[0028]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 3 show an embodiment of a connection structure for power supply of an automobile door according to the present invention.

As shown in FIG. 1, the power supply connection structure of the vehicle door is a switch structure for supplying power to the vehicle body to various accessories and the like in the door, and includes a vehicle body side connector 11 and a door side connector. 40.

For convenience of description, the front-rear direction, left-right direction, and up-down direction are defined as follows. The front-back direction is defined as the direction in which the connectors 11 and 40 are fitted, and the side facing the mating connectors 11 and 40 is the front side of each connector. The left-right direction (horizontal direction) of the connectors 11 and 40 is defined as the direction in which the pair of female terminals 25 opens and closes. Since both connectors 11 and 40 are symmetrical left and right, there is no need to distinguish between left and right. The vertical direction is defined as the direction in which the female terminal 25 is inserted into the cylindrical shaft 34, and the side on which the female terminal 25 is mounted on the bottom wall 14b of the case 14 is the lower side.

The vehicle body side connector 11 comprises a box-shaped housing 12 having an internal space 13 and a female terminal 25 accommodated in the housing 12. The housing 12 includes a case 14 on which the female terminal 25 is placed, and a cover 17 covered by the case 14.

The housing 12 has a flange (not shown), and is fixed to the vehicle body using the flange. Further, a connector (not shown) for connecting a power line is provided integrally with the vehicle body side connector 11. Cover 1
7 has an opening 18 for inserting a male terminal 46 therein.
, And each female terminal 25 is accommodated inside each opening 18. Each opening 18 is closed by a shutter 33 described later.

The female terminal 25 comprises a pair of contact members 26 which can be opened and closed in the left-right direction, and is arranged to face the tab-shaped electric contact portion 47 of the male terminal 46. Each contact member 26
Is formed by cutting out a thin flat plate material and bending it into an S-shape or an inverted S-shape as shown in FIG. Each contact member 26 is swingably supported by a cylindrical shaft 34, and is urged in a vertical direction and a horizontal direction by a torsion coil spring (elastic member) 38 that is externally inserted into the cylindrical shaft 34.

Each contact member 26 is connected to both connectors 11, 40.
The spring receiving portion 27 urged by the torsion coil spring 38, the inclined plate portion 31 extending forward following the spring receiving portion 27, and the The contact portion 32 is formed.

The electric contact portion 32 is located at the back of the shutter 33 following the front of the inclined plate portion 31. The pair of electric contact portions 32 are urged by a torsion coil spring 38 so as to be able to contact the male terminal 46 with an appropriate contact pressure.
A waterproof shutter 33 is provided at the tip of the electric contact portion 32.

In order to obtain reliable contact between the male terminal 46 and the female terminal 25, a pair of shutters 33 are used to release the female terminal 2 when the vehicle body side connector 11 and the door side connector 40 are detached.
The electric contact portion 32 is urged inward and closely adhered in order to close the gaps 5 and to prevent the entry of impurities such as water droplets and dust.
If the urging force (contact pressure) is too strong, the male terminal 46 is inserted (entered) and may be bent by buckling or the like, so that the contact pressure in the closing direction of the pair of electric contact portions 32 is appropriate. The strength of the leg 38b of the torsion coil spring 38 is determined so as to be large.

The shutter 33 is attached to the tip of the electric contact portion 32 and can be opened and closed integrally with the electric contact portion 32. Various attachment means can be used to attach the shutter 33. In the present embodiment, the attachment is performed by engaging the hole 33c of the shutter 33 with the locking projection 32a of the electric contact portion 32.

Such a shutter 33 has a guide surface 33a inclined inwardly in a tapered shape, and a closing surface 33b closely contacting the inner end of the guide surface 33a. Closure surface 3
Due to the close contact between 3b, intrusion of water droplets and dust into the female terminal 25 is prevented. The guide surface 33a is a guide surface of the male terminal 46, so that even if there is a misalignment or an angular deviation between the male terminal 46 and the female terminal 25, the deviation is absorbed and the terminal is reliably inserted. The connection between them can be made.

When the male terminal 46 and the female terminal 25 are in contact with each other, the closing surface 33b of the shutter 33 is not in contact with the electrical contact portion 47 of the male terminal 46, so that the male terminal 46 can be inserted. The accompanying sliding is avoided, and friction and wear are prevented. In the contact state of the two terminals 25 and 46, the shutter 33 opened and closed right and left is also prevented from interfering with the wall of the cover 17.

Since the shutter 33 is formed larger than the opening 18 of the housing 12, the opening 18 can be reliably closed. Since a gap is formed between the tip of the shutter 33 and the housing 12,
The friction of the shutter 33 is prevented, and the opening and closing of the shutter 33 can be performed smoothly.

The inclined plate portion 31 is provided with a spring receiving portion 27 described later.
And a member connecting the electrical contact portion 32, and is inclined inward toward the front. As shown in FIG.
At the lower end of 1, a locking step 31 a is formed to engage with a concave portion provided on the bottom wall 14 b of the case 14 (see FIG. 1). The locking step 31a is provided with the female terminal 25 and the male terminal 4
This is for restricting the backward movement of the female terminal 25 when 6 is inserted.

As shown in FIG. 3, the torsion coil spring 38
The spring receiving portion 27 urged toward the bottom plate portion 27a is bent rightward inward following the side plate portion 27a and the lower end of the side plate portion 27a.
b and continues to the rear of the inclined plate portion 31.
The spring receiving portion 27 has an L-shape or an inverted L-shape in cross section, and a swelling electrode contact portion 29 is formed on the outer surface of the side plate portion 27a.

An insulating material 30 is attached to the inner and outer surfaces of the side plate portion 27a excluding the electrode contact portion 29 and the bottom plate portion 27b. As the insulating material 30, a synthetic resin material is preferable from the viewpoint of insulating properties and adhesion to the substrate. Since the synthetic resin material is integrally attached by insert molding, the adhesion to the substrate is extremely good.

The reason why the insulating synthetic resin material is applied in this way is to make each pair of contact members 26 function as an individual electrode connecting the circuit on the vehicle body side and the circuit on the door side. That is, the reason why the synthetic resin material is attached to the side plate portion 27a is that when the male terminal 46 is inserted into the female terminal 25 and the spring receiving portion 27 approaches inward, the rear ends of the side plate portions 27a Are likely to come into contact with each other. Also, the bottom plate 27
The reason why the synthetic resin material is also applied to b is to prevent electrical contact of the bottom plate 27b which is superimposed on top and bottom.

The bottom plate 27b has a shape combining a rectangle and a semicircle. A shaft hole 28 is formed in the center of the bottom plate 27b. A cylindrical shaft 34 is inserted into the shaft hole 28, and each of the contact members 26 can swing right and left around the cylindrical shaft 34 as a rotation center.

The cylindrical shaft 34 corresponds to a support shaft of each contact member 26 that swings in the left-right direction, and one end (lower side) of the cylindrical shaft 34 is connected to a boss of the terminal housing 37 of the case 14. The other (upper) end of the cylindrical shaft 34 is fitted to the boss of the cover 17 (not shown). Both bosses are cylindrical shaft 3
4, the positioning of the case 14 and the cover 17 is performed.

The torsion coil spring 38 is stepped on the bottom plate 27b so that its axial direction (extending and contracting direction) is aligned with the vertical direction. The torsion coil spring 38 is fixed by combining the case 14 and the cover 17 up and down. That is, the boss 19 of the case 14 and the boss of the cover 17 are opposed to each other, and are fixed by fastening bolts (not shown).

The coil winding portion 38a of the torsion coil spring 38
Each contact member 26 is attached without rattling since the bottom plate 27b is pressed downward, but the elastic force (pressing force) of each contact member 26 swings in the horizontal direction. The elastic force is set to such an extent that the operation can be performed smoothly. That is, the torsion coil spring 38
The effective number of turns of the coil, the average diameter of the coil, the diameter of the wire, and the like are determined so that a predetermined elastic force can be obtained.

A pair of legs 38b of the torsion coil spring 38
Urges the side plate portion 27a of the spring receiving portion 27 outward in the left-right direction and urges the electric contact portion 32 inward in the left-right direction. The swelled electrode contact portion 29 provided on the outer surface of the side plate portion 27a comes into contact with and is electrically connected to the electrode portion 36 embedded in the partition wall 35. By forming the electrode contact portion 29 in a smooth bulging spherical shape, even if each contact member 26 swings in the horizontal direction, the contact between the electrode contact portion 29 and the electrode portion 36 is always maintained. In addition, the reliability of the electrical connection is maintained. Note that the electrode contact portion 29 may have a U-shape or a convex shape.

The electrode portion 36 includes a partition wall 35 and a partition wall 35.
And is buried in the left and right side walls 14 a of the case 14, which also serves as the electrode contact portion 29 of each contact member 26. A conductive metal material such as a copper plate, a conductive synthetic resin, or the like is applied to the electrode portion 36, and is incorporated by integral molding or press fitting. The electrode portion 36 is connected to a tab terminal (not shown) of a female connector for power connection provided at a lower portion of the housing 12 and is connected to a circuit on the vehicle body side.

As shown in FIGS. 1 and 2, the door-side connector 40 is housed in a box-shaped housing 41 having an opening space 42 at the front end and in the internal space of the housing 41, and is provided between the female terminal 25. And a male terminal 46 to be inserted. The housing 41 includes a case 43 facing the vehicle body-side connector 11 and a cover 44 located behind the case 43 and inserted inside the case 43. The cover 44 and the case 43 are configured as separate bodies, but this is for molding reasons and may be configured integrally. The cover 44 and the case 43 are made of insulating synthetic resin.

The male terminals 46 are arranged in parallel at equal pitch intervals. The base end of the male terminal 46 is

Is located in the opening space 42 of the housing 41. In this position, the male terminal 46 is
Since it is not exposed to the outside, interference with the outside is prevented.

A tab-shaped electric contact portion 47 is formed at one end of the male terminal 46, and a spring mounting portion 49 is formed at the other end. The spring mounting portion 49 is opposed to a spring receiving protrusion 45 projecting from the rear wall 44 a of the cover 44, and a coil spring 50 is elastically provided between the spring mounting portion 49 and the spring receiving protrusion 45.

The electrical contact portion 47 is composed of conductor portions 47a on both sides in the width direction (horizontal direction) and a straight insulating member 48 located between the conductor portions 47a on both sides. Insulation member 4
Reference numeral 8 is made of a synthetic resin material such as plastic, and is formed integrally with the conductor portion 47a by, for example, integral molding (insert molding or the like). The insulating member 48 and the conductor 47a are tightly adhered to each other so that the joint between the insulating member 48 and the conductor 47a is not damaged even when the terminals 25 and 46 are repeatedly contacted and separated.

The conductors 47a are provided on both sides of the insulating member 48, and the ends of the conductors 47a are covered with the insulating member 48. Therefore, the conductors 47a on both sides are independent of each other without contacting each other. It functions as an electrode.

As the coil spring 50, a cylindrical coil spring 50 compressible in the axial direction is used. The male terminal 46 is strongly urged in the insertion direction, but can be retracted if carelessly interferes with the outside. The strength of the coil spring 50 is set to be greater than the insertion force of the male terminal 46 into the female terminal 25, so that the male terminal 46 can be smoothly inserted between the female terminals 25. ing.

In the opening space 42 of the housing 41, a cushion (not shown) for absorbing impact such as urethane rubber for the vehicle body side connector 11 is provided.
