Embodiment 1

A kind of transformer PIN foot protective device, as depicted in figs. 1 and 2, including shell 1, if the bottom of shell 1 is equipped with Dry PIN foot 2, the outside of PIN foot 2 are equipped with protective case 3, and the two sides of shell 1 offer fixation hole 10, under each fixation hole 10 Side offers limit hole 11, and the side of each limit hole 11 offers inclined-plane 12, and the bottom surface of shell 1 offers several bottom outlets 13.

Specifically, inclined-plane 12, between fixation hole 10 and limit hole 11, inclined-plane 12 is connected with limit hole 11, so that card It when column 32 is pressed, can voluntarily be slided out in fixation hole 10 from limit hole 11 along inclined-plane 12, realize the fixation of protective case 3, from And expose PIN foot 2.

Further, the quantity of bottom outlet 13 is four, and bottom outlet 13 is distributed in the corner of 1 bottom surface of shell.

Embodiment 2

As second of embodiment of the utility model, in order to avoid PIN foot extrusion, the present invention staff is provided with Protective case 3, as a kind of preferred embodiment, as shown in Figure 3 and Figure 4, the top surface of protective case 3 offers inner cavity 30, protective case 3 Top surface and close two sides are equipped with supporting plate 31, and the side of supporting plate 31 is equipped with card column 32, and the bottom surface of inner cavity 30 is equipped with several pillars 33, protects If the bottom surface of sheath 3 offers butt-swelling hole 34.

In the present embodiment, protective case 3 uses PP material, that is, polypropylene, and light and intensity is firm, keeps its durable.

Specifically, protective case 3 is in cuboid, inner cavity 30 and the socket of shell 1 cooperate, and under normal condition, protective case 3 passes through card The clamping of column 32 and limit hole 11 and limit, protect PIN foot 2 is not extruded or collides, and when needing to expose PIN foot 2, pushes up upwards Press protective case 3.

Further, card column 32 is engaged by clamping with fixation hole 10 and limit hole 11.

In addition to this, pillar 33 and bottom outlet 13 correspond, and the top of each pillar 33 is socketed with spring 330, spring 330 is mating with bottom outlet 13, and the limit by pillar 33 and bottom outlet 13 to spring 330 avoids its slippage, passes through spring 330 So that protective case 3 moves reciprocatingly on shell 1, consequently facilitating enabling protective case 3 at any time to protect PIN foot 2.

It is worth noting that, foot hole 34 is connected with inner cavity 30, foot hole 34 corresponds and is slidably connected with PIN foot 2, leads to Cross 34 second protection of foot hole PIN foot 2, and to PIN foot 2 have straightening effect.

The transformer PIN foot protective device of the utility model during installation, spring 330 is inserted in one by one in pillar 33, is made Foot hole 34 is directed at PIN foot 2, is located at supporting plate 31 on the side of fixation hole 10, pushes protective case 3, so that spring 330 is inserted into bottom outlet In 13, PIN foot 2 is inserted into foot hole 34, is protected, until card column 32 is caught in limit hole 11, is just installed successfully, is being used When, protective case 3 only need to be pressed, slides out to card column 32 in fixation hole 10 along inclined-plane 12, protective case 3 can be made firm, at this time PIN foot 2 also reveals, consequently facilitating being connected on circuit board.
