Description

A connector

This application relates to the field of connector technology, and in particular to the structural design of the tail portion of a connector terminal housing.

Connectors are primarily used in computer peripherals, servers, routers, switching equipment, and other products for data transmission and peripheral device connections. They are widely used in networking, communications, automation, and other fields.

As electronic products become increasingly versatile and the market diversifies, the demands for RJ45 connectors are increasing. This has led to increasingly stringent requirements for connector stability, necessitating the addition of terminal retention structures to protect the connectors. This increased alignment requirement is a key factor in the conventional design, which uses round pins inserted from the top. This design lacks both secure engagement and accurate alignment. Furthermore, conventional designs require adhesive tape at the rear of the mold shell, increasing production costs.

To address the problems of existing technologies, the present invention aims to provide a connector with improved alignment. The square-shaped PIN structure is inserted from the bottom, and the bottom is chamfered to facilitate PIN insertion. The chamfered bottom square PIN design also facilitates assembly.

To achieve the above objectives, the present invention adopts the following technical solution: a connector comprising a housing, a base disposed within the housing, a socket disposed at one end of the base, an opening disposed at the end of the base remote from the socket, an insulating body embedded in the opening, the end (one side) of the insulating body remote from the socket being disposed in contact with the rear wall of the housing; an insulating boss disposed at the end of the insulating body near the rear wall, a pin terminal disposed at a rear end of the insulating body near one side of the insulating boss, and a protective distance D (anti-smash distance) disposed between the protruding portion of the pin terminal at the rear end of the insulating body near the insulating boss and the insulating boss.

Furthermore, in some embodiments, the insulating boss is a right-angled trapezoid, with the outer sidewall of the insulating boss parallel to the outer sidewall of the insulating body. A (right-angled trapezoidal) inclined surface is provided on the side of the insulating boss facing the pin terminal at the rear end of the insulating body, and a protective distance D is provided between the pin terminal at the rear end of the insulating body and the insulating boss.

Furthermore, in some embodiments, a protective distance D is provided between the tail pin terminal extension and the insulating boss, and the protective distance D (anti-smash distance) is 2-7 mm.

Furthermore, in some embodiments, the insulating body is provided with a through positioning slot, which has a tapered structure toward the receiving cavity. A second latch is provided in the lower section of the positioning slot (farther from the receiving cavity), while a first latch is provided in the upper section of the positioning slot (closer to the receiving cavity). The width of the second latch is greater than that of the first latch, forming a tapered structure.

Furthermore, in some embodiments, a pin terminal is passed through the positioning slot. A first latching tooth is provided on the upper portion of the pin terminal passing through the positioning slot, and a second latching tooth is provided on the lower portion of the pin terminal passing through the positioning slot, and the second latching tooth is wider than the first latching tooth.

Furthermore, in some embodiments, the bottom of the insulating body is located at the bottom of the opening of the base. A receiving cavity is provided in the insulating body, with the opening end of the receiving cavity facing the top of the base (farthest from the opening). A circuit board is provided on the opening end of the receiving cavity. A plurality of pin terminals are provided on the side walls of the insulating body, extending through the insulating body; some of the pin terminals are connected to the circuit board.

Furthermore, in some embodiments, the sidewalls of the insulating body are provided with lead grooves extending from the top (where the pin terminals extend) toward the receiving cavity. The lead grooves are connected to the receiving cavity. A welding groove (wire management groove) is provided above the insulating body where the pin terminals extend. The welding groove is located at the upper end of the lead groove. The leads of the electrical components in the receiving cavity pass through the lead groove (by winding and welding) and are then placed in the welding groove (wire management groove). The ends of the pin terminals extending from the insulating body are designed with chamfers.

This application applies to network connectors with and without transformers, as well as various configurations, such as 1×1, 1×N, and 2×N. This invention adds a boss to the rear end of the insulating body to improve the pressure resistance of the rear Phy PIN and the iron shell. With the rear insulation boss, the adhesive tape can be eliminated. This invention also improves alignment by inserting a square PIN from the bottom. The square PIN has a tapered structure and a chamfered bottom for easier insertion.

See Figure 2, which is a three-dimensional schematic diagram of an embodiment of a connector of the present application. The present application includes a housing 11, a base 13 is provided within the housing 11, and a socket 18 is provided at one end of the base 13.

Furthermore, as shown in FIG3 , FIG3 shows a schematic diagram of the structure of an embodiment of the connector of the present application; the base 13 is provided with an opening 14 at one end away from the socket 18, and an insulating body 15 is embedded in the opening 14. The end (one side) of the insulating body 15 away from the socket 18 is abutted against the rear wall 12 of the housing 11; the bottom of the insulating body 15 is located at the bottom of the opening 14 of the base 13. The insulating body 15 defines a receiving cavity 28. As shown in FIG1 , the opening of the receiving cavity 28 faces the top of the base 13 (e.g., the opening of the receiving cavity 28 faces the end of the base 13 away from the opening 14). As shown in FIG4 , a circuit board 17 is positioned above the opening of the receiving cavity 28. A plurality of pin terminals 21 extending through the insulating body 15 are provided on the sidewalls of the insulating body 15.

Furthermore, an insulating boss 16 is provided at one end of the insulating body 15 near the rear wall 12. Preferably, the insulating boss 16 is a right-angled trapezoid, and the outer side wall of the insulating boss 16 is parallel to the outer side wall of the insulating body 15. The insulating boss 16 is provided with an inclined surface on one side facing the pin terminal 21 (for example, the inclined surface is the inclined surface of the right-angled trapezoidal boss 16). A protective distance D (anti-shock distance) is provided between the extension of the tail pin terminal 21 on the insulating body 15 near the side of the insulating boss 16 and the insulating boss 16; as shown in FIG5, the tail pin terminal A protective distance D is provided between the insulating boss 16 and the rear wall 12 of the housing 11. The insulating boss 16 separates the rear wall 12 of the housing 11 from the terminal 21 at the rear end. In other words, the insulating boss 16 separates the rear wall 12 of the housing 11 from the terminal 21 on the insulating body 15 (at the rear end) near the rear wall 12. The insulating boss 16 increases the distance between the exposed terminal 21 and the rear wall 12 (the steel housing), thereby improving the withstand voltage of the terminal 21 (the pin) and the rear wall 12 (the housing 11 is made of steel).

Alternatively, please refer to Figures 6 to 8 at the same time. A through positioning groove 25 is provided on the insulating body 15. The positioning groove 25 is provided with a gradual structure toward the accommodating cavity 28. That is, the positioning groove 25 is provided with a gradual structure toward the accommodating cavity 28. The lower section of the positioning groove 25 (the section far from the accommodating cavity 28) is provided with a second latch 26, and the upper section of the positioning groove 25 (the section close to the accommodating cavity 28) is provided with a first latch. The second latching position 26 is wider than the first latching position 27, forming a tapered structure. The upper portion of the pin terminal 21 inserted into the positioning slot 25 is provided with a first latching tooth 22 that mates with the first latching position 27. The lower portion of the pin terminal 21 inserted into the positioning slot 25 is provided with a second latching tooth 23 that mates with the second latching position 26. The width of the second latching tooth 23 is wider than the width of the first latching tooth 22, forming a two-stage snap-fit positioning system.

Optionally, the sidewall of the insulating body 15 is provided with a lead slot 19 extending from the top (where the pin terminals 21 extend) toward the accommodating cavity 28. The lead slot 19 communicates with the accommodating cavity 28. A welding groove 24 (wire management groove) is provided above the point where the pin terminals 21 extend out of the insulating body 15. The welding groove 24 is located at the upper end of the lead slot 19. The leads of the electrical components in the accommodating cavity 28 pass through the lead slot 19 (by winding and welding) and are then placed in the welding groove 24 (wire management groove).

Furthermore, a protective distance D (anti-smash distance) is provided between the extension of the tail pin terminal 21 and the insulating boss 16. The protective distance D (anti-smash distance) is 2-7mm.

The insulating boss 16 is used to increase the distance between the pin terminal 21 (exposed terminal) and the rear wall 12 of the iron shell. This improves the pressure resistance of the tail pin terminal 21 (PIN) and the shell 11 (the rear wall 12 of the iron shell). The end of the pin terminal 21 extending from the insulating body 15 is designed with a chamfer 29.
