Abstract

The utility model relates to an electric connector, which comprises an insulation body and conductive terminals, wherein the insulation body is provided with a plurality of terminal containing holes which can contain the conductive terminals, elastic arms are arranged on the conductive terminals and the elastic arms are coated with soft elastic colloid. The elastic arms of the conductive terminals of the electric connector of the utility model are coated with soft elastic colloid, when the conductive terminals are pressed, the elastic colloid can enhance forward direction force of the conductive terminals by preventing the deformation of the conductive terminals. Simultaneously, when the conductive terminal is greatly pressed or is impacted, the elastic colloid can effectively protect the conductive terminals, and can avoid the non-restoration of the conductive terminals owing to the plastic deformation. Thereby, the conductive terminals can not effectively contact with foreign elements, which causes the electric connector not to keep normal electrical conduction.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, and especially a kind of and external element is the electric connector that adopts compression to contact.

[background technology]

Electric connector by conducting terminal contact portion and external element Elastic Contact to realize its linkage function, so the flexible quality of electric connector conducting terminal can have influence on the quality of whole electric connector performance.Shown in Figure 2 as Fig. 1, common electric connector conducting terminal 1 roughly is " C " font at present, and its two ends are respectively equipped with welding ends 2 and contact jaw 3.During assembling, this conducting terminal 1 is inserted in the rectangular conductive terminal accommodation hole 5 in the insulating body 4, and this conducting terminal welding ends 2 is fixed together with tin ball 6.After this electric connector assembling is finished, by heating furnace, both are welded mutually with circuit board 7.During use, external element 8 (as circuit board, chip etc.) is pressed on the electric connector conducting terminal 1 from top to bottom, and the conducting end 9 of external element is contacted with conducting terminal contact jaw 3, thereby reaches electrically conducting between external element 8 and the circuit board 7.Therefore, during use, this conducting terminal contact jaw 3 can be subjected to a downward pressure, makes conducting terminal produce strain.But this conducting terminal is because deformation space is excessive, the positive force of terminal is less, and through pressurized repeatedly, can't restore because of plastic deformation possibly after particularly being impacted, thereby can't effectively contact with external element 8, cause electric connector normally to work.

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

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector, can guarantee normally electrically conducting of electric connector.

For achieving the above object, the utility model electric connector comprises insulating body and conducting terminal, and insulating body is provided with some terminal accommodation holes of accommodating conducting terminal, and conducting terminal is provided with elastic arm, is coated with soft elastic gel on the elastic arm.

Compared with prior art; the utility model electric connector is coated with soft elastic gel on the elastic arm of conducting terminal; when the conducting terminal pressurized; elastic gel can improve the positive force of conducting terminal by stoping the conducting terminal deflection; simultaneously; when conducting terminal is stressed big or is subjected to impacting; elastic gel can effectively be protected conducting terminal; avoid conducting terminal can't restore because of plastic deformation; thereby can't effectively contact with external element, cause electric connector can't keep normally electrically conducting.

[embodiment]

With specific embodiment the utility model electric connector is described further with reference to the accompanying drawings.

Please refer to Fig. 3 to shown in Figure 8, the utility model electric connector is in order to be connected to external element 60 (can be chip module or circuit board) on the circuit board (not shown), comprise insulating body 10, conducting terminal 20, be positioned at insulating body 10 belows following iron-clad 30, be positioned at upper iron shell 40 and rocking bar 50 that iron-clad 30 two ends down are articulated with following iron-clad 30 respectively.

Insulating body 10 is provided with plurality of terminals accommodation hole 101, to accommodate conduction conducting terminal 20, terminal accommodation hole 101 is oblique arrangement in insulating body 10, maintain suitable space length between the middle part of accommodation hole 101 and the conducting terminal 20, to absorb conducting terminal 20 deflection when stressed.

Conducting terminal 20 is provided with two elastic arms 201 (certainly; also can be plural elastic arm; but should make conducting terminal have better elastic; the structure of conducting terminal is simpler again; article two, elastic arm is a most preferred embodiment of the present utility model); wherein two elastic arms 201 are crooked in the opposite direction diametrically; both roughly are " () " shape; whole stress balance when this makes the conducting terminal pressurized; on elastic arm 201, be coated with soft elastic gel 80; when conducting terminal 20 pressurizeds; elastic gel 80 can improve the positive force of conducting terminal 20 by prevention conducting terminal 20 deflections, simultaneously, and when conducting terminal 20 is stressed big or is subjected to impacting; elastic gel 80 can effectively be protected conducting terminal 20, and conducting terminal 20 takes shape in the elastic gel 80 for plug-in type.Extend respectively by the two ends of elastic arm 201 and to be provided with base portion 202 and the contact site 204 that is tabular, the width of elastic arm 201 is less than the width of base portion 202 with contact site 204, make the elasticity of elastic arm 201 better, base portion 202 can overlap scolder 70 (being the tin ball in the present embodiment), to be welded on the circuit board (not shown), the upper surface of contact site 204 outstanding insulating bodies 10 is to form the contact point that compresses contact with external element 60 mutually.

During assembling, insulating body 10 is installed in down in the iron-clad 30, again electric connector is welded together mutually with circuit board (not shown), afterwards external element 60 is connected in the zone that insulating body 10 is provided with conducting terminal 20, upper iron shell 40 is covered on external element 60 again, last closed rocking bar 50, at this moment external element 60 are promptly realized electrically conducting between external element 60 and the circuit board (not shown) by firm being fixed on the insulating body 10.

Because the utility model electric connector is coated with soft elastic gel on the elastic arm of conducting terminal; when the conducting terminal pressurized; elastic gel can improve the positive force of conducting terminal by stoping the conducting terminal deflection; simultaneously; when conducting terminal was stressed big or is subjected to impacting, elastic gel can effectively be protected conducting terminal, avoids conducting terminal can't restore because of plastic deformation; thereby can't effectively contact with external element, cause electric connector can't keep normally electrically conducting.

Certainly, the base portion of the conducting terminal of the utility model electric connector also can protrude from terminal accommodation hole lower surface, forms another contact site, can compress contact (not shown this execution mode) mutually with another external element.

Please refer to Fig. 9, shown in Figure 10, second embodiment for the utility model electric connector, be with the first embodiment difference: in the present embodiment, upwards only extend an elastic arm 201 ' by base portion 202 ', and this elastic arm 201 ' is extended upward by the centre position of base portion 202 ' and forms.It also can reach the described purpose of the foregoing description in implementation process.
