Abstract
The utility model relates to a plug contact structure of an electric plug-socket switch, which is used for forming a contact couple with a plug-socket contact. A plug contact is composed of a tail conical shaft section with a ball head, a middle cylindrical shaft section and an upper stepped shaft section with a larger diameter. One side of the upper end stepped shaft section projects a flat table in radical direction. Two sides of the flat table are connected with the cylindrical surface of the cylindrical shaft section in tangency. Moreover, the two sides are symmetrically slanted toward the center line of the flat table, and the top view projection of the flat table forms a shape with narrow external sides and wide inner sides. A screw hole of a conducting wire fastening end is arranged on the radial center of the flat table. The utility model has good conductivity, good manufacturability, low manufacture cost, etc.
Description
The utility model relates to electric connector seat switch, refers in particular to a kind of plug connector structure of electric connector seat switch.
Connector assembly switch power supply gas, low-voltage equipment and automation equipment connecting circuit use, in the connector assembly switch, its plug, socket contact being conductive pieces, be the connector assembly switch core partly and the way of contact of conductive pieces, with conductive effect direct relation is arranged, because the energising part has a resistance and generates heat, because thermal effect, electrically conductive elastic spare can produce stress relaxation and electric contact piece is exerted an influence, so contact is to directly having determined electro-contact effect with contact form, contact is one of essential condition of decision contact quality to structure.In the prior art, usually adopt two kinds of contacts to structure, a kind ofly constitute by moving plate plug and still socket, its contact is to being the some contact, the reliability of the contact point that this contact is right is relatively poor, another kind of contact is to being made up of the contact pin of round pin shape and the socket of distinguish collar shape, and this contact is to being the line contact, and its contact reliability is better.And the contact pin of round pin shape is generally ladder circular shaft structure, there is thinner bulb round pin the lower end as contact pin, contact with socket aperture, there is thicker ladder circular shaft the upper end, hollow, one screw is laterally arranged, be used to connect lead, this stepped circular shaft is because the center is subjected to responsive to axial force, the contact plate washer is damaged easily, and fail safe is relatively poor, is had the pin connectors of radially protruding platform to replace by a kind of on the thick axle of upper end ladder, but this have a pin connectors processing difficulties of radially protruding platform, and production cost is higher.
The purpose of this utility model provides a kind of plug connector structure of the electric connector seat switch that has improved, and make its electric conductivity good, and processing technology is better, and manufacturing cost is lower.
Used technical scheme, the plug connector structure of connector assembly switch of the present utility model, it is right to be used for contacting with the receptacle contact composition, described plug connector is by the conical shaft part of not holding, the cylindrical shaft part and the bigger ladder shaft part of upper part diameter at middle part constitute, described conical shaft part top is a bulb, one side of described upper end ladder shaft part has the platform that radially protrudes, the upper surface of this platform is lower than the upper surface of ladder shaft part, the lower surface of this platform is higher than the faying face of ladder shaft part and cylinder shaft part, and the axial hole that described platform front end face center has radially screw and ladder shaft part center, upper end to be used to be connected lead communicates.
In preferred embodiment, the ladder shaft part that described plug connector upper end diameter is bigger is cylindrical, two sides of the platform that the one side is radially protruded and the face of cylinder of ladder shaft part are tangent, and this dual side-edge symmetry to the platform center line tilt to make the downward projection of this platform be outside the shape of narrow inner width.
The utility model has following positive beneficial effect:
1. plug connector of the present utility model is the round pin shape contact pin that bulb is arranged of terminal band tapering, and it is right to contact with the socket composition of distinguish lantern ring type, realizes resilient line contact, and its fail safe and reliability are higher.
2. the upper end shaft part of plug connector of the present utility model has radially outstanding boss, and the reach of the horizontal screw that extended is connected firmly screw.
3. described radially boss 3 two sides have gradient, thereby are suitable for adopting the mechanical compression mode to make and have the special-shaped section bar of boss, and revolve the processing car with car then and go out the ladder circular shaft, and circular cone and bulb, the processing technology of this section bar is better, and manufacturing cost is lower.
Now in conjunction with the accompanying drawings with preferred embodiment:
Fig. 1 is that plug connector of the present utility model contacts right schematic diagram with the receptacle contact composition.
Fig. 2 is the plug configuration schematic diagram of the cylindrical pin shape before improving.
The same Fig. 2 of Fig. 3 is its vertical view.
Fig. 4 be after the utility model improves cylindrical pin shape the radially plug configuration schematic diagram of boss arranged.
The same Fig. 4 of Fig. 5 is its vertical view.
See also Fig. 1, it is right that plug connector 2 of the present utility model is used for contacting with receptacle contact 1 composition conduction.
Fig. 2 Fig. 3 shows the structure of the plug connector 2 of the cylindrical pin shape before improving, by forming by the thin straight pin 22 and the bigger ladder shaft part 23 of upper end diameter of bulb 24, shaft part 23 has hollow hole 33, this hollow hole 33 communicates with horizontal screw 34, hollow hole 33 is used to penetrate the lead termination, is screwed into from screw 34 with screw the lead termination is fixed.
The structure of the plug connector 2 of connector assembly switch of the present utility model is seen Fig. 4 Fig. 5, this plug connector contacts seeing Fig. 1 with receptacle contact 1 composition, described plug connector 2 is by the conical shaft part of not holding 21, the cylindrical shaft part 22 and the bigger ladder shaft part 23 of upper part diameter at middle part constitute, described conical shaft part 21 tops are bulb 24, one side of described upper end ladder shaft part 23 has the platform 25 that radially protrudes, the upper surface 26 of this platform 25 is lower than the upper surface 27 of ladder shaft part, and the lower surface 28 of this platform is higher than the faying face 29 of ladder shaft part 23 and cylinder shaft part 22.Described platform 25 front end face centers have the axial hole 33 that is used to be connected lead of radially screw 34 and ladder shaft part 23 centers, upper end to communicate.
In preferred embodiment, described plug connector 2 usefulness copper materials are made.
The ladder shaft part 23 that described contact upper end diameter is bigger is cylindrical, two sides 30,31 of the platform 25 that the one side is radially protruded and the face of cylinder of cylindrical shaft part 22 ladder shaft parts 23 are tangent, and these dual side-edge 30,31 symmetries tilt to make the downward projection of this platform 25 to be the shape of outer narrow inner width to platform center line 32, the moulding when being beneficial to section bar and pushing.
