Description of the embodiments
The present application will now be described in detail with reference to the drawings and the specific embodiments thereof, wherein the exemplary embodiments and descriptions of the present application are provided for illustration of the application and are not intended to be limiting.
Examples
Referring to fig. 1-11, there is provided in this embodiment an electrical plug capable of excessive current flow, comprising: the male and female connectors 100, 200 can be nested within one another.
The male connector 100 includes a first housing 101, and a first electrode main conductor male member 102, a second electrode main conductor male member 103, and a first electrode auxiliary conductor male member 104 are disposed in the first housing 101. One of the first electrode and the second electrode is a positive electrode, and the other is a negative electrode.
The first electrode auxiliary conductor male member 104 is electrically connected with the first electrode main conductor male member 102, and is the same electrode, and the impedance of the first electrode auxiliary conductor male member 104 is greater than the impedance of the first electrode main conductor male member 102;
the female connector 200 includes a second housing 201, and a first electrode main conductor female member 202, a second electrode main conductor female member 203, and a first electrode auxiliary conductor female member 204 are provided in the second housing 201.
The first electrode auxiliary conductor parent element 204 is electrically connected to the first electrode main conductor parent element 202 and is the same electrode, and the impedance of the first electrode auxiliary conductor parent element 204 is larger than the impedance of the first electrode main conductor parent element 202.
When the male plug-in 100 is nested with the female plug-in 200:
the first electrode primary conductor male member 102 is nested within the first electrode primary conductor female member 202,
the first electrode secondary conductor male member 104 is nested within the electrode secondary conductor female member,
the second electrode main conductor male part 103 is nested and spliced with the second electrode main conductor female part 203,
thereby realizing the positive and negative pole nested plugging of the male plug-in 100 and the female plug-in 200.
In this embodiment, the end length of the first electrode auxiliary conductor male member 104 is set longer than the first electrode main conductor male member 102, and the end length of the first electrode auxiliary conductor female member 204 is set longer than the first electrode main conductor female member 202, so that when the male connector 100 is nested with the female connector 200, the first electrode auxiliary conductor male member 104 contacts the first electrode auxiliary conductor female member 204 prior to the first electrode auxiliary conductor male member 104 contacting the first electrode main conductor female member 202.
After the first electrode main conductor male member 102 is in contact with the first electrode main conductor female member 202, the first electrode auxiliary conductor male member 104 is connected in parallel with the first electrode auxiliary conductor male member 104, and the first electrode auxiliary conductor female member 204 is connected in parallel with the first electrode auxiliary conductor female member 204, so that the impedance of the first electrode main conductor male member 102 and the first electrode main conductor is close to zero and can be almost ignored, and most of current passes through the first electrode main conductor male member 102 and the first electrode main conductor female member 202 with smaller impedance because the first electrode main conductor male member 102 and the first electrode main conductor are made of conductors with good electric conduction performance.
For the above reasons, we will refer to the main plug conductors as the main conductors when the electrical plug is operating normally, and to the conductors that are mainly active at the moment of plug-in to avoid momentary sparks, but are not active at normal operation as the auxiliary conductors.
As can be seen from the above, in the present embodiment, since the male component 104 and the female component 204 of the first electrode auxiliary conductor with relatively large impedance are respectively disposed in the male component 100 and the female component 200, when the male component 100 and the female component 200 are plugged, the male component 104 of the first electrode auxiliary conductor with relatively large impedance and the female component 204 of the first electrode auxiliary conductor are contacted first to reduce the contact instantaneous current first.
When the first electrode main conductor male member 102 is in contact with the first electrode main conductor female member 202, the first electrode auxiliary conductor male member 104 is connected in parallel with the first electrode auxiliary conductor male member 104, the first electrode auxiliary conductor female member 204 is connected in parallel with the first electrode auxiliary conductor female member 204, and most of the current passes through the first electrode main conductor male member 102 and the first electrode main conductor female member 202 with smaller impedance. Compared with the technical scheme that sparks are avoided by increasing the impedance of the positive and negative main conductors in the prior art, the internal resistance is lower and the loss is smaller when the electric plug-in unit adopting the technology of the embodiment works normally.
As an illustration of the present embodiment, the present inventors found that the application of the technical solution of the present embodiment to the first electrode main conductor male member 102, the first electrode auxiliary conductor male member 104, the first electrode main conductor female member 202, and the first electrode auxiliary conductor female member 204, which are all positive, can more effectively avoid the occurrence of the instant spark during the connection, which is a preferred technical solution of the present embodiment.
Referring to fig. 8 and 9, the outer wall of the first housing 101 and the inner wall of the second housing 201 are respectively provided with a convex rib 105 and a groove 205 which can be mutually matched and nested, and when the male plug 100 is nested and plugged with the female plug 200, the convex rib 105 is embedded and limited in the groove 205.
In the present embodiment, the first housing 101 is provided with the rib 105 and the second housing 201 is provided with the groove 205, but the present application is not limited to this, and the first housing 101 may be provided with the groove 205 and the second housing 201 may be provided with the rib 105.
The grooves 205 and the ribs 105 are used for avoiding reverse connection of the positive electrode and the negative electrode of the electric plug.
As an illustration of the present embodiment, the present embodiment takes the example of the first electrode main conductor male member 102, the second electrode main conductor male member 103, the first electrode main conductor female member 202, and the second electrode main conductor female member 203 which are inserted into each other in the male connector 100 and the female connector 200, but the present application is not limited thereto.
For example, the number of the first electrode main conductor male members 102 is two or more, and the number of the first electrode main conductor female members 202 correspondingly plugged with the first electrode main conductor male members is consistent with the number of the first electrode main conductor male members 102.
Alternatively, the number of the second electrode main conductor male members 103 may be two or more, and the number of the second electrode main conductor female members 203 inserted in a corresponding manner may be identical to the number of the second electrode main conductor male members 103.
Alternatively, the number of the first electrode auxiliary conductor male members 104 may be two or more, and the number of the first electrode auxiliary conductor female members 204 inserted in a corresponding manner is identical to the number of the first electrode auxiliary conductor male members 104.
In this embodiment, the impedance value may be set to a larger impedance value by, but not limited to, connecting the first resistor and the second resistor in series to the first electrode auxiliary conductor male member 104 and the first electrode auxiliary conductor female member 204, respectively.
The first resistor, the second resistor and the corresponding series connection wires can be packaged in the first shell 101 and the second shell 201 as shown in fig. 1-7, and the technical scheme can simplify the structure of the electric plug-in unit. The series connection wires may be led out of the first casing 101 and the second casing 201, and the first resistor and the second resistor may be connected out of the first casing 101 and the second casing 201, as shown in fig. 10 and 11.
As an illustration of this embodiment, in addition to the above-mentioned manner of increasing the impedance of the first electrode auxiliary conductor male member 104 and the first electrode auxiliary conductor female member 204 by means of the external resistor, instead of using the external resistor, the first electrode auxiliary conductor male member 104 and the first electrode auxiliary conductor female member 204 may be made of a metal material with a larger resistivity, and may be set to have a smaller cross section and a longer length to increase the impedance thereof to a predetermined value.
As an illustration of the present embodiment, the present inventors have found that setting the impedance of the first electrode auxiliary conductor male member 104 and the first electrode auxiliary conductor female member 204 to 80 ohms or more can cope with various large currents, avoiding occurrence of sparks.
As an illustration of this embodiment, a connector for external connection is further provided on a housing formed by the first housing and the second housing, and an insulating sheath for protecting the connector is further screwed on the housing near the connector, that is, a screw thread screwed on the insulating sheath is provided on the housing.
As an illustration of the present embodiment, the first electrode main conductor male member 102, the second electrode main conductor male member 103, and the first electrode auxiliary conductor male member 104 are respectively tubular.
As an illustration of this embodiment, the first electrode main conductor female member 202, the second electrode main conductor female member 203, and the first electrode auxiliary conductor female member 204 are respectively tubular with at least one split along the longitudinal direction of the tube, and this arrangement is advantageous for improving the plugging tightness between the male member and the female member and improving the conductivity.
Referring to fig. 8 and 9, in the present embodiment, the first case 101 and the second case are respectively injection-molded with a gel, and all the series wires, resistors, conductors, and the like in the first case 101 and the second case are embedded in the gel.
In summary, in the present embodiment, the first housing 101 and the second housing 201 are molded with glue, the conductors are fixed, and all the conductors, wires, and the like are molded in the housing. The electrode conductor uses a long-short mode to avoid the spark generated by the male plug 100 and the female plug 200 in the process of inserting, and the impedance of the first electrode auxiliary conductor male part 104 and the first electrode auxiliary conductor female part 204 reduces the current when contacting the first electrode auxiliary conductor male part 104 and the first electrode auxiliary conductor female part 204 in the process of inserting.
The foregoing has described in detail the technical solutions provided by the embodiments of the present application, and specific examples have been applied to illustrate the principles and implementations of the embodiments of the present application, where the above description of the embodiments is only suitable for helping to understand the principles of the embodiments of the present application; meanwhile, as for those skilled in the art, according to the embodiments of the present application, there are variations in the specific embodiments and the application scope, and the present description should not be construed as limiting the present application.
