Description
Technical field
The present invention relates to a kind of appliance switch, particularly a kind of reed switch assembly.
Background technology
Reed switch is a kind of near switch, be widely used in push-button switch, detect whether the door of household appliances open and close near the fields such as anchor relay in switch and the temperature sensor equitemperature controller.
The basic structure of reed switch is: an inner glass tube of enclosing nitrogen, be packaged with two magnetic reeds that be arranged in parallel spaced reciprocally in this glass tube, and the lead-in wire of described magnetic reed is drawn from the two ends of glass tube respectively; The magnetic reed of described two spaced and parallel settings be subjected to magnetic force do the time spent contact that attracts each other, when not being subjected to magneticaction, disengage.Reed switch and reed switch support are formed the reed switch assembly that is suitable for installing together.
As shown in Figure 1, reed switch assembly 1a comprises: glass tube 3, two magnetic reeds 2 and reed switch supports 4; Described two magnetic reeds 2 be arranged in parallel spaced reciprocally and are encapsulated in the glass tube 3, and the lead-in wire of two magnetic reeds 2 is drawn from the two ends of glass tube respectively; Described glass tube 3 is arranged in the upper space of reed switch support 4; Described reed switch support 4 bends a quarter bend respectively with the lead-in wire of two magnetic reeds 2 and draws.
Described glass tube 3 is the uniform glass tubes of diameter; The bottom of described reed switch support 4 is formed with two and is used for reed switch assembly 1a is assembled to hook 410 on the substrate.
When having the reed switch assembly 1a place in circuit work of said structure, when reed switch near magnet or when having the object of magnetic, under the effect in magnetic field, two magnetic reeds 2 in the glass tube 3 attract each other and 210 are in contact with one another in the contact site, mutual conduction between two magnetic reeds 2, thereby the operating state of other devices in the control circuit.
The shortcoming of above-mentioned existing reed switch assembly is: when reed switch was subjected to extraneous impact, strenuous vibration can take place in the magnetic reed in the glass tube, and the magnetic reed knocks glass tube easily in the strenuous vibration process, cause the glass tube breakage sometimes.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of above-mentioned existing reed switch assembly, and the not reed switch assembly of cracky of a kind of glass tube with shockproof function is provided.
In order to solve described technical problem, the technical solution used in the present invention is: reed switch assembly of the present invention comprises: be used for cover glass pipe and guide the lead-in wire of magnetic reed to draw the reed switch support of direction, be arranged on the glass tube in the upper space of reed switch support and be encapsulated in two magnetic reeds that be arranged in parallel spaced reciprocally in the glass tube; The lead-in wire of described two magnetic reeds passes the two ends of glass tube respectively and along drawing with the perpendicular direction of the length direction of glass tube, and the lead-in wire of derivative two magnetic reeds is formed with a bending that has been used for cushioning effect respectively; The diameter at the two ends of described glass tube relatively with the diameter increase of the other parts of glass tube, form an expanded in diameter end respectively; On the described reed switch support corresponding to being formed with the cavity that holds that is used for holding expanded in diameter end and bending on the position of expanded in diameter end and bending respectively.
The bending of described two magnetic reeds lead-in wire is " V " font.
The bending of described two magnetic reeds lead-in wire also can be " U " font.
The diameter of the bending part lead-in wire of described two magnetic reeds lead-in wire is littler than the diameter of other position lead-in wires.
The expanded in diameter end at described glass tube two ends is spherical in shape.
The invention has the beneficial effects as follows: simple in structure, shockproof effect is remarkable.Not only the bending of magnetic reed can be impacted to external world and play cushioning effect, and the expanded in diameter end at glass tube two ends can evenly disperse vibrational energy, thereby has avoided the disrepair phenomenon of glass tube, has increased the functional reliability of reed switch assembly.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
As shown in Figure 2, present embodiment reed switch assembly comprises: be used for cover glass pipe 3 and guide the lead-in wire of magnetic reed 2 to draw the reed switch support 4 of direction, be arranged on the glass tube 3 in the upper space of reed switch support 4 and be encapsulated in two magnetic reeds 2 that be arranged in parallel spaced reciprocally in the glass tube 3; The lead-in wire of described two magnetic reeds 2 passes the two ends of glass tube 3 respectively and along drawing with the perpendicular direction of the length direction of glass tube 3, and the lead-in wire of derivative two magnetic reeds 2 is formed with a bending 200 that has been used for cushioning effect respectively; The diameter at the two ends of described glass tube 3 relatively with the diameter increase of the other parts of glass tube, form an expanded in diameter end 300 respectively; Be formed with respectively on the position corresponding to expanded in diameter end 300 and bending 200 on the described reed switch support 4 be used for holding expanded in diameter end 300 and bending 200 hold cavity 400.
The bending 200 of described two magnetic reeds, 2 lead-in wires is " V " word or " U " font.
The diameter of the bending 200 places lead-in wire of described two magnetic reeds, 2 lead-in wires is littler than the diameter of other position lead-in wires.
The expanded in diameter end 300 at described glass tube 3 two ends is spherical in shape.
Shockproof principle to present embodiment reed switch assembly is illustrated below:
When the reed switch assembly is subjected to foreign impacts, magnetic reed 2 produce vibration and with this transfer of vibration to glass tube 3.Owing to be formed with a bending 200 respectively on the lead-in wire of two magnetic reeds 2, so the vibration that magnetic reed 2 produces at first sponges a part by bending 200, just is delivered on the glass tube 3 then.
Because the bending 200 on the lead-in wire of two magnetic reeds 2 is " V " word or " U " font, and the diameter of the bending 200 places lead-in wire of two magnetic reed 2 lead-in wires is littler than the diameter of other position lead-in wires, so when the reed switch assembly is subjected to impacting, bending 200 places of two magnetic reed 2 lead-in wires are easy to take place deformation, thereby play bigger cushioning effect, make the vibration that is delivered to glass tube reduce significantly.
In addition, because the expanded in diameter end 300 at glass tube 3 two ends forms a sphere that diameter is bigger respectively, so when residual vibrations after bending 200 bufferings that go between through two magnetic reeds 2 are delivered on the expanded in diameter end 300 at glass tube 3 two ends, vibrational energy can be evenly dispersed on the expanded in diameter end 300 at glass tube 3 two ends, reduced to be delivered to the vibrational energy on glass tube 3 bodies greatly, avoid the disrepair phenomenon of glass tube 3, increased the functional reliability of reed switch assembly.
