Description
The relevant a kind of electric connector of the utility model refers to that especially a kind of tool locked instrument is to be positioned at electric connector the electric connector on the printed circuit board (PCB).
The existing electric connector relevant with this case is respectively equipped with usually electric connector is positioned at the buckle pieces (card base) of printed circuit board (PCB) and has and locks threadably and fastening locking member.Related art sees also United States Patent (USP) the 5th, 709, and 556 and 4,874, No. 336, and Taiwan patent application the 81st, 212,364 and 83,200, No. 254 etc.These existing buckle pieces and locking member branch are arranged, and need a fairly large number of part to finish function, cause manufacturing and assembling process operation more relatively, are unfavorable for reducing production costs and simplifying working process.In addition, because locking member self does not have elastic component, the elastic part of class that often needs to add in addition spring washer when locking is to increase auto-lock function.These all inconvenience also cause whole electric connector structure complexity, are unfavorable for the design of this light and handyization of electronic product.
The purpose of this utility model is to provide a kind of electric connector, the locked instrument of this electric connector is integrated buckle pieces mutually with the function of screw-threaded coupling member, and increase auto-lock function by the ad hoc structure design, the function optimization, designs simplification, the processing procedure that make whole electric connector reduce and the effect of manufacturing cost reduction to reach.
The utility model electric connector includes insulating body, the joint face that it is provided with the interface that connects with outside butt connector and links to each other with interface and be connected with group with printed circuit board (PCB).Wherein offer the plurality of terminals accepting groove backward, and the body that insulate the certainly wall relative with joint face offers at least one winding space downwards, and it is provided with a through hole that leads to the winding space at least at the insulating body interface from the body interface that insulate.In addition, contain snapping member in this winding space, this snapping member comprises card base and fixed part.Card base bifurcated and have elasticity, it passes insulating body from top to bottom and exposes its head, when electric connector is installed to printed circuit board (PCB), this head can snap onto electric connector many bending structures that the printed circuit board (PCB) fixed part extends from the root of card base, it roughly comprises two parts, wherein the position of the corresponding insulating body through hole of first is provided with a group connecting part, second one by being attached to the inwall that has through hole in winding space, first and second portion fuse and also these two parts between a spacing is arranged, form locked instrument by a locking member and above-mentioned snapping member in addition, wherein this locking member has the assembly portion that matches with group connecting part, when when assembling so that locked instrument is reached auto-lock function.
Because adopt such scheme, the locked instrument of this electric connector is integrated the function of buckle pieces and screw-threaded coupling member rightly, and increase auto-lock function, to have reached the function reinforcement that makes whole electric connector and more optimized structure by the ad hoc structure design.
The utility model is described in further detail below in conjunction with drawings and Examples, wherein:
Fig. 1 is the three-dimensional exploded view of the utility model electric connector.
Fig. 2 is the three-dimensional assembly diagram of electric connector shown in Figure 1.
Fig. 3 is that the utility model electric connector is installed in behind the printed circuit board (PCB) partial sectional view along A-A line shown in Figure 2.
Fig. 4 is that the utility model electric connector is along B-B line partial sectional view shown in Figure 3.
Fig. 5 is the stereogram of the utility model electric connector locked instrument.
See also first and shown in Figure 2, the utility model electric connector includes microscler insulating body 1, the appropriate location offers plurality of terminals accepting groove 11 backward from interface in the insulating body 1, number of metal conducting terminal (not shown) is housed in the corresponding plurality of terminals accepting groove 11, insulating body 1 end respectively offers a winding space 10 downwards from end face, this winding space 10 is made up of passage 12 and alcove 13 in the present embodiment, and has a through hole 14 and the alcove 13 in winding space to interlink.The locked instrument 3 of the utility model electric connector is housed in this winding space 10.
See also shown in Figure 5ly, the locked instrument 3 of the utility model electric connector includes snapping member 4 and locking member 5.This snapping member 4 comprises card base 30 and fixed part 34.Card base 30 has the structure of elasticity bifurcated, it inserts insulating body 1 and exposes snapping head 31, establish head hangnail 43 on the snapping head 31, when the snapping hole 20 on the insertion printed circuit board (PCB) 2, this snapping head 31 can be detained and be held in this snapping hole 20 (as shown in Figures 3 and 4), card base 30 roots also are provided with root hangnail 33, so that card base 30 can be buckled in the passage 12 of insulating body 1 admittedly; Fixed part 34 extends from card base 30 root one, it comprises the first that offers helicoid group connecting part and is provided with the second portion of avoiding the yielding hole 36 of interfering with locking member 5, via twice bendings, and these two parts roughly are parallel to each other and leave spacing between the two between these two parts.The group connecting part 35 of fixed part 34 protrudes a cylinder 37 from first, offers a helicoid circular hole in the cylinder 37 to form.The second portion of fixed part 34 offers on the winding space inwall of through hole 14 by being attached to insulating body.In addition, in the present embodiment, locking member 5 comprises columniform assembly portion 51 and stop section 50, and the diameter of assembly portion 51 is littler and have the screw thread that matches with group connecting part 35 than the through hole 14 of insulating body 1, and stop section 50 is bigger than the through hole 14 of insulating body 1.In assembling during connector, the assembly portion 51 of locking member 5 to be passed the through hole 14 of aperture 40 on the metal-back 4 and insulating body 1 and is screwed into group connecting part 35, stop section 50 is then stayed outside the through hole 14.When tightening locking member 5, force fixed part 34 that certain elastic deformation takes place, and make its first small strain take place to the inwall that through hole 14 is arranged of insulating body 1 alcove 13, thereby produce roughly along locking member 5 axis directions and deviate from the elastic force of aforementioned inwall, so that produce coupling mechanism force between the screw thread of locking member 5 and locked instrument 3, so reach the function of self-locking.
