Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector with an improved locking structure. Background Art

[0002] With the widespread application of connectors in many industries, people have put forward higher and higher requirements on the safety, electrical performance and operational convenience of connectors.

[0003] In order to ensure that the connector has lower resistance, better electrical connection stability and a higher level of waterproof performance requirements, it is usually necessary to apply a larger installation force to ensure the assembly between the connector plug and the socket.

[0004] In order to meet the requirement that the connector needs a large installation force to achieve the assembly of the plug and the socket, it is usually necessary to install a power-assisting mechanism on the connector and set a locking structure to lock the power-assisting mechanism. In this way, when the power-assisting mechanism needs to be used for power assistance, the power-assisting mechanism is unlocked by operating the locking structure to meet the activity requirements of the power-assisting mechanism during power assistance, so as to provide auxiliary force (for example, auxiliary thrust) for the user's operation; when the power-assisting mechanism is not needed, the power-assisting mechanism is locked by operating the locking structure to ensure that the power-assisting mechanism will not move at will.

[0005] However, current connectors with power-assist mechanisms have shortcomings: the locking structure used to lock the power-assist mechanism is not only complex in structure, but also cumbersome to operate, and cannot meet the user's needs for easily locking or unlocking the power-assist mechanism, thus reducing the user's operating efficiency of the connector power-assist mechanism.

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] This embodiment provides a connector with an improved locking structure. Figures 1 to 4 As shown, the connector with the improved locking structure of this embodiment includes a connector housing 1, an assist mechanism 2 and a locking structure. The assist mechanism 2 can be movably arranged on the connector housing 1. The locking structure includes a locking member 3 and a locking tongue 4. The locking member 3 cooperates with the connector housing 1 and the assist mechanism 2 respectively to generate a reciprocating rotational movement when the locking member 3 is subjected to an external driving force; the locking tongue 4 is in transmission cooperation with the locking member 3. The locking tongue 4 is configured to cooperate with the connector housing 1 with the rotational movement of the locking member 3 to put the assist mechanism 2 in a locked state or an unlocked state. In this embodiment, the locking member 3 here generates the said rotational movement in a preset plane. The connector housing 1 has a first matching structure 11 that matches the locking member 3. The plane where the first matching structure 11 is located is parallel to the preset plane and is located on the same side of the connector housing 1.

[0038] When the assist mechanism needs to be locked, a pulling force is applied to the locking member to cause the locking member to rotate within a preset plane, and then the locking tongue cooperates with the connector housing as the locking member rotates, thereby putting the assist mechanism in a locked state or an unlocked state.

[0039] Specifically, in this embodiment, see Figures 2 to 4As shown, the power assist mechanism 2 has a second matching structure 21 that matches with the locking member 3; wherein the locking member 3 matches with the first matching structure 11 and the second matching structure 21 respectively, so as to generate the aforementioned rotational movement when subjected to an external driving force. For example, the first matching structure 11 here is a protrusion, the locking member 3 has a locking buckle 31 configured to generate elastic movement after being touched by the protrusion, and the second matching structure 21 has a locking buckle hole 210 for the locking buckle 31 of the locking member 3 to be inserted into and for the locking buckle touched by the protrusion to be moved out. By providing the first matching structure and the second matching structure that match with the locking member respectively, the locking buckle of the locking member can be inserted into the locking buckle hole of the second matching structure when it is not touched by the first matching structure, so that the locking member cannot generate the aforementioned rotational movement. Once the locking buckle of the locking member is touched by the first matching structure, the locking buckle will be moved out of the locking buckle hole of the second matching structure (i.e., the first matching structure set as the protrusion is pushed out), and the locking buckle is no longer restricted by the buckle of the locking buckle hole, and the locking member is in a state of free rotation without being buckled. In this way, as long as a pulling force is applied to the locking member, the locking member will produce the above-mentioned rotational movement, and then the locking tongue will cooperate with the connector housing with the rotational movement of the locking member, so that the power assist mechanism is in a locked state or an unlocked state. That is, see Figure 1 As shown, when the locking member rotates and moves in a clockwise direction, the locking tongue cooperates with the connector housing as the locking member rotates and moves, thereby placing the assist mechanism in a locked state; when the locking member rotates and moves in a counterclockwise direction, the locking tongue cooperates with the connector housing as the locking member rotates and moves, thereby placing the assist mechanism in an unlocked state.

[0040] As a way to realize that the lock tongue cooperates with the connector housing to lock or unlock the power-assist mechanism, in this embodiment, a locking platform 12 is provided on the connector housing 1 to cooperate with the lock tongue 4 to be inserted and removed. For example, the locking platform 12 here is formed with a hole-shaped structure 120 that cooperates with the lock tongue to be inserted and removed.

[0041] According to actual needs, the locking member 3 here has an operating handle 32, and the locking tongue 4 is formed on the locking member 3. In this way, when the operating hand applies a pulling force, the locking member can generate the above-mentioned rotational movement.

[0042] In order to facilitate the above-mentioned rotational movement of the locking member on the connector housing, in this embodiment, see Figure 2As shown, the second matching structure 21 has a mounting cavity 211 for the locking member 3 to rotate therein. In this embodiment, a rotating shaft 21a is formed on the second matching structure 21 and in the mounting cavity 211, and the locking member 3 is formed with a rotating shaft hole 30 for the rotating shaft 21a to be inserted into to rotate with the locking member 3. In this way, when the locking member is in a free rotation state capable of rotating, the locking member can rotate with the rotating shaft hole and the rotating shaft, thereby ensuring that the locking member can rotate in the mounting cavity of the second matching structure.

[0043] In order to limit the rotational movement stroke of the locking member, in this embodiment, a stroke limiting structure 212 for limiting the rotational movement stroke of the locking member 3 is provided on the second matching structure 21 of the power-assisting mechanism 2, and the stroke limiting structure 212 at least cooperates with the locking member 3 to be snapped into the locking buckle hole 210. In other words, by providing the stroke limiting structure here, not only the rotational movement stroke of the locking member is limited, but also the locking tongue on the locking member is ensured to be snapped into the locking hanging platform of the connector housing when or before the stroke of the locking member is limited by the stroke limiting structure, so as to lock the power-assisting mechanism.

[0044] In order to enhance the locking effect of the locking member on the power-assisting mechanism, in this embodiment, see Figure 3 As shown, the locking member 3 is also provided with an elastic protrusion 33 configured to elastically contact and cooperate with the second matching structure 21 to prevent the locking member from performing reverse rotational movement. Two elastic protrusions 33 can be symmetrically provided on the locking member 3 as needed.

[0045] As a setting mode of the power assist mechanism on the connector housing, in this embodiment, the power assist mechanism 2 has a rotating arm 22, and the rotating arm 22 is set on the connector housing 1 by a pivot connection mode.

[0046] The following combination Figures 1 to 12 , the working process of the locking assist mechanism of the locking structure of the connector in this embodiment is explained:

[0047] When the power-assisting mechanism needs to be locked, a pulling force is applied to the operating handle of the locking member, so that the locking member rotates clockwise in the installation cavity of the power-assisting mechanism until the locking tongue on the locking member is engaged with the locking platform on the connector housing, thereby locking the power-assisting mechanism by using the mutually matching locking tongue and locking platform to prevent the power-assisting mechanism from rotating. Since the locking member is also provided with an elastic protrusion, the elastic protrusion in the current state elastically contacts and cooperates with the second matching structure to prevent the locking member from rotating in the reverse direction, thereby further preventing the power-assisting mechanism from moving in the reverse direction. Among them, Figures 7 to 9 This is a schematic diagram when the locking part has not started to rotate clockwise. Figures 10-12 This is a schematic diagram of the locking member after it rotates clockwise.

[0048] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
