Abstract

An electric connector contains an insulated body, a first conductive terminal, a second conductive terminal and a spring. Terminal accommodation holes are installed on the insulated body. The first conductive terminal and the second conductive terminal are installed in the accommodation holes, and the two terminals can connect with each other. The first conductive terminal is concave-up, and at least one chute is installed on the first conductive terminal. A flexible arm is installed on the second conductive terminal which can slide along the chute. A chute is installed on the first conductive terminal. The depth of the chute increases downward gradually along the direction of the contact jaw, reducing the resistance when the first conductive terminal is springing back. The first conductive terminal and the second conductive terminal are both in flake shape, which can keep the electric connector having a good capability, prolong the service life, and reduce the production cost.

Description

A kind of electric connector

[technical field]

The utility model relates to a kind of electric connector, especially a kind of electric connector that is provided with spring.

[background technology]

The electric connector that is provided with spring of the prior art, as described in No. 200410102051.1 patent of China, the electric connector that is provided with spring in this patent comprises: insulation crust has and is installed in a bottom surface on the board member; Conducting terminal can slide with the first direction that is parallel to this bottom surface thereby be set in this shell; Conductive terminal is set in this shell and has at least one flexure strip, and this flexure strip is contacted with the outer peripheral face of this conducting terminal all the time from the second direction perpendicular to this first direction; And elastic component, be set between this conducting terminal and this conductive terminal, simultaneously can indentation on this first direction so that give prominence to from shell on the top of this conducting terminal.Because this electric connector conducting terminal is by the shell fragment clamping, when conducting terminal is depressed, spring generation elastic deformation and shrinking, after the conducting terminal upward pressure removes, conducting terminal resilience under the spring force effect.Reducing in springback process along with spring deformation, its resilience force to conducting terminal also reduces gradually, but, because conducting terminal is subjected to shell fragment elastic force constant all the time, the resistance of shell fragment during to the conducting terminal resilience is also constant all the time, cause the conducting terminal resilience to be obstructed, and shell fragment remains bigger chucking power clamping conductive pin, long-term keep bigger elastic deformation to cause the shell fragment permanent deformation easily and follow the string, influence the electric connector overall performance, reduce electric connector useful life.Simultaneously, conductive pin is cylindric, and its difficulty of processing is bigger, and cost is higher.

Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[utility model content]

The purpose of this utility model be to provide a kind of conducting terminal can operate as normal under less resilience force effect and cost than the electric connector that is provided with spring at the end.

For achieving the above object, a kind of electric connector, comprise insulating body and first, second conducting terminal, spring, insulating body is provided with the terminal accommodation hole, wherein be provided with can interconnective first conducting terminal and second conducting terminal for each accommodation hole, it is characterized in that: be concaved with at least one skewed slot on first conducting terminal, second conducting terminal is provided with the elastic arm that can slide along skewed slot.

Wherein, described first, second conducting terminal is sheet.

Compared with prior art, the conducting terminal of the utility model electric connector is provided with skewed slot, and skewed slot matches with Elastic Contact elastic contact part thereon.When the conducting terminal resilience, because the skewed slot degree of depth increases gradually, reduce gradually with the elastic deformation of the elastic contact part of skewed slot resilient engagement, suffered resistance reduces gradually when making the conducting terminal resilience, guarantee its resilience smoothly, avoiding being obstructed because of resilience influences electric electric connector overall performance, and owing to be held on the elastic arm of skewed slot both sides and remove the back elastic deformation at the conducting terminal upward pressure and reduce, avoid elastic arm for a long time than permanent deformation under the large elastic deformation, increase electric connector useful life.Simultaneously, because first, second conducting terminal is sheet, its difficulty of processing is less, and cost is the end of than.

Below in conjunction with accompanying drawing the utility model electric connector is described further.

See also Fig. 1 to Figure 11, the utility model electric connector 1 can connect two butt joint electronic building bricks (not shown), comprises insulating body 10, first conducting terminal 11, second conducting terminal 12 and is arranged at spring 13 between first, second conducting terminal.

Insulating body 10 is provided with the two terminal accommodation holes 101 that run through its upper and lower surface, and this terminal accommodation hole 101 is a cross, comprise the first conducting terminal accommodation hole 1011 and with the orthogonal second conducting terminal accommodation hole 1012 of the first conducting terminal accommodation hole.Between the two-terminal accommodation hole of insulating body 10 upper surfaces, be provided with a flat surface 105, in the process that electric connector is installed to the butt joint electronic building brick, this flat surface 105 can supply vacuum slot (not shown) absorption, is convenient to automation and installs, to improve installation rate.Between the two-terminal accommodation hole of insulating body 10 lower surfaces, be provided with and draw material hole 106.

First conducting terminal 11 comprises base portion 110, and extend upward by base portion 110 upper ends and to be provided with contact jaw 112, extend downwards respectively by base portion 110 lower ends two side positions and to be provided with two arms 114, base portion 110 is provided with the abutting part 113 that connects with spring 13 near arm 114 ends, cave inward on the relative two sides of first conducting terminal, 11 base portions 110 and form skewed slot 111, it extends to form by being directed downwards near contact jaw 112, and skewed slot 111 increases gradually along being directed downwards the degree of depth by contact jaw 112.

Second conducting terminal 12 comprises main part 120, extend upward the junction 123 that is provided with two elastic arms 121 and extends respectively downwards by main part 120 both sides, two elastic arms 121 are pressed on respectively in the skewed slot 111 of first conducting terminal, 11 base portions, 110 both sides, elastic arm 121 can slide along skewed slot 111, and elastic arm 121 ends are to the projecting inward contact site 1211,1212 that is provided with skewed slot 111 Elastic Contact.Be provided with the registration arm 122 that extends upward by main part 120 in the inserted spring 13 that forms 121 of two elastic arms.Main part 120 both sides are provided with interference part 124, and when second conducting terminal 12 was arranged in the terminal accommodation hole 102, this interference part 124 can hold the hole wall interference engagement with second conducting terminal, to increase the confining force of second conducting terminal 12 in insulating body 10.

When first, second conducting
