Description

Technical Field

[0001] This utility model relates to the field of card holder connector technology, and specifically to a card tray type card holder connector. Background Technology

[0002] Existing card slot connectors have a bottom surface entirely made of molded plastic. Due to limitations in plastic injection molding processes and plastic strength, the bottom surface thickness of the card slot generally needs to be above 0.40mm, which prevents the card slot connector from being designed to be thinner.

[0003] Therefore, we propose a card holder connector. Utility Model Content

[0004] The main purpose of this utility model is to provide a card tray type connector. The card tray sliding rail is made of metal, and the metal part of the card tray sliding rail and the metal terminal are integrated into one design, which significantly reduces the overall thickness of the connector and meets the needs of miniaturization and thinning of electronic devices; it can effectively solve the problems in the background technology.

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

[0006] A card tray connector includes a card tray body, a pull rod, a plastic body, and a metal housing. The upper surface of the plastic body is provided with a slot, and the metal housing is fastened to the upper surface of the plastic body. The upper surface of the metal housing is provided with grooves for installing locking springs on both sides of the plastic body. The upper surface of the plastic body is provided with card tray locking spring slots on both sides that are adapted to the bottom end of the locking springs. The upper surface of the plastic body is also provided with a push rod mounting slot for installing a push rod on one side.

[0007] The bottom surface of the slot is provided with card tray sliding rails on both sides, which are adapted to the card tray body. Two sets of card tray sliding rails are arranged in parallel. The bottom surface of the slot is also provided with an assembly groove for installing the welding part of the hardware terminal and an installation hole for installing the hardware terminal. The assembly groove and the installation hole are located between the two sets of card tray sliding rails.

[0008] One end of the card tray body is inserted into the slot. The card tray body is located between the plastic body and the metal shell. A pull rod is fixedly connected to the end of the card tray body away from the slot. A limiting groove for installing the ejector rod is provided on the upper surface of the plastic body away from the pull rod. The ejector rod is sleeved on the assembly shaft at the center. The bottom end of the assembly shaft is fixedly connected to the inner wall of the bottom end of the limiting groove. The ejector rod is rotatably connected to one end of the plastic body. One end of the ejector rod is located in the push rod mounting groove and contacts one end of the push rod. The push rod has a bent part at the end away from the ejector rod, and a positioning hole is provided on the side of the bent part near the pull rod. The pull rod has an insertion hole for the ejector pin to pass through at the end near the positioning hole.

[0009] The upper surface of the card tray body is provided with a SIM card mounting hole for placing the SIM card body, and the SIM card mounting hole is connected to the slot.

[0010] By adopting the above technical solution, the card tray sliding rail is made of metal material, and the metal thickness can be reduced to 0.08mm. Furthermore, the metal part of the card tray sliding rail and the metal terminal are designed as a single unit. While ensuring structural strength, the overall thickness of the connector is significantly reduced, meeting the needs of miniaturization and thinning of electronic devices.

[0011] Specifically, the slot, push rod mounting groove, and push rod are all located inside the metal housing, and the push rod is slidably connected to the plastic body.

[0012] Specifically, the upper surface of the metal housing is provided with a through hole that matches the top of the assembly shaft at the end away from the pull rod. The ejector rod is located between the plastic body and the metal housing, and the ejector rod is located at one end of the card holder body.

[0013] Specifically, the SIM card body is horizontally embedded in the SIM card mounting hole, and the SIM card body is engaged with the card tray body.

[0014] Specifically, the SIM card body has metal terminal contact parts at the corresponding metal terminals on the lower end, and multiple sets of metal terminal contact parts and metal terminals are provided.

[0015] Specifically, one end of the ejector pin passes through the insertion hole and is inserted into the positioning hole.

[0016] The beneficial effects of this utility model are as follows: The card tray type connector described in this utility model uses metal for the card tray sliding rail, and the metal thickness can be reduced to 0.08mm. Moreover, the metal part of the card tray sliding rail and the metal terminal are designed as an integral unit, which significantly reduces the overall thickness of the connector while ensuring structural strength, thus meeting the requirements of miniaturization and thinness of electronic devices. The linkage structure composed of the ejector rod and the push rod, together with the ejector pin operation, makes the card tray removal process simple and effortless. The parallel design of the card tray sliding rail ensures the stability of the card tray during insertion and removal. Attached Figure Description
