[0005] In the prior art cable connector, a row of holes is generally provided on the housing, so that each terminal in the terminal row extends out from each hole in the row of holes. Since the terminal has a certain length, the root of the terminal is fixed inside the cable connector and connected to the cable, and the extended end of the terminal extends out of the row of holes for plugging with the wiring socket. If one of these terminals does not have an opening perpendicular to the cable connector, it will affect the electrical connection with the wiring socket. Summary of the invention

[0006] The purpose of the embodiments of the present application is to provide a cable connector and a cable connection assembly to solve the technical problem that the installation structure of the terminal row on the cable connector in the prior art cannot ensure that each terminal in the terminal row can extend vertically from each port, thus affecting the smooth plugging with the socket.

[0053] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0055] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0056] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0057] Common PLC cable connection components generally include cable connectors and wiring sockets, and the wiring sockets are set on PLC equipment. The cable is connected to the cable connector, and the cable connector is provided with a terminal row and a row of holes for each terminal in the terminal row to extend out, so that when the cable connector and the wiring socket are plugged into each other, each terminal in the terminal row can pass through the row of holes and be electrically connected to the plug-in part on the wiring socket.

[0058] In practical applications, since the terminal has a certain length, the terminal is arranged inside the cable connector, the root of the terminal is used to connect with the cable in the cable connector, and the extended end of the terminal extends out of the row hole. The terminal row is composed of multiple terminals arranged side by side. If one of these terminals is not perpendicular to the hole of the cable connector, it will cause the position of the plug-in part on the wiring socket to not correspond, thereby affecting the plug-in with the wiring socket.

[0059] Therefore, the fixing structure of the terminal inside the cable connector is particularly important. It is necessary to make each terminal in the terminal row perpendicular to the port of the cable connector to ensure smooth plugging with the wiring socket.

[0060] To this end, the embodiments of the present application provide a new type of cable connector and cable connection assembly, which can effectively solve the technical problem that the installation structure of the terminal row inside the traditional cable connector cannot ensure that each terminal in the terminal row can extend vertically from each port, affecting the smooth connection with the socket. It is now described in detail.

[0061] Please also read Figure 1 , Figure 2 and Figure 3 A cable connection assembly includes a cable connector 100 and a socket 200 of the present application, and a cable 300 is connected to the cable connector. The cable connector 100 includes a housing 1 and a terminal block 2 arranged inside the housing 1.

[0062] Please also read Figure 1 , Figure 3 and Figure 4 The terminal row 2 includes a plurality of terminals 20, each of which includes a fixed end 21, a connecting rib 22, and a connecting end 23 connected in sequence, and the fixed end 21 and the connecting end 23 are connected to the two ends of the connecting rib 22. The fixed end 21 is used to connect to the cable head inside the cable connector 100, and the connecting end 23 is used to electrically connect to the plug-in part on the socket 200.

[0063] The connecting ribs 22 of each terminal 20 are connected sideways between the fixed end 21 and the connecting end 23 on the same side, so that a side opening 24 opposite to the connecting ribs 22 is formed on the other side between the fixed end 21 and the connecting end 23. Figure 4As shown, the terminal 20 is connected between the fixed end 21 and the connecting end 23 and is disposed close to the left side of the fixed end 21 and the connecting end 23 so that the right side of the fixed end 21 and the connecting end 23 forms a side opening 24 opposite to the connecting rib 22 .

[0064] Please also read Figure 5 and Figure 6 A row of terminal fixing members 3 are arranged inside the housing 1, and each terminal fixing member 3 faces the same direction and is arranged at intervals. Each terminal fixing member 3 has a first side and a second side arranged opposite to each other, and a terminal buckle 31 and protrusions 32 located on both sides of the terminal buckle 31 are arranged on the first side, and a limiting plane 33 is arranged on the second side of the terminal fixing member 3. Among them, the terminal buckle 31 can be preferably a U-shaped extension to maximize the reduction of materials, which is conducive to reducing the overall weight of the cable connector 100.

[0065] Specifically, Figure 6 As shown, the left side (first side) of the terminal fixing member 3 includes an upper protrusion 32a, a terminal buckle 31 and a lower protrusion 32b from top to bottom, which are arranged at intervals and correspond to the fixed end 21, the side opening 24 and the connecting end 23 on the terminal 20 respectively. The right side (second side) of the terminal fixing member 3 is a limiting plane 33. These terminal fixing members 3 are arranged in the same direction and at intervals in the housing 1, and a receiving compartment 30 for arranging the terminal 20 is formed between adjacent terminal fixing members 3.

[0066] Please also read Figure 6 , Figure 7 and Figure 8 The terminal 20 in the terminal row 2 is arranged between two adjacent terminal fixing members 3, and the fixing end 21 and the connecting end 23 of the terminal 20 are respectively against the protrusion 32 on one side of the terminal fixing member 3. Figure 8 As shown, the right side of the fixing end 21 abuts against the upper protrusion 32a, and the right side of the connecting end 23 abuts against the lower protrusion 32b.

[0067] Please combine Figure 4 and Figure 8 As shown, the terminal buckle 31 on the terminal fixing member 3 is embedded in the side opening 24 of the terminal 20, and is buckled between the fixing end 21 and the connecting end 23 of the terminal 20, so as to restrict the terminal 20 in the receiving compartment 30. The side of the terminal buckle 31 and the limiting plane 33 on the terminal fixing member 3 on the other side respectively position the connecting rib 22 from both sides, so as to fix the terminal 20 in the receiving compartment 30.

[0068] Compared with the prior art, the cable connector 100 provided in the embodiment of the present application improves the internal terminal 20 fixing structure, and a terminal fixing member 3 for fixing the terminal row 2 is provided in the housing 1, and a receiving compartment 30 for fixing the terminal 20 is formed between adjacent terminal fixing members 3.

[0069] In order to ensure that each terminal 20 in the terminal row 2 is disposed in each receiving compartment 30 and can be disposed vertically, so that each terminal 20 can vertically extend from a port on the cable connector 100, the structure of the terminal 20 and the terminal fixing member 3 is redesigned.

[0070] like Figure 4 As shown, each terminal 20 in the terminal row 2 includes a fixed end 21, a connecting rib 22 and a connecting end 23 that are integrally connected. The connecting rib 22 is connected sideways between the same side of the fixed end 21 and the connecting end 23 so that a side opening 24 that is aligned with the connecting rib 22 is formed on the other side of the fixed end 21 and the connecting end 23.

[0071] In conjunction with Figure 8 As shown, a terminal buckle 31 and a protrusion 32 corresponding to the positions of the fixed end 21 and the connecting end 23 are provided on one side of the terminal fixing member 3. The terminal buckle 31 can be inserted into the side opening 24 of the terminal 20 and buckled between the fixed end 21 and the connecting end 23. The side of the terminal buckle 31 and the limiting plane 33 on another adjacent terminal fixing member 3 together position the connecting rib 22.

[0072] It can be seen that the terminal 20 is fixed by the terminal buckle 31 as a whole, the connecting rib 22 on one side of the terminal 20 is limited between the adjacent limiting plane 33 and the side of the terminal buckle 31, and the other side of the terminal 20 is fixed by two protrusions 32 against the fixed end 21 and the connecting end 23, respectively, so as to prevent the terminal 20 from swinging in the receiving compartment 30. In this way, each terminal 20 in the terminal row 2 can be vertically arranged in each receiving compartment 30, so that each terminal 20 can be vertically extended from the port on the cable connector 100 and smoothly plugged into the plug-in part on the socket 200, effectively solving the problem that the installation structure of the terminal row 2 inside the traditional cable connector 100 cannot allow each terminal 20 to be vertically extended from the port, thereby ensuring the wiring accuracy between the cable connector 100 and the socket 200.

[0073] For the structure of the terminal fixing member 3, in one embodiment of the present application, please refer to Figure 6 and Fig. 9 The side of the terminal buckle 31 is provided with a protrusion 311 for pressing against the connecting rib 22. The protrusion 311 is used to press the connecting rib 22 between the limiting plane 33 and the side of the terminal buckle 31, thereby increasing the clamping force on the connecting rib 22 and improving the fixing effect of the connecting rib 22.

[0074] Among them, a guide slope 312 is also provided on the protrusion 311 on the side of the terminal buckle 31, so that when installing the terminal 20, the connecting rib 22 on the terminal 20 can slide along the guide slope 312 into between the limiting plane 33 and the side of the terminal buckle 31, effectively improving the installation efficiency.

[0075] In another embodiment of the present application, please refer to Figure 6 and Fig. 9 The terminal fixing member 3 is also provided with a convex rib 331 located on the limiting plane 33 , and the convex rib 331 is used to abut against the terminal 20 .

[0076] In this embodiment, at least two ribs 331 are provided on the limiting plane 33, wherein one rib 331a abuts against the connecting rib 22, and the other rib 331b abuts against the connecting end 23, thereby increasing the positioning points and clamping points against the terminal 20, which is beneficial to improving the positioning effect of the terminal 20.

[0077] For the structure of the terminal 20, in one embodiment of the present application, please refer to Figure 4 The connecting rib 22 on the terminal 20 is preferably a bent sheet, and the connecting rib 22 is bent and connected between the fixed end 21 and the connecting end 23 of the terminal 20.

[0078] Specifically, the connecting rib 22 of the terminal 20 extends from one side of the connecting end 23 to the fixed end 21, and is bent and connected to the other side of the fixed end 21. Figure 4 As shown, one end of the connecting rib 22 is connected to the left side of the connecting end 23, and the connecting rib 22 extends from the connecting end 23 to the same side of the fixed end 21. Then, the connecting rib 22 bends and extends to the right side of the fixed end 21 and is connected to the right side of the fixed end 21.

[0079] In this way, a local bending structure is formed on the connecting rib 22 of the terminal 20, which is beneficial to improving the structural strength of the connecting rib 22; and the two ends of the connecting rib 22 are staggeredly connected to different sides of the fixed end 21 and the connecting end 23, thereby forming a terminal 20 structure with a central notch. This is beneficial to improving the overall structural strength of the terminal 20, preventing the terminal 20 from being easily deformed, affecting the installation compatibility with the terminal fixing member 3, and extending the service life.

[0080] In the embodiments of this application, please refer to Figure 4 and Fig.10 The connecting end 23 on the terminal 20 includes a pair of spring clips 230 extending in parallel, and the distance between the pair of spring clips 230 gradually decreases toward the extending end thereof.

[0081] In this embodiment, if Fig.10As shown, the pair of spring clips 230 include a connecting piece 231 connected to the connecting rib 22 at one side and an elastic piece 232 extending outward from the connecting piece 231. The pair of connecting pieces 231 are respectively connected to the connecting rib 22 to form a frame structure. The extending ends of the pair of elastic pieces 232 are each provided with a convex portion 233 and a flange 234. The two convex portions 233 on the pair of elastic pieces 232 are close to each other for clamping the inserted object. The two flanges 234 on the pair of elastic pieces 232 are respectively extended outward to form a flared opening, so that the inserted object can be inserted between the two convex portions 233 along the flared opening, thereby improving the smoothness and stability of the plugging operation with the socket 200.

[0082] In the examples of this application, please refer to Fig.10 The fixed end 21 of the terminal 20 includes a welding piece 211 and ribs 212 on both sides of the welding piece 211, and the connecting rib 22 of the terminal 20 is connected to the rib 212 on either side. In this embodiment, the connecting rib 22 is connected to the rib 212 on a different side from the connecting end 23.

[0083] The welding sheet 211 is preferably an arc-shaped sheet with a depression in the middle, so that the solder can be concentrated along the arc-shaped surface of the welding sheet 211, which is beneficial to improving the welding efficiency.

[0084] Preferably, the fixed end 21, the connecting rib 22 and the connecting end 23 of the terminal 20 are connected as one body, which helps to reduce the difficulty of production, ensure the overall structural strength of the terminal 20, avoid deformation, and extend the service life.

[0085] For the structure on the housing 1, in one embodiment of the present application, please refer to Fig.11 The shell 1 is provided with a wire hole 10 for the cable 300 to extend into, and the inside of the shell 1 is also provided with a clamp seat 11 for fixing the access cable 300. The clamp seat 11 is connected to the wire hole 10, and the cable 300 can extend into the shell 1 from the wire hole 10 and be fixed on the clamp seat 11.

[0086] The clamp seat 11 is provided with a frame 111 for clamping the cable 300, and the frame 111 is composed of intersecting ribs. The frame 111 is used to clamp the cable portion extending into the clamp seat 11, which is beneficial to prevent the cable 300 from loosening and improve the fixing effect of the cable 300.

[0087] Preferably, please also refer to Fig.11 and Fig.12 The frame 111 is also provided with protruding nails 112, which can be preferably arranged at the intersection of the ribs of the frame 111 to improve the structural strength. The protruding nails 112 on the frame 111 are used to pierce the cable 300 located inside the housing 1, further improving the fixing effect of the cable 300.

[0088] In the embodiments of this application, please refer to Fig.12 and Fig.13 The housing 1 includes a first half shell 12 and a second half shell 13 that can be assembled with each other. The first half shell 12 is provided with the above-mentioned terminal fixing member 3, and the second half shell 13 is provided with two rows of top ribs 131 and top grids 132. When the terminals 20 in the terminal row 2 are respectively arranged in the receiving grids 30, the top ribs 131 correspond to the positions of the fixed ends 21 of the terminals 20 one by one, and stop on the fixed ends 21. The top grids 132 correspond to the positions of the connecting ribs 22 and the connecting ends 23 of the terminals 20, and stop on the connecting ribs 22 and the connecting ends 23 at the same time. In this way, multiple directions are added to position the terminals 20, effectively improving the concentricity of the terminals 20 arranged in the receiving grids 30.
