Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a substrate connector with improved structure. Background Technology

[0002] Currently, the metal terminals of the substrate connector are composed of a retaining part, an elastic clamping conductive part, and pins. The three are fixedly connected to form an integrated structure. The retaining part is fixedly positioned between the metal terminal and the insulating body by inserting barbs into the retaining groove of the insulating body. The pins extending out of the outside of the insulating body are used for soldering the PCB board. The elastic clamping conductive part clamps the conductive substrate with a pair of elastic contact arms to achieve signal transmission.

[0003] When metal terminals establish an electrical connection between a conductive substrate and a PCB board, various processing and assembly deviations can cause a misalignment between the socket position of the connector's elastic contact arms soldered onto the PCB board and the position of the conductive substrate. This makes it difficult to smoothly insert the conductive substrate into the socket formed between the connected elastic contact arms. In other words, existing technology cannot accommodate manufacturing deviations of the conductive substrate. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a substrate connector with improved structure. This improved substrate connector can absorb manufacturing deviations of the conductive substrate and realize a smooth electrical connection between the conductive substrate and the PCB board.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an improved substrate connector, including an insulating body made of insulating material and a plurality of terminals made of conductive material. The insulating body has a plurality of terminal holding grooves with upper and lower openings arranged at intervals along the front-back direction. The terminals include elastic clamping conductive parts, floating connecting parts, holding parts and welding pins. The holding parts of each terminal can be fixedly inserted into the terminal holding grooves of the insulating body to achieve a fixed connection between the terminal and the insulating body. The welding pins are fixedly connected to the lower end of the holding parts. A welding plane is formed on the lower side of the welding pins, extending out of the lower end of the insulating body. The lower end of the floating connecting part is fixedly connected to the holding part. The upper end of the floating connecting part is fixedly connected to the lower end of the elastic clamping conductive part. The floating connecting part can generate elastic deformation in the up-down and left-right directions when subjected to force. The elastic clamping conductive part can tightly clamp the left and right side walls of the conductive substrate to achieve a conductive connection between the terminal and the conductive substrate.

[0006] As a further improvement of this utility model, the floating connection part is an S-shaped structure formed by reciprocating bending from left to right.

[0007] As a further improvement of this utility model, the terminal holding part includes a U-shaped holding body and barbs provided on the outer side of the two side walls of the U-shaped holding body. The barbs extend outward from top to bottom. The barbs can be embedded in the left and right side walls of the terminal holding groove of the insulating body so that the holding part cannot move downward relative to the holding groove. Two welding pins are integrally formed on the lower outer side of the two side walls of the U-shaped holding body. The two welding pins extend horizontally in the left and right directions and stop on the lower surface of the insulating body. The lower end of the floating connection part is integrally formed on the inner bottom surface of the U-shaped holding body.

[0008] As a further improvement of this utility model, the upper end of the U-shaped structure of the holding body forms a flared structure through an inclined surface.

[0009] As a further improvement of this utility model, the elastic clamping and guiding part includes a V-shaped piece integrally formed on the upper end of the floating connecting part. The two side walls of the V-shaped piece form elastic contact arms that can swing elastically left and right. The upper end of the elastic contact arms is respectively formed with clamping contact parts that protrude toward the inside of the V-shaped opening.

[0010] As a further improvement of this utility model, a horn-shaped substrate insertion port with an upper opening larger than the lower opening is formed between the clamping contact portions of the two elastic contact arms.

[0011] As a further improvement of this utility model, the terminal is a one-piece stamped structure made of metal sheet.

[0012] As a further improvement of this utility model, the insulating body includes a square-shaped insulating main body, partitions arranged parallel to each other in the front-back direction and fixedly disposed in the insulating main body, and terminal guards extending upward from the side walls of the insulating main body in the front-back direction. The gaps between the side walls of the insulating body in the front-back direction and the partitions, as well as between adjacent partitions, form terminal holding grooves of the insulating body. A slot for inserting a conductive substrate is formed in the middle of the terminal guard.

[0013] As a further improvement of this utility model, the partition is a long strip-shaped flat structure with the upper end lower than the upper end of the insulating main body and the lower end higher than the lower end of the insulating main body, and the lower edge of the left and right inner sidewalls of the insulating main body is provided with a chamfer structure.

[0014] The beneficial technical effects of this utility model are as follows: The terminal of this utility model is connected to the holding part and the elastic clamping conductive part by the floating connection part, so that the elastic clamping conductive part can float elastically up and down and left and right, realizing the absorption of the torsional deviation of the conductive substrate in the up and down and left and right directions by the connector. When the conductive substrate is inserted at an angle, the terminal can also automatically twist to the position of the conductive plate and achieve a reliable connection.

[0028] Example: An improved substrate connector includes an insulating body 1 made of insulating material and a plurality of terminals 2 made of conductive material. The insulating body 1 has a plurality of terminal holding grooves 11 with openings at intervals along the front-to-back direction. Each terminal 2 includes an elastic clamping conductive part 21, a floating connection part 22, a holding part 23, and a soldering pin 24. The holding parts 23 of each terminal 2 can be fixedly inserted into the terminal holding grooves 11 of the insulating body 1 to achieve a fixed connection between the terminal 2 and the insulating body 1. The soldering pin 24 is fixedly connected to the lower end of the holding part 23, and a soldering plane is formed on the lower side of the soldering pin 24 extending outward from the lower end of the insulating body 1. The lower end of the floating connection part 22 is fixedly connected to the holding part 23, and the upper end of the floating connection part 22 is fixedly connected to the lower end of the elastic clamping conductive part 21. The floating connection part 22 can elastically deform in the up-down and left-right directions under force. The elastic clamping conductive part 21 can tightly clamp the left and right side walls of the conductive substrate 3 to achieve a conductive connection between the terminal 2 and the conductive substrate 3.

[0029] By providing a floating connection part 22 between the holding part 23 and the elastic clamping conductive part 21 of the terminal 2, the elastic clamping conductive part 21 can move elastically up and down and left and right within a certain range, thereby changing the position of the elastic clamping conductive part 21 of the terminal 2, thereby adapting to the manufacturing deviation of the conductive substrate 3, realizing the smooth insertion of the conductive substrate 3, and ensuring that the conductive substrate 3 and the PCB board establish a stable electrical connection.

[0030] The floating connection part 22 is an S-shaped structure formed by reciprocating bending from left to right. Through the continuous left and right bending of the tortuous structure, the floating connection part 22 can elastically deform in the left and right and up and down directions, thereby allowing the elastic clamping conductive part 21 to move or swing left and right with the conductive substrate 3. The floating connection part 22 can also be bent to form a C-shaped structure or an inverted W-shaped structure, etc.

[0031] The holding part 23 of the terminal 2 includes a U-shaped holding body and barbs 231 on the outer side of the two side walls of the U-shaped holding body. The barbs 231 extend outward from top to bottom. The barbs 231 can be embedded in the left and right side walls of the terminal holding groove 11 of the insulating body 1 so that the holding part 23 cannot move downward relative to the holding groove. Two welding pins 24 are integrally formed on the lower outer side of the two side walls of the U-shaped holding body. The two welding pins 24 extend horizontally in the left and right directions and stop on the lower surface of the insulating body 1. The lower end of the floating connection part 22 is integrally formed on the inner bottom surface of the U-shaped holding body. After terminal 2 is inserted into the terminal holding groove 11 of the insulating body 1 from bottom to top, the holding part 23 of terminal 2 is inserted into the terminal holding groove 11. The two side walls of the U-shaped structure of the holding part 23 form a cantilever structure. After the barbs 231 protruding outward on it contact the inner side wall of the terminal holding groove 11, the two side walls of the U-shaped structure of the holding part 23 deform inward to avoid it. When the holding part 23 of terminal 2 is inserted into place, the welding pin 24 at the lower end of terminal 2 is pressed tightly against the lower end surface of the insulating body 1. The barbs 231 on the side wall of the holding part 23 of terminal 2 are stuck into the inner side wall of the terminal holding groove 11 of the insulating body 1. Terminal 2 cannot be pulled out upward or downward, thus realizing the fixed connection and positioning of terminal 2 and insulating body 1.

[0032] The upper end of the U-shaped structure of the retaining body forms a flared structure through an inclined surface.

[0033] The elastic clamping conductive part 21 includes a V-shaped piece integrally formed on the upper end of the floating connection part 22. The two side walls of the V-shaped piece form elastic contact arms that can swing elastically left and right. The upper ends of the elastic contact arms are respectively formed with clamping contact parts 211 protruding towards the inside of the V-shaped opening. By forming a V-shaped structure, the elastic clamping conductive part 21 has a small width at its lower end, which creates a clearance space between it and the inner side wall of the terminal holding groove 11 of the insulating body 1, allowing the elastic clamping conductive part 21 of the terminal 2 to move left and right. The upper ends of the two side walls of the V-shaped structure of the elastic clamping conductive part 21 are bent towards the inside of the V-shaped structure opening, reducing the opening of the V-shaped structure and forming the clamping contact parts 211 for clamping the conductive substrate 3.

[0034] A flared substrate insertion port with an upper opening larger than the lower opening is formed between the clamping contact portions 211 of the two elastic contact arms. The flared port structure facilitates the smooth insertion of the conductive substrate 3 even when it is tilted.

[0035] The terminal 2 is a one-piece stamped structure made of metal sheet.

[0036] The insulating body 1 includes a rectangular insulating main body 12, partitions 13 arranged parallel to each other in the front-to-back direction and fixedly disposed within the insulating main body 12, and terminal guard plates 14 extending upward from the side walls of the insulating main body 12 in the front-to-back direction. The gaps between the side walls of the insulating body 1 in the front-to-back direction and the partitions 13, as well as between adjacent partitions 13, form terminal holding grooves 11 of the insulating body 1. The terminal guard plates 14 have a slot 141 in the middle for inserting a conductive substrate 3. The terminal guard plates 14 on both the front and rear sides of the insulating body 1 can protect the elastic clamping conductive parts 21 of the protruding terminals 2.

[0037] The partition 13 is a long strip-shaped flat structure with its upper end lower than the upper end of the insulating main body 12 and its lower end higher than the lower end of the insulating main body. The lower edges of the left and right inner sidewalls of the insulating main body 12 are provided with chamfered structures, which facilitates the insertion and assembly of the terminals 2.
