RCA connector

Abstract: The utility model relates to an automatic assembling and injection moulding compounding machine for an RCA (Radio Corporation of America) connector, comprising a base; wherein the base is provided with a rotating disc thereon, the rotating disc is connected with a screwing mechanism, clamping moulds are arranged on the rotating disc in each radial direction in order; and a needle feeding mechanism used for loading a copper core needle into the clamping mould, case feeding mechanisms used for loading copper cases into the clamping moulds, a positioning mechanism used for positioning the copper case, an injection moulding mechanism used for performing injection moulding for the copper core needle and the copper case on the clamping mould in order to form the connector, a discharging mechanism used for discharging the connector, and a controller used for coordinating operations of the each part are respectively arranged around the rotating disc The automatic assembling and injection moulding compounding machine of the utility model can automatically operate assembling and injection moulding of the RCA connector integrally, and can control the whole process reasonably, thereby greatly raising working efficiency, and reducing costs of various aspects, such as personnel and so on

Abstract: There is provided portable survey apparatus comprising a 20-core cable terminated on an interface module One of the conductors is designated as common Sixteen of the remaining conductors are designated as data lines 1 to 16 Spare conductors are designated as a diagnosis pair Data conductors are each terminated at the inner conductor of an RCA connector spaced along the cables, the shield or ground thereof being electrically connected to the common conductor, the connectors being securely maintained in position aligned parallel to the cable axis Drop leads having one end terminated in a corresponding connector are thereby adapted to engage the cable, the other end being terminated in a thumb-operated normally closed, momentary type microswitch An interface module comprises a substantially sealed enclosure connecting the cable and a port for connection to a PC The PC is used to generate a multiplex digital signal essentially comprised on an identity bit from 1 to 16 and a value of 0 or 1 A demultiplexer converts this data to a pin assignment and a pulse The demultiplexer continually pulses each data line When the interviewer puts a proposition one or more of the candidates will press the microswitch resulting in the data line corresponding to the person going open circuit that will be recorded as an event attributable to that data line, as well as recording the same or null events for the remaining data lines The data collected has relevance to both identity and value

Abstract: The present utility model discloses a self-locking structure of an RCA connector plugboard A plastic shell is provided with a shell plug foot and a pin foot for connecting a circuit board The tail end of a guide pillar of the shell plug foot is fork-shaped, and the tail end of the guide pillar of the pin foot is also fork-shaped The fork-shaped tail end of the guide pillar of the shell plug foot is provided with barbs, and the fork-shaped tail end of the guide pillar of the pin foot is also provided with barbs By adopting the plug circuit board, when a wave soldering is carried out, the fork-shaped guide pillars of the shell plug foot and the pin foot are pressed and gathered together, and the fork-shaped structures automatically bounce off when a plugging is completed, an RCA connector is hooked on the circuit board in advance by using the barbs of the fork-shaped tail ends, thereby guaranteeing that the RCA connector is free of skew or even shedding caused by shock or slight impact

Abstract: The utility model discloses a RCA (Radio Corporation Of America) connector. The RCA connector comprises a RCA female contact (1), a hollow-out shell (2) and a shell seat (3), a U-shaped PCB (Printed Circuit Board) board (4), a copper ring (5) as well as a copper needle (6); the RCA connector is characterized in that RCA female contact (1) is fixedly connected with the tail part of the shell (2); the U-shaped PCB board (4) is fixed in the shell (2) and connected with the RCA female contact (1) by an earth conductor (7) and a connecting conductor (8); the shell seat (3) is provided with a spring (9) and a guide groove (10); the copper ring (5) matches with the guide groove (10), is fixedly connected with the spring (9) and is connected with the earth conductor (7) in series; and the copper needle (6) is fixedly connected with the shell seat (3) and is connected with the connecting conductor (8) in series. Through structural creations on the copper ring and connecting relation, the utility model provides the RCA connector which cannot be loosened with an interface in the long-time plugging and unplugging process.
