Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connector. More specifically, the present invention relates to a connector used for electrical connection with a terminal of a card-like body such as an industrial card or a printed circuit board, in which a large number of terminals are arranged in parallel near the edge.

[Conventional technology and its problems]

Conventionally, an example of a card-shaped body in which a large number of terminals are provided in parallel near the edge is a printed circuit board, and this connector is provided with, for example, a large number of leaf spring-like contacts biased. The connection is mainly made by pushing the card-like body against the urging direction of the contacts. In the case of this type of connector, the elasticity of the contacts must be made strong to a certain extent to ensure the connection with the terminals of the card-like body, and considerable force is required when inserting and removing the connection. It is.

On the other hand, in recent years, there has been active development of 0-cards (9-cards in which an IC is embedded in a card-like thin plate and various types of information are stored therein).

In the case of the C-card, etc., it is normally removed from the connector and used by connecting it to the connector as necessary, so the connection and disconnection are repeated many times. For applications such as IC cards, etc.,
In the conventional structure in which a card-like body is press-fitted between elastic contacts as mentioned above, the terminals of the card-like body are rubbed each time they are connected to and disconnected from the contact, causing rounding, and the life of the terminals being shortened due to abrasion of the terminals. This is a major problem, and in practice, the use of this type of connector for IC cards is restricted due to the problems described above, and its use is limited.

In this plan, when the card-like object was inserted, the terminals of the connector were in an open state, and when the card-like object was inserted into the connector, the suppression of the contacts that had been kept in the suppressed state was removed, and the contacts were turned into the card-like state. The terminals of the card-like body were covered with Kasumi ±9, and the contacts were pressed against the terminals of the card-like body by external force. A so-called Z-PI (zero insert force type) connector is also being developed.

However, to date, no fully satisfactory connector has been found.

[Structure of the invention]

The inventors of the present invention conducted various studies to solve the problems of conventional connectors as described above, and found that by combining a contact pressing member with a special structure and a contact, the connection can be ensured and a card-shaped connector can be used. We succeeded in developing a two-work P-type connector that does not damage the terminals of the terminals, and completed the present invention.

That is, the gist of the present invention is to provide a connector for receiving a card-like body having a large number of terminals arranged in parallel near the edge thereof and for making electrical connections with each of the large number of terminals. A base housing in which a large number of parallel telepathic contacts are provided in a cantilevered manner at positions corresponding to the terminal positions of the body; a cover housing that covers the outside of the base housing and is provided with a card insertion slot; It consists of a pressing member in which two plate-shaped bodies provided between the contacts and the plate are combined with a hinge structure, and the pressing member has a contact portion with the inserted card, and is pressed when the card is inserted. Due to the pressure, the hinge structure bends toward the contact on the base housing, presses the contact, and establishes an electrical connection between the contact and the terminal on the card-like body.
(c) The connector is specially designed to have a release mechanism in the pressing member that bends the hinge structure in the opposite direction to the contact and releases the pressing force on the contact.

An example of the connector of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of an example of the connector of the present invention, and FIG. 2 is a sectional view taken along the line A in FIG. FIG. 3 is a sectional view taken along line B-B in FIG. 1, where (a) is before ejection, tb
) is the state after being ejected, and FIG. Z is an exploded perspective view of the connector shown in FIG. 1.

In the figure / is the connector, ko is the IC card, 3 is the base housing, 4t is the contact, ! is the cover housing, O is the card insertion slot, and 7 is the pressing member.

7', 7' are plate-like bodies constituting the pressing member 7, l is a card contacting part, and ? 10 is an eject cam, 10 is an eject lever, // is an end block, /2 is a spring percentage, and 13 is a connecting portion.

The connector of the present invention is used for connection with a card-like body having a terminal at the edge, such as a card-like card as shown in the figure.

The card-shaped body shown in the figure is an IC card, and the following explanation will be made using this IC card. For these 10 cards,
The terminals are not provided at the extreme end of the IC card, but at the slightly inner edge.

Moreover, this terminal is slightly recessed from the surface of the C-card λ, and this structure prevents the terminal from being damaged by touching it with fingers or being rubbed by other objects. It is prevented.

The connector of the present invention generally has a base housing 3, a card insertion slot 6, a cover housing J that covers the outside of the pace housing 3, a contact piece D, and a cover housing. and the contact between the contact element and the terminal.

It consists of a pressing member 2 having a rounded hinge structure for detachment and a release mechanism for releasing the pressing force of the pressing member against the contactor.

As shown in FIG. 9, a large number of contacts are provided on the base housing 3 in a cantilevered manner.

The position of this contactor is aligned with the position corresponding to the terminal provided on the inserted card-like body (work 0 card 2),
If the IC cart has terminals only on one side, it goes without saying that the contacts may only be provided in one row, either the top or the bottom.

The pace housing 3 is accommodated in the cover housing together with the contact piece, and between the contact piece of the pace housing 3 and the cover housing - ζ is such that the plate-shaped bodies 7' and 7'' are on the same side edge. A pressing member 7 having a nine-hinged structure and abutted against each other is provided.

As shown in FIG. One end of the card is brought into contact with the card abutting part t provided extending from the connector towards the center of the connector/.By further pushing the IC card, a pressing force is applied and the hinge part is brought into contact with the center of the connector/. It springs back into a bulged shape and becomes bent.At this time, as shown in Fig. 2+b), the bent part of the pressing member 7 presses the contact piece DA to curve it, and the protruding shape of the contact piece DA is bent. The parts are pressed against the terminals of the IC card to make the electrical connection.

A large number of partition plates are provided on the sides of the plate-shaped bodies 2', 2'' that constitute the pressing member 2 facing the contactors in order to prevent short-circuits between adjacent contactors. In particular, the corners of the partition plate provided on the plate-like body 7"
If the terminal of the C cart is connected to the corner of the recess provided, for example, if you try to pull out the C cart in this state.

It is in a state where it cannot be pulled out. By providing such a connecting portion /3, it is possible to prevent the work C card λ from being inadvertently pulled out.

When removing the IC cartco, please refer to Figure 3 (a) (b)
As shown in FIG. 2, the tongue-shaped portion provided at the side end of the plate-shaped body 2'' is pushed outward by pushing in an eject cam 9 having a tapered surface, and the hinge portion is rebound to release the tongue. This is done by setting the release mechanism to the position shown in Figure 3(b) (Figure 1(a)).The figure shows the mechanism of the eject cam and the suppressing eject lever, but this release mechanism is not limited to the method shown in the figure. For example, a mechanism such as pressing the card contact portion in the opposite direction is also applicable.

Note that // in the figure is an end block, which is fixed to the cover housing with screws or the like, integrates the parts, and has a mounting part and the like for fixing the present connector 7 and the equipment to be used.

In addition, the spring/co is used to return the eject cam.Although the above explanation was made using an IC card, the connector of the present invention is not limited to use only with IC cards. It can be well used as a test connector, etc.

Alternatively, in an IC card or the like, a connector may be provided with only one of the terminals provided on one side.

〔Effect of the invention〕

In the connector of the present invention, the contacts inside the connector are in an open state when accepting a card-like object, so there is no resistance when inserting the card-like object, and the card-like object can be inserted smoothly. It has the advantage that the edge of the body will not be damaged due to friction with the contact, and is light.

Since the contactor is suppressed by a pressing member made of two hinge-like plates, it is structurally simple and less likely to break down, making it an ideal connector for use in C-card readers, etc. It is very effective in practice.
