2, technical scheme:
In order to reach above-mentioned goal of the invention, technical solutions of the utility model are: the plug-in type binding post, and be connected jack spare by the metal inserting terminal with metal and constitute, metal connects jack spare and is connected electrical connector or electric connection line respectively with the metal inserting terminal; The metal inserting terminal inserts metal and connects in the jack spare, described metal inserting terminal is the cylindricality inserting terminal, it is cylindricality jack spare that metal connects jack spare, one end of cylindricality inserting terminal injects in the cylindricality through hole of cylindricality jack spare, is provided with at least one fluting at cylindricality jack spare along its cylinder lateral wall length direction.Especially be provided with a pair of fluting that runs through this cylinder wall at cylindricality jack spare symmetrically along its cylinder lateral wall length direction.
The cylindricality inserting terminal is cylindrical inserting terminal, and cylindricality jack spare is the cylindrical receptacle part.The cylindricality inserting terminal can the cross section be ellipse or regular polygon also, and cylindricality jack spare cross section also is corresponding shape.
The cylinder lateral wall of cylindricality jack spare is provided with three flutings along its length equably.
The cylinder lateral surface of cylindricality jack spare is provided with an annular recess part, and annular recess partly is provided with a Spring steel shroud, is wrapped in this cylinder outer wall.
The afterbody of cylindricality jack spare uses when being connected for wiring with clamp bodies such as screw or springs.
The plug-in type binding post of the technical program also comprises insulation shell, and metal connects jack spare and the metal inserting terminal is contained in this insulation shell, and insulation shell is provided with clamp body mount pad and trip bolt.
In order to optimize the electric conductivity of the technical program plug-in type binding post, cylindricality inserting terminal and cylindricality jack spare electroplate.
One end of cylindricality inserting terminal injects cylindricality jack spare, and the other end is provided with an assembly welding pin, cylindrical inserting terminal can be welded in by this leg on the electric device such as pcb board.
When the plug-in type binding post of the technical program is worked, the cylindricality inserting terminal inserts in the cylindricality through hole of cylindricality jack spare, in this cylindricality through hole, the inner surface of the outer surface of cylindricality inserting terminal cylinder and cylindricality jack spare through hole is in contact condition, thereby reaches the purpose of electrical connection.When cylindricality inserting terminal and cylindricality jack spare are all when cylindrical, the outer surface of cylindricality inserting terminal cylinder is that circular face contacts with the inner surface contact condition of cylindricality jack spare through hole, and the effect of electrical connection is better.
3, beneficial effect: the utility model provides a kind of plug-in type binding post that adopts the special construction plug connector, the column electrical connector that is adopted has increased the contact area of current-carrying part, thereby the ability of transmission current is increased greatly, following advantage is arranged: (1) conductive connection part divides the mode that adopts the circular face contact, long-pending the comparing with existing plug-in type binding post greatly of conductive contact surfaces increases, discharge capacity is bigger, and maximum can reach 125A; (2) simple in structure, be easy to processing, production cost is low; (3) plug is convenient to operation; (4) after plug repeatedly, still can keep excellent conducting performance; (5) leg adopts the design of spininess position, has reached shunting effect, the stability that has improved heat-sinking capability and welded on pcb board.
