Description

Electric connector

[technical field]

The utility model is about a kind of electric connector, particularly is used on mobile phone, PDA or other information products about a kind of, as the design improved of seizing shell fragment on both sides by the arms of electric connector of output, input interface transmission signal function.

[background technology]

In recent years because the information prosperity, the transmission of data applies on all types of different communication products also more and more universal, and the universalness of these communication products and convenience have also changed the behavior pattern that people transmit data, from early stage magnetic sheet access, to Internet data transmission now, be developed to further wireless telecommunications now even, communication product now also more and more strides forward with high efficiency unification designer trends towards multi-functional, and facing to these high efficiency demands, also inevitable change to some extent on its external form and the structural design along with cooperating these functions, the just necessary change of the function of some member, could match with the design of product, and for the Use Limitation of strengthening and increase these products so that it brings into play its best function, it has been the trend of present dealer's exploitation that the improvement of product-structurant is made its mode that prolongs the pot life.

In the structure of communication product as mobile phone, PDA, digital still camera etc., the signal transmission socket is the important Connection Element that communication product is connected with external module, and using on these elements, the number of times number of the plug between the socket and plug, to have influence on the useful life of product, become an important indicator of product stability and useful life longevity.

The design of existing electric connector is a plug and the combination of docking of female type, in order to increase both bond strengths when docking, the covering of socket connector all designed on the shell and seized shell fragment on both sides by the arms as the clamping piece of seizing plug on both sides by the arms, the existing electric connector that is disclosed is seized the shell fragment designing technique on both sides by the arms, it is size according to connector, covering the shell fragment of seizing on both sides by the arms that varying number is set on the both ends of the surface up and down of shell, wherein, the design of seizing shell fragment on both sides by the arms of lower surface is to match with the button hole of pin connector bottom, its certain standard specification is arranged, the shell fragment of seizing on both sides by the arms that covers the shell upper surface then is to utilize the intensity of the shell fragment arm of force to seize pin connector on both sides by the arms, has better firm effect when plug is inserted.Difference in response to the termination actinal surface, small-sized socket connector is provided with two in the upper surface of covering shell and seizes shell fragment on both sides by the arms, relatively large socket connector then has three and seizes shell fragment on both sides by the arms, adopt the staggered mode of direction to set up, the existing mode that adopts is the design of continuity miniature connector, both sides adopt the mode of Inside out to be provided with than the shell fragment (secondary shell fragment) of seizing on both sides by the arms of small pieces, be provided with inwardly by termination actinal surface direction, middle large stretch of shell fragment (main shell fragment) of seizing on both sides by the arms is adopted the mode of Outside in and is provided with, and towards the termination actinal surface (as shown in Figure 1) is set by the inside of covering shell.Seize power on both sides by the arms when the arm of force intensity of seizing shell fragment on both sides by the arms then can directly influence fixedly, and further have influence on the number of times of joint plug.Cause is prevailing of small-sized digital communications product now, the number of times of grafting electric connector is quite frequent, the plug number of times of electric connector in the past requires to reach 5000 times standard, but complies with frequency of utilization now, and the plug number of times that reaches 10000 times has become the new standard that requires.Existing mode of seizing shell fragment on both sides by the arms because of design, the acting force arm that forms main shell fragment is all too short, has weakened the power of seizing on both sides by the arms of whole electric connector for socket, more easily causes plug built on the sand when being connected with plug, and the problem that is easy to get loose will have influence on the laser propagation effect in when use.In addition, because of in the design of seizing shell fragment on both sides by the arms, the design of shell fragment is at present all adopted to intersect and is furnished, and promptly main shell fragment is formula in interleaved relation with each other with the bearing of trend of its secondary shell fragment of assisting a ruler in governing a country mutually, reduces the ductile space of the main shell fragment arm of force, so cause reducing product usefulness, therefore if its shell fragment is improved, connector shell is consolidated more in same position, increase the stability of itself and outside connector, make the damage of product rate reduce, and facilitate product usefulness to improve.

[utility model content]

For improving the disappearance of existing electric connector, the purpose of this utility model is to provide a kind of electric connector, can increase the steadiness that is connected between connector body and the plug, reduce spoilage, and can increase contact engaging and separating force between socket and plug, increasing the plug access times, and then improve product quality.

In order to achieve the above object, the utility model provides a kind of electric connector, and this electric connector comprises: one covers shell, a glue core and a terminal group, it is characterized in that:

This covers the shell fragment of seizing on both sides by the arms that the shell top end face is provided with one group of fixedly connected plug, this each seize shell fragment on both sides by the arms tail end form a sweeping portion that supports, it pair that comprises that master in the middle of being positioned at seizes shell fragment on both sides by the arms and is positioned at both sides is seized shell fragment on both sides by the arms, and this master seizes shell fragment on both sides by the arms and covers middle part, outer casing top surface rear end by this and cover the direction extension of shell interface to this.

Described electric connector is characterized in that: it is identical with secondary bearing of trend of seizing shell fragment on both sides by the arms that this master seizes shell fragment on both sides by the arms.

In sum, electric connector of the present utility model mainly is to cover shell, a glue core and a terminal group by one to be constituted; It is to cover master on the shell and seize that shell fragment and secondary bearing of trend of seizing shell fragment on both sides by the arms are unified to be same direction on both sides by the arms being positioned at electric connector, all the mode with Inside out is provided with, so can increase the steadiness between connector body and the plug, reduce spoilage, and then the raising product quality, and by the arm of force that the makes main shell fragment length that is increased, and then strengthen the plug power that it can bear, to promote the plug number of times between plug and socket, reach the effect of promoting product function.

For making above-mentioned purpose of the present utility model and structure can allow to be familiar with this operator more clear, special conjunction with figs. is described in detail the utility model with most preferred embodiment.
