Abstract

PURPOSE:To absorb a disorder of the alignment of a male terminal multipolar metal fitting while carrying out the posture maintaining and the removal prevention of the male terminal metal fitting. CONSTITUTION:A male terminal metal fitting 3 is maintained in a specific posture by a rubber elastic holder 4 in the condition to block the removal from a playable hole 23 by locking an elastic removal preventive piece 34 to a locking member 26, but it can be displaced against the elastic force of the elastic holder 4. When the alignment of the connecting end of the male terminal metal fitting 3 with a printed circuit board or a female terminal metal fitting is out of order, the disorder of the alignment can be absorbed by displacing the male terminal metal fitting 3 in the playable hole 23 against the elastic force of the elastic holder 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board connector capable of absorbing misalignment of terminal fittings.

[0002]

2. Description of the Related Art A board connector has a male terminal fitting which is inserted into a housing having a hood so that a connecting end portion of the male terminal fitting to the female terminal fitting is projected into the hood and the male terminal fitting is also provided. Connect the connection end of the
It has a configuration in which it is bent in a letter shape and protrudes to the side opposite to the hood portion. In such a board connector, in order to improve workability when fitting the male terminal fitting and the female terminal fitting,
It is necessary to keep the male terminal fitting in a predetermined fitting posture with respect to the female terminal fitting in the hood portion. Further, in order to improve workability when fitting the male terminal fitting into the insertion hole of the printed board, it is necessary to keep the male terminal fitting in a predetermined posture with respect to the connection position with the printed board. Furthermore, the male terminal fitting is attached to the connector by inserting the male terminal fitting from the hood side or the opposite side. When a large force in the opposite direction to the male terminal fitting is applied to the male terminal fitting, the male terminal fitting may come off, so it is necessary to prevent the male terminal fitting from coming off.

As a printed circuit board connector in which the alignment is ensured and the retaining is performed as described above, there are those shown in FIGS. 13 and 14. This is because the male terminal fitting 3 in a straight state is press-fitted into the through hole 2 formed in the housing 1 from the hood portion 4 side, and the stopper 5 on the inner wall of the through hole 2 is provided with locking projections on both side edges of the male terminal fitting 3. The male terminal fitting 3 is pushed until it reaches a predetermined mounting position at which the male terminal 6 comes into contact, and then the portion of the male terminal fitting 3 projecting to the side opposite to the hood portion 4 is bent downward in an L-shape. This is a configuration in which the metal fitting 3 is attached. In the state where the male terminal fitting 3 is attached to the housing 1 in this way, the male terminal fitting 3 is press-fitted into the through hole 2, so that the through hole 2
A large pressing force acts on the surface of the male terminal fitting 3 from the inner wall surface of the. Due to this pressing force, the male terminal fitting 3
The male terminal fitting 3 is held in a fixed posture without rattling in any of the up, down, left, and right directions, and the frictional resistance generated by pressing prevents movement of the male terminal fitting 3 in the pulling direction.

[0004]

However, with the method of mounting the male terminal fitting 3 in the housing 1 by press fitting as described above, the posture of the male terminal fitting 3 after mounting cannot be adjusted. Therefore, when the projecting end of the male terminal fitting 3 into the hood 4 is misaligned with the female terminal fitting (not shown), the male terminal fitting 3
When the male terminal fitting 3 and the female terminal fitting are fitted together, the male terminal fitting 3 is fitted into the female terminal fitting in an inclined posture, and as a result, the frictional resistance force generated between the two terminal fittings at the time of fitting becomes excessive. As a result, the workability of the fitting operation may be deteriorated. Similarly, the end portion of the male terminal fitting 3 that protrudes downward on the side opposite to the hood portion 4 is a printed circuit board (not shown).
When the male terminal metal fitting 3 is fitted into the insertion hole while fixing the housing 1 to the printed circuit board, the male terminal metal fitting 3 is aligned with the insertion hole when the alignment error occurs in the insertion hole. As a result, the male terminal fitting 3 is forcibly inserted into the insertion hole while being bent, which not only reduces workability but also makes it impossible to mount the male terminal fitting 3 on the printed circuit board if the alignment is greatly misaligned. There is a fear.

In order to solve such a problem, the male terminal fitting 3 is mounted in the through hole 2 with a gap so that it can be displaced with respect to the housing 1, and when it is fitted with the female terminal fitting. It is also possible to absorb the misalignment of the alignment at the time of attachment to the printed circuit board. But,
If a gap is provided between the male terminal fitting 3 and the through hole 2, the holding force of the male terminal fitting 3 is greatly reduced.
The function of holding the male terminal fitting 3 in a predetermined posture with respect to the female terminal fitting and the printed circuit board and the function of retaining the male terminal fitting 3 from the through hole 2 are lost.

The present invention has been made in view of the above circumstances, and the alignment of the male terminal fitting can be performed without losing the function of holding the male terminal fitting in a predetermined posture and the function of retaining the male terminal fitting. The purpose is to absorb madness.

[0007]

As means for solving the above-mentioned problems, the invention of claim 1 is characterized in that a male terminal fitting is penetrated and mounted in a housing having a hood part, and a female terminal fitting of the male terminal fitting is provided. In the board connector in which the connection end of the connector protrudes into the hood and the connection end of the male terminal fitting with the board projects toward the opposite side of the hood, the male terminal fitting is inserted into the housing and inserted. A loose fitting hole that allows free movement in a direction intersecting the direction is formed, and a retaining means that prevents the male terminal fitting from slipping out in the direction opposite to the insertion direction, and the male terminal fitting is elastically fixed in the loose fitting hole. The elastic holding means for holding the posture is provided.

According to a second aspect of the present invention, in the first aspect of the present invention, the elastic retaining piece formed by cutting and raising the male terminal fitting is provided in the engaging portion formed in the loose fitting hole in the direction opposite to the hood portion. The retaining means is configured by locking in the retaining state.

The invention of claim 3 relates to claim 1 or claim 2.
In the invention described above, the elastic holding means is configured such that an elastic holding piece formed by cutting and raising the male terminal fitting is brought into contact with the inner wall of the loose fitting hole.

[0010]

According to the first aspect of the invention, when the male terminal fitting is inserted into the loose fitting hole, the male terminal fitting is held in a fixed posture by the elastic force of the elastic holding means. It is also possible to displace it in a direction intersecting the insertion direction. In this way, the male terminal fitting can be displaced in the loose fitting hole, but the male terminal fitting is prevented from coming off the loose fitting hole by the retaining means. If the alignment of the connection end of the male terminal fitting with the board or the alignment of the connection end with the female terminal fitting is not correct, the male terminal fitting should not resist the elasticity of the elastic holding means in the loose fitting hole. By displacing, the misalignment of the connection end is absorbed and adjusted.

According to the second aspect of the invention, the male terminal fitting can be mounted by inserting the male terminal fitting into the loose fitting hole from the side opposite to the inside of the hood portion. At this time, the elastic retaining piece enters into the loose fitting hole while elastically deforming, and when it reaches the predetermined mounting position, elastically returns to engage with the locking portion, and thus the male terminal fitting is held in the retaining state. To be done.

According to the third aspect of the present invention, the male terminal fitting mounted in the loose fitting hole is brought into a fixed posture by the reaction force generated by the elastic holding piece pressing the inner wall of the loose fitting hole by the elastic restoring force of the elastic holding piece. Retained. When adjusting the alignment of the male terminal fitting, the elastic holding piece is elastically deformed to displace the male terminal fitting in the loose fitting hole.

[0013]

As described above, according to the invention of claim 1, the elastic holding means for holding the male terminal fitting in a fixed posture by the elastic force in the loose fitting hole, and the inserting direction of the male terminal fitting. Since the retaining means for preventing the male terminal fittings from coming out in the opposite direction is provided, the misalignment of the male terminal fittings can be prevented without losing the function of holding the male terminal fittings in a predetermined posture and the function of retaining the male terminal fittings. It has the effect of being absorbed. According to the invention of claim 2, in addition to the above effects,
Since the male terminal fitting can be inserted into the loose fitting hole from the side opposite to the inside of the hood, it is easier to insert the male terminal fitting than when inserting the male terminal fitting from the inside of the hood. There is an effect that can be. Also, since the male terminal fitting can be inserted into the loose fitting hole while being bent in an L-shape, the bending work is completed together with the forming work in the molding step of the male terminal fitting performed prior to the inserting step. By doing so, it is possible to improve the working efficiency as compared with the case where the bending step is performed after the insertion. According to the invention of claim 3, in addition to the above effect, since the elastic holding means is composed of an elastic holding piece formed on the male terminal fitting itself, the elastic holding means is formed by a component separate from the male terminal fitting. Compared with, there is an effect that the cost can be reduced by reducing the number of parts. Further, when the male terminal fitting is inserted into the loose fitting hole, there is no fear that the separate component for elastic holding is displaced from the predetermined mounting position, so that the workability of inserting the male terminal fitting is excellent.

【Example】

<Example 1> Hereinafter, Example 1 embodying the present invention will be described with reference to FIG.
It will be described with reference to FIGS. The board connector of this embodiment includes a housing 2, a male terminal fitting 3, and an elastic holder (corresponding to elastic holding means which is a constituent of the present invention) 4. The housing 2 is made of a non-conductive synthetic resin material, and is positioned and fixed at a predetermined position on the upper surface of a printed circuit board (not shown). The housing 2 is a substantially rectangular plate-shaped housing main body portion 21 that stands upright at a right angle to the upper surface of the printed circuit board.
And a hood portion 22 that protrudes forward from the outer peripheral edge of the front surface of the housing body portion in a tubular shape. The housing body portion 21 is formed with a plurality of loose fitting holes 23 that are open at the rear end surface of the hood portion 22 and the rear surface of the housing body portion 21 and are arranged at predetermined positions. From the rear side (the side opposite to the inside of the hood portion 22) of the male terminal fitting 3
Is to be inserted. The left and right inner wall surfaces of the loose fitting hole 23 are flat surfaces parallel to each other from the opening at the rear end to the front end portion, and the front end portion (end portion on the hood portion 22 side) has left and right inner surfaces as shown in FIG. A pair of stoppers 24, 24 is formed by projecting both inner walls inward. Further, as shown in FIG. 3, the upper and lower inner wall surfaces of the loose fitting hole 23 are flat surfaces parallel to each other from the opening at the rear end thereof to the substantially middle position in the length direction, and the substantially middle position in the length direction. The space from the rear end to the rear end is a fitting portion 25 into which the elastic holding body 4 is fitted. On the front side of the fitting portion 25, the inner wall surface on the lower side is stepped and higher than the fitting portion 25, and the inner wall surface on the upper side expands in a stepped manner and the locking portion (of the present invention). (Which constitutes a retaining means) 26, and the elastic retaining piece 34 of the male terminal fitting 3 is engaged with the engaging portion 26.

The male terminal fitting 3 has a shape that is elongated and bent into an L-shape as a whole, and has a front extending portion 31 and a downward extending portion 3.
Consists of two. In the male terminal fitting 3, the front extending portion 31 is penetrated into the loose fitting hole 23 with a space therebetween so that the hood portion 2
2 and project the lower extension 32 into the housing 2
The front end of the front extending portion 31 is fitted to the female terminal fitting (not shown) of the female connector inserted in the hood portion 22 while being attached to the rear of the lower extending portion 32. Is to be inserted into an insertion hole (not shown) of the printed circuit board. At the base end position of the front extension portion 31 of the male terminal fitting 3 (a position near the lower extension portion 32), a pair of rectangular locking protrusions 33, 33 extending outward from both left and right edges thereof.
Are formed. Further, at a position between the two locking projections 33, 33 of the front extension 31, an elastic retaining piece protruding obliquely rearward on the upper surface side by constituting a cut-up portion thereof (constituting the retaining means of the present invention. ) 34 are integrally formed. The elastic retaining piece 34 is capable of elastic bending downward and elastic return upward.

The elastic holding member 4 constitutes the elastic holding means of the present invention, and is made of rubber in the shape of a rectangular tube having a fixed length. The front extension 31 of the male terminal fitting 3 is tightly fitted in the elastic holder 4, and the elastic holder 4 is tightly fitted in the fitting portion of the loose fitting hole 23. It has become. Such an elastic holder 4 is capable of maintaining a constant attitude of the male terminal fitting 3 by causing a slight elastic deflection in a state where the male terminal fitting 3 is fitted into the loose fitting hole 23. The male terminal fitting 3 is provided with elasticity so that elastic bending can occur when an external force is applied to the male terminal fitting 3.

Next, the operation of this embodiment will be described. When attaching the male terminal fitting 3 to the housing 2, first, the elastic holding body 4 is fitted from the tip end side of the downward extension portion 32 and moved to the front extension portion 31 side, so that the locking projection 33 is removed. Also attach it at a certain position a little behind. The male terminal fitting 3 to which the elastic holder 4 is attached is inserted into the loose fitting hole 23 from the rear side of the housing 2 with the extending end of the front extending portion 31 facing forward. In the middle of the insertion, the elastic retaining piece 34 comes into contact with the upper surface wall of the loose fitting hole 23 to cause downward elastic bending, and the elastic holding body 4 is fitted into the loose fitting hole 23 so that Insertion resistance increases due to the close contact, but continue to insert by pushing in as it is.

When the male terminal fitting 3 reaches the predetermined mounting position, the locking projection 33 contacts the stopper 24, and the male terminal fitting 3 cannot be inserted any further. At the same time, the elastic retainer piece 34 aligns with the locking portion 26 and locks with the rear step portion 26a. In this state, the locking protrusion 33
The male terminal metal fitting 3 is prevented from moving forward by being locked to the stopper 24, and the locking portion 2 of the elastic retaining piece 34 is locked.
The male terminal fitting 3 is locked at 6 to prevent the male terminal fitting 3 from moving backward, so that the male terminal fitting 3 is positioned at a predetermined mounting position.

In this state, the elastic holder 4 is slightly elastically bent, the outer surface of the elastic holder 4 is in close contact with the entire inner wall surface of the loose fitting hole 23, and the inner surface is male. The terminal fitting 3 is in close contact with the entire upper, lower, left, and right sides, and the close contact state extends over a range of a certain length in the front-rear direction. Due to the elastic return force of the elastic holder 4, the male terminal fitting 3 is normally held in a fixed posture in the loose fitting hole 23 in a state in which the free movement in any of the up, down, left and right directions is restricted. In this state, the front extending portion 31 projecting into the hood portion 22 is aligned so as to be smoothly fitted to the female terminal fitting, and extends downward from the rear of the housing 2. The alignment of the part 32 is ensured so that the part 32 can be smoothly fitted into the insertion hole of the printed circuit board.

Further, the male terminal fitting 3 in the loose fitting hole 23
As shown in FIGS. 2 and 4, a space is provided between the elastic holder 4 and the inner wall of the loose fitting hole 23, and the elastic holder 4 holding the male terminal fitting 3 is elastically bendable. As a result, when an external force acts on the male terminal fitting 3 in the loose fitting hole 23 in a direction intersecting the insertion direction, the male terminal fitting 3 may be displaced in the same direction as the external force while the elastic holding body 4 is elastically bent. It is possible. Therefore, when the tip of the downward extending portion 32 is misaligned with the insertion hole of the printed board when the connector of the present embodiment is mounted on the printed board, the downward extending portion 32 is By displacing in the front-rear direction and the left-right direction, the misalignment can be absorbed, and the downward extending portion 32 can be aligned with the insertion hole. At this time,
While the elastic holding body 4 elastically bends in the loose fitting hole 23, the male terminal fitting 3 is pivotally displaced about the portion held by the elastic holding body 4.

After mounting the housing 2 and the downward extending portion 32 on the printed circuit board, the female terminal fitting of the female connector fitted in the hood portion 22 and the male terminal fitting 3 are fitted. At this time, if the front extension 31 is misaligned with the female terminal fitting, the front extension 31 will be
With the fitting with the female terminal fitting, the elastic holding body 4 is elastically flexed and displaced so as to swing in any of the up, down, left and right directions. When the male terminal fitting 3 is fitted into the female terminal fitting while adjusting the alignment in this way, the male terminal fitting 3 and the elastic holder 4 are elastically deformed. However, since the elastic holding body 4 is made of rubber, its elastic force is relatively small, and therefore the bending of the male terminal fitting 3 is the entire length from the tip of the downward extending portion 32 to the tip of the forward extending portion 31. Will occur over. In the conventional connector, the male terminal metal fitting is fixed at the housing penetrating portion, and the elastic bending of the male terminal metal fitting due to the alignment adjustment occurs only in the front extension portion. Since the elastic bending of the metal fitting 3 occurs over its entire length, the resistance to the bending deformation of the male terminal fitting 3 is small, and the fitting work between the male terminal fitting 3 and the female terminal fitting can be easily performed.

Further, in this embodiment, the male terminal fitting 3 can be inserted into the loose fitting hole 23 from the rear surface side of the housing 2 opposite to the inside of the hood portion 22. Therefore, as compared with the case where the male terminal fitting 3 is inserted from the hood portion 22 side, the male terminal fitting 3 can be inserted more easily. Also, the male terminal fitting 3 is the housing 2
Since it is designed to be inserted from the rear surface side, it is possible to finish the process of bending the male terminal fitting 3 into an L-shape together with the forming work in the forming process of the male terminal fitting 3 prior to the insertion. As a result, it is possible to improve the work efficiency as compared with the case where the straight male terminal fitting is inserted and then bent into an L shape.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIGS. The board connector of the present embodiment includes a housing 6 and elastic holding means 7.
It is composed of a male terminal fitting 7 provided with 5. The housing 6 includes a housing body 61 and a hood 62. Inside the loose fitting hole 63 formed in the housing body 61, a pair of left and right stoppers 64, 64 projecting inward from a front end portion (end portion on the hood portion 62 side) and an upper wall are opened. A stop 65 is formed. Further, a pair of upper and lower tapered surfaces 66a and 66b are formed on the opening edge on the rear end side of the loose fitting hole 63 by notching the upper edge and the lower edge of the loose fitting hole 63 so as to be inclined outward.

The male terminal fitting 7 is L-shaped and comprises a front extending portion 71 and a lower extending portion 72.
Similarly to the male terminal fitting 3 of the first embodiment, a pair of left and right locking projections 73, 73 and an elastic retaining piece 74 are formed on the. The elastic holding means 75 is integrally provided on the male terminal fitting 7 of this embodiment. At the rear position of the locking projection 73, a pair of horizontal holding pieces 76, 76 extending diagonally from the left and right side surfaces of the front extending portion 71 toward the rear outer side are integrally formed. The horizontal holding piece 76 has a plate-like shape, and is capable of elastic bending in a direction in which a plate surface oriented in the up-down direction is brought into contact with and separated from the side surface of the front extending portion 71. Further, at a position rearward of the horizontal holding piece 76, the left and right side surfaces of the front extending portion 71 are separated into a plate shape and one of them (see FIG. 8).
A pair of upper and lower holding pieces 77 by projecting the plate-shaped part of the lower one) obliquely backward and downward and projecting the plate-shaped part of the other (the upper one in FIG. 8) obliquely rearward and upward.
a and 77b are formed in a pair. These upper and lower holding pieces 77a and 77b are capable of elastic bending in the vertical direction in a state where the plate surface is oriented parallel to the side surface of the front extending portion 71 and the projecting end is projected from both the upper and lower surfaces of the front extending portion 71. Has become. The horizontal holding pieces 76, 76 and the upper and lower holding pieces 77a, 77b constitute an elastic holding means 75.

Next, the operation of this embodiment will be described.
The male terminal fitting 7 is attached to the housing 6 by attaching the male terminal fitting 7 from the rear side of the housing 6 with the front extending portion 71 facing forward.
Do by inserting inside. During insertion, the elastic retaining piece 74 abuts the upper surface wall of the loose fitting hole 63 to cause downward elastic bending, and the horizontal holding pieces 76, 76 abut both left and right side walls of the loose fitting hole 63. As a result, the insertion resistance increases due to the elastic bending toward the inside, but the insertion is continued by pushing in as it is. Then, when the male terminal fitting 7 reaches a predetermined mounting position, the locking projection 73 contacts the stopper 64 and further insertion becomes impossible, and at the same time, the elastic stopper piece 74 aligns with the locking portion 65. Lock it on the rear step. The forward movement of the male terminal fitting 7 is prevented by the engagement of the engaging projection 73 with the stopper 64, and the backward movement of the male terminal fitting 7 is achieved by the engagement of the elastic retaining piece 74 with the engaging portion 65. Is blocked,
Accordingly, the male terminal fitting 7 is positioned at a predetermined mounting position. In this state, the horizontal holding pieces 76, 76 are in contact with the side wall of the loose fitting hole 63 while causing a slight elastic bending, and the upper and lower holding pieces 77a, 77b generate a slight elastic bending while causing the loose fitting hole 63. The rear end tapered surfaces 66a and 66b are in contact with each other. Due to the elastic restoring force of the holding pieces 76, 76, 77a, 77b, the male terminal fitting 7 is normally set in the loose fitting hole 63.
It is held in a fixed posture in a state in which the free movement in any of the up, down, left and right directions is restricted. In this state, the front extending portion 71 is aligned so that the female terminal fitting (not shown) can be smoothly fitted, and the lower extending portion 72 has a printed circuit board (not shown). ) Alignment is ensured so that a smooth insertion can be performed with respect to the insertion hole of FIG.

Further, since the horizontal holding pieces 76, 76 and the upper and lower holding pieces 77a, 77b are elastically bendable, when an external force acts on the male terminal fitting 7 in the loose fitting hole 63 in a direction intersecting the insertion direction. The male terminal fitting 7 can be displaced while the horizontal holding pieces 76, 76 or the upper and lower holding pieces 77a, 77b are elastically bent. Therefore, when the tip of the downward extending portion 72 is misaligned with respect to the insertion hole of the printed circuit board, the downward extending portion is displaced to the front, rear, left, and right to absorb the misalignment and move downward. The extension 72 can be aligned with the insertion hole. At this time, in the loose fitting hole 63, the horizontal holding pieces 76, 76 or the upper and lower holding pieces 77a, 77b are elastically bent while the male terminal fitting 7 is held by the elastic holding body 4. Pivot displacement as the center.

Further, when the front extending portion 71 is misaligned with the female terminal fitting in a state where the front extending portion 71 is mounted on the printed circuit board, the front extending portion 71 may not fit into the female terminal fitting. Along with this, the posture is corrected while being displaced so as to swing in one of the front, rear, left, and right directions, and the alignment error is absorbed. When the male terminal fitting 7 is fitted to the female terminal fitting while adjusting the alignment in this way, when the male terminal fitting 7 and the horizontal holding piece 76,
76 or the upper and lower holding pieces 77a, 77b are elastically deformed, but the holding pieces 76, 77a, 77b are elastically deformable, so that the male terminal fitting 7 is bent from the tip of the downward extending portion 72 thereof. It will occur over the entire length of the front extension 71. Therefore, as compared with the conventional connector in which the male terminal fitting is fixed at the housing penetrating portion and the elastic bending of the male terminal fitting due to the alignment adjustment occurs only in the front extension portion, the male terminal fitting of the present embodiment. The resistance against the bending deformation of 7 is small, and the fitting work between the male terminal fitting 7 and the female terminal fitting can be easily performed.

In this embodiment, the horizontal holding pieces 76, 76 and the upper and lower holding pieces 77a, 77b constituting the elastic holding means 75.
Since it is integrally formed with the male terminal fitting 7, compared with the case where the elastic holding piece is provided separately from the male terminal fitting 7, it is possible to reduce the cost by reducing the number of parts. . Further, when the male terminal fitting 7 is inserted into the loose fitting hole 63, there is no concern that the separate elastic holding component will be displaced from the predetermined position attached to the male terminal fitting 7, so the male terminal fitting 7
Excellent workability for inserting.
