Specific embodiment

As shown in Figures 1 to 7, it is a kind of can full-automatic production safety transformer, including transformer framework 1 and The magnetic core 3 being installed on transformer framework is coated with shell 2 on the outside of the transformer framework.

As shown in Figure 1 to Figure 2, the transformer framework is equipped with through-hole 100 up and down, the transformer along central axes The upper and lower ends of skeleton are equipped with end plate 101 and form the winding slot 102 for transformer coiling, the transformation between two end plates The upper and lower ends of device skeleton are correspondingly provided with the first primary pins bracket 11 and the second primary pins bracket 12, the transformer framework Upper and lower ends be correspondingly provided with the first time for being fixed temporarily secondary lead end head after the completion of transformer framework coiling Grade wiring column 13 and second subprime wiring column 14, the circumferential position of the first primary pins bracket and the second primary pins bracket With the circumferential position interval 180 degree of first grade wiring column and second subprime wiring column, the first secondary pins bracket, second The centre of secondary pins bracket, first grade wiring column and second subprime wiring column is equipped with separation trough, first grade hanging wire Column and the second primary pins bracket offer separated time slot 16, the first primary pins bracket on the symmetrical two sidewalls of separation trough Equipped with salient point 111 protruding upward.

The second subprime pin bracket is equipped with square PIN needle foot 121.Broken string is conducive to using square PIN needle foot.Such as Fig. 3 institute Show, stitch side inlet-outlet line is collided in order to avoid primary and secondary causes pressure-resistant hidden danger, using low inside and high outside bevel edge structure 17.

The bottom surface of the separation trough concordant with winding slot corresponding surface 15 is conducive to automatic machine without step and fluctuating point in this way Outlet and avoiding collide with next group of winding and caused by security risk.

As shown in Figure 4 and Figure 5, the magnetic core 3 sets there are two and includes bottom plate, and the middle part of the bottom plate is vertically equipped with slotting Enter the center pillar 31 in through-hole, the two sides of the bottom plate are equipped with side plate 32 that is vertical with bottom plate and protruding in the same direction with center pillar；In described Column 31 uses ellipsoidal structure, while through-hole engaged therewith 100 is also ellipsoidal structure, the bottom plate side plate and center pillar it Between form fan-shaped transition structure.The AE of oval center pillar is bigger, more efficient in the case where not increasing bigger special case.It is fan-shaped Transition structure is left a blank at inner arc end and center pillar junction to form outlet gap, therefore being conducive to cooperation transformer framework uses it Automatic machine outlet.

As shown in Figure 6 and Figure 7, the shell 2 include bottom wall, rear wall and the side wall of the left and right sides, the bottom wall, rear wall with The rear wall bottom that shell described in the installation cavity of the skeleton of installation transformer is surrounded between the side wall of the left and right sides is equipped with secondary pins branch Frame 21, the secondary lead end head pulled out from secondary wiring column are fixed on secondary pins bracket and form secondary pins.The One primary pins bracket and the second primary pins bracket are prominent from front openings, and rear wall upper end is equipped with groove 25 in order to for the first time Grade wiring column is put into.Bottom wall front shape corresponding with magnetic core bottom plate chamfered shape 24.

Wherein, the leading edge of side wall is equipped with folding of turning on one's side backward to stop the retaining wall 23 of magnetic core, and the rear side of the side wall is equipped with The forwardly convex boss 22 with retaining wall cooperation clamping transformer framework.It in this way installs magnetic core and transformer framework to stablize.

The secondary pins bracket is equipped with the arc-shaped line outlet 211 and PIN foot of a row.It is larger in electric current, lead compared with When thick, secondary lead end head can directly engage with arc-shaped line outlet and fixation forms secondary pins, smaller in electric current, secondary When grade lead is thinner, secondary lead end head can be fixed in PIN foot, form secondary pins, therefore size of current It uses.

To sum up, transformer of the invention, which has, improves assembly automation, reduces cost of labor, reduces labor intensity of workers Advantage, while also complying with anti-EMI filter and shield effectiveness.
