Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to an RJ45 type electrical connector. Background Art

[0002] With the advent of the information age, the network has developed rapidly. At the same time, network connectors have been widely used. Network connectors are a type of information socket (i.e., communication lead-out terminal) connectors in wiring systems. The connector consists of a plug (connector, crystal head) and a socket (module). The plug has 8 grooves and 8 contacts. The network connector is connected between the wires through the plug and the socket to achieve electrical continuity of the wires. Whether now or in the future, network connectors occupy an important position in the era, and their application and development prospects are very good.

[0003] At present, network connectors are still under continuous development and improvement. At this stage, network connectors can be divided into single-cell network connectors and multi-cell network connectors according to the number of sockets. The specifications can be selected according to the usage requirements of different users. The common single-layer multi-cell RJ45 network connectors on the market are generally composed of a plastic body, a shielding shell and a number of lower terminals. Although the plastic body adopts a multi-cell integral integrated design, many holes are opened on the back, and the dustproof performance is low in practical applications; and the shielding shell is mostly a full-enclosed design. In actual use, the inventor found that the electromagnetic interference is generated only in the front half of the plastic body, and the part located at the rear half of the plastic body cannot play the due shielding role and wastes materials. Although the traditional half-enclosed network connector adopts a plurality of buckle structure designs, it can ensure the connection strength between the shielding shell and the insulating seat to a certain extent. However, due to the relatively limited buckle force, and after the connector is plugged in and out for many times, the shielding shell and the insulating seat will still become loose, thereby affecting its shielding performance and life.

[0004] Therefore, it is urgent to develop a structure that improves the existing RJ45 network interface connector to solve the above problems. Summary of the invention

The clamping blocks 251 are combined with the lower terminal seat 32 to ensure that the lower terminal seat 32 does not loosen when combined with the insulating seat 20, so as to avoid affecting the electrical performance of the terminal seat 30. The two opposite side plates 23 of the present invention are provided with external clamping grooves 231 (such as Figure 5), and a tenon 232 for the step-shaped limiting portion 1231 to fit with the side plate 23 is provided to engage with the shield shell 10, and a locking edge 2631 is provided on the cross arm 263 corresponding to each upper port 2611 and each lower port 2621, and a tooth groove 2632 is provided at the inner edge of the locking edge 2631, and the number of the tooth grooves 2632 is adapted to the number of the upper terminals 312. Among them, the present invention is provided with a baffle 264 between each upper port 2611 (i.e., the "front") and each corresponding upper assembly cavity (i.e., the "rear") and between each lower port 2621 (i.e., the "front") and each corresponding lower assembly cavity (i.e., the "rear"), the baffle separates the front and the rear, and a gap is formed between the baffle 264 and the cross partition, and the baffle 264 is provided with an opening groove 2641 that opens toward the gap and connects the front and the rear, so as to facilitate the upper terminal 312 to pass through and limit its positioning.

[0044] To explain the structure of the shielding shell 10 in detail (please refer to Figure 3 and Figure 4 ), the shielding shell 10 in the figure includes a front 11 and a shell 12 extending vertically from the front, multiple external elastic arms 121, multiple shell feet 124 and multiple internal elastic arms 1121, multiple external elastic arms 121 are arranged on the outer surface of the shell 12, and multiple external elastic arms 121 are arranged around to improve the grounding stability of the connector when it is installed in an external chassis. Figure 5 In the invention, a transverse rib 111 is provided in the middle of the shielding shell 10, and the two side plates of the transverse rib 111 are bent inward to form a card edge 1111 adapted to the card edge 2631, so as to increase the connection stability between the shielding shell 10 and the insulating seat 20. At the same time, in order to reduce the weight of the insulating seat 20, realize the lightweight of the product, and improve its heat dissipation effect, the present invention also provides a groove (not marked) on the cross arm 263. When the shielding shell 10 is covered on the insulating seat 20, at this time, the cross arm 263 on the shielding shell 10 covers the groove (not marked). In this way, the heat can also be dissipated through the shielding shell 10 to achieve rapid heat dissipation. Figure 6In the embodiment, both sides of the shielding shell 10 are provided with inwardly recessed snaps 122, which are matched with the corresponding outer slots 231 of the side walls of the insulating seat 20. When the two are matched, the connection strength can be further improved by the combination of the snaps 122 and the slots to ensure the shielding effect. As a preferred embodiment of the present invention, the present invention also extends outwardly at the lower middle part of the side plate of the shielding shell 10 to form a connecting edge 123, and the two side surfaces of the insulating seat 20 are provided with limiting parts 1231 that are matched with the side plates of the shielding shell 10 and the connecting edge 123. When the two are combined, the wing-shaped connecting edge 123 can be combined with the limiting part 1231 to achieve the limited positioning of the installation depth and length. It should be noted that the design of the transverse ribs 111 and the vertical ribs 112 of the shielding shell 10 can divide the shielding shell 10 into two layers, upper and lower, to form a window structure that exposes multiple upper ports 2611 and lower ports 2621 and allows external plugs (not shown) to be inserted and adapted, and to cover the peripheral structures of the upper ports 2611 and lower ports 2621, and to ensure signal shielding therein, and the inner elastic arm 1121 is arranged on each vertical rib (or "separation partition") 112, so that the external plug (not shown) can be elastically locked and positioned when plugged into the port, thereby ensuring the accuracy of the connection. In this example, the shell foot 124 is preferably arranged at the bottom of the end of the connecting edge 123 of the shielding shell 10, for adapting to the external PCB board (grounding), so as to effectively suppress internal noise and external interference, and for the convenience of installation, the present invention also provides an inserting portion 1232 on the end face of the connecting edge 123, and a tenon 232 adapted to the inserting portion 1232 is provided on the side wall of the insulating seat 20.

The lower tongue plate is suspended at the front end of the seat body and includes a lower terminal groove 3225 for the lower terminal horizontal section 3212 to be set and a lower terminal hole 3226 for the lower terminal pin section 3211 to be inserted. The lower terminal hole penetrates the vertical plate and the base plate 3222 downwardly for the lower terminal pin section 3211 to be set, so that the pin protrudes from the bottom of the base plate for the PCB board to adapt. In this example, when the lower terminal 321 is assembled with the seat body 322, the lower terminal contact section is tilted inwardly below the lower tongue plate. In this example, a rectangular frame 3227 and a plurality of ribs 3228 are raised on the back side of the vertical plate 3221 (i.e., the back side of the seat body), and a T-shaped guide portion (T) is provided on the vertical plate 3221 on both sides of the rectangular frame 3227. The rectangular frame and the end face of the corresponding positioning edge 212 of the insulating seat 20 are engaged and limited to further improve the stability of the terminal seat 30 on the insulating seat 20, thereby ensuring the stability of the assembly. At the same time, the guide portion cooperates with the plurality of ribs 3228 below the rectangular frame to realize the positioning of the lamp foot 51 of the LED lamp 50. In this example, the vertical plates of the mounting plate 3223 are provided with card protrusions (K) adapted to the card blocks 251 of the insulating seat 20 on both sides, and the lower end face of the vertical plate opposite to the vertical plate 3221 is provided with a base plate 3222, and the base plate has a structure with a larger top and a smaller bottom (such as Figure 7 , that is, the width of the substrate on the side close to the substrate 3222 is smaller than the width of the substrate on the side away from the substrate; a slider (L) adapted to the slide groove (H) of the upper terminal seat 31 is provided on one side of the concave space of the vertical plate.

During installation, the vertical portion 3112 of the upper terminal seat 31 is inserted into the concave space from top to bottom. During the insertion process, it is necessary to ensure that the pin section 3121 of the upper terminal 312 on the upper terminal seat 31 is inserted into the lower terminal hole 3226, and the slide groove (H) is adapted to the slider (L) so that the vertical portion 3112 abuts against the base plate 3222. In this example, in order to ensure the stability and prevent the upper and lower terminal seats 31 and 32 from being displaced after assembly, the present invention provides a lower clamping protrusion (X) near both sides on the lower terminal seat vertical plate on the side opposite to the vertical plate 3221, and an upper clamping protrusion (S) adapted to the lower clamping protrusion (X) is provided on the vertical portion 3112 of the upper terminal seat. The end face of the lower clamping protrusion (X) is inclined, that is, it gradually increases from top to bottom, and the inclined surface of the upper clamping protrusion (S) is a structure with a small bottom and a large top (the opposite structure of the lower clamping protrusion). When the upper terminal seat 31 and the lower terminal seat 32 are fully combined, the two (upper and lower clamping protrusions) engage with each other to limit their up and down movement. In this example, the clamping protrusion (K) engages with the block 251 of the insulating seat 20, and the two can complete the assembly. In this example, the upper terminal groove 3113 includes an upper groove (SC) (on the upper side) and a lower groove (XC) (on the lower side opposite to the upper side), and the upper groove (SC) and the lower groove (XC) are connected through the notch at the front end.

The base plate 3222 is also provided with eight guide holes for accommodating and passing through the upper terminal seat 31. There are also eight upper terminal slots 3113 on the upper tongue plate 3111, and eight guide slots 3114 on the vertical portion 3112. It is worth noting that the guide slots 3114 are staggered to form a structure of 4 in front and 4 in the back to reduce its volume.

[0048] See also Figure 1 , Figure 2 and Figure 7 See also Figures 8 to 13, the overall width of the 8 lower grooves (XC) near one end of the vertical portion 3112 in the figure is greater than the width of the 8 lower grooves (XC) at the edge of the upper tongue plate 3111. By this design, the upper terminal 312 is evenly arranged and its interference is reduced. At the same time, combined with the inclined setting of the end face of the upper groove (SC), on the one hand, it can achieve a smaller elastic deformation when subjected to force, which is convenient for clamping and improves its life. Since the spacing between the upper groove (SC) and the upper terminal groove 3113 is relatively large, in order to avoid the upper terminal 312 being subjected to superposition of forces during use, resulting in signal interference, the present invention also sets a plurality of arrow portions 3115 on the surface of the upper tongue plate 3111, and the arrow portions pass through the opening groove 2641 and interfere with the baffle 264 of the insulating seat, so that the terminal seat 30 assembled on the insulating seat will not naturally fall out.

[0049] Please continue reading Figure 1 , Figure 2 and Figure 7 , the figure has a rear clasp plate 40, which is a long strip plate body, and has reinforcing ribs 41 distributed on one side of the plate body, and the reinforcing ribs 41 are arranged at intervals to form limiting grooves 42. In this example, each terminal interface corresponds to two LED lamps 50, and each upper assembly cavity 261 and each lower assembly cavity 262 are respectively provided with two LED lamps 50, and each LED lamp 50 has a wick 51 and two lamp pins, and the lamp pin has a transverse section 52 and a longitudinal section 53. The rear clasp plate is arranged behind the terminal seat and interferes with the insulating seat, so as to prevent the terminal seat from freely withdrawing backwards in the insulating seat. In this example, each upper opening 271 and the lower opening 272 are provided with a wick 51, and the longitudinal sections 53 of the lamp pins of the upper and lower openings 271 and 272 are limited by the limiting grooves 42. Since the rear clasp plate 40 is a long thin plate, its overall strength can be improved by the design of the reinforcing ribs 41.

[0050] In order to effectively make the rear clasp plate 40 (such as Figure 7 ) is combined with the terminal base 30, and a hook 43 is provided on the rear buckle plate 40 that is in contact with the terminal base 30. The hook 43 extends to one side of the terminal base 30 and is provided with a hanging buckle 431. A connecting hole 33 adapted to the hook 43 is provided at the bottom of the vertical plate 3221 of the terminal base 30, and a buckle groove (not shown) adapted to the hanging buckle 431 is provided on the inner side surface of the connecting hole 33.

[0051] An RJ45 type electrical connector of the present invention, by adopting the two side plates of the transverse rib to bend inward to form a card edge adapted to the card edge, utilizing the connection effect between the two, combining the spring buckle on the shielding shell and the structural design of the external card slot, can effectively improve the connection strength between the semi-enclosed shielding shell and the insulating seat, while reducing the material consumption, improving its fatigue effect and enhancing its service life.
