Background technology

In fields such as card class connector, battery connectors, to ensure the flatness in conductive terminal contacts portion, it usually needs right The head of conducting terminal carries out precompressed.Under normal circumstances, aperture position of the insulating body provided with terminal groove, terminal groove is provided with compacting Portion, the end of conducting terminal are provided with pre- splenium, after conducting terminal inserts the terminal groove, the precompressed of the conducting terminal end Portion is caught in pressing part prepressing structure formed below in the case where pushing power effect.

And the precompressed position is located at the aperture position of the terminal groove, when active force is larger, the conducting terminal is complete Held entirely by other positions, in the case of connector is less, the unstable situation of conducting terminal fixing easily occur.

Utility model content

In consideration of it, being necessary to provide a kind of electric connector, in the case of precompressed is realized, it is ensured that the fixing of conducting terminal is stable Property.

In order to solve the above technical problems, this application provides a kind of electric connector, including insulating body, be plugged in it is described absolutely The intrinsic conducting terminal of edge, it is characterised in that the conducting terminal includes holding parts, retreaded from the holding parts inverse bending Upwardly extend the elastic arm to be formed, the contact point being formed at the top of the elastic arm, extend obliquely from the elastic arm end The terminal head portion of formation, extend the pre- splenium to be formed from the terminal head portion both lateral sides, the insulating body include pedestal, from The terminal groove for the confession holding parts insertion that the pedestal rear end is opened up and the receiving portion for being formed at the pedestal front end face, institute The pressing part for suppressing the pre- splenium is formed with above the both lateral sides for stating receiving portion.

Preferably, the upper surface of the pressing part is provided with lead-in chamfered diagonally downward.

Preferably, the pedestal upper surface is formed with the extension slot for accommodating the elastic arm.

Preferably, the extension slot and described accommodation section UNICOM, the pressing part are located at the extension slot both sides.

Preferably, the extension slot includes the higher rear top and the relatively low preceding top of horizontal level of horizontal level.

Preferably, the extension slot is to be extended to from the rear top droop formed by the preceding top.

Preferably, it is formed with inverse bending portion between the elastic arm of the conducting terminal.

Preferably, the elastic arm is connected at the inverse bending portion on the rear top.

Preferably, concave up fall into forms hole clipping in the terminal groove, the upward punching press tear of holding parts of the conducting terminal Form the hangnail being caught in the hole clipping.

Preferably, downwardly concave fall into of the terminal groove forms hole clipping, the downward punching press tear of holding parts of the conducting terminal Form the hangnail being caught in the hole clipping.

In order to solve the above technical problems, the electric connector of the application the opening of terminal groove and the pressing part are placed in it is opposite Both direction, the fixation of the conducting terminal by the hangnail and hole clipping except coordinating outer, the pre- splenium and the pressure Portion processed also provides the fixing power of the conducting terminal in front end to ensure that the fixing of conducting terminal is stable.

Embodiment

To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with the application specific embodiment and Technical scheme is clearly and completely described corresponding accompanying drawing.Obviously, described embodiment is only the application one Section Example, rather than whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing Go out the every other embodiment obtained under the premise of creative work, belong to the scope of the application protection.

Refer to shown in Fig. 1 to 4, the electric connector of the application includes insulating body 10, is plugged in the insulating body 10 Interior conducting terminal 20.

The conducting terminal 20 includes holding parts 21, the inverse bending portion 22 for being formed at described one end of holding parts 21, from institute State the end of inverse bending portion 22 extend obliquely the elastic arm 23 of formation, the contact point 24 for being formed at the top of the elastic arm 23, Extend the terminal head portion 25 of formation obliquely from the end of elastic arm 23, extend to be formed from the both lateral sides of terminal head portion 24 Two pre- spleniums 26.The punching press downward or upward of holding parts 21 to form hangnail 27 to tear.

What the confession holding parts 21 that the insulating body 10 is opened up including pedestal 11, from the rear end 12 of pedestal 11 were inserted Terminal groove 14, the receiving portion 131 for being formed at the front end face of pedestal 11, it is formed at the extension slot that the top surface of pedestal 11 is located at 15.The extension slot 15 and the UNICOM of described accommodation section 131, the extension slot 15, which is located above the both sides of described accommodation section 131, to be formed Pressing part 132, the surface of pressing part 132 is provided with lead-in chamfered 133 diagonally downward.The extension slot 15 includes horizontal level Higher rear top 151 and the relatively low preceding top 152 of horizontal level, the extension slot 15 are to tilt to prolong from the rear top 151 Extend the preceding top 152.In the terminal groove 14 upwards or be formed down hole clipping 141 with hangnail 27 described in clamping.It is described Extension slot 15 accommodates the deformation of the elastic arm 23, and relatively low preceding top 152 provides more sufficient deformation for the elastic arm 23 Amount.

The installation principle of the application electric connector is as follows：First the holding parts 21 of the conducting terminal 20 are inserted from rear end 12 In the terminal groove 14, to prevent described lead in the hole clipping 141 that the hangnails 27 of the holding parts 21 is caught in the terminal groove 14 Electric terminal 20 is exited.The elastic arm 23 of the conducting terminal 20 is pressed down on again, now, the pre- splenium 26 of the elastic arm 23 Contacted with inclined lead-in chamfered 133 under the top surface of pressing part 132, as the downward pressure of the elastic arm 23 is increased, The pre- splenium 26 finally breaks through the front-end edge of the pressing part 132 and enters under the reply of elastic force and contact the compacting The lower section in portion 132, in this way, reaching the pre-pressing function of the conducting terminal 20.

The opening of terminal groove 14 is placed in opposite both direction, institute by the electric connector of the application with the pressing part 132 The fixation of conducting terminal 20 is stated in addition to coordinating by the hangnail 27 and hole clipping 141, the pre- splenium 26 and the pressing part 132 also provide the fixing power of the conducting terminal 20 in front end to ensure that the fixing of conducting terminal 20 is stable.

It should also be noted that, term " comprising ", "comprising" or its any other variant are intended to nonexcludability Comprising so that process, method, commodity or equipment including a series of key elements are not only including those key elements, but also wrap Include other key elements being not expressly set out, or also include for this process, method, commodity or equipment intrinsic want Element.In the absence of more restrictions, the key element limited by sentence "including a ...", it is not excluded that wanted including described Also there is other identical element in process, method, commodity or the equipment of element.

Embodiments herein is the foregoing is only, the application is not limited to.For those skilled in the art For, the application can have various modifications and variations.It is all any modifications made within spirit herein and principle, equivalent Replace, improve etc., it should be included within the scope of claims hereof.
