Abstract
The utility model discloses a card edge connector with a pre-compressing structure. A boss is formed on the front side walls of slots of upper conductive terminals in a projecting way. A boss rear inclined plane is formed on the rear end of the boss. Elastic arms of the upper conductive terminals are inclined downwards. Contact parts of the upper conductive terminals are formed in a way to retreat from the tail ends of the elastic arms of the upper conductive terminals and then extend. Projecting parts projecting towards the two sides are arranged on the tail end of each upper conductive terminal elastic arm. When the upper conductive terminals are inserted into an insulating body in group, the boss rear inclined plane of the insulating body guides the projecting parts of the upper conductive terminals to compress the elastic arms of the upper conductive terminals in an upward way. The upper conductive terminals are thus made to enable certain pre-compression after being inserted into the insulating body in group. The upper conductive terminals are thus aligned on the horizontal direction. The aim of overcoming problems that the upper conductive terminals are difficult to align and easy to damage during an insertion process is thus achieved on a using condition characterized by low installation height. The using performance of the card edge connector is thus improved.
Description
Technical field
The utility model relates to a kind of bayonet connector structure, especially a kind of bayonet connector structure that still has prepressing structure under than the low-mounting height operating position.
Background technology
As shown in Figure 1, be the bayonet connector of a prior art, this bayonet connector has insulating body 1, some conducting terminal 2 and some conducting terminals 3 down gone up.As shown in Figures 2 and 3, insulating body 1 has some conducting terminal slot 11 and some conducting terminal slots 12 down gone up, at the oriented projecting inward convex platform 110 in last conducting terminal slot 11 ends and convex platform back bevel 1101, at the same oriented projecting inward lower convex platform 120 in following conducting terminal slot 12 ends and lower convex platform front bevel 1201.As shown in Figure 4, the protuberance 21 of the oriented both sides of last conducting terminal 2 heads protrusion, when last conducting terminal 2 inserts aforementioned protuberance 21 upwards compression under the effect of convex platform rear ramped surface 1101 of going up conducting terminal 2 heads when going up conducting terminal slot 11, after last conducting terminal 2 inserts conducting terminal slot 11 fully, go up conducting terminal 2 head protuberances 21 and be close to aforementioned convex platform 110, thereby make that going up conducting terminal 2 keeps concordant in the horizontal direction.As shown in Figure 5, the same protuberance 31 that protrudes in the oriented both sides of following conducting terminal 3 heads, instantly conducting terminal 3 insert aforementioned conducting terminal slot 12 down at present conducting terminal 3 head protuberances 31 under the effect on the anterior inclined-plane 1201 of lower convex platform to lower compression, instantly conducting terminal 3 insert fully down conducting terminal slot 12 backs down conducting terminal 3 head protuberances 31 be close to aforementioned lower convex platform 120, thereby make that conducting terminal 3 keeps concordant in the horizontal direction down.Above-mentioned design makes terminal after insertion because decrement existence in advance can make terminal have bigger positive force, simultaneously since terminal after assembling in the horizontal direction concordant this connector that makes have serviceability preferably, in general, this establishes the needs that satisfy the legacy card edge connector fully.But along with connector constantly develops to littler thinner direction, the terminal structure of aforesaid way and compression process and form take up space excessive in short transverse, are difficult to adapt to connector and develop to littler thinner direction.

The utility model for the further technical scheme that solves its technical problem and adopt is:
Be preferably, be provided with the insulation filling body, described some conducting terminals of going up are incorporated into described upward insulation filling body, and described upward insulation filling body and described some conducting terminal formations that goes up go up the conducting terminal assembly, and described upward conducting terminal assembly is assembled and is immobilizated in described insulating body.
Say that further the described conducting terminal of going up partly is embedded in described going up in the insulation filling body.
Be preferably, be provided with down the insulation filling body, described some conducting terminals down are incorporated into described insulation filling body down, and described insulation filling body down and described some conducting terminals down constitute conducting terminal assembly down, and described conducting terminal assembly assembling down is immobilizated in described insulating body.
Say that further described conducting terminal down partly is embedded in the described insulation filling body down.
The beneficial effects of the utility model are: the last conducting terminal with bayonet connector of pre-pressing structure of the present utility model has last conducting terminal holding parts, last conducting terminal elastic arm and last conducting terminal contact site, last conducting terminal elastic arm extends forward from last conducting terminal holding parts and forms, and last conducting terminal elastic arm is downward-sloping shape, last conducting terminal contact site is turned back to extend from last conducting terminal elastic arm end and is formed, last conducting terminal elastic arm end protrudes to both sides and is formed with protuberance, when last conducting terminal group is gone into insulating body, the upwards compression of protuberance of conducting terminal is gone up in the boss back bevel guiding of insulating body, thereby make conducting terminal after group is gone into insulating body, certain precompressed be arranged, make the protuberance of going up conducting terminal be close to the boss of insulating body, thereby make that going up conducting terminal keeps concordant in the horizontal direction, go up the purpose of damaging when conducting terminal is prone to high low head and plug-in card thereby be implemented in to overcome under the low-mounting height operating position, promote the serviceability of bayonet connector.
