Description

Plug connector
Technical field
The present invention relates to plug connector, relate in particular to the plug connector on the mobile electronic devices such as being used in mobile phone, PDA (carrying information terminal), digital camera.
Background technology
In recent years, the market of mobile electronic devices such as mobile phone, PDA (carrying information terminal), digital camera enlarges rapidly.
When using these mobile electronic devices to carry out the occasion of data communication or charging, the cable of general using band plug connector (for example with reference to patent documentation 1: the spy opens 2005-85469 communique (Figure 10), patent documentation 2: the spy opens the 2001-185282 communique).
These plug connectors will have the housing of the plug section that is electrically connected with the other side's connector is connected the cable of heart line with solder on the contact pin in plug section the outside of coupling part; the fore-end that exposes above-mentioned plug section; and the holding part of other parts with two parts that are divided into loam cake and lower cover covered, and protection does not produce distortion etc. on the coupling part of contact pin and cable.
As the installation method of this loam cake and lower cover, for example from patent documentation 1, patent documentation 2 as can be known, the known method that is screwed loam cake and lower cover mutually etc.
In addition, the plug connector of known following formation also, promptly plug connector 101 as shown in Figures 3 and 4 is such, hook 103 is set on loam cake 102a, and the wheel bore 104 that is pressed into or cooperates hook 103 is set on lower cover 102b, between loam cake 102a and lower cover 102b, sandwich housing 105, and pass through the cooperation of hook 103 and wheel bore 104, loam cake 102a fastened to each other and lower cover 102b.
Yet the intensive contact pin that is equipped with on the plug section base portion is so as the plug connector that patent documentation 1, patent documentation 2 are put down in writing, in the structure that is screwed loam cake and lower cover, nearby can not be provided with screw mechanism at the connector base portion.Therefore, deflection is provided with screw mechanism with the rearward end side of the plug connector that the connector base portion separates, thus there is fixing instability, and if the problem points that the intersection twist and warping nearby of connector base portion are then opened because of carelessness.
On the other hand, as Fig. 4 and shown in Figure 5, in structure with the hook 103 that is pressed into mutually or cooperates and wheel bore 104 fixed cover 102a and lower cover 102b, adopt the method that sandwiches housing 105 with loam cake 102a and lower cover 102b, so between loam cake 102a and lower cover 102b, form the gap, have the problem that shakes easily.And, the fixed part of hook 103 and wheel bore 104 only plug section nearby about two places carry out, open relatively or the shortcoming of the undercapacity of twist and warping power etc. so also exist.
Summary of the invention
So, produce greatly in order to make the intensity of opening relatively or twisting and warping, and assembly operation is easy to structure technical task to be solved, the present invention is a purpose to solve this problem.
The present invention proposes in order to achieve the above object, and scheme 1 described invention provides a kind of plug connector, possesses: the housing with the plug section that is electrically connected with the other side's connector; And the holding part that sets of a part of surrounding the periphery at least of this housing, above-mentioned holding part is divided into loam cake and two lids of lower cover, two places up and down of the left and right side near the above-mentioned plug section base portion of above-mentioned housing, the upside hook portion of pair of right and left and the downside hook portion of pair of right and left are set respectively, and on the medial surface of the left and right sides of above-mentioned loam cake, corresponding with the upside hook portion of above-mentioned pair of right and left and be provided with respectively can be chimeric with this upside hook portion loam cake side hook portion, and on the medial surface of the left and right sides of above-mentioned lower cover, corresponding with the downside hook portion of above-mentioned pair of right and left and be provided with respectively can be chimeric with the downside hook portion of this pair of right and left lower cover side hook portion, make each hook portion of above-mentioned mutual correspondence chimeric mutually, thereby above-mentioned loam cake and above-mentioned lower cover are installed on the above-mentioned housing.
According to this structure, because the hook portion of the bottom hook portion of the pair of right and left of the chimeric and case side of the hook portion of the top hook portion of the pair of right and left by case side and the pair of right and left of loam cake side and the pair of right and left of lower cover side is chimeric, make loam cake and lower cover respectively about housing two places chimeric and fixing, so can with eliminate between loam cake and the housing rock and lower cover and housing between the state that rocks, Jiang Gegai is fixed on the housing.
Scheme 2 described inventions provide a kind of plug connector according to scheme 1, are wholely set the pedestal portion of the base portion that keeps above-mentioned plug section on above-mentioned housing, form the above-mentioned hook portion of above-mentioned case side on the lateral surface of the left and right sides of this pedestal portion respectively.
According to this structure, owing on the left and right sides face of the pedestal portion of the base portion that keeps plug section, form the hook portion of case side respectively, at the base portion of plug section nearby fixed cover and lower cover respectively, thus the base portion of plug section on nearby housing and the bond strength of loam cake and lower cover increase.
Scheme 3 described inventions provide a kind of plug connector according to scheme 1 or scheme 2, be located at above-mentioned loam cake and above-mentioned above-mentioned hook portion that covers down and the above-mentioned hook portion that is located at above-mentioned case side, the impingement area that will when above-mentioned loam cake and the above-mentioned relatively housing of above-mentioned lower cover compress, run foul of each other, inclined plane with the left and right side of making a concession this loam cake that compresses and from lower cover to foreign side forms, and is formed on when chimeric chimeric the opposing party's interface mutually with the plane.
According to this structure, if loam cake or lower cover are compressed to case side, then according to the shape on inclined plane, the loam cake of a compacted side or the hook portion of lower cover are made a concession to foreign side, allow being pressed into of this lid by this yielding.And, if lid is pressed into the position of regulation, then covers the side hook portion and recover elasticity, in the plane of the hook portion of lid side and butt joint and chimeric conscientiously mutually on the plane of the hook portion of case side.
The present invention has following effect.
Scheme 1 described invention can with eliminate between loam cake and the housing rock and lower cover and housing between the state that rocks, loam cake and lower cover are fixed on the housing, so can improve the quality of product.
Scheme 2 described inventions are nearby distinguished between stationary housing and loam cake and the lower cover at the base portion of plug section, thus not only have the effect of the invention of scheme 1, and especially nearby can increase the bond strength of housing and plug section at the base portion of plug section.
Scheme 3 described inventions are if compress loam cake and lower cover to case side, the hook portion of then compacted loam cake and lower cover side is outwards side's yielding automatically respectively, being pressed into of this loam cake and lower cover is allowed to, and if be pressed into the position of regulation, then each hook portion of loam cake and lower cover side is recovered elasticity, the mutually butt joint and chimeric conscientiously of the plane of the hook portion of the plane of the hook portion of case side and loam cake and lower cover side, so not only have the effect of scheme 1 or scheme 2 described inventions, and can further improve assembly operation.
