Abstract

PURPOSE:To provide a connector with multi-pins or thin the connector by forming connector housings and contacts in triangular shapes. CONSTITUTION:A plural number of triangular connector housings 2 are arranged in such a way to line the corner and the straight part alternately in the width direction of the main body 1 of a connector and contacts 3 are arranged in the connector housing 2. The above-mentioned constitution can make the pitch among connector housing units smaller so as to increase the number of the connector pins 4 or decrease the thickness of the connector.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card connector suitable for increasing the number of pins or making it thinner.

[0002]

2. Description of the Related Art FIGS. 4 to 6 are views showing a conventional IC card connector, in which 1 is a connector body attached to an IC card (not shown), 2 is a connector housing attached to the connector body 1, and FIG. Reference numeral 3 denotes a contact having a square shape as shown in FIG. 5 or a circular shape as shown in FIG. 6, which is press-fitted into the connector housing 2, and 4 denotes a connector pin on the system device side (not shown) that contacts the contact 3. .

Here, the contacts 3 press-fitted into the connector housing 2 are arranged in a straight line in the horizontal direction as shown in FIG. 4 when viewed in the axial direction, or in a staggered arrangement. In this conventional device, when an IC card (not shown) is mounted on the system device side (not shown), the connector pin 4 and the contact 3 are engaged with each other, and a normal operation is performed.

[0004]

Since the contactor 3 of the connector housing in the conventional IC card connector is constructed as described above, when the thickness of the connector is reduced or the number of pins is increased, the space between the connector housings is reduced. There was a problem that the interval between the two became narrower.

The present invention has been made in order to solve such a problem, and the pitch between the connector housings is changed without changing the wall thickness between the contactors to increase the number of pins or to reduce the thickness of the connector. With the goal.

[0006]

According to an IC card connector of the present invention, a plurality of triangular connector housings are arranged in a width direction of a connector body of the IC card so that corner portions and straight portions are alternately arranged. The contacts are arranged in the connector housing.

[0007]

In the connector according to the present invention, since the connector housing and the contactor are formed in a basic shape of a triangle so that the corner portions and the linear portions are alternately arranged in the width direction of the connector body, the arrangement intervals of the connector housings are reduced. It can be made narrower, and the number of pins can be increased or the thickness can be reduced.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
I will explain based on. That is, in FIG. 1 and FIG. 2, reference numeral 2 denotes a regular triangular connector housing in which corner portions and straight portions are alternately arranged in the width direction in the connector body 1, and 3 is press-fitted into the connector housing 2. It is a triangular contactor as shown in FIG. Since the other structures are the same as those of the conventional structure shown in FIGS. 4 to 6, description thereof will be omitted.

In such a structure, the connector pin 4 and the contact 3 are brought into contact with each other and a predetermined action is performed by mounting the IC card on the system device side in a manner similar to the conventional one.

The connector housings 2 may be arranged in a staggered manner as shown in FIG. 3 in order to make the connector thinner.

As described above, the number of pins can be increased or the thickness of the connector can be reduced by reducing the pitch between the connector housing portions without changing the wall thickness between the housings according to the present invention.

[0012]

As described above, in the IC card connector according to the present invention, it is possible to increase the number of connector pins or reduce the thickness of the connector by forming the connector housing and the contact in a triangular shape.
