Patent documentation 1: No. 3141351 communique of Japanese Utility Model registration

There is following problem in Minimized USB connector shown in the prior art document:

(1) because contact site (terminal needle inserting) exposes in peristome, so the foreign matter entered from peristome sometimes is stained.

(2) due to the plane with respect to case housing, the peristome of Minimized USB connector depression is larger, so can see the inboard of peristome, associative perception, the feeling of high class between infringement and component design often.

Summary of the invention

The present invention makes in view of the above problems, and its purpose is the electric connector that provides following:

(1) prevent the intrusion of foreign matter.

(2) realize one sense, the feeling of high class of component design and electric connector.

(3) guarantee and Minimized USB connector between interchangeability.

Electric connector with shutter of the present invention and Minimized USB connector have interchangeability, this electric connector with shutter is characterised in that, in the framework 10 that is provided with terminal terminal 20, shield member 30 is installed, be provided with the shutter 40 engaged with spring 50 in the fitting portion 60 that has inserted the micro USB plug, shutter 40 along with the insertion of micro USB plug in the interior movement of fitting portion 60, when extracting the micro USB plug, shutter 40 is returned to the face side of fitting portion 60 by spring 50.

The invention effect

According to the present invention, realized following electric connector:

(1) can prevent the intrusion of foreign matter.

(2) can realize one sense, the feeling of high class of component design and electric connector.

(3) can guarantee and Minimized USB connector between interchangeability.

(4) poor by making shutter depression produce slightly ladder, by the poor easy reception micro USB plug of this ladder, and become the sign of insertion section, can bring the sense of security to the user.

Embodiment

According to Fig. 1 to Figure 12, execution mode is described.

As shown in Figure 9, electric connector 1 of the present invention consists of framework 10, terminal terminal 20, shield member 30, shutter 40 and spring 50.

Terminal terminal 20 is by forming electric conductor punch process such as brass.

Be formed with the contact site 21 be electrically connected to the contact site of the opposing party's micro USB plug (not shown) and be soldered to the portion of terminal 22 on circuit substrate on terminal terminal 20, the surface of terminal terminal 20 is subjected to gold-plated processing.

Framework 10 is polyamide etc. to be carried out to the insulator of processing and forming.

In the present embodiment, framework 10 and terminal terminal 20 are embedded into moulding.

Have to arrange in framework 10 and exposed the connecting portion 11 of five contact sites 21 and the protuberance 12 engaged with spring 50.

And contact site 21 is set with the interval of 0.65mm, in order to there is interchangeability with Minimized USB connector.

Rear side in framework 10 is arranged with portion of terminal 22.

Shield member 30 forms by the electric conductors such as stainless steel are carried out to punch process, and the surface of shield member 30 is subjected to zinc-plated processing.

On shield member 30, there is slit 31, fastening part 32 and be soldered to the portion of terminal 33 on circuit substrate.

Shield member 30 is installed on framework 10, is formed with the fitting portion 60 for inserting the micro USB plug.

And fitting portion 60 has interchangeability with Minimized USB connector.

Shutter 40 is polyamide etc. to be carried out to the insulator of processing and forming.

The recess 42 that there is retainer 41 and engage with spring 50 on shutter 40.

From the viewpoint of component design, consider, shutter 40 can be also colour.In this case, at least face side is painted gets final product, and also can use painted moulding material.

Spring 50 is coil springs that stainless steel etc. is processed.

One end of spring 50 is sticked in the protuberance 12 of framework 10, and the other end is sticked in the recess 42 of shutter 40.

Then, assemble method is described

Shutter 40 is inserted from the rear side of shield member 30.

Retainer 41 engages with slit 31.

When inserting the micro USB plug, retainer 41 is configured to the guide portion of sliding along slit 31, and, when having extracted the micro USB plug, shutter 40 is configured to can not come off in face side.

2 springs 50 are arranged on the protuberance 12 at 2 places of framework 10.

Spring 50 is engaged with recess 42, framework 10 is installed on to shield member 30.

Fastening part 32 and portion of terminal 33 are bent to fixed mask parts 30 and framework 10 along framework 10.

According to the above-mentioned electric connector of the present invention be assembled into, when the micro USB plug does not insert, as shown in figure 10, shutter 40 is the state in closing by exerting pressure of spring 50, and still, along with the insertion of micro USB plug, shutter 40 moves in fitting portion 60, as shown in figure 11, spring 50 is compressed.

In addition, in the present embodiment, under the state that does not insert the micro USB plug, shutter 40 does not fully cover fitting portion 60, but is set with the state of the 61 depression 1.1mm from the face side end.

Like this, poor by making shutter 40 depressions produce slightly ladder, by the poor effect with easy reception micro USB plug of this ladder, and the poor formation of this ladder insertion section sign, therefore there is the effect of the user being brought to the sense of security.

In addition, because the amount of movement of shutter 40 has reduced the amount of depression, thus can shorten the depth towards rear side from face side end 61, thereby can realize miniaturization.
