The terminal plugged in the left end of the pin connector is ejected by the rapid leftward movement of the ejection column, so that the terminal is separated from the pin connector, that is, the input end of the connector is automatically powered off.

[0021] 2. When the ejection column ejects to the left, it will also move the second rack to the left, and the second rack meshes with the gear to rotate counterclockwise, and the gear meshes with the first rack to move right, and the first rack pushes the second heat conduction plate to move right, and the right end of the second heat conduction plate is used to eject the output terminal connected to the tubular connector, that is, the output end of the connector is automatically powered off. When the connector is at high temperature, it can not only be separated from the power terminal at the input end, but also from the power terminal at the output end. The implementation of the output end separation action is determined by the input end action, which ensures that the input terminal is effectively disconnected from the problematic connector, and also ensures that the components where the output terminal is located can also be effectively disconnected from the problematic connector, achieving double protection for the input and output ends.

DETAILED DESCRIPTION

[0031] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0032] In one embodiment, if Figure 1-Figure 8 As shown:

[0033] This embodiment provides an electrical connector and an electrical connector assembly, including a body 1, an integrated seat 2 is fixed inside the body 1, a pin-type connector 3 is provided at the left end of the integrated seat 2, a tube-type connector 4 is provided at the right end of the integrated seat 2, the terminal interface of the input end is connected to the pin-type connector 3, and the terminal interface of the output end is connected to the tube-type connector 4, a connecting hole 5 is opened from the left end of the body 1 to the right, a first power-off assembly 6 is installed in the connecting hole 5, and an assembly groove 7 is opened from the right end of the integrated seat 2 to the left, and a second power-off assembly 8 is installed in the assembly groove 7;

[0034] The first power-off assembly 6 can be ejected to the left to separate the terminal connected to the left end of the body 1 to the left;

[0035] The second power-off assembly 8 can be ejected to the right to separate the terminal connected to the right end of the body 1 to the right;

[0036] A rack assembly 9 is provided between the second power-off assembly 8 and the first power-off assembly 6 . When the first power-off assembly 6 is ejected to the left, the rack assembly 9 drives the second power-off assembly 8 to be ejected to the right.

[0037] As a further preference, the number of the pin-type connectors 3 and the number of the tube-type connectors 4 are the same, and they are connected together at one end located in the integrated seat 2 .

[0038] As a further preferred embodiment, the bottom of the connecting hole 5 is opened close to the right end of the body 1, and the first power-off assembly 6 includes a spring 61 filled in the connecting hole 5, and also includes an ejection column 62 fixed on the left end of the spring 61, the other end of the spring 61 is against the bottom of the connecting hole 5, the left end of the ejection column 62 is flush with the left end of the integrated seat 2, and the right end of the ejection column 62 is used to compress the spring 61 to shorten it in the connecting hole 5;

[0039] A side groove is provided inwardly from the side of the body 1, and a straight groove 10 communicating with the connecting hole 5 is provided at the top of the side groove. The first power-off assembly 6 also includes a limiting rod 63. The first power-off assembly 6 also includes a first heat conduction plate 64 fixed in the side groove, and also includes a weight-loss block 65 downwardly mounted on the first heat conduction plate 64. A rubber sleeve 66 is sleeved on the weight-loss block 65. A penetration hole 67 is provided on the top of the first heat conduction plate 64. The weight-loss block 65 is downwardly mounted in the penetration hole 67 of the first heat conduction plate 64 from the top. The rubber sleeve 66 is provided with an outer protrusion 68, which falls on the top surface of the first heat conduction plate 64, so that the top of the weight-loss block 65 is limited above the top surface of the first heat conduction plate 64. The top of the limiting rod 63 passes through the straight groove 10 into the connecting hole 5 and is connected to the outer wall of the ejection column 62. The bottom end of the limiting rod 63 is exposed in the side groove and limited on the right side surface of the weight-loss block 65.

[0040] As a further preference, the connection holes 5 are symmetrically arranged at four locations, namely, upper, lower, front and rear, and a group of first power-off components 6 is provided in each connection hole 5 . Side grooves corresponding to the first power-off components 6 are provided on the front and rear surfaces of the main body 1 corresponding to the number of the first power-off components 6 .

[0041] A positioning cavity 69 is opened from the right end of the ejection column 62 to the left, and the left end of the spring 61 is inserted into the positioning cavity 69 .

[0042] The second power-off assembly 8 includes a second heat-conducting plate 81 installed in the assembly groove 7 from the right end to the left, and the right end of the second heat-conducting plate 81 is exposed at the right end of the assembly groove 7 and is flush with the right end of the integrated seat 2;

[0043] The rack assembly 9 includes a gear 91 connected in the positioning groove 71, a first rack 92 fixed on the positioning plate 82, and a second rack 93 fixed on the ejection column 62. The first rack 92 is meshed on the bottom side of the gear 91, and the second rack 93 is meshed on the top side of the gear 91.

[0044] like Figures 5 to 8 As shown, the body 1 is divided into two parts, left and right, which are connected by screws for easy assembly. The first heat conduction plate 64 and the second heat conduction plate 81 are both made of copper plates, which have the function of heat dissipation and thermal conductivity, and can release the heat generated by the integrated seat 2 to the outside, and at the same time transfer the heat to the weightless block 65, which transfers the heat to the rubber sleeve 66 at the top. When the heat is too high, the rubber sleeve 66 and the peripheral protrusion 68 at the bottom of the rubber sleeve 66 will be plastically deformed. When the degree of plastic deformation is equal to the weightlessness of the weightless block 65, the weightless block 65 will fall down and no longer limit the limiting rod 63. The spring 61 will eject and eject the input terminal from the pin connector 3 by ejecting to the left using the ejection column 62.

[0045] Working principle and technical effect: The terminal interface at the input end is connected to the pin connector 3, and the terminal interface at the output end is connected to the tube connector 4. No matter which end the heat generated by the electrical appliance is transferred to the main body 1 through the cable, and then transferred to the integrated seat 2 by the main body 1. A part of the higher heat on the integrated seat 2 is transferred to the first heat conduction plate 64 through the grooves on both sides, and the other part is transferred to the second heat conduction plate 81 through the assembly groove 7. Since both plates are made of copper plates, they transfer heat at a high speed. The heat on the second heat conduction plate 81 is released to both sides and then collected on the first heat conduction plate 64. The heat is transferred to the weightless block 65 by the first heat conduction plate 64 in a short time. When the temperature on the weightless block 65 exceeds the melting point of the rubber sleeve 66, the rubber sleeve 66 will be plastically deformed, and at the same time, the peripheral protrusion 68 protruding on the outer periphery of the rubber sleeve 66 will also be plastically deformed. The weightless block 65 is solid metal. When the plasticity of the peripheral protrusion 68 is less than the dead weight of the weightless block 65, the weightless block 65 moves along the through hole 67. As the pin 62 falls downward, the top of the weightless block 65 no longer restricts the surface of the limiting rod 63, and the ejection column 62 integrated with the limiting rod 63 is no longer restricted. The spring 61 is no longer compressed to the right, and at this time, the spring 61 will quickly release its length and push the ejection column 62 to move left quickly while releasing its length. The ejection column 62 quickly moves left to eject the terminal plugged into the left end of the pin connector 3, so that the terminal is separated from the pin connector 3, that is, the input end of the connector is automatically powered off. There are two groups (i.e., two front and rear positions on the upper side, and two front and rear positions on the lower side), and the weightless blocks 65 in them are all installed on the through holes 67 of the four first heat conduction plates 64 in a manner restricted by rubber sleeves 66. In addition to heat dissipation for the integrated seat 2 in the body 1, these first heat conduction plates 64 also transfer heat to the rubber sleeves 66 when the integrated seat 2 suddenly reaches a high temperature, so that these weightless blocks 65 fall from the through holes 67, causing the four ejection columns 62 to eject the terminals of the input ends under the ejection action.

[0046] like Figure 6 As shown, when the ejection column 62 ejects to the left, it will also move the second rack 93 to the left, and the second rack 93 meshes with the gear 91 to rotate counterclockwise, and the gear 91 meshes with the first rack 92 to move right, and the first rack 92 pushes the second heat conduction plate 81 to move right, and the right end of the second heat conduction plate 81 is used to eject the output terminal connected to the tubular connector 4, that is, the output end of the connector is automatically powered off. It can be seen that when the connector is at high temperature, it can not only be separated from the power terminal of the input end, but also from the power terminal of the output end, and the implementation of the output end separation action is determined by the input end action, which ensures that the input end terminal is effectively disconnected from the problematic electrical connector, and also ensures that the components where the output end terminal is located can also be effectively disconnected from the problematic electrical connector, thus achieving double protection for the input and output ends.

[0047] When the above problem occurs, in order to improve the disconnection efficiency between the output end and the electrical connector, the positioning grooves 71 are symmetrically arranged at two locations, and a set of rack assemblies 9 are respectively arranged in the upper and lower positioning grooves 71. The two sets of rack assemblies 9 transmit motion to the upper and lower ejection columns 62 in the same way.

[0048] The second power-off assembly 8 also includes a positioning plate 82 fixed on the upper and lower ends of the second heat conduction plate 81. The upper and lower ends of the assembly groove 7 are provided with positioning grooves 71, and the positioning plate 82 is flat on the positioning groove 71; the positioning plate 82 is composed of two upper and lower pieces, which are respectively welded to the upper and lower ends of the second heat conduction plate 81. The groove formed by the upper assembly groove 7 and the upper and lower positioning grooves 71 is in the shape of an "I". The second heat conduction plate 81 and the upper and lower positioning plates 82 form an "I"-shaped plate and are assembled in the "I"-shaped groove, which not only increases the heat dissipation area of ​​the second heat conduction plate 81, but also ensures that the second heat conduction plate 81 moves smoothly when it ejects to the right.

[0049] The present invention also provides an electrical connector assembly, comprising the electrical connector as described above.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0051] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention.
