Description
Technical field
The present invention relates to a kind of anti-surge voltage electric connector socket, belong to technical field of electric connectors.
Background technology
In all kinds of electronic systems, electric connector is used for being electrically connected and the signal transmission between device and device, assembly and assembly, system and the system, is to constitute the necessary base components of holonomic system.The instantaneous rising of electrical system operating voltage when electronic system is interfered, its amplitude can reach several times～hundred times of rated operational voltage, and this interference signal is called voltage surge.The reason that produces voltage surge has: thunderbolt, facility switching static discharge and line fault.Voltage surge may cause the data distortion of communication system and lose, even cause electronic equipment to damage.If connector is not carried out the inhibition of surge voltage, will cause great harm to whole electronic system so.
Present common connector is in surface of shell plating high conductivity material, and when there was interference in the external world, interference signal flowed into ground wire by surface of shell, has so only realized electromagnetic shielding.And when having the surge voltage signal on the electric connector contact, common connector can't this interference signal of filtering.
Summary of the invention
The object of the present invention is to provide a kind of anti-surge voltage electric connector socket, solve electric connector socket existence as extraneous thunderbolt and surge voltage and enter in the transmission line, influence the problem of equipment operate as normal in the internal and external environment by contact.Make that this product can be used to be struck by lightning, the circuit between the system under facility switching, static discharge and the line fault environment connects, and possesses the ability of anti-surge voltage.
Anti-surge voltage electric connector socket of the present invention comprises shell, cover plate, pedestal, contact pin, also be provided with ground plate, Transient Suppression Diode, gas discharge tube and piezo-resistance simultaneously, described contact pin is welded on the printed board pad, piezo-resistance two ends pin all is welded in the printed board, Transient Suppression Diode, gas discharge tube one terminate on the printed board pad, the other end is realized Elastic Contact by spring coil and ground plate, ground plate and shell are fastenedly connected and guarantee and electrically contact, and shell links to each other with earth connection.
Irritating fluid sealant by two ends makes Transient Suppression Diode and gas discharge tube be sealed in socket inside.
When surge voltage was added on the contact pin, the Transient Suppression Diode fastest by the response time at first moved.By selecting suitable resistance, before Transient Suppression Diode may damage, along with the increase of discharging current makes it add that in the pressure drop that produces on the resistance pressure drop on Transient Suppression Diode reaches the puncture voltage of piezo-resistance, at this moment piezo-resistance begins discharge.Equally, make it add that in ohmically pressure drop the piezo-resistance puncture voltage reaches the operation voltage of gas discharge tube, finally discharge bigger surge current by gas discharge tube along with discharging current further increases.By above three grades of protection, the inhibition time of not only having improved surge voltage, more can improve the burst size of surge current.Thereby the circuit that protection socket contact is connected is not subjected to the impact of surge voltage and damages.Can effectively prevent intrusion such as moisture, harmful substance and this components and parts were lost efficacy.
After adopting the said structure scheme, that anti-surge voltage electric connector socket of the present invention has is simple in structure, complete function, anti-interference effect are good, stable and reliable for performance, be applicable to that electric connector needs the application scenario of highly reliable anti-surge voltage, can satisfy the user demand of novel device.

Embodiment
Below in conjunction with the accompanying drawing example anti-surge voltage electric connector socket of the present invention is described in further detail:
As shown in Figure 1, anti-surge voltage electric connector socket of the present invention comprises cover plate 1, shell 12, pedestal 13 and contact pin 24, also be provided with printed board 8 simultaneously, Transient Suppression Diode 16, gas discharge tube 17, resistance 18, resistance 19 and piezo-resistance 20, described contact pin 24 is welded on printed board 8 pads, resistance 18, resistance 19, piezo-resistance 20 two ends pins all are welded in the printed board, Transient Suppression Diode 16, gas discharge tube 17 1 terminate on printed board 8 pads, and the other end is realized Elastic Contact by spring coil 21 and ground plate 7, ground plate 7 is fastenedly connected with electric continuity with shell 12 with elastic washer 6 by screw 5 and contacts, and shell 12 will link to each other with earth connection.
Be provided with rubber blanket 4 between ground plate 7 and the cover plate 1, be provided with rubber blanket 9 between printed board and housing 12 base plates.
The said elements circuit diagram as shown in Figure 2, by with printed board 8 welding Transient Suppression Diode 16, gas discharge tube 17 and piezo-resistance 20 two ends being realized being electrically connected with shell 12 and contact pin 24 respectively, resistance 18,19 is serially connected between Transient Suppression Diode 16, gas discharge tube 17 and the piezo-resistance 20.Before the welding, printed board 8 is fixed on the ground plate 7 by screw 10, avoids Transient Suppression Diode 16 and gas discharge tube 17 directly stressed.Because ground plate 7 is made of the bulk metal plate; adopt welding to be difficult to realize; therefore Transient Suppression Diode 16 contacts with ground plate with gas discharge tube 17 and adopts spring coil 21 Elastic Contact to realize; simultaneously Elastic Contact better protection Transient Suppression Diode 16 and gas discharge tube 17 have improved the anti-vibration performance of product.Rubber blanket 4 is grounded plate 7 and cover plate 1 Elastic Contact, and rubber blanket 9 is realized printed board 8 and shell 12 Elastic Contact.
The anti-surge voltage circuit working process of anti-surge voltage electric connector socket of the present invention is: when surge voltage was added on the contact pin 24, the Transient Suppression Diode 16 fastest by the response time at first moved.By selecting suitable resistance 19, before Transient Suppression Diode 16 may damage, add that in the pressure drop that produces on the resistance 19 pressure drop on Transient Suppression Diode 16 reaches the puncture voltage of piezo-resistance 20 along with the increase of discharging current makes it, at this moment piezo-resistance 20 begins discharge.Equally, make its pressure drop on resistance 18 add that piezo-resistance 20 puncture voltages reach the operation voltage of gas discharge tube 17, finally discharge bigger surge current by gas discharge tube 17 along with discharging current further increases.By above three grades of protection, the inhibition time of not only having improved surge voltage, more can improve the burst size of surge current.
Anti-surge voltage electric connector socket of the present invention has adopted a large amount of Transient Suppression Diodes 16, gas discharge tube 17, piezo-resistance 20, resistance 18 and resistance 19, is not subjected to the influence of environmental condition for guaranteeing multicomponent device so, adopts all-sealed structure.At butt end and the tail end embedding fluid sealant 14 and the fluid sealant 23 of socket, avoid the moisture intrusion and cause that components and parts lost efficacy.
