The invention relates to a serial-to-wireless communicator. The communicator comprises a bus structure, a processing apparatus, a wireless transceiver apparatus and a plurality of serial apparatuses, wherein the serial apparatuses are connected with the processing apparatus through the bus structure; and the processing apparatus is connected with the wireless transceiver apparatus. The processing apparatus obtains an uploading serial signal received by each serial apparatus through the bus structure, converts the uploading serial signal into an uploading signal identifiable by the wireless transceiver apparatus, and sends the uploading signal to the wireless transceiver apparatus. The wireless transceiver apparatus converts the uploading signal sent by the processing apparatus into a wireless signal, sends the wireless signal, converts the received wireless signal into a downloading signal, and transmits the downloading signal to the processing apparatus; and the processing apparatus receives the downloading signal sent by the wireless transceiver apparatus, converts the downloading signal into a downloading serial signal, and transmits the downloading serial signal to the corresponding serial apparatus through the bus structure, and the serial apparatus outputs the downloading serial signal. The processing apparatus is connected with the serial apparatuses through the bus structure, so that multi-serial data can be uploaded and downloaded, a multi-channel monitoring demand is met, and the usage cost is reduced.

The utility model relates to an abreast contact pin used for instrument detection. The abreast contact pin used for the instrument detection is formed by connecting a plurality of single pins abreast. Each single pin is composed of a fixed sheath, a telescopic sheath, a connection inserting groove, a connection plug, a contact pin, a connection pole and a wire winding fork. The telescopic sheath is arranged on the upper end of the fixed sheath in the same axial and the same radial mode, the connection inserting groove is arranged on a side edge of the fixed sheath in the radial direction, and the connection plug is arranged on the fixed sheath which is in an opposite side of the corresponding connection inserting groove. The connection pole is fixedly arranged inside the fixed sheath in the coaxial mode, the wire winding fork is arranged on the upper portion of the connection pole and placed inside the telescopic sheath, and the contact pin connected with the connection pole is fixedly arranged on the lower end of the fixed sheath in the coaxial mode. The abreast contact pin used for the instrument detection avoids various potential safety danger in a test and improves test efficiency. By means of the abreast contact pin structure, the number of the single pins can be combined freely according to specific demands and reliability is high.
