Specific embodiment

In order to make those skilled in the art better understand the scheme of the utility model, combined with specific embodiments below into one Step illustrates the technical solution of the utility model.

Embodiment one

A kind of power distribution unit of the utility model, i.e. power outlet include front panel 40 and the front panel spiral shell Follow closely the sleeve seat 41 being fixedly connected, the sleeve seat side be set and is fixedly connected with the front panel, such as grafting or The USB module 42 that the modes such as welding are fixedly connected, and the rear shell 1 being fixedly connected with the front panel, the rear shell packet Three sides 10,11,12 and a top surface 20 of perpendicular arrangement are included, three sides constitute the U-shaped of front opening 30, It is provided with the line outlet groove 21 of open front on the top surface 20, multiple heat release holes 24 are provided on the top surface.I.e. with three Before the U-shaped open side that side is constituted is, while being upper with three sides top surface connected vertically, otherwise is bottom, with Lower description is all as benchmark, it is emphasized that, explanation is made only to facilitate understanding at this, not to the utility model Any limitation of protection structure.

Wherein, for convenient for fixation, the side bottom opposite with front opening is formed at least two protruding portions towards outside Grab 13.Card slot 43 corresponding with the grab is provided on the front panel 40, on the grab and front panel Corresponding card slot matches, it can be achieved that quickly just positioning, in order to subsequent fixed installation.Of course, it is possible to using inwardly or Person realizes that clamping is positioned towards the grab of two sides.Moreover, being also not limited to grab, the hole on card column and front panel also can be used The modes such as interference fit.

Meanwhile the top surface is fixedly connected with the sleeve seat respectively in line outlet groove two sides, specifically, described It is formed with connecting cavity 26 with integrally extending downwardly on top surface, is formed with corresponding internal threaded column on the sleeve seat 46, the top surface is fixedly connected by the screw across the connecting cavity with sleeve seat.

Utilize connecting cavity and sink to the fixation that screw in connecting cavity realizes top surface, it is ensured that top surface it is smooth, after being convenient for Continuous assembly, and the internal threaded column by being made into integration on sleeve seat is fixed while playing support effect, effectively improves top Intensity at the especially line outlet groove two sides of face, improves the assembly effect of socket, meets the assembly methods such as inlay card.

Further, the internal threaded column at least upper end can match the insertion connecting cavity bottom, from connecting cavity The top surface is fixedly connected by the screw across the connection sheet with sleeve seat.Connecting cavity is firstly inserted into using internal threaded column Design, provide convenience for subsequent screw of beating.It is preferred that the internal threaded column is that only upper end can match variable diameter in insertion connecting cavity Design is to further increase support positioning and be connected and fixed effect.

It meanwhile further including the front apron 31 constructed at 30 end of U-shaped opening, the front apron and the side 11,12 and top surface 20 it is integrally formed.The design of monosymmetric front apron, can effectively increase the integral strength of rear shell, and into one Step prevents the end of a thread of power supply line from deviating from.Meanwhile the design that the front apron is in contact with the lateral surface of sleeve seat, it can be improved whole The locating speed of body realizes that rear end grab is fixed, central screw connection, a variety of fixed forms combination of front front apron positioning, While realizing quick assembly, guarantee structure design strength.

Further, it is the bonding strength for improving two sides 11,12 avris portions, increases non-deformability, the side On be formed with support bar 16, preferably the support bar is located at connecting cavity front and rear sides, with the sleeve seat upper surface or Front surface is inconsistent, play the role of installation after press sleeve seat 41, while between the side of sleeve seat formed positioning slope surface with The inner supporting type positioning for realizing two sides 11,12, for the region of insufficient space, in sleeve seat portion corresponding with the support bar It is formed with evacuation 44.

Embodiment two

To avoid the power supply line junction in installation or use process from being detached from, in the one of line outlet groove on the top surface Formed on side it is multiple, such as three U-shaped card wire casings 22, opening width matches with power supply line, such as more straight than the power supply line The small 1-2mm of diameter, to position firewire, ground wire and zero curve for distinguishing clamping, in this way, being avoided that when installation first because drawing Pulling causes power supply line and the connection of sleeve seat to loosen, moreover, being also avoided that power cord in use is straight from after sleeve seat It connects dangerous with other positions generation electrical contact generation electric shock etc..

It further, is the clamping effect for improving U-shaped card wire casing, the top surface inner surface is in the U-shaped card wire casing Place is provided with U-shaped enhancing muscle 23.Wherein, the U-shaped card wire casing is the opening diameter structure more smaller than inside diameter, or also C-type structure be can be designed as to prevent power cord from going out.

Embodiment three

Truncated rectangular pyramids shape boss corresponding with the USB module of the power distribution unit is additionally provided on the top surface 25, because the terminals of USB module are just at the top of it, by the way of string holes is arranged on top surface, using the boss 25 of evagination Interior empty avoiding construction, suitably increase the space of junction, under the premise of guaranteeing whole small size, part protrusion is effectively ensured Connecting line is not under compression, and the layout of power supply line is connected convenient for it, is reduced because connecting power supply line quarter bend caused by insufficient space It is bad caused by folding, and contact of the rear shell with USB module is more compact, reduces overall volume.It is set moreover, part is outstanding Meter is convenient for subsequent installation and positioning, improves assembling.

Moreover, be additionally provided with multiple peep holes on the table top of the boss, such as four peep holes are below boss The case where wiring position of USB module, this 4 holes can intuitively see two wiring positions from two sides so that assembling when The problems such as waiting crimping, revealing copper wire can be observed.

The spatially relative terms such as "upper", "lower", "left", "right" have been used in embodiment for ease of explanation, have been used for Relationship of the elements or features relative to another elements or features shown in explanatory diagram.It should be understood that in addition to figure Shown in except orientation, spatial terminology is intended to include the different direction of device in use or operation.For example, if in figure Device be squeezed, the element for being stated as being located at other elements or feature "lower" will be located into other elements or feature "upper". Therefore, exemplary term "lower" may include both upper and lower orientation.Device, which can be positioned in other ways, (to be rotated by 90 ° or position In other orientation), it can be interpreted accordingly used herein of the opposite explanation in space.

Moreover, the relational terms of such as " first " and " second " or the like are used merely to one with another with identical The component of title distinguishes, without necessarily requiring or implying between these components there are any this actual relationship or Sequentially.

Illustrative description has been done to the utility model above, it should explanation, in the core for not departing from the utility model In the case where the heart, it is any it is simple deformation, modification or other skilled in the art can not spend creative work etc. The protection scope of the utility model is each fallen with replacement.
