Description

Connector

The invention relates to a connector.

Generally, a pair of parallel circuit boards have been electrically connected together using connectors such as a board-to-board connector. However, deviations may occur in the relative positions of a plurality of predetermined circuit boards. Therefore, in order to absorb the positional deviation of a plurality of circuit boards, a connector having a floating structure has been proposed (see, for example, Patent Document 1).

Fig. 15 is a sectional view of a conventional connector.

In the figure, 801 represents a floating-type first connector mounted on a first circuit substrate 891, and 901 represents a second connector mounted on a second circuit substrate 991 as a mating connector. The first connector 801 is provided with a fixed base 811 fixed to the first circuit substrate 891, a movable base 821 provided to freely move toward the inside of the fixed base 811, and a plurality of first terminals 851.

The first terminal 851 is provided with a tail portion 852 mounted on the fixed base 811 and fixed on the first circuit substrate 891, a contact portion 854 mounted on the movable base 821, and an elastic portion 855 connecting the tail portion 852 and the contact portion 854. In addition, when the second connector 901 moves as shown by an arrow in the figure to be docked with the first connector 801, a second terminal 951 provided by the second connector 901 is held by the forked contact portion 854 and is in contact with the first The terminal 851 is electrically connected. In addition, the elastic portion 855 is elastically deformed, and thus the movable base 821 is moved relative to the fixed base 811, and the movable base 821 is maintained in a floating state relative to the fixed base 811.

However, in the conventional connector, the elastic portion 855 of the first terminal 851 is simply bent into a U shape, and therefore, the length of the elastically deformable portion is insufficient, and thus the flexibility of the first terminal 851 is insufficient. Therefore, the movable base 821 cannot move flexibly with respect to the fixed base 811, and the positional deviation between the first circuit substrate 891 and the second circuit substrate 991 cannot be appropriately absorbed.

In addition, in order to increase the flexibility of the first terminal 851, when the elastically deformable portion in the elastic portion 855 is lengthened, the height of the first connector 801 increases, and therefore, between the first circuit substrate 891 and the second circuit substrate 991 The spacing cannot be reduced.

In this article, in order to solve the problem of conventional connectors, an object is to provide a connector with low height, high flexibility, reliably maintaining a docking state, and high reliability without being damaged.

Further, in another connector, the stopper portion is formed by a through hole formed in the side wall portion and a protrusion inserted into the through hole protruding outward from the inner base in a width direction. The amount of relative movement between the inner base and the outer base is limited by a size of a gap between an inner peripheral surface of the through hole and an outer peripheral surface of the protrusion.

In addition, in another connector, the deformed portion further includes: a connecting portion bent so that the front end faces the forward direction; a first U-shaped turning portion, wherein the base end is connected to the front end of the connecting portion and a middle portion The ground is bent and U-turned so that the front end faces the rear direction; a second U-turned part where the base end is connected to the lower or upper end of the inner mounting part and a middle part is bent and U-turned so that the front end faces A front direction; and a crank portion connecting a front end of the first U-turn portion and a front end of the second U-turn portion.

The contact portion 54 includes a connection portion 54 a connected near the lower end of the inner mounting portion 56 and a thick plate portion 54 c protruding from the connection portion 54 a in the forward direction. The entire first terminal 51 is a part formed by punching a single thin metal plate, but the portion of the contact portion 54 that contacts the second terminal 151 as a mating terminal must be thick. Therefore, by The plate is folded into two layers to form a thick plate portion 54c having a thick wall. Note that the upper end of the thick plate portion 54c is a bent portion 54b formed when a single thin metal plate is folded. In addition, the contact portion 54 projects in a forward direction from the pair of abutment surfaces 23f, and the abutment surface 23f is a front surface of the front wall portion 23 of the inner base 21.

The deformed portion 55 is a part of the outer mounting portion 53, the inner mounting portion 56, and the like, and is a portion formed with the same thickness but a narrow width, and provides flexibility capable of being elastically deformed in a three-dimensional direction. Accordingly, the outer mounting portion 53 and the inner mounting portion 56 are connected in a three-dimensional direction in a deformable manner, and therefore, the outer base 11 and the inner base 21 are connected in a three-dimensional direction in a deformable manner. In addition, the deformed portion 55 is provided with a connecting portion 55b having a substantially L-shaped side shape, which protrudes in an entire vertical direction as a whole and is bent so that the base end 55a is connected to the lower end of the outer mounting portion 53 The front end faces forward; a first U-turn portion 55c has a substantially J-shaped side shape, in which the base end is connected to a front end of the connecting portion 55b and the middle portion is bent substantially and the U-turn makes the first The front end of the U-turn portion 55c faces the rear direction; a second U-turn portion 55e has a substantially J-shaped side shape, wherein the base end 55f is connected to the lower end of the inner mounting portion 56 and the middle portion is bent and U The U-turn makes the front end of the second U-turn portion 55e face forward; and a crank portion 55d having a crank-like side shape that connects the front end of the first U-turn portion 55c and the second U-turn portion 55e. Front end.

Therefore, the deformed portion 55 connects the first U-turn portion 55c and the second U-turn portion 55e through the crank portion 55d. Therefore, the length of a flexible elastically deformed portion having a narrow width is sufficiently long, and the deformed portion can be in a three-dimensional direction. The upper is flexibly and elastically deformed. In addition, the first U-turn portion 55c and the second U-turn portion 55e are connected by the crank portion 55d, so that the size of the entire deformed portion 55 in the front-rear direction and the height direction can be suppressed, and therefore, the first connector 1 The size and height can be reduced.

In addition, both ends of the deformed portion 55 are connected to the lower end of the outer mounting portion 53 and the lower end of the inner mounting portion 56, and therefore the size of the entire first terminal 51 in the height direction can be suppressed, and therefore, the height of the first connector Can reduce. Here, an example in which both ends of the deformed portion 55 are connected to the lower end of the outer mounting portion 53 and the lower end of the inner mounting portion 56 is described. However, both ends of the deformed portion 55 may be connected to the upper end of the outer mounting portion 53 and the inner mounting portion. The upper end of 56. In other words, both ends of the deformed portion 55 may be connected to both ends of the same side of the outer mounting portion 53 and the inner mounting portion 56.

Note that, as shown in FIG. 6B, in a side view, the upper end 53 c of the mounting protrusion 53 a of the outer mounting portion 53, the upper end 56 c of the mounting protrusion 56 a of the inner mounting portion 56, and the upper side 54 e of the contact portion 54 are at a height. Have substantially the same position in the direction, and the position of the first U-turn portion 55c of the deformation portion 55 in the height direction is substantially the same as or lower than the position of the upper end 56c and the upper side 54e in the height direction Position in the direction.

The second connector 101 is provided with a second base 111 and a plurality of second terminals 151 installed in the second base 111. A predetermined number (10 in the example shown in the figure) of the second terminals 151 are arranged at a predetermined pitch to form a first extending in the width direction (up and down direction in FIG. 3A) of the second connector 101. row.

The second base 111 is a component integrally formed of an insulating material (such as synthetic resin), has a substantially inverted C shape in a plan view, and includes a front wall portion 113 along the width direction of the second connector 101. Extending; and left and right side wall portions 112 extending from both ends of the front wall portion 113 in a rearward direction (leftward direction in FIG. 3A). The second nail 181 serving as a mounting auxiliary metal fixing device is mounted on a mounting recessed portion 112 d formed on the outer surface of the side wall portion 112. The second nail 181 is fixed to a connection pad or the like on a surface of the second substrate by welding. In addition, an upper surface (upper side in FIG. 3B) of the front wall portion 113 is a mounting surface 113a opposite to a surface of the second substrate, and a fixing protrusion 113b inserted into a mounting hole of the second substrate is mounted from The surface 113a protrudes.

The second base 111 is a part fixedly mounted on the surface of the second substrate, similar to the surface of the first base 1 where the outer base 11 of the first connector 1 is fixedly mounted, but in the example shown, the first substrate It is located on the lower side of the outer base 11 of the first connector 1, and the second substrate is located on the upper side of the second base 111. In other words, in the illustrated example, the first connector 1 and the second connector 101 which are butted to each other are mounted on the upper surface of the first substrate and the lower surface of the second substrate, respectively, so as to deviate in an up-down direction. The first substrate and the second substrate are electrically connected in a substantially parallel manner.

Note that the second connector 101 can be reversed up and down if necessary. In this case, the first connector 1 and the second connector 101 that are butted to each other are electrically connected to the first substrate and the second substrate that are disposed substantially on the same plane.

A receiving space 114 defined by the front wall portion 113 and the left and right side wall portions 112 exists in the rearward direction of the front wall portion 113, and a tail portion 152 of the second terminal 151 is aligned and received in the receiving space 114. In addition, the front wall portion 113 is provided with a plurality of terminal accommodation spaces 124. The terminal receiving spaces 124 are arranged with the same number and the same pitch as the second terminals 151 to form a row extending in the width direction of the second connector 101. It is noted that the terminal receiving space 124 is opened on the pair of abutting surfaces 113f, the abutting surface 113f is a front surface of the front wall portion 113, and the terminal receiving space 124 receives a contact portion 154 of the second terminal 151. In addition, in the terminal accommodation space 124, when the first connector 1 and the second connector 101 are docked, the contact portion 54 of the first terminal 51 corresponding to the second terminal 151 travels and the contact portion 154 of the second terminal 151 Electrical connection.

The second terminal 151 is a component integrally formed by processing a conductive metal plate such as punching and bending, and as shown in FIGS. 5A to 6B, it is provided with: a mounting portion 153, which is mounted on the second base 111; The tail portion 152 extends from the mounting portion 153 in a backward direction (leftward direction in FIG. 6A); the contact portion 154 extends from the mounting portion 153 in a forward direction (rightward direction in FIG. 6A); and the connecting portion 155 connects Mounting portion 153 and tail portion 152.

The tail portion 152 protrudes in a backward direction from the front wall portion 113 of the second base 111 and is connected to a connection pad or a conductive trace on a surface of the second substrate by welding or the like.

The contact portion 154 is a fork-shaped member that is bifurcated as a whole in a plan view, and includes: left and right arm portions 154a capable of being elastically deformed; a pair of terminal insertion spaces 154b between the left and right arm portions 154a; and a contact protrusion 154c, The arm portion 154 a formed at the front end of the arm portion 154 a and protruding toward the opposite side. When the first connector 1 and the second connector 101 are docked, the thick plate portion 54c on the contact portion 54 of the first terminal 51 enters the docking terminal insertion space 154b between the left and right arm portions 154a. As shown in the figure, one front end of the thick plate portion 54c is formed into a tapered shape, and one front end side of the contact protrusion 154c is also formed into a tapered shape, and therefore, the thick plate portion 54c smoothly travels between the left and right arm portions 154a.

In addition, the arm portion 154a elastically displaced by the traveling thick plate portion 54c exhibits an elastic force, and the left and right contact protrusions 154c hold the thick plate portion 54c from both sides by the elastic force and contact to bite two of the thick plate portion 54c. The surface, and therefore, the contact state between the contact protrusion 154c and the thick plate portion 54c is reliable, and therefore, the contact state between the second terminal 151 and the first terminal 51 is reliable. In addition, the thick plate portion 54c is a portion in which the aforementioned single metal plate is folded into two layers so as to be thicker than the single metal plate, and the displacement amount of the arm portion 154a is larger than in the case where a single metal plate is used. As a result, the elastic force exhibited by the arm portion 154a increases, and therefore, the contact state between the contact protrusion 154c and the thick plate portion 54c is more reliable. In addition, the thick plate portion 54c is thick, and therefore, even if the contact protrusion 154c vibrates relative to the thick plate portion 54c, for example, the durability is still high, and the contact state between the contact protrusion 154c and the thick plate portion 54c is not bad.

The mounting portion 153 is firmly mounted on the second base 111 by being docked in the mounting hole 113c. The mounting hole 113c is formed in the front wall portion 113, is opened on a rear surface of the front wall portion 113, and communicates with the terminal accommodation space 124. Note that a protrusion 153 a that bites into the wall surface of the mounting hole 113 c is formed on the side of the mounting portion 153.

Note that, as shown in FIG. 2A, the mounting holes 113c are provided in the width direction of the second connector 101, so that the positions alternate with the thickness direction of the second connector 101 (the up-down direction in FIG. 3B). Therefore, the contact portion 154 accommodated in the terminal accommodation space 124 also alternates its position up and down in the thickness direction of the second connector 101. on the other hand,

All the tail portions 152 have the same positions with respect to the thickness direction of the second connector 101. Therefore, two types of contact portions 155 are prepared for the second terminal 151, namely, a long contact portion and a short contact portion.

The configuration of the first connector 1 will be described in detail below.

7A and 7B are a pair of perspective views viewed from above the first connector of this embodiment; FIGS. 8A and 8B are a pair of perspective views viewed from below of the first connector of this embodiment; and FIG. 9A And FIG. 9B is a two-side view of the first connector in this embodiment; FIGS. 10A and 10B are a pair of perspective views viewed from above the inner base of the first connector in this embodiment; and FIG. 11A and FIG. 11B is a pair of perspective views viewed from above the outer base of the first connector of the present embodiment. Note that in FIGS. 7A to 8B, FIGS. 7A and 8A are a pair of views viewed from the front and FIGS. 7B and 8B are a pair of views viewed from the rear; in FIG. 9, FIG. 9A is A plan view and FIG. 9B are a side view; and in FIGS. 10A to 11B, FIGS. 10A and 11A are a pair of views viewed from the front and FIGS. 10B and 11B are a pair of views viewed from the rear.

As shown in the figure, a pair of left and right guide rod portions 25 extend in a forward direction from the abutting surface 23f, and the abutting surface 23f is the front of the front wall portion 23 on the inner base 21. When the first connector 1 and the second connector 101 are docked, the guide rod portion 25 is a member inserted into a guide hole 128 formed in the second base 111 described later, and thus the inner base 21 and the second base 111 Position each other.

The separation prevention protrusions 23 extending from the left and right ends on the front wall portion 23 of the inner base 21 are loosely inserted into the separation prevention holes 12c formed in the thin wall portion 12b of the outer base 11 so as to be able to be three-dimensionally mobile. Note that in FIG. 10 and FIG. 11, for the sake of understanding, the inner base 21 and the outer base 11 separated from each other are shown in a state where the separation prevention protrusion 23 a is removed from the separation prevention hole 12 c, but actually, The separation prevention protrusion 23a is not removed from the separation prevention hole 12c, and the inner base 21 and the outer base 11 are not separated.

As shown in FIGS. 7A to 9B, the inner base 21 and the outer base 11 are integrally formed of an insulating material (such as a synthetic resin) by, for example, injection molding in a state where the separation preventing protrusion 23a is inserted into the separation prevention hole 12c. Molded parts. It is to be noted that the inner base 21 and the outer base 11 are formed at any position in the accommodation space 14 (such as the outer surface of the side plate portion 22a) through a tentative connection portion not shown in the figure just after being integrally formed. And the inner surface of the thick-walled portion 12a). In addition, after the first terminal 51 is mounted on the inner base 21 and the outer base 11, the tentative connection portion is cut to achieve the state shown in FIGS. 7A to 9B.

In the first connector 1 in a state shown in FIGS. 7A to 9B, the inner base 21 and the outer base are in a state where the separation preventing protrusion 23 a is loosely inserted into the separation prevention hole 12 c to be movable in the three-dimensional direction. The seat 11 is simply movably connected to each other by the first terminal 51 including the deformed portion 55 and can therefore be elastically moved to each other in a three-dimensional direction. In other words, the dimensional relationship between the separation prevention hole 12c and the separation prevention projection 23a is set such that there is a gap between the inner peripheral surface of the separation prevention hole 12c and the outer peripheral surface of the separation prevention projection 23a and the separation prevention projection 23a prevents separation. The hole 12c is movable in a three-dimensional direction. Therefore, even when the relative positional relationship between the first substrate to which the outer base 11 is fixed and the second substrate to which the second base 111 of the second connector 101 docking to the inner base 21 is changed, all These changes can also be absorbed by the first connector 1.

In addition, the separation prevention hole 12c and the separation prevention protrusion 23a function as a stopper for stopping the relative movement between the inner base 21 and the outer base 11 within a predetermined range. In other words, the size of the gap between the inner peripheral surface of the separation prevention hole 12 c and the outer peripheral surface of the separation prevention protrusion 23 a defines the amount of relative movement between the inner base 21 and the outer base 11. Therefore, the amount of relative movement between the inner base 21 and the outer base 11 is not excessive, and therefore, the amount of deformation of the deformed portion 55 of the first terminal 51 is limited, and therefore, the amount of deformation of the deformed portion 55 does not change. It will be too large, so that the deformation portion 55 is effectively prevented from being damaged.

In particular, when the inner base 21 and the outer base 11 move in the front-rear direction, a rear surface 12g of the separation prevention hole 12c and a rear surface 23g of the separation prevention protrusion 23a function as abutting surfaces that abut each other. The amount of relative movement in the front-rear direction of the inner base 21 and the outer base 11 is limited. In other words, the size of the gap α between the rear surface 12 g of the separation prevention hole 12 c and the rear surface 23 g of the separation prevention protrusion 23 a is limited to the amount of relative movement in the front-rear direction of the inner base 21 and the outer base 11.

It is noted that a front end portion 12e of the thick wall portion 12a and a side end portion 23e of the front wall portion 23 serve as a stop between the inner base 21 and the outer base 11 in a predetermined range and relatively move in the front-rear direction. The role of the second stop. In other words, when the inner base 21 and the outer base 11 approach in the front-rear direction, the front surface 12h of the front end portion 12e and the rear surface 23h of the side end portion 23e function as abutting surfaces that abut each other and are limited The amount of relative movement in the front-rear direction of the inner base 21 and the outer base 11. Note that the size of a gap β between the front surface 12h of the front end portion 12e and the rear surface 23h of the side end portion 23e and the gap between the rear surface 12g of the separation prevention hole 12c and the rear surface 12g of the separation prevention protrusion 23a The size of α is the same.

In addition, the position related to the front-rear direction of the contact portion 54 of the first terminal 51 and the guide rod portion 25 connected to the second terminal 151 (the direction of butt joint between the first connector 1 and the second connector 101) The first nail 81 that fixes the outer base 11 to the first substrate is closer to the second connector 101 side. Therefore, even when the relative positional relationship between the first substrate to which the outer base 11 is fixed and the second substrate to which the second base 111 of the second connector 101 docked with the inner base 21 is changed, The changes can also be absorbed by the first connector 1.

Further, the first nail 81 and the stopper composed of the separation prevention hole 12c and the separation prevention protrusion 23a are located on the same straight line extending in the butting direction between the first connector 1 and the second connector 101, in other words , In a forward and backward direction in a side view. Therefore, for example, when the first connector 1 and the second connector 101 are docked, even if the inner base 21 moves greatly and is stopped by the stopper portion, the rotation torque does not work on the first nail 81. Therefore, the first The nail 81 is not separated from the first substrate.

In the present invention, a state in which a plurality of parts are located on the same straight line refers to a state in which the same straight line passes through at least a part of the plurality of parts, in other words, a plurality of parts at least partially overlap when viewed with a straight line as a line of sight In other words, the state where multiple parts share the same straight line.

In addition, like the first nail 81 and the stopper formed by the separation prevention hole 12c and the separation prevention protrusion 23a, the outer mounting portion 53, the inner mounting portion 56, and the contact portion 54 of the first terminal 51 are also preferably located along a side view. The same straight line extending in the front-to-rear direction.

The configuration of the second connector 101 will be described in detail below.

12A and 12B are a pair of perspective views viewed from above the second connector of this embodiment; FIGS. 13A and 13B are a pair of perspective views viewed from below of the second connector of this embodiment; 14A and 14B are two side views of the second connector in this embodiment.

Note that in FIGS. 12A to 13B, FIGS. 12A and 13A are a pair of views viewed from the front and FIGS. 12B and 13B are a pair of views viewed from the rear; and in FIGS. 14A and 14B. FIG. 14A is a plan view and FIG. 14B is a pair of side views.

In the example shown in FIGS. 1A to 6B, the second connector 101 is shown in the posture where the second substrate is on the upper side, in other words, the posture in which the mounting surface 113 a faces upward, but in FIGS. 12A to 14B, For convenience, it should be noted that the connector is shown in a posture where the second substrate is located on the lower side, in other words, a posture where the mounting surface 113a faces downward. In other words, it should be noted that the second connector 101 shown here is as shown in FIG. 1A to FIG. 6B, and for convenience, it is described in an upside down posture.

As shown in the figure, a pair of left and right guide holes 128 are opened to the abutting surface 113f, and the abutting surface 113f is the front of the front wall portion 113 of the second base 111. When the first connector 1 and the second connector 101 are docked, the guide hole 128 is a hole into which the guide rod portion 25 of the inner base 21 is inserted, and thus the inner base 21 and the second base 111 are positioned with each other.

Therefore, in this embodiment, the first connector 1 includes an outer base 11 including a rear wall portion 13 extending along a width direction, and left and right side wall portions 12 extending forward from both ends of the rear wall portion 13 and by The receiving space 14 defined by the rear wall portion 13 and the two side wall portions 12; the inner base 21 is accommodated in the receiving space 14 and can be moved relative to the outer base 11; the first terminal 51 includes a Outer mounting portion 53, inner mounting portion 56 mounted on inner base 21, tail portion 52 extending from outer mounting portion 53 and connected to a substrate, contact portion 54 extending from inner mounting portion 56 and contacting second terminal 151, and A deformed portion 55 that elastically deforms and connects the outer mounting portion 53 and the inner mounting portion 56; and a stop portion that stops the movement of the inner base 21 relative to the outer base 11 and a first nail 81 mounted on the side wall portion 12, wherein The stopper and the first nail 81 are located on the same straight line extending in a front-rear direction in a side view.

Therefore, the amount of relative movement between the inner base 21 and the outer base 11 is not excessively large, and thus the amount of deformation of the deformed portion 55 is limited, and therefore, the amount of deformation of the deformed portion 55 is not excessively large, thereby effectively preventing deformation. The portion 55 is damaged. In addition, for example, when the first connector 1 and the second connector 101 are docked, even if the inner base 21 moves to the ground and is stopped by the stopper, the rotation torque does not work on the first nail 81.

In addition, the outer mounting portion 53, the inner mounting portion 56, the contact portion 54, the stopper portion, and the first nail 81 are located on the same straight line extending in the front-rear direction in a side view. Therefore, even if the inner base 21 moves on the ground and is stopped by the stopper portion, the rotation moment does not act on the outer mounting portion 53, the inner mounting portion 56, and the contact portion 54.

In addition, a second stopper for stopping the movement of the inner base 21 relative to the outer base 11 in the front-rear direction is also provided, and the stopper, the first nail 81 and the second stopper are located in a side view. In the same straight line extending in the front-to-rear direction. Thereby, the amount of movement of the inner base 21 and the outer base 11 in the front-rear direction is reliably limited, and therefore, damage to the deformed portion 55 is more effectively prevented. Note that the stopper portion is formed of a separation prevention hole 12c formed in the side wall portion 12 and a separation prevention protrusion 23a of the insertion separation prevention hole 12c protruding outward from the inner base 21 in the width direction, and the inner base 21 The amount of relative movement with the outer base 11 is limited by the size of a gap between the inner peripheral surface of the separation prevention hole 12c and the outer peripheral surface of the separation prevention protrusion 23a.

In addition, the deformed portion 55 includes: a connecting portion 55b bent so that the front end faces forward; a first U-shaped turning portion 55c having a base end connected to the front end of the connecting portion 55b; and a ground bend and U-turn to make the front end face rearward A middle portion in the direction; a second U-shaped turning portion 55e having a base portion 55f connected to the lower end or the upper end of the inner mounting portion 56 and a middle portion bent and U-turned so that the front end faces the forward direction And a crank portion 55d connecting the front end of the first U-turn portion 55c and the front end of the second U-turn portion 55e. Therefore, the deformed portion 55 has a portion that is long enough and can be elastically deformed, and thus can be elastically and flexibly deformed in a three-dimensional direction.

In addition, the outer mounting portion 53, the inner mounting portion 56, the tail portion 52, and the deformed portion 55 are formed of a single metal plate, and the contact portion 54 includes a thick plate portion 54c formed by folding the metal plate into two layers. It is noted that the second terminal 151 includes a contact protrusion 154c that holds the thick plate portion 54c from both sides; and an arm portion 154a that can be elastically deformed and presses the front end of the contact protrusion 154c against the thick plate portion 54c. Therefore, the contact state between the contact protrusion 154c and the thick plate portion 54c is reliable. In addition, the thick plate portion 54c is thick, and therefore, durability is high, and the contact state between the contact protrusion 154c and the thick plate portion 54c is not defective.
