Description

The reinforcement type network interface connector

Technical field

The utility model relates to electric connector field, especially a kind of reinforcement type network interface connector.

Background technology

In order to guarantee the integrated strength character that is installed on RJ-45 module together; Tend to a plurality of RJ-45 modules are installed concentratedly in same reinforcing housing to form the reinforcement type network interface connector; Yet because each the RJ-45 module that is assemblied in the same reinforcing housing can only be through its shielding properties that contacts with each other the integral body that realizes the reinforcement type network interface connector of outside shielding case separately; And in use; Owing to relatively move unavoidably between each RJ-45 module, in a single day separate between the adjacent two RJ-45 modules because of relatively moving, the bulk shielding effect of being played when then the two contacts has not just existed; Therefore; In order to guarantee the shielding properties of reinforcement type network interface connector, present reinforcement type network interface connector all is the reinforcing housings that adopt metal, and adopts the reinforcement type network interface connector of metal shell to have following shortcoming: 1) the metal shell cost is higher; 2) metal shell is generally the machining moulding, and the surface also needs processing such as nickel plating, so life cycle of the product is longer; 3) carrying out the general weatherability of surface-treated metal shell does not have the strong of engineering plastics, and this makes that then the useful life of product is shorter.In sum, the cost height and the performance of the reinforcement type network interface connector of the reinforcing housing of employing metal material are difficult to satisfactory.

Summary of the invention

The purpose of the utility model is to provide a kind of reinforcement type network interface connector, to solve existing reinforcement type network interface connector owing to the high problem of manufacturing cost that adopts metal reinforced housing to cause.

In order to address the above problem; The reinforcement type network interface connector of the utility model adopts following technical scheme: a kind of reinforcement type network interface connector; The reinforcing housing that comprises insulation; Be provided with installing hole between the rear and front end of said reinforcing housing, be provided with two above RJ-45 modules in the said installing hole, said each RJ-45 module has shielding case separately; The shielding case of said each RJ-45 module electrically connects through at least one shield blade, and said shield blade press-fits between the hole wall of said installing hole and each RJ-45 module.

Have on the said shield blade towards the hole wall of said installing hole or towards the protruding tensioner protuberance of said each RJ-45 module.

Described RJ-45 module has at least a pair of; Each end of incoming cables to the RJ-45 module is oppositely arranged and corresponding the electric connection; Said each shield blade all have the barb that turnover forms in its front end or rear end separately; The end face of the corresponding end of said reinforcing housing is provided with the draw-in groove corresponding with the barb of said each shield blade, and the barb of each shield blade all is flush-mounted in the corresponding draw-in groove.

Said barb is provided with the barb protuberance with the corresponding cell wall interference fit of said draw-in groove.

Described RJ-45 module has at least two pairs, and each is to being set up in parallel between the RJ-45 module.

Because the shielding case of each RJ-45 module of said reinforcement type network interface connector electrically connects through at least one shield blade, said shield blade press-fits between the hole wall of said installation and each RJ-45 module; Therefore can the shielding case of said each RJ-45 module be electrically connected and be one; In the bulk shielding that realizes the reinforcement type network interface connector; Guarantee to shield each RJ-45 module through reinforcing housing again under the prerequisite of its shielding properties; Thereby make that reinforcing housing can be processed by relatively inexpensive insulating material such as engineering plastics; Simplify its production technology when increasing its useful life, and then reduced the production cost of reinforcing housing from every side, promptly solved existing reinforcement type network interface connector owing to the high problem of manufacturing cost that adopts metal reinforced housing to cause.

Embodiment

The embodiment 1 of reinforcement type network interface connector shown in Fig. 1-4, has the housing 1 of reinforcing; Reinforcing housing 1 is the square plate housing of engineering plastics material, is provided with installing hole between the front and back end of reinforcing housing 1, one in front and one in back is equipped with two RJ-45 module 2 (commercial article in the installing hole; Will not give unnecessary details), each RJ-45 module 2 has the shielding case 2-1 of metal respectively, and the terminals of two RJ-45 modules 2 are oppositely arranged and corresponding the electric connection; The shielding case 2-1 of two RJ-45 modules electrically connects through a shield blade 3, and specifically, promptly shield blade 3 is erected on simultaneously on the shielding case of two RJ-45 connectors and through the hole wall of reinforcing the installing hole on the housing 1 and compresses; Thereby make shield blade 3 that two RJ-45 modules are not needed to shield through reinforcing housing 1 again; Also make above-mentioned reinforcing housing 1 can adopt relatively inexpensive insulating material such as engineering plastics when having realized the reliable shielding of reinforcement type network interface connector, thereby reduce the material cost of reinforcement type network interface connector, in addition; The reinforcing housing that adopts engineering plastics to process also can adopt means such as injection moulding to process; Realize one-shot forming, than the machine work form that metal mold is reinforced housing, production technology obtains simplifying; Be easy to realize producing in enormous quantities; Thereby reduced the processing cost of reinforcing housing, moreover, also compensated the gap between RJ-45 module 2 and the reinforcing housing 1 between the hole wall that shield blade 3 is located at installing hole and the shielding case of RJ-45 module 2; Thereby make that the cooperation of the two is more reliable, avoided the generation of RJ-45 module 2 problem of play in reinforcing housing 1; In the present embodiment, shield blade 3 is elastic strip and has the tensioner protuberance 3-1 to two RJ-45 modules protrusion, and 3-1 is curved for this tensioner protuberance; Formed by shield blade 3 bending, tensioner protuberance 3-1 can realize better on the one hand and the contact of the shielding case of corresponding RJ-45 module, further hold out against the RJ-45 module on the other hand; Prevent that it is movable in installing hole, the rear end of shield blade 3 has the barb 3-2 that turnover forms, and this barb 3-2 hooks from the rear end face of reinforcing housing 1 and reinforces housing 1; Specifically; Be that said barb takes the shape of the letter U, the rear end face of reinforcing housing 1 is provided with the draw-in groove corresponding with said barb, and each barb embeds in the corresponding draw-in groove; Thereby realized fixing to shield blade 3; The barb of each shield blade embeds on the part of corresponding draw-in groove and is equipped with barb protuberance 3-2.1 in addition, and this barb protuberance 3-2.1 is used to realize the soft interference fit between the cell wall of corresponding barb and draw-in groove, thus further fixed mask sheet.

In other embodiment of reinforcement type network interface connector, the quantity of RJ-45 module can also be more than two described in the embodiment 1 of reinforcement type network interface connector, and the shielding case of each RJ-45 module all electrically connects through shield blade; Tensioner protuberance on the described shield blade also can be protruding to the hole wall of said installing hole; Described barb can also be located at the front end place of shield blade; In addition, that the described RJ-45 module among the embodiment 1 only has is a pair of (the RJ-45 module that two terminals are oppositely arranged constitutes a pair of), and in other embodiments, described RJ-45 module can also be for more than two pairs, and each is to being set up in parallel between the RJ-45 module.
