A kind of radio-frequency relay is arranged at present, its electromagnetic drive mechanism comprises coil, the coil exit, yoke, moving iron core and catch bar, coil is installed in the yoke, the coil exit is positioned at the yoke top, and the coil exit is electrically connected with coil, moving iron core is made up of two parts, it is respectively the cylinder part that is linked in the coil, be positioned at the base portion of the below, lower surface of yoke, there is a fixed gap between the lower surface of base portion and yoke, the convenient moving iron core in this space moves up and down, the bottom of catch bar is passed yoke and is connected with moving top unshakable in one's determination, promptly the top with the cylinder part is connected, the top of catch bar is provided with back-moving spring, and the top of catch bar also is connected with the moving contact of radio-frequency relay.Concrete structure as shown in Figure 1.
There are following three defectives in above-mentioned radio-frequency relay, 1, owing to moving iron core is made up of two parts, it is respectively the base portion that is linked in cylinder part in the coil, is positioned at the below, lower surface of yoke, make that moving quality unshakable in one's determination is bigger, intrinsic resonance frequency is lower, thereby in whole operating temperature range, the poor work stability of radio-frequency relay when being subjected to sinusoidal vibration and random vibration; 2, owing to there is a fixed gap between the lower surface of base portion and yoke, cause in the magnetic circuit magnetic resistance and leakage field bigger, effectively flux interaction power is little, and it is little to cause moving under the operating state unshakable in one's determination confining force, and the dynamic and static contact force of radio-frequency relay is less; 3, because the window area of coil is subjected to spatial limitation, make that the working ampere turn of coil is few, under room temperature 25 degrees celsius, its operation voltage up to or surpass 90% of coil rating operating voltage.Comprehensive above 3 points, the functional reliability of existing radio-frequency relay is lower.
The utility model content
The technical problems to be solved in the utility model is, a kind of good operating stability can make radio-frequency relay be subjected to sinusoidal vibration and random vibration in whole operating temperature range the time is provided, can reduce magnetic resistance and leakage field, improve the useful flux active force, can reduce operation voltage, improve the radio-frequency relay electromagnetic drive mechanism of radio-frequency relay functional reliability.
The technical solution of the utility model is, the utility model radio-frequency relay electromagnetic drive mechanism, it comprises coil, the coil exit, yoke, moving iron core and catch bar, coil is installed in the yoke, the coil exit is positioned at the yoke top, and the coil exit is electrically connected with coil, the bottom of catch bar is passed yoke and is connected with moving top unshakable in one's determination, the top of catch bar is provided with back-moving spring, the top of catch bar also is connected with the moving contact of radio-frequency relay, it also comprises the fixed magnetic pole seat, the fixed magnetic pole seat is made up of cylinder part and these two parts of bottom, and cylinder partly is linked in the coil, and the bottom is positioned at the below, lower surface of yoke, and paste mutually or be fastenedly connected with the lower surface of yoke, described trunk portion is arranged with the through hole of bottom; Described moving iron core is a bar, and the top of bar is the pole shoe part, and the bottom of bar is a targeting part, and this targeting part cooperates with described via clearance.
After adopting said structure, the utility model compared with prior art, have the following advantages: because it also comprises the fixed magnetic pole seat, the fixed magnetic pole seat is made up of cylinder part and these two parts of bottom, cylinder partly is linked in the coil, the bottom is positioned at the below, lower surface of yoke, and pastes mutually or be fastenedly connected with the lower surface of yoke, and described trunk portion is arranged with the through hole that runs through the bottom; Described moving iron core is a bar, and the top of bar is the pole shoe part, and the bottom of bar is a targeting part, and this targeting part cooperates with described via clearance, and like this, moving iron core is more much smaller than prior art, makes that moving quality unshakable in one's determination is less, and intrinsic resonance frequency is higher; Cancelled the space that the moving iron core of original convenience moves up and down in the new structure, adopt fixed magnetic pole seat and the moving mode that cooperates unshakable in one's determination, on the one hand, make that magnetic resistance and leakage field reduce widely in the magnetic circuit, and the magnetic line of force concentrates on moving pole shoe part unshakable in one's determination, on the other hand, the structure that moving targeting part unshakable in one's determination cooperates with described via clearance makes moving iron core can produce screwed pipe power under the effect of exciting flux, and above-mentioned two aspects make effective flux interaction power increase; Be because cancelled the space that the moving iron core of original convenience moves up and down in the new structure equally, original gap can be used for increasing the window area of coil, cause working ampere turn to increase, make under room temperature 25 degrees celsius, its operation voltage is less than 70% of the coil rating operating voltage, overcome the original structure operation voltage up to or surpass 90% drawback of coil rating operating voltage.In sum, the utlity model has the good operating stability in the time of to make radio-frequency relay in whole operating temperature range, be subjected to sinusoidal vibration and random vibration, can reduce magnetic resistance and leakage field, improve the useful flux active force, can reduce operation voltage, improve the advantage of radio-frequency relay functional reliability.
