In order to realize this purpose, the technical solution of the utility model is as follows: a kind of have the electric connector splitting groove structure
Jack contact, includes, jack contact body, described jack contact body series in order to combine contact pin contacting piece body with
Realize electrical connection, described jack contact body has and splits groove.Described jack contact body series is tapered by be sequentially connected
Section, divergent segment and straightway composition, wherein, described converging transition system is in the stem of described jack contact body, and described directly
Line segment system is in the afterbody of described jack contact body；Also, the diameter system of the junction of described converging transition and described divergent segment
Diameter less than described contact pin contacting piece body so that described junction and described contact pin contacting piece body can be with the sides of interference
Formula matches.
As the preferred version of a kind of electric connector jack contact having and splitting groove structure, described converging transition has relatively
The first end and the second end, the diameter system of described converging transition is gradually reduced to its second end from its first end；Described divergent segment has
Having the first relative end and the second end, the diameter system of described divergent segment is gradually increased to its second end from its first end；Described directly
Line segment has the first relative end and the second end, and the diameter of described straightway is the most constant to its second end from its first end；And,
First end system of the second end of described converging transition and described divergent segment is smooth excessive to be connected, and the second end of described divergent segment is with described
The smooth excessive connection of first end system of straightway.
As the preferred version of a kind of electric connector jack contact having and splitting groove structure, the first end of described converging transition
Diameter system more than the diameter of the second end of described divergent segment, the diameter system of the second end of described divergent segment connects more than described contact pin
The diameter of contact element body.
As the preferred version of a kind of electric connector jack contact having and splitting groove structure, described in split groove system from described gradually
First end of contracting section begins to extend to the second end of described divergent segment.
Compared with prior art, advantage of the present utility model at least that: (1) is owing to there being the design of converging transition so that insert
Hole contact has guide effect.(2) owing to there being the design of junction, it is ensured that jack contact body and contact pin contacting piece body
Reliable contacts.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of this utility model one embodiment.
Detailed description of the invention
Combine accompanying drawing below by specific embodiment this utility model is described in further detail.
Referring to Fig. 2, shown in figure is a kind of electric connector jack contact having and splitting groove structure.Its structure comprises
Have, jack contact body 1.Described jack contact body 1 is to combine contact pin contacting piece body (not shown) with reality
Now electrically connect.Vertically, described jack contact body 1 is by the converging transition 11 being sequentially connected, divergent segment 12 and straightway
13 compositions.Wherein, described converging transition 11 is the stem being in described jack contact body 1, and described straightway 13 is to be in
The afterbody of described jack contact body 1.Specifically, described converging transition 11 has the first relative end and the second end, described
The diameter system of converging transition 11 is gradually reduced to its second end from its first end.Described divergent segment 12 has the first relative end and
Two ends, the diameter system of described divergent segment 12 is gradually increased to its second end from its first end.Described straightway 13 has relative
First end and the second end, the diameter of described straightway 13 is the most constant to its second end from its first end.Described converging transition 11
First end system of the second end and described divergent segment 12 is smooth excessive to be connected, the second end of described divergent segment 12 and described straightway 13
The smooth excessive connection of the first end system.
Also, the diameter system of the junction 112 of described converging transition 11 and described divergent segment 12 is less than described contact pin contacting piece originally
The diameter of body so that can match with described contact pin contacting piece body in the way of interference in described junction 112.In order to improve
Contact reliability, described junction 112 is matsurface with the face that coordinates of described contact pin contacting piece body or has salient point.Described tapered
The diameter system of the first end of section 11 is more than the diameter of the second end of described divergent segment 12, the diameter of the second end of described divergent segment 12
System is more than the diameter of described contact pin contacting piece body.It should be noted that owing to described jack contact body 1 is homogeneous by thickness
Thin metal machining obtain, therefore, diameter here can be understood as internal diameter, it is understood that for external diameter.
Have on described jack contact body 1 and split groove 10.Described groove 10 of splitting is that the first end from described converging transition 11 begins
Extend to the second end of described divergent segment 12 so that described jack contact body 1 has radially inner stress and elasticity, really
Protect described jack contact body 1 to completely attach to described contact pin contacting piece body.
Design based on described converging transition 11, it is ensured that being properly inserted of described contact pin contacting piece body, it is to avoid pernicious slotting
The damage entered and cause, secondly also ensures that described contact pin contacting piece body can smooth entrance and described knot during inserting
The stable gentle contact of 112 at conjunction, it is to avoid rigid mechanical friction, improves the service life of contact.Based on described junction 112
Design, it is ensured that contact reliable and stable the most impaired.
In conjunction with above-mentioned, it can be seen that the present embodiment need not complicated loaded down with trivial details accessory, complete independently connects transfer function, tool
Standby guides, connect, contact, transmit, the multiple electrical communications characteristic such as protection, accomplish electric property, physical property and environment adaptation
Taking into account of performance.Leading indicator is excellent: current-carrying capacity: can >=65A；Running voltage: 10kV/DC can be surpassed；Insulation resistance: >=5000M
Ω；Mechanical life: 10000 times；It is greatly improved adapter core number density.
Below only have expressed embodiment of the present utility model, it describes more concrete and in detail, but can not therefore and
It is interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, not
On the premise of departing from this utility model design, it is also possible to making some deformation and improvement, these broadly fall into guarantor of the present utility model
Protect scope.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
