Abstract

The utility model discloses a probe type connector which is provided with a sleeve, a probe and an elastic body; the sleeve is provided with a housing; a closed base seat is connected to the bottom of the housing; the base seat and the housing surround an accommodation space; one end of the housing bends inwards and extends to form a stop part with an opening, and the other end thereof extends inwards to form a support part with a cavity; the probe is provided with a sliding part and a contact part; the sliding part is mounted in the sleeve; the contact part extends out of the sleeve from the opening; the elastic body is accommodated in the sleeve; and one end of the elastic body is propped against the probe, and the other end thereof is accommodated in the cavity of the support part. The probe type connector relies on the cavity of the support part to fix the elastic body, so as to prevent that the elastic body inclines and influences the assembly process when the probe is mounted from the top part of the housing, and to avoid that the service life is reduced after use because of long-term bending of the elastic body.

Description

The probe-type connector

Technical field

The utility model relates to a kind of connector, particularly relates to a kind of probe-type connector.

Background technology

See also Fig. 2, a kind of probe-type connector 1 ' includes a sleeve 10 ', a probe 20 ' and one elastomer 30 '.This sleeve 10 ' has a housing 11 ', the bottom of housing 11 ' is connected with the base 12 ' of a sealing, this base 12 ' and housing 11 ' surround an accommodation space 13 ', and an end of housing 11 ' bends inwards and extended to form a stopper section 14 ', and stopper section 14 ' has an opening 15 '.Probe 20 ' has a sliding part 21 ' and by this sliding part 21 ' convex contact site 22 ' that stretches out, sliding part 21 ' is installed in the housing 11 ' of sleeve 10 ', contact site 22 ' stretches out outside the sleeve 10 ' from opening 15 ', and the bottom surface of this sliding part 21 ' is concaved with a groove 211 '; Elastomer 30 ' is contained in the accommodation space 13 ' of sleeve 10 '.

Yet, above-mentioned probe-type connector since elastomer 30 ' diameter less than sleeve 10 ' internal diameter, thereby elastomer 30 ' lower end is easily in the basal sliding of sleeve 10 ', thereby make the top of elastomer 30 ' inclined, so probe 20 ' can be difficult for extending in the groove 211 ' when pack in housing 11 ' top because of elastomer 30 ' tilts to make elastomer 30 ' upper end, thereby reduces packaging efficiency; On the other hand, probe-type connector 1 ' in use pops one's head in 20 ' when pressing down, because of sleeve pipe 10 ' bottom is a ramp structure, easily make elastomer 30 ' slip and cause elastomer 30 ' bending, thereby can influence elastomer 30 ' performance, reduce the useful life of elastomer 30 '.

The utility model content

The purpose of this utility model is to provide a kind of probe-type connector at the defective that prior art exists, and this probe-type connector is convenient to assembling, and the elastomer life-span is prolonged.

For reaching above-mentioned purpose, the utility model probe-type connector comprises a sleeve, a probe and an elastomer, this sleeve has a housing, housing bottom is connected with the base of a sealing, base and housing surround an accommodation space, one end of housing bends inwards and has extended to form a stopper section, and the stopper section has an opening; Probe has a sliding part and by the convex contact site that stretches out of this sliding part, and sliding part is installed in the housing of sleeve, and contact site is outside opening stretches out sleeve, and the bottom surface of sliding part is concaved with a groove; Elastomer is contained in the housing of sleeve, the end that this housing the is connected with base support portion that extended internally, and support portion has a cavity, and an elastomeric end contacts in the groove of sliding part bottom surface, and the other end is contained in the cavity.

As mentioned above, the utility model probe-type connector relies on the support portion that is provided with on the housing, when probe when case top is packed into, the cavity of support portion is the elastomer bottom fixedly, keep elastomer upright, prevent that elastomer from easily sliding because of the lower end, make things convenient for the elastomer upper end to extend in the groove of probe bottom, and reduce the elastomer degree of crook when housing presses down, thereby can prolong the elastomer life-span at probe.

Embodiment

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

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

Sleeve 10 has a cylindrical circular housing 11, housing 11 bottoms are connected with the base 12 of a sealing, base 12 and housing 11 surround an accommodation space 13, one end of housing 11 bends inwards and has extended to form an annular stopper section 14, stopper section 14 has an opening 15, the other end that housing 11 the is connected with base 12 annular support portion 16 that extended internally, support portion 16 have a cavity 161 that extends downward base 12.

Probe 20 has a cylindrical sliding part 21 and by these sliding part 21 convex cylindrical contact sites 22 that stretch out.Sliding part 21 is installed in the accommodation space 13 of sleeve 10, and the diameter of sliding part 21 greater than the diameter of stopper section 14 middle openings 15 so that sliding part 21 is fastened in the accommodation space 13, the bottom surface of this sliding part 21 is concaved with a groove 211; The diameter of described contact site 22 is less than the diameter of opening 15, and the opening 15 that this contact site 22 passes sleeve 10 stretches out outside the sleeve 10, thereby contact site 22 can electrically connect with external electronic components.

Elastomer 30 is contained in the accommodation space 13 of sleeve 10, and an end of this elastomer 30 contacts in the groove 211 of sliding part 21 bottom surfaces, and the other end is contained in the cavity 161 that support portion 16 surrounded.

When assembling during this probe connector 1, elastomer 30 is contained in the accommodation space 13 of sleeve 10, and elastomer 30 bottoms are contained in the cavity 161 that support portion 16 surrounded.After probe 20 is packed into from housing 11 tops, inwardly pressing housing 11 tops form an annular stopper section 14, provide elastic force upwards with the elastomer 30 of probe 20 bottom grooves 211 butts, stopper section 14 retainings are held the sliding part 21 of probe 20, sliding part 21 is arranged in the accommodation space 13, thereby probe 20 and sleeve 10 are linked together.

When using this probe connector 1, probe 20 is subjected to external force and moves down, probe 20 downward compresses elastomeric 30, sliding part 21 along housing 11 inwalls to lower slider.

In sum, the support portion 16 that the utility model pin type connector 1 relies on sleeve 10 bottoms to be provided with, when probe 20 when pack in housing 11 tops, the cavity 161 of support portion 16 is elastomer 30 bottoms fixedly, keep elastomer 30 upright, prevent that elastomer 30 from easily sliding because of the lower end, makes things convenient for elastomer 30 upper ends to extend in the groove 211, and reduce elastomer 30 degree of crook when housing 11 presses down, thereby can prolong 30 life-spans of elastomer at probe 20.
