Background

Chinese patent publication No. CN 205621959U discloses a shielding case comprising a metal housing and a plurality of elastic modules. The metal shell is provided with a top wall, a bottom wall and two side walls, and a plurality of buckling holes respectively formed on the top wall, the bottom wall and the two side walls. The elastic modules are respectively arranged at the end edges of the openings of the top wall, the bottom wall and the two side walls. Each elastic module is provided with a first elastic sheet unit and a second elastic sheet unit. The tail end of each finger part of the first elastic sheet unit positioned at the inner side of the metal shell is provided with a positioning unit, each positioning unit is provided with a buckling part extending and penetrating through the corresponding buckling hole and two wing parts protruding from two sides of the buckling part respectively, and the two wing parts and the first elastic sheet unit are positioned at two opposite sides of the metal shell and are used for propping against the metal shell to prevent the buckling part from being separated from the buckling hole.

However, the end of the finger of the second dome unit located outside the metal shell is a free end that is not fixed, a potential risk of this existing design is that the tail end of the outer finger may be mishandled, so that the very thin outer finger is easily subjected to external forces to permanently deform, for example, by the operator's glove, cloth hooking, or over-pressing at the front end of the finger. If the tail ends of the fingers are not in contact with the metal shell due to permanent deformation, they are also considered as rejected parts and cannot be shipped to the customer.

Detailed Description

Referring to fig. 1 to 4, an embodiment of a connector assembly 100 of the present utility model is adapted to be disposed in a mounting hole 202 of a bezel 201 (bezel) of a housing 200, and adapted to be plugged into a pluggable module (not shown), wherein the bezel 201 and the housing of the pluggable module are electrically conductive. The connector assembly 100 comprises a guiding shield 1 and at least one conductive pad 2. For simplicity of illustration, the embodiment only shows a partial portion of the guiding shield 1 and one of the conductive pads 2 corresponding to the partial portion of the guiding shield 1 in the drawings, but the embodiment may actually include a plurality of the conductive pads 2.

Referring to fig. 2 to 5, the guide shield 1 is constructed, for example, in a metal plate body, and is made of, for example, a metal sheet by press working and bending. The guide shield 1 extends substantially in a front-rear direction D1 (the arrow direction is forward and the reverse direction is backward), and has a top wall 11 and a bottom wall (not shown) spaced apart in a top-bottom direction D2 (the arrow direction is upward and the reverse direction is downward), and two side walls 12 spaced apart in a left-right direction D3 (the arrow direction is right and the reverse direction is left) and connected between the top wall 11 and the bottom wall. The top wall 11, the bottom wall and the side walls 12 together form a front end bezel 13 at the front end, and the front end bezel 13 is configured to allow the pluggable module to be inserted therein, so that the pluggable module can be mated with a receptacle connector (not shown) in the guide shield 1. The guide shield 1 further has a plurality of buttonholes 14 formed in a row and aligned in the left-right direction D3, a plurality of stopper holes 15 formed in another row and aligned in the left-right direction D3, and an inner concave portion 16 formed on the inner surface by, for example, press molding and located at the rear ends of the plurality of stopper holes 15. Specifically, a plurality of snap holes 14 and a plurality of stopper holes 15 are formed in the top wall 11, and the inner recess 16 is formed in the bottom surface of the top wall 11. The inner concave portion 16 has a long shape extending laterally in the left-right direction D3, and the inner concave portion 16 is formed on the bottom surface of the top wall 11 (the inner surface of the guide shield 1) by press molding, and an outer convex portion 17 corresponding to the inner concave portion 16 is also formed on the top surface of the top wall 11 (the outer surface of the guide shield 1). In addition, each of the fastening holes 14 is located behind each of the limiting holes 15 and the inner recess 16.

Referring to fig. 3, 4, 6 and 7, the conductive pad 2 is assembled to the guide shield 1, and the conductive pad 2 has a front base 21, and an inner spring 22 and an outer spring 23 extending rearward from the front base 21. The front end base 21 is assembled at the front end bezel 13 of the pilot shield 1, that is, at the front end of the top wall 11. The inner spring piece 22 extends rearward along the inner surface of the guide shield case 1 (the bottom surface of the top wall 11), and the outer spring piece 23 extends rearward along the outer surface of the guide shield case 1 (the top surface of the top wall 11). The inner spring piece 22 has a plurality of inner elastic fingers 221 aligned in the left-right direction and corresponding to the plurality of fastening holes 14, respectively, and the outer spring piece 23 has a plurality of outer elastic fingers 231 aligned in the left-right direction and corresponding to the plurality of limiting holes 15, respectively. The inner elastic fingers 221 of the inner elastic sheet 22 are used for contacting with the housing having conductivity of the pluggable module; the outer elastic fingers 231 of the outer spring plate 23 are used to contact the edge of the mounting hole 202 of the conductive shield 201.

The end of each inner elastic finger 221 is provided with a buckling part 222 for movably hooking the corresponding buckling hole 14 provided on the guiding shielding case 1, and two wing parts 223 respectively protruding from two sides of the buckling part 222. After the buckling portion 222 and the two wing portions 223 on each inner elastic finger portion 221 pass through the corresponding buckling hole 14 from the inner side (the bottom surface of the top wall 11) of the guiding shielding case 1, the buckling portion 222 and the two opened wing portions 223 are reversely connected to the outer side (the top surface of the top wall 11) of the guiding shielding case 1, and the overall width of the buckling portion 222 and the two opened wing portions 223 is larger than that of the buckling hole 14, so as to prevent the buckling portion 222 from being separated from the buckling hole 14.

The end of each outer elastic finger 231 is provided with a limiting finger 232 which is movably limited in the corresponding limiting hole 15 provided on the guiding shielding case 1. The limiting finger 232 of each outer elastic finger 231 has at least a first extending section 232a and a second extending section 232b, and the second extending section 232b extends from the end of the first extending section 232a and bends towards the outer direction (upward direction in the drawing) relative to the first extending section 232 a. The width of the stop finger 232 is smaller than the width of the outer elastic finger 231, and the difference in level between the end of the outer elastic finger 231 and the stop finger 232 constitutes two abutment shoulders 233. The limiting finger 232 on each outer elastic finger 231 passes through the corresponding limiting hole 15 from the outer side of the guide shield 1 (the top surface of the top wall 11) and extends backward along the inner surface of the guide shield 1 (the bottom surface of the top wall 11), the limiting finger 232 is inserted into the gap between the inner concave portion 16 and the inner elastic finger 221 through the first extending section 232a and the second extending section 232b that is raised, and the limiting finger 232 is at least partially located in the inner concave portion 16 to avoid or reduce interference between the limiting finger 232 on each outer elastic finger 231 and each inner elastic finger 221. The limiting finger 232 on each of the outer elastic fingers 231 is located between the inner recess 16 and each of the inner elastic fingers 221, so that each of the inner elastic fingers 221 can protect the limiting finger 232 from being pulled by the pluggable module inserted into the guide shield 1. The limiting finger 232 at the end of each outer elastic finger 231 is movably limited in each limiting hole 15 on the guide shield 1, which allows each outer elastic finger 231 to have a space for displacement toward the guide shield 1, so as to prevent the outer elastic fingers 231 from being damaged due to improper operation.

The two abutment shoulders 233 are configured to abut against the outer surface of the guide shield 1 (the top surface of the top wall 11) when the outer elastic finger 231 is displaced toward the outer surface of the guide shield 1 (the top surface of the top wall 11). It is possible to prevent each of the outer elastic fingers 231 from collapsing by being excessively pressed when mounted to the barrier 201, and to provide a sufficient contact normal force (normal force) between the plurality of outer elastic fingers 231 and the barrier 201 to enhance electromagnetic shielding (EMI) performance.

In summary, the fastening portion 222 at the end of each inner elastic finger 221 of the present utility model is movably fastened to each fastening hole 14 of the guiding shield 1; the limiting finger 232 at the end of each outer elastic finger 231 is movably limited in each limiting hole 15 on the guide shield 1, so as to prevent the outer elastic fingers 231 from being damaged due to improper operation. The abutment shoulder 233 is formed on each of the outer elastic fingers 231 to prevent each of the outer elastic fingers 231 from collapsing when mounted on the shield 201, and to provide sufficient contact normal force between the outer elastic fingers 231 and the shield 201 to enhance electromagnetic shielding performance. In addition, the limiting finger 232 on each outer elastic finger 231 is disposed between the inner recess 16 and each inner elastic finger 221 on the inner surface of the guide shield 1, so as to protect the limiting finger 232 from being hooked by the pluggable module inserted into the guide shield 1. And, the limit finger 232 can be at least partially received within the inner recess 16 at the inner surface to avoid or reduce interference of the limit finger 232 on each of the outer resilient fingers 231 with each of the inner resilient fingers 221.

However, the above-mentioned embodiments are merely examples of the present utility model, and the present utility model is not limited to the embodiments, but is intended to cover modifications and equivalent arrangements included within the scope of the appended claims and their equivalents.
