Abstract: A structure of security and protection for connection socket includes a connection socket, a connection block, a resilient member, and a security member. The connection socket forms a receiving space and a slide channel. The slide channel is located at one side of the receiving space. The connection block is coupled to a rear end of the connection socket and forms a positioning section. The resilient member includes at least one resilient engagement section and is arranged in the positioning section of the connection block. The security member has an end forming a bar section that forms at a rear side thereof a barb section. The barb section is coupled to the at least one resilient engagement section of the resilient member. The bar section has two ends extending rearward to connect to a plate section. The security member is received in the slide channel of the connection socket.

Abstract: A lock and security structure for a connection receptacle includes a connection port, a pawl portion, and a lock and security portion. The connection port forms a receiving space and a slide channel in the receiving space. The pawl portion includes a fixed end and the pawl portion is located adjacent to an end surface of the connection port. The pawl portion forms at least one barb. The lock and security portion includes a bar portion and a board portion. The bar portion is formed on one end of the board portion. The lock and security portion is movable along the slide channel in the slide channel. When the lock and security portion is moved to a first position, the bar portion engages the pawl portion and when moved to a second position the bar portion disengages from the pawl portion.

Abstract: A structure of terminal holder of patch panel includes a holder body, which has a top surface forming a first wall. The first wall forms a plurality of through holes. The holder body has opposite ends each forming a second wall. At least one extension portion projects from at least one of the second walls of the holder body. A recess is formed between an underside of the extension portion and the corresponding second wall. As such, the performance of a cable fastener band for fastening and positioning can be improved and convenience of easy removal of the cable fastener band with tool cutting or manual removal is realized.

Abstract: A punch-down device includes a housing, a driving mechanism, and at least one punch-down member. The housing forms therein hollow channels. The driving mechanism includes a rotation shaft and at least one rotary wheel, which is connected and supported by the rotation shaft at a top portion of the housing. The rotation shaft has an end extending outside the housing to form a coupling section. Each of the rotary wheels has a surface forming two tracks and two pegs. The two pegs of one rotary wheel are received in the two tracks of an adjacent one of the rotary wheels. The punch-down member is received in the hollow channels to correspond to the rotary wheels and be driven to move by the rotary wheels. The punch-down member has lower ends forming conductor depression sections. As such, the punch-down device carries out an operation of punching down and depressing conductors, whereby the efficiency of punch-down operation is increased and the operation is easy and reliable positioning is achieved.

Abstract: A lock and security structure is provided for a connection receptacle and includes a connection port, a pawl portion, and a lock and security portion. The connection port forms a receiving space and a slide channel defined in a surface of the receiving space. The pawl portion includes at least one fixed end and the pawl portion is located adjacent to an end surface of the connection port. The pawl portion forms at least one barb. The lock and security portion includes a bar portion and a board portion. The bar portion is formed on one end of the board portion. The lock and security portion is movable along the slide channel in an extension direction of the slide channel. When the lock and security portion is moved to a first position, the bar portion engages the pawl portion. When the lock and security portion is moved to a second position, the bar portion disengages from the pawl portion.
