Abstract

The utility model discloses an L-shape USB plug, which comprises an L-shape metal substrate, a plastic base and four metallic cards. The L-shaped metal substrate comprises a soleplate and a lateral plate to form the case of the plug; the plastic base is fixedly arranged on the running surface of the inner side of the soleplate; four fixed grooves parallel with the lateral plate are arranged on the plastic base; the metallic cards are fixed in the fixed grooves. The plug reduces two lateral panels based on the plug with rectangular four-face frame-type case of prior USB plug, saves materials and at the same time reduces the volume of the plug, thus realizing the miniaturization of the product.

Description

L type USB plug

Technical field

The utility model relates to a kind of computer peripheral device, relates to a kind of USB plug, relates in particular to a kind of L type USB plug.

Background technology

USB plug of the prior art is the USB plug of four sides bound edge, its diagonal-size is about 12.4mm, and is wide about 12mm, and thick is about 4.6mm, and actual in application the position of its contact have only half, and in some product (as the pen type USB flash disk etc.) is used, can't realize littler size.

Summary of the invention

The purpose of this utility model is to improve the deficiency that the USB plug size can't further reduce again in the prior art, provide a kind of on the basis of prior USB plug minification to greatest extent, reduce material, and can be compatible with all USB seat energy, make its fitted position in product is used do forr a short time, thereby realize pocketization of product, microminiaturized L type USB plug.

The purpose of this utility model is achieved in that

The L type USB plug that the utility model provides comprises a L type metal substrate, a plastic cement pedestal and four metal needles, L type metal substrate comprises a base plate and a side plate, constitute the shell of plug, on the interior plate face of described base plate, set firmly described plastic cement pedestal, be provided with four holddown grooves parallel with described side plate on described plastic cement pedestal, described metal needle is fixed in the described holddown groove.

In use, four metal needles in this L type USB plug contact with contact chip on the general USB seat, thereby realize the circuit result that communicates; A side of stretching out in the L type metal substrate in this plug can be positioned a side of the contact chip that contacts with four metal needles of this plug in the Universal USB seat on the same plane.Thereby four metal needles of this plug are contacted better with four contact chips on the Universal USB seat, guaranteed that this plug can not have any slip in the Universal USB seat.

For convenience with the metal needle on this plug with use in the welding ends welding such as the circuit of USB flash disk, metal needle is fixed in the groove in the plastic cement pedestal, the end of metal needle stretches out, and constitutes the welding ends that is connected with electronic circuit.Four strip metal pin welding endss of this L type USB plug are connected with electrical backplane (pcb board), and mode such as bonding again or other riveted joint of pcb board is fixed itself and plastic cement pedestal.

Be connected firmly between described metal substrate and the plastic cement pedestal in order to make, one side of metal substrate and plastic cement substrate has been made concavo-convex mosaic texture, and have the hole in the bottom of metal substrate, the plastic cement pedestal is provided with the protrusion piece, embed in the Metal Substrate film perforation fixing, thereby realized better the fixedly connected mode of L type metal substrate with the plastic cement pedestal, the position of protruding on the plastic cement pedestal simultaneously also is the positioning end with the plastic shell of electronic product such as USB flash disk etc.

The L type USB plug that the utility model provides is by removing two side panels on the frame type shell plug basis, four sides of existing USB plug rectangle, it saves material, simultaneously, can be so that the volume-diminished of plug, thus pocketization of realization product, microminiaturization.Simultaneously, four metal needles of four electrodes on the joint pass through in the holddown groove on the plastic cement pedestal fixing, and need not cover the copper layer, thereby have realized mass production greatly.Its reason is, metal needle is not subjected to appoint the restriction of shape of product, can make standardized accessory, realizes supporting with any USB product that may miniaturization covering the influence that the copper layer then will be subjected to product structure, and different product have to be done a pcb board.

Embodiment

As shown in Figure 1, 2, 3, the L type USB plug that the utility model provides is made of L type stainless steel-like metal substrate 1, plastic cement pedestal 2 and four metal needles 3, L type metal substrate 1 comprises a base plate 12 and a side plate 11, constitute the shell of plug, on the interior plate face of base plate 12, set firmly plastic cement pedestal 2, be provided with four holddown grooves parallel with side plate 4 on plastic cement pedestal 2, metal needle 3 is fixed in the holddown groove 4.

Four metal needles 3 of this L type USB plug are fixed on the plastic cement pedestal 2 by the holddown groove on the plastic cement pedestal 24, plastic cement pedestal 2 is installed in the L type metal substrate 1 then, its metal substrate 1 is provided with and 6 fixations of plastic cement pedestal 2 corresponding groove (seeing Fig. 4,5), makes it in use be unlikely slippage.Shown in Fig. 3,7,8, the welding ends 5 that L type USB plug can be by metal needle 3 with use in PCB (as USB flash disk etc.) on welding ends link to each other and can use.Shown in Fig. 7,8.

In use, as shown in Figure 6, four metal needles 3 in the L type USB plug contact with the contact chip 710 that contacts on the extremity piece 71 on the general USB seat 7, thereby realize the connection of circuit; A side 11 of stretching out in the L type metal substrate in this L type USB plug is positioned a side of the contact extremity piece 71 that contacts with four metal needles of this product in the Universal USB seat on the same plane, thereby four metal needles 3 of this product are contacted better with four contact chips 710 on the Universal USB seat, guaranteed that this product can arbitrary slip in the Universal USB seat.

This product can be by metal needle welding ends 5 with use in PCB (as USB flash disk etc.) on welding ends link to each other and can use.
