Description

Technical Field

[0001] The present disclosure relates to the technical field of electrical connection devices, and in particular to an anti-oblique insertion electrical connection device. Background Art

[0002] With the rapid development of science and technology, connectors play a core role in data transmission and energy transfer, and are widely used in various fields such as mobile phones, computers, and servers.

[0003] Prior art, such as patent CN206401629U, proposes an anti-oblique insertion connector, which includes a plug and a socket that are plugged into each other, a plug insulator is provided in the plug, a pin is provided in the plug insulator, and a socket insulator is provided in the socket, and the socket insulator is provided with a socket that cooperates with the pin. A main positioning block and two auxiliary positioning blocks with a width smaller than the main positioning block are provided at the head of the plug, and a main positioning groove and an auxiliary positioning groove that cooperate with the main positioning block and the auxiliary positioning block are provided at the socket. When the plug is inserted into the socket, it must be aligned before it can be inserted, which effectively prevents the user from inserting the plug obliquely and causing damage to the pin.

[0041] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0042] like Figures 1 to 9 As shown, an anti-slant plug electrical connection device 10 of an embodiment includes a plug 100 and a socket 200. The plug 100 includes a plug-to-plug end 110, and the socket 200 includes a socket-to-plug end 210 and a socket terminal 220. The socket-to-plug end 210 is formed with a connecting plug opening 211 and a connecting slot 212. The plug-to-plug end 110 is connected to the connecting slot 212 through the connecting opening 211. The plug-to-plug end 110 is located in the connecting slot 212 and is connected to the socket-to-plug end 212. 0, the direction in which the plug-to-plug end 110 is inserted into the plug-in slot 212 through the plug-in opening 211 is the plug-in direction Z, and the end face of the socket-to-plug end 210 formed with the plug-in opening 211 is the plug-in end face 300; the width direction parallel to the socket-to-plug end 210 is the first preset direction X, and the length direction parallel to the socket-to-plug end 210 is the second preset direction Y, and the plug-in direction Z, the first preset direction X and the second preset direction Y are perpendicular to each other; the socket terminal The portion 220 is protruding from the bottom of the plug-in slot 212, and the distance from the end of the socket terminal 220 located in the plug-in slot 212 to the plug-in end surface 300 is the avoidance dimension L1; the length of the plug opening 211 in the first preset direction X is the first preset dimension L2, and the avoidance dimension L1 is greater than 0.5 times the first preset dimension L2, so that when the plug-in terminal 110 is inserted into the plug-in slot 212 through the plug opening 211 along the first mis-oblique insertion angle A1 in the first preset direction X, the deepest dimension of the portion of the plug-in terminal 110 extending into the plug-in slot 212 is 0.5 times the first preset dimension L2, so that the deepest dimension of the portion of the plug-in terminal 110 extending into the plug-in slot 212 is less than the avoidance dimension L1, thereby effectively preventing the plug-in terminal 110 from touching the socket terminal 220 when the plug-in terminal 110 is inserted into the plug-in slot 212 through the plug opening 211 along the first mis-oblique insertion angle A1 in the first preset direction X.

[0043] like Figures 1 to 9As shown, further, a guide and limit flange 111 is formed on the outer peripheral wall of the plug-to-plug end 110 in the second preset direction Y, and the guide and limit flange 111 extends to the end face of the plug-to-plug end 110. The side of the plug-to-plug end 110 adjacent to the guide and limit flange 111 in parallel to the first preset direction X is a reference side 400. The distance between the guide and limit flange 111 and the reference side 400 in the second preset direction Y is a second preset dimension L3, and the avoidance dimension L1 is greater than the second preset dimension L3, so that when the plug-to-plug end 110 is inserted into the plug groove 212 along the second mis-oblique insertion angle A2 through the plug opening 211 in the second preset direction Y, the guide and limit flange 1 11 will provide limiting support for the plug-to-plug end 110, so that the deepest dimension of the portion of the plug-to-plug end 110 extending into the plug-in slot 212 is equal to the second preset dimension L3, and the deepest dimension of the portion of the plug-to-plug end 110 extending into the plug-in slot 212 is less than the avoidance dimension L1, thereby effectively preventing the plug-to-plug end 110 from touching the socket terminal 220 when the plug-to-plug end 110 is inserted into the plug-in slot 212 along the second mis-inclination angle A2 through the plug opening 211 in the second preset direction Y, greatly reducing the possibility of damage or even destruction of the socket terminal 220, thereby greatly reducing the maintenance cost of the above-mentioned anti-inclination electrical connection device 10.

[0044] In this embodiment, when the plug-to-plug end 110 is inserted into the plug slot 212 along the first mis-oblique insertion angle A1 through the plug opening 211 in the first preset direction X, the plug-to-plug end 110 is respectively abutted against the top of the two side walls of the plug slot 212 parallel to the second preset direction Y, that is, the plug-to-plug end 110 is abutted against the end surface of the socket-to-plug end 210, so that on the reference side surface 400, the portion of the plug-to-plug end 110 extending into the plug slot 212 along the first mis-oblique insertion angle A1 is It can be approximately regarded as a right triangle, so that the deepest dimension of the plug-to-plug end 110 extending into the insertion slot 212 along the first mis-insertion angle A1 is 0.5 times the first preset dimension L2, and the avoidance dimension L1 is greater than 0.5 times the first preset dimension L2, thereby avoiding the plug-to-plug end 110 and the socket terminal 220 from touching when the plug-to-plug end 110 is inserted into the insertion slot 212 along the first mis-insertion angle A1 through the insertion opening 211 in the first preset direction X.

[0045] When the plug-to-plug end 110 is inserted into the plug-in slot 212 along the second misaligned insertion angle A2 through the plug-in opening 211 in the second preset direction Y, the guide and limit flanges 111 respectively abut against the tops of the two side walls of the plug-in slot 212 parallel to the second preset direction Y, that is, the guide and limit flanges 111 can abut against the end surface of the socket-to-plug end 210 to support the plug-to-plug end 110, and on the reference plane formed by the plug-in direction Z and the second preset direction Y, the plug-to-plug end 110 is inserted into the plug-in slot 212 along the second misaligned insertion angle A2. The portion of the plug-in slot 212 that extends into the plug-in slot 212 at the oblique insertion angle A2 can be approximately regarded as a right triangle, so that the dimension of the plug-in end 110 extending into the plug-in slot 212 along the second mis-oblique insertion angle A2 is the second preset dimension L3, and the avoidance dimension L1 is greater than the second preset dimension L3, thereby avoiding the plug-in end 110 and the socket terminal 220 from touching each other when the plug-in end 110 is inserted into the plug-in slot 212 along the second mis-oblique insertion angle A2 in the second preset direction Y through the plug-in opening 211.

[0046] In this embodiment, the plug-to-insert end 110 and the socket-to-insert end 210 are both approximately considered as a rectangular parallelepiped.

[0047] In the above-mentioned anti-oblique insertion electrical connection device 10, since the socket terminal 220 is partially protruding from the bottom of the plug slot 212, the distance between the end of the socket terminal 220 located in the plug slot 212 and the plug end surface 300 is the avoidance dimension L1; the length of the plug opening 211 in the first preset direction X is the first preset dimension L2, and the avoidance dimension L1 is greater than 0.5 times the first preset dimension L2, so that when the plug-in end 110 of the plug is inserted into the plug slot 212 along the first mis-oblique insertion angle A1 through the plug opening 211 in the first preset direction X, the plug-in end 110 extends into the plug slot 21 2 is 0.5 times the first preset dimension L2, so that the deepest dimension of the portion of the plug-to-plug end 110 extending into the plug-in slot 212 is smaller than the avoidance dimension L1, thereby effectively preventing the plug-to-plug end 110 from touching the socket terminal 220 when the plug-to-plug end 110 is inserted into the plug-in slot 212 along the first mis-inclined insertion angle A1 through the plug-in opening 211 in the first preset direction X; at the same time, the outer peripheral wall of the plug-to-plug end 110 is formed with a guide and limit flange 111 in the second preset direction Y, and the guide and limit flange 111 extends to the plug-to-plug end 110. The end face of the plug-to-plug end 110, the side of the plug-to-plug end 110 adjacent to the guide limiting flange 111 in parallel to the first preset direction X is the reference side face 400, the distance between the guide limiting flange 111 and the reference side face 400 in the second preset direction Y is the second preset dimension L3, and the avoidance dimension L1 is greater than the second preset dimension L3, so that when the plug-to-plug end 110 is inserted into the plug groove 212 along the second mis-inclined insertion angle A2 through the plug opening 211 in the second preset direction Y, the guide limiting flange 111 will limit and support the plug-to-plug end 110, so that the plug-to-plug end 110 The deepest dimension of the portion extending into the plug-in slot 212 is equal to the second preset dimension L3, and the deepest dimension of the portion of the plug-to-plug end 110 extending into the plug-in slot 212 is smaller than the avoidance dimension L1, thereby effectively preventing the plug-to-plug end 110 from touching the socket terminal 220 when the plug-to-plug end 110 is inserted into the plug-in slot 212 along the second mis-insertion angle A2 through the plug opening 211 in the second preset direction Y, thereby greatly reducing the possibility of damage or even destruction of the socket terminal 220, thereby greatly reducing the maintenance cost of the above-mentioned anti-slant insertion electrical connection device 10.

[0048] like Figures 2 to 4As shown, in this embodiment, the plug 100 also includes an elastic conductive component 130 and a plastic head base 140. The plug-to-plug end 110 is formed with a mounting groove 112. The plastic head base 140 is installed and fixed in the mounting groove 112. The plastic head base 140 is formed with a mounting through hole 141. The conductive end of the elastic conductive component 130 is arranged in the mounting through hole 141. The conductive end of the elastic conductive component 130 is used to be electrically connected to the socket terminal 220 when the plug-to-plug end 110 and the socket-to-plug end 210 are plugged together, so that the plastic head base 140 can insulate and protect the conductive end of the elastic conductive component 130.

[0049] like Figures 2 to 4 As shown, in this embodiment, the elastic conductive component 130 includes a pin contact 131, a pin base 132 and a cable 133. The pin base 132 forms a limiting hole (not shown in the figure), the pin contact 131 is inserted into the limiting hole, and the first end of the pin contact 131 is electrically connected to the core wire of the cable 133. The second end of the pin contact 131 is arranged in the mounting through hole 141. The pin base 132 is used to fix the cable 133 and the pin contact 131. The pin base 132 is installed and fixed inside the plug body 120 so that the first end of the pin contact 131 can be fixed in the mounting through hole 141.

[0050] like Figures 2 to 4 As shown, in this embodiment, the number of mounting through holes 141 and elastic conductive components 130 are both multiple, and the mounting through holes 141 are evenly distributed on the plastic head base 140. Each mounting through hole 141 is arranged in a one-to-one correspondence with the second end of the pin contact 131 of each elastic conductive component 130 to improve the transmission efficiency of the anti-slant insertion electrical connection device 10.

[0051] like Figures 1 to 5As shown, it can be understood that when multiple cables 133 are fixed on the plug body 120, the multiple cables 133 will be entangled with each other, which may not only cause electromagnetic interference (EMI) or radio frequency interference (RFI), thereby affecting the signal transmission quality of the cables 133, but also the cables 133 may be subjected to excessive bending or squeezing during the winding process, causing the insulation layer to wear, break or the internal conductor to be damaged, thereby greatly reducing the safety of the anti-slant insertion electrical connection device 10 and increasing the maintenance cost. To solve the above problem, in the present embodiment, the plug 100 further includes a cable cover 150, which is installed and fixed on the side of the plug body 120 away from the plug end 110, and the cable cover 150 is formed with a cable hole, through which multiple cables 133 are passed, so that the cable cover 150 can arrange the cables 133 neatly, thereby avoiding electromagnetic interference and insulation layer wear and breakage caused by the entanglement of multiple cables 133 in the above-mentioned anti-slant plug-in electrical connection device 10, which not only greatly improves the signal transmission quality of the cable 133, but also greatly improves the use safety of the above-mentioned anti-slant plug-in electrical connection device 10, and at the same time can also reduce the maintenance cost of the above-mentioned anti-slant plug-in electrical connection device 10.

[0052] like Figures 1 to 5 As shown, it can be understood that the elastic conductive component 130 is only fixed to the plug 100 by the pin base 132, which makes the elastic conductive component 130 easy to fall off from the plug 100. To solve the above problem, in this embodiment, the inner walls of the plug body 120 on both sides parallel to the second preset direction Y are formed with glue injection grooves (not shown in the figure) to facilitate the injection of epoxy glue into the inside of the plug body 120, so that the elastic conductive component 130 and the cable cover 150 can be firmly fixed to the plug body 120 through the epoxy glue, so that the overall compactness of the plug 100 is improved, and the phenomenon of the elastic conductive component 130 falling off from the plug 100 is effectively avoided; at the same time, the position of each cable 133 can be fixed, so that the cables 133 of the above-mentioned anti-slant plug electrical connection device 10 can be neatly arranged, avoiding the phenomenon of electromagnetic interference and insulation layer wear and breakage caused by the entanglement of multiple cables 133, and further reducing the maintenance cost of the above-mentioned anti-slant plug electrical connection device 10.

[0053] like Figures 1 to 8As shown, in this embodiment, the distance between the inner walls of the two sides of the plug slot 212 parallel to the second preset direction Y in the first preset direction X is a first preset dimension L2, so that when the plug-to-plug end 110 is inserted into the plug slot 212 along the first misaligned insertion angle A1 through the plug opening 211 in the first preset direction X, the plug-to-plug end 110 is respectively abutted against the top of the two side walls of the plug slot 212 parallel to the second preset direction Y, that is, the plug-to-plug end 110 is abutted against the end surface of the socket-to-plug end 210, so that the plug-to-plug end The deepest dimension of 110 inserted into the plug slot 212 along the first mis-oblique insertion angle A1 through the plug opening 211 in the first preset direction X is smaller than the first preset dimension L2. Since the avoidance dimension L1 is larger than the first preset dimension L2, the plug-to-plug end 110 is prevented from touching the socket terminal 220 when the plug-to-plug end 110 is inserted into the plug slot 212 along the second mis-oblique insertion angle A2 through the plug opening 211 in the second preset direction Y, thereby greatly reducing the maintenance cost of the above-mentioned anti-oblique insertion electrical connection device 10.

When the plug-to-plug end 110 is inserted into the plug-in slot 212 through the plug opening 211 along the second misalignment angle A2 in the direction opposite to the second preset direction Y, the second guide limit flange 1112 respectively abuts against the top ends of the two side walls of the plug-in slot 212 parallel to the second preset direction Y, that is, the second guide limit flange 1112 can abut against the end face of the socket-to-plug end 210 to support the plug-to-plug end 110.

The elastic retaining ring 180 is sleeved and interference-fitted into the annular clamping groove 161, so that the elastic retaining ring 180 is clamped and fixed on the fastener 160, so that when the plug and the socket are in the plugged state, the fastener 160 can be effectively prevented from coming out of the plug body 120, causing the plug 100 and the socket 200 to separate, thereby further improving the use stability of the above-mentioned anti-oblique plug-in electrical connection device 10.

[0061] like Figure 5 As shown, the plug also includes an annular gasket, which is sleeved on the fastener and located on a side of the plug body away from the plug end, so that the plug can be more securely fixed to the socket.

[0063] like Figures 1 to 7 As shown, in this embodiment, the socket 200 also includes a circuit board 260, and a positioning column 231 is protruding from the side of the socket body 230 away from the socket plug end 210. The circuit board 260 is also formed with a third positioning hole 261 and a connecting hole 262. The positioning hole and the positioning column 231 are arranged opposite to each other. The socket terminal 220 passes through the socket body 230 and is fixedly connected to the socket body 230. The first end of the socket terminal 220 is located in the plug slot 212, and the second end of the socket terminal 220 is arranged opposite to the connecting hole 262, so that the circuit board 260 can be installed at a preset position of the socket body 230 through the mutual cooperation of the positioning column 231 and the positioning hole, so that the second end of the socket terminal 220 can be passed through the connecting hole 262 and electrically connected to the circuit board 260, thereby avoiding the phenomenon of installation misalignment.

[0064] like Figures 1 to 9 As shown, in the present embodiment, the value range of the first mis-insertion angle A1 is 0° to 90°, and the above-mentioned anti-slant insertion electrical connection device 10 can effectively prevent the plug-to-plug end 110 from touching the socket terminal 220 when the plug-to-plug end 110 is inserted into the plug-in slot 212 along the first mis-insertion angle A1 through the plug-in opening 211 in the first preset direction X, thereby greatly reducing the possibility of damage or even damage to the socket terminal 220, thereby greatly reducing the maintenance cost of the above-mentioned anti-slant insertion electrical connection device 10; the value range of the second mis-insertion angle A2 is 0° to 90°, and the above-mentioned anti-slant insertion electrical connection device 10 can effectively prevent the plug-to-plug end 110 from touching the socket terminal 220 when the plug-to-plug end 110 is inserted into the plug-in slot 212 along the second mis-insertion angle A2 through the plug-in opening 211 in the second preset direction Y, thereby further reducing the possibility of damage or even damage to the socket terminal 220, thereby further reducing the maintenance cost of the above-mentioned anti-slant insertion electrical connection device 10.

[0065] like Fig.12 As shown, in this embodiment, the plugging method of the plug 100 and the socket 200 includes:

[0066] S101, aligning the plug-to-plug end 110 to be plugged with the socket-to-plug end 210 to be plugged, so that the plug-to-plug end 110 to be plugged can be plugged into the socket-to-plug end 210 to be plugged, avoiding the phenomenon of oblique insertion.

[0067] S103 , extending the plug-to-plug end 110 to be plugged into the plug-in slot 212 along the plug-in direction Z, so that the plug-to-plug end 110 can abut against the socket terminal 220 .

[0068] S105, the end surface of the plug-to-plug end 110 to be plugged in is brought into contact with the bottom wall of the plugging slot 212, and the plug-to-plug end 110 and the socket-to-plug end 210 are plugged in to ensure that the anti-slant plugging electrical connection device 10 can maintain normal operation.

[0069] like Figure 10 to Figure 11 As shown, it can be understood that due to the large friction force that the socket-to-plug end 210 and the plug-to-plug end 110 are subjected to when separating, it is difficult to completely vertically pull the plug-to-plug end 110 and the socket-to-plug end 210 apart. To solve the above problem, in one embodiment, when the plug-to-plug end 110 is plugged into the socket-to-plug end 210, there are preset spacings between the two side reference side surfaces 400 of the plug-to-plug end 110 and the two side inner walls of the plug-in slot 212 in the second preset direction Y; when the plug-to-plug end 110 is pulled out of the socket-to-plug end 210, the angle between the end surface of the plug-to-plug end 110 and the bottom wall of the plug-in slot 212 in the second preset direction Y is a pull-out swing angle B, so that the above-mentioned anti-oblique plugging electrical connection device 10 can first pull up one end of the plug-to-plug end 110 located on the first reference side surface 400 relative to the inner wall of the plug-in slot 212, and then pull up one end of the second reference side surface 400 of the plug-to-plug end 110 relative to the inner wall of the plug-in slot 212, so as to reduce the friction between the socket-to-plug end 210 and the plug-to-plug end 110, so that the socket-to-plug end 210 can be easily pulled out of the plug-to-plug end 212.

[0070] like Figure 10 to Figure 11As shown, it can be understood that when the plug-to-plug end 110 and the socket-to-plug end 210 are pulled apart by the above-mentioned anti-slant plug electrical connection device 10, a pull-out deflection angle B will be generated between the end face of the plug-to-plug end 110 and the bottom wall of the plug slot 212 in the second preset direction Y. If the pull-out deflection angle B is too large, the plug-to-plug end 110 will crush the socket terminal 220, thereby greatly increasing the maintenance cost of the above-mentioned anti-slant plug electrical connection device 10. To solve the above-mentioned problem, in one embodiment, the pull-out deflection angle B is in the range of 0.6° to 2.3°, so that when the plug-to-plug end 110 and the socket-to-plug end 210 are pulled apart, the wear or even damage of the socket terminal 220 caused by the pull-out deflection angle B between the end face of the plug-to-plug end 110 and the bottom wall of the plug slot 212 in the second preset direction Y is avoided, thereby greatly reducing the maintenance cost of the above-mentioned anti-slant plug electrical connection device 10.
