Description
Affiliated technical field
The utility model discloses a kind of power connector, particularly a kind of plug-in type female end power connector.
Background technology
Along with development of electronic technology, the kind of electrical equipment and its proportion shared in people's life are increasing, mostly compact electric apparatus is to adopt the low-tension supply power supply, converts civil power to low-voltage DC by external transformer, again by powering in the power connector input electrical equipment.Mostly power connector of the prior art is to adopt plug-in type to connect, the female end power connector is to be plugged with an electrical connection post in an insulating body, be electrically connected the post next door and also be plugged with the electrical connection shell fragment, during use, be electrically connected post and be electrically connected shell fragment and be connected on the positive pole and negative pole of power supply, in the plug of connector male head and female, be electrically connected shell fragment and cause short circuit phenomenon between the post with being electrically connected easily.In addition, be electrically connected post and when producing, set in advance in insulating body, after the frequent plug, be electrically connected post and be easy to generate loosening, pine and move back, perhaps, and produce dislocation etc., influence product quality and use owing to use incorrectly.
Summary of the invention
Cause short circuit easily at the above-mentioned power connector of mentioning of the prior art, being electrically connected post is easy to generate loosening, pine and moves back, influence shortcomings such as product quality and use, the utility model provides a kind of new power connector, it has the block installing hole in the insulating body side, is fitted with insulating spacer in the block installing hole, has breach on the insulating spacer, breach is inserted into and is electrically connected the post place, and the last relevant position that is electrically connected post is provided with circular protrusion.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of power connector, comprise insulating body, be electrically connected post, be electrically connected shell fragment, shield shell, being electrically connected post is plugged in the main body, being electrically connected shell fragment is inserted in the main body, shield shell is installed in the insulating body outside, and the main body side has the block installing hole, is fitted with insulating spacer in the block installing hole, have breach on the insulating spacer, be electrically connected post and be inserted in the breach.
The technical scheme that its technical problem that solves the utility model adopts further comprises:
Be provided with projection with the insulating spacer cooperation place on the described electrical connection post.
Described projection in the form of a ring.
Described electrical connection post engages for vertical with insulating spacer.
The beneficial effects of the utility model are: the utility model is simple in structure, in the time of can effectively preventing the power connector plug, being electrically connected shell fragment contacts with the electrical connection post by auxiliary member (block), the short circuit phenomenon that causes, simultaneously, it is more firm that the electrical connection post is installed, and increased the quality and the result of use of product.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Fig. 1 faces perspective view for the utility model decomposing state.
Fig. 2 is the utility model decomposing state rear perspective structural representation.
Fig. 3 is the utility model decomposing state plan structure schematic diagram.
Fig. 4 is the utility model decomposer left side TV structure schematic diagram.
Among the figure, the 1-main body, shielding case before the 2-side shielding case, 3-, 4-is electrically connected post, and 5-is electrically connected shell fragment, 6-insulating spacer, 7-block jack, 8-projection, 9-installing hole, 10-mounting groove, 11-breach.
Embodiment
Present embodiment is the utility model preferred implementation, and other all its principle is identical with present embodiment or approximate with basic structure, all within the utility model protection range.
Please referring to accompanying drawing 1 to accompanying drawing 4, main body 1 of the present utility model is identical with power connector main body of the prior art, it is to adopt the rectangular shape that is similar to that insulating material makes, main body 1 front end is equipped with preceding shielding case 3, side shielding case 2 is installed above the main body 1, and side shielding case 2 is enclosed on three sides of main body 1.Have circular mounting hole 9 in the middle of the main body 1, be equipped with in the middle of the circular mounting hole 9 and be electrically connected post 4, be used for being connected, be electrically connected the electrode of post 4 for the power supply input with the power connector male that matches.On the main body 1,9 next doors, circular mounting hole that are electrically connected post 4 are installed have mounting groove 10, mounting groove 10 is interconnected with installing hole 9, is fitted with in the mounting groove 10 and is electrically connected shell fragment 5, is electrically connected shell fragment 5 another electrode for the power supply input.In the present embodiment, main body has block jack 7 on 1 side, be fitted with insulating spacer 6 in the block jack 7, insulating spacer 6 is made for insulating material, has on the insulating spacer 6 and is electrically connected the breach 11 that post 4 matches, when insulating spacer 6 inserts in the block jacks 7, breach 11 is inserted into and is electrically connected on the post 4, breach 11 degree of depth, are electrically connected post 4 and are trapped in fully in the breach 11 after the installation greater than being electrically connected post 4 diameters.Be electrically connected on the post 4 and be provided with circular protrusion 8 with corresponding position, insulating spacer 6 installation sites, when insulating spacer 6 inserted in the block jack 7, breach 11 retainings of insulating spacer 6 made electrical connection post 4 be difficult for deviating from main body 1 at circular protrusion 8 places.After side shielding case 2 was installed, side shielding case 2 can keep off at block jack 7 places, and insulating spacer 6 can not deviate from block jack 7.
The utility model has additional an insulating spacer 6 on the common power connector, on the one hand, when power connector used, when the power connector male was inserted female, insulating spacer 6 can block and be electrically connected post 4, makes power connector not fragile; On the other hand, when the power connector male plugs use for a long time, that insulating spacer 6 is easy to generate is loosening, pine moves back, thereby to produce short circuit possible with being electrically connected shell fragment in using to have eliminated the electrical connection column length phase, even when being electrically connected post 4 pine move back in plug is used, the electrical connection post also can and not be electrically connected shell fragment with housing and cause short circuit, has increased the fail safe of using.
The utility model can be widely used in the various compact electric apparatus that need external power supply power supply.
