Description

Electric connector

Technical field

The utility model provides a kind of electric connector, especially refer to that the hyoplastron inside that insulating base frame extends contains terminal base, a plurality of flexible terminals that its hyoplastron and terminal base inside wears respectively and fixed terminal can be formed well cover and isolate, and in the assembling contraposition all quite simple and easy fast.

Background technology

Electronics technology fast development now, making the computer kenel is to develop into volume notebook computer less, easy to carry by desktop computer, and each corner in the ubiquity society, and when the user desires to carry out the transmission of data, signal or is connected with other peripheral equipments, promptly need so-called peripheral equipment interface, use and generally the peripheral equipment interface is the most generally and widely popular on the market, still just with USB (USB) as main flow.

Yet electric connector is generally and is welded in electronic installation (as computer, display or mobile phone etc.) on the inner circuit board, and because of having other electronics spare parts on the circuit board, along with the computer volume inside is dwindled, so that also crypto set more of the distance between each electronic component, accelerate demand in order to satisfy the computer execution speed, the frequency that its integrated circuit produced improves gradually, cause the Electromagnetic Interference (EMI) on the circuit board also to improve relatively, thereby cause Abort Electronic Assembly, influence electric connector signal transmission quality, so all can cover the shield shell that is covered with metal material usually in the electric connector outside, just can use as ground connection or electromagnetic protection (EMI suppression) effect by shield shell.

But along with old USB2.0 electric connector transmission speed is not enough, drive the place that the running power shortage is undoubtedly maximum technical bottleneck, so, just there is the dealer to develop the USB3.0 electric connector, not only be compatible to the USB2.0 electric connector downwards, it is required to satisfy promptly to increase by row's terminal group on existing USB2.0 connector basis, and the transmission speed that each USB3.0 connector is the highest can reach 5.0Gbps, see also as Fig. 7, shown in 8, be existing vertical view and side cutaway view, it is to adopt two row's terminal group to inlay shoot mode and colloid one-body molded (Insert Molding), but aforesaid electric connector in use, still have many disappearances, existing division is as follows:

Existing two row's terminal group adopt inlay shoot mode and must be earlier in the mould part as mold insert while pressing terminal and terminal separately, to cause the terminal part to be in no colloid guard mode, and behind the colloid ejection formation, make a plurality of USB3.0 terminals of row on it have two places directly to expose (as shown in Figure 7), and when the external electric connector inserts, because distance is very near between USB3.0 terminal and external electric connector shell, and therefore locate often need be subjected to the plug contact, so can't stick on mylar film (Mylar, for the mylar material is made) isolated, therefore, be easy to generate the high-frequency electromagnetic wave interference when when work, instantaneous pressure or noise occurring and cause electrically bad, and reduce the stability that signal transmits, simultaneously also with the critical safety of using to integral body; Moreover, it adopts the efficient of inlaying in the shoot mode manufacturing processing also relatively poor, and the stock utilization of terminal group reduce (because of step pitch between terminal need with increasing, after making things convenient for mould to separate terminal, carry out the colloid ejection formation), directly cause whole manufacturing cost to improve, and be unfavorable for a large amount of productions, desire most ardently the place that research improves direction and remain to be engaged in this journey dealer.

Therefore, the creator is because above-mentioned problem and disappearance, is collect related data via assessing in many ways and consider, and utilizes the research and development experience for many years of engaging in the industry constantly to study and revise, and the beginning is designed the novel birth of this kind electric connector.
