Description

Technical Field

[0001] The present invention relates to the technical field of communication card installation components, and in particular to a connector with a locking function. Background Art

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

[0003] Existing SIM card connectors have the following drawbacks: To prevent the tray from accidentally being ejected, potentially causing the connector terminals to fall out of contact with the SIM card contact pads and preventing the card from being read, conventional practices employ spring clips on one or both sides of the metal housing that interact with corresponding stop structures on the tray to limit the position of the tray. This design provides weak locking force for the tray, making it inadequate for use in high-vibration environments. Furthermore, the metal spring clips easily wear the tray during insertion and removal, reducing the locking force and shortening its service life. Therefore, we propose a connector with a locking function. Summary of the Invention

[0004] The main purpose of the present invention is to provide a connector with a locking function to solve the problem that the SIM card connector may not be able to read the card when the card tray is ejected when used in a vibrating environment, increase the service life of the card tray, and make the length and width of the connector smaller, which can effectively solve the problems in the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A connector with a locking function includes a plastic body, a signal terminal and a detection terminal integrally formed on the surface of the plastic body, a push rod groove horizontally opened on the side of the plastic body, a hardware shell clamped on the top of the plastic body, and a locking assembly disposed between the plastic body and the hardware shell, including:

[0007] Push rod: installed inside the push rod slot and with a push portion integrally formed at the end, a locking spring is welded on the side of the push rod, and the locking spring is provided with a resisting portion close to the end of the push portion that abuts against the surface of the push portion, and a linkage portion is integrally formed at the end of the push rod away from the push portion;

[0008] The card holder locking spring piece resistance part is arranged on the side of the plastic body facing the push rod, corresponding to the position of the locking spring piece.

[0009] Furthermore, it also includes a card tray, which is inserted between the plastic body and the hardware shell and a SIM card is inserted inside the card tray, and the surface of the SIM card is provided with contact pads corresponding to the positions of the signal terminals; the inside of the card tray is used to insert the SIM card, and the card tray plays a supporting role and carries the SIM card and is inserted between the plastic body and the hardware shell. After being inserted into place, the signal terminal fits perfectly 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. An assembly hole connected to the assembly shaft is opened inside the ejector rod, and a protrusion is integrally formed on the top of the ejector rod surface; 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 the surface of the hardware shell, increases the friction between the ejector rod and the hardware shell, and maintains 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, a card holder locking spring is provided on the side of the hardware shell at a position corresponding to the card holder locking spring slot, and a card holder locking spring resistance portion corresponding to the position of the card holder locking spring is provided on the side of the card holder; on the side of the plastic body away from the push rod, the card holder locking spring cooperates with the card holder locking spring resistance portion to play an auxiliary fixing role.

[0012] Furthermore, a limiting hole is opened horizontally on the top of the hardware shell, and a limiting boss is integrally formed on the top of the push rod and inserted into the limiting hole; the limiting boss on the top of the push rod is inserted into the limiting hole, and the limiting hole acts as a movement limiter for 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; a pin is conveniently inserted through the pin hole to eject the card holder.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the plastic body and the hardware shell cooperate to form the main structure of the connector, and 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 the card tray and the card tray, thereby reducing the wear of the card tray. When the card tray is locked, the tip of the locking spring resists the resisting part of the card tray locking spring, and the locking spring is not easy to deform, which increases the locking force, solves the problem that the card tray may be ejected and the card cannot be read when the SIM card connector is used in a vibrating environment, and increases the service life of the card tray. The locking spring is produced by folding the hardware in half, and the resisting part is designed at the end to fit the pushing part, which can prevent the pushing part from deforming. At the same time, the connector adopts an integrated The type terminal designs the signal terminal and the detection terminal together, and generates a signal for detecting whether the SIM card is inserted by simultaneously contacting the contact pad of the SIM card, so that the length and width of the connector can be made smaller. The ejector rod can be deflected around the assembly axis, and its end cooperates with the linkage part of the push rod to achieve linkage. The convex structure fits the surface of the hardware shell, increases the friction between the ejector rod and the hardware shell, and maintains the stability of the ejector rod. On the side of the plastic body away from the push rod, the card holder locking spring piece cooperates with the card holder locking spring piece resistance part to play an auxiliary fixing role. The limiting boss on the top of the push rod is inserted into the limiting hole. The limiting hole limits the movement of the limiting boss, thereby limiting the movement range of the push rod.

[0028] Push rod 3: It is installed inside the push rod groove 103 and has a push part 301 integrally formed at the end. A locking spring 304 is welded on the side of the push rod 3 and the locking spring 304 is provided with a resisting part 302 close to the end of the push part 301 that contacts the surface of 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.

[0029] Among them, it also includes a card tray 5, which is inserted between the plastic body 1 and the hardware shell 2, and a SIM card 503 is inserted inside the card tray 5. The surface of the SIM card 503 is provided with a contact pad 504 corresponding to the position of the signal terminal 101; the interior of the card tray 5 is used to insert the SIM card 503, and the card tray 5 plays a supporting role and carries the SIM card 503 and is inserted between the plastic body 1 and the hardware shell 2. After being inserted into place, the signal terminal 101 is just in contact with the contact pad 504 to ensure signal transmission.

[0030] Among them, the surface of the plastic body 1 is integrally formed with an assembly axis 4 at a position away from the insertion end of the SIM card 503, and is movably connected to the ejection rod 401 through the assembly axis 4. The ejection rod 401 is provided with an assembly hole 402 connected to the assembly axis 4, and the top of the surface of the ejection rod 401 is integrally formed with a protrusion 403; the ejection rod 401 can deflect around the assembly axis 4, and its end cooperates with the linkage part 303 of the push rod 3 to achieve linkage.
