Embodiment
For the ease of understanding the present invention, below with reference to relevant drawings, coaxial connector is described more fully.The first-selected embodiment of coaxial connector is given in accompanying drawing.But coaxial connector can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the disclosure of coaxial connector more comprehensively thorough.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present invention understand usually.The object of the term used in the specification of coaxial connector herein just in order to describe specific embodiment, is not intended to be restriction the present invention.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
It is to be noted, the utility model is the structure-improved carried out based on UniversalSerialBusType-CCableandConnectorSpecification (Rev.1.0) standard (hereinafter referred to as " standard ") of USB-IF announcement, therefore, in standard content, the content of regarding connector is also regarded as a part herein.
The USB connector 00 with high frequency performance improvement middleware of the utility model preferred embodiment as shown in Figure 1, this USB connector 00 is completely according to socket (or female seat) interface of standard, for being installed in printed circuit board, mate with the other side's connector (being called plug or male, not shown) and be electrically connected.With reference to Fig. 1, and composition graphs 2, shown in Fig. 3, the regulation of associated socket in the standard announced according to USB-IF, this USB connector 00 comprises shell, be fixed on the insulating body in described shell, be fixed on described insulating body and in arrange up and down distribution terminal and be fixed on described on, middleware between lower row's terminal, from standard, described terminal comprises multiple Difference signal pair terminal and power supply or ground path terminals (because the utility model is the structural improvement that the high frequency performance for improving Difference signal pair terminal is made for middleware, therefore, the part improveing innovative point irrelevant with middleware is not described further at this paper entire chapter, as understood specifically see the related content of standard), only be illustrated for differential pair terminal.
As Fig. 2, and it is shown in Figure 3, Difference signal pair terminal 10 comprises the contact site 11 in electrical contact with the other side's bonder terminal, for the weld part 12 that is connected with printed circuit board soldering and the joint portion 13 connecting described contact site 11 and weld part 12, described middleware 20 is formed by bending by sheet metal, the rear portion 22 comprising flat anterior 21 and formed by right-angle bending by the ora terminalis of front portion 21, the both sides of described middleware 20 are provided with buckle 23, for being fixed in insulating body, described middleware 20 is also provided with combined hole 24, for strengthening the fixing and bonding force of middleware and insulating body further, as shown in Figure 3, described middleware 20 is being provided with multiple slotted eye 210 according to impedance matching principle corresponding to described Difference signal pair terminal 10 position, in the present embodiment, described slotted eye 210 is interconnected by the rectangular channel 212 that the width at the wider rectangular channel 211 of front width and rear portion is narrower and is formed as one, the positive contraposition that described slotted eye 210 is arranged at described contact site 11 is set up (namely immediately below upper row's terminal or directly over lower row's terminal position), like this, if when the impedance of upper row's terminal or lower row's terminal is bigger than normal, resistance value can be made to pull down to predetermined value by the size of slotted eye 210 being diminished in response to ground, if when the impedance of upper row's terminal or lower row's terminal is bigger than normal, resistance value can be made to be pulled upward to predetermined value greatly by the size of slotted eye 210 being become in response to ground, thus make Difference signal pair terminal 10 obtain desirable impedance matching effect, realize the high frequency performance optimization of USB connector 00.
Further, the rear portion 22 of described middleware is arranging slotted eye 210 ' corresponding on corresponding described Difference signal pair terminal position, and the latter half of the front portion 21 of described middleware also arranges slotted eye 210 in relevant position " interval of impedance adjustment can be increased further and improve the possibility that high frequency index optimizes further.
Experience is known by experiment, for realizing preferably high frequency performance improved effect, the length of anterior rectangular channel 211 should be arranged to the length of the rectangular channel 212 being greater than described rear portion, in addition, when the width of the rectangular channel 211 of this front portion is 1.4 times of the width of the rectangular channel 212 at rear portion, impedance matching can reach optimum state, what deserves to be explained is, described slotted eye 210 is being positioned at the change of the adjustment near the contact site 11 of terminal on the impact of high frequency performance comparatively greatly, improves comparatively really the most obvious.
On the other hand, be simplification and the manufacture convenience of implementation structure, described middleware also can be provided with slotted eye 210 (shown in Figure 2) in the forward position of the described power supply of correspondence or ground path terminals.
In sum, USB connector of the present utility model is optimized adjustment by the impedance of specification to Difference signal pair terminal of multiple slotted eyes that middleware is arranged, thus realizes the object of high frequency performance improvement.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this specification is recorded.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
