Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and particularly relates to an RJ45 connector provided with an anti-fooling structure. Background Art

[0002] The RJ45 connector is commonly known as a crystal head and is generally used to connect an RJ45 crystal plug.

[0003] The existing RJ45 connectors generally do not have an anti-fooling structure, which easily allows an over-sized RJ45 crystal plug to be inserted or an RJ11 crystal plug to be misinserted; or the configured anti-fooling structure is set with an elastic structure. In this case, when the insertion and extraction are relatively fast and the force cannot be withdrawn in time, an over-sized RJ45 crystal plug or an RJ11 crystal plug will still break in forcibly. When an over-sized RJ45 crystal plug or an RJ11 crystal plug is inserted, the pin needles and other parts inside the RJ45 connector are likely to be damaged. Summary of the Utility Model

[0004] The utility model provides an RJ45 connector provided with an anti-fooling structure to solve the above technical problems.

[0005] The solution adopted by the utility model to achieve its technical effect is as follows:

[0006] An RJ45 connector provided with an anti-fooling structure includes a plastic housing, a bracket, and pin needles; an insertion and extraction groove is arranged inside the plastic housing; the bracket is arranged at the bottom of the plastic housing; an anti-fooling step is arranged on the bracket; the pin needles are arranged inside the bracket; one end of the pin needle elastically extends into the insertion and extraction groove in a direction away from the entrance of the insertion and extraction groove, and this end of the pin needle is located above the anti-fooling step; the other end of the pin needle passes through the bottom of the bracket.

[0007] Preferably, an insulating shell is arranged on the outer side of the plastic housing.

[0008] Preferably, positioning grooves are arranged on both side walls of the insertion and extraction groove; elastic clips are arranged on both sides of one end of the insulating shell; each elastic clip is located on one side of the corresponding positioning groove.

[0009] Preferably, an activity groove is vertically arranged on the inner side wall of the insertion and extraction groove; one end of the pin needle is elastically arranged in the activity groove.

[0010] Preferably, the horizontal height of the bottom opening of the activity groove is lower than the horizontal height of the top of the anti-fooling step.

[0011] Preferably, installation card slots are provided on both side walls at the bottom of the plug-in slot; installation blocks are provided on both sides of the bracket; the installation blocks are inserted and fixed in the installation card slots along the opening at one end of the installation card slots.

[0012] Preferably, an interference bump is provided on the top of the installation block; the installation block is tightly clamped with the installation card slot through the interference bump.

[0013] The beneficial effect of the utility model is that a foolproof step is provided. When a RJ45 crystal plug or a RJ11 crystal plug outside the specification range is inserted into the plug-in slot, the pin terminal will touch the foolproof step when pressed down, so that the RJ45 crystal plug or the RJ11 crystal plug cannot be inserted further, thus avoiding the situation of excessive pressing on the pin terminal.
