Description

The circuit board assemblies that speaker hole is cut

Technical field

The utility model is related to board design field more particularly to a kind of board designs that reverse side speaker hole is cut.

Background technology

Present printed circuit board is welded on circuit boards by the pin of element, and playing component, overlapped with circuit Technique effect, most common situation are that a component needs two jacks to be respectively welded, and could access circuit, if need Dismounting then needs to wipe soldering off or destroys pin, and the recycling rate of waterused for resulting in circuit board is low to heavens.

Utility model content

For this reason, it may be necessary to provide a kind of novel circuit board and component, circuit board in the prior art and component installation are solved not Enough convenient problems.

To achieve the above object, a kind of circuit board assemblies that speaker hole is cut, including circuit board, plug-in unit are inventor provided, Jack is provided on the circuit board, the jack is tubaeform, and jack is more than jack in front in the aperture of circuit board reverse side Aperture；The plug-in unit includes bottom surface, fixed link, and the plug-in unit bottom surface is more than the positive trepanning size of jack, the fixed link Jack, top and the bottom surface of fixed link can be passed through to fix, the bottom end of fixed link is additionally provided with barb；One end of the barb with The bottom end of fixed link is fixed, and the other end oblique plug-in unit bottom surface direction extends.

Preferably, the plug-in unit is resistance unit, capacitive element or inductance part.

Optionally, the other end of the barb is additionally provided with two level protrusion, and the two level protrusion is used to be inserted into plug-in unit and insert Kong Shiyu Socket walls are bonded.

Further, it is provided with conductor on the barb, printed circuit is provided in the Socket walls.

Be different from the prior art, above-mentioned technical proposal by reverse side design loudspeaker pass cut, the fixed link of plug-in unit and fall Hook can conveniently insert jack and fixation, while the small reverse side in speaker hole front is big, enables to the circuit board plug-in being inserted into It can easily extract.

Specific implementation mode

For the technology contents of technical solution, construction feature, the objects and the effects are described in detail, below in conjunction with specific reality It applies example and attached drawing is coordinated to be explained in detail.

Referring to Fig. 1, the present embodiment introduces a kind of circuit board assemblies that speaker hole is cut, including circuit board 1, plug-in unit 2, in figure Circuit board for, top be front, lower section is reverse side.Be provided with jack 12 on the circuit board, the jack be it is tubaeform, The penetrating circuit board of jack, jack are more than jack in positive aperture in the aperture of circuit board reverse side.It can clearly be seen in figure It arrives, the jack of circuit board is reverse V-shaped setting, can be made up of slanting cutting or hollow out.Continue in please see Figure, it is described to insert Part 2 includes bottom surface 21, fixed link 22, and top and the bottom surface of fixed link are fixed, and the plug-in unit bottom surface is more than the positive trepanning of jack Size so that bottom surface can be resisted against on jack, and plug-in unit passes through jack by fixed link, and the bottom end of fixed link is also associated with barb 23；One end of the barb and the bottom end of fixed link are fixed, and the other end oblique plug-in unit bottom surface direction extends.As shown in the figure, when Plug-in unit from circuit board front be inserted into jack when, be along barb direction be inserted into, barb be extruded after can smoothly from jack just Circuit board is inserted into face, and subsequent barb is no longer extruded expansion, to abut against jack inner wall, plays the effect of fixing pluge.For The function of circuit can be reached, the plug-in unit can be resistance unit, capacitive element or inductance part.Printed circuit can directly print To the position of default hollow out jack so that on the circuit board of the utility model, printed circuit is provided on the inner wall of jack.Together Sample in order to matched, be provided with conductor in the barb and fixed link of plug-in unit, conductor is used for and the circuit function member on plug-in unit Device is connected.When plug-in unit is inserted into jack, barb is resisted against jack inner wall as shown in fig. 1, and to only need, there are one insert Hole can be achieved with the conducting of circuit function component and circuit without soldering.

In preferred embodiment, barb quantity is four, and barb is symmetrically arranged using fixed link as symmetry axis around fixed link, Printed circuit in jack is also configured as being located directly opposite in jack inner wall (only need to normally print copperplate line in printed circuit Road, cut point just blocks circuit in online design road when speaker hole is cut).Conductor on adjacent barb connects same connect Foot, the conductor design in fixed link is two piece-root grafting feet, connect respectively with the conductor on two barbs, while also respectively on connector The both ends of function element.So that barb can touch printed circuit after being inserted into jack, at least meet such as resistance etc The function element for not having positive and negative access to require positive and negative anodes normally accesses circuit.Solves circuit element access in the prior art Circuit board the problem of excessively complexity needs soldering.

In other optional embodiments, as shown in Figure 1, the other end of the barb is additionally provided with two level protrusion 24, The two level protrusion is used to be bonded with Socket walls when plug-in unit is inserted into jack.In the embodiment of this optimization, two level protrusion Section is triangle, includes at least two inclined-planes, the direction on two inclined-planes is different, and function is also different.One inclined-plane is for being inserted into When play guiding function so that plug-in unit can smoothly enter into jack.Other faces with Socket walls for being bonded after such insertion so that When needing to extract, with the reduction of Socket walls internal diameter, the subtended angle of barb can also be compressed, and play the role of smoothly extracting jack.

It should be noted that although the various embodiments described above have been described herein, it is not intended to limit The scope of patent protection of the utility model.Therefore, the innovative idea based on the utility model carries out embodiment described herein Change and modification or equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, directly Or above technical scheme is used in other related technical areas indirectly, it is included in the protection model of the utility model patent Within enclosing.
