Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a contact carrier, a connection assembly, and a connector. Background Technology

[0002] With the continuous development of connector technology, it has been widely used in electrical, optical communication and fluid transmission fields. Traditional connectors typically consist of a housing and a tail sleeve. The tail sleeve is located in the housing and covers the cable inside the housing to protect the cable.

[0003] Currently, mechanical interlocking is commonly used in connectors to position and connect the housing and the tail sleeve. For example, corresponding holes or slots are made on both the housing and the tail sleeve. Then, locating screws or pins are inserted into these pre-designed holes or slots for positioning and connection, thereby fixing the two together.

[0004] However, the above-mentioned connection and positioning method requires high alignment accuracy between the housing and the tail sleeve, making assembly difficult. Utility Model Content

[0005] Therefore, it is necessary to provide a contact carrier, a connection component, and a connector to address the above-mentioned problems.

[0006] The first aspect of this application provides a contact carrier, the contact carrier including a housing, a sleeve, and a locking ring. The housing is used to accommodate a contact component and includes a head end and a tail end disposed opposite to each other. The housing also includes a positioning portion protruding from the inner peripheral wall of the tail end. The sleeve passes through the tail end and abuts against the side of the positioning portion opposite to the head end. The locking ring passes through the tail end and is fitted onto the sleeve. The locking ring is threadedly connected to the inner wall surface of the tail end, and the locking ring abuts against the side of the sleeve opposite to the positioning portion. A glue-receiving groove is formed between the end faces of the locking ring and the tail end, and the glue-receiving groove is filled with a sealing medium.

[0007] In the aforementioned contact carrier, a wire sleeve is inserted at the tail end, with one end of the sleeve abutting against the positioning part, and a locking ring abutting against the side of the wire sleeve facing away from the positioning part. Therefore, the locking ring, in conjunction with the positioning part, can clamp and fix the wire sleeve. The locking ring is threaded to the inner wall of the housing, thus the locking ring can firmly press the wire sleeve against the positioning part to fix it. Compared to conventional technology, this application achieves wire sleeve fixation simply by tightening the locking ring, eliminating the need for the positioning operation in conventional technology, thus simplifying operation and facilitating assembly. Furthermore, a glue-receiving groove is formed between the locking ring and the end face of the tail end, which is filled with a sealing medium. After the sealing medium is filled into the glue-receiving groove, the waterproofness at the tail end is improved, thereby enhancing the overall waterproof performance of the contact carrier. It should be noted that conventional technology provides holes or grooves for grommets or positioning pins to pass through, which restricts sealing and waterproofing. In contrast to conventional technology, this application not only eliminates the need for such holes or grooves but also has a glue-receiving groove for filling with a sealing medium, thus significantly improving sealing and waterproofing.

[0008] In one embodiment, the locking ring has an operating groove located on the end face of the locking ring facing the adhesive groove, and the operating groove is in communication with the adhesive groove. Because the operating groove is in communication with the adhesive groove, configuring the operating groove can increase the amount of adhesive that the contact carrier can hold; furthermore, after the sealing medium extending and distributed within the adhesive groove is formed, it can establish a certain connection between the housing, the sleeve, and the locking ring, improving the relative positional stability of the three components.

[0009] In one embodiment, the inner peripheral wall of the tail end is provided with a first threaded structure, and the operating groove communicates with the area where the first threaded structure is located, for the sealing medium to fill and distribute. That is, the sealing medium can extend and distribute at the first threaded structure, so that after the sealing medium is formed, it can fill the gap between the locking ring and the first threaded structure, thereby further improving the relative positional stability of the locking ring and the housing.

[0010] In one embodiment, the operating groove is radially through-type, connecting the inner and outer ring regions of the locking ring. That is, the sealing medium can extend and distribute at the joint between the locking ring and the sleeve, thus, after forming, the sealing medium can connect within the locking ring and the sleeve, further improving the relative positional stability of the locking ring and the sleeve.

[0011] In one embodiment, there are multiple operating slots, which are evenly distributed at intervals in the circumferential direction of the locking ring.

[0012] In one embodiment, the sleeve includes a first sleeve and a second sleeve. One side of the first sleeve abuts against the positioning part, and the other side is provided with a stepped part and connected to the second sleeve. The locking ring is sleeved on the second sleeve and abuts against the stepped part. The radial thickness of the first sleeve gradually decreases in the direction away from the positioning part.

[0013] In one embodiment, the wire sleeve further includes a third sleeve connected to the end of the second sleeve away from the first sleeve; the contact carrier further includes a wire sheath, which is a flexible body, and the wire sheath is sleeved with the third sleeve and extends outside the housing, and the wire sheath is in communication with the wire sleeve.

[0014] In one embodiment, the contact carrier further includes a tail cap, which is fitted onto the tail end; wherein the outer peripheral wall of the tail end is provided with a second threaded structure, and the tail cap is threadedly engaged with the second threaded structure.

[0015] A second aspect of this application also provides a connection component, the connection component including a contact component and a contact carrier as described above.

[0016] A third aspect of this application also provides a connector, the connector comprising at least one connection component as described above. Attached Figure Description

Detailed Implementation

[0024] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0025] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0029] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0030] One embodiment of this application provides a connector, which includes connecting components. The connecting components can be configured as a plug or a socket as needed. Further, the connector may include two connecting components, i.e., the connector includes at least one connecting component. When the connector includes two connecting components, the two connecting components can be configured as a plug and a socket, respectively.

[0031] In one embodiment, the connector includes, but is not limited to, electrical connectors, fiber optic connectors, pneumatic connectors, and liquid connectors. The embodiments of this application do not limit this and can be configured according to actual needs.

[0032] One embodiment of this application provides a connection assembly including a contact component and a contact carrier. The contact component is disposed within the contact carrier, which mounts and supports the contact component, allowing it to connect with another connection assembly (plug or socket). The contact carrier also provides protection for the contact component. As an example, the connection assembly can be used in a fiber optic connector. In this case, the contact component may include a support structure and a ceramic ferrule. The ceramic ferrule passes through the support structure, with one end aligned with another ceramic ferrule to enable optical signal conduction. The other end of the ceramic ferrule connects to a cable, which extends beyond the contact carrier and connects to an external device. The contact carrier can cover the cable to provide protection and ensure a stable connection between the cable and the contact component. Alternatively, when the connection assembly is used in an electrical connector, the contact component may include an insulator and conductive terminals passing through the insulator, with the conductive terminals connected to the cable.

[0033] See Figures 1 to 3 , Figure 1 This illustration shows an isometric view of a contact carrier provided in one embodiment of this application. Figure 2 for Figure 1 The rear view of the contact carrier shown is as follows. Figure 3 for Figure 2 The diagram shows a cross-sectional view of the contact carrier along line AA. One embodiment of this application provides a contact carrier 10 comprising a housing 100, a cable sleeve 200, and a locking ring 300. The cable sleeve 200 and the locking ring 300 are disposed within the housing 100. The locking ring 300 cooperates with the housing 100 to jointly fix the cable sleeve 200. The cable sleeve 200 can be fitted over the cable connected to the contact component to improve the positional stability of the cable and ensure a stable connection between the contact component and the cable.

[0034] The housing 100 is used to house the contact components. The housing 100 includes a head end 101 and a tail end 102, which are disposed opposite to each other. The housing 100 also includes a positioning portion 110, which protrudes from the inner peripheral wall of the tail end 102. A wire sleeve 200 passes through the tail end 102 and abuts against the side of the positioning portion 110 opposite to the head end 101. A locking ring 300 passes through the tail end 102 and is fitted onto the wire sleeve 200. The locking ring 300 is threadedly connected to the inner wall surface of the tail end 102, and abuts against the side of the wire sleeve 200 opposite to the positioning portion 110.

[0035] In the aforementioned contact carrier 10, a wire sleeve 200 passes through the tail end 102, with one end of the wire sleeve 200 abutting against the positioning part 110, and a locking ring 300 abutting against the side of the wire sleeve 200 facing away from the positioning part 110. Therefore, the locking ring 300 cooperates with the positioning part 110 to clamp and fix the wire sleeve 200. The locking ring 300 is threadedly connected to the inner wall of the housing 100, thus the locking ring 300 can firmly press the wire sleeve 200 against the positioning part 110 to fix the wire sleeve 200. Compared to conventional technology, this application achieves the fixation of the wire sleeve 200 simply by tightening the locking ring 300, eliminating the need for the positioning operation in conventional technology, thus simplifying operation and facilitating assembly. Furthermore, since high-precision alignment between the wire sleeve 200 and the housing 100 is not required, the processing difficulty of the contact carrier 10 is also relatively lower.

[0036] like Figure 4 A sealing groove 103 is formed between the locking ring 300 and the end face of the tail end 102, and the sealing groove 103 is filled with a sealing medium (not shown in the figure, the same below). Thus, after the sealing medium is filled into the sealing groove 103, the waterproofness at the tail end 102 is improved, thereby enhancing the overall waterproof performance of the contact carrier 10. It should be noted that in conventional technologies, holes or grooves are required for the insertion of grommets or locating pins, which restrict the sealing and waterproofing of the connector. Compared to conventional technologies, this application not only eliminates the need for such holes or grooves but also includes a sealing groove 103 for filling with the sealing medium, thus significantly improving both sealing and waterproofing.

[0037] As one example, the sealing medium can be configured as liquid silicone (LSR), epoxy resin, and polyurethane potting compound (PU). Furthermore, when the connector needs to be used in ultra-low temperature environments (such as aerospace), the sealing medium can be configured as fluorosilicone (FLSR), which can withstand temperatures as low as -70°C. Alternatively, when the sealing medium also needs to have conductive properties (e.g., the sealing medium needs to provide EMI shielding), silver / nickel powder can be added to make it a conductive adhesive.

[0038] Please see Figure 3 Regarding the formation of the positioning part 110, as one example, the positioning part 110 can be a positioning structure formed by a portion of the inner wall surface of the housing 100 protruding directly. Alternatively, the positioning part 110 can be a stepped positioning structure resulting from a differentiated inner diameter design within the inner wall surface of the housing 100. In one embodiment, the positioning part 110 can be constructed as a ring structure to improve the stability of the positioning part 110 abutting the positioning end of the sleeve 200.

[0039] Please see Figure 5 Combined Figure 1 and Figure 3In one embodiment, the housing 100 has a first threaded structure 120 and a second threaded structure 130. The first threaded structure 120 is disposed on the inner peripheral wall of the tail end 102 (i.e., the inner peripheral wall of the tail end 102 has the first threaded structure 120), and the first threaded structure 120 can be configured as an internal threaded structure. The second threaded structure 130 is disposed on the outer peripheral wall of the tail end 102 (i.e., the outer peripheral wall of the tail end 102 has the second threaded structure 130), and the second threaded structure 130 can be configured as an external threaded structure. The contact carrier 10 also includes a tail cap 400, which is fitted onto the tail end 102 and threadedly engages with the second threaded structure 130 to relatively enclose the space within the housing 100. Figure 3 It is understandable that the tail cap 400 has a through hole 410, which is connected to the internal cavity of the housing 100. The through hole 410 allows the cable to extend to the outside of the contact carrier 10 so that the cable can be connected to external equipment.

[0040] Please see Figure 6 Combined Figure 4 and Figure 5 In one embodiment, the locking ring 300 has an operating groove 310. Since the locking ring 300 is installed inside the housing 100, it is typically not exposed relative to the housing 100. Therefore, by configuring the operating groove 310, a threaded tightening force can be conveniently provided to the locking ring 300 located within the housing 100 through interaction with the groove wall. That is, the operating groove 310 facilitates control of the locking ring 300's rotation relative to the housing 100, achieving a threaded engagement. Furthermore, the operating groove 310 is located on the end face of the locking ring 300 facing the adhesive groove 103, and the operating groove 310 communicates with the adhesive groove 103. Therefore, the sealing medium in the adhesive groove 103 can also be filled and distributed within the adhesive groove 103. This increases the sealing medium content in the tail end 102, improving sealing performance. Furthermore, the sealing body formed after the sealing medium is molded can restrict the position of the locking ring 300, thereby improving the positional stability of the locking ring 300. For example, the aforementioned seal can absorb vibrations to reduce the likelihood that the locking ring 300 will become loose relative to the housing 100 due to vibrations.

[0041] Please see Figure 4 In one embodiment, the operating groove 310 communicates with the area where the first threaded structure 120 is located, allowing for the distribution of the sealing medium. That is, the sealing medium filled in the adhesive reservoir 103 can extend along the operating groove 310 to the mating point between the first threaded structure 120 and the operating groove 310, further improving the stability of the mating between the locking ring 300 and the first threaded structure 120. In some embodiments, the sealing medium can directly extend from the adhesive reservoir 103 to the first threaded structure 120.

[0042] Please see Figure 6 Combined Figure 4The locking ring 300 includes a third threaded structure 320, which is screwed into the first threaded structure 120. The third threaded structure 320 can be configured as an external thread and can be distributed on the outer peripheral wall of the locking ring 300. The operating groove 310 extends through the third threaded structure 320, thus allowing the sealing medium to extend and fill between the third threaded structure 320 and the first threaded structure 120, improving the tightness of their fit.

[0043] like Figure 3 Similarly, the tail cap 400 includes a fourth threaded structure 420, which is screwed into the second threaded structure 130. The fourth threaded structure 420 can be configured as an internal thread.

[0044] Please see Figure 6 In one embodiment, the operating groove 310 is radially through-hole, connecting the inner and outer ring regions of the locking ring 300. Thus, the sealing medium within the adhesive reservoir 103 can extend through the operating groove 310 to the mating point between the locking ring 300 and the sleeve 200, thereby connecting the sealing medium-formed seal between the locking ring 300 and the sleeve 200, improving their relative positional stability.

[0045] Please see Figure 6 In one embodiment, there are multiple operating grooves 310, which are evenly distributed around the circumference of the locking ring 300. This arrangement facilitates the effective rotation of the locking ring 300 relative to the housing 100 by assembly tools (such as screwdrivers) to achieve a threaded fastening fit. Furthermore, the even distribution of the operating grooves 310 ensures that the sealing medium extending within the operating grooves 310, extending through the operating grooves 310 to the first threaded structure 120, and extending through the operating grooves 310 to the mating point between the locking ring 300 and the sleeve 200 are all evenly distributed, significantly improving the stability of the relative positions of the locking ring 300, the housing 100, and the sleeve 200.

[0046] As one example, the angular span between adjacent operating slots 310 can be 30°, 45°, 60°, 72°, 90°, 120°, and 180°, etc. The number of operating slots 310 can be 2, 3, 4, 5, 6, 8, and 12, etc.

[0047] Please see Figure 4 and Figure 5 In one embodiment, the sleeve 200 includes a first sleeve 210 and a second sleeve 220. One side of the first sleeve 210 abuts against the positioning part 110, and the other side of the first sleeve 210 is provided with a step part 211 and connected to the second sleeve 220. The locking ring 300 is fitted onto the second sleeve 220 and abuts against the step part 211.

[0048] It should be noted that in conventional technology, after the cable sleeve 200 is fitted over the cable, the cable sleeve 200 will be compressed and tightly wrapped around the cable, keeping the cable sleeve 200 fixed to the cable and facilitating the cable sleeve 200 to provide locking force for the cable. Therefore, in this embodiment, the radial thickness H of the first sleeve 210 can be configured to gradually increase in the direction away from the positioning part 110, that is, the stepped part 211 has a relatively larger thickness dimension. This configuration can reduce the deformation of the stepped part 211, so as to form a stable abutment fit with the locking ring 300. On the other hand, the first sleeve 210 has a first wire cavity 212. The radial thickness H of the first sleeve 210 gradually increases in the direction away from the positioning part 110, that is, the first wire cavity 212 is funnel-shaped, which facilitates guiding the cable to be inserted into the first wire cavity 212 and enter the second sleeve 220 along the first wire cavity 212. Furthermore, the second sleeve 220 has a second wire cavity 221, and the flared first wire cavity 212 can guide the wire into the second sleeve 220. The cable inside the second sleeve 220 can extend to the outside of the contact carrier 10 through the through hole 410 of the tail cap 400, so as to facilitate connection to external devices.

[0049] It is understood that the first wire cavity 212 is connected to the inside of the housing 100 so that the cable connected to the contact component installed inside the housing 100 extends into the first wire cavity 212 and extends through the wire sleeve 200 to the outside of the contact carrier 10.

[0050] Please continue reading. Figure 4 In one embodiment, the cable sleeve 200 further includes a third sleeve 230, which is connected to the end of the second sleeve 220 away from the first sleeve 210. The contact carrier 10 also includes a cable sheath (not shown, the same below), which is a flexible body. The cable sheath is fitted onto the third sleeve 230 and extends outside the housing 100, and is in communication with the cable sleeve 200. Thus, the cable can extend outside the contact carrier 10 through the cable sleeve 200 and the cable sheath. The cable sheath is fitted over the cable and has a through hole 410, so the cable sheath can reduce the probability of the cable being damaged due to compression between the cable and the wall of the through hole 410.

[0051] Furthermore, the third sleeve 230 has a third wire cavity 231, and the first wire cavity 212, the second wire cavity 221 and the third wire cavity 231 are connected in sequence, and the third wire cavity 231 is connected to the wire sheath.

[0052] As one example, the cable sheath can be configured as a spring, or it can be configured as a soft rubber sleeve.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
