The utility model is applied to the electric connector transmitting hundreds of amperes of great current, and can effectively improve the transmitting stability and reduce the wasted power on the electric connector under the precondition that the operability of the electric connector can be ensured.
Description
Technical field
The utility model belongs to the parts of electric connector, relates to a kind of large-current electric connector jack, is that prior art is improved, and is specially adapted to transmit the electric connector employing of the above electric current of 300A.
Background technology
Electric connector is made up of plug and socket, comprises housing, insulator, contact (being made up of contact pin and jack) three big elementary cells.After plug and socket plugged together, wherein contact pin inserted jack, and wherein the Flexible element of jack makes between contact pin and jack and produces contact pressure, thereby electric current can be transmitted between contact pin and jack.In the prior art, jack simple in structure is easy to produce, but in the big electric current of transmission too big, the inconvenient operation of contact engaging and separating force, be difficult to bear big electric current, practicality is relatively poor.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, close up, further in the hole, install additional hat spring etc. by the jack fluting, provide a kind of jack satisfying under the soft situation of plug, can reduce contact resistance and power loss, satisfying the large-current electric connector jack that big electric current passes through.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of large-current electric connector jack, comprise: the jack matrix, one section of this jack matrix is the contact portion that contacts with contact pin in the electric connector, it is characterized in that: the contact portion of described jack matrix (1) has 2-10 equally distributed axial groove (2) for one section, and hat spring (3) is housed in the contact portion of described jack matrix (1).
In the technical solution of the utility model: on the inner peripheral surface of the jack matrix (1) corresponding fluted (4), make the stable setting of hat spring (3) with the position of described hat spring (3).
In the technical solution of the utility model: the contact portion of described jack matrix (1) is outer can also to be with elastic opening quoit (5), to improve the stability of contact pressure.
On the outer circumference surface of the jack matrix (1) corresponding fluted (6), make the stable setting of elastic opening quoit (5) with the position of described elastic opening quoit (5).
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) adopt the utility model, when contact pin inserted jack, the contact site of jack was subjected to the dilatating and deformable of contact pin, produced contact pressure; The elastic opening quoit plays booster action to the distortion of jack contact site, makes the distortion of jack contact site keep stable state; Thereby make contact pin and jack press indirectly power obviously, contact resistance effectively reduces; When contact pin was inserted into, the hat spring in the front end contact portion of contact pin and the jack produced Elastic Contact, has increased contact area, thereby has effectively reduced contact resistance;
(2) the utility model is applied to transmit in the electric connector of the big electric current of hundreds of amperes, under the prerequisite of the operability that guarantees electric connector, can effectively improve the stability of transmission, and the power of loss on the electric connector is reduced;
(3) simple in structure, produce easy to install, practical.
Description of drawings

Fig. 2 is the left TV structure schematic diagram of Fig. 1;
Fig. 3 is the sectional structure schematic diagram of Fig. 1;
Fig. 4 is the user mode structural representation of the utility model embodiment 1.
Among the figure: 1-jack matrix, 2-axial groove, 3-hat spring, 4-hat spring are installed groove, 5-elastic opening quoit, 6-groove, 7-contact pin.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of large-current electric connector jack, comprise: jack matrix 1, one section of this jack matrix 1 is the contact portion that contacts with contact pin 7 in the electric connector, the contact portion of jack matrix 1 has 8 equally distributed axial grooves 2 for one section, form cantilever beam structure when making contact pin 7 insert jack, the jack contact site is subjected to the crimp of contact pin, thereby produces pressure; Hat spring 3 is housed in the contact portion of jack matrix 1,, makes hat spring 3 stable settings with fluted 4 on the inner peripheral surface of the corresponding jack matrix 1 in position of hat spring 3; The contact portion of jack matrix 1 also is with elastic opening quoit 5 outward, can be out of shape booster action to the jack matrix, make the distortion of jack matrix 1 keep stable state, and the outer circumference surface of the jack matrix 1 corresponding with the position of described elastic opening quoit 5 is provided with groove 6, makes elastic opening quoit 5 stable settings.
During use, contact pin 7 axially inserts along jack matrix 1, inserts back jack matrix 1 and is subjected to the extruding of contact pin 7 to produce distortion, forms the cantilever force state, simultaneously elastic opening quoit 5 is subjected to 1 distortion of jack matrix and produces distortion, and the distortion of jack matrix 1 is played booster action; The front end of contact pin contact site inserts hat spring 3 simultaneously, make hat spring 3 produce distortion, thereby hat spring 3 tightly suppresses contact pin 7, increases the contact area of jack and contact pin 7, to reduce contact resistance.
Guaranteeing under the prerequisite of operability, by regulate the contact pin contact site with and jack between size, can change the deflection of jack, thus the change contact pressure.
Adopt this embodiment, when transmitting the big electric currents of hundreds of ampere, under the prerequisite of the operability that guarantees electric connector, contact to pressure can maximize, contact resistance minimizes, its power loss is also very little.
The utility model is not limited to the foregoing description, and the utility model content is described all can implement and have good effect.
