Referring to fig. 8 and 16, the wire end connector 2 further includes an elastic blocking ring 23 surrounding the wire end connector 2. When the board end connector 1 is engaged with the wire end connector 2, the elastic blocking ring 23 is tightly matched with the extension tube body 12 of the board end connector 1, and at this time, the elastic blocking ring 23 fills the inner space of the board end connector 1 and the wire end connector 2 which are sleeved with each other, so that the board end connector 1 can tightly engage with the wire end connector 2. In the present embodiment, the elastic blocking ring 23 may be a silicone member, which is used as a sealing member in the connector, so that the connector assembly 100 has the effect of preventing dust, water and other impurities from entering.

Further describing the operating member 3, the operating member 3 is pivotally arranged on the line end connector 2 and is switchable between a locked position and an unlocked position. As shown in fig. 6 and 7, the operating member 3 has two pivoting portions 31, two first extending arms 32 and two second extending arms 33, the pivoting portions 31 are disposed at the pivoting regions 21121 of the side openings 2112, the first extending arms 32 and the second extending arms 33 are disposed at the actuating regions 21122 of the side openings 2112, and the first extending arms 32 and the second extending arms 33 together define a receiving space C.

In addition, the operating member 3 further comprises two side bars 34, a cross bar 35 and two positioning protruding points 36. The pivot portion 31, the first extension arm 32, and the second extension arm 33 are formed on the side lever 34. The cross bar 35 is connected between the two side bars 34 and has a second hook portion 351. The positioning protruding points 36 are formed on the inner side surfaces of the side bars 34, and when the operating member 3 is in the unlocking position, the positioning protruding points 36 are engaged with the first positioning grooves 2114, and at this time, the first hook portions 2113 of the housing 211 and the second hook portions 351 of the cross bar 35 do not interfere with each other. When the operating member 3 is located at the locking position, the positioning protruding point 36 is engaged with the second positioning groove 2115, and at this time, the first hook portion 2113 of the housing 211 and the second hook portion 351 of the cross bar 35 are engaged with each other, so that the board end connector 1 and the wire end connector 2 are tightly engaged. The positioning convex points 36 are engaged with the first positioning grooves 2114 or the second positioning grooves 2115, so that a user can intuitively feel the positioning hand feeling.

The operational relationship of the connector assembly 100 is described in detail below. As shown in fig. 9 to 15, when the board-end connector 1 and the wire-end connector 2 are in an initial state and the operating member 3 is in the unlocked position, the positioning protrusion 36 is engaged with the first positioning groove 2114, and the second extension arm 33 is away from the inner guiding groove 2111, so as to allow the protrusion 121 to enter the accommodating space C along the inner guiding groove 2111 (see fig. 10 and 13). When the board end connector 1 and the wire end connector 2 are switched from the initial state to the engagement state, after the protrusion 121 contacts the first extension arm 32, the protrusion 121 pushes the first extension arm 32 to rotate the operating member 3 (see fig. 11 and 14), so that the user can apply a force on the cross bar 35 to assist the abutting engagement of the board end connector 1 and the wire end connector 2 and the synchronous rotation of the operating member 3. After the protrusion 121 enters the accommodating space C through the inner guiding groove 2111, the protrusion 121 moves along with the first extending arm 32 and the second extending arm 33 in the actuating region 21122, at this time, the protrusion 121 can move from the lowest position to the highest position of the actuating region 21122, and the positioning protrusion 36 is switched from the first positioning groove 2114 and engaged with the second positioning groove 2115, so that the operating member 3 rotates from the unlocking position to the locking position about the pivot portion 31 (refer to fig. 12 and 15). In other words, when the board end connector 1 and the wire end connector 2 are switched from the initial state to the engaged state, the wire end connector 2 and the operating member 3 cannot continue to operate if the second extension arm 33 first interferes against the bump 121. Therefore, the second extension arm 33 has a limiting and stopping function, and also has an anti-misoperation effect.

Similarly, when the board end connector 1 and the wire end connector 2 are to be released from the engaged state, the first hook portion 2113 and the second hook portion 351 are separated from each other, then the operating member 3 is gradually rotated from the locking position to the unlocking position by the force, at this time, the protrusion 121 moves along with the first extension arm 32 and the second extension arm 33 in the accommodating space C, then the second extension arm 33 is gradually moved away from the inner guide groove 2111 (i.e. the second extension arm 33 does not overlap with the inner guide groove 2111 in the vertical direction of the drawing) along with the rotation of the operating member 3, so that the protrusion 121 is separated from the accommodating space C and enters the inner guide groove 2111, and finally the board end connector 1 and the wire end connector 2 can be separated.

In summary, the connector assembly of the present utility model includes a board connector, a wire end connector and an operation member, wherein the board connector is capable of being tightly connected to a high-current connector assembly by combining the operation member with the bump of the board connector through the side opening shape, the first and the second extension arms, and the combination of the operation member. Therefore, the effects of saving manufacturing cost and increasing the stability of the connector can be achieved.

The above-described embodiments are only for illustrating the embodiments of the present utility model, and are not intended to limit the scope of the present utility model. Any modifications or equivalent arrangements which may be readily apparent to those skilled in the art are intended to be included within the scope of the present utility model, which is to be protected by the following claims.
