Description

Technical Field

[0001] This utility model relates to a connector and belongs to the field of connector technology. Background Technology

[0002] Electrical devices can transmit power and signals via cables, but cable connections are easily constrained by space limitations and the cable's own bending radius. This means that cables located outside the equipment enclosure can only extend along its axis, making it difficult to achieve 90° cable connections and limiting their adaptability to various enclosure types. To achieve 90° connections between cables and equipment, connectors are typically used as intermediate adapters, but these are often complex in structure and require cumbersome wiring.

[0003] In view of this, it is indeed necessary to improve the existing connectors to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a connector that can achieve 90° wiring even when space is limited, and that is also easy to wire and occupies little space.

[0005] To achieve the above objectives, this utility model provides a connector, mounted on a device housing, comprising:

[0006] The base has a first and a second receiving cavity that are interconnected and perpendicular to each other, and the first receiving cavity is in communication with the interior of the device housing;

[0007] A terminal block is assembled in the first receiving cavity and partially obscures the second receiving cavity. The terminal block is provided with interconnected and perpendicular connecting holes and fixing holes.

[0008] The cable passes through the second receiving cavity and extends into the connection hole to be electrically connected to the terminal block;

[0009] A locking element passes through the fixing hole and into the connecting hole to abut against the cable, thereby fixing the cable in the connecting hole.

[0010] Optionally, the central axis of the fixing hole coincides with the central axis of the first receiving cavity, and the central axis of the connecting hole coincides with the central axis of the second receiving cavity.

[0011] Optionally, the base is further provided with an installation port communicating with the first receiving cavity, the wiring terminal is inserted into the first receiving cavity through the installation port and abuts against the inner wall surface of the first receiving cavity; the fixing hole is exposed to the installation port so that the locking member is inserted into the fixing hole.

[0012] Optionally, the locking element is a wire locking screw.

[0014] Optionally, multiple first receiving cavities and multiple second receiving cavities are provided respectively, and the multiple first receiving cavities are not connected to each other, nor are the multiple second receiving cavities connected to each other.

[0015] Optionally, the connector further includes a grounding terminal located next to the wiring terminal. The grounding terminal is housed within the first receiving cavity, with one end connected to the cable and the other end connected to the device housing to achieve grounding.

[0016] Optionally, the grounding terminal has interconnected and perpendicular through holes and vias, and the cable extends into the through holes and is connected to the grounding terminal through the locking member.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figures 1-9 As shown, this utility model discloses a connector 100, which is installed on a device housing (not shown). The connector 100 enables 90° wiring on the device housing and is compatible with a wider range of housing types. The connector 100 includes a base 1, a terminal block 2 assembled within the base 1, a cable (not shown) partially housed within the base 1 and electrically connected to the terminal block 2, and a locking member 3 for securing the cable and the terminal block 2. The cable is located on the outside of the device housing. The cable is perpendicular to the terminal block 2, allowing for 90° wiring.

[0031] Specifically, the base 1 has a first receiving cavity 11 and a second receiving cavity 12 that are interconnected and perpendicular to each other. The first receiving cavity 11 is in communication with the interior of the device housing. The terminal block 2 is assembled in the first receiving cavity 11 and partially obscures the second receiving cavity 12. The terminal block 2 has a connecting hole 21 and a fixing hole 22 that are interconnected and perpendicular to each other. The cable passes through the second receiving cavity 12 and extends into the connecting hole 21 to be electrically connected to the terminal block 2. The locking member 3 passes through the fixing hole 22 and abuts against the cable in the connecting hole 21 to fix the cable in the connecting hole 21. This utility model, by providing a first receiving cavity 11 and a second receiving cavity 12 that are perpendicular to each other in the base 1, and by providing a connecting hole 21 and a fixing hole 22 that are perpendicular to each other in the terminal block 2, enables 90° wiring of the connector 100, and the wiring of the connector 100 is convenient.

[0032] In this embodiment, the terminal block 2 extends along the first receiving cavity 11. One end of the terminal block 2 facing the inside of the device housing connects to a cable inside the device housing for power or signal transmission. The connection hole 21 and the fixing hole 22 are located at the end of the terminal block 2 away from the device housing. The central axis of the fixing hole 22 coincides with the central axis of the first receiving cavity 11, and the central axis of the connection hole 21 coincides with the central axis of the second receiving cavity 12, so that the cable can pass through the connection hole 21, and the locking member 3 securely connects the cable and the terminal block 2.

[0033] like Figures 3-5 As shown, the outer peripheral wall of the terminal 2 is provided with an axially extending groove 23, and the inner peripheral wall of the first receiving cavity 11 is provided with a boss 111. The boss 111 protrudes into the groove 23 to restrict the radial rotation of the terminal 2. The first receiving cavity 11 is also provided with a limiting part 112 surrounding the outer periphery of the terminal 2. The limiting part 112 is funnel-shaped and gradually decreases in size along the direction of the first receiving cavity 11 towards the device housing to restrict the axial movement of the terminal 2.

[0034] In this embodiment, multiple terminals 2 are provided, arranged side-by-side and spaced apart. Multiple first receiving cavities 11 and multiple second receiving cavities 12 are respectively provided, and the multiple first receiving cavities 11 are not connected to each other, nor are the multiple second receiving cavities 12 connected to each other. That is, the first receiving cavities 11 and the second receiving cavities 12 form a one-to-one correspondence for the installation space 10, and the multiple installation spaces 10 are spaced apart, ensuring that the multiple terminals 2 do not contact each other, thus guaranteeing stable power or signal transmission.

[0035] like Figure 4 As shown, the base 1 also has a mounting port 13 communicating with the first receiving cavity 11. The terminal 2 is inserted into the first receiving cavity 11 through the mounting port 13 and abuts against the inner wall of the first receiving cavity 11, limiting the position of the terminal 2. The fixing hole 22 is exposed in the mounting port 13 so that the locking member 3 can be inserted into the fixing hole 22. The locking member 3 is preferably a wire-locking screw, and the locking member 3 is threadedly connected to the fixing hole 22. The length of the locking member 3 extending into the connecting hole 21 can be adjusted by using a wrench or similar tool, thereby adjusting the distance between the locking member 3 and the cable. The locking member 3 presses against the cable to fix the cable.

[0036] like Figure 2 and Figure 6As shown, the connector 100 also includes a cover plate 4 installed at the mounting port 13, used to cover the wiring terminal 2 and the locking member 3 inside the base 1, and to restrict the axial movement of the wiring terminal. The cover plate 4 has a protruding fastener 41, and the base 1 has a corresponding fastening groove 14. The fastener 41 engages with the fastening groove 14 to connect the cover plate 4 and the base 1. In this embodiment, two fasteners 41 are provided, located on the same side of the cover plate 4.

[0037] The fastener 41 includes a first extension 411 extending outward from the edge of the cover plate 4, and a second extension 412 extending from the end of the first extension 411 toward the base 1. The first extension 411 and the second extension 412 are preferably arranged vertically. A protrusion 413 is provided on the second extension 412. The fastening groove 14 is located outside the mounting opening 13 and is not in communication with the mounting opening 13. A card interface 141 is provided on the side wall of the fastening groove 14 opposite to the mounting opening 13, and the card interface 141 is through-hole.

[0038] During the process of the fastener 41 being engaged with the slot 14, the second extension 412 extends into the slot 14, and the protrusion 413 extends into the interface 141, thereby securing the cover plate 4 and the base 1 together. After the fastener 41 is engaged with the slot 14, a wrench or similar tool is needed to move the protrusion 413 out of the interface 141 to disengage the fastener 41 from the slot 14, allowing the cover plate 4 to be removed from the base 1. This ensures a secure connection between the cover plate 4 and the base 1, preventing accidental detachment of the cover plate 4 and the resulting connection interruption, which could pose a significant safety hazard.

[0039] The connector 100 further includes a sealing ring 5 and a plug 6. The sealing ring 5 is located between the cover plate 4 and the base 1, and the sealing ring 5 is preferably an O-ring. The plug 6 is located inside the second receiving cavity 12, and the cable passes through the plug 6. A sealing gasket (unlabeled) is also provided between the connector 100 and the device housing. The sealing ring 5, the plug 6, and the sealing gasket all serve to seal and waterproof the device.

[0040] Preferably, the base 1 also includes a circuit board (not shown) for signal integration. The circuit board is located on one side of the plurality of terminals 2, preferably below them. All of the terminals 2 are electrically connected to the circuit board via wires. One end of each wire is soldered to the circuit board, and the other end is connected to a terminal 2. The method of connecting the other end of the wire to the terminal 2 is the same as the method of connecting the cable to the terminal 2 described above.

[0041] like Figure 5 As shown, the terminal block 2 is further provided with a first hole 24 and a second hole 25 that are interconnected and perpendicularly arranged. The first hole 24 and the second hole 25 are located on the side of the connection hole 21 near the device housing. The central axis of the first hole 24 is parallel to the central axis of the connection hole 21, and the central axis of the second hole 25 coincides with the central axis of the fixing hole 22. The second hole 25 communicates with the connection hole 21. The wire extends into the first hole 24 and is fixed in the first hole 24 by a fastener (not shown) located in the second hole 25, thereby realizing the electrical connection between the terminal block and the circuit board.

[0042] like Figures 7-9 The image shows a second embodiment of the connector 100 of this utility model. In this embodiment, the connector 100 includes all the structures of the first embodiment, plus a grounding terminal 7 located beside the wiring terminal 2. The grounding terminal 7 is housed within the first receiving cavity 11, with one end connected to the cable and the other end connected to the device housing to achieve grounding. Preferably, the structure of the grounding terminal 7 is substantially the same as that of the wiring terminal 2. The grounding terminal 7 has interconnected and perpendicular through holes 71 and 72. The cable extends into the through hole 71 and is connected to the grounding terminal 7 through the locking member 3. Here, the cable is essentially a grounding wire, which can be directly connected to the device housing through the grounding terminal 7 to reduce costs and save operating time.

[0043] Specifically, the device housing has a through-hole for mounting the connector 100 and a grounding portion connected to the through-hole. The grounding portion is formed by the device housing extending into the through-hole. The grounding portion is correspondingly provided with the grounding terminal 7. The end of the grounding terminal 7 near the device housing has a locking hole 73, and the grounding portion has a corresponding mating hole that aligns with the locking hole 73. By passing a screw through the locking hole and the mating hole, the grounding wire is connected to the device housing, which is convenient to operate and provides reliable grounding.

[0044] In summary, the connector 100 of this invention provides a first and second receiving cavity 11 and 12 that are interconnected and perpendicular to each other on the base 1, and a connecting hole 21 and a fixing hole 22 that are interconnected and perpendicular to each other on the terminal block 2. Thus, when the terminal block 2 is assembled in the first receiving cavity 11 and partially obscures the second receiving cavity 12, the cable can pass through the second receiving cavity 12 and extend into the connecting hole 21 to electrically connect with the terminal block 2. Then, the locking member 3 passes through the fixing hole 22 into the connecting hole 21 and abuts against the cable, fixing the cable within the connecting hole 21. Compared to the prior art, the connector 100 of this invention can achieve 90° wiring even in situations with limited space, and the connector 100 is convenient to wire and occupies little space.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
