Abstract
The utility model relates to an in-line quick connection contact pin for replacing a solid flat contact pin of an electric energy meter, wherein the fore of the contact pin is an arc terminal, the middle is provided with an elastic fastener and the rear is an open elastic ring. The utility model has the advantages that firstly the in-line quick connection contact pin is adopted to remove screws in the terminals, thereby no screws take-up procedure is required and the production rate is increased by more than two times. Secondly the contact quality of the contact pin and the terminals are ensured. Thirdly this novel conformation for assisting with the electric energy meter quick connection is created with novel, unique, simple, reliable and practical conformation.
Description
Technical field:
The utility model relates to a kind of direct insertion terminal fast-wiring contact pin that is used to replace the solid flat contact pin of electric energy meter, belongs to the electric energy meter parts and makes the field.
Background technology:
Existing electronic electric energy meter has a lot of auxiliary terminals, and 2 at least, 26 at most, the three-phase table is generally all about 18.Past all is solid flat contact pin, earlier contact pin is inserted in the terminal copper bar hole, and then tighten up with the M2.5 screw, for prevent terminal box supply producer in transit screw come off by vibration, therefore all screws all are in urgent state and offer main dress factory, we must unclamp screw earlier before the dress contact pin, urgent again screw behind the insertion contact pin.Particularly sometimes because of influences such as screw aperture or screw taps, also can produce the sliding tooth of screw, screw thread leaks problem such as attack.So just must change problematic copper bar, both time-consuming, effort and quality are difficult to again guarantee.
Summary of the invention:
Purpose of design: avoid the weak point in the background technology, design and a kind ofly need not fastening contact pin and can stop the come off direct insertion terminal fast-wiring contact pin of (terminal) of contact pin vibration.
Design proposal: in order to realize above-mentioned purpose of design.On structural design, direct insertion terminal fast-wiring contact pin front end is near round end, and purpose is to be convenient to import in the hole of terminal; (portion) is provided with a buckle in the middle of the fast-wiring contact pin, and purpose one is to prevent that the fast-wiring contact pin from being vibrated and deviate from terminal, the 2nd, if once in a while with the contact pin wrong plug position, hole, also, very convenient as long as gently press buckle just can take out easily with little flat blade screwdriver; Fast-wiring contact pin tail (back) portion is the open circles (opening elastic ring) of an interference, and purpose makes the afterbody of fast-wiring contact pin and terminal endoporus form an elasticity interference fit, and assurance and terminal and fast-wiring contact pin are in the excellent contact state.Its technical scheme: direct insertion terminal fast-wiring contact pin, contact pin front end are that circular arc head (1), middle part are provided with an Elastic buckle (2), the rear portion is opening elastic ring (3).
The utility model is compared with background technology, and the one, direct insertion terminal fast-wiring contact pin has removed the screw in the terminal, therefore need not this road formality of slack adjuster, only this changes and enhances productivity more than two times; The 2nd, the contact quality of contact pin and terminal also is guaranteed; The 3rd, novel structure, uniqueness, simple, reliable, practical are started electric energy meter auxiliary terminal grafting new construction.
Description of drawings:
Fig. 1 is the main TV structure synoptic diagram behind the direct insertion terminal fast-wiring contact pin line.
Fig. 2 is the plan structure synoptic diagram of Fig. 1.
Embodiment:
Embodiment 1: with reference to attached Fig. 1 and 2.Direct insertion terminal fast-wiring contact pin, the contact pin front end is the circular arc head and the contact pin front end is opening or the circular arc head 1 of remaining silent, contact pin middle part is provided with rear portion that an Elastic buckle 2 and contact pin middle part have groove, contact pin and is opening elastic ring 3 and the opening elastic ring 3 diameters body diameter greater than circular arc head 1, there is the wiring compressing tablet opening elastic ring 3 rear ends, and compressing tablet is with the lead bag pressure and by heat-shrinkable T bush 4 insulation that is locked.Contact pin inserts in the terminal hole, the rear portion of its contact pin is interference with the terminal endoporus and contacts, and Elastic buckle 2 ends at contact pin middle part are stuck on the cinclides wall that communicates with the terminal endoporus, if once in a while with the contact pin wrong plug position, hole, as long as it is gently press buckle just can take out easily, very convenient with little flat blade screwdriver.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations only limit to explanation of the present utility model; rather than to restriction of the present utility model; anyly do not exceed innovation and creation of the present utility model, all fall in the protection domain of the present utility model.
