Description

Technical Field

[0001] This utility model relates to the field of electrical connections, and more particularly to an electrical connector. Background Technology

[0002] Type-C USB connectors are widely used components in various digital and electronic products. They typically consist of an insulating plastic body, a terminal module, and a metal housing. The terminal module is usually encased within the insulating body. To achieve good signal transmission quality, existing Type-C USB connectors often include a metal isolation plate within the terminal module, sandwiched between the upper and lower rows of terminals to shield against interference signals. The metal housing surrounds the insulating body for assembly and fixation, providing shielding and protection. The terminal module includes a grounding terminal for connection with the metal isolation plate to establish a grounding circuit. However, existing metal isolation plates are typically one-piece / monolithic stamped plates. Regardless of whether the grounding terminal is damaged, the circuit remains continuous and the resistance voltage remains stable, thus failing to detect damage to the grounding terminal. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an electrical connector to improve the problem that the grounding terminal cannot be detected in time in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an electrical connector, comprising an insulating body, a terminal module housed within the insulating body, and a metal housing assembled on the insulating body. The terminal module includes an upper module, a lower module, and a metal partition sandwiched between the upper module and the lower module. The metal partition includes a pair of separately arranged inner partitions and a pair of separately arranged outer partitions. The inner partitions and outer partitions are separately arranged, and both the upper module and the lower module are provided with a pair of grounding terminals. Each grounding terminal is simultaneously connected to an adjacent inner partition and an outer partition, thereby bridging and connecting the adjacent inner partition and outer partition.

[0005] Furthermore, the pair of inner partitions are divided into a left inner partition and a right inner partition, which are asymmetrically arranged. Both have a long and narrow arm and a head extending laterally from the front end of the arm. The rear end of the arm has a tail extending backward. The arm is integrally connected between the head and the tail.

[0006] Furthermore, the head is positioned to the outside of the arm, the tail has a deflection portion extending outward, and a receiving space for accommodating the outer partition is formed between the head, arm, and deflection portion.

[0007] Furthermore, the head extends outward beyond the tail, and the head has an overlapping edge, while the tail has an extendable foot.

[0008] Furthermore, the head and tail of the right inner partition are both plate-shaped, and the area of ​​the head is larger than the area of ​​the tail, while the head of the left inner partition is plate-shaped and its tail is long and narrow.

[0009] Furthermore, the upper module is provided with a plurality of upper row terminals and an upper body fixed on the upper row terminals, and the lower module is provided with a plurality of lower row terminals and a lower body fixed on the lower row terminals. The grounding terminal is located on the outermost side of the upper row terminals and the lower row terminals.

[0010] Furthermore, the tail of the left inner partition is asymmetrically arranged with the tail of the right inner partition, while the head and arm of the left inner partition are symmetrically arranged with the head and arm of the right inner partition; the pair of outer partitions are symmetrically arranged.

[0011] Furthermore, the outer partition is L-shaped, having an inner extension extending in a front-to-back direction and an outer extension extending in a left-to-right direction. The inner extension is accommodated in the accommodating space and located on the rear side of the head. The outer extension extends integrally outward from the inner extension and beyond the head. The rear edge of the outer extension has a pair of rearwardly extending lead-out feet.

[0012] Furthermore, an upwardly protruding upper flap and a downwardly protruding lower flap are formed on the outer partition plate, which respectively abut against the grounding terminals in the upper module and the lower module.

[0013] Compared with the prior art, this utility model sets the metal partition into four independent partitions (a pair of inner partitions and a pair of outer partitions), and uses the grounding terminal to bridge and conduct the adjacent inner and outer partitions to realize the circuit path. This allows for monitoring whether the grounding terminals on both sides are damaged, thereby enabling timely detection of electrical connector faults for rapid repair or replacement.

[0018] Please see Figures 1 to 4 As shown, this utility model provides an electrical connector, including: an insulating body 10, a terminal module 20 held inside the insulating body 10, a metal housing 30 mounted on the insulating body 10, and a metal cover 40 covering the metal housing 30.

[0019] The insulating body 10 has a base 11 and a mating tongue 12 extending forward from the base 11. The two lateral ends of the base 11 protrude outward beyond the mating tongue 12 to support the metal housing 30. Additionally, the side, upper, and lower surfaces of the two lateral ends of the base 11 are provided with outwardly protruding ribs 13 to abut against the metal housing 30, achieving interference fixation with the metal housing 30. The mating tongue 12 is flat and is used to mate with a mating-end electrical connector (not shown), and the upper and lower surfaces of the mating tongue 12 support the terminal module 20.

[0020] The terminal module 20 includes an upper module 21, a lower module 22, and a metal partition 23 between the upper module 21 and the lower module 22. The upper module 21 includes a plurality of upper row terminals 210 and an upper body 211 fixed on the upper row terminals 210. The lower module 22 includes a plurality of lower row terminals 220 and a lower body 221 fixed on the lower row terminals 220. The plurality of upper row terminals 210 and the plurality of lower row terminals 220 are arranged in a one-to-one correspondence. Each of the plurality of upper row terminals 210 and the plurality of lower row terminals 220 includes a pair of grounding terminals 210G and 220G located on the outermost side. The grounding terminal 210G in the upper row terminal 210 and the grounding terminal 220G in the lower row terminal 220 are arranged in a one-to-one correspondence. Preferably, the upper body 211 and the lower body 221 are both formed on the upper row of terminals 210 and the lower row of terminals 220 by injection molding process, forming the upper module 21 and the lower module 22.

[0021] The metal partition 23 is preferably four independent partitions, specifically including: a pair of separate inner partitions 24 and a pair of separate outer partitions 25. The pair of inner partitions 24 are arranged adjacent to each other, and the pair of outer partitions 25 are respectively located on both sides of the pair of inner partitions 24. Figure 3As shown, the pair of inner partitions 24 are divided into a left inner partition 24A and a right inner partition 24B, which are asymmetrically arranged. Both have a long and narrow arm 26 and a head 27 extending laterally from the front end of the arm 26. The rear end of the arm 26 has a tail 28 extending rearward. The arm 26 is integrally connected between the head 27 and the tail 28. The head 27 is biased to the outside of the arm 26. The tail 28 has a biased portion 280 extending outward. A receiving space 29 is formed between the head 27, the arm 26 and the biased portion 280 to receive the outer partition 25. Preferably, the head 27 extends outward beyond the tail 28 and has an overlapping edge 271 for overlapping the grounding terminals 210G and 220G. The tail 28 has a lead-out foot 281. Preferably, the head 27 and tail 28 of the right inner partition 24B are both plate-shaped, and the area of ​​the head 27 is larger than the area of ​​the tail 28. The head 27 of the left inner partition 24A is plate-shaped, and the tail 28 is long and narrow with a lead-out foot 281. That is, the tail 28 of the left inner partition 24A and the right inner partition 24B are asymmetrically arranged, while the head 27 and arm 26 of the left inner partition 24 are symmetrically arranged with the head 27 and arm 26 of the right inner partition 24. The pair of outer partitions 25 are located symmetrically on the outer side of the arm portion 26. Specifically, the outer partition 25 is L-shaped, with an inner extension 251 extending in a front-to-back direction and an outer extension 252 extending in a left-to-right direction. The inner extension 251 is accommodated in the accommodating space 29 and is located behind the head 27 of the pair of inner partitions 24. The outer extension 252 extends integrally outward from the inner extension 251 and exceeds the head 27 of the pair of inner partitions 24. The rear edge of the outer extension 252 also has a pair of rearwardly extending lead-out feet 281. The lead-out feet 281 of the pair of inner partitions 24 and the lead-out feet 281 of the pair of outer partitions 25 form a row.

[0022] In a preferred embodiment of this utility model, in order to achieve good contact and conduction with the grounding terminals 210G and 220G, an upwardly protruding upper flap 253 and a downwardly protruding lower flap 254 are formed on the outer partition plate 25, which respectively abut against the upper grounding terminal 210G and the lower grounding terminal 220G. Figure 3The diagram shows only the upper grounding terminal 210G for illustration only, omitting the lower grounding terminal 220G. The upper flap 253 and lower flap 254 are located between the upper grounding terminal 210G and the lower grounding terminal 220G, respectively. Each grounding terminal 210G and 220G simultaneously overlaps an inner partition 24 and an outer partition 25. Specifically, the front end of each grounding terminal 210G and 220G overlaps the overlapping edge 271 of the inner partition 24, while the middle portion of each grounding terminal 210G and 220G overlaps the upper flap 253 or the lower flap 254. This allows the inner partition 24 and its adjacent outer partition 25 to be bridged and connected through the grounding terminals 210G and 220G, establishing a circuit path.

[0023] The inner partition 24 and the outer partition 25 overlap and cooperate with the grounding terminals 210G and 220G to form a shape as shown in the figure. Figure 4 In the circuit path shown, under normal operating conditions, the grounding terminals 210G and 220G and the detection pin (i.e., lead-out pin 281) of the inner partition 24 are always in a connected state, and the resistance voltage is stable. When the grounding terminals 210G and 220G are damaged and no longer connected to the inner partition 24, the circuit is open, and the resistance voltage will be zero or change significantly. Therefore, as long as a significant change in the resistance voltage is detected, the system can remind the user to replace the electrical connector.

[0024] The metal housing 30 includes a top wall 31, a bottom wall 32, and a pair of C-shaped side walls 33. A insertion cavity 34 is formed between the top wall 31, the bottom wall 32, and the side walls 33. The top wall 31 and the bottom wall 32 respectively cover the upper and lower surfaces of the base 11. Both the top wall 31 and the bottom wall 32 are provided with a pair of spring arms 35 protruding toward the insertion cavity 34. Preferably, the metal housing 30 further includes an annular portion 36 protruding rearward from the top wall 31 or the bottom wall 32. The annular portion 36 is integrally connected to the top wall 31 or the bottom wall 32, surrounds the base 11, and engages with the base 11. The annular portion 36 has a pair of rearwardly protruding L-shaped mounting legs 37 at both ends. The L-shaped mounting legs 37 are used to weld and fix the annular portion 36 to a circuit board (not shown).

[0025] The metal cover 40 includes an annular body 41 and a pair of extension plates 42 extending rearward from the body 41. The body 41 is pressed against the surfaces of the top wall 31, bottom wall 32, and side wall 33 of the metal housing 30, and can be fixedly connected to the metal housing 30 by spot welding. The extension plates 42 extend horizontally and cover the upper and lower surfaces of the annular portion 36.

[0026] In summary, the electrical connector of this utility model sets the metal partition 23 into four independent partitions (a pair of inner partitions 24 and a pair of outer partitions 25), and uses the grounding terminals 210G and 220G to bridge and conduct adjacent inner partitions 24 and outer partitions 25 to realize the circuit path. It can monitor whether the grounding terminals 210G and 220G on both sides are damaged, so as to detect the fault of the electrical connector in time and realize quick repair or replacement.
