  The present invention relates to a user identification module connector, and more particularly to a connector with improved detection terminals and ground terminals on the user identification module connector.

  In the rapidly evolving technology era, consumer electronic products such as digital cameras, PDAs and mobile phones are already light and thin. As the penetration rate has been increasing day by day, mobile phones have provided people with speed and speed of communication in business or life. In addition to the functions of call communication and message transmission, the mobile phone is now available on the Internet and email. Multi-functions such as sending and receiving, watching TV programs, digital cameras, etc., have further matched the demand for use in modern business and lifestyle.

  In various mobile phones, a user identification module card (SIM card) is mounted, which identifies the user's identity and data, and has a conductive surface on the SIM card. All mobile phones are equipped with a SIM card connector so that the mobile phone can be quickly connected to the SIM card. The mobile phone is in electrical contact with the conductive surface of the SIM card to complete the confirmation procedure and provide.

Since the volume of the SIM card used in the cellular phone is small, the volume of the SIM card connector to be used is also small. When inserting the SIM card into the connector, it is difficult to confirm whether the SIM card has been securely inserted into the fixed position. FIG. 1 is a schematic diagram of a prior art SIM card connector.
Conventionally, a detection terminal 901 is specially installed on one end of the SIM card connector 90, and when the SIM card is inserted into the SIM card connector 90, the SIM card is accurately inserted at a fixed position by contacting the detection terminal 901. It is determined whether it is. However, such an arrangement increases not only the volume of the SIM card connector 90 but also the cost.

  In view of the above problems, a main object of the present invention is to provide a user identification module connector, particularly a connector in which a detection terminal and a ground terminal are coupled.

According to the above object, the present invention includes a plurality of first terminals, a second terminal provided corresponding to the plurality of first terminals, and an insulating housing provided with each first terminal and each second terminal. Each of the first terminals and the second terminals includes a fixed part that forms a space, and a contact part that extends from the fixed part toward the space. The insulating housing forms a hollow area that exposes a plurality of each contact portion to the outside.
Among them, the user identification module connector is characterized in that a detection terminal is arranged in an arbitrary hollow area of the insulating housing, and the detection terminal extends from the detection fixing part to the working space. The detection fixing part is provided in the insulating housing, and the detection contact part and the contact part extending from the detection fixing part are jointly arranged and exposed in the hollow area of the insulating housing. .

  The user identification module connector provided by the present invention simplifies the design in which both the detection terminal and the ground terminal are arranged in the same hollow area, and the detection structure is further installed in the user identification module connector. This not only simplifies the space, but also reduces costs.

  Please refer to FIG. The user identification module connector has a plurality of first terminals 30 and a plurality of second terminals 32, and the second terminals 32 and the first terminals 30 are arranged in pairs. Among these, each 1st terminal 30 is formed from the fixing | fixed part 301 which forms space, and the contact part 303 extended | stretched from the fixing | fixed part 301 to the said space. Each second terminal 32 is also formed of a fixing portion 321 that forms a space and a contact portion 323 that extends from the fixing portion 321 to the space. The contact portion 303 of each first terminal 30 is connected to the fixing portion 301 and maintains a distance from the fixing portion 301. Similarly, the contact portion 323 of each second terminal 32 is connected to the fixed portion 321 and is spaced from the fixed portion 321.

In addition, the detection terminal 40 is arranged in the area of one first terminal 30. The detection terminal 40 includes a detection fixing portion 401 that forms a space and a detection contact portion 403 that extends from the detection fixing portion 401 to the space. The detection contact portion 403 is connected to the detection fixing portion 401 and is spaced from the detection fixing portion 401.
The number of the first terminals 30 and the second terminals 32 of the user identification module connector of the present invention is three (total of six), but the present invention limits the number of the first terminals 30 and the second terminals 32 disposed. Not what you want. In addition, in the first terminal 30 and the second terminal 32 of the present invention, the fixing portions 301 and 321 and the contact portions 303 and 323 are integrally formed, and the detection fixing portion 401 and the detection contact portion 403 of the detection terminal 40 are similarly integrated. Molded. Further, each of the fixing portions 301 and 321, the contact portions 303 and 323, the detection fixing portion 401 and the detection contact portion 403 has a specific geometric shape.

Referring to FIGS. 3A and 3B simultaneously, the insulating housing 20 has a plurality of hollow areas 201, while the first terminal 30, the second terminal 32 and the detection terminal 40 are disposed and housed in the insulating housing 20. The fixing portions 301 and 321 and the detection fixing portion 401 are covered to expose the contact portions 303 and 323 and the detection contact portion 403 to the hollow area 201.
Among these, the detection contact part 403 and any one contact part 303 'are exposed to the same hollow area 201'. Further, the solder portions 305, 325, and 405 are further extended on the first terminals 30, the second terminals 32, and the detection terminals 40, soldered to an external substrate (PCB), and the solder portions 305, 325, 405 is exposed on the outside 203 of the insulating housing 20.

Each of the contact portions 303 and 323 and the detection contact portion 403 has extended bent portions 3031, 3231 and 4031, and the contact portions 303 and 323 and the detection contact portion 403 exposed to the hollow area 201 of each insulating housing 20. Is protruded from the surface of the insulating housing 20, and contact portions 3033, 3233, 4033 are formed at the free ends of the bent portions 3031, 3231, 4031 and used for contact with an external SIM card (IC card or the like).
The insulative housing 20 of the present invention covers the first terminal 30, the second terminal 32, and the detection terminal 40 by insert molding, but the coupling method of the present invention is not limited to this. The insulating housing 20 is made of a polymer material, and the first terminal 30, the second terminal 32, and the detection terminal 40 are made of metal. Here, the outline of the hollow area 201 has a geometric shape, and is changed by the arrangement of the first terminal 30, the second terminal 32, and the detection terminal 40.
In addition, since the contact portion 323 and the detection contact portion 403 are disposed in the hollow section 201 ′, the size of the hollow section 201 ′ is larger than that of the other hollow section 201 and can accommodate two terminals. However, the size of the hollow areas 201 and 201 ′ is not limited in the present invention.

  Referring to FIG. 4, the user identification module connector of the present invention has seven terminals, which are a serial data input / output terminal A (serial data input / output), a programming voltage terminal B (programming voltage), and a detection terminal C (switch). ), A ground terminal D (power and signal ground), a clock signal terminal E (clocking signal), a reset signal terminal F (reset signal), and a potential terminal G (power voltage). Among these, the detection terminal C and the ground terminal D are both disposed in the same hollow area 201 '.

5A, on the SIM card (or IC card) 50, there are eight contact areas 501 (the normal mobile communication SIM card uses only six of these contact areas 501 and the remaining two preliminary contact areas 503. , 505 need not be used, and the six contact areas 501 will be described here). Of these, six contact areas 501 correspond to the respective terminals on the user identification module connector (that is, the contact portions 303 and 323 and the detection contact portion 403).
When the SIM card 50 is inserted (eg, SIM card slit of a mobile phone or a tablet), the contact area 501 is first a serial data input / output terminal A, a programming voltage terminal B, a ground terminal D, a clock signal terminal E, a reset signal. The six terminals of terminal F and potential terminal G are contacted. Next, referring to FIG. 5B, when the SIM card 50 is completely inserted, the contact area 501 located at the ground terminal D simultaneously contacts the detection terminal C and the ground terminal D, and both terminals form a circuit. .

The main purpose of these terminals to form a circuit is to detect whether an electronic product (for example, a mobile phone or a tablet) is clearly inserted into the SIM card slit, thereby detecting terminals C and ground terminals. The design in which both D are arranged in the same hollow area 201 ′ and the detection structure needs to be installed on the user identification module connector is simplified, not only the space of the wiring board (PCB) is simplified, but also the cost Savings are also possible.
In addition, it should be further emphasized that the present invention has a design in which both the detection terminal C and the ground terminal D are arranged in the same hollow region 201 ′, so that interference between signals is relatively low. And other terminals are not limited to the design in which they are arranged in the same hollow region 201, and will be described again.
Further, even if a change in the SIM card 50 contact area 501 in the future or an IC card or a credit card having a relatively large contact area (for example, the contact areas 503 and 505) is used, the user identification module connector of the present invention is used. Since the arrangement number of the hollow region 201, the first terminal 30, and the second terminal 32 can be changed according to the change, the present invention limits the arrangement number of the hollow region 201, the first terminal 30, and the second terminal 32. is not.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like that do not depart from the gist of the present invention.
