Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and more specifically to a high-speed electrical connector terminal press-in adjustment device. Background Technology

[0002] High-speed electrical connectors typically consist of a plastic body and two rows of terminals. The two rows of terminals are mounted inside the plastic body. The contact portion of the terminals is electrically connected to the data chip, and the pins of the terminals are soldered to the printed circuit board. This allows the data chip to transmit data with other electronic components via integrated circuits on the circuit board.

[0003] There are three main methods for soldering high-speed electrical connectors to printed circuit boards (PCBs): through-mount soldering, where the terminals' legs pass through mounting holes on the PCB and are then soldered; clamp soldering, where the solder feet of two rows of terminals clamp the PCB; and surface mount soldering, where the solder feet of two rows of terminals are bent at right angles to form a flat surface and then soldered onto the PCB. For surface mount soldering connectors, the coplanarity of the terminal solder feet has a significant impact on the soldering effect. Terminals outside this range may experience problems such as cold solder joints, thus affecting the stability of data transmission. DDR series electrical connectors are approximately 100mm long, with more than 100 terminals per row. Due to factors such as equipment processing precision, there may be varying degrees of coplanarity deviation among terminals at different locations, making it difficult to simultaneously adjust the coplanarity of all terminals. Summary of the Invention

[0004] To ensure precise adjustment of the coplanarity of the solder pads of high-speed electrical connector terminals, this invention provides a segmentally adjustable high-speed electrical connector terminal press-in adjustment device.

[0005] The technical solution adopted by this utility model is as follows: A high-speed electrical connector terminal press-in adjustment device includes a horizontal flow channel within which the electrical connector moves horizontally. A feeding structure is installed at one end of the flow channel, which actuates the electrical connector to slide within the channel. A positioning structure is located on the front side of the flow channel, and an adjustment structure is located on the rear side. The positioning structure includes a front bracket and a tongue mounted on the top surface of the front bracket. A horizontal front linear slide rail is installed between the tongue and the front bracket. The adjustment structure includes a rear bracket, with an adjustment assembly mounted on its top surface. A rear linear slide rail is installed between the adjustment assembly and the rear bracket. During press-in adjustment, the tongue and adjustment assembly slide towards the electrical connector along their respective linear slide rails. The adjustment assembly includes a back plate, multiple adjustment modules, and a mounting plate. The mounting plate is mounted on the front side of the back plate, facing... The back plate has a mounting groove on its surface, with the top of the mounting groove extending through it. Multiple adjustment modules are arranged side by side and inserted into the mounting groove. The adjustment modules are confined within the cavity formed by the mounting groove and the back plate, with the top of the adjustment modules extending outward from the outside of the mounting groove. The back plate has multiple vertical adjustment grooves, with each adjustment module corresponding to one adjustment groove. The back of each adjustment module is fixed to the back plate by screws passing through the adjustment grooves. The lower half of the front of the adjustment module has a multi-step surface from top to bottom. The mounting plate has a horizontal groove corresponding to the length of the electrical connector at the position where the height of the terminal of the electrical connector is located. During the pressing adjustment, the edge of the terminal strip passes through the horizontal groove and makes contact with the adjustment component. When the adjustment module is misaligned vertically, the pressing depth of the terminal at different positions is adjusted by using different step surfaces.

[0006] Furthermore, the back of the adjustment module is provided with a vertical protrusion, and the back plate is provided with a limiting groove that corresponds to and cooperates with the protrusion.

[0007] Furthermore, a handle is installed on the top surface of the adjustment module.

[0008] Furthermore, the upper half of the front of the adjustment module is provided with scales corresponding to the multi-level stepped surfaces.

[0009] Furthermore, the tongue is mounted on the front linear slide rail via a tongue holder, and the adjustment assembly is mounted on the rear linear slide rail via an adjustment seat. The tongue holder and the adjustment seat are respectively connected to a cam mechanism.

[0010] Furthermore, the cam mechanism includes a roller, a cam, a cylinder, and a support base. The roller is rotatably mounted on the side of the tongue seat and the adjusting seat away from the electrical connector. The cam is mounted on the corresponding support base via a vertical linear slide rail. The cylinder is vertically positioned and fixedly connected to the cam. During the extension and retraction of the cylinder, the cam cooperates with the roller to push the adjusting seat and the tongue seat to move horizontally. A return spring is installed between the adjusting seat and the tongue seat and the corresponding support base.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: During the terminal pressing process of the electrical connector, a tongue is inserted into one side of the electrical connector. The tongue, inserted into the interior of the electrical connector, can position and limit the electrical connector, and guide the inserted terminal, avoiding deviation during the terminal insertion process. On the other side of the electrical connector, an adjustment module is set to adjust the pressing depth of the terminal. One row of terminals of the electrical connector corresponds to dozens of adjustment modules. The adjacent step surfaces on the front side of the adjustment module are set with a 0.01mm discontinuity. Dozens of adjustment modules divide one row of terminals into dozens of segments. After the initial pressing of the terminal, by measuring the flat end of the terminal solder foot, the terminal area with out-of-specification flatness is found. The adjustment module corresponding to the area is vertically adjusted, thereby adjusting the pressing depth of the terminal in that area, so that the flatness of the terminal solder foot is adjusted to within the specification. After the adjustment is completed, the adjustment module is fixed on the back plate, which enables continuous pressing work until the flatness of the finished terminal is detected to be out of specification again.

[0012] This technical solution achieves precise adjustment of the flatness of slender products by setting up a segmented adjustment structure. During the adjustment of oversized areas, the dimensions of other areas are not affected, thereby improving production efficiency and the accuracy of finished products. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: like Figure 1-3As shown, the high-speed electrical connector terminal pressing adjustment device consists of three parts: a feeding structure, a positioning structure, and an adjustment structure. The feeding structure includes a horizontal flow channel 1 and feeding claws. The flow channel 1 consists of an upper plate and a lower plate. The gap between the upper and lower plates serves as the material passage for the electrical connector. Baffles are provided on both sides of the upper and lower plates in the width direction to limit and guide the electrical connector 2. The feeding claws move the electrical connector 2 into the pressing station.

[0019] The positioning structure and adjustment structure are respectively distributed on the front and rear sides of the flow channel 1, and correspond to the insertion surface and solder pin surface of the electrical connector 2 inside the flow channel 1. After the electrical connector 2 reaches the pressing station, the positioning structure inserts the connector to achieve positioning, and the adjustment structure adjusts the solder pins of the two rows of terminals inserted into the electrical connector.

[0020] The positioning structure includes a front bracket 3, a tongue seat 5 mounted on the top surface of the front bracket via a linear slide rail 4, and a tongue 6 mounted on the side of the tongue seat 5 near the flow channel. The adjustment structure includes a rear bracket 7, an adjustment seat 9 mounted on the top surface of the rear bracket 7 via a linear slide rail 8, and an adjustment assembly mounted on the side of the adjustment seat 9 near the flow channel. The tongue seat 5 and the adjustment seat 9 are respectively connected to a cam mechanism, which enables the tongue 6 and the adjustment assembly to move simultaneously toward the electrical connector 2, limiting the electrical connector 2 and adjusting the solder joints.

[0021] The cam mechanism includes a roller 10, a cam 11, a cylinder 12, and a support 13. The roller 10 is rotatably mounted on the side of the tongue seat 5 and the adjusting seat 9 away from the electrical connector / flow channel. The cam 11 is mounted on the corresponding support 13 via a vertical linear slide rail 14. The cam 11 is a wedge with an arc-shaped slope. The cylinder 12 is vertically positioned and fixedly connected to the cam 11. During the extension and retraction of the cylinder 12, the wedge slides upward and cooperates with the roller 10 to convert the vertical motion into horizontal motion. The roller 10 pushes the adjusting seat 9 and the tongue seat 5 to move horizontally toward the electrical connector. A return spring is installed between the adjusting seat 9 and the tongue seat 5 and the corresponding support 13. After adjustment is completed, the cylinder retracts, and the adjusting seat and the tongue seat return to their original positions under the spring tension.

[0022] The adjustment assembly includes a back plate 15, ten identical adjustment modules 16, and a mounting plate 17. The mounting plate 17 is installed on the front side of the back plate 15. The mounting plate 17 has a mounting groove on the surface facing the back plate 15. The top of the mounting groove is through. The ten adjustment modules 16 are inserted into the mounting groove in sequence, side by side and side by side. The sides, bottom surface, and back plate of the mounting groove limit the adjustment modules 16. The top of the adjustment module 16 extends out of the outside of the mounting groove. The protruding end is equipped with a screw as a handle to facilitate subsequent vertical adjustment. Multiple vertical adjustment slots 18 are provided on the back plate 15, and each adjustment module 16 corresponds to one adjustment slot 18. The back of each adjustment module 16 is fixed to the back plate 15 by screws passing through the adjustment slots 18. The lower half of the front of the adjustment module 16 is provided with a multi-level continuous stepped surface from top to bottom, and the difference between adjacent stepped surfaces is 0.01mm. The mounting plate 17 is provided with a horizontal slot 19 corresponding to the length of the electrical connector at the position corresponding to the terminal height of the electrical connector. The upper half of the front of the adjustment module 16 is provided with a scale corresponding to the multi-level stepped surface, and the corresponding scale displays the thickness of the stepped surface at the position corresponding to the horizontal slot 19.

[0023] During the pressing adjustment, the edge of the terminal strip passes through the horizontal groove 19 and makes contact with the adjusting component. When the flatness of the terminal solder foot in a certain area exceeds the specification, the corresponding adjusting module 16 is adjusted up and down. If the terminal in this area protrudes outward, the thicker step surface above the corresponding adjusting module 16 is adjusted to the horizontal groove, increasing the pressing amount during the pressing process and preventing the excess from being pressed back into the specification. Conversely, the thinner step surface below the corresponding adjusting module is adjusted to the horizontal groove. The adjustment amount is determined based on the measured vertical deviation and the scale of the adjusting module.

[0024] To ensure the precise positioning of the adjustment module during the adjustment process, a vertical protrusion 20 is provided on the back of the adjustment module, and a limiting groove 21 corresponding to and cooperating with the protrusion 20 is provided on the back plate 15, which further limits the positioning.
