Description

Technical Field

[0001] The utility model relates to the technical field of communications, and in particular to a network port connector and communication equipment. Background Art

[0002] At present, the DIP (Dual In-line Package) RJ45 connector used in data communication equipment requires manual insertion of the device into the PCB (Printed Circuit Board) and then wave soldering, which is inefficient and difficult to achieve automated operation.

[0003] In order to achieve automated mounting and improve efficiency, SMT (Surface Mount Technology) RJ45 connectors are increasingly being used in data communication equipment. After the SMT RJ45 connector is soldered, due to the low adhesion of the bent pin pads on the PCB, the RJ45 connector may be bumped during production and the network cable may be pulled during use by customers. This may easily cause the pin pads of the SMT RJ45 network port connector to peel off from the PCB, posing a quality risk.

[0004] In order to improve the adhesion between the bent pins and the pads of the SMT RJ45 connector after soldering, the current countermeasure is to perform glue dispensing after passing through a high-temperature furnace, which consumes manpower and material resources.

[0005] A related technical solution is to use symmetrical pins (1 pair or 2 pairs) instead of bent pins. This solution can realize automated mounting and improve the adhesion between the RJ45 connector and the PCB after soldering. However, the usage scenarios are limited and are only applicable to the case where there is an RJ45 connector on one side of the PCB, and cannot be used in the case where RJ45 connectors need to be soldered on both sides of the PCB: the RJ45 connector on the upper surface and the RJ45 connector on the lower surface share the PTH hole (Plating Through Hole) of the PCB, because the pins of the RJ45 connector on the upper surface of the PCB will overlap and interfere with the pins of the RJ45 connector on the lower surface of the PCB; on the other hand, before passing through the reflow oven, solder paste can only be applied to one side of the PCB (upper or lower surface), and then the RJ45 connector is placed, and then passed through the reflow oven. After passing through the reflow oven, there is a situation where the solidified solder blocks the PTH hole, resulting in the inability to insert the pins of the RJ45 connector under the PCB into the shared PTH hole. Therefore, the symmetrical pin-type RJ45 connector cannot be used in the case where RJ45 connectors need to be soldered on both sides of the PCB. Utility Model Content

At the same time, since the two opposite network port connectors will not share the electroplated through hole, even if the solder paste in the electroplated through hole corresponding to the network port connector installed first is solidified, it will not affect the installation of the network port connector installed later on the other side.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Combination Figures 1 to 5 :

[0031] The network port connector provided in the embodiment of the present application can be a connector with network communication function such as an RJ (Registered Jack) 45 connector, and the network port connector includes: a shell 30, the shell 30 has a socket U facing the plug-in direction T, one end of the bottom surface of the shell 30 in the width direction W has M first pins 10, and the other end has N second pins 20, M and N are both positive integers greater than or equal to 1, and the width direction W is perpendicular to the plug-in direction T; along the width direction W, the projections of the M first pins 10 and the projections of the N second pins 20 do not overlap.

[0032] When the two above-mentioned network port connectors are relatively arranged on both sides of the circuit board 50, the electroplated through hole corresponding to the first pin 10 of the top side network port connector and the electroplated through hole corresponding to the second pin 20 of the bottom side network port connector can be staggered with each other, and the electroplated through hole corresponding to the second pin 20 of the top side network port connector and the electroplated through hole corresponding to the first pin 10 of the bottom side network port connector can be staggered with each other, so as to avoid interference caused by the first pin 10 and the second pin 20 of the network port connectors on both sides being located in the same electroplated through hole. At the same time, since the two opposite network port connectors will not share the electroplated through hole, even if the solder paste in the electroplated through hole corresponding to the network port connector installed first is solidified, it will not affect the installation of the network port connector installed later on the other side.

[0033] The first pin 10 and the second pin 20 are respectively inserted into the corresponding plated through holes, which can improve the adhesion to the circuit board 50 compared to the bent pins mounted on the circuit board surface using the SMT technology. At the same time, since the signal pins 40 on the bottom of the housing 30 are tilted, the end portion is parallel to the bottom of the housing 30, so it is convenient to mount on the surface of the circuit board 50 using the SMT technology.

[0034] It is understandable that the network port connector can be welded on only one side of the circuit board 50, or the network port connector can be welded on both sides of the circuit board 50. Figure 6 The network port connector a and the network port connector b are arranged on both sides of the circuit board 50 and are arranged opposite to each other.

[0035] In a specific embodiment, M=N, so as to ensure that the forces on both sides of the housing 30 in the width direction W are as close as possible. It is also possible to ensure that the widths of the first pin 10 and the second pin 20 are equal, so as to ensure that the forces on both sides of the housing 30 are as close as possible, and both are between 0.4mm and 2.5mm, and specifically can be 0.4mm, 0.8mm, 1.2mm, 1.6mm, 2.1mm and 2.5mm, etc. If the width is too small, it is difficult to meet the strength requirements, the adhesion is not strong, and it is easy to fall off when pulled by the network cable; if the width is too large, it is easy to cause the electroplated through holes corresponding to the network port connectors on both sides of the circuit board 50 to interfere with each other.

[0036] refer to Figure 1 and Figure 4 In a specific embodiment, M=1, N=1. A first pin 10 and a second pin 20 are arranged on both sides of the housing 30 in an asymmetrical manner in the width direction W. With a relatively simple structure, both sides of the housing 30 in the width direction W can be ensured to be fixedly connected to the circuit board 50, while at the same time, the first pin 10 corresponding to the network port connector a and the second pin 20 of the network port connector b on both sides of the circuit board 50, as well as the second pin 20 corresponding to the network port connector a and the first pin 10 of the network port connector b, can be prevented from interfering with each other.

[0037] In a specific embodiment, Figure 1 and Figure 4 In the insertion and removal direction T, the distance between the first pin 10 and the second pin 20 is between 2 mm and 6 mm, and can be 2 mm, 4 mm, 6 mm, etc. Figure 5 and Figure 6If the above distance is too close, the first electroplated through hole 51 corresponding to the first pin 10 of the network port connector a and the second electroplated through hole 52 corresponding to the second pin 20 of the network port connector b are too close or even overlapped, the first pin 10 and the second pin 20 are not stably fixed, and when the first pin 10 of the network port connector a is soldered, the solder paste easily enters the second electroplated through hole 52 corresponding to the second pin 20 of the network port connector b; if the above distance is too large, when the first pin 10 of the network port connector a is pulled by the network cable, the second pin 20 farther away from the network cable is difficult to resist the pulling of the network cable.

[0038] refer to Figure 2 In a specific embodiment, M=2, N=2, the projection of the two first pins 10 in the width direction W is located between the projections of the two second pins 20 in the width direction W, when the network port connector a and the network port connector b are arranged on both sides of the circuit board 50, the first electroplated through holes 51 corresponding to the two first pins 10 of the network port connector a are located between the second electroplated through holes 52 corresponding to the two second pins 20 of the network port connector b, and it is not easy to form interference. In addition, since the number of the first pins 10 and the second pins 20 are both two, the network port connector a and the network port connector b are not easy to swing back and forth in the plug-in direction T, and the network port connector a and the network port connector b can be fixed more firmly.

[0039] In a specific embodiment, the distance between the two first pins 10 is between 2 mm and 4 mm, such as 2 mm, 3 mm and 4 mm. If the above distance is too close, the first electroplated through hole 51 corresponding to the network port connector a and the second electroplated through hole 52 corresponding to the network port connector b are too close or even overlapped, which affects the stability of the first pin 10 and the second pin 20. In addition, when soldering the first pin 10 of the network port connector a, the solder paste easily enters the second electroplated through hole 52 corresponding to the second pin 20 of the network port connector b. If the above distance is too large, the network port connector a and the second electroplated through hole 52 corresponding to the second pin 20 of the network port connector b are too close to each other. When the first pin 10 of the network connector a is pulled by the network cable, the second pin 20 which is farther away from the network cable can hardly resist the pulling of the network cable. In addition, the distance between the two second pins 20 is too far; the distance between the two second pins 20 is between 5mm and 8mm, such as 5mm, 6mm, 7mm and 8mm. If the distance between the two second pins 20 of the network connector a is too small, correspondingly, the space between the two second pins 20 available for the two first pins 10 of the network connector b is too small, and even interference between the two may occur.

[0040] In a specific embodiment, the shell 30 is provided with a first bent pin 11 corresponding one-to-one to the first pin 10, and a second bent pin 21 corresponding one-to-one to the second pin 20. The first bent pin 11 can be an integral structure with the first pin 10, and the second bent pin 21 can be an integral structure with the second pin 20. Each first bent pin 11 and a second bent pin 21 are arranged opposite to each other along the width direction W; along the plug-in direction T, each first pin 10 is connected to an end of the corresponding first bent pin 11 away from the opening of the socket U, and each second pin 20 is connected to an end of the corresponding second bent pin 21 close to the opening of the socket U.

[0041] The first bent pin 11 and the second bent pin 21 can be mounted on the surface of the circuit board 50 using SMT technology to increase the contact area with the circuit board 50 and improve the adhesion. In addition, the first bent pin 11 and the second bent pin 21 are arranged relative to each other, which can make the force positions of the two ends of the housing 30 in the width direction W tend to be consistent to a certain extent, which is conducive to the force balance on both sides. However, the first pin 10 and the second pin 20 can be staggered in the plug-in direction T to prevent the first pin 10 of the network port connector a and the second pin 20 of the network port connector b from interfering with each other.

[0042] In a specific embodiment, M=1, N=2, and the projection of a first pin 10 in the width direction W is located between the projections of two second pins 20 in the width direction W. A first pin 10 of the network port connector a is located between two second pins 20 of the network port connector b, and the network port connector a has three fixing points, namely, a first pin 10 and two second pins 20, and is not easy to swing back and forth in the plugging direction T, which is conducive to improving the adhesion. And, relative to Figure 2 The first pin 10 is simplified to one, which is conducive to maintaining a sufficient distance from the two second pins 20 of the opposite side network port connector to avoid interference.

[0043] In a specific embodiment, the distance between the two second pins 20 is between 2.5 mm and 8 mm, and can be 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, etc. If the above distance is too small, the first pin 10 of the network port connector a and the second pin 20 of the network port connector b will be too close to each other, which may easily cause interference, and when the first electroplated through hole 51 corresponding to the first pin 10 of the network port connector a is filled and cured, the solder paste is not easy to enter the second electroplated through hole 52 corresponding to the second pin 20 of the network port connector b.

[0044] In a specific embodiment, along the plug-in direction T, the first plug pin 10 is equidistant from the two second plug pins 20 , so as to ensure that the housing 30 is subjected to balanced force in the plug-in direction T when the network cable is plugged in or out.

[0045] exist Figure 1 , Figure 2 and Figure 4 In the embodiment, the first pin 10 and the second pin 20 can be rectangular metal sheets perpendicular to the bottom surface of the housing 30, and the rectangular metal sheets can be chamfered to facilitate insertion into the corresponding plated through holes. Figure 5 The first pin 10 and the second pin 20 are both of a clamp-type structure, that is, they both include two legs spaced apart, and a guide groove is formed at one end away from the housing 30 to facilitate guiding into the corresponding electroplated through hole. At the same time, when entering the corresponding electroplated through hole, the distance between the two legs shrinks, and after entering the electroplated through hole, they will expand to be stuck in the electroplated through hole.

[0046] Based on the same idea, refer to Figure 6 and Figure 7 The embodiment of the present application also provides a communication device, which includes a circuit board 50 and a plurality of network port connectors provided in the above embodiment. The circuit board 50 can be a PCB (Printed Circuit Board), and the circuit board 50 is provided with a plurality of first electroplated through holes 51 and a plurality of second electroplated through holes 52; a plurality of network port connectors are arranged on both sides of the circuit board 50, and each first pin 10 is plugged into a corresponding first electroplated through hole 51, and each second pin 20 is plugged into a corresponding second electroplated through hole 52; wherein at least one pair of network port connectors are arranged oppositely, and in each pair of oppositely arranged network port connectors, the first electroplated through hole 51 corresponding to one network port connector and the second electroplated through hole 52 corresponding to another network port connector do not overlap. Its beneficial effects can refer to the relevant description of the network port connector in the above text.

[0047] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
