Description

A kind of USB male seat with good earth mode

Technical field

The utility model relates to electronic equipment field of data exchange, relates in particular to a kind of USB male seat with good earth mode.

Background technology

According to USBTYPEC code requirement, need to possess positive and negative plugging function, left and right sides ground connection PIN needs conducting connect and be connected with outer metal housing, and power supply signal PIN also needs conducting to connect, and makes its positive and negative both sides all have conducting function.

As shown in Figure 1, this series products, by the left and right shell fragment 104 on EMC sheet metal, contacts left and right ground connection PIN terminal to prior art, easily be oxidized owing to electroplating Pin terminal, in the middle of long-time use, can cause loose contact, lose conducting grounding function, therefore there is technology hidden danger; Realize the conducting of tow sides corresponding terminal by pcb board circuit, need to customize pcb board 102 and carry out professional SMT welding, operation more complicated.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of USB male seat with good earth mode is provided.

The technical solution of the utility model is as follows:

There is a USB male seat for good earth mode, comprise successively metal shell, reinforcement metal shell fragment, main body plastic cement, front fixing plastic cement, assembling semi-finished product, rear fixing plastic cement; Described assembling semi-finished product comprise conducting sheet mechanism, upper terminal, lower terminal; Ground terminal conducting sheet, signal terminal conducting sheet are contained in described conducting sheet mechanism; Described ground terminal conducting sheet, signal terminal conducting sheet are respectively provided with a pair of upper kink and a pair of lower kink; Described upper kink is used for being fixedly connected with upper terminal one end; Described lower kink is used for being fixedly connected with lower terminal one end; The described upper terminal other end, the lower terminal other end are connected with metal shell inner surface respectively.

Preferably, described two pairs of upper kinks are linearly arranged, and arragement direction is all perpendicular to this USB male seat length direction.

Preferably, in described upper terminal, lower terminal, be respectively equipped with first punching hole corresponding with two kinks, the second punching hole.

Adopt such scheme, the specific vertical folding turn of bilge design of the utility model electricity or signal terminal plane punch structure and conducting sheet, contact after assembling, ensure the conducting of corresponding upper and lower end sub-connection, form loop, direct bonding wire on it, effectively avoid causing to obtain loose contact after the terminal oxidation of elastic piece structure form, conducting lost efficacy hidden danger, meanwhile, also saved pcb board and on welding process.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

As shown in Fig. 2 to Fig. 7 a, 7b, 7c, the utility model provides a kind of USB male seat with good earth mode, comprises successively metal shell 1, reinforcement metal shell fragment 2, main body plastic cement 3, front fixing plastic cement 4, assembling semi-finished product 5, rear fixing plastic cement 6; Described assembling semi-finished product 5 comprise conducting sheet mechanism, upper terminal 54, lower terminal 56; Ground terminal conducting sheet 50, signal terminal conducting sheet 52 are contained in described conducting sheet mechanism; Described ground terminal conducting sheet 50, signal terminal conducting sheet 52 are respectively provided with a pair of upper kink 502,522 and a pair of lower kink 504,524; Described upper kink 502,522 is for being fixedly connected with upper terminal 54 one end; Described lower kink 504,524 is for being fixedly connected with lower terminal 56 one end; Described upper terminal 54 other ends, lower terminal 56 other ends are connected with metal shell 1 inner surface respectively.

Described two pairs of upper kinks 502,522 are linearly arranged, and arragement direction is all perpendicular to this USB male seat length direction.

In described upper terminal 54, lower terminal 56, be respectively equipped with first punching hole 542, second punching hole 562 corresponding with two kinks 502,522,504,524.

Operation principle of the present utility model is as follows:

With reference to Fig. 5 to Fig. 7 a, 7b, 7c, ground terminal conducting sheet 50, signal terminal conducting sheet 52 are fixed on material strip 58, above it, a side has two pairs of upper kinks 502,522, through the first punching hole 542 on upper terminal 54, realizes being connected of conducting sheet 50,52 and upper terminal 54; Below it, a side has two pairs of lower kinks 504,524, through the second punching hole 562 in lower terminal 56, realizes being connected of conducting sheet 50,52 and lower terminal 56.

Refer again to Fig. 5 to Fig. 7 c, in the utility model, material strip 58 is as auxiliary material, the use of pickup during for ease of assembly conducting sheet mechanism, upper terminal 54, lower terminal 56, and after assembling, material strip 58 is given up, and itself is not present in the products assembling.

With reference to Fig. 2 and Fig. 3, after the USB male seat tail end assembling, fix plastic cement and be equipped with holddown groove 60 in both sides Shang Xia 6, outside weldings line (not shown) end is at upper kink 502,522, after lower kink 504,524 welding, line body is drawn through holddown groove 60, thus, sealing wire, ground terminal conducting sheet 50, signal terminal conducting sheet 52, upper terminal 54, lower terminal 56, metal shell 1 are electrically connected, and have reached good earthing effect.

These are only preferred embodiment of the present utility model, be not limited to the utility model, all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
