Abstract

The invention discloses a high-carrying-current electric connector which comprises a contact pin and a jack and is characterized in that: one end of the jack is provided with a reed splicing hole, the other end of the jack is provided with an electric contact element of a groove splicing hole, an annular groove is arranged on the reed splicing hole, a port of the reed splicing hole is provided with a punching bag structure, and a spring coil is clamped on the annular groove; a needle-shaped plug is arranged at one end of the contact pin, and an electric contact element of the groove splicing hole is arranged at the other end of the contact pin; the contact pin and the jack are fixedly arranged on an upper insulation body and a lower insulation body; and an upper end cover and a lower end cover are buckled and encapsulated to form the electric connector. Compared with the prior art, the high-carrying-current electric connector has the advantages of high current, increase in value at low temperature and good clamping force of the jack, greatly meets the specification requirement that the temperature rise value is not more than 30 DEG C when the connector works under the high carrying current of 50A and is especially suitable for system connection of high carrying current in the field of electronic communication.

Description

High current-carrying electric connector

Technical field

The present invention relates to technical field of electronic components, especially a kind of high current-carrying electric connector.

Background technology

In current telecommunications field, voice transfer for example, transfer of data, occasions such as image transmission, desired signal velocity is more and more faster, and frequency is more and more higher, power also more and more, simultaneously, systematization and integrated degree are more and more higher, corresponding, the use of electric connector also more and more widely, along with the development of electric connector industry, the required operating current of increasing electrical system is all bigger, generally all will surpass 30A.But, the specified maximum current of the electric connector of prior art is 30A, have only operating current≤30A it to guarantee operate as normal, because its permission of the contact of electric connector operate as normal under the condition of 30 ℃ temperature rise value, but contact≤30 ℃ temperature rise value, its rated current is 30A to the maximum, when 50A is arrived in connector work, the temperature rise value of its test up to 40 ℃ about, be far longer than 30 ℃, this just exceeds the requirement of industry to 30 ℃ of temperature rise values of connector, bring more heat to system, the operate as normal that is unfavorable for system has restricted the telecommunications industry greatly towards big capacity, the development of high-power system.

Summary of the invention

The objective of the invention is a kind of high current-carrying electric connector that designs at the deficiencies in the prior art, it adopts the reed jack of peripheral hardware elasticity spring coil, make reed plug together the back and keep certain chucking power contact pin, to satisfy under the electric current that connector is operated in 50A, the code requirement of temperature rise value≤30 ℃ is realized the reliable connection and the transmission of big electric current.

The object of the present invention is achieved like this: a kind of high current-carrying electric connector, comprise contact pin, jack, upper insulator and lower insulator, contact pin and jack are arranged on the upper and lower insulator, fasten by upper end cover and bottom end cover, be characterized in that jack one end is the reed spliced eye, the other end is the electrical contact of groove spliced eye, and the reed spliced eye is provided with annular groove, its port is provided with towards pack arrangement, and card is established spring coil on the annular groove; Contact pin one end is the needle-like plug, and the other end is the electrical contact of groove spliced eye; Upper and lower end covers and is provided with plug receptacle; Contact pin and jack are fixedly installed on the upper and lower insulator, are fastened by upper and lower end cap and are packaged into electric connector.

The material of described reed spliced eye is a tellurium copper.

The present invention compared with prior art has big electric current, low temperature rise value, the chucking power of jack is good, and is simple in structure, easy to make, having satisfied the high live that connector is operated in 50A greatly flows down, the code requirement of temperature rise value≤30 ℃ is realized the reliable connection and the transmission of big electric current, has improved production efficiency and security performance, and simple in structure, the system that especially is fit to high current-carrying in the telecommunications field connects.

Embodiment

Consult accompanying drawing 1～accompanying drawing 2, the present invention is by the contact pin 3 that is arranged on upper insulator 5 and the lower insulator 6, jack 4 and upper end cover 1, bottom end cover 2 is formed, on,

bottom end cover

1,2 for being provided with the shell of plug receptacle 12, contact pin 3 and jack 4 are fixedly installed on, lower insulator 5, on 6, fasten the electric connector that is packaged into rectangle by upper end cover 1 and bottom end cover 2, upper end cover 1 is fastening by screw after fastening with bottom end cover 2, the groove spliced eye 44 of contact pin 3 and jack 4 one ends is open outside the plug receptacle 12 of bottom end cover 2, and the plug 31 of the contact pin 3 and jack 4 other ends and reed spliced eye 43 are open in the plug receptacle 12 of upper end cover 1.

Consult accompanying drawing 3, jack 4 one ends are reed spliced eye 43, and the other end is the electrical contact of groove spliced eye 44, and reed spliced eye 43 is a tellurium copper material processing and fabricating, and reed spliced eye 43 is provided with annular groove 42, and its port is provided with towards pack arrangement 41.

Consult accompanying drawing 4, card is established spring coil 7 on the annular groove 42, and spring coil 7 is made by elastomeric material, can make 43 pairs of contacts that patch of reed spliced eye have good confining force after card is established spring coil 7 on the jack 4.

Consult accompanying drawing 5, contact pin 3 one ends are needle-like plug 31, and the other end is the electrical contact of groove jack 44.

More than just the present invention is further illustrated, is not in order to the restriction this patent, all for the present invention's equivalence enforcement, all should be contained within the claim scope of this patent.
