Abstract
The utility model discloses a locked AV terminal. According to the technical scheme, the locked AV terminal comprises a socket and a plug; the plug comprises a pin; the socket comprises an inner wall and an outer wall; an inserting opening for the insertion of the pin is formed on the end part of the inner wall; the inner wall is provided with a reinforcing groove; the reinforcing groove comprises a clamping groove and a communicating groove; the pin is provided with a projection; the communicating groove is arranged from the inserting opening towards the direction of the clamping groove and connects the clamping groove with the inserting opening; and the projection is clamped in the clamping groove after penetrating through the communicating groove. After the socket and the plug are connected with each other, the plug is not liable to slide and cannot break away from the socket in the axial direction, so that tight connection between the socket and the plug is realized, and the problem of unstable connection between the socket and the plug is solved.
Description
Technical field
The utility model relates to a kind of terminal, and more particularly, it relates to a kind of AV terminal.
Background technology
AV terminal claims again composite terminal, is the most general current a kind of video interface, and nearly all television set, video disc player series products have this interface.The RCA terminal that AV terminal is normally yellow, coordinates two redness and white RCA terminal transmission message in addition.
At present, the generally application of AV terminal makes people increasing to its demand.AV terminal need to be fixed on certain position could realize stable connection, but in life production, AV terminal is often fastening not with being connected of plug, if loose contact (as collapse etc.), can cause signal transmission to get loose, as sound equipment sends noise, video image quality fogs, and the serious components and parts that also can cause damage.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of locking-type AV terminal, and this AV terminal has designed the connected mode of socket and plug, has realized stable connection, has solved the problem of socket and plug loose contact.
For achieving the above object, the utility model provides following technical scheme:
A kind of locking-type AV terminal, comprise socket and plug, described plug comprises pin, described socket comprises inner and outer wall, and the end of described inwall forms the insert port of inserting for pin, and described inwall is provided with reinforcing groove, described reinforcing groove comprises draw-in groove and connectivity slot, described pin is provided with projection, and described connectivity slot arranges and is communicated with draw-in groove and insert port to draw-in groove direction from insert port, and described projection is connected in draw-in groove through after connectivity slot.
By adopting technique scheme, when plug is plugged in socket, pin is aimed to insert port, and projection is aimed to connectivity slot and insert, projection is moved to draw-in groove through after connectivity slot, then through further action, it is connected in draw-in groove, projection is fixed in the profile of draw-in groove, be difficult for sliding and cannot axially departing from socket, plug is securely fixed in socket, stable connection and contact are good.
Of the present utility modelly further be set to: described reinforcing groove is L-type.
By adopting technique scheme, reinforcings groove is set to L-type, make projection just in time pass connectivity slot and under, rotate plug and make projection be connected in draw-in groove, thus projection being fixed in draw-in groove tightly, and projection is fixed on draw-in groove end, clamping is convenient, and stable connection and contact are good.
Of the present utility modelly further be set to: described reinforcing groove arranges a plurality of.
By adopting technique scheme, reinforcing groove arranges a plurality of, reinforces groove more, and the stablizing effect that projection is fixed in draw-in groove is also just better.
Of the present utility modelly further be set to: described protruding quantity and the quantity of described reinforcing groove match.
By technique scheme, the quantity of projection is consistent with the quantity of reinforcing groove, and more projection is closely chimeric with draw-in groove, makes both connections more fastening, and signal transmits smooth and easy.
Of the present utility modelly further be set to: being shaped as of described projection is cylindric.
By adopting technique scheme, projection is set to columned benefit and is that the diameter of cylinder is consistent with reinforcing well width, has avoided unnecessary waste of material, is also beneficial to projection and is connected with the stable of draw-in groove.
Compared with prior art, the utility model has the advantage of: by projection with reinforce being connected of groove, connection procedure convenient and, plug is securely fixed in socket, stable connection and contact are well.

Fig. 2 is the socket cutaway view of the utility model locking-type AV terminal embodiment;
Fig. 3 is the vertical view of the utility model locking-type AV terminal embodiment.
Accompanying drawing explanation mark: 1, plug; 2, socket; 3, pin; 4, projection; 5, inwall; 6, connectivity slot; 7, outer wall; 8, draw-in groove; 9, insert port; 10, reinforce groove; 11, connectivity slot cross section.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model locking-type AV terminal embodiment is described further.
A kind of locking-type AV terminal, comprise socket 2 and plug 1, socket 2 comprises inwall 5 and is sheathed on the outer wall 7 outside inwall, insulation between inwall 5 and outer wall 7, on inwall 5, be provided with and reinforce groove 10, reinforce groove 10 and comprise connectivity slot 6 and draw-in groove 8, connectivity slot 6 from insert port 9 to draw-in groove 8 direction settings and be communicated with draw-in groove 8 and insert port 9, connectivity slot 6 is L-type with draw-in groove 8 and is connected, the pin 3 of plug 1 is provided with projection 4, projection 4 is cylindric, and this columned diameter is the same with the width of connectivity slot 6 and draw-in groove 8, when plug 1 inserts socket 2, projection 4 is through after connectivity slot 6, rotating plug 1 makes projection 4 go to the horizontal end of draw-in groove 8, make projection 4 smooth and easy rotary clampings in draw-in groove 8, its protrusions 4 is consistent to the distance of socket 2 bottoms with draw-in groove 8 to the distance of pin bottom, good to reach contact, this connection has realized being fastenedly connected of plug and socket.
Certainly, above-described embodiment is better simply embodiment, practical application can also have more variation, for example, reinforce the various informative of groove 10, it can also be set to S type or C type, here the differentiation of lower connectivity slot 6 and draw-in groove 8 needs further to explain, connectivity slot 64 provides the passage of smooth landing to draw-in groove 8 for projection, and 8 of draw-in grooves are for clamping projection 4, make it be difficult for sliding and cannot axially departing from; Reinforcing groove 10 is 2 quantity Matching even more, still the quantity of projection 4 will and be reinforced groove 10; Projection 4 also can be for bottom surface is foursquare cuboid or hemisphere or other multiedge cylinder, and its key point is in projection 4 through after being communicated with 6 grooves, can smooth and easy rotary clamping to draw-in groove 8, can be not stuck.
