The fixing part 7 comprises a connecting terminal used for being connected and conducted with a product to be detected on one side close to the product to be detected; the connection terminal of the switch member 4 is exposed from the bottom of the case 3; the switch piece 4 is configured to be connected and conducted with the product to be tested when the moving part 8 moves to the second station; when the moving part 8 moves to the first station, the connecting terminal is disconnected and separated from the product to be tested.
It can be understood that the fixed part 7 of the switch member 4 is welded with the circuit board 2 by a pin, and the moving part 8 of the switch member 4 is sleeved on the periphery of the fixed part 7; the moving portion 8 is movable up and down in the axial direction of the fixed portion 7 with respect to the fixed portion 7; when the moving part 8 slides downwards to the first station, the connecting terminal of the switch member 4 is in a loose state; when the moving part 8 slides upward and returns to the second position, the connection terminal of the switch member 4 is in a clamped state. Through the arrangement, the linkage plate drives the moving part 8 of the switch piece 4 to move upwards, so that the connecting terminal of the switch piece 4 can clamp the terminal of the product to be tested. When the exposed part 1 moves downwards under the action of an acting force, the linkage plate can drive the moving part 8 of the switch piece 4 to move downwards to the first station, so that the connecting terminal on the switch piece 4 is loosened, and the plugging mechanism can be separated from a product to be tested.
In a specific embodiment, the linkage plate includes two exposed portions 1 symmetrically disposed on two opposite sides of the housing 3, and the exposed portions 1 and the plate portion 9 are perpendicular to each other. Through the arrangement, when the linkage plate is stressed to move, the plate body part 9 can be kept horizontal, so that the plurality of switch pieces 4 are driven to move stably, the effect of plugging and unplugging simultaneously is achieved, the exposed part 1 and the plate body part 9 are perpendicular to each other, the linkage plate is stressed uniformly, and the phenomenon that the plate body is stressed unevenly and inclines is avoided.
In the present embodiment, further, the housing 3 includes a top wall and a side wall fixed in combination with the top wall; openings are formed on two opposite side walls of the shell 3; the exposed part 1 extends from the opening. The advantage is that the exposed part 1 can move in the area limited by the opening of the shell 3, the moving path of the exposed part does not exceed the opening of the shell 3, the size of the shell 3 is not increased additionally, and the whole structure of the invention is more compact. It should be noted that due to the elastic member 6, the exposed portion 1 is normally located at the upper position of the housing 3, i.e. the initial position of the exposed portion 1 is located at the top end of the moving path.
Furthermore, two opposite sides of the top wall are respectively formed with a limiting structure; the limiting structure comprises two limiting parts 10 which are symmetrically arranged at two sides of the exposed part 1 along the moving direction of the exposed part 1. The limiting part 10 plays a limiting role to prevent the exposed part 1 from deviating from the movement path under the action of external force, so that the linkage plate is ensured to be stably lifted.
In a specific embodiment, the housing 3 comprises at least two elastic pieces 6 for providing acting force for the linkage plate; the two elastic pieces 6 are symmetrically arranged relative to the plate body part 9, the elastic pieces 6 are positioned between the plate body part 9 and the side wall of the shell 3, and the acting force direction of the elastic pieces 6 is perpendicular to the plate body part 9. When the linkage plate is under the effect of external force and descends to a certain height, the switch piece 4 is reliably connected with a product to be detected, when the switch piece 4 and the product to be detected need to be separated, in order to facilitate operation, extra acting force does not need to be applied to the exposed part 1, the restoring force of the elastic piece 6 can be used for enabling the linkage plate to drive the moving part 8 of the switch piece 4 to move upwards for resetting, the switch piece 4 is in a disconnected state, the connecting terminal of the switch piece is not connected with the terminal of the product to be detected, and the effect of separating the switch piece 4 and the product to be detected is achieved.
In this embodiment, a groove is formed in the housing 3 for accommodating the elastic member 6, the elastic member 6 is a plate spring, the plate spring includes two feet located on the bottom wall of the groove and an arc portion located between the two feet, and the top end of the arc portion abuts against the plate body portion 9. The plate springs are arranged on the two sides of the shell 3, so that even elastic force is applied to the two sides of the linkage plate after the linkage plate is free from external force, the linkage plate can be horizontally lifted, the moving parts 8 of the switch pieces 4 are driven to synchronously lift, and the effect of simultaneous disconnection is achieved. The elastic part 6 adopts a plate spring, and has the advantages that the assembly in the groove is easier, and the stress of the linkage plate is uniform.
In a specific embodiment, the fixing portion 7 includes a connection terminal for connecting and communicating with a product to be tested, the switch element 4 is fixed to the linkage plate through the assembly plate 5, and the assembly plate 5 and the linkage plate both include a hollow portion for exposing the connection terminal. The linkage plate is provided with hollows so as to avoid a connecting space for the connecting terminal of the switch part 4; the hollow-out part arranged on the assembling plate 5 is used for ensuring that the switch part 4 is connected with the circuit board 2 and avoiding the connecting terminal.
For convenience of operation, the top wall surface of the exposed portion 1 is located above the top wall surface of the stopper portion 10. The part of the exposed part 1 higher than the limiting part 10 is convenient for the hand of an operator to directly apply acting force to the exposed part 1 without being influenced by the limiting part 10, and the distance of the exposed part 1 higher than the limiting part 10 can be the maximum displacement of the linkage plate.
In addition, in an alternative embodiment, the side wall is formed with a connecting portion extending outward, and the connecting portion includes a fixing hole. The bolt is convenient to penetrate through the fixing hole in the connecting part, the plugging structure is matched with other external equipment after being fixedly connected, and the application range is enlarged.
In a specific implementation process, taking acceleration detection as an example, taking the plugging mechanism above an accelerometer to be tested, simultaneously pressing the exposed parts 1 on two sides of the linkage plate by thumb of left and right hands until the positions are reached, keeping the plugging mechanism still, positioning the moving part 8 of the switch part 4 at a first station at the moment, positioning the switch part 4 at a disconnected state, positioning the connecting terminals of the switch part 4 at a loosened state, aligning each switch part 4 on the plugging mechanism with the accelerometer to be tested respectively and press-fitting the switch part 4 on the accelerometer to ensure that the terminals on the accelerometer are positioned between the connecting terminals in the loosened state of the switch part 4, then loosening the thumb of the left and right hands, moving the linkage plate upwards under the elasticity of a plate spring and driving the moving part 8 of the switch part 4 to move upwards and recover to an initial position, namely a second station, and clamping the terminals of the accelerometer to be tested by the connecting terminals of the switch part 4 at the moment, the switch 4 is in a conducting state, and reliable connection between the switch 4 and the accelerometer to be tested is completed. After the test is finished, the exposed parts 1 on the two sides of the linkage plate are pressed down by the thumbs of the left hand and the right hand at the same time, and then the switch part 4 of the plugging mechanism can be separated from the accelerometer.
In summary, the invention ensures reliable connection between the switch piece and the product to be tested by driving the moving part of the switch piece to move through the linkage plate, which is convenient for collecting subsequent test signals, and the plugging mechanism can simultaneously control the on-off of a plurality of switch pieces and the product to be tested, thereby improving the plugging efficiency and saving the operation time.
