Abstract: An electrical connector comprises a housing with a cage, a plurality of terminals and a card ejecting mechanism. The cage and the housing are assembled and together define a slot that an electronic card can move in and out along an inserting direction. The card ejecting mechanism is provided to the slot and adjacent to a side wall defining the slot and can move back and forth between a work position and a ejecting position along the inserting direction. The card ejecting mechanism comprises a driving rod and a controlling rod pivotally connected to the driving rod. When the card ejecting mechanism is positioned in the work position the majority of the controlling rod is positioned in the slot and cannot pivot outwardly and when the card ejecting mechanism is positioned in the ejecting position then the controlling rod can pivot outwardly.

Abstract: A surface treatment method for substrate includes: spraying liquid is provided, the spraying liquid includes silane coupling agent, leveling agent, isopropyl alcohol, ethanol, acetic acid and water; a substrate having a metallic coating disposed thereon is provided; the spraying liquid is sprayed on the metallic coating, and then spraying liquid is baked to form a transparent protecting layer on the metallic coating; and a painting layer is formed on the protecting layer. The housing formed by the surface treatment method is also provided.

Abstract: A dual SIM card tray and an electrical connector device are disclosed. The electrical connector device comprises a tray and a connector module. The dual SIM card tray has a first receiving groove and a second receiving groove, which are positioned at two opposing sides, for respectively loading a mini-SIM card and a micro-SIM card, and has a first window communicated with the first receiving groove and a second window communicated with the second receiving groove. The first window and the second window are arranged in a lengthwise direction of the tray, so that conductive pads of the two SIM cards are exposed toward the same side. The connector module includes first and second connectors and an outer shell.

Abstract: An electroplating method includes at least the following steps: providing a plastic substrate; forming a preliminary layer containing metal powder and paint on the plastic substrate; laser irradiating the preliminary layer to form an intermediate layer having the metal powder exposed thereon; and electroplating an electroplated layer on the intermediate layer. This electroplating method is simple and can be applied to all kinds of plastic substrate.

Abstract: A method for joining an aluminum part and resin, includes: providing an aluminum part made of aluminum or aluminum alloy; forming a bonding layer on a surface of the aluminum part by coating a liquid film of hydrolyzed silane coupling agent and drying the liquid film; forming an adhesive layer formed of polyurethane adhesive on the bonding layer and curing the adhesive layer; molding a resin part integrally bonded to the adhesive layer.

Abstract: An electrical connector includes an insulative housing (2), a plurality of terminals (3) received in the insulative housing (2) and a shielding shell (4) covering the insulative housing. The insulative housing (2) includes a mating opening (24) extending along a longitudinal direction and a pair of grooves (231) extending with an angle to the mating opening and opening to an exterior. The shielding shell is provided with two shielding shell (41), (42) attached to an outer periphery of the insulative housing (2), which their ends are received and retained in the grooves (231).

Abstract: A card connector adapted for receiving a card which has a notch on a side, comprises an insulating housing defining a card insertion/ejecting direction, a plurality of contacts and an ejector. The ejector comprises a slider movable along the card insertion/ejecting direction, a spring member and a locking member for locking the slider. The slider has a protruding portion for engaging with the notch of the card, the slider is able to move away from the card inserted into the card connector at an original position to allow the protruding portion to leave the notch of the card, and is limited to move away from the card at a final position to lock the protruding portion of the slider in the notch of the card and prevent the card from being pull out at the final position.

Abstract: A card connector (1) includes an insulating housing (2); a number of contacts (3) retained in the insulating housing (2) and a shell (4). The shell (4) covers the insulating housing (2) to define a card receiving space therebetween and defines a card insertion direction. The contacts (3) comprise a number of contacting portions (32) exposed into the card receiving space. A stopper (44) is formed on the shell (4) and protruding into the card receiving space and comprises a stopping portion (440) approximately uprightly exposed into the card receiving space along the card insertion direction to prevent the card from mis-insertion.
