Description
Technical field
The utility model belongs to electric equipment production technical field, and in particular to the cord grip structure of input line is improved.
Background technique
Most electrical equipment has exposed input line currently on the market, and exposed input line is unavoidable to bear significantly
Slight pulling force.Therefore, in the design requirement of this kind of equipment, can all there are pulling tension requirements to input line, i.e. input line is bearing certain
In one pulling force stipulated time, there is not allowed that displacement, and line skin cannot be damaged.
For this installation requirement, the problem of existing common solution, is as follows：
1. increase a PC crimping lid, withstand input line with the rib on the inside of crimping lid, with two screw lockings to its
His structural member.This method has many drawbacks, first of all, it is necessary to high mold expense is born, and in mass production, the material of PC
Expense also can not look down upon.Secondly it is loaded onto group, since input line is harder, and wants that compressing input line must have very big deformation quantity,
Keep assembly difficulty larger.Furthermore in face of great pulling tension requirements (>When 80N), it is easy to crush the line in line skin or crimping lid
Rib is easy to appear deformation, and recess can not reach safety requirement.Finally, in appearance, crimping lid often seems very lofty,
Influence the globality of product.
2. input line is pierced by from aperture again in inside knotting.This scheme is relatively common on lamps and lanterns product, in fact in itself
With regard to unreliable.The bending of input line wide-angle is wound, and necessarily increases itself burden, or even be easy to appear input line and be directly torn
The case where.It is loaded onto group, is all manual operations due to knotting, also not can guarantee node size, position unification.And input line is general
Harder all in 2.0mm or more, knotting difficulty is big.It is finally embodied on whole lamp, is exactly that input line is different in size, it is elastic different, it shows
It is very cheap, not firm to obtain.
3. I-shaped rubber sleeve is fixed in input line, rubber sleeve is allowed to fix with structural member.There is outsourcing for very thick
The power supply line of insulated hull, this method is really very practical, but just seems on mini electrical equipment and extremely limit to.On the one hand, more carefully
The fixed difficulty of input line rubber sleeve it is big, on the other hand, it requires to make compromise on structural member, for example needs to cut a guiding
Slot, in order to the installation of rubber sleeve.
Utility model content
Utility model aims to solve the problems in existing, a kind of pressure of electrical equipment input line stretching resistance is provided
Cable architecture.
To reach above-mentioned purpose, the utility model adopts the following technical solution.
A kind of pressuring line structure of electrical equipment input line stretching resistance, the pressuring line structure are arranged in wire box, the crimping knot
Structure includes the first limiting slot and the second limit hole being formed on the same side wall of wire box；Wherein, the first limiting slot, it is online to be formed
Stringing slot in box one side wall, the stringing slot are formed on the inner edge surface of the side wall；Second limit hole, to be formed on the side wall
Cable-through hole, which corresponds to stringing slot and is formed in the rim surface of the side wall；Input line in wire box is first pressed on stringing
In slot, afterwards around cable-through hole to stretch out wire box.
Preferably, the stringing slot is made of the arc-shaped left and right block edge being integrally formed on side wall, the left and right block edge
Between form otch；The stringing slot is arranged higher than cable-through hole；The input line being pressed in stringing slot passes through cable-through hole around 90 °
To stretch out wire box.
Preferably, the stringing slot is made of the briquetting being integrally formed on side wall, which is kept off by a flange part and one
Stop is integrally formed, and the flange part is integrally formed on side wall, and the stringing slot is separated into left and right stringing slot；The left side,
Right stringing slot is two parallel vertical slots, can be symmetrical two skewed slots；The input line being pressed in stringing slot passes through around 90 °
Cable-through hole is to stretch out wire box.
Compared to the prior art, technical solution provided by the utility model has the advantages that：
1. the input line in the utility model wire box is first pressed in the stringing slot in the first limit stage, rear around the second limit
The cable-through hole in position stage is to stretch out wire box.Very big pulling tension requirements can be reached, and safe and reliable.After tested, the lamp of shipment North America
Has product, according to UL1598 standard, outer lines need to be required by the tensile test of " single input line 89N, one minute ".It is using
The input line of diameter 2.8mm survey the utility model pressuring line structure can perfection pass through, this be existing structure pressure-ray film without
What method was accomplished.In addition, input line is not compressed with sharp rib, even if bearing pulling force beyond requirement, also hardly occur
The situation of line skin breakage, also can utmostly reduce electric shock risk in special circumstances.
2. being correspondingly arranged at the external sky that the same side wall of wire box tightens wire casing and cable-through hole is not take up internal drive and outlet
Between.Drive part first, as long as guaranteeing input line nearby without higher electronic component.This point, no matter in isolation drive
Or it is all very easy to realize in non-isolated driving, this is it is ensured that drive part can save space with characteristics of compact layout.Outlet
Position does not have redundant structure, it appears that seems clean and tidy, beautiful yet.
3. traditional crimping method requires undoubtedly to will increase many costs by the structural member of a special crimping, packet
Include die cost, Master Cost, assembling labour cost.And the utility model pressuring line structure is integrally formed on wire box side wall
, cost is substantially reduced.
4. the utility model input line is to be pressed to be pierced by inside wire box, do not need by any tooling, the several seconds can
To complete.Simple installation reduces working hour.
5. the utility model stringing slot at least there are three types of design structure, preferably be suitable for a variety of installation operating conditions, dress
With more efficient.
