CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority under 35 U.S.C. § 119 to Chinese Patent Application No. 202010615809.0, filed Jun. 30, 2020, the entire disclosure of which is incorporated herein by reference.
FIELD OF THE INVENTION
The present disclosure relates to a connector housing assembly, and more specifically, to a connector housing assembly having improved electromagnetic shielding.
BACKGROUND
In embodiments of the prior art, an internal space of a housing of a laminated connector is divided into multiple rows and columns of insertion chambers by a plurality of vertical separation walls and a plurality of horizontal partition members. An elastic latch may be formed on each of the top wall and the bottom wall of the horizontal partition member. The elastic latch extends into the corresponding insertion chamber, so as to lock a mating connector inserted into the corresponding insertion chamber.
In the prior art, however, there is typically a gap formed between the side of the partition member and the side wall of the insertion chamber of the housing, which reduces the electromagnetic shielding performance of the connector. In addition, in the prior art, in order not to affect the range of movement of the elastic latch, a slot for avoiding the elastic latch is usually formed on each of the top wall and the bottom wall of the partition members, which further reduces the electromagnetic shielding performance of the connector.
SUMMARY
According to an embodiment of the present disclosure, a connector housing assembly comprises a housing defining an accommodation space having a left side wall and a right side wall arranged opposite each other in a transverse direction of the housing. A partition member is inserted into the accommodation space for dividing the accommodation space into an upper insertion chamber and a lower insertion chamber. A shielding member is installed within the partition member and includes elastic contacts extending from lateral sides of the partition member for pressing on the left and right side walls of the accommodation space.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
According to an embodiment of the present disclosure, a connector housing assembly comprises a housing having at least one accommodation space, each of which has a left side wall and a right side wall opposite to each other in a transverse direction of the housing. At least one partition member is inserted into the at least one accommodation space along a longitudinal direction of the housing, and at least one shielding member is installed within the at least one partition member. Each partition member divides a corresponding accommodation space into an upper insertion chamber and a lower insertion chamber. Each shielding member has elastic contacts exposed from both sides of the partition member, and are pressed on or engaged with the left and right side walls of the accommodation space.
FIG. 1 is an illustrative perspective view of a connector housing assembly according to an exemplary embodiment of the present disclosure. FIG. 2 is an illustrative perspective view of a partition member 30 and a shielding member 40 installed on or within the partition member 30 according to an exemplary embodiment of the present disclosure.

The top wall 41 of the shielding member 40 is continuous, with no opening or slot provided thereon for avoiding or accommodating the upper latch 30a. In this way, the electromagnetic shielding performance of the connector is further improved.
As shown in FIGS. 1-4, in an embodiment, the partition member 30 includes a bottom plate 32, and the shielding member 40 includes a bottom wall 42 facing the bottom plate 32 of the partition member 30. A cantilever type lower latch 30b is formed on the bottom plate 32 of the partition member 30. Likewise, no opening or slot is formed for avoiding the lower latch 30b on the bottom wall 42 of the shielding member 40. In this way, the electromagnetic shielding performance of the connector may be further improved.
As shown in FIGS. 1-4, in an embodiment, the partition member 30 also includes a pair of side plates 33 at the left and right sides thereof, and a front side plate 34 at the front side thereof. An installation chamber 30d having left and right openings is defined among the top plate 31, the bottom plate 32 and the front side plate 34, the shielding member 40 is inserted into the installation chamber 30d, and the elastic contacts 40a, 40b, 40c are exposed from the left and right openings of the installation chamber 30d.

As shown, each elastic contact 40a, 40b, 40c may define a pair of elastic tabs.
As shown in FIGS. 1-4, in an embodiment, the first elastic contact 40a seals a horizontally extending top gap between the top side of the partition member 30 and the side wall of the accommodation space 101. The second elastic contact 40b seals a horizontally extending bottom gap between the bottom side of the partition member 30 and the side wall of the accommodation space 101. The third elastic contact 40c seals a vertically extending front gap between the front side of the partition member 30 and the side wall of the accommodation space 101.
