The present application claims priority from and the benefit of Chinese Utility Model Application No. 202020014063.3, filed Jan. 3, 2020, the disclosure of which is hereby incorporated herein in its entirety.
The present utility model relates to an electrical connector assembly.
Electrical connector assemblies are widely used in the field of electrical or electronic products. In some electrical connector assemblies, for example in an electrical connector assembly known from US 20190312394 A1, as shown in
However, in such electrical connector assembly, it is very laborious to release the rocker arm 21. Normally, a screwdriver is needed to unlock the first module 31 and the second module 32, which is inconvenient for the user. In addition, since each post 30 is fixed in a recess 20 of the rocker arm 21, in some cases, the post 30 might accidentally slide out of the recess 20 due to deformation of the rocker arm 21 in a direction along the post 30, which results in the first module 31 and the second module 32 of the electrical connector assembly are unlocked unexpectedly.
One object of the present disclosure is to provide an electrical connector assembly capable of overcoming at least one drawback in the prior art. The electrical connector comprises: a first module including a mounting plate and a plurality of first electrical connectors, wherein the plurality of first electrical connectors are mounted on the mounting plate in a predetermined layout; a second module including a housing and a plurality of second electrical connectors mated with the plurality of first electrical connectors, wherein the plurality of second electrical connectors are mounted in the housing in the predetermined layout; and a locking device including at least one first interlocking member disposed on the first module and at least one second interlocking member disposed on the second module. One of the first interlocking member and the second interlocking member is provided with a protrusion, and the other of the first interlocking member and the second interlocking member is provided with a hole for receiving the protrusion. One of the protrusion and the hole is elastically actuatable to enable it to move between a first position in which the protrusion extends into the hole, such that the first electrical connector and the second electrical connector are engaged with each other and the first module and the second module are locked; and a second position in which the protrusion is disengaged from the hole, such that the first module and the second module are unlocked and the first electrical connector and the second electrical connector are separable from each other.

In some embodiments, the connecting piece includes a transverse hole, wherein the pin is disposed in the transverse hole of the connecting piece, and an elastic element is provided in the transverse hole, such that the pin is capable of performing an elastically extensible movement.
In some embodiments, an end portion of the pin that is capable of projecting out of the transverse hole is constructed to be a rounded portion, and the rounded portion is capable of projecting beyond the side wall of the cavity through the hole for receiving the protrusion when the first module and the second module are locked.
In some embodiments, the pin may be constructed to be a cylindrical pin.
In some embodiments, the hole for receiving the protrusion is constructed to be a circular hole.
In some embodiments, the first locking member may include a connecting piece, wherein a first end portion of the connecting piece is fixed on a mourning plate, and one of the protrusion and the hole is provided on/in a second end portion of the connecting piece; and the second locking member may include a cavity provided in the housing, and a toggle structure is provided on a side wall of the cavity, wherein the toggle structure includes a support plate and a fulcrum, and the support plate is elastically rotatable about the fulcrum, wherein the other of the protrusion and the hole is constructed on a first end portion of the support plate.
In some embodiments, a button may be provided on a second end portion of the support plate.
In some embodiments, the protrusion may be constructed to be a wedge-shaped protrusion.
In some embodiments, the hole may be constructed to be a rectangular hole.
In some embodiments, the locking device may include two first interlocking members and two second interlocking members.
In some embodiments, at least one friction button may be provided on an outer wall of the housing.
In some embodiments, the first end portion of the connecting piece may be fixed on the mounting plate in a threaded connection manner.
In some embodiments, the housing may be an injection-molded member.
In some embodiments, the mounting plate may be a mounting plate made of brass.
In some embodiments, the connecting piece may be a connection rod made of brass.
In some embodiments, the pin may be a pin made of brass or steel.
