Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a novel connector structure that reduces plugging and unplugging forces in a stepped manner. Background Art

[0002] A connector is a bridge that connects two conductors in a loop to achieve the transmission of electrical signals. Currently, in the market, there are multiple terminals on the same connector, including large-sized terminals, and there is a problem of excessive insertion and extraction force during connector operation.

[0003] The related prior art discloses an automotive electronic connector terminal connection structure, including a plurality of wires, and also including a female terminal, the female terminal being arranged on the wire; a male terminal, the male terminal being arranged on the wire; a connector shell, the connector shell being arranged on the female terminal; a connector shell, the connector shell being arranged on the male terminal; by inserting the male terminal into the female terminal, and clamping the male terminal by a connecting assembly, thereby ensuring that the female terminal and the male terminal are closely fitted, thereby improving the connectivity between the female terminal and the male terminal, and then inserting the connector shell into the connector shell, and using the locking assembly to lock the connector shell on the connector shell. When in use, the connector shell is inserted into the connector shell, and the locking assembly is used to lock the connector shell on the connector shell, so that the female terminal can be inserted into the connector shell more smoothly, thereby facilitating the operator to quickly place the female terminal in the connector shell.

[0004] With regard to the above-mentioned related technologies, when the terminal connector is manufactured by this method, when the female terminal and the male terminal are plugged in and out, since a large number of different types of terminal springs are in contact at the same time, the friction during the plugging and unplugging process is large, which affects the assembly efficiency. Utility Model Content

[0005] In order to reduce the force required for plugging and unplugging a terminal connector and improve assembly efficiency, the present application provides a novel connector structure that reduces the plugging and unplugging force in a step-by-step manner.

[0006] The present application provides a novel connector structure with a stepped insertion and extraction force reduction, which adopts the following technical solution:

[0007] A new connector structure with stepped reduction of plugging and unplugging force comprises a female connector and a male connector, wherein the female connector and the male connector are plugged into each other to achieve connection, a plugging area is provided on the side of the female connector facing the male connector, the plugging area comprises a first plugging surface and a second plugging surface, and the plane where the first plugging surface is located is parallel to the plane where the second plugging surface is located and is not coplanar.

[0008] By adopting the above technical solution, by dividing the plug-in area into a stepped first plug-in surface and a second plug-in surface, different types of terminal spring clips are respectively inserted into the first plug-in surface and the second plug-in surface to form staggered insertions, so that the insertion force peak points of different types of terminal spring clips are not on the same plane, thereby reducing the force required for the connector when plugging and unplugging, which is beneficial to improving assembly efficiency.

[0009] Optionally, a plurality of first plug-in terminals are arranged on the first plug-in surface, and a plurality of second plug-in terminals are arranged on the second plug-in surface, and the distance between the plane where the first plug-in surface is located and the plane where the second plug-in surface is located is consistent with the difference in plug-in depth between the first plug-in terminal and the second plug-in terminal.

[0010] By adopting the above technical solution, the depth of the first plug-in terminal inserted in the first plug-in surface is consistent with the depth of the second plug-in terminal inserted in the second plug-in surface. Without affecting the staggered plug-in, the internal structure of the connector is simplified, and there is no need to set different structures for different types of terminals, which is convenient and quick.

[0011] Optionally, a protective shell is provided on the female connector, and the protective shell covers the connection between the female connector and the male connector.

[0012] By adopting the above technical solution, the protective shell can protect the connection between the female connector and the male connector, reduce the occurrence of connector damage due to collision, reduce the phenomenon of the female connector and the male connector being separated from each other during operation, and improve the stability of the connection between the male connector and the female connector.

[0013] Optionally, a locking rod is provided on the protective shell, one end of the locking rod is connected to the protective shell, and the other end is connected to a locking buckle, and a locking block is provided on the male connector, and the locking block and the locking buckle are engaged with each other.

[0014] By adopting the above technical solution, the locking buckle realizes an elastic connection with the protective shell through the locking rod. When the male connector drives the locking block to be inserted into the female connector, the locking buckle first moves and then resets under the elastic deformation of the locking rod, thereby realizing the locking of the locking block, further improving the connection stability between the male connector and the protective shell, and reducing the phenomenon of mutual separation between the male connector and the female connector.

[0015] Optionally, a first wedge-shaped surface is provided on a side of the locking buckle facing the male connector, and a second wedge-shaped surface is provided on a side of the locking block facing the female connector.

[0016] By adopting the above technical solution, the first wedge surface and the second wedge surface can be arranged to fit and abut against each other and slide against each other, thereby reducing the phenomenon of the locking buckle and the locking blocks being stuck to each other when the male connector is inserted into the female connector.

[0017] Optionally, a flexible seal is provided on a peripheral wall of the female connector, and a side of the flexible seal away from the female connector abuts against the male connector.

[0018] By adopting the above technical solution, the setting of the flexible seal can fill the connection gap between the female connector and the male connector, reduce the entry of external moisture or foreign matter into the connector, improve the connection stability between the male connector and the female connector, and reduce the occurrence of accidents.

[0019] Optionally, a protrusion is provided on a side of the flexible sealing member facing the male connector, and the protrusion is interference fit with the male connector.

[0020] By adopting the above technical solution, the provision of the protrusions further improves the sealing performance of the flexible sealing element.

[0021] Optionally, a mounting hole is provided on the female connector, a TPA board is inserted into the mounting hole, and the TPA board is used to achieve secondary locking of the terminal spring clip.

[0022] By adopting the above technical solution, the TPA board has a simple structure and can lock different types of terminals in the same plane to achieve rapid assembly.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By dividing the plug-in area into a stepped first plug-in surface and a second plug-in surface, different types of terminal springs are inserted into the first plug-in surface and the second plug-in surface respectively, so that the insertion force peak points of different types of terminal springs are not on the same plane, thereby reducing the force required for the connector to be plugged in and out, which is conducive to improving assembly efficiency.

[0025] 2. The protective shell can protect the connection between the female connector and the male connector, reduce the occurrence of connector damage due to collision, reduce the phenomenon of the female connector and the male connector being separated from each other during operation, and improve the stability of the connection between the male connector and the female connector.
