Abstract
The invention discloses an elastic contact element of an electric connector. The elastic contact member comprises a butting guide region (3) and a plugging contact region (4), wherein the inner diameter of the part, which is positioned at a plugging inlet, of the elastic contact element (1) is slightly large and the part is open to form the butting guide region (3) which plays a role in guidance when a contact pair is butted or plugged; the rear part of the butting guide region (3) is provided with the plugging contact region (4) where a butting terminal (2) is elastically and closely contacted with the elastic contact element (1) when the contact pair is plugged; and compared with the outer diameter of the butting terminal (2), the inner diameter of the plugging contact region (4) can guarantee sufficient interference magnitude in the plugged contact pair. The elastic contact element is simpler than a twisted elastic pin, a crown spring jack and a wire spring jack in forming; the problem of poor contact of a slot type jack caused by releasing internal stress can also be avoided during butting; and contradiction between reliability and price of the contact pair can be effectively overcome.
Description
Technical field
The present invention relates to a kind of resilient contact of electric connector.
Background technology
The resilient contact of electric connector is the vital part of electric connector, has obtained being extensive use of in various connectors.Resilient contact commonly used now mainly contains stranded elastic contact pin, hat spring socket, wire spring socket and several forms of open flume type elastic hole.The open flume type elastic hole is owing to moulding process simply is widely used, and all the other several resilient contacts only just are being used the higher occasion of connection request owing to the moulding process more complicated.Since connector contact to connection reliability be the most important performance of connector, thereby it is always by extensive concern and attention, also is the hard nut to crack in the connector quality control.
Summary of the invention
The objective of the invention is: the resilient contact that a kind of electric connector is provided, this resilient contact is simpler than stranded elastic contact pin, hat spring socket and wire spring socket in moulding, the time can avoid the open flume type jack again because internal stress discharges the loose contact problem that causes in butt joint, can effectively solve contact to reliability and the contradiction between the price.
Technical scheme of the present invention is: a kind of resilient contact of electric connector, it comprises the butt joint boot section, plugs together the contact zone, it is bigger open-shaped that described resilient contact is positioned at the internal diameter that plugs together the porch, constitute when contact to docking the butt joint boot section that the energy tool plays guiding function when plugging together; The rear portion of described butt joint boot section is provided with the contact zone that plugs together that the butt joint terminal contacts with resilient contact generation elastic tight when contact plugs together finishing; The outside dimension of the described internal diameter size that plugs together the contact zone and butt joint terminal mutually specific energy guarantee to plug together the back contact between enough magnitudes of interference are arranged.
Described butt joint boot section all is that metal is carried out the plastically deforming area that plastic deformation is handled with plugging together the contact zone.
Advantage of the present invention is:
1, the resilient contact of electric connector of the present invention according to the plastic deformation of metal principle, provides a kind of moulding process simple resilient contact design.This resilient contact is simpler than stranded elastic contact pin, hat spring socket and wire spring socket in moulding, the time can avoid the open flume type jack again because internal stress discharges the loose contact problem that causes in butt joint, can effectively solve contact to reliability and the contradiction between the price.
2, the present invention is a kind of at the resilient contact that compares favourably with stranded elastic contact pin on the contact performance, can be identical with the open flume type elastic hole on moulding process.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of resilient contact of the present invention;
Fig. 2 is the structural representation of butt joint terminal;
Fig. 3 is for contacting plugging together procedure chart;
Fig. 4 is for contacting plugging together docking scheme.
Wherein: 1 resilient contact; 2 butt joint terminals; 3 butt joint boot sections; 4 plug together the contact zone; 5 plastically deforming areas.
Embodiment
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, a kind of resilient contact of electric connector, its function distinguishing is for butt joint boot section 3 and plug together contact zone 4, and the functional areas of resilient contact 1 all need to adopt certain way (heat treatment, aging or flow harden etc.) allow metal generation plastic deformation, avoid contact in use or put procedure, Stress Release to take place, and then cause contact to lose efficacy.
Contact is to docking when plugging together, butt joint terminal 2 contacts with butt joint boot section 3 earlier, butt joint boot section 3 open-shaped (bell mouth shape), guarantee that resilient contact 1 has the good guiding function when plugging together, avoid its displacement deformation (distortion that can not recover fully) that its elastic limit takes place to surpass in the process of plugging together, and then cause losing efficacy; Contact to finish plug together after, flexible tight the contact takes place plugging together contact zone 4 in butt joint terminal 2 and resilient contact 1, guarantee to contact between have good electrical contact, for the better quality of product provides reliable guarantee.
Contact to the process of plugging together as shown in Figure 3, when butt joint terminal 2 enters resilient contact 1 butt joint boot section 3, because the flexible terminal design has enough displacement amount of redundancys, make resilient contact 1 have the good guiding function, so when butt joint terminal 2 still can guarantee not being damaged property injury of flexible terminal when eccentric phenomena occurring, guaranteed contact between connection reliability.
As shown in Figure 4, contact to finish plug together after, because the basic size identical (with reference to the Φ A of figure 1 and Fig. 2) of the internal diameter that plugs together contact zone 4 of resilient contact 1 and the external diameter that docks terminal 2, so can guarantee fully to contact between two contacts (slight strain has taken place resilient contact 1), guaranteed contact between have the excellent contact performance, for the better quality of product provides reliable guarantee.
When carrying out terminal design, need to guarantee contact between have enough magnitudes of interference, with guarantee to contact between have enough positive pressure, guarantee contact between contact resistance meet the demands.
In the present embodiment, the butt joint boot section of resilient contact 13 and plug together contact zone 4 and be designed to circular configuration, but when it is designed to other shape, also belong to the scope of the present invention.
Should be pointed out that for the present invention also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned execution mode through proving absolutely.The foregoing description is as just explanation of the present invention, rather than limitation of the present invention.In a word, protection scope of the present invention should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
