Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a differential part disassembly device for an LRMDP socket connector. Background Art

[0002] The LRMDP connector is a standard connector used by the field replaceable module (LRM) of the integrated avionics system (IMA). It is suitable for SEM-D, SEM-E, and ASAAC modules, and can realize multiple signal transmissions such as RF, differential, optical, and power. The differential part of the LRMDP socket connector is connected by pressing the fisheye with the signal hole of the printed circuit board. When the differential part of the connector or the printed circuit board is damaged and needs to be repaired or replaced, the differential part needs to be disassembled.

[0003] At present, the known disassembly method is to use a tool to push out the differential part of the connector on the back of the printed circuit board. This method will cause the fisheye of the differential part to deform during the disassembly process, making it damaged and unable to be used again.

[0004] Therefore, it is urgent to design a LRMDP socket connector differential part disassembly device to solve the above-mentioned problem of fisheye deformation during the disassembly process. Summary of the invention

[0005] In order to solve the technical problem of fisheye deformation during disassembly mentioned in the background technology, a differential part disassembly device of an LRMDP socket connector is provided to solve the above problem.

[0006] To achieve the above-mentioned purpose, the specific technical scheme of the LRMDP socket connector differential part disassembly device of the present invention is as follows: A device for disassembling the differential part of an LRMDP socket connector, characterized in that it includes a lower frame for positioning the differential part, a lower orifice plate is installed on the lower frame, an upper frame is slidably connected to the lower frame, an upper orifice plate is installed on the upper frame, a first screw hole is opened on the lower frame, a shift bolt is screwed in the first screw hole, the shift bolt passes through the first screw hole and abuts against the upper frame, the shift bolt is rotated to make the upper orifice plate slide relative to the lower orifice plate, so that the holes of the upper orifice plate and the holes of the lower orifice plate are staggered and clamp the thin axis of the differential contact, and the lower frame is driven away from the printed circuit board to disassemble the differential part.

[0007] Furthermore, a protrusion is provided on the lower frame, and a first long through hole is provided on the upper frame. The cross-sectional area of ​​the first long through hole is larger than that of the protrusion. The protrusion cooperates with the first long through hole to enable the upper frame and the lower frame to be slidably connected.

[0008] Furthermore, the length of the first long through hole in the sliding direction is greater than the length of the protruding block in the sliding direction, and the length of the first long through hole in the vertical sliding direction is adapted to the length of the protruding block in the vertical sliding direction to limit the sliding direction of the upper frame and the lower frame.

[0009] Furthermore, a limiting bolt is screwed onto the protruding block, and the cross-sectional area of ​​the end of the limiting bolt is larger than the cross-sectional area of ​​the first long through hole, thereby limiting the upper frame.

[0010] Furthermore, the lower hole plate and the lower frame are screwed together by a first bolt, and the upper hole plate and the upper frame are screwed together by a second bolt. A first avoidance hole is provided on the lower hole plate to avoid the second bolt when the upper frame and the lower frame slide, and a second avoidance hole is provided on the upper hole plate to avoid the first bolt when the upper frame and the lower frame slide.

[0011] Furthermore, the holes formed on the upper orifice plate and the lower orifice plate match the thin shafts of the differential contact pieces.

[0012] Furthermore, it also includes a base plate, which is in the shape of a hollow frame. The shape of the base plate matches the shape of the differential part, so that the base plate abuts against the printed circuit board. A second screw hole is opened on the lower frame, and a pull-out screw is screwed into the second screw hole. The end of the screw rod of the pull-out screw abuts against the base plate. When the pull-out screw is rotated, the pull-out screw abuts against the base plate and drives the lower frame away from the printed circuit board.

[0013] Furthermore, the second screw holes are centrally symmetrically arranged at the edge of the lower frame.

[0014] Furthermore, a handle is installed on the lower frame.

[0015] Furthermore, the displacement bolts are arranged on opposite sides of the lower frame.

[0016] The LRMDP socket connector differential part disassembly device of the present invention has the following advantages: The present invention uses an upper hole plate and a lower hole plate to alternately clamp the differential contact piece to pull out the differential part, so that the fish eye does not generate new deformation during the disassembly process.

[0017] The invention provides a pulling screw and realizes the disassembly of the differential part in a manner that the pulling screw presses against the bottom plate and then reacts on the lower frame, so that the lower frame moves away from the printed board, and no new damage is caused to the printed board during the disassembly process.

[0018] The present invention is easy to operate, saves time and effort, and locking screws are arranged on opposite sides of the lower frame, so that one side of the two sides can be selected for locking, which is convenient for personnel to operate. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the lower orifice plate 201 and the upper orifice plate 301 are stacked and located at the thin shaft 103, and the displacement bolt 4 is rotated to displace the upper orifice plate 301, so that the holes of the lower orifice plate 201 and the holes of the upper orifice plate 301 are staggered to clamp the thin shaft 103 of the differential contact 102, so that the lower orifice plate 201 and the upper orifice plate 301 are abutted against the differential contact 102, and the operator operates the lower frame 2 away from the printed circuit board to disassemble the differential part 1.

[0029] As a preferred example, Figure 3 and Figure 4 As shown, a protruding block 203 is provided on the lower frame 2, and a first long through hole 302 is provided on the upper frame 3. The cross-sectional area of ​​the first long through hole 302 is larger than the area of ​​the protruding block 203. The protruding block 203 cooperates with the first long through hole 302, so that the protruding block 203 can move in the first long through hole 302, so that the upper frame 3 and the lower frame 2 are slidably connected.

Specifically, the base plate 5 is located between the printed circuit board and the pull-out screw 6, so as to protect the printed circuit board. The material of the base plate 5 is preferably a rigid material, such as an iron plate or a steel plate.

[0035] Preferably, the second screw holes 207 are centrally symmetrically arranged at the edge of the lower frame 2, so that each extraction screw 6 can evenly separate the differential portion 1 from the printed circuit board.

[0036] Preferably, a handle 7 is installed on the lower frame 2 to facilitate the operator to install and remove and assist in pulling out.
