Abstract

The utility model relates to a socket of a power connector used in electric test, provided with a crown spring socket, wherein the socket consists of a socket body (1), a crown spring (2) and a positioning column (4). The central part of the socket body (1) is provided with a blind hole shaped socket (3) in the axial direction, wherein the socket (3) is a stepped hole with the bigger middle and the smaller two ends; the crown spring (2) is embedded in the bigger hole of the socket (3) to form the crown spring socket; the positioning column (4) extends in the radial direction into the wall of the socket (3) below the crown spring socket. The utility model has the characteristics of high reliability, and is especially suitable to be connected with a high-current power source.

Description

Power test is preced with the power connector socket of spring socket with band

Technical field

The utility model relates to a kind of power connector, especially relates to the power connector socket that a kind of power test is used.Being mainly used in the power supply of power department in the power test process connects.

Background technology

The power connector that power test is used includes socket and plug.The jack of socket generally is to adopt the sheet spring structure, and one of its shortcoming is that jack follows the string easily and lost efficacy, and reliability is relatively poor; Two of shortcoming is that the contact-making surface of sheet spring and plug is little, can only be applicable to that the power supply of less electric current (generally about 5A, maximum must not greater than 20A) connects.And some measuring current reaches 100A at present, and above-mentioned power connector just can not be suitable for.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, a kind of good reliability is provided, is specially adapted to the power test power connector socket of being with the hat spring socket that high-current supply connects.

The purpose of this utility model is achieved in that the power connector socket of a kind of power test with band hat spring socket, it is characterized in that described socket comprises jack body, hat spring and reference column, the jack body central shaft is to offering a blind hole shape jack, the step that this jack is broad in the middle, two is little is poroid, the hat spring is embedded in the macropore of this jack, form the hat spring socket, cross-under reference column radially on the jack hole wall below the hat spring socket.

During use, in the hat spring socket with plug insertion socket, the tight envelope of plurality of elastic bonding jumper in the middle of the hat spring constitutes multi-thread contact system in parallel on the surface of plug.Promptly a hat spring socket is equivalent to use the sheet spring is in parallel simultaneously several, has improved the contact area between plug and the socket greatly, has improved both contact reliabilities.Therefore be specially adapted to the connection of high-current supply.

The utility model power test is preced with the power connector socket of spring socket with band, described hat spring be with elastic metal strip on request punching press be divided into the strip that some two ends link to each other, be rolled into circle then, the circumferencial direction of circle does not seal, make this circle leave an elongated opening at length direction, and its middle part is with a tight waist, form the structure that is similar to the imperial crown shape of being small at both ends and big in the middle.It is to embed in the jack of socket for the ease of the hat spring that hat spring circumferencial direction does not seal, and makes the macropore of the jack of hat spring two ends outer rim and socket realize interference fit, can further improve contact reliability.

In sum, the plug contact area of the utility model and power connector is big, and contact reliability is good, and the power test that is specially adapted to the high-current supply connection connects with power supply.

Among the figure: jack body 1, hat spring 2, jack 3, reference column 4.

Embodiment

Referring to Fig. 1～3, the utility model power test is made up of jack body 1, hat spring 2 and reference column 4 with the power connector socket of band hat spring socket.Jack body 1 central shaft is to offering a blind hole shape jack 3, and this step that jack 3 is broad in the middle, two is little is poroid, and hat spring 2 is embedded in the macropore of this jack 3, forms the hat spring socket, cross-under reference column 4 radially on jack 3 hole walls below the hat spring socket.

Referring to Fig. 4, described hat spring 2 be with elastic metal strip on request punching press be divided into the strip that some two ends link to each other, be rolled into circle then, the circumferencial direction of circle does not seal, make this circle leave an elongated opening at length direction, and its middle part is with a tight waist, form the structure that is similar to the imperial crown shape of being small at both ends and big in the middle.
