The shapes of pin bores 5 is using round (including oval, positive round and kidney ellipsoid etc.) and rectangular (including square, rectangular At least one of shape etc.), when the pin 6 when grafting is using round wire rod, round pin bores 5 are selected, when drawing to grafting When foot 6 is using flat wire formation, square pin hole 5 is selected to select suitable shape when the wire shape difference of pin 6 Pin bores 5 and pin 6 cooperate so that pin 6 is easier to be put into pin bores 5.

Embodiment two:

The present embodiment two provides a kind of transformer, specifically a kind of transformer with bottom plate.

Referring to FIG. 7, the transformer 11 includes magnetic core 3, be wound with coil 4 on magnetic core 3, coil 4 include primary coil and Several secondary coils.

Referring to FIG. 8, the inductor 1 further includes bottom plate 2, bottom plate 2 includes plate body 21.In the present embodiment, plate body 21 Shape is rectangle, in other embodiments can also be using other shapes such as circles.Pairs of pin bores are offered on plate body 21 5, the pin 6 of coil 4 runs through pin bores 5, Nian Jie by glue between coil 4 and plate body 21.

In each pair of pin bores 5, two pin bores 5 extend to direction close to each other or separate, define prolonging for pin bores 5 Stretching direction is its length direction, i.e. two pin bores 5 direction close to each other or separate is length direction, such as a institute in Fig. 8 and 10 Show direction.The direction perpendicular to length direction of pin bores 5 is width direction, the direction as shown in b in Fig. 8 and 10.It defines to be inserted The direction parallel with 5 length direction of pin bores for connecing pin 6 is the length direction of pin 6, defines to grafting pin 6 and pin The parallel direction of 5 width direction of hole is the width direction of pin 6.

In the present embodiment, the length direction of pin bores 5 is parallel with the length direction of rectangular base plate 2, the width of pin bores 5 Direction is parallel with the width direction of rectangular base plate 2.Pin bores 5 are inserted into for the ease of pin 6, the present embodiment makes the length of pin bores 5 The ratio between degree and width are greater than the ratio between length and width of pin 6.The width of pin bores 5 is adapted with the width of pin 6, Xiang Shi With width of the width slightly larger than pin 6 for referring to pin bores 5.

In the present embodiment, when the width of pin bores 5 is adapted with the radial dimension of pin 6, the hole of one side pin bores 5 Wall will not hinder pin 6 to be embedded in pin bores 5, and on the other hand, after pin 6 and 5 grafting of pin bores, the hole wall of pin bores 5 exists Pin 6 is limited in width direction, so that pin 6 is not easy to move along the width direction of pin bores 5.

Further, with continued reference to FIG. 8, in a kind of embodiment, the distance between each pair of pin bores 5 most outer a1 is less than The distance between two corresponding pins 6 to grafting.It should be noted that the most outer of pin bores 5 refers to pin bores 5 in length The outermost position in direction, distance a1 refers to the linear distance between two most outers of pin bores 5, as shown in a1 in Fig. 8.Fig. 8 In in order to illustrate distance a1, the pin 6 in corresponding pin hole 5 is omitted.

Referring to FIG. 9, the bottom symmetrical of coil 4 is formed with a pair of pins hole 5, this between the most outer of pin bores 5 away from From the distance between two corresponding pins 6 being less than to grafting.It, will when needing for be inserted into pin bores 5 pin 6 of coil 4 Two corresponding pins 6 are pushed to direction close to each other, shorten the distance between two corresponding pins 6, so that two corresponding pins 6 It can be embedded in a pair of pins hole 5.After pin 6 is embedded in pin bores 5, the pin 6 of pressing state is unclamped, pin 6 is at itself It is pushed against under the action of elastic force with the hole wall outer of pin bores 5, so that pin 6 is not easy to move in larger-size pin bores 5, When solving the problems, such as pin 6 and the excessive gap of pin bores 5 pin 6 be easy in pin bores 5 movement cause to position it is unstable.

In addition, in other embodiments, the distance between each pair of most interior edge of pin bores 5 can also be greater than two to grafting The distance between corresponding pin 6.Referring to FIG. 8, the distance between each pair of most interior edge of pin bores 5 is as shown in a2 in Fig. 8, pin bores 5 most interior edge refers to the position innermost in length direction of pin bores 5, and distance a2 is also referred between the most interior edge of two pin bores 5 Linear distance.

When needing for a pair of pins 6 to be inserted into pin bores 5, two corresponding pins 6 are pushed in the direction away from each other, Increase the distance between two corresponding pins 6, two corresponding pins 6 are embedded in a pair of pins hole 5, pin 6 is embedded in After in pin bores 5, unclamp the pin 6 of open configuration, pin 6 under the action of natural resiliency power with edge in the hole wall of pin bores 5 It pushes against, so that pin 6 is not easy to move in larger-size pin bores 5, when solving pin 6 and the excessive gap of pin bores 5 Pin 6, which is easy the movement in pin bores 5, to be caused to position unstable problem.

Further, the length of pin bores 5 is 1.5 times to 3 times of its width, in the present embodiment, the length of pin bores 5 It is 2 times of its width.

Referring to FIG. 10, plate body 21 is rounded in another bottom plate, three pairs of pin bores 5 are arranged at intervals on plate body 21, Three pairs of pin bores 5 are radially distributed, and are extended between two corresponding pin holes 5 to direction close to each other, each pair of most outer of pin bores 5 The distance between be less than the distance between two corresponding pins 6 to grafting so that being plugged on the pin 6 in each pair of pin bores 5 It is pushed against with the hole wall outer of pin bores 5.

One end of plate body 21 is provided with chamfering 9, and the shape of chamfering 9 and effect please refer to embodiment one.

A prosthetic foot hole location 10 is offered respectively on four angles of rectangular panel body 21 shown in Fig. 8, prosthetic foot hole location 10 Effect please refers to embodiment one.

The shapes of pin bores 5 is using round (including oval, positive round and kidney ellipsoid etc.) and rectangular (including square, rectangular At least one of shape etc.), in the present embodiment, the shape of pin bores 5 is all made of kidney ellipsoid, selects the side of 5 shape of pin bores Method please refers to embodiment one.
