Description

The double insulating structure that power supply line is connect with primary line packet

Technical field:

The utility model relates to technical field of electronic products more particularly to power supply, charger etc., refer in particular to a kind of power supply line with The double insulating structure of primary line packet connection.

Background technique:

Some type of electric equipment products, it is exhausted that input electrical body to ground metal portion must have dual (two kinds) before Edge protection, Normal practice is that power supply line is split into eight suffixes, and eight suffixes need power supply line crust removing 30mm or so, is existed in this way Just only one layer of insulation within the scope of 30mm, after being wired to fiery ox, single layer dielectrics part is to encounter metallic ground Part, this, which will lead to, does not meet safety and electric leakage (can lead to risk of shock), so having to twine in its single layer dielectrics part Can be only achieved the effect of double insulation around insulating tape, such structure increases production process, take expect it is time-consuming, and After increasing adhesive tape, still there is part jointing tape place that can expose to transformer wire packet region, form difference with original cable outer layer It is different, cause product whole unsightly.

Utility model content:

The purpose of the utility model is to overcome the above-mentioned shortcoming of present product, a kind of power supply line and transformer are provided The double insulating structure of primary line packet connection.

The utility model realize its purpose the technical solution adopted is that: what a kind of power supply line was connect with primary line packet Double insulating structure, power supply line include two conducting wires being made of respectively insulation endodermis and core and are coated on two conducting wires Periphery insulation sheath layer, it is characterised in that: at one end that power supply line connect with primary line packet, insulate endodermis with Core exposes to insulation sheath layer end, and core end exposes to insulation endodermis end, i.e. tail is opened in insulation sheath layer formation Portion and insulation sheath layer end face at a distance from core end≤13mm；The end of two conducting wires is in toed-out shape, and two lines core Minimum range between exposed parts is greater than 5mm；It is wired in the join domain covering of power cord ends and primary line packet Packet insulating layer, line packet insulating layer are completely covered insulation endodermis and cover insulation sheath layer end.

As a kind of preferred embodiment, the distance that the power cord ends open tail portion is 12mm, i.e. insulation sheath layer end Face is 12mm at a distance from core end, and the length of the insulation sheath layer end covered by line packet insulating layer is 2-5mm.

The utility model using the above structure, shortens power supply line and opens tail length degree, ensuring have with transformer In the case where enough stub connections, reduce the length in single layer dielectrics region, and just can be in primary line packet Reach coverage effect using line packet insulating layer in region, can reach double insulation effect in the case where in addition not increasing adhesive tape Fruit, and line packet insulating layer can also cover the partial region of the insulation sheath layer of power supply line, avoid inner lead exposed, to make Product appearance is more aesthetically pleasing.

Detailed description of the invention:

Fig. 1 is a kind of planar structure schematic diagram of embodiment of the utility model.

Specific embodiment:

The present invention will be further described with attached drawing combined with specific embodiments below.

As shown in Figure 1, the double insulation knot that a kind of power supply line described in the utility model is connect with primary line packet Structure, power supply line 1 include two conducting wires being made of respectively insulation endodermis 11 and core 12 and are coated on two conducting wire peripheries Insulation sheath layer 13, in which: at one end that power supply line 1 is connect with primary line packet, insulate endodermis 11 and core 12 expose to 13 end of insulation sheath layer, and 12 end of core exposes to insulation 11 end of endodermis, i.e. 13 shape of insulation sheath layer At open tail portion and 13 end face of insulation sheath layer at a distance from 12 end of core≤13mm；The end of two conducting wires is in toed-out shape, And the minimum range between 12 exposed parts of two lines core is greater than 5mm；Connection in 1 end of power supply line and primary line packet The wired packet insulating layer 2 of region overlay, line packet insulating layer 2 are completely covered insulation endodermis 11 and cover 13 end of insulation sheath layer Portion.

As a kind of preferred embodiment, the distance that tail portion is opened in 1 end of power supply line is 12mm, i.e. insulation sheath layer 13 End face is 12mm at a distance from 12 end of core, and 13 tip lengths of insulation sheath layer covered by line packet insulating layer 2 are 2- 5mm。

When connection, first two the end of a thread of power supply line 1 are connected and fixed with primary line packet respectively, then to cover line packet exhausted Edge layer 2.Therefore the assembling steps of the utility model are very easy, and production efficiency can be improved and save adhesive tape materials, reduce Cost improves the market competitiveness of enterprise.

In conclusion the utility model is using the above structure, shortens power supply line and open tail length degree, is ensuring and primary In the case that coil has the connection of enough stubs, reduce the length in single layer dielectrics region, and just can be in transformer Reach coverage effect using line packet insulating layer in primary line packet region, can reach in the case where in addition not increasing adhesive tape dual Insulation effect, and line packet insulating layer can also cover the partial region of the insulation sheath layer of power supply line, avoid inner lead exposed, To keep product appearance more aesthetically pleasing.In addition, the minimum range of wire termination the end of a thread is greater than 5mm in the utility model, there is foot Enough safe distances are that power supply product security performance also improves.
