Description

Technical Field

[0001] This invention belongs to the field of connector technology, and particularly relates to a wire-end connector. Background Technology

[0002] Electronic connectors, also commonly known as electrical connectors, are conductive devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. They are widely used in various electrical circuits to connect or disconnect current or signals. Cable connectors are electrical connectors attached to the ends of cables, used to electrically connect cables to other cables or circuit boards.

[0003] Currently, the method for securing cables and connectors is as follows: one end of the cable passes through the connector's plug housing, and the securing structure is inserted into the plug housing from its side wall, with the end of the securing structure abutting against the circumferential groove of the cable. With this method, the securing structure is prone to detaching from the plug housing due to insufficient penetration, resulting in an unreliable connection between the cable and connector, thus affecting the conduction of current or signals.

[0004] Therefore, there is an urgent need for a wire-end connector to solve the above-mentioned technical problems. Summary of the Invention

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0054] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0055] like Figures 1 to 4 As shown, this embodiment provides a wire-end connector, which includes a plug housing 1 and a fixing member 2. The plug housing 1 is provided with a fixing section 11 and an insertion section 12 connected to each other along a first direction. The fixing section 11 and the insertion section 12 are provided with a cable mounting groove 13 through the first direction. The cable mounting groove 13 is used to pass through the cable 10. The side wall of the fixing section 11 is provided with an insertion groove 111 that communicates with the cable mounting groove 13. The insertion section 12 can be inserted into the docking housing 20 of the docking connector. The fixing member 2 includes a main body 23 and an extension 24 connected to each other along the first direction. The main body 23 is provided with a first cable limiting part 21. The main body 23 can be inserted into the insertion groove 111. The first cable limiting part 21 is engaged in the circumferential groove 101 of the cable 10, and the extension 24 is inserted into the docking housing 20.

[0056] In this embodiment, when connecting cable 10, the connecting end of cable 10 passes through the cable mounting groove 13 of plug housing 1. Then, the fixing member 2 is inserted into the insertion groove 111 of plug housing 1. At this time, the first cable limiting part 21 is engaged in the circumferential groove 101 of cable 10, realizing the connection between plug housing 1 and cable 10. When the line connector is mated with the mating connector, the insertion section 12 and the extension part 24 are simultaneously inserted into the mating housing 20, so that the mating connector plays a limiting role on the fixing member 2, preventing the fixing member 2 from coming out of the insertion groove 111, thereby improving the connection strength between the line connector and cable 10, and thus ensuring the normal conduction of current or signal.

[0057] Specifically, the insertion section 12 has an embedding groove 121, and the extension 24 is embedded in the embedding groove 121. The extension 24 is simultaneously inserted into the docking housing 20 along with the insertion section 12, and the extension 24 is restricted from detachment by the docking housing 20 to achieve an anti-detachment effect.

[0058] Specifically, locking grooves 112 are provided on both inner sidewalls of the insertion slot 111 along the second direction, which is perpendicular to the first direction. Locking heads 221 protrude from both ends of the main body 23 along the second direction, and these locking heads 221 are correspondingly engaged within the locking grooves 112. The locking grooves 112 are blind grooves. The cooperation between the locking grooves 112 and the locking heads 221 enables the main body 23 and the insertion slot 111 to connect. Since the locking grooves 112 are blind grooves, their presence does not severely affect the structural strength of the plug housing 1. In other words, this embodiment improves the reliability of the connection between the wire connector and the cable 10 while ensuring sufficient structural strength of the plug housing 1, thereby guaranteeing the normal conduction of current or signals.

[0059] More specifically, such as Figure 2 and Figure 3 As shown, each locking slot 112 has a pre-locking slot 113 on one side near the opening of the insertion slot 111. The pre-locking slots 113 and their corresponding locking slots 112 are spaced apart. The pre-locking slots 113 are blind slots, and the locking heads 221 can be engaged in the pre-locking slots 113 one by one. When the cable 10 is not inserted, the fixing member 2 is partially inserted into the insertion slot 111, and the locking heads 221 are engaged in the pre-locking slots 113 one by one, realizing the pre-locking of the fixing member 2 and the plug housing 1. At this time, the fixing member 2 has not yet been inserted into the cable installation slot 13, and the cable 10 can be inserted. After the cable 10 is inserted, the fixing member 2 is inserted again, so that the locking heads 221 are engaged in the locking slots 112 one by one. At this time, the first cable limiting part 21 is engaged in the circumferential groove 101 of the cable 10, realizing the fixation of the cable 10. The cooperation between the pre-locking groove 113 and the locking head 221 achieves pre-locking of the fastener 2, preventing the fastener 2 from being lost.

[0060] More specifically, such as Figure 7 As shown, the locking head 221 includes an insertion guide ramp 2211 and an exit guide ramp 2212 arranged opposite to each other. The insertion guide ramp 2211 allows the locking head 221 to slide smoothly into the pre-locking groove 113 or the locking groove 112, and the exit guide ramp 2212 allows the locking head 221 to slide smoothly out of the pre-locking groove 113 or the locking groove 112.

[0061] Specifically, such as Figure 1 and Figure 6 As shown, a second cable limiting part 131 is provided on the inner wall of the cable mounting groove 13, which can be engaged in the circumferential groove 101 of the cable 10. The engagement of the second cable limiting part 131 and the circumferential groove 101 further improves the reliability of fixing the cable 10.

[0062] Specifically, the plug housing 1 has multiple parallel and spaced cable mounting slots 13, and the outer wall of the plug housing 1 has multiple spaced insertion slots 111. Each insertion slot 111 is connected to several cable mounting slots 13, and each insertion slot 111 is used to insert a main body part 23. This arrangement allows the plug housing 1 to simultaneously fix multiple cables 10. In this embodiment, the plug housing 1 has four cable mounting slots 13 arranged in two rows and two columns. One cable 10 passes through each cable mounting slot 13. Each of the two opposite outer walls of the plug housing 1 has an insertion slot 111, and each insertion slot 111 is connected to two cable mounting slots 13. That is, each fixing member 2 fixes two cables 10.

[0063] Specifically, such as Figure 7 As shown, the main body 23 also includes two elastic arms 22. One end of each elastic arm 22 is connected to one end of the main body 23 along the second direction, and the other end of each elastic arm 22 is provided with a locking head 221. The elastic arm 22 deforms so that the locking head 221 can be smoothly engaged with the locking groove 112 or the pre-locking groove 113.

[0064] In this embodiment, as Figure 3 and Figure 6 As shown, each elastic arm 22 has a first cable limiting part 21 on its inner wall. The middle part of the main body 23 is connected to a middle plate between the two elastic arms 22. The middle plate includes two first cable limiting parts 21 arranged opposite to each other along the second direction. The first cable limiting part 21 on each elastic arm 22 and one first cable limiting part 21 on the middle plate are engaged with the circumferential groove 101 of the same cable 10, so that the fixing member 2 can fix two cables 10 at the same time.

[0065] Specifically, such as Figure 3 and Figure 7 As shown, the main body 23 has two first cable limiting parts 21 arranged opposite each other in the second direction for each cable mounting slot 13. The second cable limiting part 131 in each cable mounting slot 13 can be fitted between the two first cable limiting parts 21 on the corresponding main body 23. This arrangement ensures that at least half of the circumferential groove 101 of the cable 10 is limited by the first cable limiting part 21 and the second cable limiting part 131, further guaranteeing the reliability of fixing the cable 10.

[0066] Specifically, such as Figure 2 As shown, the main body 23 has a positioning groove 231, and the fixing section 11 has a positioning boss 114. The positioning boss 114 can be positioned and inserted into the positioning groove 231. The cooperation between the positioning groove 231 and the positioning boss 114 realizes the alignment and insertion of the fixing member 2 and the plug housing 1.

[0067] In this embodiment, the fastener 2 is an integrally molded structure, which reduces manufacturing costs and improves the overall structural strength.

[0068] Specifically, the wire connector provided in this embodiment further includes a snap-fit ​​spring 3 and a locking member 4. One end of the snap-fit ​​spring 3 is connected to the outer wall of the insertion section 12, and the other end extends towards the fixed section 11 along a first direction. The snap-fit ​​spring 3 can snap into the snap-fit ​​groove 201 of the mating housing 20 of the mating connector. The locking member 4 is movably disposed in the plug housing 1 to prevent the snap-fit ​​spring 3 from disengaging from the snap-fit ​​groove 201. When the wire connector and the mating connector are mated, the insertion section 12 and the extension 24 are inserted into the mating groove 202 of the mating housing 20, and the snap-fit ​​spring 3 snaps into the snap-fit ​​groove 201. This configuration improves the reliability of the insertion of the wire connector and the mating connector.

[0069] Specifically, in this embodiment, the mating connector is a board-end connector, which is connected to the circuit board 30. The wire-end connector and the board-end connector are mated to achieve electrical conduction between the cable 10 and the circuit board 30. The electrical components within the plug housing 1 and the mating housing 20 and their interconnections are well known to those skilled in the art and will not be described in detail here.

[0070] Specifically, such as Figure 4 , Figure 5 and Figure 8As shown, the locking member 4 includes a base 41, which is movably disposed on the plug housing 1. The base 41 can reciprocate between a locked position and an unlocked position along a first direction. The base 41 includes an abutment portion 411 and a snap-fit ​​portion 4121 connected to the abutment portion 411. A limiting groove 31 is formed on the snap-fit ​​spring 3. When the base 41 is in the locked position, the abutment portion 411 abuts against the side of the snap-fit ​​spring 3 away from the snap-fit ​​groove 201. When the base 41 is in the unlocked position, the snap-fit ​​spring 3 and the abutment portion 411 are spaced apart, and the snap-fit ​​portion 4121 is limited in the limiting groove 31 to restrict the movement of the base 41 in the first direction.

[0071] In this embodiment, when the plug housing 1 and the docking housing 20 need to be locked, the base 1 moves to the locked position. At this time, the abutment part 411 abuts against the side wall of the snap-fit ​​spring 3 away from the snap-fit ​​groove 201. Therefore, the snap-fit ​​spring 3 will not deform away from the snap-fit ​​groove 201, that is, the snap-fit ​​spring 3 will not detach from the snap-fit ​​groove 201, thereby ensuring the firmness of the connection between the plug housing 1 and the docking housing 20. When the plug housing 1 and the docking housing 20 need to be unlocked, the base 1 moves to the unlocked position. At this time, the snap-fit ​​spring 3 and the abutment part 411 are spaced apart, and a force away from the snap-fit ​​groove 201 can be applied to the snap-fit ​​spring 3 to drive the snap-fit ​​spring 3 to detach from the snap-fit ​​groove 201, thereby completing the unlocking of the plug housing 1 and the docking housing 20. At the same time, the snap-fit ​​part 4121 is limited by the limiting groove 31 on the snap-fit ​​spring 3 to limit the movement of the base 41 in the first direction, thereby preventing the locking member 4 from detaching from the plug housing 1 and avoiding the loss of the locking member 4.

[0072] Specifically, the first direction is the mating direction of the wire connector and the mating connector.

[0073] When it is necessary to lock the wire end connector and the mating connector, the base 1 moves to the locked position, and the abutment part 411 abuts against the side wall of the snap-fit ​​spring 3 facing the fixed section 11, ensuring the firmness of the connection between the wire end connector and the mating connector. When it is necessary to separate the wire end connector and the mating connector, the base 1 moves to the unlocked position, and there is a gap between the snap-fit ​​spring 3 and the abutment part 411. The snap-fit ​​part 4121 is limited to the limiting groove 31. At this time, a force is applied to the snap-fit ​​spring 3 away from the snap-fit ​​groove 201 to drive the snap-fit ​​spring 3 to disengage from the snap-fit ​​groove 201, thereby completing the unlocking. Then, the wire end connector and the mating connector move away from each other, thus completing the separation operation of the wire end connector and the mating connector.

[0074] Specifically, such as Figure 8 As shown, a sliding groove 115 extending along a first direction is provided on the fixed section 11, and the base 41 is slidably connected to the sliding groove 115. The sliding groove 115 enables the sliding connection between the base 41 and the fixed section 11, making the movement of the base 41 more stable.

[0075] More specifically, such as Figure 9 As shown, the two opposite inner walls of the sliding groove 115 are provided with sliding grooves 1151. The two ends of the base 41 along the second direction are respectively slidably connected to the two sliding grooves 1151. The setting of the sliding grooves 1151 realizes the sliding connection between the base 41 and the fixed section 11, so that the base 41 can only move along the first direction relative to the fixed section 11, thereby ensuring the smooth movement of the base 41.

[0076] Specifically, such as Figure 9 and Figure 10 As shown, the base 41 also includes a limiting protrusion 43, which is connected to the end of the abutment portion 411 along the second direction. The inner wall of the sliding groove 115 of the fixing section 11 has a first groove 1152 and a second groove 1153 spaced apart along the first direction. When the base 41 is in the locked position, the limiting protrusion 43 is limited to the first groove 1152 on the plug housing 1. When the base 41 is in the unlocked position, the limiting protrusion 43 is limited to the second groove 1153 on the plug housing 1. That is, when the base 41 is in the locked position, the limiting protrusion 43 and the first groove 1152 cooperate to limit the position of the base 41, ensuring the reliability of the base 41 abutting against the snap-fit ​​spring 3, further improving the firmness of the connection between the wire end connector and the mating connector; when the base 41 is in the unlocked position, the limiting protrusion 43 and the second groove 1153 cooperate to limit the position of the base 41, further preventing the locking member 4 from disengaging from the plug housing 1.

[0077] Specifically, in this embodiment, such as Figures 9 to 11 As shown, the base 41 includes two limiting protrusions 43, which are respectively connected to the two ends of the abutment portion 411 along the second direction. The two opposing inner walls of the sliding groove 115 of the fixed section 11 are provided with a first groove 1152 and a second groove 1153. The two limiting protrusions 43 cooperate with the first groove 1152 or the second groove 1153 on both sides to limit the base 41, so as to improve the limiting effect of the base 41.

[0078] More specifically, such as Figure 11 As shown, the side of the limiting protrusion 43 near the snap-fit ​​spring 3 includes a first guide slope 431. The first guide slope 431 facilitates the limiting protrusion 43 to slide into the second groove 1153 from the outside, and to slide into the first groove 1152 from the second groove 1153. In this embodiment, the side of the limiting protrusion 43 opposite to the first guide slope 431 includes a third guide slope. The third guide slope facilitates the limiting protrusion 43 to slide into the second groove 1153 from the first groove 1152, and to slide out of the second groove 1153 from the outside.

[0079] Specifically, such as Figure 11As shown, a clearance groove 44 is provided on the base 41, and a first elastic deformation portion 45 is provided between the clearance groove 44 and the limiting protrusion 43. When the limiting protrusion 43 slides to abut against the inner wall of the sliding groove 115, the inner wall of the sliding groove 115 applies a squeezing force to the limiting protrusion 43. The limiting protrusion 43 squeezes the first elastic deformation portion 45 and undergoes elastic deformation towards the clearance groove 44, which avoids the limiting protrusion 43 and the inner wall of the sliding groove 115 being squeezed too tightly, thus affecting the smooth sliding of the base 41. When the limiting protrusion 43 moves to the first groove 1152 or the second groove 1153, the squeezing force on the limiting protrusion 43 is removed, the elastic deformation portion 15 returns to its original shape, and drives the limiting protrusion 43 to move into the first groove 1152 or the second groove 1153.

[0080] More specifically, two first elastic deformation portions 45 are respectively protruding from both ends of the abutment portion 411 along the second direction, and the two first elastic deformation portions 45 are respectively slidably disposed in the two sliding grooves 1151.

[0081] Specifically, such as Figure 12 As shown, a blocking block 33 is provided on the side of the limiting groove 31 near the free end of the snap-fit ​​spring 3. The blocking block 33 prevents the snap-fit ​​part 4121 from exiting the limiting groove 31, ensuring the reliable limiting of the limiting groove 31 on the snap-fit ​​part 4121.

[0082] More specifically, the end wall of the blocking block 33 near the limiting groove 31 includes a second guide slope 331. The second guide slope 331 facilitates the locking part 4121 to slide into the limiting groove 31 when the locking member 4 is assembled with the plug housing 1, and also facilitates the removal of the locking member 4 from the plug housing 1.

[0083] Specifically, such as Figure 11 and Figure 13 As shown, the base 41 includes a second elastic deformation portion 412. One end of the second elastic deformation portion 412 is connected to the abutment portion 411, and the other end extends obliquely toward the snap-fit ​​spring 3. The snap-fit ​​portion 4121 is disposed at the end of the second elastic deformation portion 412 that is away from the abutment portion 411. This arrangement ensures that the snap-fit ​​portion 4121 is always in contact with the side wall of the snap-fit ​​spring 3 facing the fixed section 11, thus guaranteeing that the snap-fit ​​portion 4121 can be smoothly snapped into the limiting groove 31.

[0084] More specifically, a material reduction groove 4122 is provided on the second elastic deformation portion 412, and the outer edge of the end of the material reduction groove 4122 opposite to the abutment portion 411 is a locking portion 4121. The material reduction groove 4122 reduces the amount of material and forms the locking portion 4121.

[0085] Specifically, such as Figure 13As shown, the end of the abutment portion 411 near the snap-fit ​​spring 3 includes a first abutment slope 4111. When the base 41 is in the locked position, the first abutment slope 4111 abuts against the snap-fit ​​spring 3. The provision of the first abutment slope 4111 increases the contact area between the abutment portion 411 and the snap-fit ​​spring 3, further improving the limiting effect on the snap-fit ​​spring 3. Moreover, the first abutment slope 4111 makes the end of the abutment portion 411 near the snap-fit ​​spring 3 thinner, allowing it to smoothly penetrate between the snap-fit ​​spring 3 and the fixing section 11. Furthermore, it can guide the free end of the snap-fit ​​spring 3 to move along the direction toward the snap-fit ​​groove 201, so that the snap-fit ​​protrusion of the snap-fit ​​spring 3 is firmly snapped into the snap-fit ​​groove 201.

[0086] More specifically, in this embodiment, as Figure 9 As shown, the end of the snap-fit ​​spring 3 near the abutment portion 411 includes a second abutment slope 32, such as... Figure 13 As shown, the end of the abutment portion 411 near the snap-fit ​​spring 3 includes a first abutment slope 4111 that abuts against the second abutment slope 32. This arrangement ensures that the abutment portion 411 smoothly penetrates between the snap-fit ​​spring 3 and the fixing section 11, and that the snap-fit ​​protrusion of the snap-fit ​​spring 3 is firmly snapped into the snap-fit ​​groove 201. Furthermore, the abutment of the second abutment slope 32 and the first abutment slope 4111 further increases the contact area between the snap-fit ​​spring 3 and the abutment portion 411, thereby further improving the limiting effect on the snap-fit ​​spring 3.

[0087] Specifically, such as Figure 13 As shown, the locking member 4 also includes a pressing member 42, one end of which is connected to the base 41, and the other end is a pressing part 421, as shown. Figure 9 As shown, a slot 116 extending along a first direction is provided on the fixed section 11. The slot 116 is located at one end of the sliding groove 115 and communicates with the sliding groove 115. The free end of the snap-fit ​​spring 3 passes through the slot 116 and extends into the sliding groove 115. The pressing part 421 of the pressing member 42 is movably inserted into the slot 116. When the base 41 is in the locked position, the pressing part 421 presses against the side of the snap-fit ​​spring 3 away from the pressing part 411. The pressing member 42 further limits the snap-fit ​​spring 3, further improving the limiting effect of the snap-fit ​​spring 3.

[0088] More specifically, the side of the pressing member 42 facing away from the base 41 is provided with a plurality of sequentially spaced protrusions 422. The protrusions 422 are used to increase friction and facilitate the movement of the locking member 4 by hand.

[0089] Specifically, in this embodiment, the locking component 4 is an integrally formed structure, which reduces manufacturing costs and improves the overall structural strength.
