Description

Switch life tester

Technical Field

The present utility model relates generally to the field of switch testing technology, and more particularly to a switch life tester.

Background

Currently, existing automotive P-speed switches require durability testing.

Fig. 1 to 4 show a switch life tester for testing a toggle switch 261 according to the present utility model, the switch life tester including a driving mechanism 100, a swivel base 110, and a key clamp 120. The drive mechanism 100 includes a fixed member 101 and a rotating member 102, the rotating member 102 being rotatable relative to the fixed member 101 about a rotation axis Z. The swivel base 110 is connected to the swivel member 102 such that the swivel base 110 can swivel relative to the fixed member 101 between an initial position and a testing position, the swivel base 110 being used for mounting a toggle switch 261 to be tested. The key clamp 120 is fixed with respect to the fixed member 101, and the key clamp 120 can toggle the toggle switch 261 during rotation of the rotary base 110 between the initial position and the testing position.

According to the switch life tester of the present utility model, the rotating member 102 drives the rotating base 110 to rotate relative to the fixed member 101 such that the toggle switch 261 mounted to the rotating base 110 rotates with the rotating base 110, thereby causing the key clamp 120 fixed relative to the fixed member 101 to toggle the toggle switch 261, thereby testing the toggle switch 261. Compared with the conventional mode of testing the toggle switch 261 by using the linear driving clamp, the actual working condition of the toggle switch 261 can be better simulated by using the human finger part, so that the service life of the toggle switch 261 is tested with higher accuracy.

In the actual testing process, the key clamp 120 and the toggle switch 261 are kept against each other, when the rotating base 110 rotates from the initial position to the testing position, the toggle switch 261 rotates between the closed position and the open position relative to the key clamp 120, and in contrast, the toggle switch 261 is toggled by the key clamp 120. By rotating the swivel base 110 instead of rotating the key clamps 120, the space occupied during testing can be reduced.

Referring to fig. 2, a toggle switch 261 mounted to the swivel base 110 coincides with the swivel axis Z with respect to the swivel axis of the swivel base 110. Therefore, when the rotating base 110 rotates, the toggle switch 261 rotates relative to the rotating base 110 under the abutting action of the case clamp, which is beneficial to preventing the case clamp from damaging the rotating shaft of the toggle switch 261, thereby affecting the life test precision of the toggle switch 261.

As an alternative, a deviation margin can be left between the toggle switch 261 mounted to the rotating base 110 relative to the rotation axis of the rotating base 110 and the rotation axis Z, and the deviation can be 0.05mm or less, so that the toggle switch 261 to be tested is convenient to mount and debug while the toggle switch 261 is ensured not to be damaged greatly.

Further, the driving mechanism 100 may be selected as a rotary cylinder or a motor, the fixed member 101 may be selected as a housing of the driving mechanism 100, and the rotary member 102 may be selected as an output shaft of the driving mechanism 100. Alternatively, the driving mechanism 100 may be a cam divider, the input shaft of the cam divider is connected to a driving component such as a motor, the fixing member 101 is a casing of the cam divider, the rotating member 102 is the output shaft of the cam divider, and the rotating member 102 performs reciprocating rotation according to the cam curve of the cam divider, so as to drive the rotating base 110 to reciprocate between the initial position and the testing position, and the testing efficiency is high.

Referring to fig. 1 and 3, the rotary base 110 has an L-shaped plate-like structure, and a bottom surface thereof is engaged with a top surface of the rotary member 102 and fixed to the rotary member 102 by a fastener 160. And the swivel base 110 is provided with reinforcing ribs 111, the reinforcing ribs 111 being connected to corners of the swivel base 110 to reinforce structural strength of the swivel base 110.

Further, the rotating base 110 is provided with a panel clamp 130, the panel clamp 130 is used for clamping a panel 260 provided with a toggle switch 261, and the panel 260 is clamped to the panel clamp 130. The provision of panel clamp 130 facilitates mounting of panel 260 and toggle switch 261 to swivel base 110.

In addition, the panel jig 130 is fixed to the side wall of the swivel base 110 by the fastener 160 so that the panel jig 130 is detachably mounted with the swivel base 110, facilitating development of the panel jig 130 suitable for testing of different switches. For example, the switch life tester according to the present utility model may be used for life testing of a P-range switch of an automobile, or may be used for testing a sunshade switch of an automobile, etc. by designing a different panel jig 130.

Optionally, the panel jig 130 is provided with a mounting groove 131 for mounting the panel 260, so that the mounting of the panel 260 is more stable. The mounting groove 131 is provided with a clamping groove 132 for matching with the panel 260, so that the panel 260 and the panel clamp 130 are clamped and fixed, and the panel 260 to be tested and the toggle switch 261 are convenient to assemble and disassemble.

Referring to fig. 1 to 4, the switch life tester according to the present utility model further includes a fixing frame 140 and a supporting bar 150. The fixing frame 140 is connected to the fixing member 101. The first end of the strut 150 is connected to the mount 140 and the second end of the strut 150 is connected to the key clamp 120. The arrangement of the mount 140 and the strut 150 allows the case clamp to be secured in a position that matches the toggle 261. The fixing frame 140 is mounted to the fixing member 101 by a fastener 160, and a top end of the fixing frame 140 is provided with a fixing block 141. The first end of the strut 150 penetrates through the fixing block 141, the strut 150 is provided with a nut 151, and the nut 151 is in threaded connection with the strut 150, so that the strut 150 and the fixing frame 140 can be detachably mounted. The second end of the strut 150 is inserted into the key clamp 120 and is screwed to the key clamp 120, so that the strut 150 is detachably mounted to the key clamp 120. In addition, the arrangement of the supporting rod 150 and the key clamp 120 is convenient for adjusting the interval between the key clamp 120 and the toggle switch 261.

Optionally, the supporting rod 150 is provided with at least two nuts 151, and the fixing block 141 is located between the nuts 151, so that the supporting rod 150 is adjustable along the length direction of the supporting rod 150 relative to the fixing frame 140, and further, the spacing between the key clamp 120 and the toggle switch 261 is convenient to adjust, and unnecessary damage to the switch rotating shaft caused by overlong or too short supporting rod 150 during testing of the toggle switch 261 is prevented.

Optionally, a rubber member is disposed in the key fixture 120, which is favorable for preventing the key fixture 120 from damaging the surface of the toggle switch 261, and can better increase the friction between the case fixture and the toggle switch 261.

Optionally, as shown in fig. 1, the key fixture 120 is provided with a groove, which is used for combining with the toggle switch 261 to simulate the actual working condition of the toggle switch 261 when the finger of the human body is toggling.
