Description

[0001]
[Industrial application fields]
The present invention relates to a type of receptacle connector, and more particularly to a type of erroneous insertion prevention device and a modular communication network receptacle connector.
[0002]
[Prior art]
Since the width dimension of the RJ-45 plug connector for the communication network and the receptacle connector is required to be larger than the width of the RJ-11 plug connector for the wired telephone network and the receptacle connector, the RJ-11 plug connector is included in the RJ-45 receptacle connector. There is a risk of insertion. Further, when the RJ-11 plug connector is inserted into the RJ-45 receptacle connector, it is conceivable that the conductive terminal in the RJ-45 receptacle connector may be damaged, resulting in electrical breakdown.
[0003]
[Problems to be solved by the invention]
For this purpose, USP 6,022,246 discloses a kind of connector similar to the above, and in order to prevent erroneous attachment of both connectors on the plug connector and receptacle connector that are in contact with each other. Install an insertion prevention structure. However, the structural design as described above cannot be applied to prevent insertion of a small RJ-45 receptacle connector. Also, USP 09 / 536,165 discloses a receptacle connector having a kind of erroneous insertion prevention device, and the erroneous insertion prevention device is provided at the entrance in the receptacle connector housing space, and a connector that contacts the receptacle connector is inserted. By pressing the erroneous insertion prevention device and causing a biased deformation, the abutted connector can be inserted.
[0004]
However, since the erroneous insertion prevention device was provided at the entrance, it provided a sufficient insertion space, and particularly the length in the vertical direction required a sufficient accommodation space for accommodating the erroneous insertion prevention device, Or a space that can rotate it, which is clearly disadvantageous for miniaturized electronic components to be developed, and in the process of frequent insertion of the abutting connector, the erroneous insertion prevention device includes the housing. We think that such a design needs to be further improved because it may fall out of the entrance of the space.
[0005]
The present invention can prevent loss of function due to insertion of a mismatched plug connector by mainly providing a receptacle connector provided with a kind of erroneous insertion prevention device.
[0006]
In addition, according to the present invention, the receptacle connector provided with the erroneous insertion prevention device has a simple structure, improves the strength of the terminal module, has high reliability of the erroneous insertion prevention function, and saves space. Another object is to achieve the effect of reducing the size of electronic parts or reducing the cost.
[0007]
[Means for Solving the Problems]
Based on the main object of the present invention, the receptacle connector of the present invention includes members such as an insulator and a terminal module, and opens an accommodation space for inserting a contact plug connector on the front surface of the insulator, The terminal module is installed on an insulator and includes a base and a plurality of terminals installed on the base by an injection molding method. Each of the terminals includes a contact portion that is obliquely bent at a predetermined angle on the upper surface of the base and extends into the accommodation space, and an end portion that extends rearward to the rear surface of the insulator. A support base protrudes from the upper surface of the base of the terminal module and below the contact portion of the terminal, and a plurality of grooves are formed in the gap between the terminal contact portions adjacent to each pair on the support base. The number of spacers corresponding to the plug connector aligned with the receptacle connector is provided, and is inserted into the concave groove without affecting the elastic contact between the terminals. In addition, the number of spacers of the plug connector that is not aligned cannot correspond to the number of the recessed grooves, and cannot be aligned with the recessed grooves, so that when the plug connector is inserted, the terminal of the receptacle connector is directly pressed to support it. It can be brought into contact with the table to prevent plug connectors that are not aligned from being inserted.
[0008]
【Example】
As shown in FIGS. 1 and 4, an RJ-45 receptacle connector 1 of a kind of erroneous insertion prevention device houses an insulator 10 in which a shield 30 is surrounded on the outside and an RJ-45 plug connector on the front surface. For this purpose, the housing space 11 is opened, the pair of recesses 12 that can each accommodate the light emitting diodes 13 on the top surface 10a, the circular holes 14 that accommodate the guide posts 131 of the light emitting diodes 13, and the openings provided on the surface ( The terminal module 20 is incorporated into the insulator 10 through the opening.
[0009]
As shown in FIGS. 2 and 3, the terminal module 20 is assembled in the insulator 10 and includes a base 22 and a plurality of terminals 21 installed on the base 22 by an injection molding method. Each includes a contact portion 21a that bends obliquely and forms a predetermined angle with the surface on the base 22, and an end portion 21b that extends rearward from the rear surface of the insulator. Further, when the terminal module 20 is assembled to the insulator 10, the terminal contact portion 21 a extends into the accommodation space 11 of the insulator 10.
[0010]
The erroneous insertion prevention device is a support base 40 that protrudes from the upper surface of the base 22 of the terminal module and below the terminal contact portion 21a. In order to prevent the spacer 51 of the RJ-45 plug connector 50 (FIG. 5) from coming into contact with the support base 40, a plurality of concave grooves 41 corresponding to the gaps between the terminal contact portions 21a adjacent to each other are opened on the support base. The front surface of the support base 40 is an inclined surface 42 that forms a predetermined angle on the upper surface of the base 22. Since the distance between the terminal contact portion 21a and the support base 40 is smaller than the yield critical deformation amount of the elastic deformation of the terminal contact portion 21a, the deformation amount when the terminal 21 contacts the support base 40 is not elastically destroyed. It shall be in the range of elastic deformation.
[0011]
As shown in FIGS. 5 and 6, the RJ-45 plug connector 50 aligned with the receptacle connector 1 is provided with a plurality of spacers 51 corresponding to the number of the concave grooves 41, and does not affect the elastic contact between the terminals. Are respectively fitted into the concave grooves 41 of the RJ-45 receptacle connector 1. The number of the spacers 61 of the plug connectors that are not aligned, for example, the RJ-11 plug connector 60, does not correspond to the number of the concave grooves provided in the RJ-45 receptacle connector 50, and therefore cannot be matched with the concave grooves. Moreover, the side wall 62 installed on both sides is formed thicker than the side wall 52 of the RJ-45 plug connector. When it is inserted, the terminal 21 of the receptacle connector 1 is directly pressed and brought into contact with the support base, so that it is possible to prevent insertion of a plug connector that is not aligned.
[0012]
As shown in FIGS. 7 and 8, when the RJ-45 plug connector 50 starts to be inserted into the RJ-45 receptacle connector 1, the horizontal dimension matches the horizontal dimension of the receiving space 11. The side wall 52 on the bottom surface of the RJ-45 plug connector 50 can be immediately inserted from both sides of the bottom surface 10b of the insulator 10, and when the plug connector is inserted into the RJ-45 receptacle connector 1 step by step, the RJ-45 receptacle connector is inserted. Since the number of the spacers 51 corresponding to the groove 41 of the socket is provided in the socket 41, the spacer 51 is inserted into the groove 41 correspondingly without affecting the elastic contact between the terminals.
[0013]
As shown in FIGS. 9 and 10, when an unmatched plug, such as the RJ-11 plug connector 60, is started to be inserted into the RJ-45 receptacle connector 1, the width of the RJ-11 plug connector is larger than the width of the RJ-45 receptacle connector. Since it is small, the RJ-11 plug connector 60 can be inserted into the accommodating space 11 of the insulator 10. Further, when the RJ-11 plug connector 60 is inserted into the RJ-45 receptacle connector 1 by one step, the size of the central spacer 61 corresponds to the size of the intermediate groove of the RJ-45 receptacle connector 1. Even so, the number of spacers on the RJ-11 plug connector does not correspond to the number of grooves, so that the thick side wall 62 is the outermost terminal unit arranged in parallel in the RJ-45 receptacle connector 1. By directly abutting on both terminals, both terminals are forcibly pressed and cause elastic deformation. However, since the distance between the terminal contact portion 21a and the support base is smaller than the yield critical deformation amount of the terminal contact portion elastic deformation, the terminal contact portion 21a has already contacted the support base 40 before yielding. Since the bending deformation becomes impossible, it is prevented that the RJ-11 plug connector which is not aligned is inserted in one step and the terminal is not destroyed.
[0014]
Since the support base 40 is located in a space formed after the terminals are bent, a necessary space can be saved, and a plurality of corresponding contact portions 21a of the terminals adjacent to each other on the support base 40 can be saved. Since the concave groove 41 is opened and the support base 40 protrudes from the base 22 of the terminal module, the structure is simple and the cost can be reduced.
