摘要:
An interface arrangement is connected between a scanning head for electro-optically reading bar code symbols and a host device having a host processor operative for processing signals with a predetermined data exchange format. The interface arrangement includes a housing; a first connector on the housing for direct connection to the host device; a second connector on the housing for direct connection to a head cable connected to the scanning head; and a conversion circuit within the housing for converting decoded signals generated in the head into data signals having a format compatible with the predetermined data exchange format of the host processor.
摘要:
An electrical coupling arrangement, particular for digital transfer, has a female connector and a male connector. Each connector has an electrical coupling portion via which the data are transferred. The connectors are held together by means of a latching arrangement consisting of a pair of fixed latching posts on the male connector which mate with a corresponding pair of flexible latching sleeves which are molded within the body of the female connector. The self-latching action means that the coupling may be effected rapidly but also securely. The invention extends to a method of manufacture, with the body of the female connector being molded around latching sleeves which may have a lower melting point than the material making up the body itself.

Various optical components of an electro-optical system for reading coded indicia are mounted on a chassis snap-mounted in a housing. The optical components are supported by the chassis at an elevation relative to a printed circuit board snap-mounted to the chassis. The optical components are automatically adjusted in a test fixture.
