Description
Technical field
The present invention relates to a kind of contact pin.
Background technology
At present, in the full-automatic detection system of electric energy meter, need there be suitable detection contact pin to contact with the connection terminal of single-phase electric energy meter, guarantees less contact resistance.Owing to often will pass to high voltage, big electric current in the testing process, if probe is bad with contacting of single-phase electric energy meter, cause contact resistance bigger than normal, will cause generate heat hot, influence problems such as measuring error.
Contact pin structure at present commonly used is to have adopted the foward dome design, both can't satisfy the requirement that high voltage, big electric current pass through, and can not adapt to the connection terminal of current multiple table shape different size again.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is that the prior art scheme is improved and improved, and provides a kind of electric energy meter that is applicable to automatically to detect the contact pin of streamline, to reach the reliable and purpose applied widely of contact.For this reason, the present invention takes following technical scheme:
Be applicable to that electric energy meter automatically detects the contact pin of streamline, contact pin is the conductive stud contact pin, it is characterized in that: described contact pin comprises superposed pin for electrical connection connection box of electric energy meter terminal and is positioned at the contact pin body of bottom; The last end face of pin is offered the groove of dehiscing, and the described groove bottom of dehiscing is offered " one " font elastic groove; Described groove and the elastic groove of dehiscing is pre-and post perforative groove, and the top of pin is divided into two insertion sections of symmetrical outwards elastic bending deflection by dehisce groove and elastic groove.The shape of elastic groove and connection box of electric energy meter terminal match, contact pin pushes the connection box of electric energy meter terminal hole, the stressed insertion section, the left and right sides that makes of the groove of dehiscing that is positioned at its head is crooked laterally respectively, elastic groove broadens, the connection box of electric energy meter terminal hole is close in the outside of insertion section, surface of contact increases, and realizes large tracts of land, small resistor conduction.The dehisce shape of groove and the screw of connection terminal matches, contact pin is in the connection box of electric energy meter terminal hole moves ahead process, and the groove of dehiscing can be collided with screw, and contact pin continues to advance, the groove of dehiscing is stressed outwardly-bent to dodge screw, makes the lateral surface of insertion section be close to connection box of electric energy meter terminal hole wall.Be to make things convenient for entering of contact pin adding man-hour, contact pin and connection box of electric energy meter terminal hole are clearance fit, along with contact pin constantly enters in the connection terminal hole, it is big that the distortion of insertion section also constantly becomes, contact pin is contacted with the connection terminal hole wall reliably, adapt to the connection terminal of the interior different apertures of certain limit and shape.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature:
The described groove of dehiscing is the deep-slotted chip breaker parallel with elastic groove.The shape of securing member such as deep-slotted chip breaker and screw matches, and effectively avoids screw, can guarantee between contact pin and the connection box of electric energy meter terminal enough big surface of contact is arranged again simultaneously; And because the load area of elastic groove is bigger, Wear.
The last end face middle part of described pin has a up big and down small taper springhole, and springhole gos deep into elastic groove.Offer springhole, the corresponding wall thickness that reduces the insertion section makes the more flexible distortion in insertion section.And the taper springhole has guide effect, is conducive to the insertion of contact pin.
The big footpath of described springhole is equal to or greater than the width of the groove of dehiscing.Be beneficial to screw and import in the groove of dehiscing, be convenient to the insertion of contact pin and the bending of insertion section.
Described pin comprises superposed up-small and down-big conical section, is positioned at first cylindrical section, second cylindrical section and the three cylindrical section that is connected with the contact pin body of conical section below; The diameter of first cylindrical section, second cylindrical section, three cylindrical section increases successively.The pin head is taper, has guide effect, is beneficial to the insertion of contact pin.Second cylindrical section cooperates with the connection box of electric energy meter terminal hole, and first cylindrical section, second cylindrical section, three cylindrical section are arranged successively, and the deflection of first cylindrical section is also maximum, and small diameter shaft can prevent the interference of itself and connection box of electric energy meter terminal hole, is convenient to contact pin and enters.The flexural deformation of second cylindrical section can be close to the connection box of electric energy meter terminal hole and realize the purpose of high voltage, conducting heavy current.
The lateral surface cone angle of conical section is 40-60 °.Too small, be prone to the phenomenon that crooked back and connection box of electric energy meter terminal hole card end, too big, then do not have the effect of guiding.
The outside diameter of conical section is identical with the first cylindrical section diameter.
The elastic contact pin head of described pin for being made by beryllium copper, described contact pin body is the low resistance contact pin body that is made of copper, and docks by weld layer between the two.The pin good springiness, and the contact pin body conducts electricity very well.Take into account that surface of contact is big, resistance value is little, be fit to that high pressure is pressed, big current applications.
Beneficial effect:
1, the shape of elastic groove and connection box of electric energy meter terminal match, when contact pin pushes the connection box of electric energy meter terminal, the groove of dehiscing that is positioned at its head is stressed and make insertion section, the left and right sides crooked laterally respectively, the connection box of electric energy meter terminal hole is close in the outside of insertion section, surface of contact increases, and realizes the purpose of large tracts of land, small resistor conduction.
2, contact pin is in the connection box of electric energy meter terminal hole moves ahead process, the groove of dehiscing can be collided with screw, contact pin continues to move ahead, the groove of dehiscing is stressed outwardly-bent, make the lateral surface of insertion section be close to the connection box of electric energy meter terminal hole, dehisce the lateral surface of groove and insertion section simultaneously for the conducting surface surface of contact, and area is big, and resistance value is little.
3, contact pin and connection box of electric energy meter terminal hole are clearance fit, and along with contact pin constantly enters in the connection terminal hole, it is big that the distortion of insertion section also constantly becomes, and adapts to different connection terminal holes, and work flexibly.
4, pin good springiness, and the contact pin body conducts electricity very well takes into account that surface of contact is big, resistance value is little.
