Description
Technical field
The present invention relates to a kind of PC card connector assembly, particularly a kind of simple ground plate device that is used for the PC card connector assembly, this ground plate device is convenient to the PC card connector assembly is assembled on the printed circuit board.
Background technology
Traditional PC card connector assembly, such as the PC card connector assembly of accepting PCMCIA (connection of PCMCIA card interface) type card, it comprises that one has the connector of signal end (1B); With an independent ground plate; With some solder tauls.Described signal end (1B) is suitable for the signal contact of described card is connected to bottom circuit board corresponding signal circuit, described ground plate is included on the described card and the corresponding contacted earth terminal of grounding contact (1A), described some solder tauls are suitable for welding mutually with the ground path of bottom circuit board, with ground plate as the circuit board shared grounding.
Yet the ground plate of the PC card connector assembly of many prior aries is difficult to make and be difficult to finish assembling.And the ground plate of many prior aries comprises the guard shield part that covers connector signal end top, makes the inspection of welding of signal contact and bottom circuit board become very difficult like this, even this inspection is not sought after.This structure is to cause the condition that opens circuit with short circuit, and this does not wish to see.And, in the ground plate of some prior aries, be under the connector part with the location that is connected of printed circuit board (PCB), thereby the visuality inspection of earth terminal welding is very difficult.Simultaneously, the ground plate of many prior aries includes solder taul, this solder taul pass the circuit board thickness of slab and with the parts interference that places the circuit board downside, thereby, take the circuit board useable surface area, and be an impediment to the maximum closeness of realization parts in an electronic installation.At last, the ground plate of many prior aries one slide or horizontal direction on be mounted in their bottom connectors, thereby be not suitable for the automation assembling, only be build-up member in vertical direction.
Summary of the invention
The purpose of this invention is to provide a kind of simple ground plate device of the PC of being used for card connector assembly, this device has overcome the problems referred to above.That is, ground plate device of the present invention is easy to make and be easy to be assembled on the bottom connector.And described ground plate passes the top of connector and does not cover the upper part of the solder taul of signal end, thereby, allow visuality inspection is carried out in the welding of signal end, to prevent the short circuit condition generation.Welding between ground plate and circuit board is real mounted on surface, that is, being connected and fixed is outside the shared zone of connector, thereby, visuality inspection is carried out in the welding between ground plate and the circuit board.At last, in vertical direction ground plate is assembled on connector and the circuit board, and does not need level to assemble or engage, thereby be convenient to the automation assembling of connector assembly with connector.
A kind of PC card connector assembly that is used to connect the surface of a fastener and a printed circuit board according to the present invention, it comprises: a connector, signal end is installed on it, described signal end ends at a single file signal solder taul, so that be connected with corresponding signal lines surface on the printed circuit board (PCB), an and lengthwise ground plate that is installed on the described connector, it comprises a generally flat body, the pairing ground connection pole of some almost parallels, described pole and described body are made of one and stretch out before a side direction of body, and at each terminal mounted on surface ground connection solder taul of body, it extends with an angle backward and downwards from described body, cross the signal solder taul to be connected with the signal solder taul back corresponding earth connection direct surface of printed circuit board (PCB), it is characterized in that, when the PC card connector assembly is welded to the bottom circuit board, the pad that pad between signal solder taul and the circuit board can not be grounded between solder taul and the circuit board blocks, and the pad between ground connection solder taul and the circuit board can not blocked by connector.
Other purpose of the present invention, feature and advantage can be known from following detailed description in conjunction with the accompanying drawings and find out.
The present invention is considered to have special the statement within the scope of the appended claims of feature of novelty, and the present invention and purpose thereof and advantage from following description taken together with the accompanying drawings, are conspicuous, and same reference numerals is represented identical parts among the figure.

Embodiment
Referring to Fig. 3 to Fig. 5, the present invention has pointed out a kind of simple ground plate device of the PC of being used for card connector assembly, and this PC card connector assembly passes through the ground connection solder taul of mounted on surface at the two ends of ground plate, link to each other with the bottom circuit board.Ground plate 1 comprises a body 4, and it is suitable for being installed in the bottom connector 5.The pole 2 of some pairings roughly with the body same level on the compartment of terrain stretch out from body, and on a matched card such as pcmcia card, be suitable for matching mutually with corresponding grounding contact.Some through holes 6 be formed on the part of body 4 and with the part of connector 5 on match, be fixed in this to guarantee described ground plate structure.
Described two ground connection solder tauls 3 with the ground connection pole rightabout of pairing on stretch out from the two ends of body 4, and be suitable for being connected, so that the ground connection of blocking is shared by the earthed circuit of printed circuit board (PCB) with the corresponding ground path phase surface of printed circuit board.End at body 4, the coupling part of ground plate device and bottom circuit board, allow the ground plate device in the zone of described signal pole, to remain on opening-wide state, and not as ground plate device in the prior art (Fig. 1 and Fig. 2), thereby, because permission is convenient to the assembling of PC card connector assembly to the visual inspection of the welding of the signal end of connector 5, has reduced the generation of ground plate and signal end short circuit.
And, ground connection solder taul 3 is connected and fixed with the bottom circuit board, reached optimum visibility inspection, and allowed to have circuit board and/or other connector close packing of parts, and allowed connector assembly to be assembled on the circuit board automatically the welding of ground connection solder taul.Promptly, ground connection solder taul 3 is real mounted on surface with being connected of circuit board, that is, it need not penetrate circuit board plane, go up Anywhere thereby allow electric component with close packing to be placed on the circuit board opposed surface, and ground connection solder taul in prior art not.Because ground connection solder taul 3 is connected and fixed with circuit board, is in the size range of PC card connector assembly, each parts also can closely be placed the circuit board homonymy.And the welding of ground connection solder taul 3 after the PC card connector assembly is fixed on the circuit board, can be carried out visual inspection.
At last, the mounted on surface feature of described ground plate device, reaching other does not need to be bonded with each other with connector 5 levels or to assemble, and has allowed automation assembling between ground plate and the connector.That is, connector 5 can be installed on the circuit board in vertical direction, and ground plate is being installed on the same direction on the connector 5, on non-connector-circuit board installation direction, does not need to install or the assembling ground plate.
Although described the present invention, the present invention should be interpreted as to be confined to its described details in conjunction with its preferred forms.For the person of ordinary skill of the art, can have various differences to substitute and modification, thereby all these substitute and revise in the scope of the present invention that should be summarized in the claims qualification.
