Flag terminal is a kind of conventional binding post, generally for the connection of automobile circuit. As announced a kind of flag terminal with low insert power high extracting power in the application for a patent for invention of Chinese patent literature CN102790301A, its structure as shown in Figure 1, comprise a cable connecting portion and a wiring female terminal, described wiring female terminal comprises a slot, the both sides of described slot are arc tubular sidewall, the bottom of described slot forms the longitudinal gap of twice, and described twice form elastic arm between gap. A kind of flag terminal with low insertion force, high withdrawal force is provided in the prior art, but slot both sides described in this invention are arc tubular sidewall, the arcuate structure of described arc tubular sidewall, in the time connecting and the contact-making surface of wiring male terminal be the lower limb of arc tubular sidewall, only block wiring male terminal with lower limb herein, therefore, in actual use, easily cause wiring male terminal to connect unstable, may in slot, rock situation about even coming off.
Summary of the invention
Technical problem to be solved by this invention is that in prior art, slot arc tubular sidewall can not provide very large contact-making surface, connect unsettled problem, thereby a kind of flag-shaped square tube terminal long-pending compared with large contact surface, stable connection that has is provided.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of flag-shaped square tube terminal, comprises a cable connecting portion and a wiring female terminal, and described wiring female terminal comprises a slot; The vertical sidewall top of described slot both sides be connected with respectively to centre extend, for two elastic linears of coated wiring male terminal, two described elastic linears are provided with two elastic walls between the two ends along grafting direction, between described two elastic linears, form gap.
Described elastic wall is the concave panel to described slot inner recess.
In described slot, the two ends smooth connection of described elastic wall and described elastic linear.
Described smooth connection is for to connect by slope.
In the middle of described slot bottom surface, offer along the slot of grafting direction, have one end and the unsettled elastic arm that slot bottom is connected, the other end is unsettled in described slot, the free end of described unsettled elastic arm is near described slot socket.
Be respectively arranged with the bottom elastic wall to described slot internal protrusion in the both sides of described unsettled elastic arm, described bottom elastic wall is connected by slope with described slot bottom.
Described unsettled elastic arm is along inwardly level and smooth projection of described slot socket direction.
On described unsettled elastic arm, be provided with salient point.
Described gap is 0.4-1mm.
The wiring direction of described cable connecting portion is vertical with the closure of described wiring female terminal.
Technique scheme of the present invention has the following advantages compared to existing technology:
(1) flag-shaped square tube terminal of the present invention, be provided with respectively and extend to centre on vertical sidewall top, the both sides of described slot, for two elastic linears of coated wiring male terminal, described elastic linear is provided with the elastic wall of indent between the two ends along grafting direction, reduce described slot inner space, better coated wiring male terminal, and increase the contact area of upper surface, larger frictional force after inserting into, wiring male terminal is provided, more fastening, stand long-term use, thereby it is fixing unstable to have avoided arc tubular sidewall of the prior art to cause because fixing contact-making surface is little, the situations such as damage easily come off in long-term use.
(2) flag-shaped square tube terminal of the present invention, together with the described elastic wall of the free end of described unsettled elastic arm front end and indent on described elastic linear, reduce to stay in described slot the insertion space of wiring male terminal, in the process of inserting at wiring male terminal, described unsettled elastic arm is moved downward by the extruding of wiring male terminal, after inserting, above wiring male terminal, be close to described elastic wall, there is described unsettled elastic arm to fix because of the elastic force upwards that pressurized produces below, not only vacant what allow wiring male terminal spatially not rock, and can there is larger power to fix, lasting stability, in described slot, the two ends smooth connection of described elastic wall and described elastic linear, has ensured that wiring male terminal, in the time inserting described slot, inserts smoothly by slope, has reduced insertion resistance.
(3) flag-shaped square tube terminal of the present invention, on described slot bottom surface, be provided with unsettled elastic arm, on described unsettled elastic arm, can also be provided with salient point, elastic pressure to its bottom after unsettled elastic arm on described bottom surface has increased wiring male terminal and inserts, ensure the steadiness of its connection, simultaneously after wiring female terminal is connected with wiring male terminal, described salient point coordinates with the retaining groove on wiring male terminal, while extracting, produce larger frictional resistance, further ensured the steadiness after connecting.
(4) flag-shaped square tube terminal of the present invention, described unsettled elastic arm both sides be provided with described bottom elastic wall, described bottom elastic wall and described elastic wall further limit space in socket, form a square gap of passing through that is less than socket, the inclined ramp of described bottom elastic wall front end guides wiring male terminal to move to intermediate gap in the time that wiring male terminal inserts, prevent that it from withstanding on the front end of described unsettled elastic arm, be conducive in the smooth insertion slot of wiring male terminal.
(5) flag-shaped square tube terminal of the present invention, described elastic wall intermediate gap is preferably 0.4-1mm, in the middle of described two-side elastic wall, leave space, in the time inserting wiring male terminal, run in socket in the situation that space being inadequate, can be squeezed and move upward, allow wiring male terminal insert smoothly, and produce afterwards a downward elastic force, better link male terminal in insertion.
