Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a substrate conformal connector. 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. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a substrate conformal connector, which 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 as follows: a conformal connector for a substrate, comprising 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-to-back direction. A plurality of terminals are correspondingly inserted into each terminal holding groove. The upper end of each terminal is capable of moving left and right within the terminal holding groove. Each terminal has one or a pair of upper elastic contact arms that can elastically deform in the left-to-right direction. Each upper elastic contact arm has a raised upper contact point on its upper sidewall. The paired upper elastic contact arms at the upper ends of each terminal form an upper elastic clamping portion, or two adjacent terminals with a single upper elastic contact arm together form an upper elastic clamping portion. The conductive substrate can be inserted between the two upper elastic contact arms forming the upper elastic clamping portion, and the upper contact points on the upper sidewalls of the two upper elastic contact arms can be tightly... The terminals are in close contact with the left and right side walls of the conductive substrate to achieve conductive connection between the terminals and the conductive substrate. The lower end of each terminal is provided with one or a pair of lower elastic contact arms that can elastically deform in the left and right direction. Each lower elastic contact arm has a lower contact point with a raised structure on its lower side wall. The lower elastic contact arms of each terminal form a lower elastic clamping part, or a single lower elastic contact arm of two adjacent terminals forms a lower elastic clamping part. A metal fastener is also provided and fixedly installed on the insulating body. The metal fastener includes a vertically extending contact plate and a welding plate. The contact plate of the metal fastener is inserted between the two lower elastic contact arms that form the lower elastic clamping part, and the lower contact points on the lower side walls of the two lower elastic contact arms can closely contact the contact plate of the metal fastener to achieve conductive connection between the terminals and the metal fastener.

The horizontal stop plate can extend into the notch and groove structure at the lower ends of the left and right side walls of the insulating body, and the horizontal stop plate stops on the bottom surface of the notch and groove structure to prevent the terminal from moving upward and detaching from the insulating body.

[0007] As a further improvement of this utility model, the lower end of the lower elastic contact arm and the horizontal stop plate together form an inverted T-shaped structure. One end of the horizontal stop plate extends towards the outside of the insulating body and is inserted into the notch structure at the lower end of the left or right side wall of the insulating body. The other end of the horizontal stop plate extends towards the inside of the insulating body. The lower contact point on the lower elastic contact arm is an inclined plate that extends upward from the other end of the horizontal stop plate. The inclined plates on the two lower elastic contact arms that make up the lower elastic clamping part form a flared structure with a lower opening size larger than the upper opening size.

[0008] As a further improvement of this utility model, the terminal has an upper elastic contact arm at the upper end and a lower elastic contact arm at the lower end; or, the terminal has an upper elastic contact arm at the upper end and a pair of lower elastic contact arms at the lower end; or the terminal has a pair of upper elastic contact arms at the upper end and a lower elastic contact arm at the lower end; two or three terminals are tightly fitted together to form a terminal group, and the terminal also has a through shaft hole in the middle position, and a pin is also provided. The pin is tightly inserted into the shaft hole of a group of terminals to fix the group of terminals together to form a whole, and each group of terminals is correspondingly inserted into a terminal retaining groove.

[0009] As a further improvement of this utility model, the shaft hole at the middle position of the terminal is a non-circular hole, and the cross-section of the pin is consistent with the shaft hole.

The left horizontal bending edge and the right horizontal bending edge can be flatly attached to the surface of the circuit board for welding connection.

[0011] 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. The upper end of the partition is lower than the upper end of the insulating main body. A slot for inserting a conductive substrate is formed in the middle of the terminal guard.

[0012] As a further improvement of this utility model, the lower end of the partition is higher than the lower end of the insulating main body. The upper end of the contact vertical plate of the metal fastener can be inserted into the insulating main body from bottom to top. The front and rear side walls of the upper end of the contact vertical plate of the metal fastener are respectively provided with a first buckle structure, and the inner side of the front and rear side walls of the insulating main body is provided with a second buckle mechanism. The first buckle structure and the second buckle structure can be fastened together to realize the fixed connection between the metal fastener and the insulating body.

[0013] As a further improvement of this utility model, the lower ends of the front and rear side walls of the insulating main body are formed with clearance notches. The upper end of the contact vertical plate of the metal fastener is smaller in the front-rear direction than the lower end in the front-rear direction.

The left and right elastic deformation of the lower elastic contact arm of the lower elastic clamping part realizes the overall left and right offset of the upper elastic clamping part.

Detailed Implementation

[0017] Example: A conformal connector for a substrate 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 retaining grooves 11 with openings at intervals along the front-to-back direction. A plurality of terminals 2 are correspondingly inserted into each terminal retaining groove 11. The upper end of each terminal 2 is capable of left-right movement within the terminal retaining groove 11. Each terminal 2 has one or a pair of upper elastic contact arms 21 capable of elastic deformation along the left-right direction at its upper end. Each upper elastic contact arm 21 has a raised upper contact point 211 on its upper sidewall. The paired upper elastic contact arms 21 at the upper end of each terminal 2 form an upper elastic clamping portion, or two adjacent terminals 2 with a single upper elastic contact arm 21 together form an upper elastic clamping portion. A conductive substrate 3 can be inserted between the two upper elastic contact arms 21 forming the upper elastic clamping portion, and the upper contact points 211 on the upper sidewalls of the two upper elastic contact arms 21 can tightly contact the left and right sidewalls of the conductive substrate 3. The terminal 2 is connected to the conductive substrate 3. The lower end of the terminal 2 is provided with one or a pair of lower elastic contact arms 22 that can elastically deform in the left and right direction. Each lower elastic contact arm 22 has a lower contact point 221 with a protruding structure on its lower side wall. The lower elastic contact arms 22 of each terminal 2 form a lower elastic clamping part, or two adjacent lower elastic contact arms 22 together form a lower elastic clamping part. A metal fastener 4 is also provided and fixedly installed on the insulating body 1. The metal fastener 4 includes a vertically extending contact plate 41 and a welding plate 42. The contact plate 41 of the metal fastener 4 is inserted between the two lower elastic contact arms 22 that form the lower elastic clamping part, and the lower contact points 221 on the lower side walls of the two lower elastic contact arms 22 can closely contact the contact plate 41 of the metal fastener 4 to realize the conductive connection between the terminal 2 and the metal fastener 4. The welding plate 42 of the metal fastener 4 is located on the outer side of the lower end of the insulating body 1 and can be welded to the circuit board for conduction.

[0018] A lower elastic clamping part is formed at the lower end of a single terminal 2 or two adjacent terminals 2 to elastically clamp the contact vertical plate 41 of the metal fixing part 4. While maintaining the connection between the terminal 2 and the metal fixing part 4, the connection between the terminal 2 and the circuit board is realized. Since the terminal 2 can move left and right in the terminal holding groove 11, when the conductive substrate 3 is inserted into the upper elastic clamping part formed at the upper end of a single terminal 2 or two adjacent terminals 2, the left and right positions of the upper elastic clamping part at the upper end of each terminal 2 are adjusted to adapt to the deformation part of the conductive substrate 3, 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. The upper elastic clamping part of the terminal 2 for elastically clamping the conductive substrate 3 is preferably formed by two upper elastic contact arms 21 to form a V-shaped structure with an upper opening. Its lower end is narrow, so that it forms a clearance space between itself and the inner side wall of the terminal holding groove 11 of the insulating body 1 for the elastic clamping conductive part of the terminal 2 to move left and right. The two upper elastic contact arms 21 form the two side walls of the V-shaped structure. The upper end of the upper elastic contact arm 21 forms an upper contact point 211 by bending inward toward the opening of the V-shaped structure. The terminal 2 is preferably a metal sheet integral stamping structure.

[0019] The lower ends of the left and right side walls of the insulating body 1 are respectively formed with notch and groove structures 12. The lower end of the lower elastic contact arm 22 of the terminal 2 is provided with a horizontal stop plate 222 extending in the left and right direction. The horizontal stop plate 222 can extend into the notch and groove structure 12 at the lower ends of the left and right side walls of the insulating body 1, and the horizontal stop plate 222 stops on the bottom surface of the notch and groove structure 12 to prevent the terminal 2 from moving upward and detaching from the insulating body 1. The horizontal stop 222 allows the terminal 2 to move or swing left and right within the terminal holding groove 11, but it cannot be pulled out upwards. Ideally, there should be a set gap between the lower elastic contact arm 22 of the terminal 2 and the side wall of the terminal holding groove 11 in the left and right directions, as well as between the horizontal stop 222 and the inner side wall of the notch structure 12. This allows the lower elastic contact arm 22 at the lower end of the terminal 2 to not only generate elastic deformation to allow the upper elastic contact arm 21 to swing left and right, but also to increase the range of motion of the upper elastic contact arm 21 at the upper end of the terminal 2 by utilizing the gap. Regardless of how the terminal 2 moves, the lower contact point 221 on the lower elastic contact arm 22 at its lower end is in close contact with the contact vertical plate 41 of the metal fixing member 4.

[0020] The lower end of the lower elastic contact arm 22 and the horizontal stop plate 222 together form an inverted T-shaped structure. One end of the horizontal stop plate 222 extends outward toward the insulating body 1 and is inserted into the notch structure 12 at the lower end of the left or right side wall of the insulating body 1. The other end of the horizontal stop plate 222 extends inward toward the insulating body 1. The lower contact point 221 on the lower elastic contact arm 22 is an inclined piece extending upward from the other end of the horizontal stop plate 222. The inclined pieces on the two lower elastic contact arms 22 that make up the lower elastic clamping part form a flared structure with a lower opening size larger than the upper opening size. The above structure facilitates the assembly of the metal fastener 4 and ensures stable contact with the lower contact point 221. The large contact area allows for the passage of large currents.

[0021] The terminal 2 has an upper elastic contact arm 21 at the upper end and a lower elastic contact arm 22 at the lower end; or, the terminal 2 has an upper elastic contact arm 21 at the upper end and a pair of lower elastic contact arms 22 at the lower end; or the terminal 2 has a pair of upper elastic contact arms 21 at the upper end and a lower elastic contact arm 22 at the lower end; two or three terminals 2 are tightly fitted together to form a terminal 2 group, and the terminal 2 also has a through shaft hole 23 in the middle position, and a pin 5 is also provided. The pin 5 is tightly inserted into the shaft hole 23 of a group of terminals 2 to fix the group of terminals 2 together to form an integral unit, and each group of terminals 2 is correspondingly inserted into a terminal retaining groove 11.

[0022] Two or three terminals 2 in a group are connected in series by a pin 5. The optimal solution is to form a group of three terminals 2. These three terminals 2 are arranged in a front-to-back direction. The front terminal 2 has an upper elastic contact arm 21 on the upper left and a lower elastic contact arm 22 on the lower right. The middle terminal 2 has an upper elastic contact arm 21 on the upper right and a lower elastic contact arm 22 on the lower left. The rear terminal 2 has an upper elastic contact arm 21 on the upper left and a lower elastic contact arm 22 on the lower right. In this way, two adjacent terminals 2 in the three terminals 2 form an opposite placement structure, which helps to maintain force balance and makes the terminal group 2 stably positioned in the terminal 2 fixing groove. When the conductive substrate 3 is inserted obliquely from above between the upper left elastic contact arm 21 and the upper right elastic contact arm 21 of the terminal 2, the terminal group 2 can automatically rotate to the basic conductive angle position and achieve a reliable connection.

[0023] The shaft hole 23 at the middle position of the terminal 2 is a non-circular hole, and the cross-section of the pin 5 is consistent with the shaft hole 23. This structure enables the pin 5 to be anti-rotatingly connected to each terminal 2.

[0024] The welding plate 42 at the lower end of the metal fastener 4 is formed by bending the lower end of the contact vertical plate 41 towards the left and right sides, respectively, creating a left horizontal bend and a right horizontal bend. These left and right horizontal bends can be flat against the circuit board surface for welding. The welding plate 42 of the metal fastener 4 is formed into multiple segments after being torn from the lower end of the contact vertical plate 41. Different segments are bent horizontally towards the left and right to achieve stable welding with the circuit board. For example, the front and rear ends may be bent towards the left, and the middle towards the right, or multiple segments may be bent alternately to the left and right. Alternatively, the metal fastener 4 can also be a T-shaped structure.

[0025] The insulating body 1 includes a rectangular insulating main body 13, partitions 14 arranged parallel to each other in the front-to-back direction and fixedly disposed within the insulating main body 13, and terminal guards 15 extending upward from the side walls of the insulating main body 13 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 14, as well as between adjacent partitions 14, form terminal holding grooves 11 of the insulating body 1. The upper height of the partitions 14 is lower than the upper height of the insulating main body 13. The terminal guards 15 have a slot 151 in the middle for inserting a conductive substrate 3. The terminal guards 15 on both the front and rear sides of the insulating body 1 protect the elastic clamping conductive parts of the protruding terminals 2, and the partitions 14 separate adjacent terminals 2.

[0026] The lower end of the partition 14 is higher than the lower end of the insulating main body 13. The upper end of the contact vertical plate 41 of the metal fastener 4 can be inserted into the insulating main body 13 from bottom to top. The front and rear side walls of the upper end of the contact vertical plate 41 of the metal fastener 4 are respectively provided with a first snap-fit ​​structure, and the inner side walls of the front and rear side walls of the insulating main body 13 are provided with a second snap-fit ​​mechanism. The first snap-fit ​​structure and the second snap-fit ​​structure can be fastened together to fix the metal fastener 4 to the insulating body 1. This structure allows the contact vertical plate 41 of the metal fastener 4 to be a one-piece structure, which can be smoothly inserted into the insulating body 1 without being blocked by the partition 14 inside the insulating body 1.

[0027] The lower ends of the front and rear side walls of the insulating main body 13 are formed with clearance notches 131. The upper end of the contact vertical plate 41 of the metal fastener 4 has a smaller dimension in the front-rear direction than the lower end in the front-rear direction. The lower end of the contact vertical plate 41 of the metal fastener 4 is inserted into the clearance notch 131 at the lower ends of the front and rear side walls of the insulating main body 13, and the stepped surface between the upper and lower ends of the contact vertical plate 41 of the metal fastener 4 stops on the bottom surface of the clearance notch 131. The above structure can achieve accurate and firm positioning of the insulating main body on the metal fastener 4, and is easy to assemble.

[0028] The first snap-fit ​​structure on the front-rear side wall of the upper end of the contact vertical plate 41 of the metal fastener 4 is an outwardly protruding inverted snap-fit ​​structure 411, and the second snap-fit ​​mechanism on the inner side of the front and rear side walls of the insulating main body 13 is an inner groove structure 132. The lower side wall of the inner groove structure 132 forms a hanging platform structure, and the inverted snap-fit ​​structure 411 on the upper side wall of the contact vertical plate 41 of the fastener forms a hook, which is hung on the hanging platform structure for positioning.
