Embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.In the description, same or analogous drawing reference numeral indicates same or analogous parts.The explanation of following reference accompanying drawing to embodiment of the present invention is intended to make an explanation to present general inventive concept of the present invention, and not should be understood to one restriction of the present invention.
In addition, in the following detailed description, for ease of explaining, many concrete details have been set forth to provide the complete understanding to this disclosure embodiment.But significantly, one or more embodiment also can be implemented when not having these details.In other cases, known construction and device diagrammatically embodies to simplify accompanying drawing.
According to general technical design of the present invention, a kind of power connector is provided, comprises: an insulation shell, there are bottom surface, end face and two sides; Three terminals, are arranged in juxtaposition along its length in described insulation shell; A locking mechanism, described power connector and matching connector lock together by outside being configured for separably that be fixed on the surface of described insulation shell; A handle; And a release mechanism, be connected with described handle, and be configured to along with described handle removes the locking of described locking mechanism to described power connector and matching connector relative to described insulation shell mobile.
Fig. 1 illustrates it is the three-dimensional view of power connector according to an embodiment of the invention.In an embodiment of the present invention, disclose a kind of power connector, to be particularly a kind ofly suitable in a narrow space with the micro power connector of high-density arrangement.In the illustrated embodiment in which, this power connector mainly comprises insulation shell 100, three terminal, locking mechanism, release mechanism and handles 300.
Wherein, described locking mechanism 500 comprises: a fixed part 510, is arranged on the outside on the surface of described insulation shell 100, to be arranged on described insulation shell 100 by described locking mechanism 500; A sticking department 530, in the outside of the far-end of described insulation shell 100, to lock with the auxiliary section 210 of described matching connector 200; And a connecting portion 520, the length direction of described insulation shell 100 extends and is connected between described sticking department 530 and fixed part 510.Described fixed part 510 comprises: base portion 513, and the Width of described insulation shell 100 extends, and is arranged on the end face of described insulation shell 100; And at least one installation portion 512, extend to the side of described insulation shell 100 from the end of described base portion 513.
Described sticking department 530 can be locked on the auxiliary section 210 of described matching connector 200, and power connector can not at random be extracted from described matching connector 200, thus guarantees the fastness of connection between power connector and matching connector 200.When described power connector and described matching connector 200 disconnect by needs, handle 300 in locking mechanism interacts with release mechanism, make the far-end of connecting portion 520 and sticking department 530 by jack-up, thus sticking department 530 and auxiliary section 210 are unlocked, power connector is extracted from described matching connector 200.
Fig. 2 and Fig. 3 is profile near the installation portion 512 of power connector according to an embodiment of the invention and fragmentary isometric views respectively; As shown in Figures 2 and 3, in one embodiment of the invention, fixed part 510 comprises: base portion 513, and the Width of described insulation shell extends, and is arranged on the end face of described insulation shell; And at least one installation portion 512, extend to the side of described insulation shell from the end of described base portion 513.The mode that described installation portion 512 combines with buckle is fixed on the surface of two sides being positioned at described insulation shell.
According to a kind of execution mode, be formed with the first groove 107 extended to from described end face described two sides at the near-end of described insulation shell 100, described fixed part 510 is arranged in described first groove 107.
Each described installation portion 512 has an installing hole 511, is provided with an installation projection 101 be combined with described installing hole 511 in described first groove 107.
It is measure-alike that length dimension due to fixed part 510 is decided to be with the width of insulation shell 100, therefore during the described locking mechanism 500 of installation, installation portion 512 is tightly posted by the surface of insulation shell 100, or the bottom of the first groove 107 of the insulation shell 100 that tightly reclines, installation portion 512 is made to be difficult to cross above installation projection 101, in the case, installation portion 512 can be made on the inclined-plane installing the end face of projection 101 and be made for inclination to reduce installing above projection 101 resistance forward, and can guide installation portion 512 slide over described installation projection top and make install projection 101 enter in described installing hole formed buckle connect.Those skilled in the art be arranged on the end face of insulation shell 100, or on the summit portion of the first groove, this do not depart from the scope of the present invention after it is contemplated that and installation portion 512 and the buckle connection of installing between projection 101 slightly being made modification.
Described installing hole 511 and installation projection 101 can be formed as rectangle roughly.
As shown in Figure 4, described release mechanism comprises release mechanism: an actuator lever 400, passes and be connected with described handle 300 in the bottom of described fixed part 510; And a pivot frame 600, to be arranged between described connecting portion 520 and insulation shell 100 and to be connected to the far-end of described actuator lever 400, to make described pivot frame 600 pivotable by pulling described handle 300, thus connecting portion 520 described in jack-up and sticking department 530.Pivot frame 600 comprises: a horizontal part 610 extended along described Width, and the far-end of described actuator lever 400 is connected to described horizontal part 610; And respectively from the two ends of described horizontal part 610 along described two sides to two side direction portions 620 of downward-extension, described two side direction portions 620 are connected pivotally to described two sides of described insulation shell 100 respectively.
Wherein, insulation shell comprises main part 110 and is inserted into the insertion section 120 in described matching connector, and described insertion section 120 forms step with the junction of described main part 110; The side relative with described actuator lever 400 of described horizontal part 610 is provided with assisted activation portion 402, and described assisted activation portion 402 tilts to extend towards described step.
The end face and two sides of the far-end of described insulation shell 100 are formed with the second groove 106, and described pivot frame is arranged in described second groove.
The end face of described insulation shell 100 is formed the 3rd groove 105 extended along its length, and the connecting portion of described actuator lever and described locking mechanism is movably received within described 3rd groove 105.
As shown in Figure 5 and Figure 6, described sticking department 530 has a lock hole 533, described auxiliary section 210 has an engagement protrusion 213 corresponding with the shape of described lock hole 533, and described lock hole 533 is crossed described engagement protrusion 213 and is socketed in described engagement protrusion 213.
According to a kind of execution mode, the end face of engagement protrusion 213 is also tilt, and to guide described sticking department to slide over the top of described engagement protrusion, described engagement protrusion 101 is entered in described lock hole.
