Description

Fool-proof positioning connector Technical Field The application relates to the technical field of connectors, in particular to a fool-proof positioning connector. Background The wire harness is widely applied to signal transmission or power connection of computers, household appliances, communication equipment, digital equipment and the like, and the terminal is used for connection between the wire harness and the connecting piece, so that the assembly of the electronic equipment is convenient, and the reliability of signal transmission or connection between the circuit boards inside the electronic equipment and the electronic equipment can be ensured. After the terminals, connectors and wires are pressed and assembled, the terminals, connectors and wires are required to be inserted into a PCB and then welded (soldered or electrically welded). The wire harness positioning standard is a terminal, the thimble of the terminal is thin and long in structure and easy to deform when being spliced with a PCB, so that the conduction stability of a product is affected, the wire harness structure is weaker than the PCB structure during welding, the thimble of the terminal of the wire harness is at risk of deformation and dislocation, and the conduction stability of the product is affected, so that improvement is needed. Disclosure of utility model In order to improve the structural strength of the wire harness and facilitate the wire harness to be better spliced and welded, the application provides a foolproof positioning connector. The fool-proof positioning connector provided by the application adopts the following technical scheme: the fool-proof positioning connector comprises a top frame, a bottom plate, a first side plate, a second side plate, a separation block, a limiting block and a positioning column, wherein the top frame is vertically opposite to the bottom plate, the first side plate is connected to one ends of the top frame and the bottom plate, and the second side plate is connected to the other ends of the top frame and the bottom plate; A cavity is formed between the top frame and the bottom plate, and the separation block is arranged in the cavity and separates the cavity into a limit groove, wherein one end of the limit groove is a wire harness plug-in port, and the other end of the limit groove is a terminal plug-in port; The limiting block is connected to the top frame and is positioned in the limiting groove, the limiting block is used for limiting a card on the terminal, the positioning column is connected to the second side plate, one end of the positioning column extends to the end where the terminal plug-in port is located, and the length direction of the positioning column is parallel to the length direction of the limiting groove and is used for being plugged on the PCB. Through adopting above-mentioned technical scheme, wire rod and terminal are connected through the mode of pressfitting earlier, and then insert the terminal from pencil grafting mouth place one end for the terminal gets into the spacing groove and reaches terminal grafting mouth department. When the wire harness is inserted into the wire harness insertion port, the clamping piece on the metal terminal is abutted to the limiting block, so that the wire harness is prevented from falling off. In order to facilitate understanding how the card on the metal terminal is clamped on the limiting block, reference may be made to a connector disclosed in the prior patent CN209183779U, and the description of the prior patent is combined to assist in understanding the principle of clamping the card. When the wire harness is to be plugged into an external PCB (the jack for plugging the adaptive positioning column is correspondingly increased on the PCB), the positioning column on the connector is utilized in the plugging process to realize quick positioning and plugging, and the connection part of the external soldering terminal and the PCB is utilized after the plugging is completed, so that the full fixation is realized. When inserting with the PCB board, through preventing slow-witted location structure on the connector, the thimble of terminal only plays auxiliary role, can prevent that the terminal from producing the possibility of deformation, improves the stability that the product switched on. Because the connector has a positioning structure during welding, the integral structure of the terminal and the PCB is not affected, and the product stability is good. Meanwhile, the fool-proof positioning structure of the connector is beneficial to assembling with the PCB, so that the assembling efficiency is improved, the cost is reduced, and the automation can be realized. Preferably, the separation blocks are arranged in a plurality of ways, each separation block is distributed in the cavity at intervals and forms a plurality of limiting grooves, the limiting blocks are arranged in parallel, and each limiting block is located in each
