Abstract
The utility model discloses a plug terminal, comprising a terminal main body, a cervical part slot and a tail end. A plane surface is milled on the cervical part slot, and the plane surface is provided with a hole which can be a through hole or a not penetrative hole. The existence of the plane surface of a terminal slot makes a cross section arranged at the position of the terminal slot become a non-circular section. Consequently, the turning moment is increased, and the twisting resistance of the terminal is increased, simultaneously, the hole on the plane surface is injected and filled with plastic cement, and the twisting resistance of the terminal is even more increased. So the adoption of this structure is capable of ensuring that the plug can not loosening after used for a long time, and the service life of the plug is prolonged.
Description
Technical field:
The utility model relates to technical field of electronic products, refers in particular to a kind of plug terminal.
Background technology:
People often can use plug in daily life, also are very frequent to the plug of plug.In order to strengthen the fastness of plug and plug terminal, prolong the useful life of plug, people have found out a lot of schemes, and Fig. 1 is the disclosed a kind of plug terminal of patent document that the patent No. is ZL98200944.5.This terminal is based on a metal round rod, and is provided with groove 4 in the tail end of terminal, is provided with the table top 41 stepped with shaft at the side of groove 4, is suppressed with several asperity 411 on the table top 41.This patent promptly is to strengthen the tension and the twisting resistance intensity of terminal by the asperity 411 of suppressing on the table top, thereby makes the close-coupled of terminal and plug insulation division.Its weak point is the length restriction owing to terminal itself, and set table top 41 is not wide, and the effect of the asperity 411 on the table top is restricted, and promptly the fastness of the terminal of this structure and plug insulation division is not enough; Simultaneously, on terminal, offer table top and also increased manufacture craft.
Summary of the invention:
The purpose of this utility model is to provide a kind of plug terminal that a kind of technology is simple, fastness is strong at the deficiencies in the prior art.
The utility model adopts following technical scheme: this terminal comprises terminal bodies, neck groove, tail end, is milled with the plane on the neck groove, offers a hole in the plane.
The utility model adopts very simple structure just to reach the effect that increases terminal and plug insulation division fastness, and manufacture craft is simple.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is disclosed terminal schematic diagram;
Fig. 2 is the schematic diagram of terminal in the utility model;
Fig. 3 is the cutaway view that terminal combines with the plug insulation division in the utility model.
Embodiment:
See accompanying drawing 2, the utility model comprises: terminal bodies 1, neck groove 2, tail end 3, and wherein terminal bodies 1 is used for contacting with the electric installation of socket, and tail end 3 is used for being connected with lead.Be milled with plane 21 on the terminal neck groove 2, offer a hole 211 on this plane 21, this hole 211 can be through hole, perhaps the hole for not running through.
See accompanying drawing 3, terminal is fixed on the plug insulation division 5, to form a complete plug.Combination between terminal and the insulation division 5 adopts the injection moulding formula, promptly when profiled insulation portion 5, terminal is fixed in the mould, makes the plastic material that forms insulation division 5 fill neck groove 2 places, and insulation division 5 and terminal are fixed, and is combined as a whole.Because the existence of terminal groove 2 midplanes 21, make that the cross section of terminal groove 2 positions is a noncircular cross section, so increased terminal twisting resistance intensity (torque increase), hole 211 is filled by plastic cement when injection moulding simultaneously, more increased the twisting resistance intensity of terminal, guarantee that loosening situation can not appear in plug yet after long-time the use, increased the useful life of plug.
Certainly, the embodiment of the above, be the preferred embodiments of the utility model only, be not to limit the utility model practical range, so all do variation or modification according to the described structure of the utility model claim, feature and principle all should be included in the utility model claim.
Claims (1)
1, a kind of plug terminal comprises: terminal bodies (1), neck groove (2), tail end (3) is characterized in that: be milled with plane (21) on the neck groove (2), offer a hole (211) on plane (21).
