Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a sintered assembled Ethernet transmission watertight connector. Background Technology

[0002] Watertight connectors, as a type of electrical connector, can withstand the challenges of seawater corrosion and deep-sea pressure in underwater environments, stably meeting the power supply and signal transmission requirements of equipment. The pressure-bearing components within the watertight connector play a crucial role in ensuring the connector's normal operation in underwater environments.

[0003] Existing watertight connectors are generally made by sintering the transmission pressure-bearing component and the housing as a whole. Since glass material needs to be set in the transmission pressure-bearing component to play the role of insulation, sealing and reinforcement and pressure bearing, poor air exhaust is easily caused during the whole sintering process, resulting in many air holes in the glass sintering, which in turn leads to a low qualification rate of the finished connector.

The pin assembly is axially insulated and connected to the pin mounting hole of the base via the glass medium. The glass medium fills the space between the outer wall of the pin assembly and the inner wall of the pin mounting hole of the base and is sintered. The base, the glass medium, and the pin assembly are sequentially connected from the outside to the inside to form a pressure-bearing component with an integral structure. The two ends of the pin assembly extend out of the two side surfaces of the base, one end of which is connected to the socket assembly and the coaxial assembly, and the other end is connected to an external device.

[0006] Furthermore, the interior of the built-in cavity includes a first stepped hole, a second stepped hole, and a third stepped hole that are connected in sequence; The diameters of the first stepped hole, the second stepped hole, and the third stepped hole decrease sequentially.

The base is disposed inside the second stepped hole, and an annular first step is formed therecorresponding to the axial position of the first groove. A first retaining ring is embedded inside the first groove, and the inner ring side of the first retaining ring extends out and abuts against the first step to press the base tightly into the hole of the second step.

[0008] Furthermore, a second annular groove is formed on the inner wall of the second stepped hole. The second groove is located on the side of the first groove near the third stepped hole. A first sealing ring is provided inside the second groove.

[0009] Furthermore, a positioning block is formed on the inner wall of the second stepped hole near one end of the third stepped hole. The base has a positioning groove at the end away from the first step. The positioning block is embedded inside the positioning groove.

[0010] Furthermore, the pin assembly includes a first pin assembly and a second pin assembly. The base has a through mounting hole in the middle along the axial direction; The first pin assembly is mounted inside the mounting hole via the glass medium; The second pin assembly is mounted on the base in the peripheral area of ​​the mounting hole via the glass medium.

[0011] Furthermore, the first pin assembly includes a differential outer conductor pin and a differential inner conductor pin disposed inside the differential outer conductor pin.

[0012] Furthermore, the second pin assembly includes an external pin. The external insertion pin is mounted on the base via the glass medium. The external pins and the differential inner conductor pins are arranged coaxially in a matrix on the base.

[0013] Furthermore, the insulating assembly includes a first insulator and a second insulator.

By designing the transmission pressure-bearing component as a base-supported structure and sintering it independently from the housing, the problem of poor venting caused by integral sintering of the transmission pressure-bearing component and the housing, which leads to numerous sintering pores in the glass dielectric within the transmission pressure-bearing component, is solved. This improves the connector's product yield rate and reduces manufacturing costs. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figures 1 to 4As shown, this utility model provides a sintered assembled Ethernet transmission watertight connector, which may include a housing 100, an insulating component 200, a socket assembly 300, a coaxial assembly 400, and a transmission pressure bearing component 500. The housing 100 has an internal cavity. The insulating component 200 is located at one end of the internal cavity, and the internal cavity extends through both end faces of the housing 100. The socket assembly 300 and the coaxial assembly 400 are located inside the insulating component 200. The socket assembly 300 is used to connect to the transmission pressure bearing component 500 to achieve an electrical connection, transmitting electrical signals or electrical energy. The coaxial assembly 400 mainly functions to construct a four-coaxial transmission structure, connecting the transmission pressure bearing component 500 to transmit multiple signals or achieve different electrical functions, such as simultaneously transmitting high-frequency and low-frequency signals. The transmission pressure bearing component 500 is detachably located at the other end of the internal cavity. The pressure-bearing component 500 may include a base 510, a pin assembly 520, and a glass medium 530. The pressure-bearing component 500 is sealed and connected to the interior of the cavity through the base 510. The pin assembly 520 is axially insulated and connected to the pin mounting hole of the base 510 through the glass medium 530. The glass medium 530 fills the space between the outer wall of the pin assembly 520 and the inner wall of the pin mounting hole of the base 510 and is sintered and formed. The base 510, the glass medium 530, and the pin assembly 520 are connected sequentially from the outside to the inside to form a pressure-bearing component 500 with an integral structure. The two ends of the pin assembly 520 extend out of the two side surfaces of the base 510, one end of which is connected to the socket assembly 300 and the coaxial assembly 400, and the other end is used to connect to external devices.

[0020] Specifically, the sintered assembled Ethernet transmission watertight connector of this utility model has a detachable transmission pressure bearing component 500 inside the housing 100. The transmission pressure bearing component 500 is composed of a base 510, a pin assembly 520 and a glass medium 530. The transmission pressure bearing component 510 is connected to the inside of the housing 100 through the base 510 to achieve a sealed pressure bearing with the housing 100.

[0021] Both the housing 100 and the base 510 are made of metal. The transmission pressure bearing component 500 is set as a structure supported by the base 510 and is sintered independently from the housing 100. This solves the problem of poor air exhaust caused by the integral sintering of the transmission pressure bearing component 500 and the housing 100, which leads to many sintering pores in the glass medium 530 in the transmission pressure bearing component 500. This improves the low product qualification rate of the connector and reduces manufacturing costs.

[0022] In some embodiments, such as Figure 1As shown, the interior of the built-in cavity includes a first stepped hole 110, a second stepped hole 120, and a third stepped hole 130 connected in sequence. The diameters of the first stepped hole 110, the second stepped hole 120, and the third stepped hole 130 decrease sequentially. The first stepped hole 110 is formed as a plug-in portion, the second stepped hole 120 is provided with a transmission pressure bearing member 500, and the third stepped hole 130 is provided with an insulating component 200. One end of the pin assembly 520 extends into the plug-in portion, and the other end extends into the interior of the insulating component 200 to connect to the plug-in assembly 300 and the coaxial assembly 400.

[0023] In other words, a first stepped hole 110, a second stepped hole 120, and a third stepped hole 130 are sequentially connected within the internal cavity of the housing 100, with their diameters decreasing sequentially. Thus, the first stepped hole 110, with the largest diameter, serves as the insertion part, facilitating reliable insertion with the device to be inserted. The second stepped hole 120, with a medium diameter, is used to house the pressure-bearing component 500, effectively achieving limiting and fixing, and ensuring the reliability of the pressure-bearing seal. Furthermore, an insulating component 200 is installed inside the third stepped hole 130, with the smallest diameter, to accommodate the insertion assembly 300 and the coaxial assembly 400. This provides insulation while making the structure more compact. Additionally, since the outer surface of the housing 100 corresponding to the third stepped hole 130 is used for connecting mounting components, and its relatively small outer diameter, the correspondingly smaller diameter of the third stepped hole 130 also ensures the structural strength of this part of the housing 100.

[0024] In some embodiments, such as Figure 1 and Figure 2 As shown, an annular first groove 121 is formed on the inner wall of the second stepped hole 120 near the end of the first stepped hole 110. The base 510 is disposed inside the second stepped hole 120, and an annular first step 511 is formed on it corresponding to the axial position of the first groove 121. A first retaining ring 122 is embedded inside the first groove 121, and the inner ring side of the first retaining ring 122 extends out and abuts against the first step 511 to press the base 510 tightly inside the second stepped hole 120.

[0025] In other words, when the pressure-bearing component 500 is assembled inside the second stepped hole 120, the base 510 is located inside the second stepped hole 120. An annular first groove 121 is formed on the inner wall of the second stepped hole 120 (i.e., near the end of the first stepped hole 110), and a matching annular first step 511 is formed at a corresponding axial position on the base 510. The first step 511 and the first groove 121 mate to form an annular receiving groove for placing the first retaining ring 122. The outer ring side of the first retaining ring 122 abuts against the inside of the first groove 121, and the inner ring side abuts against the first step 511, thereby reliably press-fitting the base 510 inside the second stepped hole 120. Furthermore, the first retaining ring 122 also serves as a seal, isolating the inside of the second stepped hole 120 from the insertion part (i.e., the first stepped hole 110).

[0026] In some embodiments, such as Figure 2 As shown, an annular second groove 123 is also formed on the inner wall of the second stepped hole 120. The second groove 123 is located on the side of the first groove 121 near the third step hole 130, and the first sealing ring 124 is provided inside the second groove 123.

[0027] Therefore, by opening an annular second groove 123 in the middle region of the inner wall of the second stepped hole 120 (that is, the side of the first groove 121 near the third stepped hole 130) and setting a first sealing ring 124 in the second groove 123, the part of the second stepped hole 120 near the third stepped hole 130 is sealed.

[0028] In some embodiments, such as Figure 2 and Figure 4 As shown, a positioning block 125 is formed on the inner side wall of the second step hole 120 near the end of the third step hole 130. The base 510 has a positioning groove 512 on the end away from the first step 511, and the positioning block 125 is embedded in the positioning groove 512.

[0029] This enables the base 510 to be positioned inside the second step hole 110, preventing it from deflecting and improving the reliability of the installation.

[0030] In some embodiments, such as Figure 1 and Figure 4 As shown, the pin assembly 520 includes a first pin assembly and a second pin assembly.

[0031] A through mounting hole 513 is provided in the middle of the base 510 along the axial direction. A first pin assembly is mounted inside the mounting hole 513 through a glass medium 530. A second pin assembly is mounted in the peripheral area of ​​the mounting hole 513 on the base 510 through the glass medium 530.

[0032] As an example, the first pin assembly may include a differential outer conductor pin 521 and at least four differential inner conductor pins 522 disposed inside the differential outer conductor pin 521. The outer wall of the differential outer conductor pin 521 is connected to the mounting hole 513 via a glass medium 530. The four differential inner conductor pins 522 are connected to the inner wall of the differential outer conductor pin 521 via the glass medium 530. The differential outer conductor pin 521 and the four differential inner conductor pins 522 are connected to a coaxial assembly 400 (e.g., a quad coaxial assembly). Thus, the first pin assembly is sintered onto the base 510 through double-layer glass, achieving sealing and pressure resistance between the pins and between the pins and the base 510.

[0033] The second pin assembly may include at least four external pins 523, which are mounted on the base 510 via a glass medium 530. The four external pins 523 and four differential inner conductor pins 522 are arranged coaxially in a matrix on the base 510. The four external pins 523 are connected to the socket assembly 300. The second pin assembly is sintered onto the base 510 using a single layer of glass, achieving sealing and pressure resistance between the pins and the base 510.

[0034] It should be noted that the differential inner conductor pins 522 and outer pins 523 can be six, eight, etc., as long as the coaxial setting is ensured. At the same time, the coaxial assembly 400 can be set as a six-axis assembly, an eight-axis assembly, etc., without specific limitations here.

[0035] In some embodiments, such as Figure 1 As shown, the insulation assembly 200 includes a first insulator 210 and a second insulator 220. The first insulator 210 and the second insulator 220 are interconnected and disposed inside the third stepped hole 130. The first insulator 210 is disposed close to the second stepped hole 120, and its corresponding end is connected to the base 510. This makes the internal structure of the housing 100 more compact and provides good pressure resistance.

[0036] like Figure 3 As shown, a second step 221 is formed on the outer wall of the second insulator 220, and a second retaining ring 222 is provided on the second step 221 to press the second insulator 220 and the first insulator 210 tightly inside the third step hole 130. This makes the installation of the second insulator 220 and the first insulator 210 inside the third step hole 130 more stable and reliable.

[0037] On the inner wall of the third stepped hole 130, near the second retaining ring 222, there is also an annular third groove 131, and a retaining ring 132 is provided in the third groove 131. Specifically, on the one hand, the inner ring side of the retaining ring 132 abuts against the second retaining ring 222 to limit the second retaining ring 222; on the other hand, the retaining ring 132 can seal the inside of the third stepped hole 130.

[0038] In some embodiments, such as Figure 1 As shown, a plurality of second sealing rings 140 are also provided axially at intervals on the outer side wall of the housing 100. This achieves a sealed connection between the connector and the mounting component.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
