Abstract
The utility model discloses a forced solder terminal of exempting from, including the terminal body, the terminal body includes end portion and connecting portion, end portion is from down insert district, patch area, transition district, keep district and intensity district supreme divideing into in proper order in advance, be equipped with elliptical aperture broad in the middle small in ends in the transition district, the patch area all is equipped with the bellmouth orifice that one end is big, one end is little in the district with keeping, the both ends of distinguishing the elliptical aperture in the transition are connected to the tip and the tip that keeps distinguishing the bellmouth orifice of patch area bellmouth orifice. Adopt behind this technical scheme: 1, the terminal is more firm the grafting after -fixing. 2, the terminal inserts the back, and the atress of distinguishing, last the district in patch area, transition is more even. 3, even the terminal is owing to shake the constraint that has broken away from lasting district, the patch area is distinguished with the transition still can provide the powerful effort, firmly fixes the terminal, can not produce contact failure or direct idle problem.
Description
Technical field
The utility model is related to automotive connector field, and more particularly, to one kind is forced solder terminal is exempted from.
Background technology
What electric power connector was connected with PCB is broadly divided into press-fit (crimping), through hole solder (welderings
Connect) and SMT (surface mounting technology).Wherein press-fit types connector is with its low cost, high efficiency, simple to operate, reliability
It is high and be widely used in the industries such as communication, computer.Wherein fish eyelet terminal is the terminal structure being most widely used.
Flake terminal is made up of end head and connecting portion two parts；Wherein end portion is into five areas, as shown in figure 1, end
Head is followed successively by from bottom to top：Pre-inserted area 1, insert district 2, transition region 3, holding area 4 and intensity region 5.From the end head shown in Fig. 2
Pressure curve and contact engaging and separating force curve map can show that the afterbody of insert district occurs the primary peak of pressure, the tail of holding area
There is the secondary peak of pressure in portion, and the falling of pressure is occurred at transition region.In addition the maximum of withdrawal force occurs in holding
Area, in transition region, the value of withdrawal force is minimum.And existing flake terminal end head design be all it is small in ends broad in the middle,
This is resulted in use, due to reasons such as vibrations, once terminal is overcome after the maximum contact engaging and separating force of holding area, flake
Terminal easily loosens or directly comes off, and it is bad or cannot normal work that this will result in termination contact.
Utility model content
In order to overcome the shortcomings of that existing terminal is present, the utility model is carried by changing the structure of existing terminal endoporus
Formula is more rigidly pressed into for a kind of connection exempt from solder terminal.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions：One kind is forced to exempt from welding ends
Son, including terminal body, the terminal body is divided into from bottom to up pre-inserted area, insert district, transition region, holding area and intensity
Area；Elliptical aperture broad in the middle small in ends is provided with the transition region；It is equipped with that one end is big, one end in the insert district and holding area
Little bellmouth orifice；The small end of the insert district bellmouth orifice and the small end of holding area bellmouth orifice are connected to the two of transition region elliptical aperture
End.
After using the technical solution of the utility model, because the bellmouth orifice of insert district is gradually contracted from insert district to transition region
Little, with the lasting insertion of terminal, the afterbody of insert district occurs the primary peak of pressure, and bellmouth orifice herein is due to inside
Shrink, taper into, the less reaction in aperture is bigger.In transition region, pressure has certain returning relative to the pressure of primary peak
Fall, and the aperture of elliptical aperture herein becomes big, reaction force can reduce.There is pressure near holding area and the junction of transition region
Secondary peak, thus bellmouth orifice locate gradually to increase backward, and aperture is bigger, and reaction force is less.
After using above-mentioned technical proposal, 1, terminal it is fixed more firm after grafting.2nd, after terminal insertion, in insertion
Area, transition region, continue area and be more uniformly stressed.Even if the 3rd, terminal due to vibrations departing from lasting area constraint, insert district and
Transition region can still provide strong active force, and terminal is fixedly secured, and will not produce loose contact or direct not work
The problem of work.
Further to improve, the top in the pre-inserted area is provided with the symmetrical inclination angle for being easy to pcb board to insert.Inclination angle
Design：1st, terminal is conducive to insert pcb board.The copper platinum layer in PCB aperture is scratched when the 2nd, preventing pre-inserted, the normal work of terminal is affected
Make.

Specific embodiment
The utility model is further described with reference to the mode of specific embodiment：
As shown in Figure 3 and Figure 4, it is a kind of it is forced exempt from solder terminal, including terminal body, terminal body include end head and
Connecting portion；End head is divided into from bottom to up pre-inserted area 11, insert district 12, transition region 13, holding area 14 and intensity region 15.
The pre-inserted area 11 is provided with the symmetrical inclination angle 111 for being easy to pcb board 4 to insert.Two ends are provided with the transition region
Little elliptical aperture 16 broad in the middle；The bellmouth orifice (17,18) that one end is big, one end is little is equipped with the insert district and holding area；Institute
The small end of the small end and holding area bellmouth orifice 18 of stating insert district bellmouth orifice 17 is connected to the two ends of transition region elliptical aperture 16.Fig. 3 institutes
The terminal for showing, the only mode of an end head 1 and a connecting portion 2.According to design needs, connecting portion can with it is many
Individual end head 1 is connected.
As shown in figure 5, when using, connecting portion 2 is fixed in the fixed seat 3 of electric power connector first；Then by pcb board
4 gently contact with each other with the top of end head 1.Because the forced top for exempting from solder terminal is provided with inclination angle 111, pcb board 4
Easily can contact with end head 11, and then realize pre-connection, finally again press-in by way of pcb board 4 is pushed, make
It is contacted completely with the forced end head 1 for exempting from solder terminal, and the purpose welded is exempted from realization.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model
Other various forms of products, however, make any change in its shape or structure, it is every with same as the present application or phase
Approximate technical scheme, all falls within protection domain of the present utility model.
