Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a clamp-type male and female modular connector. Background Technology

[0002] Electrical connectors are highly integrated electrical connectors with a modular design, consisting of multiple standardized connection modules such as signal modules, power modules, filters, and protection modules. These modules can be combined according to specific application requirements to provide flexible connection solutions. Modular connectors are widely used in electronic equipment, communication systems, and other fields due to their high reliability, maintainability, and scalability.

[0003] Modular connectors, as an important component of electrical connectors, are primarily responsible for achieving electrical and mechanical connections between different modules. They typically employ two or more modular connectors connected via a plug-in method, and are positioned and secured through standardized dimensions and positioning devices. This connection method is characterized by its simplicity of operation and reliable connection, ensuring a stable connection between adjacent modules.

[0004] To establish signal connections with adjacent modular connectors, existing modular connectors typically mount both male and female terminals on an insulating housing. Conductivity is achieved through mating with complementary male and female terminals on the adjacent modular connector. However, the separately assembled male and female terminals require separate positioning and installation during assembly, and also need to be manufactured individually, making the overall setup cumbersome and relatively expensive. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a clamp-type male and female modular connector to solve the problem that the manufacturing and installation of the male and female terminals of the existing modular connectors are relatively troublesome.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A clamp-type male-female modular connector includes an insulating shell and a terminal assembly. The terminal assembly includes a female connection part, a male connection part, and a fastening part that connects the male and female connection parts together and is fixed inside the insulating shell. The male and female connection parts extend outside the insulating shell, and two or more modular connectors are mutually inserted and mated. The male connection part of one modular connector electrically contacts the female connection part of another modular connector. The male and female connection parts are integrally formed, allowing for one-time production and improving production efficiency. The fastening part allows the terminal assembly to be directly inserted into the insulating shell along the insertion direction, eliminating the need for multiple installations of the male and female connection parts and simplifying the installation operation.

[0007] Furthermore, the insulating shell has a first surface and a second surface that are relatively distributed. Insertion slots are formed on the insulating shell that pass through the first surface and the second surface respectively. The fitting part is inserted into the insertion slot. The female end connection part protrudes from the fitting part outside the first surface, and the male end connection part protrudes from the fitting part outside the second surface, so that the male end connection part and the female end connection part can be connected and mated with different complementary terminals to achieve electrical connection.

[0008] Furthermore, a first protrusion is formed on one inner wall of the insertion slot, which divides the insertion slot into two insertion cavities; the mating part includes a base plate and two side plates respectively connected to both sides of the base plate and used for insertion into the two insertion cavities, the side plates and the base plate enclose a clearance space adapted to the first protrusion; the male end connection part is connected to one side of the side plates, and the female end connection part is connected to the other side of the side plates, so that the mating part can limit the terminal assembly by cooperating with the first protrusion through the clearance space and the outer wall of the mating part cooperating with the insertion slot.

[0009] Furthermore, the two insertion cavities are spaced apart along the length of the insulating shell, and the substrate is integrally connected to one side of the two side plates along the width of the insulating shell. There is a connecting cavity between the side of the first protrusion and the inner wall of the insertion groove, which respectively connects the two insertion cavities. The substrate is used to be inserted into the connecting cavity and covers the convex surface of the first protrusion to increase the stability of the tight fit between the insertion groove.

[0010] Furthermore, on the inner wall of each of the two insertion cavities away from the connecting cavity, a second protrusion is provided along the width direction of the insulating shell towards the connecting cavity; on the two side plates, a groove is recessed at the position corresponding to the second protrusion for mortise and tenon engagement with the second protrusion, and each groove is provided through the length direction of the insulating shell. The insertion slot extends through a third surface of the insulating shell along the width direction of the insulating shell towards the side away from the second protrusion to form a lateral opening. The fitting part is installed in the insertion cavity from the lateral opening so that the terminal assembly can be inserted into the insertion slot along the width direction of the insulating shell, and the second protrusion restricts the terminal assembly to prevent loosening in the insertion direction.

[0011] Furthermore, barbs are protruding on both sides of the door groove to increase the tightness between the fastening part and the insertion groove.

[0012] Furthermore, the first and second protrusions are flush with the side facing the second surface and form a receiving cavity that penetrates the second surface between them and the insertion slot. The side of the two side plates away from the female end connection extends into the receiving cavity. The substrate has a first solder foot that is bent toward the receiving cavity and extends along the width direction of the insulating shell to the outside of the lateral opening, so that the entire tight fit part is located inside the insulating shell and is convenient for soldering to the circuit board.

[0013] Furthermore, the third surface of the insulating housing is provided with slots on both sides of the lateral opening. The slots penetrate the inner wall of the insertion slot along the length of the insulating housing and connect the lateral opening and the receiving cavity, so as to facilitate the circuit board to be clamped on the insulating housing. After the circuit board is soldered to the first solder joint, the stability and firmness between the circuit board, terminal assembly and insulating housing are improved.

[0014] Furthermore, the female end connection portion includes elastic arms extending from both side plates toward the side away from the male end connection portion and arc-shaped clamping plates connected to the two elastic arms respectively. The two arc-shaped clamping plates each have abutting protrusions on their opposing sides to facilitate clamping the complementary male end.

[0015] Furthermore, the male terminal connection includes an insertion plate that bends from one of the side plates toward the receiving cavity and extends along the insertion direction toward the side away from the female terminal connection. A second solder foot protrudes from the insertion plate and extends in the same direction as the first solder foot. The first solder foot and the second solder foot are respectively disposed on both sides of the slot along the insertion direction to facilitate insertion into the complementary female terminal and soldering to the circuit board.

[0016] The clamp-type male and female modular connector of this utility model has at least the following beneficial effects: by integrating the male end connection part, the female end connection part and the fastening part into one piece, it can be produced in one go without separate production, which greatly improves production efficiency and reduces costs to a certain extent; by setting the fastening part, the female end connection part and the male end connection part are installed on the insulating shell together with the fastening part, which improves installation efficiency and simplifies installation operation.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1 to 6 As shown, the clamp-type male and female modular connector of this utility model includes an insulating housing 1 and a terminal assembly 2. The insulating housing 1 protects the terminal assembly 2, and the terminal assembly 2 is used to cooperate with the complementary terminals on the complementary connector to realize the transmission and switching of electrical signals.

[0028] In this embodiment, the insulating housing 1 has a rectangular parallelepiped structure and is injection molded from plastic. The height direction of the insulating housing 1 is defined as the insertion direction. The two sides of the insulating housing 1 opposite to each other along the insertion direction are defined as the first surface 111 and the second surface 112, respectively. The two sides of the insulating housing 1 opposite to each other along its width direction are defined as the third surface 113 and the fourth surface 114, respectively. To facilitate the installation of the terminal assembly 2, an insertion slot 12 is formed on the insulating housing 1. The insertion slot 12 penetrates the first surface 111 and the second surface 112 along the insertion direction, allowing the terminal assembly 2 to be installed on the insulating housing 1 through the insertion slot 12. Both ends of the terminal assembly 2 extend beyond the first surface 111 and the second surface 112 of the insulating housing 1 along the insertion direction, respectively, so that both ends of the terminal assembly 2 can be used to connect and conduct circuits with complementary male and female terminals, respectively. A connecting protrusion is provided on the fourth surface 114 of the insulating housing 1, and a connecting hole is formed through the connecting protrusion along the insertion direction to facilitate positioning and engagement with the complementary connector.

[0029] In this embodiment, terminal assemblies 2 are arranged in a plurality and spaced apart along the length of the insulating housing 1. The terminal assemblies 2 are all made of conductive material such as copper, and the insertion slots 12 are provided one-to-one with each terminal assembly 2. Each terminal assembly 2 includes a mating part 21 inserted into the insulating housing 1, a female end connection part 22 connected to the mating part 21 and used to clamp the complementary terminal, and a male end connection part 23 connected to the mating part 21 and used to insert into the complementary terminal. The mating part 21, the female end connection part 22 and the male end connection part 23 are all integrally connected and formed. The mating part 21 is located between the male end connection part 23 and the female end connection part 22. The female end connection part 22 extends from the mating part 21 to the outside of the first surface 111 to facilitate mating with the male end connection part 23 of the adjacent module connector. The male end connection part 23 extends from the mating part 21 to the outside of the second surface 112 to facilitate mating with the female end connection part 22 of another adjacent module connector.

[0030] In this embodiment, the fitting part 21 is inserted into the insertion slot 12. The fitting part 21 includes a base plate 211 and two side plates 212 respectively connected to both sides of the base plate 211 and used for insertion into the insertion slot 12. The base plate 211 can be located on either side of the side plates 212 relative to the side plates 212. The width between the base plate 211 and the side plates 212 is slightly larger than the width of the insertion slot 12, so that after the fitting part 21 is inserted into the insertion slot 12, the side plates 212 can abut against the inner wall of the insertion slot 12; or the width between the outer surfaces of the side plates 212 can be adapted to the width of the insertion slot 12 so that it can be inserted into it. To increase the tightness and stability of the connection between the fastening part 21 and the insulating shell 1, a first protrusion 13 is formed on one of the inner walls of the insertion groove 12. The first protrusion 13 divides the insertion groove 12 into two insertion cavities 121. When the two side plates 212 are inserted into the insertion groove 12, they are respectively inserted into the two insertion cavities 121, so that the two sides of each side plate 212 contact the first protrusion 13 and the inner wall of the insertion groove 12, thereby increasing the contact area between the fastening part 21 and the insulating shell 1 and improving the stability. A clearance space adapted to the contour of the first protrusion 13 is formed between the substrate 211 and the two side plates 212. The male end connection 23, the female end connection 22, and the substrate 211 are respectively connected to three different sides of the side plates 212. When the two side plates 212 are respectively inserted into the two insertion cavities 121, the substrate 211 is wrapped around the first protrusion 13 along with the two side plates 212. In this embodiment, the tight-fitting part 21 can be inserted into the insertion groove 12 along the insertion direction, and the substrate 211 can restrict the rotation of the two side plates 212 relative to the first protrusion 13 to a certain extent. In the content defined in this embodiment, the first protrusion 13 is formed from the insertion groove 12 along the width direction of the insulating shell 1 on one side towards the other opposite side, so that the two insertion cavities 121 are spaced apart along the length direction of the insulating shell 1. Correspondingly, the substrate 211 is integrally connected to the side of the two side plates 212 along the width direction of the insulating shell 1. One side of the first protrusion 13 is defined as a convex surface 131. A connecting cavity 122 is formed between the side of the first protrusion 13 with the inner wall of the insertion groove 12, which respectively connects the two insertion cavities 121, so that the first protrusion 13 and the insertion groove 12 form a U-shaped cavity. The corresponding fastening part 21 is also U-shaped. When the two side plates 212 are inserted into the two insertion cavities 121, the base plate 211 is inserted into the connecting cavity 122 so that the first protrusion 13 is located in the clearance space. The base plate 211 covers the convex surface 131 of the first protrusion 13, thereby increasing the contact area and fastening between the fastening part 21 and the insulating shell 1.

[0031] In this embodiment, to facilitate the installation of the fitting part 21, the first protrusion 13 is formed from the side of the insertion groove 12 near the fourth surface 114. The insertion groove 12 penetrates the third surface 113 of the insulating housing 1 along the width direction of the insulating housing 1 to form a lateral opening 14. The fitting part 21 can be installed in the insertion cavity 121 through the lateral opening 14 to reduce friction during installation, thereby making it easier for the fitting part 21 to cover the first protrusion 13 and be inserted into the insertion groove 12. To prevent the tight fitting part 21 from loosening in the insertion direction, a second protrusion 15 is provided on the inner wall of the two insertion cavities 121 away from the connecting cavity 122 (i.e., the inner wall of the insertion cavity 121 near the fourth surface 114) along the width direction of the insulating shell 1 towards the connecting cavity 122. The second protrusion 15 is integrally connected to the inner wall of the first protrusion 13 and the insertion groove 12 along the length direction of the insulating shell 1, respectively, to increase the rigidity of the first protrusion 13 and the second protrusion 15. The two side plates 212 are recessed at positions corresponding to the second protrusions 15, with grooves 213 for mortise and tenon engagement with the second protrusions 15. The second protrusions 15 are rectangular block structures, while the grooves 213 are square or U-shaped notches. Each groove 213 extends along the length of the insulating housing 1 and opens towards the second protrusion 15. This allows the fitting part 21 to be inserted into the insertion slot 12 from the side opening 14 along the width of the insulating housing 1, while the second protrusion 15 passes into the groove 213 along the width, so that the side plates 212 are mortised and tenoned onto the second protrusions 15. The second protrusions 15 restrict the movement of the side plates 212 in the insertion direction, thereby improving the firmness and stability between the terminal assembly 2 and the insulating housing 1, ensuring the safety of the connector. To further enhance the firmness between the second protrusions 15 and the side plates 212, barbs 2131 or protruding teeth are provided on opposite sides of the grooves 213.

[0032] To prevent the terminal assembly 2 from detaching from the insertion slot 12 in the width direction after it is installed in the insulating housing 1 through the side opening 14, slots 16 are provided on the third surface 113 of the insulating housing 1 on both sides of the side opening 14. The slots 16 are square or U-shaped and extend through the third surface 113 in the width direction. The slots 16 also extend through the inner wall of the insertion slot 12 in the length direction of the insulating housing 1 to connect with the side opening 14. The circuit board a is inserted into each slot 16 in the width direction to block one side of the connecting cavity 122 of the insertion slot 12, preventing the fastening part 21 from loosening in the width direction. In the length direction, it is restricted by the first protrusion 13 and the insertion slot 12. Therefore, the insertion slot 12 restricts the movement of the terminal assembly 2 in all directions to ensure the stability of the terminal assembly 2.

[0033] In this embodiment, the first protrusion 13 and the second protrusion 15 are flush with the side facing the second surface 112 and form a receiving cavity 123 that penetrates the second surface 112 between them and the insertion slot 12. The two side plates 212 have a square sheet structure and extend into the receiving cavity 123 on the side away from the female end connection portion 22. The slot 16 communicates with the receiving cavity 123. A first solder foot 241 is formed on the substrate 211 and extends along the width direction of the insulating shell 1 to the outside of the lateral opening 14 after being bent toward the receiving cavity 123. The first solder foot 241 is located on the side of the slot 16 near the first surface 111 for soldering to one side of the circuit board a when the circuit board a is inserted into the slot 16. The first solder foot 241 corresponds to the electrical connection between the female end connection portion 22 and the circuit board a.

[0034] In this embodiment, the female end connection portion 22 includes elastic arms 221 extending towards each other from the two side plates 212 toward the side away from the male end connection portion 23, and arc-shaped clamping plates 222 connected to the two elastic arms 221 respectively. The arc-shaped clamping plates 222 are located at the end of the elastic arm 221 away from the side plate 212. The two ends of the arc-shaped clamping plates 222 are distributed on both sides of the elastic arm 221 along the width direction of the insulating shell 1, and the ends of the two arc-shaped clamping plates 222 gradually widen toward the side away from the elastic arm 221. The middle parts of the two arc-shaped clamping plates 222 protrude towards each other and approach each other, so that the complementary male terminal can be squeezed into the gap between the two arc-shaped clamping plates 222. Each of the two arc-shaped clamping plates 222 has abutting protrusions 223 on the opposite side to increase the clamping force of the arc-shaped clamping plates 222 on the complementary male terminal.

[0035] In this embodiment, the male connector 23 includes an insertion plate that bends from one side plate 212 toward the receiving cavity 123 and extends along the insertion direction toward the side away from the female connector 22. The insertion plate is square so that it is spaced apart from the inner wall of the receiving cavity 123. A second solder foot 242 extending in the same direction as the first solder foot 241 is protruding on the insertion plate. The second solder foot 242 is formed on one side of the insertion plate corresponding to the third surface 113 of the insulating housing 1. The second solder foot 242 is located on one side of the slot 16 near the second surface 112 so that the first solder foot 241 and the second solder foot 242 are respectively disposed on both sides of the slot 16 along the insertion direction for welding to the other side of the circuit board a when the circuit board a is inserted into the slot 16. The second solder foot 242 corresponds to the connection between the male connector 23 and the circuit board a.

[0036] Compared with the prior art, the clamp-type male and female modular connector of this utility model has the following advantages: the male end connection part 23 and the female end connection part 22 are integrally formed, which reduces production costs and manufacturing difficulty; through the cooperation of the tight-fitting part 21, the circuit board a and the insertion slot 12, the movement of the terminal assembly 2 is restricted in all directions, making the connection between the terminal assembly 2 and the insulating shell 1 more stable and improving the safety of use; by increasing the contact area with the tight-fitting part 21, the fastening is improved and the terminal assembly 2 is prevented from shaking.
