Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of network connectors, and particularly relates to an RJ45 connector. Background Art
[0002] RJ45 is a network interface specification mainly used for data transmission. In a wiring system, RJ45 is a type of information socket connector. RJ45 consists of a plug and a socket. The plug is also called a crystal head, which has eight grooves and eight contacts. The socket generally exists on devices such as network cards, computers, switches, etc. The socket also has eight contacts corresponding to the plug, and through the cooperation with the plug, the transmission of network signals is realized. There are multiple RJ45 socket ports on a switch. Generally, there are dozens or even hundreds of RJ45 socket ports on the switches used in data centers. With the development of information technology, the required data transmission rate is getting higher and higher, and the data volume is getting larger and larger. Consequently, the number of RJ45 socket ports required by the switch is also increasing. Currently, when more ports are needed, the only way is to increase the number of switches or use a frame switch to achieve the goal. Therefore, how to increase as many RJ45 socket ports as possible on the panel with a limited area of a single switch has become a challenge. Summary of the Utility Model
[0003] The purpose of the utility model is: aiming at the deficiencies in the above background art, to provide a new type of RJ45 connector. By distributing eight contacts in two rows of four each on the upper and lower sides of the socket, compared with the traditional RJ45 socket with eight contacts arranged side by side, the area of the port surface is reduced by more than 40%, so as to facilitate the switch to design more network ports.
[0004] To achieve the above purpose, the utility model provides an RJ45 connector, including a socket and a plug;
[0005] The socket includes a socket housing and metal pins. The socket housing is provided with a slot. There are a total of eight metal pins, which are evenly divided into two groups and arranged on opposite sides of the inner wall of the slot. A wire is embedded inside the socket housing, and pins are arranged outside the socket housing. The metal pins are connected to the pins through the wire.
[0006] The contacts on the plug are divided into two rows, and four contacts are arranged in each row. The upper row of contacts is located on the upper surface of the plug housing, and the lower row of contacts is located on the lower surface of the plug housing. A wire is embedded inside the plug housing. The first end of the wire is connected to the contact, and the second end of the wire extends out from the wire hole of the plug housing.
[0007] Further, both the socket housing and the plug housing are made of plastic.
[0008] Further, the metal pins are arranged in an inverted triangular shape so that the inverted triangle of the metal pins can keep in contact with the contacts when the plug is inserted.
[0009] Further, the pins outside the socket housing and the wire holes of the plug housing are arranged in two evenly divided rows.
[0010] Further, a bayonet is also provided on the socket housing. The bayonet is provided with an inclined surface 10. A connecting plate is provided on the plug housing, and a wedge block is provided on the connecting plate. The wedge block is matched with the inclined surface.
[0011] Further, positioning posts are also provided on the socket housing. The positioning posts are used for the installation and positioning of the socket.
[0012] Further, the positioning posts and the pins are located on the same side of the socket housing.
[0013] Further, a plurality of the sockets are installed side by side on the PCB board, and / or installed in multiple rows up and down.
[0014] The above solution of the present utility model has the following beneficial effects:
[0015] The RJ45 connector provided by the present utility model can significantly reduce the area of the slots (ports) of the socket housing by arranging the upper and lower two rows of metal pins in the socket housing and correspondingly arranging the contacts on the plug housing. Therefore, for the panel with limited area on the switch, more network ports can be arranged, significantly improving the data transmission rate of the switch, and still ensuring the reliability and convenience of connection and transmission.

[0023] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, the technical features involved in the different implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0024] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0025] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a locking connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0026] As Figures 1-4 shown, the embodiment of the present utility model provides an RJ45 connector, including a socket and a plug. Among them, the socket includes a socket housing 1 and metal pins 2. The socket housing 1 is provided with slots 3 (i.e., ports). There are a total of eight metal pins 2, and they are evenly divided into two groups and arranged on the opposite sides of the inner wall of the slot 3. Correspondingly, the contacts 5 on the plug are divided into two rows, and four contacts 5 are arranged in each row. The upper row of contacts 5 is located on the upper surface of the plug housing 4, and the lower row of contacts 5 is located on the lower surface of the plug housing 4. Therefore, when the plug is inserted into the socket, each contact 5 can be in contact with the corresponding metal pin 2, so as to complete the network connection and realize the signal transmission.
[0027] It should be noted that in this embodiment, the socket housing 1 and the plug housing are made of plastic material, specifically PBT, PA46, etc., to provide insulation protection for the metal probe 2, contacts, etc.
[0028] As a preferred embodiment, the metal pin 2 in this embodiment is set in an inverted triangle shape, and one vertex of the inverted triangle extends outward relative to the inner wall of the socket 2, so that when the plug is inserted, one side of the inverted triangle of the metal pin 2 can maintain stable and reliable contact with the contact 5, and will not become loose due to long-term use and cause poor contact. As a preferred embodiment, in this embodiment, the depth position of the contact 5 in the groove 6 of the plug housing 1 is set so that the metal pin 2 just inserts into the groove 6 to contact the contact and maintain an appropriate pressure.
[0029] Of course, in other embodiments, the metal pin 2 can also be set in other shapes, such as trapezoid, etc. The aforementioned inverted triangle shape is only a preferred embodiment and is not intended to limit this.
[0030] Among them, the metal pin 2 is connected to the pin 8 extending outside the socket housing 1 through the connection wire 7 embedded in the socket housing 1. The pin 8 can be soldered to the PCB board of the switch to achieve electrical connection, so that the socket is electrically connected to the PCB board. Of course, the connection wire 7 inside the socket housing 1 and the pin 8 outside can both be regarded as part of the metal pin 2 and are made of the same material. Correspondingly, one end of the connection wire 7 in the plug housing 4 is connected to the corresponding contact 5, and the other end of the connection wire 7 is led out from the wire hole of the plug housing 4 (i.e., as part of the network cable). Among them, for the convenience of internal wiring, the pins 8 outside the socket housing 1 and the wire holes of the plug housing 4 are also arranged in two rows evenly.
[0031] In this embodiment, a bayonet 9 is also provided on the socket housing 1, and the bayonet 9 is provided with an inclined surface 10. Correspondingly, a connecting plate 11 is provided on the plug housing 4 and a wedge 12 is integrally provided on the connecting plate 11. The wedge 12 is matched with the inclined surface 10. When the plug is inserted, the wedge 12 is stressed under the action of the edge of the socket 3, causing the connecting plate 11 to deform until the wedge 12 moves to the position of the bayonet 9 and the deformation is restored, and the wedge 12 is clamped into the bayonet 9, ensuring the stable connection between the plug and the socket. When the plug needs to be pulled out, just press the end of the connecting plate 11 still outside the socket 3 to make the wedge 12 withdraw from the bayonet 9, and the operation of pulling out the plug can be equally convenient.
[0032] As a preferred embodiment, in this embodiment, a positioning post 13 is further provided on the socket housing 1. The positioning post 13 is used for positioning when the socket is installed on the PCB board. Among them, the positioning post 13 can also be made of plastic material and can be integrally provided with the socket housing 1. In addition, the positioning post 13 and the pin 8 are on the same side of the socket housing 1 for positioning and electrical connection when installed with the PCB board.
[0033] It should be noted that multiple sockets in this embodiment can also be installed side by side on the PCB board or in multiple rows up and down, which is adapted to the PCB board of the switch. The RJ45 connector provided in this embodiment can significantly reduce the area of the slot 3 (port) of the socket housing 1 (the width is significantly reduced and the height may not increase significantly) by arranging the metal pins 2 in two rows up and down in the socket housing 1 and corresponding setting of the contacts 5 on the plug housing 4. Therefore, for the limited-area panel on the switch, more network ports can be arranged, significantly improving the data transmission rate of the switch, and still ensuring reliable and convenient connection transmission.
[0034] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0035] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
