Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of connection terminals, and in particular relates to a socket connection terminal. Background Art
[0002] With the development of electronic technology and the consideration of humanized design, sockets with zero insertion force structure are being widely used in daily life. They are simple and convenient to operate and can meet the needs of users for repeated plugging and unplugging. However, due to the reasons of fitting tolerance, the terminals of the existing zero insertion force socket connectors and the plug pins of the electrical appliances are often offset and cannot be accurately aligned, causing the plug pins of the electrical appliances to clash with the terminals when inserted, resulting in scratches or even deformation of the terminals. On the other hand, even if the plug pins of the electrical appliances that are not inserted in the normal position are barely inserted, there will be a problem of unstable contact due to excessive friction loss between the terminals and the plug pins during the sliding process to the predetermined position, which in turn affects the electrical connection performance between the electrical appliance and the circuit board. Utility Model Content
[0003] The purpose of the utility model is to provide a socket connection terminal, aiming to solve the technical problem in the prior art that the socket connector terminal with a zero insertion force structure and the plug pins of an electrical appliance often deviate and cannot be accurately aligned, causing the plug pins of the electrical appliance to clash with the terminal when inserted, resulting in scratches or even deformation of the terminal.
[0004] To achieve the above-mentioned purpose, an embodiment of the present invention provides a socket connection terminal, comprising a wire clamping portion and a probe guide portion, wherein one end of the probe guide portion is connected to one end of the wire clamping portion, and the probe guide portion is used for allowing the probe to pass through. The probe guide portion comprises a connecting plate and three elastic guide plates, wherein the connecting plates are respectively an upper connecting portion, a middle connecting portion, and a lower connecting portion from top to bottom. The upper connecting portion and the lower connecting portion are flipped upward around their connection ends with the middle connecting portion, and the upper connecting portion and the lower connecting portion are mirror images of each other. One side of the middle connecting portion is connected to the wire clamping portion, and the upper connecting portion, the middle connecting portion, and the lower connecting portion are respectively connected to the elastic guide plate at the end away from the wire clamping portion. The elastic guide plate is provided with a guide arc groove extending outward at the end away from the connecting plate.
[0005] Furthermore, the angle between the upper connection portion and the middle connection portion is 55 to 65 degrees, and the angle between the lower connection portion and the middle connection portion is 55 to 65 degrees.
[0006] Furthermore, the elastic guide plate further comprises a clamping piece and an elastic piece, wherein two ends of the clamping piece are respectively connected to the guide arc groove and the elastic piece, and the spacing between the clamping pieces is smaller than the spacing between the elastic pieces.
[0007] Furthermore, the connecting plate and each elastic guide plate are formed integrally.
[0008] Furthermore, the wire clamping portion includes a positioning arc groove and a positioning plate. Two ends of the positioning plate are respectively connected to the positioning arc groove and the probe guide portion.
[0009] Furthermore, a plurality of friction grooves are provided in the positioning circular arc groove, and the friction grooves are arranged at equal intervals on the inner side of the positioning circular arc groove.
[0010] Furthermore, mounting plates are extended from both sides of the positioning plate.
[0011] Furthermore, the positioning arc groove, the positioning plate and the probe guide are integrally formed.

When the plug pin of the appliance needs to be plugged into the socket connector and powered on, the plug pin of the appliance is inserted into the probe guide part and connected to the stripped end of the wire to power on. In the process of the plug pin of the appliance inserting into the probe guide part, the guide arc groove plays a guiding role, so that the plug pin of the appliance can be inserted into the probe guide part from the center of the probe guide part. In the process of inserting, the elastic guide plate is deformed, abutting the plug pin of the appliance, and preventing the plug pin of the appliance from scratching the inside of the probe guide part. The three elastic guide plates wrap the plug pin of the appliance, and the plug pin of the appliance is connected to the stripped end of the wire and powered on, avoiding the plug pin of the appliance from colliding with the probe guide part during the connection process, resulting in scratching the plug pin of the appliance or the probe guide part, thereby causing poor connection.
