Description

Technical Field

[0001] This utility model relates to the technical field of communication card mounting components, and in particular to a connector with a locking function. Background Technology

[0002] The SIM card slot connector is a key component in mobile communication devices used to fix and connect SIM cards. It mainly realizes the electrical connection and data transmission between the device and the SIM card, ensuring the normal operation of mobile communication functions.

[0003] Existing SIM card slot connectors have the following drawbacks: For SIM card slot connectors with card trays, to prevent the connector terminals from detaching from the SIM card contact pad and failing to read the card due to abnormal card tray ejection, the conventional approach is to design spring clips on one or both sides of the metal casing to cooperate with the corresponding stop structure of the card tray to limit the card tray. This design provides insufficient locking force for the card tray, which cannot meet the requirements of the device in a strong vibration environment. Moreover, the metal casing spring clips are prone to wear on the card tray during insertion and removal, resulting in reduced locking force and affecting the lifespan of the card tray. Therefore, we propose a connector with a locking function. Utility Model Content

[0004] The main purpose of this utility model is to provide a connector with a locking function, which solves the problem that the SIM card connector may eject and fail to read the card when used in a vibrating environment, increases the service life of the card tray, and allows the connector to be made smaller in length and width, effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A connector with a locking function includes a plastic body, on the surface of which signal terminals and detection terminals are integrally formed. A push rod groove is horizontally formed on the side of the plastic body. A metal housing is snapped onto the top of the plastic body. A locking assembly is provided between the plastic body and the metal housing, including:

[0007] Push rod: It is installed inside the push rod groove and has a push part integrally formed at the end. A locking spring is welded to the side of the push rod and a resisting part that abuts against the surface of the push part is provided at the end of the locking spring near the push part. A linkage part is integrally formed at the end of the push rod away from the push part.

[0008] Card holder locking spring resisting part: It is located on the side of the plastic body facing the push rod, corresponding to the position of the locking spring.

[0009] Furthermore, it also includes a card tray, which is inserted between the plastic body and the metal casing, and a SIM card is inserted inside the card tray. The surface of the SIM card is provided with a contact pad corresponding to the position of the signal terminal. The inside of the card tray is used to insert the SIM card. The card tray plays a supporting role and carries the SIM card to be inserted between the plastic body and the metal casing. After being inserted into place, the signal terminal is exactly in contact with the contact pad to ensure signal transmission.

[0010] Furthermore, an assembly shaft is integrally formed on the surface of the plastic body away from the SIM card insertion end, and an ejector rod is movably connected to the assembly shaft. The ejector rod has an assembly hole inside that connects to the assembly shaft, and a protrusion is integrally formed on the top surface of the ejector rod. The ejector rod can deflect around the assembly shaft, and its end cooperates with the linkage part of the push rod to achieve linkage. The protrusion structure fits against the surface of the metal shell, increasing the friction between the ejector rod and the metal shell, and maintaining the stability of the ejector rod.

[0011] Furthermore, a card holder locking spring slot is provided on the side of the plastic body away from the push rod slot, and a card holder locking spring plate is provided on the side of the hardware housing at a position corresponding to the card holder locking spring plate slot. A card holder locking spring plate resisting part is provided on the side of the card holder corresponding to the position of the card holder locking spring plate. On the side of the plastic body away from the push rod, the cooperation between the card holder locking spring plate and the card holder locking spring plate resisting part plays an auxiliary fixing role.

[0012] Furthermore, a limiting hole is formed in the horizontal direction at the top of the hardware housing, and a limiting boss is integrally formed at the top of the push rod and inserted into the limiting hole; the limiting boss at the top of the push rod is inserted into the limiting hole, and the limiting hole plays a role in limiting the movement of the limiting boss, thereby limiting the movement range of the push rod.

[0013] Furthermore, a pin hole is provided on the side of the end of the card holder; the pin hole facilitates the insertion of a pin to eject the card holder.

[0014] Compared with the prior art, this utility model has the following beneficial effects: The plastic body and the metal shell cooperate to form the main structure of the connector. The locking spring on one side of the plastic body is designed on the push rod, which can slide back and forth with the push rod, reducing the friction between it and the card tray and thus reducing the wear of the card tray. When the card tray is locked, the tip of the locking spring resists the card tray locking spring resisting part, the locking spring is not easy to deform, increases the locking force, solves the problem that the SIM card connector may eject the card tray and fail to read the card when used in a vibration environment, and increases the service life of the card tray. The locking spring is produced by metal folding method, and the resisting part is designed at the end to fit with the push part, which can prevent the push part from deforming. At the same time, the connector adopts a The integrated terminal combines the signal and detection terminals, generating a signal to detect whether a SIM card is inserted by simultaneously contacting the SIM card's contact pad. This allows for a smaller connector size. The ejector rod can deflect around the assembly axis, and its end engages with the linkage of the push rod to achieve linkage. The protrusion structure fits against the surface of the metal housing, increasing the friction between the ejector rod and the metal housing, maintaining the stability of the ejector rod. On the side of the plastic body away from the push rod, the cooperation between the card tray locking spring plate and the card tray locking spring plate resistance provides auxiliary fixation. The limiting boss at the top of the push rod inserts into the limiting hole, and the limiting hole limits the movement of the limiting boss, thereby restricting the range of motion of the push rod.

[0028] Push rod 3: Installed inside the push rod groove 103 and integrally formed with a push part 301 at the end. A locking spring 304 is welded to the side of the push rod 3 and a resisting part 302 that abuts against the surface of the push part 301 is provided at the end of the locking spring 304 near the push part 301. A linkage part 303 is integrally formed at the end of the push rod 3 away from the push part 301.

The surface of the SIM card 503 is provided with a contact pad 504 corresponding to the position of the signal terminal 101. The card tray 5 is used to insert the SIM card 503. The card tray 5 serves as a support and carries the SIM card 503 into the space between the plastic body 1 and the metal casing 2.
