Description

Micro-gap switch OP value detection conversion device

Technical Field

The utility model relates to the technical field of micro-switch detection devices, in particular to a micro-switch OP value detection conversion device.

Background

The micro switch is a device with a tiny contact interval and a quick action mechanism; the switch can be operated by utilizing a preset stroke and a preset force. Because the contact spacing of the switch is relatively small, the micro switch is called a sensitive switch. In the prior art, a micro switch generally comprises a driving rod, a switch shell, a terminal or pin, a movable piece, a static contact or a static contact, a movable contact or a movable contact and other parts. The driving rod can transmit external force to the internal spring structure so as to push the movable contact to realize the switching action; the interval between the stationary contact and the movable contact is generally referred to as contact interval, i.e. OP value; the OP is Operating Position, i.e. the action position is abbreviated as "action position". The OP value is the effective working distance of the micro switch, so the design interval of the contact is usually the main design goal of the micro switch. When the micro switch is in use, the minimum contact interval is required to be selected after meeting the design requirement, and the standard of the contact interval is 0.5mm. In addition, for the similar micro switch structure, the smaller the contact point interval is, the smaller the MD, namely the difference distance is; i.e. the higher its sensitivity, the longer its mechanical lifetime.

In addition, toggle switches; is a manual control switch. It is mainly used for on-off control of AC/DC power supply circuit, but can be used in circuit of several kilohertz or up to one megahertz. The toggle switch has the characteristics of small volume, convenient operation and the like, and is a switch commonly used in electronic equipment. Common button switches include a sleeve, an inner front ring, a handle, a push rod, and the like. The push rod is displaced by pulling the handle, so that the function of a switch is realized. The button switch also comprises an annular sealing ring, the inner ring of which is directly in interference fit with the push rod, so that the sealing between the annular sealing ring and the push rod is realized.

Furthermore, before the micro switch leaves the factory, the contact interval of the micro switch is usually detected, that is, the OP value of the micro switch is detected, so as to determine whether the micro switch meets the use requirement. At present, the detection of the OP value of the micro switch is usually carried out by using a measuring tool matched with an operator; therefore, an operator needs to hold the measuring tool with one hand and hold the micro switch with the other hand, and then the data on the measuring tool is read, so that the purpose of detection is achieved. Thus making the operation cumbersome and inefficient. Especially for mass production, the mode of detecting the OP value seriously affects the production efficiency of the micro switch.

Based on this, chinese patent CN218380849U discloses a micro-gap switch OP value detector, and it is including the base, set up detection piece, detection platform, the suggestion module on the base, and detection piece constitutes sliding fit with the base, is provided with the contact piece on the detection platform, and contact piece constitutes electric connection with the suggestion module, one side of detection piece is including the contact fitting surface that is the echelonment profile, the contact fitting surface is including upper limit value detection section, lower limit value detection section respectively along the slip direction of detection piece, the suggestion module is including response module and two suggestion modules, and two suggestion modules can be respectively when upper limit value detection, lower limit value detection are qualified and are reminded. The micro-switch OP value detector can rapidly and accurately distinguish whether the micro-switch OP has an upper limit value fault or a lower limit value fault; so as to meet the requirement that the micro switch avoids manual measurement and is suitable for mass production detection.

However, the above disclosed micro switch OP value detector has a technical problem of insufficient versatility. In particular, in the production practice of microswitches, the same type of microswitches often have two different types which are symmetrical to each other due to the requirements of different assembly occasions; the two symmetrical microswitches have the same functions of high-low switching except that the functional positions of the pins are different. At this time, one of the two kinds of micro switches is positioned at the left side and the other is positioned at the right side. The micro switch of each model can be off line only by performing hundred percent detection before leaving the factory; on the premise that the overall structures of the microswitches are similar, cost waste can be caused if one set of OP value detection device is independently developed for each type of the microswitches.

Referring to fig. 1 to 8, the micro switch OP value detecting and converting device of the present utility model includes: base 1, spacing tool 2, measurement tool 3, measurement contact 4 and button switch 5; one end above the base 1 is provided with the limiting jig 2; the other end above the base 1 is provided with the measuring jig 3; the three measuring contacts 4 are arranged on the other side surface of the limiting jig 2 relative to the measuring jig 3; the button switch 5 has two pin sets 501 and a button handle 502; each pin group 501 is provided with three pins 501a; the three pins 501a are correspondingly and electrically connected with the three measuring contacts 4; when the knob 502 is operated, the different pin groups 501 are switched to conduct with the measuring contact 5.

Specifically, in a specific embodiment, the micro switch 6 for measuring the OP value has two structures symmetrical to each other; each of the microswitches 6 is provided with a microswitch button 601 and three connecting pins 602; the micro-switch button 601 can switch the connection states of the three connection pins 602 and the external circuit. For example, when the micro switch button 601 is turned on, the connection state between the COM pin or NC pin and the common terminal NO pin may be switched. The micro switch 6 is connected with the limiting jig 2 during measurement; at this time, the three connection pins 602 are respectively and electrically connected to one of the measurement contacts 4; the micro-switch button 601 is movably connected with the measuring jig 3. The measuring jig 3 has a high-level side measuring section 301 and a low-level measuring section 302; when the micro-switch button 601 is pressed, the high-level measuring unit 301 and the low-level measuring unit 302 measure the high-level and low-level states of the micro-switch button 601, respectively. The OP value of the micro switch 6 is the result of measurement. If the symmetrical micro-switches 6 need to be replaced in the limiting jig 2, only the other micro-switch 6 needs to be placed on the limiting jig 2; the knob handle 502 arranged on the knob switch 5 is shifted again; to switch different ones of the pin sets 501 into electrical communication with the measurement contacts 4; at this time, although the micro switch 6 in the later replacement has the opposite connection pins 602, the micro switch OP detection and conversion device of the present utility model can still work normally without changing its hardware design, so that it has good versatility.

More specifically, when the knob handle 502 provided to the knob switch 5 is in a closed state, current flows from one of the pin groups 501 of the knob switch 5; then, the flow passes through the COM pin and NC pin of the micro switch 6 and then flows out. When another micro switch is replaced on the limiting jig 2; at this time, the knob handle of the knob switch 5 may be turned on, and the current may flow in from the other pin group 501 of the knob switch 5 and flow out via the COM pin and NC pin of the other micro switch. It can be seen that the changed microswitch 6 needs to have a different structure, but the current always flows from the COM pin to the NC pin, so that the versatility of measurement can be ensured.

Further, an installation clamping groove 201 is formed in the limiting jig 2; the two mounting clamping grooves 201 are adjacently arranged on the limiting jig 2. The microswitch 6 has a mounting connection 603; the two mounting connection parts 603 are connected. Each of the mounting connection portions 603 is movably connected with one of the mounting clamping grooves 201. Specifically, when the limit jig 2 needs to fix the micro switch 6 thereon, the mounting connection portion 603 provided on the micro switch 6 may be connected by matching with the mounting clamping slot 201; thereby, the micro switch 6 can be limited and placed. In addition, when the micro switch 6 is placed in a limited position, the three connecting pins 602 provided on the micro switch may be correspondingly connected with the three measuring contacts 4 in a matching manner.

Further, the measuring jig 3 has a cylindrical structure, the end of the measuring jig 3 is provided with a high-level and low-level structure, the high-level measuring part 301 has a lower-level structure, and the low-level measuring part 302 has a higher-level structure; the two-step structure sequentially measures different use states of the micro switch button 601, so that the measurement of the OP value can be realized. More specifically, the measuring tool 3 may rotate around its axis along the upper side of the base 1; thereby, the switching between the high-level measuring section 301 and the low-level measuring section 302 can be realized.

In summary, the micro switch OP value detection and conversion device of the present utility model is provided with a base 1, a limiting jig 2, a measuring jig 3, a measuring contact 4, and a button switch 5, respectively; one end above the base 1 is provided with the limiting jig 2; the other end above the base 1 is provided with the measuring jig 3; the three measuring contacts 4 are arranged on the other side surface of the limiting jig 2 relative to the measuring jig 3; the button switch 5 has two pin sets 501 and a button handle 502; each pin group 501 is provided with three pins 501a; the three pins 501a are correspondingly and electrically connected with the three measuring contacts 4; when the knob 502 is operated, the different pin groups 501 are switched to conduct with the measuring contact 5. When the knob switch 5 switches its own switching path, the OP value can be measured for a switch having a different structure without changing the measuring device. Therefore, the micro-switch OP value detection conversion device solves the technical problem of how to improve the use universality of the switch OP value measurement device, and effectively reduces the use cost of the switch OP value measurement device.
