Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.

To disclose a kind of micro USB connector below in embodiment of the present utility model, it is applicable to the charging of portable electron devices such as mobile communications device and/or transfer of data etc.In the present embodiment, but those of ordinary skill knows that obviously this micro USB connector can be applied to any needs carries out in the USB connector or structure of other models that USB connects, particularly in the communications field.The description of following specific embodiment just is in the purpose of example thus, and can not think the restriction to protection range of the present utility model.

Describe in detail according to an embodiment of the present utility model with reference to Fig. 2,3 below.Wherein, Fig. 2 is the schematic perspective view according to the micro USB connector of an embodiment of the present utility model.Fig. 3 is the three-dimensional exploded view according to the micro USB connector of an embodiment of the present utility model.

As shown in Figure 2, according to an embodiment of the present utility model, this micro USB connector comprises: first housing 1; Second housing 2; Insulating body 5; Be arranged at least one conducting terminal 4 on the described insulating body 5; Described first housing is provided with metal-back portion 3, and this metal-back portion 3 coats the insulating body 5 that is provided with described conducting terminal 4, and described first housing 1 is connected by buckle with described second housing 2, shown in Fig. 2 middle interconnecting piece position.

Shown in detailed among Fig. 3, the left side of first housing 1 is formed with metal-back portion 3, described metal-back portion need meet the requirement of the standard of MINI-USB attachment unit interface, and for influencing the elaboration of main points of the present utility model for purpose of brevity and not, its detailed structure is not described in further detail herein thus.Stretching out from the bottom of metal-back portion 3 is provided with base section 101, and the cross side of this base section 101 is formed with lateral side part 102 simultaneously.Stretch out on the right side of first housing 1 (second end), from described base section 101 and to be formed with lower wire standing part 105 (being positioned at second end of second housing 2).The metal-back portion 3 of described first housing 1 is provided with draw-in groove 104, be used for second housing 2 on the grab 201 (will be elaborated in the back) that is provided with carry out buckle and be connected, described draw-in groove 104 described grabs 201 are arranged on the left end (first end) of described second housing 2.Described grab 201 stretches out from the cross side of the left end (first end) of described second housing 2 respectively.

On insulating body shown in Figure 35, be formed with terminal holding tank 501 respectively, and on the surface of the left end of insulating body, be formed with inclined-plane 502, be used for conveniently slipping into described metal-back portion with the matching parts insertion of this micro USB connector and being electrically connected with the terminal 4 that is arranged on described terminal holding tank 501.The number of described terminal 4 can change according to the requirement of the electronic product of concrete application is different.This insulating body 5 is provided with terminal position portion 503 simultaneously, and terminal 4 can be fixed on by the hole (not shown) in the terminal position portion 503 in the described terminal holding tank 501.

Two widthwise side portions 206 that second housing 2 has top section 202, extend downward vertically from described top section, from described widthwise side portions 206 outward extending two grabs 201, for grab 201 being stretched into from the inboard of described first housing 1 and engaging with described draw-in groove 104, the grab that is formed on described widthwise side portions 206 is a little to bias internal, and on the front end of described grab 201, be formed with the projection that projects upwards, be used for carrying out firm clamping with described draw-in groove 104.Thus, first housing 1 and second housing 2 can form stable fit structure, even run into than big pulling force or under situation about frequently plugging in accident, this fit structure can guarantee that also first housing and second housing can not come off, thereby has improved the useful life of quality of connection and this micro USB connector.

Further, those of ordinary skill can change above-mentioned structure, for example the top surface from the right side of described metal shell 4 can be formed with outward extending grab, being described grab 201 stretches out from the top side of described metal shell 4, and on the top surface 202 of second housing 2, be formed with draw-in groove, described grab offset downward a little and can be under the top section 202 of described second housing by and carry out clamping with draw-in groove that described top section 202 forms, can obtain like this and above-mentioned similar technique effect.

Further, in order to strengthen above-mentioned clamping effect, on two widthwise side portions 206 of described second housing 2, be formed with projection 203 respectively, and accordingly on two widthwise side portions 102 on the right side of described first housing 1 (second end) with these projection 203 corresponding open slots 103 that are provided with, thereby when assembling, described protruding 203 with described open slot 103 snap engagement, thereby further strengthened above-mentioned tight engagement effect.

But as mentioned above, those of ordinary skill can change the setting of above-mentioned open slot 103 and projection 203.For example, on described widthwise side portions 102, be formed with projection 103 ', and on widthwise side portions 206, be formed with described open slot 203 '.Thereby described protruding 103 ' and described open slot 203 ' can carry out clamping in inside.

In addition, the right side of described top section 202 stretches out and is provided with upper conductor standing part 205, and described upper conductor standing part 205 cooperates with described lower wire standing part 105, is used to hold the lead of access.In according to an embodiment of the present utility model, this upper conductor standing part 205 after the combination and the cross section of described lower wire standing part 105 can form and be suitable for the shape that engages with lead, for example circle, ellipse etc.

Fig. 4 a, 4b have shown that the master according to the micro USB connector of the present utility model of the micro USB connector of an embodiment of the present utility model looks exploded view and side-looking exploded view.Fig. 5 a, 5b have shown front view and the end view of micro USB connector of the present utility model after assembling according to the micro USB connector of an embodiment of the present utility model.In Fig. 4-5, the insulating body 4 that at first will be provided with terminal 4 is inserted in described first housing 1, as shown in Fig. 4 a, 4b.First housing 1 that will assemble then carries out buckle with described second housing 2 and is connected, and wherein said grab 201 is snapped into described draw-in groove 104, and described protruding 203 are snapped in the described open slot 103.Fig. 5 a, 5b have shown this micro USB connector after assembling, and wherein lead is bonded between the described upper conductor standing part 205 and described lower wire standing part 105 after the assembling.Then, the micro USB connector that this is assembled is put into suitable mold and is carried out injection mo(u)lding and form the product with suitable configuration.Because good snap engagement between this first housing 1 and second housing 2, in the process of injection mo(u)lding, colloid is difficult to enter by the slit of this fit structure the inner space of described micro USB connector, thereby the connector recurring structure that can not cause having assembled is out of shape or dislocation, thereby has guaranteed the rate of finished products of product.

Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that under the situation that does not break away from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claims and equivalent thereof.
