A kind of integral type power supply adaptor

Technical field

The utility model is related to electric accessories technical field, and in particular to a kind of integral type power supply adaptor.

Background technology

Power supply adaptor is a kind of power conversion device, and it is re-reading that it is matched in phone composite aircraft, game machine, language extensively In the equipment such as machine, notebook.

Power supply adaptor is main to be made up of shell, power transformer, rectification circuit and the DC lines being connected with rectification circuit. In the prior art, the package assembly of power supply adaptor is：Shell is divided into the upper shell and lower house for mutually covering, and upper shell is with The line that covers of housing is provided with bayonet socket for clamping DC lines, DC lines by bayonet socket clamping so as to be fixed with shell, and then and shell Interior rectification circuit electrical connection.

However, the package assembly Shortcomings part of above-mentioned power supply adaptor, first：It is divided into the shell of upper and lower casing, even Firmness deficiency is connect, and the line that covers of upper and lower casing influences the overall appearance of power supply adaptor；Second：Due to the chi of bayonet socket It is very little need it is bigger than the size of DC line DC is injected bayonet socket, therefore easily cause DC lines and slip into shell or skidded off from shell, no Beneficial to the stability of power supply adaptor；3rd：, it is necessary to DC lines are accurately placed at one of housing during assembling, then by another Outer housing alignment compression could assemble DC lines and housing, and so not only each part is directed at assembling by labor intensive, and It is unfavorable for rapidly assembling.

The content of the invention

There is above-mentioned technical problem for prior art, the utility model provides a kind of firmness electricity high, easy to assembly Source adapter.

To achieve the above object, the utility model provides following technical scheme：

Integral type power supply adaptor is provided, it is characterized in that：Including shell, the entrance being opened on the shell and described The DC lines of entrance grafting, the one end of the DC lines is provided with locked groove, and the inwall of the shell is provided with lock, and the locked groove is from institute State entrance into shell and with the lock snapping, the DC lines are provided with for stopping that wire body slips into the spacing of shell inner cavity Part, the size of the size more than the entrance of the locating part.

Preferably, the locked groove includes two group of bumps, and two group of bumps are symmetrically fixed on the DC lines outside, and each is convex Block group includes two projections, and described two projection interval settings are forming caulking groove.

Preferably, the lock includes two bent bucklings, and two bent bucklings are symmetrically set in the both sides of the entrance, the folding One end of curved button is respectively formed the button tongue for snapping onto the caulking groove, and the spacing of the button tongue of described two bent bucklings is more than institute State DC lines diameter and the length less than the DC lines and two group of bumps for being individually fixed in DC lines both sides and.

Preferably, the entrance is strip shape gob, and the length direction of the bar hole is vertical with the snapping direction of the lock.

Preferably, the locating part is connected with the locked groove and the length direction along the DC lines sets gradually.

Preferably, the locating part is to be centered around the bulge loop on the outside of the DC lines.

The beneficial effects of the utility model：

A kind of integral type power supply adaptor of the present utility model, including shell, are opened in the entrance on shell, and with enter The DC lines of mouthful grafting, the one end of DC lines is provided with locked groove, and the inwall of shell be provided with can with the lock of locked groove snapping, during assembling, DC line ends with locked groove are entered from entrance the inner chamber of shell, when locked groove enters the inner chamber of shell and reaches lock position, led to Assembling is crossed to be capable of achieving and lock snapping, and then so that shell and the linear integrated structures of DC；Also set up in the wire body of DC lines Finite place piece, the size of the locating part more than entrance size, when locating part reaches entrance, due to locating part size be more than into Mouth size, locating part is blocked in outside entrance, and then prevents wire body from sliding further into shell inner cavity, maintains DC lines with shell Fixed position.Compared with prior art, power supply adaptor of the present utility model has the structure of integral type, it is to avoid due to covering The whole machine that line causes waves the problem easily sent, and enhances the firmness of power supply adaptor, in addition, it is only necessary to enter DC lines reeve shell Row snapping sets the assembling that can complete DC lines and shell, and not only degree of being connected firmly is good, and easy to assembly quick, using raising Production efficiency.

Specific embodiment

The utility model is described in detail below in conjunction with specific embodiment and accompanying drawing.

A kind of integral type power supply adaptor of the present embodiment, as shown in figure 1, including shell 1, shell 1 offers entrance 2, The inwall of shell 1 is provided with lock 5, and the one end of DC lines 3 is provided with locked groove 4, and the DC line ends with locked groove 4 enter shell 1 from entrance 2 And set with realizing that DC lines 1 are assembled with shell 2 with 5 snappings of lock, it is specifically, firm with the snapping of lock 5 to improve locked groove 4 Degree, the structure of locked groove 4 is to include two group of bumps, and two group of bumps are symmetrically fixed on the outside of DC lines 3, and each group of bumps is divided into two again Individual projection 41, so as to form caulking groove 42, caulking groove 42 is used for and latches 5 snappings two interval settings of projection 41, further, lock 5 structures are as shown in figure 3, be to include two bent bucklings, two bent bucklings are symmetrically set in the both sides of entrance 2, two the one of bent buckling Used as button tongue, button tongue insertion caulking groove 42 is to be capable of achieving locked groove 4 to be set with the snapping of lock 5 for individual end, wherein, between two button tongues Away from the diameter more than DC lines 3 to cause that DC lines are passed through, meanwhile, two button tongues are smaller than DC lines 3 and are individually fixed in DC lines 3 The length sum of two group of bumps of both sides is snapped onto on tongue with the caulking groove 42 for enabling locked groove 4.DC lines 3 be additionally provided with for Stop that wire body slips into the locating part 6 of the inner chamber of shell 1, the size of the size more than entrance 2 of locating part 6 is further to limit DC lines 3 Slip into shell 1.Entrance 2 is set to strip shape gob, to adapt to the length sum of DC lines 3 and two projections of its both sides, and then causes DC Line can smoothly enter shell, and the width of strip shape gob is little, be easy to and locating part constitutes spacing relation.Further, it is spacing Part 6 is connected with locked groove 4 and the length direction along DC lines 3 sets gradually so that DC lines are only that locked groove 4 enters shell, it is preferable that limit Position part 6 is the bulge loop for being centered around the outside of DC lines 3, and bulge loop easily can constitute spacing relation with entrance 2.

Finally it should be noted that above example is only used to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected scope, although being explained to the utility model with reference to preferred embodiment, this area it is general It is logical it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent, without deviating from this The spirit and scope of utility model technical scheme.
