DETAILED DESCRIPTION

[0025] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Now, the preferred embodiments of the present application will be described in detail with reference to the drawings.

[0026] The network connector provided by the embodiments of the present application comprises a main shell, a circuit board and a crystal head female seat. Figures 1 to 4 The network connector comprises a main shell 1, a circuit board 2 and a crystal head female seat 3. The circuit board 2 is installed in the main shell 1, and the crystal head female seats 3 are installed at both ends of the main shell 1 and electrically connected with the circuit board 2.

[0027] The main shell 1 is provided with an insertion slot 121 at both ends, and the PIN pins 5 of the crystal head female seats 3 and 4 are located in the insertion slot 121. The PIN pin 5 comprises an arch portion 51, which has an arch top portion 511 and an inclined section 512 located on one side close to the outer side of the insertion slot 121. The arch top portion 511 and at least part of the inclined section 512 are arched and exposed in the insertion slot 121.

[0028] The existing network connector with an RJ45 interface or an RJ11 interface and the like crystal head female seat has only the arch top portion 511 of the metal PIN pin 5 exposed in the insertion slot 121. During the insertion of the external connector in the crystal head female seat, the instantaneous contact point and the contact point during stable connection are all on the arch top portion 511 of the metal PIN pin 5. In this way, when there is POE (Power over Ethernet) power supply, the instantaneous contact point will have electric arc spark, and the PIN pin 5 has the risk of blackening or even high-temperature fusing, which is more obvious with higher POE power supply, and seriously affects the function and service life of the network connector.

[0029] The utility model discloses crystal head female seat 3's PIN needle 5 is provided with the arching part 51 through certain angle and height arching, and the arching part 51 has arching top 511 and the inclined section 512 of being located on the one side of being close to the outside of the slot 121, that is, compared with the network connection head of prior art, the utility model discloses crystal head female seat 3 when the external connector is inserted into the slot 121, first contact the contact point on the inclined section 512 in the moment of contact, and after being inserted in place and stably connected, the stable connecting point is on the arching top 511, realizes the dislocation of the contact point and the stable connecting point in the moment of connection, even if the inclined section 512 appears electric arc spark phenomenon, also not easy to cause the blackening of the arching top 511 even high-temperature fuse, and after stable connection, not easy to influence network connection head function and service life.

[0030] Specifically, when the external connector is inserted into the slot 121, the external connector PIN foot first abuts against the inclined section 512, and continues to be inserted, and the PIN needle 5 is compressed and shrunk, and after the external connector is inserted in place, the arching top 511 abuts against the PIN foot on the external connector, to realize stable connection. POE power supply (Power over Ethernet) is a technology for transmitting data and power through an Ethernet cable (Cat5, Cat5e, Cat6, etc.), using some pairs of twisted pairs to transmit direct current, and using other pairs of wires to transmit data. POE technology allows some IP-based terminal devices (such as IP phones, wireless APs, network cameras, etc.) to be powered by the network cable without changing the existing Ethernet wiring architecture.

[0031] Specifically, the crystal head female seat 3 is an RJ45 interface or an RJ11 interface. The RJ45 interface 3 is usually used for Ethernet connection to transmit data, and has a plurality of metal PIN needles 5. The RJ11 interface 4 is mainly used for telephone line (PSTN) connection, and has a plurality of metal PIN needles 5. After the external connector is inserted into the slot 121, the PIN needle 5 of the RJ45 interface 3 or the RJ11 interface 4 is connected, and the PIN needle 5 is generally arranged in an arch shape, so as to have a certain elasticity, to ensure stable connection with the external connector.

[0032] Specifically, as shown in Figure 4As shown, the angle a between the surface of the inclined section 512 corresponding to the slot 121 is 26°-30°. By setting the angle a between the inclined section 512 and the slot 121 to 26°-30°, the contact sequence of the external connector PIN pin and the network connector PIN pin 5 can be controlled, so that the external connector PIN pin first contacts the inclined section 512 instead of directly contacting the arched top 511, thereby realizing the misalignment of the contact point. Therefore, when the external connector is inserted, due to the existence of the inclined section 512 with an angle a of 26°-30°, even if an arc spark is generated, it occurs on the inclined section 512 instead of the arched top 511. In this way, the influence of the arc spark on the arched top 511 can be reduced, and the risk of blackening and melting can be reduced.

[0033] Further, the height h of the surface of the arched top 511 to the inclined section 512 corresponding to the slot 121 is 1.5mm-2.0mm. Further controlling the height h of the surface of the arched top 511 to the inclined section 512 corresponding to the slot 121 to be 1.5mm-2.0mm can ensure that the arched top 511 is at a higher point, further ensure the contact sequence and contact point of the external connector PIN pin and the network connector PIN pin 5, and ensure that the external connector PIN pin first contacts the inclined section 512 and then contacts the arched top 511, thereby realizing the misalignment of the contact point.

[0034] Further, in the axial direction of the main shell 1, the circuit board 2 is vertically arranged in the main shell 1, one crystal head female seat 3 is installed on one side of the circuit board 2, and the other crystal head female seat 3 is installed on the other side of the circuit board 2. The existing circuit board 2 of the network connector with an RJ45 interface 3 or an RJ11 interface 4 or the like crystal head female seat is generally horizontally arranged, i.e. arranged parallel to the axial direction of the main shell 1, and the two ends of the RJ45 interface 3 or the RJ11 interface 4 are respectively welded on the two ends of the circuit board 2. Such arrangement makes the size of the circuit board 2 larger (about 36mm in length and 18mm in width), which is not conducive to the miniaturization of the network connector; and the length of the copper wire on the circuit board 2 is longer, the signal transmission process has larger attenuation, and the stability of signal transmission is poorer. The present scheme arranges the circuit board 2 vertically in the main shell 1, and two crystal head female seats 3 are respectively arranged on the two sides of the vertically arranged circuit board 2, which can reduce the size of the circuit board 2, facilitate the miniaturization of the network connector, and reduce the length of the copper wire after the size of the circuit board 2 is reduced, thereby reducing the attenuation in the signal transmission process and improving the stability of signal transmission. Figure 4

[0035] ​Specifically, the width of the circuit board 2 is 11mm-13mm, and the height is 13mm-15mm. The width of the circuit board 2 is 11mm-13mm, and the height is 13mm-15mm in the present scheme, which helps to ensure the adaptability of the circuit board 2 to the main shell 1, while providing sufficient space for the layout of the elements on the circuit board 2. Specifically, the width of the circuit board 2 is 12mm, and the height is 14mm.

[0036] Further, the main shell 1 comprises an outer shell 11 and an inner shell 12, the outer shell 11 wrapping the inner shell 12, the insertion slots 121 being formed at both ends of the inner shell 12, the circuit board 2 being installed in the inner shell 12, and the crystal head female seat 3 being installed at both ends of the inner shell 12. The design of the outer shell 11 wrapping the inner shell 12 provides necessary mechanical protection for the internal circuit board 2 and the crystal head female seat 3, reducing damage to sensitive electronic elements caused by external impact and pressure. The double-layer shell structure can improve the durability of the network connector and prolong the service life of the network connector. Specifically, the insertion slots 121 are formed at both ends of the inner shell 12, the wall surface of the insertion slot 121 is provided with a slot 122, and the arched top 511 and the inclined section 512 of the PIN pin 5 are exposed in the insertion slot 121 through the slot 122.

[0037] The inner shell 12 is sleeved with an end sleeve shell 13 at both ends, the end sleeve shell 13 is provided with elastic pressing pieces 131 on both sides, and the insertion slot 121 is provided with a receiving groove 121a corresponding to the elastic pressing piece 131; the elastic pressing piece 131 extends into the insertion slot 121 and is located in the receiving groove 121a. When the external connector is inserted into the insertion slot 121, the elastic pressing piece 131 can press the external connector tightly to ensure that the external connector is stably inserted into the insertion slot 121 and ensure the stability of the connection.

[0038] Further, the elastic pressing piece 131 has an elastic arching part 131a, which arches towards the middle region of the insertion slot 121. The elastic arching part 131a can provide sufficient elastic pressing force for the elastic pressing piece 131 to ensure the pressing of the external connector. Specifically, the elastic pressing piece 131 is a metal pressing piece.

[0039] Specifically, the PIN pin 5 of the crystal head female seat 3 is provided with a plurality of PIN pins 5, which are arranged side by side in the insertion slot 121.
