Description

Stacked connector

Technical field

The utility model provides a kind of stacked connector; Especially refer to that insulating base frame is inner for containing signal module and electrical module; And the signal module is arranged with the circuit board of hyoplastron for being positioned at insulating base frame the place ahead docking groove; And make the crimp end in plural number butt joint terminal the place ahead of electrical module be positioned at another docking groove place, reach simple in structure, assembling easily and Stability Analysis of Structures, effectiveness with low cost with this.

Background technology

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

Moreover, along with computer or notebook computer development trend, the connector that makes computer-internal also with significantly dwindle, but connector promptly need be considered the signal interference problem that its galvanomagnetic effect produces in the computer downsizing; And the Electromagnetic Interference that generally can influence connector can be divided into following two kinds haply; One of which is for mainly transferring to the conducted interference (Conducted Disturbance) that connector produces via conductors such as the power circuit on the circuit board, signal circuits, and (Radiated Disturbance) disturbed in its two radiation of being caused for the radiation space that is transmitted to the electromagnetic wave form around the connector; In addition; Along with USB3.0 connector transmission speed significantly promotes; Its conducting terminal number increases and is densely distributed; As easy as rolling off a log because of between terminals of adjacent too near or terminal have any turnover or crooked signal when causing high-frequency signals to transmit to disturb (like the cross-talk of electrostatic interference, Electromagnetic Interference, impedance matching, noise jamming, adjacent conductive terminal etc.); The circuit impedance of USB3.0 connector and system board interface (Z) must be complementary; Must could effectively reduce electromagnetic interference (EMI) under the situation of this condition and reduce noise (noise) and disturb satisfying, can correctly carry out the signal transmission between USB3.0 connector and system board interface thereby make, to avoid influencing the whole normal operation of electronic installation (like computer, the network equipment etc.).

In addition; Along with the ripe development of network communications technology, make work, amusement, leisure and the study etc. of people in living all can brand-new progress be arranged through network, and along with the arriving in information explosion epoch; Make between men and can transmit required real time information, advertising or contact mail etc. each other through network communication; Simultaneously by the various information of Web search, real-time communication or game on line etc., let between people and the network relation more fervent and inseparable, so; Computer just need be provided with the connector that can be connected with external network, and the pattern of this kind network connector is main with the RJ45 specification mostly.

Yet; For actual needs and the consideration that reduces cost; Promptly there is the dealer to design the multi-port type connector of at least two kinds of different types connectors of this kind use, as can RJ port and USB port being incorporated on the same main body, comparatively general with this structural design; And combining structure is also simple and easy relatively many; See also Fig. 9, shown in Figure 10, be respectively the three-dimensional exploded view of known multiport type connector and the three-dimensional exploded view of USB module, wherein place, this insulating base frame A the place ahead is for being provided with docking groove A1 and being positioned at the accommodation space A0 that USB module B can accommodate in place, docking groove A1 below; And in docking groove A1, be equipped with plural bending butt joint terminal A11; And insulating base frame A outer cup is covered the location has shield shell C, and the pedestal B1 upper and lower place of USB module B institute tool utilizes the snaps into position mode to be assembled with hyoplastron B2 respectively, and on hyoplastron B2 bottom surface, is assembled with the first terminal group B21 and the second terminal group B22 of interleaved shape; And being positioned at wherein, there is base B3 hyoplastron B2 bottom for combining the location; In addition, pedestal B1 is outside to have metal iron-clad B4 for cover covers the location, and has in metal iron-clad B4 and can combine to be positioned the locating clamp plate B41 on the pedestal B1; And metal iron-clad B4 inner with the upper and lower two side places of locating clamp plate B41 between then be formed with the slot B40 that can supply hyoplastron B2 to be inserted into to be a vacant state in it respectively, just accomplish the group structure of known multiport type connector integral body.

Precisely because the mode of sharing same main body is when assembling; Promptly must RJ port and required each assembled component of USB port once be assembled and put in place, along with the electronic building brick that the multiport type connector day by day increases in the confined space, this kind structural design assembled component is more; Not only assembling procedure numerous and diverse with inconvenience outside; And mostly inequality because of the member of each one, make that the required quantity of mold developing is also more, thereby significantly increase mould and production cost; In addition; The inner the first terminal group B21 of hyoplastron B2 adds that second terminal group B22 group formation meets the USB3.0 specification, and the overall package space is quite limited, and must be accurate in the extreme; Otherwise just can cause terminal group distortion or skew; And stressed inequality and contact stress are in nonequilibrium state when docking mutually with external plug, and then influence terminal group and external plug and dock the impedance that produced and the size of contact area each other, and possibly cause the bad stability of its signal transmission; Be difficult to guarantee the locating effect that docks with external plug, then remain to be engaged in this journey dealer and design effectively again and solve.
