Abstract
A contact pin for a heavy-current electric connector comprises a base body of the contact pin, wherein, one section of the base body of the contact pin is a contact position which is in contact with a jack of the electric connector. The utility model is characterized in that two to eight evenly-distributed axial grooves are formed in the contact position of the base body of the contact pin; and a metal ring with an elastic opening can be arranged in the contact position of the base body of the contact pin. When being applied in the electric connector for transmitting a heavy current pin with hundreds of amperes, the contact pin improves the transmission stability, realizes the large contact pressure and the small resistance between the contact pin and the jack, as well as the reduction in the power loss of the electric connector.
Description
Technical field
The utility model belongs to the parts of electric connector, relates to a kind of large-current electric connector contact pin, is the improvement of prior art, 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 of contact pin and jack) three big elementary cells.After plug and socket plugged together, contact pin wherein inserted jack, and Flexible element therebetween 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, the Flexible element between contact pin and jack all is to be produced by jack, and it is simple in structure, is easy to produce; But under the big current conditions of hundreds of amperes of transmission, the contact pressure that needs must be very big, to reduce contact resistance, reduces power consumption; But prior art has significant limitation with jack as Flexible element, and its contact pressure is less, and the reliability of current delivery is lower.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, by at the contact site of contact pin matrix fluting etc., contact pin and jack pressed the large-current electric connector contact pin that power is big, contact resistance is little, power loss is little indirectly when a kind of the use was provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of large-current electric connector contact pin, comprise: the contact pin matrix, one section of this contact pin matrix is the contact site that contacts with jack in the electric connector, it is characterized in that: there is 2-8 equally distributed axial groove (4) contact site of described contact pin matrix (2).
In the technical solution of the utility model: can also be provided with elastic opening quoit (1) in the contact site of described contact pin matrix (2), to improve the stability of contact pressure.
In the technical solution of the utility model: with can also fluted (5) on the inner peripheral surface of the contact pin matrix (2) of the correspondence position of described elastic opening quoit (1), make that elastic opening quoit (1) is stable to be provided with.
In the technical solution of the utility model: the external diameter of the contact site of described contact pin matrix 2 is preferably the internal diameter that is equal to or greater than jack 3.
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 contact pin was subjected to the jack restrained deformation, produced contact pressure; The elastic opening quoit plays booster action to the distortion of contact pin contact site, makes the distortion of contact pin contact site keep stable state; Thereby make contact pin and jack press indirectly power obviously, contact resistance effectively reduces;
(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.

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 contact pin, comprise: contact pin matrix 2, one section of this contact pin matrix 2 is the contact site that contacts with jack in the electric connector, there are 4 equally distributed axial grooves 4 contact site of this contact pin matrix 2 (that is: in contact pin matrix 2 contacts site, process a cross recess, groove has certain width, allows bit space when making contact pin insert jack; Cross recess is processed with certain length, forms cantilever beam structure when making contact pin insert jack, and the contact pin contact site is subjected to the jack restrained deformation, thereby produces contact pressure); The contact site of contact pin matrix 2 is built-in with elastic opening (promptly enclosing upper shed) quoit 1, and (distortion to contact pin matrix 2 plays booster action, can make the distortion of contact pin matrix 2 keep stable state), and be provided with groove 5 with the inner peripheral surface of the contact pin matrix 2 of the correspondence position of elastic opening quoit 1.
During use, contact pin axially inserts along jack 3, (external diameter of the contact site of contact pin matrix 2 is preferably the internal diameter that is equal to or greater than jack 3), inserting back contact pin matrix 2 is subjected to jack 3 constraints and produces distortion, form the cantilever beam stress, simultaneously elastic opening quoit 1 is subjected to the constraint of contact pin matrix 2 distortion and produces distortion, and the distortion of contact pin matrix 2 is played booster action.
Under the prerequisite that guarantees operability, by regulating the size of 3 of contact pin matrix 2 and jacks, can change the deflection of contact pin matrix 2, thereby 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 contact 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 described good result.
Claims (3)
