(23) FIGS. 6 and 7 respectively show perspective views of an electrical connector assembly in an unlocked and locked state according to another embodiment of the present utility model. For the sake of clarity, the first electrical connectors 5 and the second electrical connectors 7 are not shown in FIGS. 6 and 7. Unlike the embodiments shown in FIGS. 3 and 4, in the electrical connector assembly shown in FIGS. 6 and 7, the second interlocking member may include a toggle structure 16 constructed on a side wall of the cavity 18. As shown more explicitly in FIG. 9, the toggle structure 16 includes a support plate 22 and a fulcrum 23, wherein the support plate can elastically rotate about the fulcrum. Specifically, when the second end portion of the support plate 22 is pressed (represented by the arrow 24), the first end portion of the support plate 22 may be raised (represented by the arrow 25); and when the second end portion of the support plate 22 is released, the first end portion of the support plate 22 may spring back to its initial position. The fulcrum 23 may be, for example, a support member formed in the cavity 18 of the housing 6 in a manner such as threaded connection, welding, or integral molding with the cavity 18.

(24) In some embodiments, as shown in FIGS. 6 and 7, the protrusion 11 is constructed on the second end portion of the connecting piece 9, while the hole 14 is constructed on the first end portion of the support plate 22 of the toggle structure 16. The second end portion of the connecting piece 9 can be inserted into the cavity 18 of the housing 6 from the position shown in FIG. 6, so that the protrusion 11 extends into the hole 14 (see FIG. 7). Under such a circumstance, the first electrical connectors 5 and the second electrical connectors 7 can be engaged with each other and the first module 1 and the second module 2 are locked. In order to unlock the first module 1 and the second module 2, the first end portion of the support plate and the hole 14 provided therein may be raised by pressing the second end portion of the support plate 22, so that the protrusion portion 11 can be disengaged from the hole 14. When the protrusion 11 is completely disengaged from the hole 14, the first module 1 and the second module 2 are unlocked, Under such a circumstance, the second end portion of the connecting piece 9 can be pulled out from the cavity 18, and the first electrical connectors 5 and the second electrical connectors 7 can be separated from each other (see FIG. 6). In order to facilitate the pressing operation, a button 17 may be provided on the second end portion of the support plate of the toggle structure 16.

(25) In this embodiment, as shown in FIG. 8, the protrusion 11 may be constructed to be a wedge-shaped protrusion which does not have to be constructed to be elastically extensible as shown in FIGS. 3 and 4. Correspondingly, the hole 14 may be constructed to be a rectangular hole (see FIGS. 6 and 7).

(26) In other embodiments, the hole 14 may be provided in the second end portion of the connecting piece 9, and the protrusion 11 may be provided on the first end portion of the support plate 22 of the toggle structure 16. For example, the protrusion 11 may be provided on the side of the first end portion of the support plate 22 that faces the cavity 18. In such embodiment, the first module 1 and the second module 2 may also be locked and unlocked by pressing the second end portion of the support plate 22 or pressing the button 17.

(27) Compared with the prior art, advantages of the electrical connector assembly according to the above-described specific embodiments of the present utility model may include the following aspects: since a rocker arm is not used, a tool is not needed to operate the locking device, so that it is convenient for use by the user; the locking device may be highly stable, so that the first module 1 and the second module 2 can be safely and reliably locked; and the electrical connector assembly has a simple structure and a small volume, and thus saves the material and reduces the burden on the product provider.

(28) Although the exemplary embodiments of the present disclosure have been described above, a person skilled in the art should understand that, he or she can make multiple changes and modifications to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure.
