TECHNICAL FIELD The present invention relates to a connector contact for electrically connecting a contact and a mating contact,
The present invention also relates to an electrical connector including a connector contact, and more particularly to a connector contact and an electrical connector that are applied to a plurality of contacts arranged at a narrow pitch or at high density and a mating contact.

2. Description of the Related Art A conventional electrical connector, as shown in FIG. 7, includes a socket side connector 30 and a pin side connector 40 fitted into the socket side connector 30.
The socket side connector 30 is the socket insulator 3
1 and a conductive socket contact 32 incorporated in the socket insulator 31.

An accommodating portion 33 for accommodating the socket contact 32 is formed in the socket insulator 31. In FIG. 7, the socket portion of the socket contact 32 is shown. The socket contact 32 is housed in the housing portion 33, and a holding portion (not shown) is held by the socket insulator 31. The socket portion has a pair of cantilever-shaped contact spring pieces 34 facing each other. The distance between the pair of contact spring pieces 34 is narrowed slightly as they extend to the tip side, and the contact portion 3 is provided near the tip portion.
5 and a guide portion 36 that is bent toward the tip side of the contact portion 35 in a wide mouth shape.

A through hole 37 for inserting a conductive pin contact 42 whose one end side is held by a pin insulator 41 of a pin side connector 40 is formed in a wall portion of the socket insulator 31 facing the guide portion 36. Has been formed.

When the pin contact 42 is inserted into the accommodation portion 33 through the through hole 37 of the socket insulator 31, the tip of the pin contact 42 is pushed between the contact portions 35 of the contact spring piece 34 while being guided by the guide portion 36.
The contact spring pieces 34 have spring forces in directions toward each other and hold the inserted pin contact 42. Therefore, the contact portion 35 of the contact spring piece 34 and the pin contact 42 are held.
And are electrically connected.

[0006]

However, when the pin contact 42 is inserted between the contact spring pieces 34, the guide portion 36 has an X dimension outside so that the pin contact 42 is deformed more than the outer dimension A of the socket contact 32. Since the width greatly opens, the dimension Y of the accommodating portion 33 must be set large to accommodate this deformation, and the outer dimension of the socket insulator 31 must also be set large.

Further, in the electrical connector in which the socket contacts 32 and the pin contacts 42 are arranged at a high density and a narrow pitch, the wall thickness dimension of the socket insulator 31 and the pin insulator 41 is made small to be miniaturized. However, when high-frequency characteristics are required, the shape of the transmission path becomes complicated and it becomes difficult to adjust the characteristic impedance.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to make a connector contact which can be applied to contacts arranged at a narrow pitch or high density and a mating connector uniform, and to make the outer shape of the connector contact uniform, thereby simplifying the connector structure. An object of the present invention is to provide an electrical connector capable of achieving the above.
