Description

Chip card connector

This creation relates to the design of a connector, and more particularly to a wafer card connector.

In the case of an existing mobile phone, a subscriber identity module (SIM), a chip card commonly referred to as a "SIM card", is inserted inside each mobile phone device to identify the user, and the SIM It is also able to store newsletter materials and phone numbers. In order to insert the SIM card into the mobile phone device, a general mobile phone device is provided with a chip connector in the circuit board inside the device for plugging in the SIM card, and reading and writing data to the SIM card. .

For a structure of a conventional wafer connector, for example, in the Patent No. M360469 of the Republic of China, a card connector is disclosed, comprising an insulative housing and a plurality of conductive terminals, the insulative housing comprising a body portion and an array of openings formed through the body portion unit. The plurality of conductive terminals are arranged in the insulating body, and each of the conductive terminals includes a fixing portion fixed in the insulating body and a contact portion in which the cantilever extending from one end of the fixing portion is disposed in the opening of the insulating body. The contact portion includes two extending arms respectively extending from two sides of the fixing portion, a connecting arm connecting the ends of the extending arms, and a resilient arm extending from the connecting arms obliquely between the extending arms. When the SIM card is inserted into the chip connector, the contact portion of the chip connector contacts the wafer of the wafer card to pass through The contact reads the data of the wafer card or writes the data to the wafer card.

Since the size of the chip card (SIM card) inserted by different mobile phone devices is also different, if a small-sized wafer card is inserted into the large-sized chip connector, the adapter card must be used to be able to have different sizes. The wafer card is inserted into a suitable wafer card connector.

Although a small-sized wafer card can be inserted into a large-sized wafer connector by a riser card, after a small-sized wafer card is assembled to the riser card, there is still a gap between the wafer card and the riser card. Moreover, the contact portion of the above wafer connector is extended by a resilient arm. Therefore, when a small-sized wafer card is inserted into or removed from the chip connector by the adapter card, there may be a case where the gap of the adapter card catches the contact portion of the chip connector. If the user improperly uses force, the contact portion may be damaged or deformed, and the wafer card cannot be inserted again.

Accordingly, the purpose of the present invention is to provide a wafer card connector that changes the structure of a plurality of terminals of the chip connector to solve the problem that the contact portion of the terminal is deformed by the gap of the conventional riser card.

The wafer card connector provided by the present invention includes a housing and a plurality of terminals. The housing has a partitioning portion, and a plurality of openings arranged in parallel and extending through the housing are formed on both sides of the housing; a plurality of terminals are respectively disposed in the plurality of openings of the housing, and the two ends of the terminals are respectively a first end and a second end, the first end is embedded in the partition of the housing, the second end is penetrated from the side of the housing and exposed to the housing, and each of the terminals is The first end and the second end respectively have convex contact portions.

The present invention further provides a wafer card connector including a housing and a plurality of ends child. The housing has a partitioning portion, and the two sides of the partitioning portion are formed with a plurality of openings arranged in parallel and extending through the housing, and the partitioning portion has a blocking piece corresponding to each of the openings, and the bottom of the blocking piece has a joint surface; The terminals are respectively disposed in the openings, and the two ends of the terminals are respectively a first end and a second end, the first end is movably coupled to the joint surface of the baffle, and the second end is from the The side of the housing penetrates and is exposed to the housing, and each of the terminals has a convex contact portion between the first end and the second end.

As can be seen from the above, since the contact portion of the present invention is formed between the two ends of the terminal, unlike the conventional wafer connector, the contact portion is extended by the cantilever. Therefore, when the wafer card is inserted into the wafer card connector of the present invention, the contact portion of the creation contacts the wafer of the wafer card, and since the contact portion of the creation is not extended by the cantilever, when the wafer is stuck or When removed, it will not cause damage or deformation of the contact.

However, the wafer card 12 is not often removed during the use habits of the general user. Therefore, the terminals 11" of the chip card connector 1" are pressed by the wafer card 12 for a long time, which easily causes damage and deformation of the terminal 11". .

Therefore, in the present embodiment, a buffer structure 114 is designed between the first end 111 of each terminal 11" and the contact portion 113, and between the second end 112 and the contact portion 113 to slow the wafer card 12 to the terminal. The pressing force generated by the contact portion 113 of the 11" further reduces the damage of the terminal 11". The buffer structure 114 of the present embodiment is a bent back structure, however, the buffer structure 114 of the back bending structure is only used as an embodiment. The description should not be limited thereto, and those skilled in the art can improve the buffer structure 114 to other forms according to the above description.

As can be seen from the above description, the wafer card connector 1, 1', 1" of the present invention changes the structure of the terminals 1, 11', 11", and the contact portion 113 is modified from the cantilever by the prior art. A convex contact portion 113 is formed between the first end 111 and the second end 112. Therefore, when the chip card 12 or the adapter card is inserted into the creation, the wafer card 12 or the adapter card does not get stuck when the card is inserted or removed, and the conventional technology is solved. The problem that the contact portion 113 is deformed or damaged is caused by the wafer card 12 or the riser card being caught in the contact portion 113 of the terminal 11 during the insertion or removal.

The above embodiments are merely illustrative of the principles of the present invention and its effects, and are not intended to limit the present invention. Anyone with ordinary knowledge in the field can do without violating this Modifications and variations of the above embodiments are made in the spirit and scope of the invention.
