The following describes the specific implementation of the present invention in more detail with reference to specific embodiments:

referring to fig. 1, fig. 2, fig. 3, and fig. 6, an embodiment of the present invention provides a SIM card device 10, which includes a SIM component 11 and a communication module 12.

The SIM component 11 includes a SIM card 111 and a circuit board 112 electrically and signal-connected to the SIM card 111, and the circuit board 112 is provided with an insertion part 1121; the communication module 12 is provided with a plug seat 121 connected with the plug part 1121 by signal, and the plug seat 121 is provided with a plug groove 1211 for detachably plugging the plug part 1121 therein. Based on this, the signal connection between the SIM component 11 and the communication module 12 can be realized by inserting the insertion part 1121 of the circuit board 112 into the insertion groove 1211 of the insertion seat 121 of the communication module 12; by pulling out plug portion 1121 from plug slot 1211, the signal connection between SIM module 11 and communication module 12 can be disconnected, which facilitates the operation of replacing or repairing SIM module 11 by an operator.

The insertion slot 1211 has a guide section 12111 and an insertion section 12112, and the width of the guide section 12111 is tapered in a direction toward the insertion section 12112, that is, the width of the guide section 12111 is tapered in a direction away from the insertion section 12112. Therefore, in the process of inserting the insertion part 1121 into the insertion slot 1211, the operator can quickly and accurately insert the insertion part 1121 into the guide section 12111, and then the insertion part 1121 is smoothly inserted into the insertion section 12112 under the guiding action of the guide section 12111, so that the operation of inserting the insertion part 1121 into the insertion slot 1211 can be conveniently, quickly and efficiently completed.

One of the plate surface of the insertion part 1121 and the groove wall of the insertion groove 1211 is convexly provided with a clamping protrusion 1122, and the other one of the plate surface and the groove wall of the insertion groove 1211 is concavely provided with a clamping groove 1212 in clamping fit with the clamping protrusion 1122. Based on this, by providing the clamping protrusion 1122 and the clamping groove 1212 which are in clamping fit with each other on the groove walls of the insertion part 1121 and the insertion groove 1211, in the process that an operator inserts the insertion part 1121 into the insertion groove 1211, under the limiting effect of the clamping groove 1212 on the clamping protrusion 1122, the insertion part 1121 and the insertion groove 1211 can be reliably inserted in an aligned manner, and the risk that the insertion part 1121 is offset relative to the insertion groove 1211 can be effectively reduced; after the plugging operation of the plugging portion 1121 into the plugging slot 1211 is completed, under the effect that the plugging slot 1211 limits the plugging portion 1121 and the clamping slot 1212 limits the clamping protrusion 1122 together, the risk of the plugging portion 1121 shifting relative to the plugging slot 1211 can be effectively reduced, so that the connection between the SIM component 11 and the communication module 12 is more stable and reliable, the stability, reliability and vibration resistance of the connection between the SIM component 11 and the communication module 12 are effectively improved, and the risk of signal interruption due to poor contact between the SIM component 11 and the communication module 12 in environments such as vibration is effectively reduced.

By adopting the above scheme, through the arrangement that the end part of the first pin 11231, which is far away from the body 1124 of the circuit board, protrudes out of the corresponding end part of the second pin 11232, in the process of inserting the inserting part 1121 into the inserting groove 1211, it can be ensured that the first pin 11231 is prior to the second pin 11232 to realize signal conduction, that is, it can be ensured that the GND pin is prior to the non-GND pin to realize signal conduction, so that the GND signal can be preferentially conducted to absorb static electricity generated in the SIM card device 10, and further interference of the static electricity on other signals is reduced, so that signal transmission between the SIM component 11 and the communication module 12 is more reliable and more stable, and the SIM card device 10 is ensured to operate more reliably and stably.

Referring to fig. 5, in the present embodiment, the first pins 11231 are longer than the second pins 11232 by 0.45-0.55 mm (mm).

By adopting the above-mentioned scheme, the arrangement that the first pin 11231 is 0.45-0.55 mm longer than the second pin 11232 effectively ensures that the first pin 11231 conducts signals preferentially to the second pin 11232 during the insertion of the plug portion 1121 into the plug slot 1211, and also effectively ensures that static electricity generated in the SIM card device 10 is effectively absorbed during the conduction of the GND signal preferentially to the non-GND signal.

Referring to fig. 5, in the present embodiment, the number of pins disposed on the two first gold fingers 1123 is the same.

By adopting the scheme, the number of the pins arranged on the two first golden fingers 1123 is the same, so that the consistency of signal conduction of the first golden fingers 1123 on the two sides is favorably ensured; in addition, it is also beneficial to achieve consistency of the two opposite sides of the insertion part 1121 in the thickness direction thereof, so as to reduce the restriction on the insertion direction of the insertion part 1121, and facilitate the operation of inserting the insertion part 1121 into the insertion groove 1211 quickly and efficiently.
