Description

Technical Field

[0001] The utility model relates to an electric connector, and in particular to an electric connector with a fool-proof function. Background Art

[0002] In order to realize the electrical connection between different electronic devices, various forms of electrical connectors have been introduced. Electrical connectors can be divided into line-end connectors and board-end connectors according to the location of the installation. The line-end connector is located at one end of the cable and is used to adapt and couple with the board-end connector, while the board-end connector is installed on the circuit board. With the continuous advancement and innovation of the technology of various electronic products, the performance of new electronic products has been greatly improved, and the types of electrical signals have become more diverse and require more bandwidth.

[0003] Data and power can only be transmitted when the plug (line end) connector and the socket (board end) connector are mated in the correct direction. If the plug connector and the socket connector are plugged in at the wrong angle (for example, the plug connector is flipped 180 degrees and plugged in reverse), not only will the transmission function fail, but the terminals may also be damaged. Therefore, the design of an electrical connector with a foolproof structure is an important issue for those skilled in the art. Utility Model Content

[0004] According to some embodiments of the utility model, an electrical connector includes an insulating body, a plurality of conductive terminals and a shell. The insulating body has a slot, and the slot extends along a first direction. The conductive terminal is located in the slot of the insulating body. The shell is sleeved on the insulating body. The upper portion of the shell has a break and an anti-fool structure located in the break. The break extends from a side of the upper portion away from the slot toward the slot. The anti-fool structure includes a horizontal portion and an abutting portion adjacent to the horizontal portion. The width of the anti-fool structure along the first direction is less than or equal to two-thirds of the length of the shell along the first direction, and the angle between the horizontal portion and the abutting portion of the anti-fool structure is in the range of 90 degrees to 180 degrees.

[0005] In some embodiments, the fool-proof structure is higher than the top surface of the upper portion of the housing.

[0006] In some embodiments, the top surface of the fool-proof structure is flush with the top surface of the upper portion of the housing.

[0007] In some embodiments, the thickness of the foolproof structure is the same as the thickness of the upper portion of the housing.

[0008] In some embodiments, the upper portion of the housing is a stepped structure.

[0009] In some embodiments, the step structure includes a first top surface, a second top surface, and an inclined surface. The horizontal portion of the foolproof structure extends from the first top surface to a second direction, and the second direction is perpendicular to the first direction. The second top surface is lower than the first top surface. The inclined surface is adjacent to the first top surface and the second top surface.

[0010] In some embodiments, the breach extends from the first top surface to the second top surface via the inclined surface.

[0011] In some embodiments, the abutment portion is an end of the fool-proof structure away from the first top surface.

[0012] In some embodiments, the fool-proof structure is suspended above the breach.

[0013] In some embodiments, the electrical connector further includes a circuit board, and the insulating body and the housing are located on the circuit board.

[0014] In the above-mentioned embodiment of the utility model, since the upper part of the housing of the electrical connector has an anti-fool structure located in the gap, and the anti-fool structure includes a horizontal portion and an abutting portion, when the electrical connector is docked with another connector, the anti-fool structure can ensure the correct connection direction to transmit data and power, and avoid reverse insertion of the electrical connector, which affects the service life of the conductive terminal due to incorrect compression. In addition, the stop design of the anti-fool structure with a width less than or equal to two-thirds of the length of the housing and the stop design of the angle between the horizontal portion and the abutting portion of the anti-fool structure in the range of 90 degrees to 180 degrees can effectively improve the anti-fool ability of the electrical connector.

[0022] Figure 1 A three-dimensional view of an electrical connector 100 according to an embodiment of the present invention is shown. Figure 2 Draw Figure 1 A partial enlarged view of the electrical connector 100 is shown. Figure 1 and Figure 2 The electrical connector 100 includes an insulating body 110, a plurality of conductive terminals 120 and a shell 130. The insulating body 110 has a slot 111, and the slot 111 extends along a first direction D1. The conductive terminal 120 is located in the slot 111 of the insulating body 110. The shell 130 is sleeved on the insulating body 110, that is, the shell 130 surrounds the insulating body 110. The upper portion 134 of the shell 130 has a break O and an anti-fool structure 131. The anti-fool structure 131 is located in the break O. The break O extends from a side of the upper portion 134 away from the slot 111 (that is, a side of the upper portion 134 close to the circuit board 140) toward the slot 111. The anti-fool structure 131 includes a horizontal portion 132 and an abutting portion 133 adjacent to the horizontal portion 132. In addition, the width W of the fool-proof structure 131 along the first direction D1 is less than or equal to two-thirds of the length L of the housing 130 along the first direction D1, and the angle θ between the horizontal portion 132 and the abutment portion 133 of the fool-proof structure 131 is in the range of 90 degrees to 180 degrees.

[0023] In some embodiments, the insulating body 110 may be made of plastic and electrically insulated from the conductive terminal 120. The housing 130 may be made of metal (e.g., an iron shell) to enhance the structural strength of the electrical connector 100. The electrical connector 100 may be a board-end connector configured to couple with a terminal connector. The electrical connector 100 includes a circuit board 140, and the insulating body 110 and the housing 130 are located on the circuit board 140.

[0024] Specifically, since the upper portion 134 of the housing 130 of the electrical connector 100 has an anti-fool structure 131 located in the breach O, and the anti-fool structure 131 includes a horizontal portion 132 and an abutting portion 133, when the electrical connector 100 is docked with another connector (such as a wire end connector), the anti-fool structure 131 can ensure that the connection direction is correct for data and power transmission. In this way, the electrical connector 100 can be prevented from being reversely inserted, which would affect the service life of the conductive terminal 120 due to incorrect compression. In addition, the stop design of the width W of the anti-fool structure 131 being less than or equal to two-thirds of the length L of the housing 130 and the stop design of the angle between the horizontal portion 132 and the abutting portion 133 of the anti-fool structure 131 being in the range of 90 degrees to 180 degrees can effectively enhance the anti-fool capability of the electrical connector 100.

[0025] It should be understood that the connection relationship, materials and functions of the components described above will not be repeated, and will be described first. In the following description, other technical features of the electrical connector 100 will be described.

[0026] Figure 3 Draw Figure 1 A perspective view of the housing 130 of the electrical connector 100 viewed from another direction. Figure 1 and Figure 3 In some embodiments, the housing 130 may be an integrally formed metal shell, which may be manufactured by stamping. During the manufacturing process, a hole O may be formed in the metal plate, and then the metal plate may be bent into a shape suitable for use in the following embodiments. Figure 1 In addition, the metal plate in the opening O can be bent to form a foolproof structure 131 having a horizontal portion 132 and an abutting portion 133, so that the foolproof structure 131 is suspended above the opening O. In other words, the foolproof structure 131 overlaps the opening O in the vertical direction, and the position of the foolproof structure 131 corresponds to the position of the opening O.

[0027] In addition, the upper portion 134 of the housing 130 may be a stepped structure 135. The stepped structure 135 includes a first top surface 136, a second top surface 137 and an inclined surface 138. The second top surface 137 is lower than the first top surface 136, and the opposite sides of the inclined surface 138 are adjacent to the first top surface 136 and the second top surface 137 respectively. In some embodiments, the first top surface 136 and the second top surface 137 of the stepped structure 135 may be horizontal planes. The horizontal portion 132 of the fool-proof structure 131 extends from the first top surface 136 of the stepped structure 135 in the second direction D2, wherein the second direction D2 is perpendicular to the first direction D1. The breach O extends from the first top surface 136 to the second top surface 137 via the inclined surface 138. The abutment portion 133 of the fool-proof structure 131 is an end of the fool-proof structure 131 away from the first top surface 136, that is, an end close to the second top surface 137.

[0028] Figure 4 Draw Figure 1 1 is a side view of the electrical connector 100. As shown in the figure, since the housing 130 is an integrally formed metal shell and is manufactured by stamping a metal plate, the thickness of the fool-proofing structure 131 is the same as the thickness of any part of the housing 130 (such as the step structure 135). In some embodiments, the fool-proofing structure 131 is not lower than any surface of the upper portion 134 of the housing 130. For example, the fool-proofing structure 131 may be higher than the second top surface 137 of the upper portion 134 of the housing 130 (i.e., the step structure 135), and the top surface of the fool-proofing structure 131 may be flush with the first top surface 136 of the upper portion 134 of the housing 130. Such a stop design can effectively enhance the fool-proofing capability of the electrical connector 100 when docking with another electrical connector.

[0029] The foregoing summarizes the features of several embodiments so that those skilled in the art can better understand the aspects of the present invention. Those skilled in the art should understand that they can easily use the present invention as a basis for designing or modifying other processes and structures to achieve the same purpose and / or achieve the same advantages as the embodiments described herein. Those skilled in the art should also recognize that such equivalent constructions do not depart from the spirit and scope of the present invention, and that they can make various changes, substitutions and modifications here without departing from the spirit and scope of the present invention.
