Technical Field
The present invention relates to a connector including a scoop-proof device and more particular to a connector includes a SAS (Serial Attached SCSI) transmission interface.
Description of Related Art
With the rapid change of science and technology in the recent years and the high speed progression of cloud technology, there follows a great amount of data to be transported. Using connectors to achieve the data transportation has already become an indispensable and crucial technology at the time. From the early SCSI (Small Computer System interface) to the nowadays SAS (Serial Attached SCSI, serial-SCSI), with respect to the need of high speed data accessing, serial technology overcomes the bottleneck of conventional parallel technology, and provides a much faster signal transportation functionality. Also, SAS is able to support and is compactable with the SATA (Serial Advanced Technology Attachment) device, which indicates the advantageous wide ranging compatibility of the SAS.
When connectors are docked together, if the structures of the plug and socket are not designed with a suitable position guiding device, it might be impossible to precisely insert the circuit board of the plug into the cavity of the socket, or there might be an excessive angle. In the case that the plug docks obliquely with the socket instead of in a straight line facing towards each other, the terminals of the socket may become easily extruded into deformation or bended recession. Not only the situation increases the time requirement of docking, but the general structure of the plug or the socket might also be damaged.
As shown in
When the wire connector A100 is docked with a socket connector (not shown), the wire connector A100 will be guided by the guide surface A35 such that the wire connector A100 may be docked with the socket connector. The wire connector A100 can be guided to a correct position by the structure design of the guide surface A35 so as to make the wire connector A100 be docked with the socket connector successfully. In the aforementioned way, the time wasted to dock the socket connector with the wire connector A100 is greatly reduced, and the structure damages due to the mismatch of the socket connector and the wire connector A100 can be prevented.
In the foregoing technology, however, the wire connector A100 is guided by only one structure on the guide surface A35, so the accuracy of guiding and matching has not yet achieved a satisfying level. Most designation of size specification of two docking structures do not strictly cooperate with each other, as there is a buffer space preserved to make sure that the errors generated in the manufacturing process will not further result in a docking failure or over-tightness. Accordingly, the wire connector A100 may be obliquely docked with the socket connector (not shown), so the mismatch issue during the docking phase is not entirely solved by the wire connector A100 and the socket connector. There still exists the problem that the socket connector may be docked with the wire connector A100 with an excessive angle, in which case the inside terminals of the socket connector are prone to be damaged by the bumping of the wire connector A100, and thus further reduces the life-span of the connector A100.
Since the prior art is unable to provide an adequate method to prevent the inside terminals of the socket connector from being recessed or being extruded by external forces, an improved technical solution to overcome the difficulty to satisfy the practical demand in the industry is in a desperate need.
The invention provides a connector. The connector includes a scoop-proof device. When the connector docks with another connector, the scoop-proof device can effectively prevent the connector from being inserted with an offset angle, thus avoiding the inner-structure damage generated in the docking phase of the two connectors.
According to another aspect of the present invention, a connector is provided. The connector includes a scoop-proof device which is one or more guides. When the connector is going to share high frequency signals with the docking connector, the guides can guide the connector and the docking connecter to face each other and to be docked straightly. By reducing the occasions that connectors are docked with each other obliquely, the inside terminals are not bumped and damaged as often, thus generally improving the docking quality of the connectors.
To achieve the aforementioned purpose, a connector is provided in the present invention. The connector includes an insulating housing, a circuit board, and a plurality of guides. The circuit board has a front end configured to dock with a docking connector and a back end distal to the docking connector. A plurality of gold fingers is disposed at the front end and exposed at a surface of the circuit board. The back end is embedded in or protruded from the insulating housing. The front end extends out of the insulating housing. Each of the guides is partially embedded in or protruded from the insulating housing and parallel to the circuit board, wherein each of the guides is disposed at one of opposite sides of the insulating housing and extends outwardly towards the docking connector. Each of the gold fingers may be electrically connected to the docking connector. Wherein, each of the opposite sides of the insulating housing is disposed with at least one bump extending outwardly, and each of the guides is partially embedded in or protruded from a side of a corresponding one of the bumps. Each of the guides is partially embedded in or protruded from the insulating housing. The embedding method may be an insert molding method that inserts and molds each guide at a corresponding one of the bumps and a corresponding one of the insulating housing. In addition, each of the guides is a rectangular bar made of a metal material, and a side surface of each of the guides adjacent to the circuit board has an unfilled corner for the convenience of the inserting and molding of the guides into the bumps.
In the present invention, each of the guides has an exposed part exposed from the insulating housing, and the exposed part of each of the guides extends outwardly towards the docking connector and approach a location of the gold fingers on the circuit board, so as to form the guides as a scoop-proof device. The connector and the docking connector are docked together by the guidance of the guides located at the two sides of the insulating housing, so as to prevent the connector from docking with the docking connector with an offset angle. In addition, the guides may also be formed by vertically extending the two sides of the insulating housing of the connector outwardly towards the docking connector, so that the guides is and the insulating housing are formed in one piece, thus generally improves the stability of the guides on the connector.
In the present invention, a flexible piece and a plurality of wires are disposed at the connector. The flexible piece is installed at the top surface of the insulating housing. The flexible piece is used to engage with the docking connector. Each of the wires is electrically connected to the circuit board. Each of the wires is embedded in or protruded from the insulating housing. The embedding method may be an insert molding method which inserts and molds each of the wires into the insulating housing. A fixing slot is disposed at the top surface of the insulating housing and the flexible piece is accommodated and installed in the fixing slot. At least one engaging part is disposed at the flexible piece and the engaging part is used to engage with the docking connector.

In comparison with the prior art, by using the guides in the connector to match with the docking connector and as a scoop-proof device of two connectors, the guide structures of the guides may effectively enhance the assembly tolerance. Accordingly, the angle and the offset position generated during the docking phase may be corrected, and the correction may prevent the docking terminals of the docking connector from being damaged and deformed by the excessive angle of the insertion of the circuit board. As a result, two connectors dock with each other more successfully, thus effectively increase the life-span of the connector and make the connector more adaptive to the demands of the majority of users.
