Description
Technical field
The present invention relates to electric connector fields, more particularly, to a kind of electric connector contact structure.
Background technique
Electric connector contact structure type one type is plug-in type, and resilient contact is packed into jack.Elastic connecting
Contact element is by band punching press winding shaping, and structure, which can be, to be preced with spring, turns spring, torsional spring etc., and there are a minimums in the middle part of resilient contact
Diameter, that is, larynx neck.When plug and socket to it is slotting when, contact pin, resilient contact, jack matrix are bonded and realize that Elastic Contact connects.
Electric current, through resilient contact throat, is transferred to resilient contact both ends to jack matrix, completes electric current transmitting by contact pin.
For existing connector generally there are two types of structure, a kind of structure, which is utilized on jack matrix inner wall, is arranged groove,
Cup spring structure is provided in groove, second of structure, which is utilized in jack matrix, turns spring, two kinds of structures along axis setting
Partial properties requirement can be met at present, and be widely used.But both structures are after electrical connection at present, when electric current stream
Cross it is former so there are technological deficiencies, such as: cup spring structure plugging hole component is likely to occur spring silk in swapping process and pulls, becomes
The damage such as shape, fracture, may result in Joint failure when serious.Turn spring structure plugging hole component when loading high current, temperature rise is super
Height, properties of product are unable to reach customer requirement.In current new-energy automobile charging gun series volume production product, use it is this kind of
Structure there is above-mentioned problem, bring security risk to using.
Summary of the invention
The purpose of the present invention is on the basis of existing technology, designing a kind of new plugging hole component structure, connector is realized
Temperature rise is effectively reduced in contact carrying more high current.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of electric connector contact structure, the first elastic connection being arranged including jack matrix and in jack matrix along axis
Part is provided with the second flexible connector of closed loop on the jack matrix inner wall, and first flexible connector is after stress
It is connect with the second flexible connector in non axial upper reliable contacts.
In the above-mentioned technical solutions, first flexible connector include two connecting pins and be connected to two connecting pins it
Between several elastomers.
In the above-mentioned technical solutions, at rolled behind several elastomer connections connecting pin.
In the above-mentioned technical solutions, the second flexible connector ring set is on the first flexible connector and in jack matrix
Wall connects.
In the above-mentioned technical solutions, it is provided with along non axial for the second elasticity to be arranged on the jack matrix inner wall
The annular groove of connector, the second flexible connector are arranged in annular groove, and first company's flexible connector is inserted through the second elastic connection
Part.
In the above-mentioned technical solutions, the annular groove of the receptacle body inner wall is no less than one, is provided in each annular groove
Independent second flexible connector.
In the above-mentioned technical solutions, the jack matrix inner wall is hydraulically smooth surface, and the second flexible connector ring set is the
On one flexible connector.
In the above-mentioned technical solutions, described first flexible connector exterior ring cap, one the second flexible connector, the second elasticity
The center of rolled is arranged in connector.
The operation principle of the present invention is that: the first flexible connector is limited in jack matrix, when contact pin be inserted into jack matrix,
By the normal pressure in pin diameter direction, the first flexible connector occurs flexible deformation larynx neck and becomes larger and will just first flexible connector
Pressure is transferred to the second flexible connector.Second flexible connector is mounted between flexible connector and jack matrix, the second bullet
Property connector have very strong elasticity, when by the first flexible connector normal pressure, the second flexible connector also and then compress
First flexible connector, contact area increase, and conductibility increases, and temperature rise is also with reduction.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
The present invention increases annular groove in jack matrix, and the quantity of annular groove is determined by factors such as product structure size and size of current.
It is first packed into cup spring (the second flexible connector) in jack matrix when assembly and is packed into the first flexible connector afterwards, by original one
Flexible connector becomes a flexible connector and adds one or more cup springs.When plug and socket to it is slotting when, contact pin, Elastic Contact
Part, cup spring, jack matrix are bonded and realize elastic connection.Electric current, through resilient contact throat, is transferred to elastic connecting by contact pin
To jack matrix, increased shunt circuit is resilient contact throat through cup spring to jack matrix at contact element both ends, completes electric current and passes
It passs.Shunt circuit is increased in the program, electric current is allowed to be shunted, to reduce temperature rise, improves electric property.
