Description

The structure of power connection and conducting pin thereof

Technical field

The present invention relates to a kind of structure of power connection, relate in particular to a kind of structure that is applied to the AC power supplies joint of power supply device.

Background technology

The major function of power supply device is in order to after civil power (commercial power source) rectification, being converted to direct current, provides power receiving equipment (power-receiving device) to use.Fig. 1 (a) reaches and (b) is the assembly drawing and the stereogram of power supply device commonly used, and this power supply device mainly comprises loam cake 1, lower cover 2, forms a spatial accommodation between loam cake 1 and the lower cover 2, in order to place circuit board 3; A required electronic component 30 and the AC joint 4 of plant power supply device on the circuit board; The both sides, front and back of loam cake 1 form first recess 11 and the second recess (not shown) respectively, and with respect to first recess 11 and second recess, the both sides, front and back of lower cover 2 form the 3rd recess 21 and the 4th recess 22 respectively.When loam cake 1 with after lower cover 2 combines, 21 of first recess 11 and the 3rd recesses form a notch, go into AC joint 4 in order to down, to accept external communication; 3 of circuit boards are direct current with the AC rectification of being accepted, again by second recess and the 4th recess 22 formed slotted eyes, to export power receiving equipment to through the power supply of rectification with the power line (not shown), for example uses such as printer, broadcast receiver, modulator-demodulator.

Please see Figure 2 (a) reaches (b), AC joint 4 comprises insulating body 40, body interior is established a through hole 41, having first in the through hole 41 connects terminal 411, second and connects terminal 412 and earth terminal 413, first connects terminal 411, second connects the aperture (not shown) of terminal 412 and earth terminal 413 by body dorsal part 401, and is connected bonding pad 421,422 and 423 with first conducting pin 431, second conducting pin 432 and ground connection pin 433 respectively with the riveted joint mode.

Two poles 44 are formed on body bottom 402, and pole 44 and body 40 are to adopt that shoot mode is integrally formed to form, and pole 44 is fallen after the expansion of both sides respectively again and contracted and form outstanding structure 443 after length-specifics are extended downwards in body bottom 402.The maximum crosscut length of outstanding structure 443 is slightly larger than the width of the jack 33,34 of circuit board 3.Because pole 44 itself has the distinctive elasticity of plastic material, can make the outstanding structure 443 of pole 44 pass through jack 33,34 so impose an external force, be positioned on the circuit board 3 with auxiliary AC joint 4.

First conducting pin 431, second conducting pin 432 extend downwards so that be inserted in the pin hole 31,32 (consulting Fig. 1 (a)) of circuit board 3, be welded on subsequently on the circuit board 3, connect the AC power signal that terminal 412 accepted and reach circuit board 3 so that connect terminal 411, second with first.433 of ground connection pins extend upward and bending after smooth in body end face 403 be electrically connected so that utilize access area (not shown) on an electric wire (not shown) and the circuit board 3 to form, to reach the ground connection effect.

Adopt the shortcoming of above-mentioned AC joint as follows:

(1) first conducting pin 431, second conducting pin 432 are to extend downwards to be inserted in the pin hole 31,32 of circuit board 3, so pin hole 31 must cooperate the distance of 432 of first conducting pin 431 and second conducting pins to design with the distance in 32 in pin hole, so unfavorable this AC plug is inserted to the circuit board in all size.

(2) because first conducting pin 431 and second conducting pin 432 are metal material, and after directly being inserted in pin hole 31,32 vertically downward, row is welded on the circuit board 3 again, therefore, tool is not flexible for first conducting pin 431 and second conducting pin 432, can't eliminate part because the thermal stress that the electronic component 30 on the circuit board 3 produces makes the scolder of weld come off easily in operation.

Embodiment

Please see Figure 3 (a) reaches (b), AC joint 5 of the present invention comprises insulating body 50, body interior is established through hole 51, having first in the through hole 51 connects terminal 511, second and connects terminal 512 and earth terminal 513, first connects terminal 511, second connects the aperture (not shown) of terminal 512 and earth terminal 513 by body dorsal part 501, and is connected bonding pad 521,522 and 523 with first conducting pin 531, second conducting pin 532 and ground connection pin 533 respectively with the riveted joint mode.

Body bottom 502 also integrally formed two poles 54 are in order to plant to the circuit board in the corresponding jack.The structure of relevant pole 54 and ground connection pin 533 and principle are known by being familiar with present technique field person, do not give unnecessary details at this.

The invention is characterized in, the structure of first conducting pin 531, second conducting pin 532 is different with known technology, for example its be extend upward after the length crooked, and (do not show with an electric wire 55 and circuit board, the operation principle of circuit board of the present invention and configuration also are known, do not give unnecessary details at this) the formation electrical connection; Moreover body 50 tops further are provided with a prominent plate 503 corresponding to the position of pad, to reduce the chance that pad exposes.

Fig. 4 (a) to (c) display application is in the coiling situation of the conducting pin of AC joint design of the present invention.With first conducting pin 531 is example, and in Fig. 4 (a), first conducting pin 531 mainly has aperture 5311, perforation 5312 and winding region 5313.Wherein aperture 5311 links to each other in order to the aperture (not shown) corresponding with body dorsal part 501, connects terminal 511 so that rivet first; On the whole winding region 5313 becomes T shape.The bare terminal end 551 that then makes electric wire 55 is by perforation 5312 (being preferably SI semi-insulation cover 552 also by boring a hole 5312 to provide better flexible) and further be wound in winding region 5313 (at Fig. 4 (b)); At last, apply scolder 554 in bare terminal end 551 spot welding steps, this moment, bare terminal end 551 can be positioned on the winding region 5313 effectively.Certainly, the other end 553 of electric wire 55 can further be inserted in the pin hole (not shown) of corresponding region on the circuit board or directly be welded on the circuit board.

In sum, the design of the conducting pin that AC joint design of the present invention is special is to utilize electric wire 55 to form with circuit board to be electrically connected, and compared to known technology, has the following advantages:

(1) conducting pin in the known technology the 431, the 432nd, extend downwards be inserted in circuit board 3 hole 31,32 in, so pin hole 31 and the distance in 32 in pin hole must cooperate in advance framework to finish; And the present invention utilizes electric wire 55 and circuit board to form the mode that is electrically connected, applicable various pin pitch-row from circuit board or do not need the circuit board (other end 553 of electric wire 55 can directly be welded on the circuit board) in pin hole, be applied to the flexibility of the circuit board of all size so improve it.

(2) because electric wire 55 has bigger flexiblely, can effectively eliminate because thermal stress and the mechanical stress that the electronic component 30 on the circuit board 3 produces in operation, the scolder of weld is not vulnerable to thermal stress and mechanical stress influence and comes off.

(3) conducting pin 531,532 distinctive perforation 5312 of the present invention and winding region 5313 are configured with and help promote welding effect, and bare terminal end 551 is located effectively.

Therefore, AC joint design of the present invention can be avoided the shortcoming in the known technology.

The present invention can, appoint and executes that the craftsman thinks and be to modify the scope of right neither disengaging appended claims as all by being familiar with present technique person.
