Yet above-mentioned probe-type connector 1 ' is when being subjected to vibrating, and metal probe 20 ' instantaneous disconnection occurs easily with electrically conducting of metal sleeve 10 '; When metal probe 20 ' and metal sleeve 10 ' electrically conducted and disconnect, elastomer 30 ' can produce high temperature because of its high-impedance behavior, thereby influenced the probe-type connector 1 ' performance that electrically conducts.

The utility model content

Main purpose of the present utility model is to provide a kind of probe-type connector at the defective that above-mentioned prior art exists, and the metal probe of this probe-type connector is connected stable with the metal sleeve contact, thereby the electric connection of probe-type connector is reliable.

For achieving the above object, the utility model provides the probe-type connector to comprise a metal sleeve, a metal probe, one first elastomer and one second elastomer.Metal sleeve has a housing, and housing bottom is connected with a base, and the top of housing bends inwards and extended to form a stopper section, and the stopper section has an opening.Metal probe has sliding part and by the convex contact site that stretches out of this sliding part, sliding part is installed in the housing of metal sleeve, and contact site is outside opening stretches out metal sleeve.First elastomer is contained in the housing of metal sleeve, and the one end contacts on the bottom surface of sliding part, and its other end is resisted against base.Second elastomer is fixed on the housing, and this second elastomer has a side opening by housing and stretches in the housing and can be resisted against top on the side of sliding part.

Metal probe of the present utility model is when being pressed into metal sleeve with metal probe, because the second elastomeric top is replaced the sliding part that acts on metal probe from the side, the metal probe sliding part can more stably be contacted with the inwall of metal sleeve, thereby the electric connection of probe-type connector is reliable.

Embodiment

For describing technology contents of the present utility model, structural feature and purpose of being reached and effect in detail, below in conjunction with embodiment and cooperate the graphic detailed explanation of giving.

See also Fig. 1, Fig. 2, the utility model probe-type connector 1 has a metal sleeve 10, a metal probe 20, one first elastomer 30 and one second elastomer 40.

Metal sleeve 10 has a cylindrical circular housing 11, housing 11 bottoms are connected with the base 12 of a sealing, one end of housing 11 bends inwards and has extended to form an annular stopper section 13, stopper section 13 has an opening 14, the marginal surface of base 12 offers a firm groove 121, and upwards offers a stopper slot 122 that communicates with firm groove 121 along the surface of base 12.

Metal probe 20 has a cylindrical sliding part 22 and by the sliding part 22 convex cylindrical contact sites 21 that stretch out.Sliding part 22 is installed in the housing 11 of metal sleeve 10, and the bottom surface of sliding part 22 is an inclined plane, and the diameter of sliding part 22 greater than the diameter of opening 14 so that sliding part 22 be fastened in the housing 11; The diameter of contact site 21 is less than the diameter of opening 15, and the opening 14 that this contact site 21 passes metal sleeve 10 stretches out outside the metal sleeve 10, thereby contact site 21 can electrically connect with external electronic components.

First elastomer 30 is contained in the housing 11 of metal sleeve 10, and the one end contacts on the bottom surface of sliding part 22, and the other end is in being resisted against on the base 12.

Second elastomer 40 is fixed on the housing 11, and this second elastomer 40 has in the form of a ring a firm ring 42 roughly, firmly encircles the 42 top covers from metal sleeve 10 and is installed in the firm groove 121 of base 12 down.An elastic arm portion 43 is extended in bending on the firm ring 42, elastic arm portion 43 is contained in the stopper slot 122, the 43 terminal bendings of elastic arm portion have extended to form a top 41, and top 41 stretches in the housing 11 by the side opening 111 of housing 11, and top 41 can be resisted against on the side of sliding part 22.

Please continue and consult Fig. 1, Fig. 2, when this probe-type connector 1 of assembling, can earlier metal probe 20 be packed into from housing 11 tops, thereby inside again pressing housing 11 upper ends form the stopper section 13 of described annular.

Please refer to Fig. 3, when this probe-type connector 1 was in user mode, metal probe 20 was subjected to external force and moves down, metal probe 20 downward compresses elastomeric 30, to lower slider, the sliding part 22 that acts on metal probe 20 is replaced in the top 41 of second elastomer 40 to sliding part 22 along housing 11 inwalls.

In sum, the metal probe 20 of the utility model probe-type connector 1 is when being pressed into metal sleeve 10 with metal probe 20, because the top 41 of second elastomer 40 is replaced the sliding part 22 that acts on metal probe 20 from the side, make the sliding part 22 of metal probe 20 can more stably be contacted with the inwall of metal sleeve 10, thereby the electric connection of probe-type connector 1 is reliable.
