Specific embodiment

For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is more fully retouched State.Preferred embodiment of the present utility model is given in accompanying drawing.But, the utility model can come real in many different forms Existing however it is not limited to embodiment described herein.On the contrary, providing the purpose of these embodiments to be to make to public affairs of the present utility model The understanding opening content is more thoroughly comprehensive.

Unless otherwise defined, all of technology used herein and scientific terminology are led with belonging to technology of the present utility model The implication that the technical staff in domain is generally understood that is identical.In term used in the description of the present utility model it is simply herein The purpose of description specific embodiment is it is not intended that limit the utility model.

In one embodiment, with reference to Fig. 1 and Fig. 2, a kind of riveting type dc male providing, including shell 1, insulating base 4, Center pin 2, positive terminal 6 and negative terminal 5, the front end of described shell 1 is arranged with dead ring 7, and the rear end of described shell 1 is embedding Enter described insulating base 4 so that being wrapped in insulating barrier 41 on the rear end outer wall of described shell 1；The central point edge of described insulating base 4 is outer The front extreme direction of shell 1 is provided with center pin 2；One end of described positive terminal 6 and negative terminal 5 is plugged in described insulating base 4, institute State positive terminal 6 to be connected with described center pin 2, described negative terminal 5 is connected with connection sheet 3, described connection sheet 3 and shell 1 Inwall offsets；The other end of described positive terminal 6 and described negative terminal 5 is respectively equipped with riveting portion, and described riveting portion includes leading Body riveting portion 60 and insulating barrier riveting portion 61.

Traditional welding formula terminal is replaced so that riveting type dc male is completely permissible in an assembling process by riveting type terminal Human weld is replaced by machine riveting, improves production efficiency, without the need for the training of butt welding catcher, reduce and produce into This.Due to the dual riveting being connected through conductor riveting portion and insulating barrier riveting portion of power line and riveting type dc male, Make the connection of power line more firm.Insulating barrier riveting portion can when power line swings stress, thus avoid power line Conductor wire is departed from conductor caulking part, improves the conductive stability of riveting type dc male.

In one embodiment, with reference to Fig. 1, a kind of riveting type dc male providing, the rear end outer wall of described shell 1 sets There is the concave point 8 in described insulating base for some depressions.

In the present embodiment, concave point makes casing deformation and is embedded in insulating base so that shell is difficult for drop-off with insulating base, Due to need not by injecting glue make that shell is combined with insulating base more firmly so that riveting type dc male assemble more convenient and quicker and Save cost.Specifically, described concave point is distributed in the parcel edge of insulating barrier on the outer wall of described shell.Preferably, institute State concave point quantity and be two, the central point connecting insulating base described in straight-line pass of described two concave points.

In one embodiment, with reference to Fig. 1 and Fig. 2, conductor riveting portion 60 comprises the first Baltimore groove 601, and described first is recessed The opposite position in both sides of shape groove 601 is respectively provided with the first riveting angle 602, and described insulating barrier riveting portion 61 comprises the second Baltimore groove 612, The opposite position in both sides of described second Baltimore groove 612 is respectively provided with the second riveting angle 611, described first Baltimore groove 601 and described the Two Baltimore grooves 612 connect.

In the present embodiment, in assembling process, power line is lain in first Baltimore groove and the second Baltimore groove of connection, its The exposed conductive filament of middle power line is located in the first Baltimore groove, and the power line having wrapped up insulating barrier is located at the second Baltimore groove Interior.By terminal machine or the direct punching press of special cutting die, the first riveting angle and the second riveting angular relative direction riveting are deformed, Make a concerted effort the conductive filament that is engaged power line from relative direction in the first riveting angle after deformation, the opposite position in the second Baltimore groove both sides Second riveting angle makes a concerted effort tightly to be engaged the insulating barrier of power line.Riveting type dc male is passed through terminal machine and can whole be used Mechanization assembles, and substantially increases production efficiency without human weld.Specifically, described first Baltimore groove 601 and second is recessed Shape groove 612 is V-shaped structure.

In one embodiment, as shown in Fig. 2 described first riveting angle 602 and the second riveting angle 611 are tied for rectangle claw-like Structure.The riveting angle of rectangle claw-like structures increase the conductive filament of power line and insulating barrier respectively with center pin terminal and earth terminal Son between contact area so that riveting angle can be more firm catch power line.

In one embodiment, with reference to Fig. 1 and Fig. 2, described second riveting angle 611 is more than the first riveting angle 602.Due to electricity In the line of source, the volume of the insulating barrier than power line for the conductive filament is little so that both rivetings can be more firm, need by Second riveting angle design more than the first riveting angle.

Above example only have expressed several embodiments of the present utility model, and its description is more concrete and detailed, but simultaneously Therefore the restriction to the utility model the scope of the claims can not be interpreted as.It should be pointed out that the ordinary skill for this area For personnel, without departing from the concept of the premise utility, some deformation can also be made and improve, these broadly fall into this The protection domain of utility model.Therefore, the protection domain of the utility model patent should be defined by claims.
