Description

Technical Field

[0001] This utility model relates to the field of PCB technology, specifically to a multilayer PCB stator with integrated phase-to-phase resistance monitoring points. Background Technology

[0002] In the field of multilayer PCB stator manufacturing, traditional phase-to-phase resistance monitoring points are usually fixed by welding or external test fixtures: welding test points make maintenance difficult, and replacement requires desoldering, which can easily damage the PCB circuit; external fixtures have low positioning accuracy and unstable contact pressure, which affects the accuracy of resistance measurement. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a multilayer PCB stator with integrated interphase resistance monitoring points, comprising:

[0004] PCB board;

[0005] Two limiting components are equally spaced within the PCB board and can elastically rise or fall along the thickness direction of the PCB board, respectively.

[0006] Two test components are detachably mounted on the PCB board at equal intervals and respectively mounted on two limiting components. The limiting components elastically rise in the vertical direction to push the test components against the PCB board, thereby fixing the test components.

[0007] Preferably, the PCB board has two fixing slots, which are equally spaced.

[0008] Preferably, the limiting component includes:

[0009] A positioning plate, wherein the positioning plate is disposed at the top of the fixing groove;

[0010] A through hole is provided in the middle of the positioning plate and is provided to penetrate through the thickness direction of the positioning plate;

[0011] Two positioning slots are disposed opposite to each other on the positioning plate and are connected to the through hole;

[0012] Two limiting grooves are respectively disposed opposite to each other on the bottom of the positioning plate;

[0013] An elastic element is disposed within the fixing groove;

[0014] The slide plate is slidably disposed within the fixed groove and connected to the elastic element.

[0015] Preferably, the two positioning grooves and the two limiting grooves are arranged in a cross shape.

[0016] Preferably, the outer peripheral surface of the slide plate is in contact with the inner sidewall of the fixing groove.

[0017] Preferably, the test component includes:

[0018] Fixing plate;

[0019] Two extension plates are respectively disposed opposite to each other on the outer peripheral surface of the fixed plate;

[0020] Two limiting blocks are respectively disposed on the two extension plates;

[0021] A test probe, which is vertically mounted on the fixed plate.

[0022] Preferably, the two extension plates correspond to the two positioning slots respectively.

[0023] Preferably, the two limiting blocks correspond to the two limiting grooves respectively.

[0024] The above-described solution of this utility model has at least the following beneficial effects:

[0025] When it is necessary to install the test component, insert the test component onto the PCB board and apply pressure to the limiting component to make the limiting component elastically descend. Then rotate the test component 90° or 180° to make the test component correspond to the installation position inside the PCB board. When the test component is rotated to the appropriate angle, the limiting component elastically rises along the thickness direction of the PCB, pushing the test component upward. The test component is pressed tightly inside the PCB board to achieve self-adaptive clamping and fixing.

[0026] The test components can be installed or removed by simply rotating and pressing, without the need for external tools. The limit components can be elastically lifted to adapt to the flatness of the PCB board, eliminating poor contact and other issues.

[0045] The multilayer PCB stator with integrated phase-to-phase resistance monitoring points according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0046] Please see Figures 1-5In this embodiment, the device includes: a PCB board 1; two limiting components 2, which are equally spaced within the PCB board 1 and can be elastically raised or lowered along the thickness direction of the PCB board 1; and two test components 3, which are detachably and equally spaced on the PCB board 1 and respectively on the two limiting components 2. The limiting components 2 elastically rise along the vertical direction to press the test components 3 against the inside of the PCB board 1, thereby fixing the test components 3.

[0047] When test component 3 needs to be installed, insert test component 3 into PCB board 1, and at the same time apply pressure to limit component 2 so that limit component 2 elastically descends. Then rotate test component 3 by 90° or 180° so that test component 3 corresponds to the installation position inside PCB board 1. When test component 3 is rotated to the appropriate angle, limit component 2 elastically rises along the PCB thickness direction and pushes test component 3 upward. Test component 3 is pressed tightly inside PCB board 1 to achieve self-adaptive clamping and fixing.

[0048] The test component 3 can be installed or removed by simply rotating and pressing it, without the need for external tools. The limit component 2 can be elastically lifted to adapt to the flatness of the PCB board 1, eliminating poor contact and other issues.

[0049] In this embodiment, the PCB board 1 is provided with two fixing slots 101, which are equally spaced. The limiting component 2 includes: a positioning plate 201, which is disposed at the top of the fixing slot 101; a through hole 202, which is disposed in the middle of the positioning plate 201 and is disposed through the thickness direction of the positioning plate 201; two positioning slots 203, which are disposed opposite to each other on the positioning plate 201 and are connected to the through hole 202; two limiting slots 204, which are respectively disposed opposite to each other at the bottom of the positioning plate 201; an elastic element 205, which is disposed in the fixing slot 101; and a sliding plate 206, which is slidably disposed in the fixing slot 101 and connected to the elastic element 205.

[0050] The aforementioned elastic element 205 can be a compression spring, airbag, or other elastic object. The test component 3 is inserted into the fixing groove 101 through the through hole 202 and two positioning grooves 203. At the same time, the test component 3 applies pressure to the slide plate 206 so that the slide plate 206 compresses the elastic element 205. Then, the test component 3 rotates 180° so that the test component 3 corresponds to the limiting groove 204. Then, the elastic element 205 releases pressure and rises elastically to push the slide plate 206 to fix the test component 3 in the limiting groove 204, thereby completing the installation of the limiting component 2.

[0051] In this embodiment, the two positioning slots 203 and the two limiting slots 204 are arranged in a cross shape; the cross shape allows the test component 3 to be blindly inserted into the fixing slot 101 from the positioning slot 203, and can be installed with the limiting slot 204 by rotating 180°, thereby ensuring the rapid installation of the test component 3.

[0052] In this embodiment, the outer peripheral surface of the slide plate 206 is in contact with the inner sidewall of the fixing groove 101; the inner wall of the fixing groove 101 is in close contact with the slide plate 206, thereby restricting the positioning plate 201 to move only vertically and avoiding poor contact caused by the tilt of the test probe 304.

[0053] In this embodiment, the test assembly 3 includes: a fixed plate 301; two extension plates 302, which are respectively disposed opposite to each other on the outer peripheral surface of the fixed plate 301; two limiting blocks 303, which are respectively disposed on the two extension plates 302; a test probe 304, which is vertically disposed on the fixed plate 301; the two extension plates 302 are respectively corresponding to the two positioning grooves 203; and the two limiting blocks 303 are respectively corresponding to the two limiting grooves 204.

[0054] The extension plate 302 is inserted into the positioning groove 203, forcing the test component 3 to slide horizontally along a single path. Then, the test probe 304 is rotated, while the fixing plate 301 applies pressure to the limiting component 2, causing the limiting component 2 to elastically descend. When the limiting block 303 rotates to directly below the limiting groove 204, the compressed limiting component 2 automatically and elastically rises, fixing the limiting block 303 in the limiting groove 204, thus completing the installation of the test component 3.
