanese Laid-Open Patent Publication No. 2016-173998

However, in Patent Document 1, the contact portions of the two elastic arm portions are formed so that the contact points formed by vertexes bent in a mountain-like shape are located at different positions in the terminal longitudinal direction. However, since the two elastic arms are positioned at the same position in the terminal arrangement direction by the overlapping bending at the base, when one of the elastic arms causes elastic bending, a part of one of the elastic arms is engaged with the other elastic arm Which is in contact with the negative contact portion.

Therefore, at the time when the one-side elastic arm portion generates a limited amount of warpage even when it bends under the contact pressure between the contact portion and the mating terminal, it interferes with the other contact portion and the warpage does not increase further, It can not be largely secured. This means that a sufficiently large contact pressure with the mating terminal can not be obtained.

Further, in Patent Document 1, in order to reduce the terminal (width) dimension in the array direction of the plurality of terminals, as described above, the two elastic arms are bent 180 degrees so as to overlap each other So that they are formed at the same position in the terminal arrangement direction. Therefore, the degree of bending at the bending edge of the base portion is very large, and the strength of the terminal at the bending edge is lowered.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a connector which can secure the strength of a terminal while suppressing the terminal width dimension in the terminal arrangement direction as much as possible, and that the contact portions of the two elastic arms do not interfere with each other in the elastic bending state, That is, an electrical connector having terminals capable of ensuring sufficient contact pressure with a relative connector and a terminal.

In the electrical connector and the terminal for the electrical connector according to the invention, a plurality of arrangements are held by the housing with respect to the direction in which the terminals, which make the connection direction with respect to the relative connection member, in the terminal longitudinal direction are perpendicular to the terminal longitudinal direction .

In such an electrical connector and terminal, the terminal has a first resilient arm portion and a second resilient arm portion formed as a bent metal plate single member and adjacently arranged in the terminal arrangement direction, and the first resilient arm portion The first base portion and the second base portion of the second elastic arm portion form base portions connected to each other in a bent state perpendicular to each other at right angles to each other in the direction perpendicular to the plate thickness direction,

And a mounting portion for mounting the conductive rods in the other direction which is opposite to the first elastic arm portion and the second elastic arm portion with respect to the base portion,

The first elastic arm portion includes a first straight portion extending from the first base portion in one direction in the longitudinal direction of the terminal and a second straight portion extending from the first straight portion in the one direction to a free end, Wherein the first contact portion for contacting and the rolling surface of the first base portion, the first straight upper portion and the first contact portion are parallel to the terminal arrangement direction,

The second resilient arm portion has a second straight upper portion extending from the second base portion toward the one direction from the first straight upper portion in the longitudinal direction of the terminal and a second straight upper portion extending from the second straight portion toward the terminal arrangement direction, And a second contact portion bent in the thickness direction and bent in the thickness direction toward the terminal longitudinal direction and positioned on the side of the first contact portion in the one direction, wherein the first contact portion and the second contact portion are also provided on the rolled plate surface, And the second contact portion is passed through the second contact portion having a positional relationship with the first contact portion so that the relative contact member is in contact with the first contact portion after the contact with the second contact portion due to the movement in the connection direction The straight line in the connecting direction passes through the first contact portion.

According to the present invention having such a constitution, since the base portions of the first base portion and the second base portion are bent at right angles, the terminal width (terminal arrangement direction dimension) It is possible to suppress the plate thickness of the two elastic arms to the sum of the thicknesses thereof, which is not much larger than that of the conventional terminal.

The first contact portion and the second contact portion are located at positions overlapping the terminal widths of the counterparts in the terminal arrangement direction but at different positions in the longitudinal direction of the terminals and portions other than the first contact portion and the second contact portion Since they are at different positions in the terminal arrangement direction, they do not interfere with each other in the elastic bending state. Therefore, the first contact portion and the second contact portion can be made large without any restriction, and as a result, a large contact pressure with the counterpart connection can be secured.

In both of the first contact portion and the second contact portion, since the rolled plate surface is the contact surface with the counterpart contact, the contact width with the counterpart contact and thus the contact area becomes larger and the contact becomes smooth.

In the present invention, the second contact portion of the second resilient arm portion may be oriented in the one direction in which the free end thereof is in a direction away from the first contact portion of the first resilient arm portion in the terminal longitudinal direction.

By doing so, in the plane shape before bending the terminal material, the portion constituting the second abutment portion of the second elastic arm portion is bent in the direction perpendicular to the terminal longitudinal direction (terminal arrangement direction) with respect to the portion constituting the second straight- And as a result, the dimension of the terminal material in the terminal longitudinal direction is suppressed. Since the yield of the material of the terminal material is dependent on the dimension in the terminal longitudinal direction, the second contact portion extends not in the terminal longitudinal direction but in a direction perpendicular to the terminal longitudinal direction, thereby improving the yield, Since the portion constituting the second contact portion is located on the side of the region where the elastic arm extends in the longitudinal direction of the terminal, there is a margin of space for the second contact portion originally, So that the terminal material does not need to be extra for the second contact portion even in the perpendicular direction.

Both of the first contact portion and the second contact portion can be brought into contact with the contact surface of the one side of the terminal material with respect to the counterpart connector. Since the terminal material is usually shaped by punching, "sagging" occurs on the punching edge and "burr" occurs on the other side above the rolled surface of the front and rear sides. Therefore, according to the above-described aspect, since the contact surface of the first contact portion and the second contact portion to the relative connection member can be positioned on the surface of the one surface on which the "sagging" is formed, So that smooth contact can be achieved.

On the other hand, with respect to the above-described embodiment, the second contact portion of the second resilient arm portion is designed so that the free end thereof is directed to the other direction that is the direction close to the first contact portion of the first elastic arm portion in the terminal longitudinal direction It is possible.

With this configuration, since the tip of the second contact portion (the portion that first starts contact with the counterpart body) that comes into contact with the counterpart connector before the first contact portion forms a convex curve, the leading edge does not collide with the counterpart It is ensured and smoothly guided by the convex curved surface of the relative connector.

In the present invention, it is preferable that a reinforcing rib is formed on at least a second base portion of the first base portion of the first elastic arm portion and the second base portion of the second elastic arm portion. When the ribs are formed at least on the second base portion, the second base portion and thus the entire base portion are reinforced. When the ribs are formed so as to protrude from the outer surface in the terminal arrangement direction, , And the holding strength thereof is improved.

In the present invention, as described above, the first base portion of the first elastic arm portion of the terminal and the second base portion of the second elastic arm portion are bent so that the rolled plate surfaces of the material of the first elastic arm portion and the second elastic arm portion are perpendicular to each other, And the second elastic arm is formed so as to extend from the second base portion in the longitudinal direction of the terminal to the side of the first straight portion from the first straight portion in the one direction And a second straight upper portion extending from the front end of the second straight upper portion toward the terminal arrangement direction and bent in the plate thickness direction and bent in the plate thickness direction toward the terminal longitudinal direction, The first contact portion and the second contact portion are formed so as to be in contact with the counterpart contact on the rolled plate surface, The second contact portion has a positional relationship with respect to the first contact portion so as to be in contact with the first contact portion after the contact with the second contact portion due to the movement in the direction of the first contact portion, The strength of both base portions is improved by bending rather than causing a local decrease in strength at the bending edge so that the dimension of the terminal in the terminal arrangement direction can be adjusted by changing the width of the first base portion to the thickness of the second base portion And the second straight portion is shifted from the terminal arrangement direction with respect to the first straight upper portion and the second contact portion is located on the side of the terminal in the longitudinal direction of the terminal with respect to the first contact portion , It does not interfere with the first contact portion in the elastic bending state of the second resilient arm portion, so that the sufficient bending amount, that is, the contact pressure with the counterpart contact .

The connector I comprises a housing 10 made of an electrically insulating material and a shield case 20 made of a metal plate fitted to the housing 10 and a terminal holding body 30 made of an electrically insulating material inserted in the housing 10, And a terminal 40 made of a metal plate held by the terminal holding body 30. Fig. 2 is a perspective view showing a state in which these various members are separated before assembly. Fig. 3 is a cross-sectional view of the connector I after being assembled, together with its mating connector II, before the mating connector II as a mating connector is connected.

Since the present invention is characterized by the terminal 40, the description starting from this terminal 40 is started. As shown in Fig. 2, the terminal 40 has two types of terminals 40A and 40B, which have the same main portion and differ only in the length of the connecting portion formed at the rear end (the end in the direction away from the mating connector II) (40B). The description of the terminal 40A will be omitted by attaching B to the terminal 40B in place of A in the reference numerals used in the description of the terminal 40A. The two types of terminals 40A and 40B are arranged alternately and integrally molded and held by the terminal holding body 30. The terminal holding body 30 is held in contact with the housing 10 Two types of terminals 40A and 40B held by the two terminal holding bodies 30 are assembled in such a manner that the two terminal holding bodies 30 constitute upper and lower two stages in an inverted posture, When the two terminal holding bodies 30 are assembled to the housing 10 (the terminals 40B are arranged in the connector height direction Z of the terminals 40A) in the arrangement direction Y, The terminals 40A and 40B as a whole are arranged in a zigzag manner.

The terminal 40A and the terminal 40B are all made of a metal plate and the direction of connection with the mating connector II as a counterpart connector (see Fig. 3) is the terminal longitudinal direction X, One of the two directions at right angles to the terminal arrangement direction Y is set in the terminal arrangement direction Y and the other is set in the connector height direction Z (the upper and lower directions of the two vertically positioned terminal holding members 30) The terminal body 40A and the terminal 40B are alternately arranged in the terminal arrangement direction Y. [

The terminal holding bodies 30 holding and holding the terminals 40A and 40B in an alternate manner are arranged in two stages in the height direction Z of the connector and are symmetrical with each other in the connector height direction Z Two terminal holding bodies 30 are mounted and held in one common housing 10 in a pair. As a result, the two types of terminals 40A and 40B arranged in two stages are alternately arranged in a staggered state in a state of being held by the housing 10, as described above.

2, two kinds of terminals 40A and 40B are alternately arranged in the terminal arrangement direction in each of the two-stage terminal holding bodies 30, but the upper and lower ends The terminals 40A and 40B are shown in a separated state before they are held by the terminal holding body 30. [ As described above, since the two-stage terminal holders 30 are arranged in an up-and-down symmetrical posture with respect to each other, the terminals 40A and 40B which are shown separately are symmetrical in the vertical direction, .

One terminal 40A of the two types of terminals 40A and 40B having different lengths of connecting portions and having the same shape is described. The terminal 40A is formed on the rolled plate surface of the terminal material (metal plate) A base portion 41A bent in a right angle with respect to the base portion 41A forming an L-shaped phase has a first base portion 41A-1 and a second base portion 41A-2 perpendicular to each other (see Fig. The terminal 40A includes a first elastic arm portion 42A extending from the first base portion 41A-1 in one direction in the terminal longitudinal direction X and a second elastic arm portion 42B extending from the second base portion 41A- A second elastic arm portion 43A that is independent of the arm portion 42A and extends in one direction in the terminal longitudinal direction X as the first elastic arm portion 42A and a second resilient arm portion 43A that is independent of the arm portion 42A, And a mounting portion 44A located in the other direction in the X direction. On the other hand, as described above, the other terminal 40B is arranged such that the mounting portion 44B of the terminal 40B is longer than the mounting portion 44A of the terminal 40A in comparison with the terminal 40A The connecting portion 45B of the terminal 40B has a larger step in the connector height direction Z than the connecting portion 45A of the terminal 40A as described later (However, in Fig. 2, the posture is shown in a vertically inverted posture because the posture is symmetrical in the up-and-down direction). As described above, the other terminal 40B is different from the terminal 40A in that it is set longer than the mounting portion 44A of the one terminal 40A in the terminal longitudinal direction Hereinafter, the shape of one of the terminals 40A will be described in detail, and the description of the other terminal 40B different from the mounting portion 44B will be omitted.

The first contact portion 42A-2 is formed as a mountain-shaped portion bent toward the free end with respect to the inclined arm portion 42A-3 so as to be inclined downward in Fig. 4 (A). And the apex of the mountain-shaped portion forms a contact with the counterpart connector. The first straight upper portion 42A-1 and the first contact portion 42A-2 are not bent in the terminal arrangement direction Y and are straight in the terminal longitudinal direction X when viewed from above And the upper surface of the first straight upper portion 42A-1 and the first contact portion 42A-2 are formed of the same rolled plate surface as the first base portion 41A-1. That is, the same rolled surface is directed upward in the entire range from the first base portion 41A-1 to the first contact portion 42A-2.

The first base portion 41A-1 has a flat plate shape in which the rolled plate surface is located in a plane extending in the terminal longitudinal direction X and the terminal arrangement direction Y, Side protruding portion 41A-1-1 protruding toward the second elastic arm portion 43A described below is formed.

The two-step bent portion 43A-3 is formed to be wider than the width of the tip end of the first elastic arm portion, is bent at a right angle with respect to the rolled plate surface of the second straight upper portion 43A-1, Y is directed toward the first elastic arm portion 42A and then the upper edge side thereof is bent with respect to the rolled plate surface so as to be inclined toward one direction of the terminal longitudinal direction X to be brought into contact with the second contact portion 43A- . The second contact portion 43A-2 extends from the upper edge of the two-step bent portion 43A-3 and extends in the same direction as the first contact portion 42A-2 of the first elastic arm portion 42A, Is bent toward one direction of the direction X and extends from the one direction to the free end. The second contact portion 43A-2 has the same mountain shape as the first contact portion 42A-2, and its apex forms a contact with the counterpart contact. As a result of the bending of the second base portion 41A-2 and the second bending portion 43A-3, the second contact portion 43A-2 is rolled on the same side as the first contact portion 42A- And is formed as a flat surface. The second contact portion 43A-2 is located at substantially the same position as the first contact portion 42A-2 in the terminal arrangement direction Y and in the connector height direction Z, the second contact portion 43A- -2 and the apex of the first contact portion 42A-2. In other words, the relative connection member having the terminal longitudinal direction X as the connection direction is in contact with the second contact portion 43A-2 in the connecting process, and then the first contact portion 42A- 2). In this embodiment, the terminal width (dimension width in the terminal arrangement direction Y) of the second contact portion 43A-2 is set so as to be substantially the same position as the first contact portion 42A-2 in the terminal arrangement direction Y However, the present invention is not limited to this.
