Description

Technical Field

[0001] This utility model belongs to the field of connectors, and in particular relates to a power connector housing, a power connector, and a connector assembly. Background Technology

[0002] Currently, most mainstream power connector housings rely solely on four surrounding enclosed terminal receiving channels to install and secure the conductive terminals. In actual mating operations, the conductive terminals are susceptible to external pressure or friction, causing them to shift backward along the channel axis or even disengage from the insulating body. This problem directly disrupts the stable contact between the conductive terminals and the mating components, leading to anything from reduced power transmission efficiency and increased contact resistance to signal interruption, equipment failure, and even arcing due to poor contact, posing safety hazards and severely impacting the stability and reliability of the power connector connection.

[0044] Example 1:

[0045] like Figures 1 to 7 As shown, this embodiment provides a power connector housing, including an insulating body 1 and an outer shell 7. The insulating body 1 has a mating portion 2, and the interior of the mating portion 2 has terminal receiving channels 3 and terminal stop members 4 respectively. The terminal receiving channels 3 have an opening on one side near the horizontal center line of the mating portion 2, and the opening is opposite to the terminal stop member 4, which is located outside the terminal receiving channels 3. There are two rows of terminal receiving channels 3, which are arranged vertically at intervals, and each row of terminal receiving channels 3 is spaced along the length direction of the insulating body 1. The upper row of terminal receiving channels 3 has an opening on its lower side, and the lower row of terminal receiving channels 3 has an opening on its upper side. A locking member 6 is provided on the top of the insulating body 1. In this embodiment, the outer shell 7 is detachably connected to the insulating body 1. In other embodiments, it can also be fixedly connected to the insulating body 1.

[0046] The terminal stop 4 and the opening of the terminal receiving channel 3 are positioned opposite each other, directly blocking the conductive terminal 8 from the axial direction. This design counteracts the axial backward thrust on the conductive terminal 8 during insertion, preventing the conductive terminal 8 from shifting backward along the terminal receiving channel 3. This ensures that the conductive terminal 8 and the mating parts 2 maintain stable contact, completely eliminating the risk of poor contact and signal interruption caused by the conductive terminal 8 retraction. Furthermore, the peripheral opening of the terminal receiving channel 3 allows operators to directly observe the installation position of the conductive terminal 8. During assembly, it is clear whether the conductive terminal 8 is fully inserted and precisely fitted with the terminal stop 4, avoiding hidden errors such as terminal misalignment and loose clamping caused by blind assembly in traditional closed terminal receiving channels 3, significantly improving assembly accuracy and first-pass yield. Additionally, the peripherally open terminal receiving channel 3 simplifies mold design compared to a fully enclosed channel.

[0047] The terminal stop member 4 includes a limiting part 41 and a stop wall 42. The limiting part 41 and the terminal receiving channel 3 enclose and form an installation space 5 for limiting and fixing the conductive terminal 8. The front end of the limiting part 41 has a stop wall 42. By cooperating with the terminal receiving channel 3 with its peripheral opening, the limiting part 41 forms a surrounding enclosure and fixation of the conductive terminal 8, ensuring the installation stability of the conductive terminal 8. The stop wall 42 further limits the conductive terminal 8, preventing it from moving backward or even coming out of the insulating body 1.

[0048] The limiting part 41 has an extension 43 at its front end, which is positioned near the horizontal centerline of the docking part 2 relative to the stop wall 42. The extension 43 cooperates with the spring structure of the conductive terminal 8, and the elasticity allows the conductive terminal 8 to be more securely installed in the docking part 2.

[0049] The extension section 43 has guide portions 44 on both the left and right sides of the side wall near the stop wall 42. The guide portions 44 guide the stop portion 81 of the conductive terminal 8.

[0050] The limiting part 41 has a clearance groove 45 on the side away from the horizontal centerline of the docking part 2, and the clearance groove 45 is located behind the stop wall 42. The limiting parts 41 on both sides of the clearance groove 45 have guide walls 46. When installing the conductive terminal 8, the conductive terminal 8 can be pushed from back to front to insert it into the installation space 5. Initially, the stop part 81 of the conductive terminal 8 is guided by the guide wall 46 and gradually squeezed by the end face of the limiting part 41, changing from the original inclined state to a horizontal state. During this process, clearance is made by the clearance groove 45. Until the conductive terminal 8 moves forward until its stop part 81 is in front of the stop wall 42, the stop part 81 of the conductive terminal 8 loses the squeeze of the limiting part 41, returns to the inclined state, and abuts against the extension section 43. When the conductive terminal 8 moves backward, it will drive the stop part 81 to move backward. When the stop part 81 moves backward and abuts against the stop wall 42, the conductive terminal 8 can no longer move backward.

[0051] Example 2:

[0052] like Figures 8 to 12 As shown, this embodiment provides a power connector, including a power connector housing as in Embodiment 1, a conductive terminal 8, and a cable 9. The rear end of the conductive terminal 8 is electrically connected to the cable 9, and the front end of the conductive terminal 8 passes through the insulating body 1 and extends into the mating portion 2. The rear end of the cable 9 extends out of the insulating body 1. The conductive terminal 8 has a stop portion 81 on one side near the horizontal centerline of the mating portion 2. In this embodiment, the rear end of the stop portion 81 abuts against the front end of the terminal stop member 4. In other embodiments, the stop portion 81 may be located a short distance in front of the front end of the terminal stop member 4. The stop portion 81 cooperates with the terminal stop member 4 to prevent the conductive terminal 8 from retracting.

[0053] The stop portion 81 is a spring piece that extends obliquely from the conductive terminal 8. The front end of the limiting portion 41 has an extension section 43, which is positioned near the horizontal centerline of the mating portion 2 relative to the stop wall 42, and the stop portion 81 abuts against the extension section 43. The spring piece is elastic, and its elastic force acts on the extension section 43 to improve the installation stability of the conductive terminal 8.

[0054] The device also includes a housing 7 and a pull strap 11. A locking element 6 is provided on the top of the insulating body 1. The housing 7 is detachably connected to the insulating body 1. One end of the pull strap 11 is connected to the locking element 6, and the other end of the pull strap 11 passes through or around the housing 7 and extends out of the housing 7. The housing 7 has an isolation space 12, within which at least a portion of the cable 9 extending out of the insulating body 1 is located. The housing 7 isolates and protects the cable 9 extending out of the insulating body 1, preventing the cable 9 from contacting other components and keeping the cable 9 neat.

[0055] The locking element 6 has a connecting hole 13, and the outer casing 7 has a through hole 10 for the pull strap 11 to pass through. The pull strap 11 passes through the through hole 10 and connects to the connecting hole 13. The through hole 10 is located below and behind the connecting hole 13. Due to the positioning of the through hole 10 and the connecting hole 13, when the pull strap 11 is pulled backward, the locking element 6 is subjected to a backward and downward inclined pulling force. This pulling force can be decomposed into a vertically downward force and a horizontally backward pulling force. The vertically downward pulling force allows the locking element 6 to unlock, and the horizontally backward pulling force can pull the power connector out of the mating connector, enabling quick and easy unlocking of the power connector.
