Detailed Implementation

[0019] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The inventors discovered through analysis of existing technologies that the terminals of existing connectors are usually directly connected to the plastic shell through a simple snap-fit ​​structure. However, under continuous high vibration conditions, the plastic material is prone to plastic deformation and fatigue damage, and the metal terminals will also undergo reciprocating deformation under alternating stress, resulting in metal fatigue. This causes the snap-fit ​​structure to loosen or even break, leading to the terminal falling off and resulting in insufficient connection reliability.

[0021] Reference Figures 1 to 8 This illustration shows a terminal limiting connector provided in an embodiment of the present application, comprising: a housing 10, a locking member 20, and at least two conductive terminals 30; The mating side of the outer casing 10 is provided with a locking latching part 11; the wiring side of the outer casing 10 is provided with at least two terminal insertion slots 12; the terminal insertion slots 12 correspond one-to-one with the conductive terminals 30; The conductive terminal 30 is provided with a terminal latching part 301, and the terminal insertion groove 12 is provided with a terminal latching part 101 corresponding to the terminal latching part 301; the terminal latching part 101 is provided with a movable cavity 102 for elastic deformation; the terminal latching part 301 is engaged and connected with the corresponding terminal latching part 101. The locking member 20 is provided with a terminal limiting part 21 corresponding to the movable cavity 102, and a locking latching part 201 corresponding to the locking latching part 11; When the locking member 20 is in the locked state, the locking latch part 201 and the locking latching part 11 are engaged and connected; the terminal limiting part 21 is embedded in the movable cavity 102, so that the terminal latching part 101 and the terminal latching part 301 are locked together, and the locking latching part 11 and the locking latching part 201 are locked together.

[0022] In the embodiments of this application, addressing the problem that terminals of existing connectors are prone to detachment under high vibration environments, leading to insufficient connection reliability, this application provides a solution using a locking member 20. Specifically, a terminal limiting connector includes: a housing 10, a locking member 20, and at least two conductive terminals 30; the mating side of the housing 10 is provided with a locking latching portion 11; the wiring side of the housing 10 is provided with at least two terminal insertion slots 12; each terminal insertion slot 12 corresponds one-to-one with a conductive terminal 30; each conductive terminal 30 is provided with a terminal latching portion 301, and each terminal insertion slot 12 is provided with a terminal latching portion 10 corresponding to the terminal latching portion 301. 1; The terminal latching part 101 is provided with a movable cavity 102 for elastic deformation; The terminal latching part 301 is engaged with the corresponding terminal latching part 101; The locking member 20 is provided with a terminal limiting part 21 corresponding to the movable cavity 102 and a locking latching part 201 corresponding to the locking latching part 11; When the locking member 20 is in the locked state, the locking latching part 201 is engaged with the locking latching part 11; The terminal limiting part 21 is embedded in the movable cavity 102, so that the terminal latching part 101 and the terminal latching part 301 are locked together, and the locking latching part 11 and the locking latching part 201 are locked together. This application uses locking member 20 to simultaneously lock terminal latching part 101 and terminal latching part 301 together, and lock locking part 11 and locking latching part 201 together. This not only fixes the conductive terminal 30, but also allows the locking member 20 to be installed itself, effectively preventing the conductive terminal 30 from loosening or falling off under vibration conditions, and significantly improving the mechanical reliability of the connector and the long-term stability of the electrical connection.

[0023] The following will further describe a terminal limiting connector in this exemplary embodiment.

[0024] It should be noted that the outer shell 10, as the main structure of the connector, serves to accommodate and protect the internal conductive terminals 30 through the wiring side, and to achieve connection and fixation with the locking member 20 and other components through the locking snap-fit ​​part 11 on the mating side.

[0025] The locking latching part 11 can be a groove structure provided on the mating side end face for cooperating with the terminal latching part 301; the terminal insertion groove 12 is an elongated channel opened on the inner wall of the housing 10, and its inner wall is provided with a terminal latching part 101 for cooperating with the conductive terminal 30.

[0026] The terminal latching part 101 may be an elastic arm structure disposed on the inner wall of the terminal insertion groove 12; the terminal latching part 301 may be a latching structure extending from the head or middle of the conductive terminal 30. The terminal latching part 301 cooperates with the terminal latching part 101 inside the housing 10 to fix the conductive terminal 30 inside the housing 10.

[0027] The movable cavity 102 provides a space for the terminal latching portion 101 to be elastically deformable, allowing the terminal latching portion 101 to adapt to the installation of the conductive terminal 30. Simultaneously, the movable cavity 102 also provides a accommodating space for the terminal limiting portion 21 of the locking member 20.

[0028] The locking member 20 is simultaneously embedded in multiple movable cavities 102 through the terminal limiting part 21, so that the terminal latching parts 101 of multiple sets of housings 10 and the terminal latching parts 301 of conductive terminals 30 lock each other. At the same time, the locking member 20 is connected to the locking latching part 11 of housing 10 through the locking latching part 201 to achieve installation and fixation, thus achieving double locking.

[0029] In one specific implementation, the conductive terminal 30 is first inserted into the terminal insertion slot 12 of the housing 10, and the terminal latching part 301 initially engages with the terminal latching part 101 of the housing 10; then the locking member 20 is inserted into the mating side channel of the housing 10, and the locking member 20 is pressed inward to achieve locking without the need for additional tools or operations.

[0030] As an example, the terminal latch 301 may be an elastic tongue disposed in the middle of the conductive terminal 30; the number of the terminal insertion slot 12 and the conductive terminal 30 may be set to 2, 3, 4 or more according to the electrical requirements of the connector; the conductive terminal 30 may be made of conductive materials such as copper alloy, tin-plated copper or silver-plated copper; the locking member 20 may be made of metal or plastic.

[0031] Reference Figure 4 , Figure 5 and Figure 7 In one embodiment of this application, the conductive terminal 30 includes a first terminal 31 and a second terminal 32; the terminal insertion slot 12 includes a first insertion slot 121 and a second insertion slot 122. The locking latching part 11 is disposed between the first insertion slot 121 and the second insertion slot 122; the first terminal 31 is connected to the first insertion slot 121; and the second terminal 32 is connected to the second insertion slot 122.

[0032] It should be noted that the first insertion slot 121 and the second insertion slot 122 correspond to the first terminal 31 and the second terminal 32 respectively, forming independent insertion channels to avoid electrical short circuits or mechanical interference between terminals.

[0033] The locking latch 11 is positioned between the two plug slots, which effectively utilizes the physical distance between the two plug slots for electrical isolation, provides a reference positioning for the installation of the locking member 20, and ensures that the locking member 20 can be simultaneously limited by the two plug slots in the locked state, and reacts to limit the first terminal 31 and the second terminal 32, thereby achieving mutual locking.

[0034] As an example, the first terminal 31 and the second terminal 32 can adopt the same structural design and material specifications; the locking latching part 11 can be a groove-shaped channel structure provided on the mating side of the housing 10; the first insertion groove 121 and the second insertion groove 122 can be arranged in parallel along the length direction of the housing 10.

[0035] Reference Figure 3 and Figure 7 In one embodiment of this application, the terminal limiting part 21 includes a first limiting part 211 and a second limiting part 212; The first limiting part 211 is disposed on the side of the first insertion groove 121 away from the locking latching part 11, and the second limiting part 212 is disposed on the side of the second insertion groove 122 away from the locking latching part 11. When the locking member 20 is in the locked state, the first limiting part 211 is embedded in the movable cavity 102 corresponding to the first insertion slot 121, and the second limiting part 212 is embedded in the movable cavity 102 corresponding to the second insertion slot 122.

[0036] It should be noted that by setting the first insertion slot 121 between the first limiting part 211 and the locking buckle part 201, and setting the second insertion slot 122 between the second limiting part 212 and the locking buckle part 201, the locking member 20 can form a clamping structure in the locked state to limit the terminal axially and radially, thereby further preventing the terminal from loosening.

[0037] As an example, the first limiting part 211 and the second limiting part 212 may be protrusions extending from the locking member 20.

[0038] Reference Figure 5 and Figure 7 In one embodiment of this application, the heads of the first terminal 31 and the second terminal 32 are both flat and arranged parallel to each other; The locking buckle 201 has a U-shaped structure, and its two sides are respectively arranged parallel to the heads of the first terminal 31 and the second terminal 32.

[0039] It should be noted that the flat head design prevents misalignment during installation and insertion, and provides higher rigidity and connection stability; the parallel arrangement of the first terminal 31 and the second terminal 32 facilitates the uniform fixation of the locking member 20. The U-shaped cross-section of the locking buckle 201, which is parallel to the terminal head, can form surface contact with the first insertion groove 121 and the second insertion groove 122 respectively, ensuring uniform distribution of locking force and improving clamping reliability.

[0040] As an example, the heads of the first terminal 31 and the second terminal 32 can have the same flat shape, or they can have different flat shapes to accommodate terminals of different specifications.

[0041] In one specific implementation, the heads of the first terminal 31 and the second terminal 32 are first inserted into the corresponding insertion slots; then the locking member 20 is installed so that the U-shaped locking buckle part 201 and the locking snap part 11 are connected and engaged, while the two sides are respectively set parallel to the flat heads of the two terminals.

[0042] Reference Figure 4 , Figure 5 and Figure 8 In one embodiment of this application, the conductive terminal 30 further includes a third terminal 33 and a fourth terminal 34; the terminal insertion slot 12 includes a third insertion slot 123 and a fourth insertion slot 124. The third insertion slot 123 and the fourth insertion slot 124 are respectively disposed on different sides of the locking latching part 11; the third terminal 33 is connected to the third insertion slot 123; and the fourth terminal 34 is connected to the fourth insertion slot 124.

[0043] It should be noted that the first insertion slot 121, the second insertion slot 122, the third insertion slot 123, and the fourth insertion slot 124 together constitute a complete terminal insertion structure. The arrangement of the third terminal 33 and the fourth terminal 34 expands the electrical connection capability of the connector, enabling it to accommodate four conductive terminals 30 at the same time. The design of the locking latching part 11 located on different sides allows the locking member 20 to uniformly fix the four terminals in the locked state and avoid mutual interference between the terminals.

[0044] As an example, the third terminal 33 and the fourth terminal 34 can be small pin-shaped terminals. The third insertion slot 123 and the fourth insertion slot 124 can be arranged parallel to each other along the length of the housing 10 and distributed on different sides of the plane where the first insertion slot 121 and the second insertion slot 122 are located.

[0045] Reference Figure 3 and Figure 8 In one embodiment of this application, the terminal limiting part 21 further includes a third limiting part 213 and a fourth limiting part 214; When the locking member 20 is in the locked state, the third limiting part 213 is embedded in the movable cavity 102 corresponding to the third insertion groove 123, and the fourth limiting part 214 is embedded in the movable cavity 102 corresponding to the fourth insertion groove 124.

[0046] It should be noted that the third limiting part 213 and the fourth limiting part 214 extend the limiting function of the locking member 20, enabling it to simultaneously limit the four terminals in both directions; the movable cavity 102 provides elastic deformation space for the third limiting part 213 and the fourth limiting part 214; the synergistic effect of the four limiting parts can prevent the corresponding terminal latching part 301 from being excessively deformed in its movable cavity 102, causing the terminal to loosen or fall off.

[0047] As an example, the third limiting part 213 and the fourth limiting part 214 may be protrusions extending from the locking member 20.

[0048] In one specific implementation, the first terminal 31, the second terminal 32, the third terminal 33, and the fourth terminal 34 are first inserted into their respective insertion slots; then the locking member 20 is installed so that the locking latching part 201 of the locking member 20 is engaged with the locking latching part 11, and at the same time the first limiting part 211, the second limiting part 212, the third limiting part 213, and the fourth limiting part 214 are respectively embedded into their respective movable cavities 102.

[0049] Reference Figure 3 and Figure 7 In one embodiment of this application, the locking buckle 201 includes a first locking buckle 2011 and a second locking buckle 2012; When the locking member 20 is in a locked state, the locking latch 11 is engaged with the first locking buckle 2011, and the locking latch 11 is located between the first locking buckle 2011 and the second locking buckle 2012.

[0050] It should be noted that the arrangement of the first locking buckle 2011 and the second locking buckle 2012 enables the locking member 20 to have a multi-level locking function. The first locking state provides basic positioning, and the locking latch 11 is located between the first locking buckle 2011 and the second locking buckle 2012, so that the locking member 20 can be initially installed on the outer shell 10.

[0051] Reference Figure 3 and Figure 7 In one embodiment of this application, when the locking member 20 is in a secondary locking state, the locking latch 11 is engaged with the second locking buckle 2012, and the locking latch 11 is located on the side of the second locking buckle 2012 away from the first locking buckle 2011.

[0052] It should be noted that the first locking buckle 2011 and the second locking buckle 2012 enable the locking member 20 to have a multi-level locking function. The secondary locking state provides reinforced fixation of the terminal and fixation of the locking member 20 itself, thereby improving the reliability of the connector under vibration conditions.

[0053] As an example, the second locking latch 2012 may include at least two.

[0054] In one specific implementation, the locking member 20 is first inserted into the mating side of the housing 10, so that the locking latch 11 is engaged with the first locking buckle 2011, and the locking latch 11 is located between the first locking buckle 2011 and the second locking buckle 2012. After the conductive terminal 30 is installed, the locking member 20 is operated a second time to engage the locking latch 11 with the second locking buckle 2012, and the locking latch 11 is located on the side of the second locking buckle 2012 away from the first locking buckle 2011, thus completing the secondary locking.

[0055] Reference Figure 1 , Figure 2 , Figure 6 and Figure 8 In one embodiment of this application, it further includes: a connecting fastener 4; The outer side of the outer casing 10 is provided with a guide groove 13; the inner side of the guide groove 13 is provided with a snap fastener 131; One side of the connecting fastener 4 is embedded in the guide groove 13 and is connected to the snap fastener 131; The other side of the connecting fastener 4 is provided with a barb 41 for fixing the connector.

[0056] It should be noted that the connecting fastener 4 enables the connector to be mechanically connected to other components; the guide groove 13 provides an insertion channel and guidance for the connecting fastener 4. The snap-fit ​​buckle 131 engages with the connecting fastener 4 to form a stable clamping structure, preventing the connecting fastener 4 from dislodging from the guide groove 13 and improving the reliability of the connection. The barb 41 can be used to connect external devices to secure the connector.

[0057] As an example, the fastener 4 can be a separate metal or plastic component. The barb 41 can be a hook-shaped, serrated, or barb-shaped structure extending from the fastener 4.

[0058] In one specific implementation, the insertion end of the connecting fastener 4 is first embedded into the guide groove 13 on the outside of the housing 10, so that the connecting fastener 4 and the snap fastener 131 are engaged and connected; then a fixing operation is performed so that the barb 41 of the connecting fastener 4 engages with the external fixing component.

[0059] Reference Figure 2 , Figure 7 and Figure 8 In one embodiment of this application, it further includes: a plurality of waterproof rings 5; the waterproof rings 5 ​​correspond one-to-one with the conductive terminals 30; The waterproof ring 5 is disposed on the corresponding conductive terminal 30 and abuts against the inner wall of the corresponding terminal insertion groove 12.

[0060] It should be noted that the waterproof ring 5 further enhances the connector's waterproof and dustproof capabilities, improving its reliability in harsh environments such as humidity, high temperatures, and severe vibration. Each waterproof ring 5 corresponds one-to-one with the conductive terminal 30, ensuring independent sealing protection for each terminal. Furthermore, the waterproof ring 5, located at the tail of each conductive terminal 30 and abutting against the corresponding terminal insertion slot 12, further prevents the terminal from detaching.

[0061] As an example, the waterproof ring 5 can be an annular sealing ring made of elastic materials such as rubber or silicone; the size and shape of the waterproof ring 5 can be designed according to the specifications of the corresponding terminal and the insertion slot. The waterproof ring 5 can have a hollow wiring hole to form a connection channel between the external wire harness and the terminal.

[0062] In one specific implementation, the waterproof ring 5 is first placed at the tail of the conductive terminal 30, and the waterproof ring 5 is held by the tail wing of the conductive terminal 30. Then, the conductive terminal 30 is inserted into the corresponding terminal insertion groove 12, so that the waterproof ring 5 abuts against the inner wall of the terminal insertion groove 12 to form a closed structure.
