Abstract
The invention discloses an electric coupler. An insulating base of the electric coupler is provided with a butt joint part, a substrate is arranged on the other side, adjacent to the butt joint part, of the insulating base, contact parts of multiple terminals are all located on the butt joint part, welding ends penetrating out of the external of the substrate are arranged at the tail ends of turning arms which turn and extend to the substrate from the contact parts, the welding ends are nineteen junctions welded to a circuit board and arranged in a staggered and spaced mode from front to back, the nineteen junctions form three rows in all, every three junctions form a group and are obliquely and sequentially arranged one by one and located in different rows, and the nineteenth junction and the eighteenth junction form a spacing distance which is located at a position of random rows. Accordingly, because of the design that a MiniHDMI socket matched with a slot of a shielding cover is laterally erected on the circuit board, widths needed by multiple junctions of the circuit board and circuit layout space can be reduced, overall circuit configuration can be appropriately arranged, and the freedom degree of the circuit board on circuit design is increased.
Description
Technical field
The present invention relates to a kind of electric connector, espespecially the slot of MiniHDMI socket cooperation shield shell is edge-on on wiring board, can make the required width of wiring board and configuration space more reduce, and the whole line configuring of can making appropriate arrangements, increase the degree of freedom in wiring board line design.
Background technology
Trend along with volume-diminished, computing and image processing just-in-time, memory body high capacity and the transmission speed high speed of computer, cathode-ray tube display is substituted gradually and eliminates, from giant displays such as desktop monitors to portable terminating machine display, all adopt now liquid crystal display, and because liquid crystal display can reach high brightness, low consumption electrically, the requirement such as high-res, become a part indispensable in daily life.
Moreover, the current general specification of display interface on the market, the VGA joint the most widely adopting is a kind of transmission means of analog signal in fact, and must first convert to, can be transferred to liquid crystal display after digital signal and show, and in the process of signal conversion, easily cause exhaustion and the distortion of signal, and along with the progress of hardware technology, transmission means demand for pure digi-tal constantly promotes, just having developed so-called DVI specification transmits in totally digitilized mode, even signal from display card, in digital mode, send, liquid crystal display also can directly receive in digitized mode, owing to having reduced transfer process once, nature has had greatest lifting in the quality showing.
Yet, due to VGA, the interface transmitting bandwidths such as DVI are limited, also thereby encountered development bottleneck, so the HDMI(High Definition MultimediaInterface of new spec) formulation of specification launches thus, for the shortcoming of display interface in the past, improved, and because the image signal of transmission does not need to there will not be through overcompression the shortcoming of image distortion, and can possess sound signal transfer function, be mainly used in box on machine, DVD player, Digital Television, PC, or even mobile phone, the electronic products such as digital camera all can be by the mutual transmission signal in HDMI interface, and image signal all can be presented with the highest resolution in transmission, user can be viewed and admired with best quality.
In addition, just with current HDMI connector compared to VGA, the connectors such as DVI, there is sizable change, little just meaning of its volume can be used on more electronic product, also can effectively reduce the cost in use, when not excessive HDMI connector is connected with wiring board, because the pin position arrangement mode of a plurality of terminals of many rows of adapter connector inside is different, and a plurality of contacts on wiring board need to be arranged fraction with the pin position of a plurality of terminals and match, therefore, the situation of short circuit while welding in order effectively to avoid wiring board to cause because a plurality of contact distances are too little, a plurality of contacts of general common plate line are mostly to carry out layout in the mode of whole row's linear array, but the wiring board width of this kind of layout type must be enough to hold all a plurality of contacts, more and more miniaturization of volume along with adapter connector, when if wiring board width limits to some extent, its layout type cannot be carried out, affect the degree of freedom in wiring board line design simultaneously.
Be with, in order effectively to solve the problem that above-mentioned wiring board layout type causes the restriction on width, just there is dealer to adopt the mode of dislocation to carry out layout, a plurality of contacts are carried out to layout to arrange the mode of the array that is parallel to each other more, and the institute of the ground contact in each crosspoint array allocation position is corresponding to the centre position between two signal contacts adjacent in an inferior crosspoint array, make every pair of signal contact and ground contact for forming an isosceles triangle or being interlacedly spaced shape setting, though it can make each adjacent contact distance more approaching, to reach the requirement on wiring board width, but this kind dislocation layout type, when the circuit at each contact place on wiring board is extended, must transfer and avoid the circuit at adjacent contact place, and cause the circuit distance at each two-phase abutment points place too approaching, while causing the contact welding on wiring board, compared to linear array layout type, more easily there is generation short circuit, the problem that fraction defective increases, needing to be engaged in this journey dealer redesigns effectively and is solved.
Summary of the invention
Main purpose of the present invention overcomes defect of the prior art, and a kind of electric connector with more rational layout type is provided.
The electric connector that the present invention proposes combination on insulating base frame is positioned with a plurality of terminals, and the welding ends at each terminal ends place is to be welded on wiring board to be spaced shape totally three rows' nineteen contact by being dislocation after forward direction, make in a plurality of contacts every three contacts be one group and sequentially obliquely gradually arrange and be positioned at different rows, nineteen contact forms a spacing distance and is positioned at arbitrary ranking with the 18 contact and puts.
Wherein, a plurality of terminals are a plurality of contacts on can terminated line plate, in 12 contacts of its first contact to the, every three contacts are one group of sequentially oblique ground contact and a pair of signal contact that is positioned at different rows that is gradually arranged with, in 18 contacts of the 13 contact to the, every three contacts are one group of sequentially oblique general contact that are positioned at different rows that are gradually arranged with, the general contact at nineteen contact place is better be embodied as be positioned at outermost or the same ranking of ground contact of inner side put.
Compared with prior art, the technical scheme that the present invention proposes can make required width and the configuration space of a plurality of contacts on wiring board more reduce, and the whole line configuring of can making appropriate arrangements, and increases the degree of freedom in wiring board line design.Simultaneously, also make the stretching Shi Buhui of extending of circuit at each contact place on wiring board and the circuit at adjacent contact place be in contact with one another, more can effectively save configuration space, and the space having more on wiring board can arrange more electronic components, reduce by this cost on using, have more the competitiveness of product.
