Abstract

The utility model relates to the technical field of electronic connectors, in particular to a double-head spring type contact probe which comprise a tube body, probe axes and springs, wherein a blind hole is respectively formed at the two ends of the tube body, the number of the probe axes and the springs is two, a spring and a probe axis are arranged in each bind hole of the tube body, one end of each of the springs is in contact with the bottom of each the blind holes, the other end of each of the springs are in contact with the end surfaces of the probe axes, and the probe axes are riveted with the open ends of the blind holes of the tube body into a whole; the movable probe axes are arranged at two ends of the contact probe, which can meet the requirement of application situations where probe axes are needed at two sides; in addition, a limiting step is arranged on the outer circumference of the tube body, a seal washer can be arranged at the limiting step, in order to avoid external dust, oil or water from entering the electronic equipment and prevent the electronic equipment from being damaged; moreover, the bottoms of the probe axes are arranged to be inclined planes, so that the probe axes are inclined when being moved, the contact surface with the inner tube is increased, further, the value of resistance between the probe axes and the inner tube is reduced, and the conduction stability of the connector is enhanced.

Description

Double end spring contact probe

Technical field:

The utility model relates to the electric power connector technical field, refers in particular to a kind of double end spring contact probe.

Background technology:

Along with science and technology development, digital product emerges one after another, has been widely used such as portable sets such as digital camera, Digital Video, mobile phones, and the power supply that this type of portable set adopts mostly is rechargeable battery repeatedly greatly, therefore, rechargeable battery also is widely used.Generally contact between battery and the power consumption equipment by connector, existing connector commonly used generally comprises needle shaft, interior pipe and spring, needle shaft and interior pipe, spring riveted are one, needle shaft can move both vertically up and down under the effect of external force and spring, during use, needle shaft directly contacts with power supply, as the usefulness of electric power conduction.But in some use occasion, we wish that the two ends of connector all have probe, and are more convenient to use like this, have needle shaft but existing connector all is an end, can't satisfy the demand.At present, can only adopt two connectors just can meet the demands, the bottom contact of two connectors, the needle shaft of connector contacts with Devices to test with power supply respectively, but, the sealing of the joint portion of two connectors is difficult to guarantee, the content that extraneous dust, oil or water is easy to enter electronic equipment, and then damage electronic equipment.

The utility model content:

The purpose of this utility model is exactly to provide a kind of double end spring contact probe at the deficiency of prior art existence.

To achieve these goals, the technical solution adopted in the utility model is: double end spring contact probe, comprise body, needle shaft and spring, described body two ends respectively offer a blind hole, described needle shaft and spring respectively are two, all are provided with a spring and a needle shaft in each blind hole of body, and spring one end contacts with the blind hole bottom, the spring other end contacts with the end face of needle shaft, and the blind hole openend riveted of needle shaft and body is an one.

Described body excircle is provided with a limited step.

The end face that described needle shaft contacts with spring is the plane.

The end face that described needle shaft contacts with spring is the inclined-plane.

The end face of the exposed junction of described needle shaft is a hemisphere face.

Described body excircle is provided with a bulge loop.

The beneficial effects of the utility model are: because two ends of the present utility model all have movable needle shaft, can satisfy all use occasions of needs needle shaft of both sides, and, the body excircle is provided with a limited step, during use, can seal washer be set at the limited step place, can prevent that so extraneous dust, oil or water from entering in the electronic equipment, can not make electronic equipment impaired; In addition, the bottom of needle shaft is made as the inclined-plane, makes that needle shaft can run-off the straight in when action, increases the contact area with interior pipe, and then reduces the resistance between needle shaft and the interior pipe, increases the stability that connector conducts.

Embodiment:

See shown in Fig. 1 to 4, this is an execution mode 1 of the present utility model, it comprises body 1, needle shaft 2 and spring 3, described body 1 two ends respectively offer a blind hole 1a, described needle shaft 2 and spring 3 respectively are two, all be provided with a spring 3 and a needle shaft 2 in each blind hole 1a of body 1, spring 3 one ends contact with blind hole 1a bottom, spring 3 other ends contact with the end face of needle shaft 2, the end face that described needle shaft 2 contacts with spring 3 is the inclined-plane, needle shaft 2 is an one with the blind hole 1a openend riveted of body 1, described body 1 excircle is provided with a limited step 1b, during use, can seal washer be set, can prevent extraneous dust like this at limited step 1b place, oil or water enter in the electronic equipment; The end face of the exposed junction of described needle shaft 2 is a hemisphere face; Described body 1 excircle is provided with a bulge loop 1c, and the shape of bulge loop 1c can be U type or V-type, and bulge loop 1c can play the effect that prevents that body 1 from sliding.

See Fig. 5, this is an execution mode 2 of the present utility model, different with execution mode 1 is, in the present embodiment, the end face that described needle shaft 2 contacts with spring 3 is the plane, it is not that other structure is identical with the structure of execution mode 1, repeats no more here in the very high electronic equipment that this connector can be used in that electrical conductivity requires.

The above execution mode, it is better embodiment of the present utility model, be not to be used for limiting practical range of the present utility model, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model patent claim.
