Description
Technical field
The utility model is related to electrical connection arts, and in particular to the electricity for protecting connector between connection terminal and cable
Connect protection mechanism.
Background technology
Electrical connection be allow electric current by any structure.Between each inside electric appliance and each electrical equipment
There is electrical connection, but most of electrical connection design is all more single.In order to realize electrical connection, the usually electricity with special end
Cable extends between two connectors；These ends will be interlocked with the end of compatible cable to allow to carry out power transmission.
Most common electrical connection is interlocking cable.This electrical connection form have various sizes and configuration, cover from greatly to
Various forms small, from simple to complexity, therefore application is extremely wide.This type of attachment is transmitted electric current using a cable
Terminal on to line end.The terminal has special designing to allow it to be inserted into another device, and establishes connection.This electricity
The power cord that most common form is most of electrical equipments is connected, but other common examples further include earphone jack and lamp
Seat.
Other than this interlocking cable, also have inside equipment and in the wiring of complication system (such as house and automobile)
Other two kinds basic connections：It is threadedly coupled and crimps system.It is by an exposed special end of electric line or belt to be wherein threadedly coupled
The electric wire in portion is put into threaded hole.Screw together with wire intertwist and is simply threaded into hole, in electric wire and screw or
Almost inseparable connection is formed between person's shell.This connection can almost ensure safety under any circumstance, therefore logical
It is commonly used in high vibration or the equipment of other mal-conditions.
Crimping system is designed to compress each strands to a certain extent together so that do not interspace between strands (
Gap).This prevents moisture and oxygen from entering pressure contact portion, to prevent to corrode.If correct implement, after pressure contact portion
Portion carries out the corrosion resistance that welding will not affect that connector, because without the enterable space of solder.Finally, the mesh of process is crimped
Be so that conducting wire is deformed and be crimped onto scheduled level, to eliminate space and by conducting wire cold working to scheduled level.Such as Fig. 1 institutes
Show.
In some have the extreme environment substantially vibrated for a long time, for example, wind-power electricity generation, solar power generation, height
Fast train/subway etc., when terminal is fastened on hubcap, the end of terminal and power cord is in hinged joint state, such as Fig. 2
It is shown.In fig. 2, cable 10 is connected to connection terminal 20.One end of connection terminal 20 is in flat, with for example, by installing spiral shell
Nail 30 is connected to the hubcap 50 of the axis 40 of the electrical equipment such as train, and the other end is in a tubular form, is inserted into current supply cable 10
And it is crimped.Cable is in suspension bridge state at this time.When amplitude is big, cable can be scraped with terminal pipe, and cable is caused to be bent
Clothes.With the accumulation of surrender number, cable will will disconnect, and power transmission will interrupt.
Therefore, this field needs a kind of structure that can be protected to the connector between terminal and cable, it can be ensured that
The safety being electrically connected between terminal and cable.
