Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and more particularly to a combined connector. Background Technology

[0002] In connector design for compact electronic devices (such as portable terminals and vehicle controllers), high-density terminal arrangement is the core means to reduce size and improve signal transmission efficiency. In the existing technology, connector cores usually adopt a multi-terminal integrated layout, arranging multiple terminals at close intervals on the core base according to electrical parameter requirements, and fixing them in the core by clips or screws.

[0003] However, this high-density design has significant drawbacks in actual assembly. The tight arrangement of terminals on the ferrule results in limited wiring space between adjacent terminals. Operators need to complete processes such as cable crimping or welding, current testing, etc., within a narrow area of ​​the connector. Insufficient freedom of tool operation can easily lead to crimping or welding failures and damage to the insulation layer, making it inconvenient for operators to install quickly. Utility Model Content

[0004] The purpose of this utility model is to provide a modular connector that allows operators to detachably install the terminals into the ferrule via an insulating base after completing the wiring of the terminals and cables.

[0005] The technical solution adopted by the combined connector disclosed in this utility model is:

[0006] The device includes a male connector, a female connector, and multiple mounting bases. The male connector contains a first insert, and the female connector contains a second insert. Both the first and second inserts have multiple spaced mounting slots, and the bottom of each mounting slot has a through hole. Both the first and second inserts have multiple latches. The mounting base has a receiving slot, and a terminal is fixedly connected to the receiving slot. The terminal protrudes from the mounting base. The receiving slot has a locking assembly. The mounting base has a wiring hole communicating with the receiving slot and a locking groove. The mounting base is placed in the mounting slot, and the terminal passes through the through hole. The latches are locked into adjacent locking grooves. The first insert and the second insert are plugged into each other, and the terminals on the first insert and the second insert are electrically connected.

[0007] As a preferred embodiment, the plurality of mounting slots on the first insert are arranged in two rows on the first insert, the plurality of mounting slots on the second insert are arranged in two rows on the second insert, and the mounting base has two receiving slots.

[0008] As a preferred embodiment, the buckle is close to the mounting groove, and the mounting base has two slots, which are respectively close to the two sides of the mounting base.

[0009] As a preferred embodiment, the locking assembly includes a spring and a lever. The spring is rotatably connected to the receiving groove, one end of the spring contacts the terminal, the lever is rotatably connected to the receiving groove, one end of the lever slides into contact with the other end of the spring, and the other end of the lever protrudes from the mounting base.

[0010] As a preferred embodiment, the terminals on the first ferrule are contact pins, and the terminals on the second ferrule are contact posts.

[0011] As a preferred embodiment, one end of both the contact pin and the contact post extends into a contact portion, the contact portion being fixedly connected to the receiving groove, and the other end of the contact post having a mating hole, the other end of the contact pin being inserted into the mating hole.

[0012] As a preferred embodiment, the first insert has a slot, the through hole on the first insert communicates with the slot, and the second insert is inserted into the slot.

[0013] The beneficial effects of the combined connector disclosed in this utility model are:

[0014] The operator first inserts the cable through the wiring hole into the receiving slot of the mounting base, electrically connecting the cable to the terminal. The locking component then applies a restraining force to the cable, securing it within the receiving slot. After pre-installing cables in multiple mounting bases, the mounting base is placed into the mounting slot, and the terminal is inserted through the through hole. The locking mechanism secures the mounting base within the mounting slot. The detachable design of the mounting base and mounting slot provides more space for cable installation during the assembly stage, solving the problem of difficult cable installation in high-density terminal layouts. Furthermore, if a terminal is damaged, only the corresponding mounting base needs to be replaced, facilitating connector maintenance for the operator. Attached Figure Description

[0040] Furthermore, both the first insert 12 and the second insert 22 are provided with multiple latches 225, which are close to the mounting groove 125.

[0041] Please refer to Figures 2-6 and Figures 8-10 .

[0042] The mounting base 3 has a receiving slot 31. In this embodiment, it is preferred that there are two receiving slots 31, which are located near the two sides of the mounting base 3 respectively, and the two receiving slots 31 correspond to two rows of mounting slots 125. One receiving slot 31 extends out from one end of the mounting base 3, and the other receiving slot 31 extends out from the other end of the mounting base 3. The top of the mounting base 3 has a mounting hole 311, which communicates with the receiving slot 31. The bottom of the mounting base 3 has a wiring hole 312, which communicates with the receiving slot 31. Both sides of the mounting base 3 have notches 313, which communicate with the receiving slot 31.

[0043] Furthermore, a terminal is fixedly connected inside the receiving groove 31, and the terminal passes through the mounting hole 311 and exits the mounting base 3;

[0044] Furthermore, a first connecting post and a second connecting post extend into the receiving slot 31, with the first connecting post near the wiring hole 312 and the second connecting post near the notch 313.

[0045] The receiving groove 31 is provided with a locking assembly 32, which includes a spring piece 321 and a lever 322. In this embodiment, the spring piece 321 is preferably V-shaped, and the middle part of the spring piece 321 is rotatably connected to the first connecting post in the receiving groove 31. One end of the spring piece 321 of the contact pin 36 touches the terminal. In this embodiment, the lever 322 is preferably L-shaped, and the middle part of the lever 322 is rotatably connected to the second connecting post in the receiving groove 31. One end of the lever 322 slides in contact with the other end of the spring piece 321, and the other end of the lever 322 passes through the notch 313 and exits the mounting base 3.

[0046] Furthermore, a groove is provided on the spring 321, and the groove is close to the other end of the spring 321. A locking block extends from one end of the paddle 322, and the locking block slides in contact with the groove. The groove can constrain the rotation range of the paddle 322, and the constraint of the paddle 322 can drive the spring 321 to rotate.

[0047] Rotating the lever 322 towards the outside of the receiving groove 31 reduces the force exerted by one end of the lever 322 on the other end of the spring 321, while also allowing the spring 321 to rotate in the direction of the lever 322. Passing the cable through the wiring hole 312 into the receiving groove 31, the cable extends between one end of the spring 321 and the terminal, establishing an electrical connection between the cable and the terminal. Rotating the lever 322 towards the receiving groove 31 again pushes the other end of the spring 321, causing it to rotate back to its original position. This allows one end of the spring 321 to contact the cable, securing it within the receiving groove 31, facilitating cable connection by the operator.

[0048] The mounting base 3 is provided with two cover plates 33, which cover the two receiving slots 31 respectively. The open design of the receiving slots 31 facilitates the installation of terminals and locking components 32 during the production of this connector.

[0049] The top of the mounting base 3 is provided with a through groove, which is located between two receiving grooves 31; the mounting base 3 is provided with two slots 38, which are located near the two sides of the mounting base 3 and near the top of the mounting base 3.

[0050] The mounting base 3 has multiple positioning posts 34 extending from one end face, and multiple positioning holes 35 opened on the other end face. Both ends of the mounting base 3 have recesses.

[0051] After the cable is connected to the mounting base 3, multiple mounting bases 3 are spliced ​​together in sequence. The mounting base 3 at the beginning is fixed by being inserted into the positioning hole 35 of the adjacent mounting base 3 through the positioning post 34. The corresponding number of mounting bases 3 are spliced ​​according to the total number of mounting slots 125 on the first insert 12 divided by two. The mounting base 3 is placed in the mounting slot 125, the terminal is inserted into the through hole 126, and the buckle 225 is inserted into the adjacent slot 38 to fix it, thus constraining the mounting base 3 in the mounting slot 125.

[0052] The first partition plate 124 of the first insert 12 is engaged in the recesses of two adjacent mounting seats 3 on the first insert 12, and the first positioning plate 123 of the first insert 12 is engaged in the through groove of the mounting seat 3 on the first insert 12, thereby positioning the mounting seat 3 assembled on the first insert 12 and constraining its displacement; the second partition plate 224 of the second insert 22 is engaged in the recesses of two adjacent mounting seats 3 on the second insert 22, and the second positioning plate 223 of the second insert 22 is engaged in the through groove of the mounting seat 3 on the second insert 22, thereby positioning the mounting seat 3 assembled on the second insert 22 and constraining its displacement;

[0053] The detachable design of the mounting base 3 and the mounting slot 125 provides more space for cable installation during the assembly stage, solving the problem of difficult cable installation in high-density terminal layouts. Furthermore, if a terminal is damaged, only the corresponding mounting base 3 needs to be replaced, making it easier for operators to maintain the connector.

[0054] Please refer to Figures 1-11 .

[0055] The terminals on the first insert 12 are contact pins 36, and the terminals on the second insert 22 are contact posts 37. One end of both the contact pin 36 and the contact post 37 extends into a contact portion 361. A positioning groove 314 is provided within the receiving groove 31. The contact portion 361 is inserted into the positioning groove 314 for fixation. A protrusion 362 is provided on one side of the contact portion 361. The protrusion 362 abuts against the edge of the positioning groove 314, constraining the contact portion 361 within the receiving groove 31 and preventing the contact pin 36 and the contact post 37 from disengaging. When the contact spring 321 is dropped, one end of the contact portion 361 touches one side of the contact pin 36; the other end of the contact pin 36 passes through the mounting hole 311 and exits from the mounting base 3 connected to it; the other end of the contact post 37 passes through the mounting hole 311 and exits from the mounting base 3 connected to it; the other end of the contact pin 36 passes through the through hole 126 on the first insert 12 and extends into the slot 121; the other end of the contact post 37 passes through the through hole 126 on the second insert 22; and the other end of the contact post 37 is provided with a mating hole 371.

[0056] When male connector 1 and female connector 2 are connected, the second insert 22 is inserted into the slot 121 of the first insert 12, and the anti-fooling protrusion 222 is engaged in the adjacent anti-fooling groove 122. When male connector 1 and female connector 2 are connected, they play a positioning role. The other end of the contact pin 36 is inserted into the docking hole 371 of the adjacent pair of contact pins 37 for electrical connection. The limiting plate 211 is rotated on the second housing 21 by a certain angle, so that the limiting pin 111 is engaged in the limiting hook, thereby firmly connecting male connector 1 to female connector 2.

[0057] This invention provides a modular connector. The operator first inserts the cable through the wiring hole into the receiving slot of the mounting base, electrically connecting the cable to the terminals. A locking component then applies a restraining force to the cable, fixing it within the receiving slot. After pre-assembling multiple mounting bases with cables, the mounting base is placed into the mounting slot, and the terminals are inserted through the through holes. A snap-fit ​​design secures the mounting base within the mounting slot. The detachable design of the mounting base and mounting slot allows for more space for cable installation during assembly, solving the problem of difficult cable installation in high-density terminal layouts. Furthermore, if a terminal is damaged, only the corresponding mounting base needs to be replaced, facilitating connector maintenance by the operator.
