Abstract

The utility model provides an easy-insert USB connector. The centre of a metal housing of an A type connector USB connecting plug is provided with a thin printed circuit board (PCB for short), the upper end and the lower end of the printed circuit board are provided with four pieces of printed circuits, and the printed circuit board divides the inner region of the metal housing into equal lower and down accommodating spaces; the USB plug can positively or reversely be inserted into an USB socket of the normal computer host, thereby, the electricity connection has convenience and practicability.

Description

The USB connector that is easy to peg graft

Technical field

The utility model refers to especially that relevant for a kind of USB connector that is easy to peg graft a kind of USB plug of A type connector can be plugged in the USB socket of general main frame forward or backwards.

Background technology

General USB (Universal Serial Bus, abbreviation USB) connector is that present main frame connects the essential product of computer interface equipment, and wherein computer interface equipment system includes computer keyboard, mouse, tabulating machine, digital camera, scanner, modulator-demodulator, battery charger, PDA, mobile phone, the carry-on dish of USB extraction-type and external hard drive ... in device; Consult shown in Figure 1, general main frame front and back ends is respectively equipped with at least one USB socket (Female Connector) 100, these USB socket 100 outsides are the metal shell 101 of a rectangle, shell 101 inner and upper have the copper cash plastic plate 102 of a rectangle, the jack 103 that the below, inside has a rectangle, the copper cash 1021 of four conductions of tool on this copper cash plastic plate 102.

Consult Fig. 2 and shown in Figure 3, the USB plug (Male Connector) 200 of general A type connector is can be plugged in the USB socket 100 of main frame, the outside cording of this USB plug 200 has the metal shell 201 of a rectangle, shell 201 inner belows have a copper cash plastic plate 202, the copper cash 2021 of four conductions of tool on the copper cash plastic plate 202, shell 201 inner and upper have the tank 203 of a rectangle; Cooperate shown in Figure 4, when the USB plug 200 of A type connector is plugged in the USB socket 100 of main frame, the copper cash plastic plate 202 of USB plug 200 inserts in the jack 103 of

USB socket

100, and 203 of the tanks of USB plug 200 can insert for the copper cash plastic plate 102 of USB socket 100.

Because the USB plug 200 of existing A type connector has only in the insertion USB socket 100 of single direction, when USB plug 200 reverse (turning upside down), just can't insert in the USB socket 100, inconvenience in the extreme when operation, and the easier connector that causes of reverse grafting is impaired, thereby have much room for improvement.

In view of the above problems, a kind of novel USB connector of being convenient to peg graft is proposed now, to overcome the existing product shortcoming and to promote effect.

The utility model content

Main purpose of the present utility model is to provide a kind of USB connector that is easy to peg graft, tool one metal shell on the USB plug of A type connector, enclosure central authorities tool one printed circuit board (PCB), enclosure is divided into, following two accommodation spaces, on this printed circuit board (PCB), the lower end all is printed with at least one printed circuit, because above-mentioned two accommodation spaces all can insert for the copper cash plastic plate of general main frame USB socket inside, realizing that USB plug can peg graft with the USB socket of general main frame forward or backwards, with overcome improper grafting the impaired phenomenon of the connector that caused.

Embodiment

See also Fig. 5 A, Fig. 5 B and shown in Figure 6, the USB plug (MaleConnector) 10,10 ' of the utility model A type connector goes up the metal shell 11 of tool one rectangle, shell 11 central interior have the printed circuit board (PCB) 12 (its thickness is about 0.024inch) of an electric installation, this printed circuit board (PCB) (PCB) 12 also can be close pulling-on piece (Mylar, or title polyester film) or copper cash plate or epoxy resin board (Epoxy) or glass mat (Fiber Glass) ... etc. structure; And printed circuit board (PCB) 12 is divided into upper and lower two

accommodation spaces

13,14 with metal shell 11 inner area; Cooperate shown in Figure 7ly, the printed circuit 121 of printed circuit board (PCB) 12 upper ends system printing (Layout) at least one tool electric conductivity cooperates shown in Figure 8ly, and printed circuit board (PCB) 12 lower ends also are printed with the printed circuit 122 of at least one tool electric conductivity.

Because on the printed circuit board (PCB) 12 of metal shell 11, following two

accommodation spaces

13,14 the thickness with the copper cash plastic plate 102 of Fig. 1 main frame USB socket 100 is identical respectively, when USB plug 10 of the present utility model, when 10 ' forward ground inserts in the main frame USB socket 100, as Fig. 9, USB plug 10, the accommodation space 13 of 10 ' upper end is to insert for the copper cash plastic plate 102 of USB socket 100, and USB plug 10,121 printed circuits 1021 with USB socket 100 copper cash plastic plates 102 belows of the printed circuit of 10 ' the central printed circuit board (PCB), 12 tops contact with the conducting electric current.When the

USB plug

10,10 ' of this creation is oppositely inserted in the main frame USB socket 100 (turning upside down), as Figure 10, the accommodation space 14 of USB plug 10, the 10 ' other end can insert for the copper cash plastic plate 102 of USB socket 100, and the printed circuit 122 of

USB plug

10,10 ' central printed circuit board (PCB) 12 other ends then contacts with the conducting electric current with the copper cash 1021 of USB socket 100 copper cash plastic plates 102 belows.

In sum, the USB connector that this creation is easy to peg graft, mainly the PCB design with general A type connector or the carry-on dish of USB extraction-type becomes thin and is placed in the shell central part, the upper and lower end of this printed circuit board (PCB) all is provided with the printed circuit of conduction, make the printed circuit board (PCB) upper and lower end of USB connector all be provided with impartial accommodation space, these upper and lower two accommodation spaces all can be planted for the copper cash plastic plate of USB socket, thereby USB plug can be plugged in the USB socket of general main frame forward or backwards, to realize its effect.
