[embodiment]
Below, will introduce the embodiment of the utility model electric connector terminal 20 in conjunction with Fig. 1 to Fig. 3 in detail.The utility model electric connector terminal 20 is in order to electrically connect external electronic building brick (as chip module, not shown) (not shown to circuit board, also can be other electronic building brick), it comprises first conducting terminal 10, second conducting terminal 11 and the spring 12 that connects first, second conducting terminal, and described first conducting terminal 10 and second conducting terminal 11 are sheet metal.
See also Fig. 1 to shown in Figure 3, first junction 102 that can electrically connect with external electronic building brick that first conducting terminal 10 comprises first pressure section 101, extends to form from first pressure section, 101 1 ends, and from the contact arm 103 of first pressure section, 101 other ends towards 11 extensions of second conducting terminal, wherein contact arm 103 dual-sides are provided with holding slot 104, and holding slot 104 runs through contact arm 103 1 ends.Be provided with fixture block 105 running through the ora terminalis place, this fixture block 105 outwards slowly protrudes out from holding slot 104, and it is a little less than elastic arm 113 sides.Holding slot 104 cross sections are semi-circular structure, form concave surface (not label) thus.Certainly, be not precluded within the situation that contact arm 103 4 sides all are provided with holding slot 104 or fixture block 105 in the specific implementation, this first pressure section 101 is the tabular structure of rectangle.
Second conducting terminal 11 is provided with second pressure section 111, wherein an end of this second pressure section 111 extends to form second junction 112 that can electrically connect with external electronic building brick, the other end extends to form a pair of elastic arm 113 that can flexibly support above-mentioned contact arm 103, this is to extend to form from second pressure section, 111 symmetries to elastic arm 113, and be wavy curved design, be formed with a plurality of contact points (not label) by this wavy curved design elastic arm 113 inboards, and another elastic arm 113 inboard same formation and the other one to one a plurality of contact points of described contact point of its correspondence, form a fixing folder 114 by contact point corresponding in twos on this two elastic arm 113, and the corresponding contact point minimum spacing outline of fixing folder 114 is less than the lateral separation of 104 of two holding slots.Thus, when contact arm 103 is inserted between the fixing folder 114, two elastic arms, 113 outside strains, thus fixing folder 114 can closely contact with holding slot 104 inwall multiple spots under the elastic restoring force effect.In the specific implementation, described elastic arm 113 corresponding holding slots 104 are provided with, and are not limited to only establish a pair of.
Please emphasis with reference to figure 1, during combination, spring 12 is enclosed within on the elastic arm 113 of second conducting terminal 11, and it is squeezed to second pressure section, 111 1 ends, then, elastic arm 113 is docked with the contact arm 103 of first conducting terminal 10, the fixing of described elastic arm 113 folder 114 is accommodated in the holding slot 104 by fixture block 105, and with its inwall Elastic Contact, last, unclamp compressed spring 12 and finish installation.When spring is in relaxed state, press from both sides 114 outermost end by fixture block 105 butt fixings, to reach purpose with first conducting terminal 10 and second conducting terminal, 11 fixings, can make 20 one-tenth of electric connector terminals as a whole like this, conveniently move, install and change this product.The width of first, second pressure section 101,111 is greater than the race diameter of spring 12, thereby spring 12 can not gone out in landing.When the utility model electric connector terminal 20 was placed in the insulating body of electric connector (not shown), it can only move up and down under the restriction of insulating body terminal channel.When electric connector electrically connects chip module to circuit board, first conducting terminal 10 is stressed and move towards second conducting terminal 11, the 113 corresponding skews laterally of two elastic arms, after first conducting terminal 10 moved a certain distance, the holding slot 104 of contact arm 103 was inserted between the fixing folder 114 of second conducting terminal 11 and closely contacts with fixing folder 114 under the elastic restoring force effect.First, second pressure section 101,111 makes spring 12 distortion with the two ends that are pressed on spring 12 respectively, first junction 102 under the elastic restoring force effect of spring 12 with chip module on the tight crimping of conducting strip.When chip module is not installed, first conducting terminal 10 does not stress, and under spring 12 effect, the resilience that will make progress of first conducting terminal 10 reaches original position, like this, has just formed the electric connection of compressible contact.
Be compared to existing electric connector terminal, the utility model electric connector terminal 20 is a linear formula on the whole, and the function that the terminal channel on the corresponding electric connector insulating body only need have restriction terminal double swerve gets final product, and therefore assembles more convenient.First, second terminal adopts the movement locus of holding slot 104 restriction elastic arms 113, and fixing folder 114 possesses the multiple spot way of contact, can guarantee that two conducting terminals dislocation can not take place and cause the loose contact phenomenon in the motion process, good electric property is provided, and fixture block 105 and the fixing of elastic arm 113 press from both sides 114 outermost end and cooperate and can make electric connector terminal 20 become integral body, thereby reach the convenient operation of moving, installing and changing product.
