The technical solution of connector of the present invention is:
Scheme 1, connector, including shell and setting are in the intracorporal contact of shell, it is characterised in that: the contact includes conduction
Matrix, the conducting base have for mating contact press and the elastic top splenium of flexible deformation, in the elasticity top splenium
It is fixedly connected with the conducting contact being fixedly connected with conducting base, the conducting contact has for leading with mating contact
The contact surface of electrical connection, the conductivity of the conducting contact are higher than the conductivity of conducting base.
Scheme 2, on the basis of scheme 1, the conducting contact be block structure.
Scheme 3, on the basis of scheme 2, the elasticity top splenium is equipped with holding tank for accommodating conducting contact.
Scheme 4, on the basis of 1 ~ 3 any one of scheme, pass through edge between the conducting base and the conducting contact
One of embedding, rivet or weld is fixedly connected.
Scheme 5, on the basis of 1 ~ 3 any one of scheme, the conducting contact is fine copper material, and the conducting base is
Copper alloy material.
The beneficial effects of the present invention are: compared with the prior art, contact according to the present invention, by by original one
The contact split settings of body design are conducting base and conducting contact, and conducting contact is fixedly connected on conducting base
On, while the conductivity that conducting contact is arranged is higher than the conductivity of conducting base, can guarantee so in the actual work,
Since the performance of the high conductivity of conducting contact makes the contact resistance of the contact lower, and then contact hair can be reduced
Heat reduces contact temperature rise, to improve the through-current capability of connector.Meanwhile it can either be met using the form of split settings and be connect
The requirement of the elastic property of contact element also can satisfy the requirement of the low cost of contact, relatively simple for structure, and actual processing side
Just, there is certain versatility.

Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The embodiment 1 of contact of the invention, as shown in figure 3, the contact 1 in the embodiment is laminated structure, packet
Include conducting base 11, wherein one end of conducting base 11 is the terminals 112 for being conductively connected with cable, and the other end is to supply
Mating contact presses and the elastic top pressure side 111 of flexible deformation can occur, and in this present embodiment, which is that copper closes
Golden material is integrally formed, and conductivity with higher and stronger mechanical performance, yield strength are higher.
It is additionally provided with holding tank 113 in the elastic top pressure side 111 of above-mentioned contact 1, embedded with conduction in holding tank 113
Contact 12, conducting contact are block structure, and in the present embodiment, the elastic top pressure side 111 of the conducting base 11 is template
Structure, above-mentioned holding tank 113 are fixed on holding tank 113 along the plugging direction extension perpendicular to contact 1, conducting contact 12
It is interior, and be conductively connected with conducting base 11.In the present embodiment, conducting contact 12 be fine copper material formed, fine copper have than
The higher conductivity of copper alloy, and because the yield strength of fine copper is lower, so only being contacted by the realization of conducting contact 12 with adaptation
Conductive contact between part has contact surface 121 on conducting contact 12, by between conducting base 11 and conducting contact 12
Relatively fixed connection guarantee that contact 1 with higher can be led by conducting contact 12 in actual connection procedure
Electric rate, lower contact resistance reduce so as to meet biggish through-current capability, and generate heat.Pass through conducting base simultaneously
11 guarantee contacts 1 can have preferable mechanical performance, during this connect with mating contact, pass through elastic top splenium
Deformation realization contacted with the press of mating contact, guarantee conducting contact 12 and mating contact between being stably connected with.
Above-mentioned conducting contact 12 is fixed on matrix, is respectively formed and is fitted in the side plate face of conducting base 11 opposite to each other
The contact surface 121 of mating contacts connection, can guarantee can there is biggish contact between contact 1 and mating contact in this way
Area while guaranteeing through-current capability, improves contact effect.
And since the performance of the high conductivity of conducting contact 12 makes the contact resistance of the contact 1 lower, Jin Erneng
It enough reduces the fever of contact 1, reduce by 1 temperature rise of contact, to improve the through-current capability of connector.Meanwhile using split settings
Form can either meet the requirement of the elastic property of contact 1, also can satisfy the requirement of the low cost of contact 1, structure ratio
It is relatively simple, and actual processing is convenient, has certain versatility.
In the present embodiment, it is fixed together between above-mentioned conducting base 11 and conducting contact 12 by inlaying.
The embodiment 2 of contact of the invention, difference from example 1 is that, as shown in figure 4, the contact 1
Elastic top pressure side 111 is that multiple 114 spacing side by side of elastic slice are arranged to be formed, and all has corresponding receiving on each elastic slice 114
Slot 113, above-mentioned conducting contact 12 have it is multiple, with each holding tank 113 correspond.
In other embodiments, the material of above-mentioned conducting contact 12 can be using silver or the higher copper alloy of conductivity
Material；Above-mentioned conducting base 11 can use the Copper alloy material of other high conductivities, such as tin bronze, beryllium-bronze, have
Preferable mechanical performance, and conductivity is higher；It can be using such as riveting, welding between conducting base 11 and conducting contact 12
