Description

High density electrical connector

The utility model is relevant a kind of high density electrical connector, refers to a kind of interface top that gate is covered in connector that has especially, and the high density electrical connector of the dustproof effect of this connection device can be provided.

At present, for satisfying the demand of telecommunication high-speed transfer, the number of terminals of high density electrical connector is more and more many, and the more therefore number of terminals can't increase the volume of electric connector, but under existing volume, does configuration closely.Thereby, the configuration that terminal is not only close but also thin, required precision in the manufacturing improves relatively, also quite strict to the requirement of environment for use simultaneously, that is to say the docking groove that as far as possible to avoid dust or other impurity to fall into electric connector, particularly under dusty operational environment, to avoid influencing the telecommunication transmission of these conducting terminals.Existing high density electrical connector does not possess any dustproof construction, its docking groove exposes fully, not only make dust enter its inside easily, and some foreign matter also easy damaged be placed in conducting terminal in the docking groove, cause loose contact, telecommunication transmission performance to reduce.

The purpose of this utility model is to provide a kind of high density electrical connector with gate structure; this gate is arranged at the interface top of connector; gate is not covered in above the connector when connector uses; can prevent that dust or other impurity from falling into the connector docking groove, provides the effect of protection.

For achieving the above object, the utility model high density electrical connector is by the following technical solutions: it comprises one by insulation shell, the connector body that plurality of conductive terminals and metal shell are formed, wherein insulation shell has interface and composition surface, and both sides have the opposing parallel setting and extend the sidewall of interface, in order to support a gate, this sidewall is provided with an axis hole and an arc groove, corresponding rotating shaft and guide rod on the ccontaining gate of difference, gate is the centre of gyration with the rotating shaft, and its guide rod opens and closes control along sliding in the arc groove and driving the rotation that gate is made 90 degree scopes around the shaft to form gate.In addition, also be arranged with spring mechanism in the rotating shaft of gate, in order to the restoring force of closing gate to be provided, and to make under the gate normality and be in closed condition.

Borrow above-mentioned technical scheme, compare prior art, the utlity model has following advantage: the gate of this high density electrical connector can prevent that dust or other impurity from falling into the electric connector docking groove, to realize connector body good dust-proof effect, assurance inner conductive terminal telecommunication transmission can not received the influence of exogenous impurity, and can prolong the useful life of connector body.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.

Fig. 3 is the upward view of gate in the utility model.

Partial perspective view when Fig. 4 is the utility model high density electrical connector closing gate.

Fig. 5 is the stereogram of the utility model high density electrical connector gate when opening.

Fig. 6 is the left view of the utility model high density electrical connector gate when opening.

See also the three-dimensional exploded view that Figure 1 shows that the utility model high density electrical connector 1.As shown in the figure, this high density electrical connector 1 partly is made up of several terminals 11, insulation shell 12, metal shell 14 and gate 15 etc.Wherein insulation shell 12 and metal shell 14 are riveted together by the riveted holes 122 and 140 of two rivets 10 by separately.The middle part of insulation shell 12 be provided with terminal and core seat 120 and and insulation shell 12 between form a docking groove 121, terminal 11 is installed on the terminal and core seat 120.Vertically be provided with two parallel side walls 13 in the two ends of insulation shell 12, sidewall 13 is square tabular, the one edge is concordant with the bottom surface of insulation shell 12, width is wideer slightly than the width of insulation shell 12, on it away from insulation shell 12 and keep to the side the place one jiao, being provided with axis hole 130 and one is the center of circle and the arc groove 131 that is the quadrant arc shape with axis hole 130, and the posterior edges of this sidewall 13 also is provided with a non-return face 132 near the axis hole position.

See also Fig. 3 again.Position, two edges at gate 15 close longitudinallies is respectively equipped with rotating shaft 150 and guide rod 151, rotating shaft 150 is stretched out by a depressed part 153 places, be nested with a spring 16 on it and reinstall (as shown in Figure 2) among the axis hole 130 on the sidewall 13, gate 15 is that pivot rotates with this rotating shaft 150, and wherein this spring 16 has two forward foot in a step 160 and rear feet 161 that slightly are vertical relation mutually.Guide rod 151 is loaded in the arc groove 131 of sidewall 13 and can slides therein, thus the switch motion of guiding gate 15.In the lower surface of gate 15, extend a groove 152 by depressed part 153 places to gate 15 middle positions, its degree of depth equals spring 16 diameter of (as shown in Figure 1), and its length equals the length of the forward foot in a step 160 of spring 16.

As shown in Figure 4, gate 15 is supported between the two side 13 owing to the mating reaction of its rotating shaft 150 and guide rod 151 and axis hole 130 and arc groove 131 when gate 15 is closed.The rear foot 161 of spring 16 is by on the non-return face 132 of being located at sidewall 13, the forward foot in a step 160 then is placed in the groove 152 of gate 15 lower surfaces, because having, the forward foot in a step 160 and the rear foot 161 of this spring 16 slightly be the vertical stratification relation mutually, so, because the elastic force effect makes and also can slightly be vertical positional relationship between gate 15 and the non-return face 132, this moment, gate 15 was in closed condition, and level is covered in the top (as shown in Figure 2) of docking groove 121.

See also again Fig. 5 and Fig. 6 when electric connector 1 need be when other electronic components cooperate, its gate 15 is subjected to downward the pushing of electronic component (not shown), and the elastic force that surpasses spring 16 when this pressing force, the guide rod 151 of gate 15 just can slide along arc groove 131, gate 15 overcomes spring 16 elastic force and 150 is rotated down around the shaft simultaneously, vertical up to gate 15 with docking groove 121 planes, guide rod 151 supports the end of travel that terminates in arc groove 131, this moment, gate 15 was opened fully, and electronic component can dock with this high density electrical connector 1 easily.

Therefore, can be by what be installed in high density electrical connector 1 top to the gate mechanism of one-sided rotation, need be when other electronic components be connected at high density electrical connector 1, its gate 15 is opened because of being subjected to pushing, neither influence the work of high density electrical connector 1, and, when this high density electrical connector 1 is not connected with other electronic components, its gate 15 can be closed automatically because of spring 16 effects, like this, introduced contaminants just is difficult for falling into its docking groove 121, causes the consequence of terminal 11 loose contacts, thereby has improved the total quality of high density electrical connector 1.
