Description

Cylinder adapter is worn in a kind of high temperature resistant grease proofing anti-vibration of truck

Technical field

This utility model relates to Diesel engine wire harness, gearbox wiring harness technical field, particularly relates to a kind of card Car is high temperature resistant, and cylinder adapter is worn in grease proofing anti-vibration.

Background technology

At diesel engine realm, along with emission request increasingly stringent, major part oil spout in following state five, state six diesel engine Device is mounted in inside engine bonnet, by wire and adapter (being commonly called as wearing cylinder adapter) and engine cylinder external body ECU is connected, thus controls fuel injector action.When the engine is running, oil temperature is at a relatively high, creates again splashing, shakes simultaneously Dynamic acceleration is the biggest, therefore wears the cylinder adapter carrier as inside and outside connection, the condition very severe of work, it is necessary to resistance to height Warm, grease proofing, anti-vibration, corrosion-resistant, under the working condition severe at this, to wear cylinder adapter extremely difficult in design.

At present, cylinder adapter of wearing the most universal on market is made up of terminal fixed block, connector shell, sealing ring, end Sub-fixed block uses external structure, needs independently installed.In addition connector shell also needs to quadric injection mould fluid sealant inside it.Its Shortcoming is that terminal fixed block need to be separately installed, and operation inconvenience affects outward appearance.Connector sealing structure needs quadric injection mould, and technique is multiple Miscellaneous, mould is complicated, and percent defective is high, also can bring additional processing cost, has produced though existing and applied, but this adapter exists Many deficiencies, are mainly manifested in:

1., terminal fixed block external, need separately installed, operation inconvenience: connector shell and fixed mount are respectively provided with through hole, dress

During joining, terminal guide and limit is inconspicuous, when assembling it is noted that locking mechanism assembles the situation that puts in place, its structure Complexity causes the time-consuming sweat of assembling process, assembling process difficulty, and product be easily damaged, and assembling fastening puts in place situation There is hidden danger.

2., connector shell carry out after mold developing be molded production and processing, connector sealing structure need to be at half product base Quadric injection mould fluid sealant on plinth, secondary injection adhesive process is complicated, and mould is the most complicated, and percent defective is high, causes processing cost high.

3., existing adapter utilize space mostly to be 14 holes identical, position, hole is few, it is impossible to meet the demand of additional loops, Range of application reduces.Limit upgrading.

4., bonder terminal be only provided with and once lock, thus cause terminal pulling-out force little, connection reliability is poor.

5., adapter use non-standard machining solid terminal, processing difficulties, the connection of electric wire and solid terminal makes Be manual crimp technique, can only single process during crimping, it is impossible to realize semi-automatic, fully-automatic production.

Summary of the invention

For the present situation of above-mentioned prior art, the purpose of this utility model is to provide a kind of simple in construction, assembling fastening, side Just operate, possess high reliability, cylinder adapter is worn in the high temperature resistant grease proofing anti-vibration of multipurpose truck that range is broad.

This utility model be the technical scheme is that cylinder adapter is worn in a kind of high temperature resistant grease proofing anti-vibration of truck, and this is even Connect device and include connector body, sealing ring, secondary lock, terminal and sealing-plug, the shell on described connector body and being arranged on Terminal fixed block in shell is integral type version, and on the terminal fixed block of described connector body, symmetry is laid with ten Six terminal connections holes, wherein two terminal connections holes below are terminal connections preformed hole；Described secondary lock is assemblied in connection The inside of device body is to increase terminal pulling-out force；The section of described sealing ring uses " mountain " character form structure, is sleeved on adapter To reach sealing effectiveness on body；Described terminal is plugged in terminal connections hole, and the wire link position of described terminal is provided with close Blocking, described sealing-plug uses two-way interference and combines the design of ripple glaze thus reach positive confinement.

This utility model has the following advantages and beneficial effect:

1, this utility model eliminates terminal fixed block, i.e. connector body and the most once locks with terminal bodies, assembling Process simple and fast.Solve because of time, the waste of strength during assembling；Solve the loss brought because of assembling.

2, this utility model wire seals and uses independent sealed plug, and technique is simple and reliable compared with quadric injection mould, and mould is also simple, Less investment, percent defective is low.In other common wire harness fields, high-volume uses this structure, and can realize semi-automation production.

3, this utility model is in equal space, and position, hole is designed to 16 holes, increases too many by two hole, namely increases one Individual loop, can add a load, provides more loop, make adapter make when increasing the kinetic energy such as exhaust brake at electromotor Become broader by scope, convenient product up-gradation later.

4, this utility model connector body and terminal bodies are the most once locked, and use two in wearing cylinder adapter first The application of the structure of secondary lock, secondary is locked in the work also acting as second time locking terminal with terminal after connector body is once locked With, secondary lock also has the function of detection automatically simultaneously, and the application of this secondary lock makes twice locking of terminal, terminal and adapter Coordinate safer, reliably, make terminal pulling-out force double above.

5, this utility model sealing ring and the grease proofing resistant to elevated temperatures fluorine silica gel raw material of sealing-plug materials'use produce, and prevent Having, oil and temperature are too high and cause adapter to lose efficacy, and meet and normally use under having oil, high-temperature condition, also increase it and use the longevity Life.

6, the terminal of the connection of this utility model adapter uses universal chain stamped terminals, the connection edge of terminal and electric wire With conventional crimping techniques, can be selected for semi-automatic crimping apparatus or full-automatic crimping apparatus, the course of processing is safe and reliable, it is simple to large quantities of Amount production operation, also greatly enhances production efficiency simultaneously.
