Abstract
The utility model discloses a probe-type spring electronic connector which comprises a metal sleeve shell, a probe and a pressure spring; the upper end of the metal sleeve shell is provided with a hole; the lower end of the probe is nested in the metal sleeve shell through a hole on the upper end of the metal sleeve shell and is propped against the side wall and the upper end of the metal sleeve shell; the pressure spring is arranged in a cavity of the metal sleeve shell, and both ends thereof are respectively propped against the bottom part of the metal sleeve shell and the bottom part of the probe; and the connector is characterized in that the upper end of the metal sleeve shell is provided with an elastic contact pin, the contact pin is provided with a contact, and the contact contacts with the probe. The utility model thoroughly avoids the power-off phenomenon of the probe connector and can basically reduce the contact resistance of the probe-type connector to zero.
Description
Technical field
The utility model relates to the electric power connector field, is specially a kind of probe-type spring electric power connector, and it is mainly used in being connected of electrical equipment main and battery, also can be used for the connection between other electronic devices and components.
Background technology
General communicating terminal, as the main frame and being connected of battery of mobile phone, cordless telephone be to connect by the spring-piece type connector.But the spring-piece type connector has the little and difficult adjusting of elastic force, and it is big to take up room, and is difficult to miniaturization.And existing spring electric power connector is the continuous connection realization conduction by probe body and metal casing sidewall and sheath body upper end, and be rigidly connected between the two, there is not telescopic elastic force stroke each other, so this connection is unsettled, the disconnection power down phenomenon that can cause moment, promptly contact resistance becomes quite big moment.This is popular in the present common fault of the thimble-type connector of electron trade, especially connect big electric current (greater than 5 amperes) by the time, the thimble-type electric power connector cost that becomes is quite high, and poor reliability.
The utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, proposes a kind of probe-type spring electric power connector, thoroughly stops the outage phenomenon of probe connector, and can basically the contact resistance of probe-type connector be reduced to 0.
The technical solution adopted in the utility model is as follows: a kind of probe-type spring electric power connector, comprise metal casing, probe and stage clip, metal casing upper end perforate, the probe lower end is nested in the metal casing by the hole of metal casing upper end, stage clip is located in the hole of metal casing, two ends respectively with metal casing hole bottom and probe base apical grafting, the metal casing upper end is provided with the elasticity haptic element, haptic element is provided with the contact.
As improvement, described metal casing and probe are cylinder.
As improvement, described probe stretches out the part of metal casing, and its external diameter increases from the bottom to top, and during the probe compression, the contact contacts with probe.
As improvement, below the elasticity haptic element, the metal casing upper end has closing in, passes through for the probe upper end in the middle of closing up.
The beneficial effects of the utility model are: add the metal haptic element in the sheath body upper end, the contact is pressed in detecting probe surface and is attached thereto and connects when probe compresses in the sheath body hole, can keep stable connection always, thoroughly stop the outage phenomenon of probe connector, and can basically the contact resistance of probe-type connector be reduced to 0.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Referring to Fig. 1, in an embodiment of the present utility model, electric power connector comprises probe 1, metal casing 2, stage clip 3.Probe 1 is divided into end of probe 11, probe neck 12 and probe body 13 again, end of probe and neck external diameter are identical, are a cylinder, stretch out outside metal casing by the opening on the metal casing, probe body is set in the metal casing, contacts with roof with the sidewall of metal casing.Metal casing 2 whole cylinder housings for sealing, metal casing upper end perforate is provided with and closes up 21, passes through for probe.The metal casing upper end is equipped with elasticity haptic element 22, is provided with contact 23 at elasticity haptic element end, and contact 23 closely contacts with probe.Stage clip 3 is located in the cavity 24 of metal casing, two ends respectively with metal casing bottom and probe base apical grafting.
In second embodiment of the present utility model, electric power connector comprises probe 1, metal casing 2, stage clip 3.Probe 1 is divided into end of probe 11, probe neck 12 and probe body 13 again, the end of probe external diameter is greater than the probe neck, the probe external diameter increases from the bottom to top gradually, end of probe and neck stretch out outside metal casing by the opening of metal casing upper end, probe body is set in the metal casing, contacts with the upper end with the sidewall of metal casing.Metal casing 2 is a cylinder, does not establish closing in, and the upper end is provided with elasticity haptic element 22, is provided with contact 23 at elasticity haptic element plate end, and contact 23 contacts with probe.Stage clip 3 is located in the cavity 24 of metal casing, two ends respectively with metal casing bottom and probe base apical grafting.
During work, probe withstands objects such as battery, is subjected to the influence of external pressure and stage clip elastic force, and probe portion will move back and forth in the metal casing cavity, block probe at any time by the contact on the haptic element, keeps in touch with it, realizes good electrical conductivity.
In embodiment two, the diameter of end of probe is greater than the probe neck, when then probe portion moves down in the metal casing cavity, can guarantee that detecting probe surface can be stablized to touch the contact; When not stressed, the probe neck can be close to the contact because external diameter is less in probe portion, helps moving of probe, has promptly reduced resistance.
