Abstract
The utility model relates to a novel male plug connector comprising an insulation shell body. Pins are arranged on one end of the insulation shell body in a symmetrical mode. The other end of the insulation shell body extends outwardly to form a boss. A first groove and a second groove matched with a boss of a female plug are arranged in a symmetrical mode on the boss of the connector. The lower portion of the boss extends to form a hand-held portion. The insulation shell body is provided with a groove. Metal sheets connected with the pins are arranged inside the groove in a symmetrical mode. A fuse is embedded between the two metal sheets. The periphery of the insulation shell is also provided with a third groove. A grounding spring is connected to the inside of the third groove in an embedded connection mode. The grounding spring is formed by means of connecting a step portion, an interconnecting portion, and an arc portion into one body. Through the arrangement of the boss on one end of the insulation shell body, and the arrangement of the grooves for the abutted joint with the female plug, the reliability of connection between the novel male plug connector of the utility model and the female plug is substantially improved. Through the arrangement of the grounding spring, a contact area between the novel male plug connector and the female plug connection spring is substantially raised.
Description
Technical field
The utility model relates to electric equipment products, relates in particular to a kind of novel public plug connector.
Background technology
At present, the connected mode of existing public plug and female mostly is by pin directly pegs graft, and both can realize being electrically connected to, but in use there is following shortcoming in this connected mode:
(1) public plug and female easily come off each other after being subject to external force, make blow-by between the two, easily are subject to dust, the impact of the factors such as aqueous vapor, thus produce outage, affect the normal use of electrical equipment.
(2) existing public plug only plays the electrical energy transfer effect between power supply and equipment; when overload occurs in electric equipment; the electric current increase causes the electric equipment heating; if persistent fever; the temperature of device interior rises thereupon; the insulation property of inner lead, electronic component reduce and even insulating barrier melts the generation short circuit, and meeting initiation fire when serious, so in the urgent need to a kind of public plug that possesses the instant cut-off defencive function.
(3) structure of existing public plug, with after female is connected, poor electric conductivity easily occurs, connects inconvenient shortcoming.
The utility model content
The applicant is for above-mentioned existing issue; be studied improvement; a kind of novel public plug connector is provided; have advantages of that waterproof and dustproof is effective; and also possesses the up time power-off protection function; greatly improved the protection of electric equipment and the operational security that has guaranteed the operator, and further improved and being connected between public plug and female reliably reach sealing.
The technical scheme that the utility model adopts is as follows:
A kind of novel public plug connector, comprise insulation shell, an end in described insulation shell is arranged symmetrically with pin, and the other end of the described insulation shell formation boss that stretches out is arranged symmetrically with suitable the first groove and the second groove of boss for female on described boss; Bottom at described boss also extends to form Handheld Division; Also have groove on described insulation shell, be arranged symmetrically with the sheet metal be connected with pin in described groove, chimeric fuse between two metal sheets; Be positioned at described insulation shell periphery the 3rd groove also is set, in described the 3rd groove, rabbet grounding elastic part, described grounding elastic part is connected to form one by end difference, connecting portion and arc sections.
Its further technical scheme is:
Described the first groove is oval arc groove, and the second groove is circular groove;
Described Handheld Division is annular inner concave;
Described pin is cylindrical;
Described boss is circular, and the boss diameter is greater than the diameter of insulation shell;
Described groove is rectangular channel.
The beneficial effects of the utility model are as follows:
(1) by the end at insulation shell, boss is set, and arrange the groove connected for female on boss, greatly improved the connection reliability between the utility model and female, realized that the utility model is connected with the secondary of female, and guaranteed both connection sealing to there is higher water resistance.
(2) have groove on insulation shell, cloth holding fuse in groove, according to the fuse of the different current values of power configuration of electronics, electric equipment, solved electronics, electric equipment and caused damage equipment because of overload or electric leakage, the get an electric shock problem of online accident of personnel, improved fail safe greatly.
(3) by grounding elastic part is set, and the arc sections of grounding elastic part and insulation shell periphery are fitted tightly, greatly improved the contact area that is connected shell fragment with female, both connection electric conductivities are improved, improved both operating efficiencies.
The accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is front view of the present utility model.
The end view that Fig. 3 is Fig. 2.
The structural representation that Fig. 4 is grounding elastic part.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, the utility model comprises insulation shell 1, in an end of insulation shell 1, is arranged symmetrically with pin 101, and pin 101 is cylindrical.The other end of insulation shell 1 stretches out and forms boss 2, and boss 2 is circular, and boss 2 diameters are greater than the diameter of insulation shell 1.Suitable the first groove 201 and the second groove 202, the first grooves 201 of boss that are arranged symmetrically with on described boss 2 for female are oval arc groove, and the second groove 202 is circular groove.Bottom at boss 2 also extends to form Handheld Division 3, and Handheld Division 3 is annular inner concave.Also have groove 105 on described insulation shell 1, groove 105 is rectangular channel, is arranged symmetrically with the sheet metal 106 be connected with pin 101 in groove 105, chimeric fuse 107 between two metal sheets 106; Be positioned at insulation shell 1 periphery the 3rd groove 102 also is set, in the interior interlocking grounding elastic part 108 of the 3rd groove 102, grounding elastic part 108 is connected to form one by end difference 1081, connecting portion 1082 and arc sections 1083.
Concrete installation process of the present utility model is as follows:
By fuse lid (the not shown in the figures meaning out, the size of the size of fuse lid and groove 105 matches) cover, after sealing up groove 105, the end face of boss 2 of the present utility model is corresponding with the end face of female (not shown), make on the female end face corresponding with the utility model the first groove 201 and the suitable boss of the second groove 202, then the utility model and female are connected to each other, the boss of female is inserted in the first groove 201 and the second groove 202, the end face of boss 2 and the end face of female fit tightly, effectively guaranteed that connection between the two reliably reaches sealing.In use, fuse 107 is embedded in two metal sheets 106, solid and reliable.
