DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The embodiment of the present invention provides a connector for connecting a wiring harness of an automobile with an anti-detachment structure, comprising a connecting mechanism 1. For example, Figure 1 , Figure 2 and Figure 3 As shown, a plug-in mechanism 2 is provided on the top of the connecting mechanism 1; an anti-dropping mechanism 3 is sleeved on the outer wall of the plug-in mechanism 2; and a heat dissipation mechanism 4 is movably penetrated at one side edge of the top of the connecting mechanism 1.

[0041] When connecting the automobile wiring harness, several groups of automobile wiring harnesses are connected to the connecting mechanism 1, and the plug-in mechanism 2 is connected to the male connector as a female connector. The anti-disconnection mechanism 3 can limit the male connector to avoid disconnection with the plug-in mechanism 2, and the heat dissipation mechanism 4 is inserted into the connecting mechanism 1 to perform heat dissipation.

[0042] For example, Figure 4 and Figure 5 As shown, the connection mechanism 1 includes a bottom plate 101; a first shell 102 is provided on the top of the bottom plate 101; a connection cavity 103 is provided in the first shell 102; a plurality of wiring holes 106 are evenly spaced on the inner wall of one side of the bottom of the connection cavity 103; a mounting groove 110 is provided at the bottom of the connection cavity 103; a wiring assembly 108 is provided in the mounting groove 110; two groups of slide grooves 111 are symmetrically provided at the two side edges of the bottom of the mounting groove 110; a group of clamping blocks 112 are slidably connected in each group of the slide grooves 111; each group of the clamping blocks 112 is clamped with the wiring assembly 108; A top cover 104 is provided on the top of the connecting cavity 103; a heat dissipation slot 105 is provided at the edge of one side of the top of the top cover 104; the heat dissipation mechanism 4 is movably inserted into the heat dissipation slot 105; the heat dissipation mechanism 4 is located between the wiring assembly 108 and the wiring hole 106; a plurality of groups of plug pins 109 are evenly spaced at the bottom of the top cover 104; each group of the plug pins 109 is electrically connected to the connector 2; each group of the plug pins 109 is movably inserted into the wiring assembly 108; a plurality of groups of wire clips 107 are evenly spaced at the bottom of the connecting cavity 103; each group of the wire clips 107 is movably inserted into the heat dissipation mechanism 4.

[0043] When connecting the automobile wiring harness, first insert several groups of automobile wiring harnesses into several groups of wiring holes 106 in turn, and then connect the automobile wiring harness to the wiring assembly 108. After the automobile wiring harness is fixed, it is inserted into the corresponding wire clamps 107 in turn, and then the top cover 104 is installed on the top of the first shell 102, so that several groups of pins 109 are inserted into the wiring assembly 108, so that the connector 2 is electrically connected to the automobile wiring harness, and then the heat dissipation mechanism 4 is inserted into the heat dissipation slot 105 and forms a card connection with the bottom of the connecting cavity 103. At the same time, the heat dissipation mechanism 4 can also limit the automobile wiring harness to prevent the automobile wiring harness from being disconnected. By opening the top cover 104, the card connection relationship between the two groups of card blocks 112 and the wiring assembly 108 is released, and then the wiring assembly 108 can be directly taken out, which is not only convenient for wiring work, but also more convenient for maintenance when the connector fails.

[0044] For example, Figure 6 and Figure 7 As shown, the plug-in mechanism 2 includes a second shell 201; a plug-in cavity 205 is provided in the second shell 201; a plurality of groups of elastic power blocks 206 are provided on the bottom inner wall of the plug-in cavity 205; a plurality of groups of elastic power blocks 206 are electrically connected to a plurality of groups of pins 109; a group of limiting rings 207 are provided on the top of each group of elastic power blocks 206; a plug-in slot 202 is provided on one side wall of the second shell 201; a plurality of groups of plug-in holes 203 are provided on the inner wall of the plug-in slot 202 close to the plug-in cavity 205; two groups of baffles 204 are symmetrically provided at the top and bottom edges of a side wall of the second shell 201 close to the plug-in slot 202.

[0045] The elastic current block 206 includes a connecting piece 2061 ; the top of the connecting piece is V-shaped and has two groups of spring pieces 2062 ; the limiting ring 207 is sleeved on the top of the two groups of spring pieces 2062 .

[0046] When the connector is connected, the plug of the male connector is inserted into several groups of socket holes 203. After entering the socket cavity 205, the male plug enters a group of elastic current blocks 206 respectively. The elastic current block 206 is Y-shaped, and the two groups of spring pieces 2062 on the top are fixed by the limit ring 207. When a short circuit occurs in the connector, the elastic current block 206 will generate high temperature, and the high temperature will melt the limit ring 207, so that the two groups of spring pieces 2062 of the elastic current block 206 will pop open to both sides, thereby releasing the electrical connection with the male plug, avoiding fire caused by continuous high temperature, and improving the safety performance of the connector.

[0047] For example, Figure 8 and Fig. 9As shown, the anti-slip mechanism 3 includes a mounting plate 301; the mounting plate 301 is mounted on a side wall of the second shell 201 away from the receiving slot 202; a storage chamber 308 is provided in the mounting plate 301; two groups of telescopic plates 302 are symmetrically and movably penetrated on the inner walls on both sides of the storage chamber 308; each group of the telescopic plates 302 is provided with a group of transmission plates 303 at one end away from the mounting plate 301; two groups of anti-slip plates 304 are symmetrically provided at one end of the two groups of transmission plates 303 close to the receiving slot 202; a plurality of groups of first telescopic slots 305 are symmetrically opened on the opposite side walls of the two groups of anti-slip plates 304; the cross-section of each group of the first telescopic slots 305 is circular, and the two adjacent groups of the first telescopic slots 305 are connected; a group of limiting posts 306 are movably penetrated in each group of the first telescopic slots 305; each group of the limiting posts 306 The cross-sections of the positioning posts 306 are all circular, and the two adjacent groups of the limiting posts 306 are movably fitted together; a group of limiting springs 307 are provided on the inner wall of each group of the first telescopic slots 305 on the side away from the limiting posts 306; each group of the limiting springs 307 are connected to a corresponding group of limiting posts 306; a group of second telescopic slots 310 are respectively opened on the opposite side walls of the two groups of telescopic plates 302; a group of racks 311 are respectively provided on the opposite side walls of the two groups of telescopic plates 302; each group of the racks 311 are movably passed through the corresponding group of second telescopic slots 310; a knob is provided on the side wall of the mounting plate 301 away from the plug-in mechanism 2; one end of the knob extends into the storage cavity 308, and is connected to a transmission gear 309 for transmission; the transmission gear 309 is meshed and connected to the two groups of racks 311.

[0048] After the male connector is inserted into the connector mechanism 2, the knob is turned to drive the transmission gear 309 to rotate. Under the meshing connection relationship between the transmission gear 309 and the two sets of racks 311, the two sets of racks 311 drive the two sets of telescopic plates 302 to move toward the opposite side, so that the two sets of telescopic plates 302 drive the two sets of anti-slip plates 304 to move toward the opposite side through the two sets of transmission plates 303. The several sets of limiting posts 306 on both sides are connected to the socket 202 under the action of the limiting springs 307 to close the socket 202. The corresponding several sets of limiting posts 306 are in contact with the outer wall of the line of the male connector. The several sets of first telescopic grooves 305 connected in sequence can make the two adjacent sets of limiting posts 306 fit together movably to improve the sealing performance without causing directional deviation, so as to prevent dust and moisture in the air from entering the socket 202 in large quantities to affect the electrical connection of the connector. Moreover, since the direction of the male connector is perpendicular to the direction of the several sets of limiting posts 306, the male connector cannot directly detach from the socket 202, thereby improving the connection stability of the connector.

[0049] For example, Fig.10 and Fig.11As shown, the heat dissipation mechanism 4 includes a heat sink 401, on which a plurality of groups of heat-conducting holes 402 are arranged in a rectangular array; a plurality of groups of heat-dissipating holes 404 are arranged at equal intervals above the plurality of groups of heat-conducting holes 402; a group of dust-proof filters 403 are arranged at one end of each group of heat-dissipating holes 404 close to the wiring hole 106; a plurality of groups of wire grooves 405 are arranged at equal intervals at the bottom of the heat sink 401; each group of wire clips 107 is movably inserted into a corresponding group of wire grooves 405; a group of third telescopic grooves 407 are arranged on the top of each group of wire grooves 405; a group of wire pressing blocks 406 are movably inserted into each group of the third telescopic grooves 407; a gas spring 408 is arranged on the top inner wall of the third telescopic groove 407; and the bottom of the gas spring 408 is connected to the top of the wire pressing block 406.

[0050] When connecting the automobile wiring harness, first insert several groups of automobile wiring harnesses into several groups of wiring holes 106 in sequence, then connect the automobile wiring harnesses to the wiring assembly 108, and then insert the automobile wiring harnesses into the corresponding wire clamps 107 in sequence after they are fixed, and then insert the heat dissipation mechanism 4 into the connection cavity 103, so that several groups of automobile wiring harnesses enter one group of wire grooves 405 respectively, and several groups of wire pressing blocks 406 are pressed against several groups of automobile wiring harnesses under the elastic force of the gas spring 408, and cooperate with the wire clamp 107 to form a dislocation clamping, which can prevent the automobile wiring harness from being detached from the connection mechanism 1. A plurality of heat-conducting holes 402 are provided on the heat sink 401, which can increase the contact area between the hot air in the connecting mechanism 1 and the heat sink 401, so that the heat sink 401 can quickly conduct the heat in the connecting mechanism 1 through the plurality of heat-conducting holes 404, thereby improving the heat dissipation effect of the connector, and a group of dust-proof filters 403 are provided in each of the plurality of heat-conducting holes 402 in the connecting cavity 103, which can prevent dust from entering the connecting cavity 103 through the plurality of wiring holes 106 and adhering to the wiring assembly 108 to cause corrosion, thereby improving the service life of the connector.

[0051] For example, Fig.12As shown, the wiring assembly 108 includes a support plate 1081; the support plate 1081 is movably inserted into the installation slot 110; two groups of slots 1082 are symmetrically arranged on the two side walls of the support plate 1081; each group of the slots 1082 is engaged with a corresponding group of blocks 112; a plurality of wiring blocks 1083 are evenly spaced on the top of the support plate 1081; a group of fixing holes 1084 are opened on each group of wiring blocks 1083; a group of fixing screws 1085 are arranged on the top of each group of wiring blocks 1083; one end of each group of fixing screws 1085 extends into the corresponding group of fixing holes 1084; a group of connecting blocks 1086 are arranged on one side wall of each group of wiring blocks 1083; a group of jacks 1087 are opened on the top of each group of connecting blocks 1086; each group of pins 109 are movably inserted into the corresponding group of jacks 1087.

[0052] When connecting the automobile wiring harness, insert the wire end of the automobile wiring harness into the fixing hole 1084, and then rotate the fixing screw 1085 to fix the automobile wiring harness in the fixing hole 1084. The automobile wiring harness is electrically connected to the connector 2 through the connecting block 1086, and the support plate 1081 is fixed by the two sets of card slots 1082 and the two sets of card blocks 112.

[0053] After the male connector is inserted into the connector mechanism 2, the two groups of telescopic plates 302 are controlled to move to the opposite side through the two groups of transmission plates 303 to drive the two groups of anti-slip plates 304. The groups of limiting posts 306 on both sides are connected to the socket 202 to close under the action of the limiting springs 307. The corresponding groups of limiting posts 306 are in contact with the outer wall of the circuit of the male connector. The groups of first telescopic grooves 305 connected in sequence can make the two adjacent groups of limiting posts 306 fit together to improve the sealing performance without causing directional deviation, thereby preventing dust and moisture in the air from entering the connector socket 202 in large quantities to affect the electrical connection of the connector. Moreover, since the direction of the male connector is perpendicular to the direction of the groups of limiting posts 306, the male connector cannot directly detach from the connector socket 202, thereby improving the connection stability of the connector.

[0054] When the connector is working, the several groups of heat-conducting holes 402 opened on the heat sink 401 can increase the contact area between the hot air in the connecting mechanism 1 and the heat sink 401, so that the heat sink 401 can quickly conduct the heat in the connecting mechanism 1 through the several groups of heat-dissipating holes 404, thereby improving the heat dissipation effect of the connector. In addition, the several groups of wire pressing blocks 406 are pressed against the several groups of automobile wiring harnesses under the elastic force of the gas spring 408, and cooperate with the wire clamp 107 to form a staggered clamping, which can prevent the automobile wiring harness from being disconnected from the connecting mechanism 1, thereby improving the use effect of the connector.

[0055] After entering the connector cavity 205, the male plug enters a group of elastic current-conducting blocks 206 respectively. The elastic current-conducting blocks 206 are Y-shaped, and the two groups of spring pieces 2062 on the top are fixed by a limit ring 207. When a short circuit occurs in the connector, the elastic current-conducting block 206 will generate high temperature, and the high temperature will melt the limit ring 207, causing the two groups of spring pieces 2062 of the elastic current-conducting block 206 to spring open to both sides, thereby releasing the electrical connection with the male plug, avoiding fire caused by continuous high temperature, and improving the safety performance of the connector.

[0056] The wiring assembly 108 includes a support plate 1081, which is installed in the installation slot 110. Two groups of card slots 1082 are symmetrically opened on the two side walls of the support plate 1081. The two groups of card blocks 112 are respectively connected to a group of card slots 1082 to fix the wiring assembly 108. When wiring work or maintenance work is required, the connection between the two groups of card blocks 112 and the two groups of card slots 1082 can be released, and the wiring assembly 108 can be taken out of the installation slot 110. The process is simple and quick, which improves the efficiency of wiring and maintenance work.

[0057] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
