Description

  The present invention relates to a universal serial bus electrical connector socket.

  Universal Serial Bus (USB) is an electrical signal transmission method for electronic products, and has both characteristics that support hot plug and plug & play (PnP). Its signal transmission speed supports up to 480 Mbps (millions of bits per second), so more electronic products such as computers and communications use the serial bus as the standard transmission interface. This has increased the demand for serial bus electrical connector plugs and sockets.

  Also, according to the trend of carrying electronic products and miniaturization, universal serial bus electrical connectors are also becoming smaller, and are also called small universal serial bus (mini USB) electrical connectors. .

  Conventional mini USB electrical connector sockets include, for example, an insulating housing and a metal shroud, which are disclosed in US Patent Publication No. US 7165589 and US Patent Publication No. 20060035520. The metal casing is covered outside the insulating body, and three notches are provided on one side, and a biasing sheet (flexible cantilever snap lugs) extends from one end of each notch. The three energizing sheets of those metal casings are generally made with a progressive die, the metal casing is placed on the die, and then with a blade having a predetermined shape, some material on the metal casing Is removed by pressing to form three chip openings and a biasing sheet.

  When the mini USB electrical connector plug is inserted from the front of the metal casing into the target insulation body in the metal casing, the biasing sheet elastically hits one side of the mini USB electrical connector plug, A pinching force is applied, whereby the mini USB electrical connector plug is stably inserted on the insulating body without being detached.

  However, the conventional mini USB electrical connector socket has the following problems: the overall size of the mini USB electrical connector socket is small, and the size of the metal casing is relatively small. The distance from the wall surface of the chip is also reduced. When the press molding is performed, the blade cannot smoothly press-mold the blade unless the blade has a relatively thin thickness. Therefore, since the said blade receives comparatively big stress when it press-molds, it is easily damaged and the cost for the maintenance and replacement | exchange of a blade becomes high.

  The inventor proposes the present invention in which the above drawbacks are carefully researched and developed, and the theory can be utilized to improve the above disadvantages in a rational and effective manner.

  The main object of the present invention is to provide a universal serial bus electrical connector socket in which the distance between the biasing sheets is relatively large, and the service life of the blade pressing the biasing sheet is improved. To do.

  In order to achieve the above object, the present invention is a universal serial bus electrical connector socket, an insulating body having a plurality of terminal tanks, a plurality of conductive terminals installed on the terminal tank of the insulating body, Covering outside of the insulating main body, provided with a chip opening, at least one first biasing sheet and at least one second biasing sheet, the chip opening being installed on one side of the metal casing, The urging sheet and the second urging sheet contain a metal casing that extends from the chip end at an interval.

  According to the present invention, the following advantages are obtained, and the first urging sheet and the second urging sheet are formed in the same notch and are between the first urging sheet and the second urging sheet. Therefore, when the first urging sheet and the second urging sheet are formed, the thickness of the blade to be pressed is relatively thick, and the stress applied to the blade is relatively And the service life of the blade is improved.

  Hereinafter, the features and technical contents of the present invention will be described in detail with reference to the drawings. However, the drawings are for reference and explanation, and the present invention is not limited thereby. .

  1, 2, and 3, the universal serial bus electrical connector socket according to the present invention includes an insulating body 10, a plurality of conductive terminals 20, and a metal casing 30.

  The insulating body 10 is made of an insulating material (for example, plastic) and is integrally molded by injection molding. The insulating body 10 has a plurality of horizontally arranged terminal tanks 11 penetrating both front and rear sides of the insulating body 10. .

  The conductive terminals 20 are integrally formed of a metal material having a high conductivity coefficient, and are inserted into the terminal tank 11 of the insulating main body 10 in order, and the ends of the conductive terminals 20 are outside the insulating main body 10. It is soldered to a circuit board (not shown in the figure) and electrically connected to the circuit board.

  The metal casing 30 is a metal plate material, which is curved and molded by a method such as pressing, and has a substantially rectangular frame structure. The metal casing 30 has a hollow casing structure, and openings 31 are formed at both front and rear ends. Then, the insulating body 10 is inserted into the metal casing 30 from the rear opening 31, so that the metal casing 30 covers the outside of the insulating body 10. A serial bus electrical connector plug (not shown) is inserted from the opening 31 at the tip of the metal casing 30 and is inserted on the insulating body 10.

  As shown in FIG. 4, the metal casing 30 includes a notch 32, a first urging sheet 33, and two second urging sheets 34, and the notch 32 is installed on the upper surface of the metal casing 30. In addition, the first biasing sheet 33 extends obliquely downward from one end of the notch 32 in the metal casing 30, and the second biasing sheet 34 further extends from the notch 32. In the metal casing 30, the metal casing 30 extends obliquely downward, that is, the direction in which the second urging sheet 34 extends is opposite to the first urging sheet 33. In another embodiment, the extending direction of the first urging sheet 33 and the second urging sheet 34 may be designed in the same manner.

  The second urging sheets 34 are located on both sides of the first urging sheet 33 with a space therebetween, and the width is smaller than the width of the first urging sheet 33.

When serial bus electrical connector plugs (not shown) are inserted from the opening 31 at the tip of the metal casing 30 and inserted into the insulating body 10 for electrical connection, the biasing sheets 33, 34 elastically contacts one side of the serial bus electrical connector plug and applies a pinching force, so that the serial bus electrical connector plug can be stably insulated without being detached. Inserted on the main body 10, the stability of the electrical connection between the serial bus electrical connector plug and the serial bus electrical connector socket is ensured.

  According to the present invention, the following effects are obtained, and the first urging sheet 33 and the second urging sheet 34 are formed in the same notch 32, and the first urging sheet 33 and the second urging sheet 34 are also formed. Since there is a relatively large gap between the force sheets 34, when pressing the force sheets 33, 34, the thickness of the press blade may be relatively thick. Since the stress applied to the blade is also relatively small, the service life of the blade is improved. In particular, when producing a biasing sheet (not shown in the figure) of a small universal serial bus (mini USB) electrical connector, the above effect becomes more prominent.

  Therefore, the present invention is more progressive and more practical, and filed a utility model registration request in accordance with the law.

  The above is only a better embodiment of the present invention, and the present invention is not limited thereby, and the equivalents made based on the scope of claims for utility model registration related to the present invention and the contents of the description. All changes and modifications are included in the scope of the utility model registration request of the present invention.
