Description

Technical Field

[0001] This invention relates to the field of connector processing technology, specifically to a pin-removing fixture for processing multi-pin connectors. Background Technology

[0002] In the fields of PCB and PCBA product circuit design and connector processing, the material selection and matching method is to match the component model with the exclusive structural design. Technicians need to match the corresponding through hole, positioning tooling and processing fixture structure according to the number of connector pins, spacing and installation specifications. For multi-pin connectors, different pin numbers and different thickness specifications of connector materials all require the independent development of exclusive positioning molds and pin removal tooling. Currently, most conventional pin removal fixtures on the market adopt an integrated fixed cavity structure. One set of fixtures can only be used to fit a single model and size of power strip. The matching black bakelite, fiberglass, and aluminum alloy positioning plates need to be cut, drawn, and processed separately according to the material specifications. For each new power strip material model, a brand new CAD two-dimensional drawing, three-dimensional model, and special processing fixture must be developed simultaneously. Material selection, tooling design, and mold processing are completely linked. However, since different pin counts and thicknesses of power strips cannot share a single set of pin removal fixtures, whenever a new power strip material model is added, designers need to redraw a complete set of two-dimensional planar drawings and three-dimensional CAD drawings. For example, they need to design corresponding through holes according to the number of pins on the power strip, and simultaneously complete the structural design, machining, and sample verification of the dedicated fixture, which lengthens the overall R&D cycle of the PCBA project. Moreover, the integrated fixed cavity structure can only be adapted to a fixed pin layout. If the pin layout of the power strip is slightly adjusted, the entire fixture is scrapped and cannot be reused, resulting in material waste. Summary of the Invention

[0003] The purpose of this invention is to provide a pin removal fixture for multi-pin connector processing, which is compatible with multiple pin arrangements and various thicknesses of connectors, enabling the use of common material models and effectively reducing material waste, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pin-removing fixture for multi-pin connector processing, comprising a base plate, a support structure and a base fixed on the upper surface of the base plate, a handle mounted on the support structure, a movable plate fixed at the movable end of the handle, a guide mechanism mounted on the movable plate, the two ends of the guide mechanism being respectively connected to the base plate and the support structure, a pressure plate fixed on the lower surface of the movable plate, and a boss fixed on the lower surface of the pressure plate; The base is located directly below the pressure plate, and the base is provided with a bearing groove for bearing the pin header to be removed. The position of the boss matches the position where the pin header pins are to be removed.

[0005] Preferably, a through hole is provided at the bottom of the bearing groove, and a material discharge hole is provided on the bottom plate. The material discharge hole, the through hole, and the boss are located on the same horizontal plane and are used to guide the pins to be pulled out of the pin assembly for material discharge.

[0007] Preferably, positioning posts are fixed at both ends of the lower surface of the base, and positioning holes are provided on the base plate. When the base is connected to the base plate, the positioning posts are located in the positioning holes.

[0008] Preferably, a notch is provided on one side of the bearing groove for material retrieval, and a foolproof groove is provided on the bearing groove, the shape of which matches the shape of the pin header to be removed.

[0009] Preferably, the boss and the pressure plate are integrally formed, the boss and the pressure plate are aluminum alloy plates, and the corner at the lower end of the boss is an arc corner.

[0010] Preferably, a protruding post is fixed on the upper surface of the pressure plate, and a nut is threaded through the upper end of the protruding post through the movable plate. A through hole is provided on the movable plate to allow the protruding post to pass through the movable plate.

[0011] Preferably, the lower end of the protruding post has an integrally formed external thread section on its outer wall, and the upper surface of the pressure plate has a threaded hole, with the lower end of the protruding post threadedly connected to the threaded hole.

[0012] Preferably, the support structure includes a mounting plate, with vertical plates fixed at both ends of the mounting plate, the lower end of the vertical plate being fixed to the upper surface of the base plate, the vertical plates and the mounting plate forming a U-shaped structure, the mounting end of the handle being fixed to one side of the mounting plate, the movable plate being located between the two vertical plates, and the guide mechanism being located between the mounting plate and the base plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a base to support the pins to be removed and a pressure structure consisting of a boss and a pressure plate. It is compatible with multi-pin connector base materials of various thicknesses. Only the pressure plate with the corresponding boss needs to be replaced according to the location of the excess pins to be removed. There is no need to re-process a whole set of special black bakelite and aluminum alloy fixtures for different pin arrangements and different specifications of connectors. This enables the use of common materials and avoids material waste caused by one-to-one exclusive materials and special tooling.

[0015] 2. The base plate, support structure, and handle of this invention are standardized and universal structures.

This reduces the design workload of new materials and a complete set of fixture structures, and shortens the material selection and tooling development cycle of the new product PCBA.

[0016] 3. The present invention features a material drop hole, a through hole, and a boss located on the same horizontal plane. In use, the base plate is placed on the collection box, and the material drop hole and the through hole form a material guide channel, allowing the pins removed by the boss to fall into the collection box through the material guide channel, thereby improving the convenience of collecting the removed pins.

[0017] 4. The present invention makes the pressure plate and the movable plate detachable, which facilitates the replacement of the pressure plate with different boss positions according to the pin removal requirements of different multi-pin connectors, thereby improving the convenience of pressure plate replacement.

[0018] 5. The present invention features a detachable connection between the base and the base plate, which facilitates the replacement of the base with different shaped support grooves according to the pin removal requirements of different multi-pin power strips, thus adapting to more power strip pin removal applications and improving the versatility of the clamp.

[0027] Please see Figure 1-5 This invention provides a technical solution: a pin-removing fixture for multi-pin connector processing, comprising a base plate 1, a support structure 2 and a base 3 fixed on the upper surface of the base plate 1, a handle 4 mounted on the support structure 2, a moving plate 5 fixed to the moving end of the handle 4, a guide mechanism 6 mounted on the moving plate 5, the two ends of the guide mechanism 6 being connected to the base plate 1 and the support structure 2 respectively, a pressure plate 7 fixed on the lower surface of the moving plate 5, and a boss 8 fixed on the lower surface of the pressure plate 7; the base 3 is located directly below the pressure plate 7, and a bearing is provided on the base 3. The groove 9 is used to support the pins to be removed from the connector. The position of the boss 8 matches the position of the pins to be removed from the connector, so that the boss 8 is directly above the pins to be removed. By pushing the handle on the handle 4, the moving plate 5 is driven to move downward, so that the moving plate 5 drives the pressure plate 7 to move downward and contact the pins to be removed on the base 3. The boss 8 is used to push the pins to be removed from the connector, so that the removed pins are removed from the connector. It is suitable for removing pins from connectors of the same shape but different thicknesses. The pressure plate 7 with the corresponding boss 8 can be replaced according to the position of the excess pins to be removed.

[0028] To facilitate the collection of removed pins, a through hole 10 is provided at the bottom of the bearing groove 9, and a discharge hole 11 is provided on the base plate 1. The discharge hole 11, the through hole 10, and the boss 8 are located on the same horizontal plane, which is used to guide the pins to be removed from the pin rack to discharge. The discharge hole 11 and the through hole 10 form a guide channel, so that the pins removed by the boss 8 fall into the collection box through the guide channel, improving the convenience of collecting removed pins.

[0029] To accommodate power strips of different shapes, mounting holes 12 are provided at both ends of the base 3. The base 3 is connected to the base plate 1 by bolts passing through the mounting holes 12, making the base 3 and the base plate 1 detachably connected. This facilitates the replacement of the base 3 with different shaped bearing grooves 9 according to the pin removal requirements of different multi-pin power strips, thereby improving the versatility of the fixture.

[0030] To improve the installation accuracy of the base 3, positioning posts are fixed at both ends of the lower surface of the base 3, and positioning holes are opened on the base plate 1. When the base 3 is connected to the base plate 1, the positioning posts are located in the positioning holes, which can quickly and initially position the base 3 and the base plate 1. Then, bolts are used to fix the base 3 and the base plate 1, increasing the firmness of the connection between the base 3 and the base plate 1.

[0031] Furthermore, a notch 13 is provided on one side of the bearing groove 9 for material retrieval. An anti-fooling groove is provided on the bearing groove 9. The shape of the anti-fooling groove matches the shape of the pin connector to be removed. The bearing groove 9 is not shown in the figure. According to the characteristics of different multi-pin connector shapes, an anti-fooling groove is provided on the bearing groove 9. The anti-fooling groove ensures that the connector can only be placed in the bearing groove 9 in an oriented manner, avoiding the connector from being placed in reverse.

[0032] Specifically, the boss 8 and the pressure plate 7 are integrally formed, the boss 8 and the pressure plate 7 are aluminum alloy plates, and the corner at the lower end of the boss 8 is an arc corner to prevent the corner of the boss 8 from scratching the selected product.

[0033] To facilitate the connection between the pressure plate 7 and the movable plate 5, a protrusion 14 is fixed on the upper surface of the pressure plate 7. The upper end of the protrusion 14 passes through the movable plate 5 and is threaded with a nut 15. A through hole 16 is provided on the movable plate 5 to allow the protrusion 14 to pass through the movable plate 5, so that the pressure plate 7 and the movable plate 5 can be detached. This makes it easy to replace the pressure plate 7 with different protrusion 8 positions according to the pin removal requirements of different multi-pin connectors, thus improving the convenience of pressure plate 7 replacement.

[0034] Furthermore, the lower end of the protruding post 14 has an integrally formed external thread section on its outer wall, and the upper surface of the pressure plate 7 has a threaded hole. The lower end of the protruding post 14 is threaded into the threaded hole, so that the protruding post 14 and the pressure plate 7 are detachably connected, allowing the protruding post 14 to be adapted to different pressure plates 7 for installation and use, thereby reducing the manufacturing cost of the pressure plate 7.

[0035] In this embodiment, the support structure 2 includes a mounting plate 21, with vertical plates 22 fixed at both ends of the mounting plate 21. The lower end of the vertical plate 22 is fixed to the upper surface of the base plate 1. The vertical plate 22 and the mounting plate 21 form a U-shaped structure. The mounting end of the handle 4 is fixed to one side of the mounting plate 21. The movable plate 5 is located between the two vertical plates 22. The guide mechanism 6 is located between the mounting plate 21 and the base plate 1. The support structure 2 provides a mounting platform for the handle 4, and the handle 4 provides support for the movable plate 5, making it easy to use the handle on the handle 4 to drive the movable plate 5 to rise or fall.

[0036] Furthermore, the guiding mechanism 6 includes a guide rod 61, and the movable plate 5 is slidably connected to the guide rod 61. The two ends of the guide rod 61 are respectively fixed to the surface of the mounting plate 21 and the upper surface of the base plate 1. The movable plate 5 is provided with a sliding hole 62, so that the movable plate 5 can move in a directional manner along the guide rod 61, ensuring the accuracy of the downward or upward movement of the movable plate 5.
