The elastic body is contained in the sleeve of the metal shell, one end of the elastic body is contacted on the bottom surface of the sliding part in a resisting way, and the other end thereof is abutting on the base. As the welding part is arranged on the lower bottom surface of the base of the sleeve in a convex way, the procedure that the probe is welded on a circuit board is simple, the production cost is low and impedance with the circuit board can be reduced.

Description

Probe

Technical field

The utility model relates to a kind of connector technique, relates in particular to a kind of probe as connector.

Background technology

See also Fig. 5, a kind of existing probe 100 ' has a metal shell 1 ', a metal probe 2 ' and an elastomer 3 '.This metal shell 1 ' has a sleeve 11 ', and the bottom of sleeve 11 ' is connected with the base 14 ' of a sealing, and the top of sleeve 11 ' bends inwards and extended to form a stopper section 12 ', and stopper section 12 ' has an opening 13 '; Metal probe 2 ' has a sliding part 22 ' and by this sliding part 22 ' convex contact site 21 ' that stretches out, and sliding part 22 ' is installed in the sleeve 11 ' of metal shell 1 ', and contact site 21 ' stretches out outside the metal shell 1 ' from opening 13 '; Elastomer 3 ' is contained in the sleeve 11 ' of metal shell 1 ', and an end of elastomer 3 ' contacts at the bottom surface of sliding part 22 ', and the other end is resisted against on the base 14 '.

Yet above-mentioned probe 100 ' is when being welded to circuit board, because metal shell 1 ' locates not to be provided with weld part, so need install switching piece in addition additional, make that the production cost is higher, operation is complicated, and installs switching piece additional and makes probe increase impedance, influences the quality of probe.

The utility model content

Main purpose of the present utility model is to provide a kind of probe at the defective that above-mentioned prior art exists, and the operation that this probe is welded to circuit board is simple, production cost is low, and can reduce and circuit board between impedance.

For achieving the above object, the utility model probe has a metal shell, a metal probe and an elastomer.Metal shell has a sleeve, and sleeve one end bends inwards and extends to form a stopper section, and the stopper section has an opening, and the sleeve other end is connected with a base, and the bottom surface of base convexes with a weld part.Metal probe has a sliding part and by the convex contact site that stretches out of sliding part, and sliding part is installed in the sleeve, and contact site is outside opening stretches out metal shell.Elastomer is contained in the sleeve of metal shell, and an elastomeric end contacts at the sliding part bottom surface, and the other end is resisted against on the base.

As mentioned above, the utility model probe is owing to be convexly equipped with a weld part at the place, bottom surface of the base of metal shell, this weld part can be directly welded on the circuit board, so needn't install switching piece in addition additional, this probe is welded to that the operation of circuit board is simple, production cost is low thus, and can reduce and circuit board between impedance.

Embodiment

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

See also Fig. 2, the utility model probe 100 has a metal shell 1, a metal probe 2 and an elastomer 3.

See also Fig. 2 and Fig. 3, metal shell 1 has a cylindrical circular sleeve 11, the stopper section 12 that one end of sleeve 11 bends inwards and extends to form an annular, stopper section 12 has an opening 13, sleeve 11 other ends are connected with a base 15, cave inward with base 15 junctions on the outer surface of sleeve 11 and form an annular buckle slot 14, base 15 bottom surfaces have outwards protruded out a weld part 16.

Metal probe 2 has a cylindrical sliding part 22 and by these sliding part 22 convex cylindrical contact sites 21 that stretch out, sliding part 22 is installed in the sleeve 11 of metal shell 1, and the diameter of sliding part 22 is greater than the diameter of opening 13, so that sliding part 22 is fastened in the sleeve 11, the bottom surface of sliding part 22 is an inclined-plane, contact site 21 is outside opening 13 stretches out metal shell 1, thereby contact site 21 can electrically connect with exterior electrical components.

Elastomer 3 is contained in the sleeve 11 of metal shell 1, and an end of this elastomer 3 contacts at sliding part 22 bottom surfaces, and the other end is resisted against on the base 15.

See also Fig. 4, when this probe 100 of assembling, earlier some probes 100 are installed on the insulator 4, and form a probe-type connector; Again insulator 4 is welded on the circuit board 5; Weld part 16 with probe is welded on the circuit board by the opening (not shown) on the insulator 4 at last, to provide the loop required connection.

In sum, the utility model probe 100 is convexly equipped with a weld part 16 in the place, bottom surface of the base 15 of metal shell 1, and weld part 16 can be directly welded on the circuit board 5, and the utility model probe 100 manufacturing processes are simple thus, production cost is low and impedance is low.
