The present invention proposes a horizontal SIM card holder, the horizontal SIM card holder includes a SIM card connector 1, and the SIM card connector 1 is fixedly connected to a circuit board (not shown in the figure) inside the mobile phone and electrically connected to it. At the same time, the SIM card connector 1 is also in electrical contact with the SIM card 2 arranged inside the horizontal SIM card holder. Here, the SIM card connector 1 includes a plurality of split connectors 10, and these split connectors 10 are arranged in sequence along the length direction of the SIM card 2. Here, each split connector 10 has a function for electrically contacting the SIM card. The terminals 11 of the card 2, and a plurality of terminals 11 between two adjacent split connectors 10 are arranged at intervals along the width direction of the SIM card 2 and arranged in a staggered manner.

Using the above-mentioned horizontal SIM card holder in the mobile phone has the following characteristics: by dividing the SIM card connector 1 into a plurality of split connectors 10 arranged in sequence along the length direction of the SIM card 2, and connecting each split connector 10 Corresponding terminals 11 are arranged on the top, and a plurality of terminals 11 between two adjacent split connectors 10 are arranged at intervals along the width direction of the SIM card 2 and arranged in a staggered manner, so that the SIM card 2 can be inserted into the SIM card holder laterally, At the same time, the external dimension of the SIM card connector 1 can be made small enough, thereby reducing the mobile phone space occupied by it, improving the utilization rate of the mobile phone space, and facilitating the thin and light design of the mobile phone.

The above-mentioned split connector 10 includes an insulating body 110 and a terminal 11. The bottom end of the terminal 11 is buried and fixed in the insulating body 110, and the upper end of the terminal 11 protrudes upwards obliquely relative to one side of the insulating body 110. Here, the terminal 11 The bottom end is embedded in the insulating body 110 by injection molding. The insulating body 110 is a plastic structure. Such a molding method helps to improve production efficiency. Of course, according to actual conditions and needs, in other embodiments, the insulating body 110 Other insulating materials can also be used, and the terminal 11 can also be fixedly connected to the insulating body 110 in other ways.

The above-mentioned terminal 11 includes a fixing part 111, a welding leg 112 and an elastic arm 113, wherein the fixing part 111 is fixed in the above-mentioned insulating body 110, and the fixing part 111 is a sheet-shaped conductive metal, such as an aluminum sheet, a copper sheet, etc. , here, the fixing part 111 is embedded in the plastic insulating body 110 by injection molding; the welding feet 112 are connected to the edge of the fixing part 111, and there are a plurality of welding feet 112 distributed on the edge of the fixing part 111 In different positions, the soldering leg 112 and the fixing part 111 can be an integral piece, of course, can be a separate part. The soldering leg 112 is used to weld and fix the circuit board and form an electrical connection; The edge protrudes outwards and extends obliquely upwards. The elastic arm 113 provides elasticity for the entire terminal 11. Of course, the elastic arm 113 is also conductive metal. In addition, a contact portion 1131 is formed on the top of the elastic arm 113. The contact portion 1131 is used to make electrical contact with the above-mentioned SIM card 2, that is, when the SIM card 2 is inserted into the above-mentioned SIM card holder, the SIM card 2 presses down each terminal 11 of the SIM card connector 1, specifically, the SIM card 2 presses down on each terminal 11 of the SIM card connector 1. The elastic arm 113 of each terminal 11 is pressed, and the contact portion 1131 of the elastic arm 113 is in contact with the corresponding gold finger (ie, an electrical contact) on the SIM card 2 to form an electrical connection.

In addition, a connecting arm 114 is also provided between the fixing part 111 and the elastic arm 113 of the above-mentioned terminal 11. The connecting arm 114 is a transverse elastic arm, which is arranged laterally relative to the fixing part 111, that is, perpendicular to the fixing part 111. Here The connecting arm 114 is also conductive metal, such as aluminum sheet, copper sheet, etc. Specifically, one end of the connecting arm 114 is connected to one side edge of the fixing part 111, and the other end of the connecting arm 114 is connected to the bottom of the elastic arm 113. In this way, the connecting arm 114 and the elastic arm 113 provide elasticity for the entire terminal 11. In this embodiment, the entire terminal 11 is integrally formed. Of course, in other embodiments, according to actual conditions and needs, the terminal 11 can also be for each composed of separate parts.

The above-mentioned elastic arm 113 is in the shape of an inverted V, which is formed by crossing two straight arms obliquely. The pressure of the straight arm length direction of the elastic arm 113 is used to prevent the elastic arm 113 from being deformed and damaged, resulting in poor contact with the SIM card 2 . And, since the above-mentioned SIM card connector 1 includes a plurality of split connectors 10, and these split connectors 10 are arranged sequentially along the length direction of the SIM card 2, a plurality of split connectors 10 between two adjacent split connectors 10 The terminals 11 are arranged in a staggered manner. Here, the staggered arrangement refers to the positional relationship formed between the terminals on one split connector and the terminals on the split connector adjacent to the split connector. Then, the elastic arms 113 on the plurality of terminals 11 are also arranged in a staggered manner. Since each elastic arm 113 is in an inverted V shape, the staggered arrangement of the plurality of terminals 11 is more compact, that is to say , the arrangement between the plurality of split connectors 10 is more compact, so that the dimensions of the SIM card connector 1 can be made small enough, thereby reducing the mobile phone space occupancy rate of the entire SIM card holder and saving the space of the mobile phone. Of course, in other embodiments, according to actual conditions and requirements, the elastic arm 113 may also be in other shapes, and is not limited to a V-shape. In this embodiment, the roots of the two straight arms of the elastic arm 113 are respectively connected with a connecting arm 114, that is, a terminal 11 includes an elastic arm 113, two connecting arms 114, a fixing portion 111 and a plurality of welding legs 112, the entire terminal 11 is integrally formed.

The contact portion 1131 at the top of the elastic arm 113 is preferably spherical or spherical-like. When the SIM card 2 is inserted into the SIM card holder, the front end of the SIM card 2 is in contact with the contact portion 1131 of the terminal 11. Since the contact portion 1131 is spherical or spherical, the insertion of the SIM card 2 It is smoother, and when the SIM card 2 is fully inserted into the SIM card holder, the spherical or spherical-like contact portion 1131 can effectively make good contact with the golden fingers (ie, electrical contacts) on the surface of the SIM card 2 . Of course, in other embodiments, according to actual conditions and needs, the above-mentioned contact portion 1131 may also be in other shapes, such as a slope shape and the like.
