DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The connector of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a basic configuration of a connector according to an embodiment of the present invention.
FIG. 1A is a partial side sectional view, FIG. 2B is a partial front sectional view, and FIG. 1C is a partial front sectional view showing a fitting connection state.

This connector comprises a pin-side connector 1 and a socket-side connector 2 which are fitted together.
The pin side connector 1 is an insulator 1 having an open upper surface.
A plurality of pin contacts 11 are erected and held on the bottom wall of the insulator 10. The pin contact 11 is formed of a flexible conductive metal material, and has a thin and long plate shape as a whole.

The socket-side connector 2 has an insulator 20 as a base, and a plurality of socket contacts 21 are fixedly held on the insulator 20. Each socket contact 21 has a socket portion H opened toward the connection side with the pin-side connector 1.

The inner surface of the socket portion H is undulated to hold the pin contact 11 in a flexible manner. The socket portion H is orthogonal to the axial direction of the pin contact 11 by different convex portions 21a and 21b separated from each other. Can be provided with contact forces in opposite directions to each other. In addition, the convex portion 21b formed on the far side of the socket portion H is formed by removing the convex portion 21b formed on the far side of the socket portion H in advance by being cut out in a concave shape. Have been.

In this connector, the axis d of the pin contact 11 in the pin-side connector 1 is larger than the distance d between the tip of the projection 21a in the socket H of the socket-side connector 2 and the tip of the projection 21b opposed thereto. The width dimension in the direction perpendicular to the direction (that is, the pin contact 11
Although who diameter) _{W 2} is increased, the convex portion 21a, 2
The separation distance 1 b is larger than the thickness of the pin contact 11. Further, in this connector, in the direction orthogonal to the axial direction of the pin contact 11 (the pitch direction of the socket portion H), the tip position of the protrusion 21a protrudes beyond the tip position of the pin contact 11.

Next, the fitting connection of this connector, that is, the fitting connection between the pin side connector 1 and the socket side connector 2 will be described with reference to FIGS. 1 (a) and 1 (b). First, the pin side connector 1 and the socket side connector 2 are shown in FIG.
(A) and (b) as shown in FIG.
In this state, the insulators 10 and 20 of the connectors 1 and 2 are relatively approached. The tip of the pin contact 11 enters the socket portion H as if pressed toward the convex portion 21b by the guidance of the one convex portion 21a in the socket portion H of the socket contact 21.
When the fitting connection is continued, the tip of the pin contact 11 is guided by the other convex portion 21b and enters the inside of the socket portion H as if pressed toward the convex portion 21a. Finally, the end of the pin contact 11 contacts the inner surface of the socket portion H of the socket contact 21 while being pressed in opposite directions by two convex portions 21a and 21b as shown in FIG. Will be retained.

As a result, the pin contact 11 and the socket contact 21 are brought into conductive contact, and the fitting connection between the connectors 1 and 2 is completed. Incidentally, when the fitting connection is completed, the pin contact 11 is bent and deformed as shown in the figure.

The pin contact 11 used in this connector
In order to make the fitting connection with the socket contact 21 simple, the axial dimension of the pin contact 11 is made longer in order to have elasticity in the pitch direction.

By the way, as described above, the pin contact 11
When the dimension in the axial direction is long, the pin contact 11 tends to swing particularly in the pitch direction at the time of fitting connection. Therefore, it is also useful to prevent such a shake.

FIG. 2 shows the basic structure of a connector according to another embodiment of the present invention. FIG. 2A is a partial side sectional view, and FIG. 2B is a partial front sectional view. Indicates that
FIG. 1C shows the fitting and connection state in a partial front sectional view.

In this connector, a locator 3 serving as a movable positioning piece for positioning the fitting with the socket-side connector 2 is provided at a predetermined position near the end of the pin contact 11, and the locator 3 is provided near the end of the pin contact 11. The pin contact 11 is inserted into the opened through hole 31 to regulate the movable range of the pin contact 11.

That is, the locator 3 extends in a direction orthogonal to the axial direction of the pin contact 11 and regulates the movable range of the pin contact 11 in the orthogonal direction. Can be prevented. However, when the dimension of the pin contact 11 in the axial direction is short, the run-out is small, and the necessity of providing the locator 3 is reduced.

In each of the above-described embodiments, the pin contacts 11 of the pin-side connector 1 extend linearly in the axial direction. However, the pin contacts 11 may have a slight pitch even before the fitting connection. It can be used even if it is curved in the direction (direction orthogonal to the axial direction). Further, in each of the above-described embodiments, the case where two convex portions are formed on the inner surface of the socket portion H has been described. However, three or more convex portions may be provided. In this case, the different protrusions are pin contacts 11
In contrast, a contact holding force in a direction relatively different in a direction orthogonal to the axial direction of the pin contact 11 is applied.

On the other hand, in each of the above-described embodiments, the inner surface of the socket portion H is undulated. (Straight long hole)
Even in this case, the fitting connection can be made between the pin contact 11. However, in this case, pin contact 1
1 is bent, and at least two points at the end of the pin contact 11 bent on the inner surface of the socket part are different in contact holding force (two points) in a direction orthogonal to the axial direction of the pin contact 11. In this case, contact holding forces acting in opposite directions may be applied.

FIG. 3 shows a basic configuration of such a connector, that is, a connector according to another embodiment of the present invention. FIG. 3A shows a partial side sectional view of the connector, and FIG. b) is a partial side sectional view showing the fitting and connection state.

In this connector, the end of the pin contact 11 is bent at an obtuse angle in a direction perpendicular to the axial direction to form a bent portion 11a and a tip end 11b. In contact with the inner surface of the socket portion H '. That is, here, the dimension A between the bent point of the bent part 11a and the contact point of the tip part 11b in the direction orthogonal to the axial direction of the pin contact 11 is set to be larger than the distance B between the opposed inner surfaces of the socket part H '. are doing.

As a result, when the pin contact 11 is inserted into the socket portion H 'of the socket contact 21, the pin contact 11 enters the socket portion H' while the bending angle at the bent portion 11a is increased, and the pin contact 11 is bent. Since the bending point in the part 11a and the contact point in the tip part 11b are pressed on the inner surface of the socket part H 'in a state in which mutually opposite contact holding forces are applied in directions perpendicular to the axial direction of the pin contact 11, respectively. , The pin contact 11 and the socket contact 21 are brought into conductive contact.

By the way, in the case of the connector of this embodiment, when the dimension of the pin contact 11 in the axial direction is long, if the locator 3 is provided, the deflection at the time of the fitting connection can be effectively prevented.

[0028]

As described above, according to the connector of the present invention, the undulations for deforming and holding the pin contact on the inner surface of the socket portion fitted to the end of the pin contact of the pin-side connector in the socket contact are provided. And different convex portions which are separated from each other and form undulations are provided with contact holding forces in directions different from each other in the axial direction of the pin contact relative to the pin contact in directions orthogonal to the axial direction. Alternatively, the inner surface of the socket portion extends flatly in parallel with the axial direction of the socket contact, and at least two points on the inner surface of the socket portion extend in a direction orthogonal to the axial direction of the pin contact. In addition to having a curved configuration to provide contact holding forces in relatively different directions at The through hole of the positioning piece extending in the direction perpendicular to the direction inserts the pin contact and regulates the movable range of the pin contact in the orthogonal direction, so both connectors can be moved in the fitting direction with a small operating force The operability that can easily perform the fitting and disengagement operation is extremely excellent, and the overall size of the socket contact is particularly small because the socket contact is not structured to pinch the pin contact by its own clamping force Can be reduced. As a result, the pin contact of the pin-side connector is formed into a slender shape having a small width dimension, and the pitch width of each contact is reduced to form a simple configuration having high-density contacts. In this case, a configuration having a high practical value can be obtained as a multi-core connector in which the contacts are further densified.
