Description

Technical Field

[0001] This invention relates to power connector structures, and in particular to a novel power connector female structure that enables the power terminals to be assembled in both directions while simultaneously satisfying the locking function on both sides of the TPA. Background Technology

[0002] Power connectors are widely used connectors. Currently, the power connectors used in the market are based on existing solutions. The terminals generally need to be inserted in a fixed direction, and the correct direction needs to be identified before they can be inserted into the sheath. The assembly process requires the addition of a mistake-proofing station. Existing solutions are costly and relatively complex to operate, resulting in a poor user experience. With the market developing rapidly, many existing power connectors urgently need improvement. Utility Model Content

[0003] To solve the above-mentioned technical problems, this invention provides a novel power connector female structure that enables the power terminals to be assembled in both directions while simultaneously satisfying the locking function on both sides of the TPA.

[0004] The technical solution provided by this invention is: a novel power connector female socket structure, comprising: a shell, a TPA lock, and a terminal assembly.

[0005] The outer casing includes a main body, an inner cavity, a TPA locking groove, housing protrusions, a CPA locking seat, and a CPA lock. The inner cavity is located inside the main body and has an opening on one side. The top and bottom of the inner cavity are both arc-shaped of the same size. The CPA locking seat is located at the top of the main body, and the CPA lock is inserted into the CPA locking seat for locking. The TPA locking groove is located at the bottom of the main body. Housing protrusions are located on the top, bottom, left, and right sides of the main body. The TPA lock is inserted into the TPA locking groove. The terminal assembly includes a terminal sleeve and a power terminal. The terminal sleeve is pressed onto the power terminal. The terminal sleeve has outwardly protruding spring tabs at both the top and bottom. The power terminal near the tail end of the terminal sleeve has a U-shaped tab that opens to the side. The terminal sleeve is inserted into the inner cavity, and the U-shaped tab is engaged with the arc-shaped upper and lower inner walls of the inner cavity. The arc-shaped upper and lower inner walls of the inner cavity are used to prevent incorrect insertion of the terminal sleeve without needing to identify the direction.

[0006] Further optimization includes spring clip holders on both the upper and lower inner walls of the outer shell cavity. These spring clip holders are used to secure the spring clips when the terminal sleeve is reversed and inserted.

[0007] Further optimizations have been made, with the housing protrusions positioned vertically and horizontally to better position and insert the connector female into the socket.

[0008] Further optimizations were made, including two inner cavities in the outer shell; and two terminal assemblies, which were inserted into the two inner cavities of the outer shell respectively.

[0009] Further optimization includes a TPA lock slot with a limiting groove and a locking platform; the limiting groove is located on the side, and the locking platform is located at the bottom; the TPA lock has limiting arms on both sides, with barbs at the top of the limiting arms; the TPA lock has a locking mechanism at the bottom, where the limiting arms engage with the limiting groove and move up and down within the groove, the barbs hook onto the bottom of the limiting groove to restrict the limiting arms from moving further down, and the locking mechanism fastens and secures the locking platform.

[0010] Further optimization includes the TPA lock further comprising a lock platform, wherein there are at least two lock platforms, and a protrusion is provided between the lock platforms. The bottom of the inner cavity of the two outer shells has a groove, and the protrusion is inserted into the groove.

[0011] Further optimizations include a circular crimping ring for the cable at the tail end of the terminal housing, with the locking plate pressing against the crimping ring.

[0012] Compared to previously disclosed technical solutions, the innovation of this new power connector female socket structure lies in the fact that it incorporates an arc-shaped design for the upper and lower inner walls of the housing cavity. This allows for rapid assembly without the need for orientation identification or error prevention during terminal installation. In both forward and reverse assembly states, the TPA lock can secure the reliable performance of both sides of the terminal, achieving a more reliable and stable connection and transmission function.

Detailed Implementation

[0014] The following is in conjunction with the appendix Figures 1 to 6 The present invention will be described in detail with reference to specific embodiments, but this is not intended to limit the present invention. Example

[0015] As attached Figures 1 to 6 As shown, a novel power connector female socket structure includes: a housing 1, a TPA lock 2, and a terminal assembly 3.

[0016] The outer shell 1 includes an outer shell body 11, an inner shell cavity 12, a TPA locking groove 13, a shell protrusion 14, a CPA locking seat 15, and a CPA lock 16. The inner shell cavity 12 is located inside the outer shell body 11 and has an opening on one side. The top and bottom of the inner shell cavity 12 are both arc-shaped of the same size. The CPA locking seat 15 is located at the top of the outer shell body 11, and the TPA locking groove 13 is located at the bottom of the outer shell body 11. The shell protrusion 14 is located on the top, bottom, left, and right sides of the outer shell body 11. The terminal assembly 3 includes a terminal sleeve 31 and a power terminal 32. The terminal sleeve 31 has outwardly protruding spring pieces 311 on both the top and bottom. The power terminal 32 near the tail end of the terminal sleeve 31 has a U-shaped piece 322 that opens to the side. The inner walls of the outer shell cavity 12 have spring piece retainers. The positions of the shell protrusion 14 are respectively vertically and horizontally aligned. The shell protrusion 14 is used to better position and insert the connector female socket when it is mated. The housing has two inner cavities 12; there are two terminal assemblies 3, which are inserted into two inner cavities 12 respectively. The TPA lock slot 13 is provided with a limiting groove 131 and a locking platform 132; the limiting groove 131 is located on the side, and the locking platform 132 is located at the bottom; the TPA lock 2 has limiting arms 21 on both sides, and the top of the limiting arms 21 has a barb 211; the bottom of the TPA lock 2 has a locking lock 22; the TPA lock 2 also includes a locking platform 23, and there are at least two locking platforms 23. A protrusion 24 is provided between the locking platforms 23. There is a groove at the bottom of the middle of the two inner cavities 12. The cable at the tail end of the terminal sleeve 31 is a circular crimping ring 321.

[0017] As attached Figures 1 to 3As shown, an implementation of a novel power connector female socket structure is described: A terminal sleeve 31 is crimped onto a power terminal 32, and the terminal sleeve 31 is inserted into the inner cavity 12 of the outer shell. A U-shaped piece 322 is secured to the upper and lower arc-shaped inner walls of the inner cavity 12. The arc-shaped upper and lower arc-shaped inner walls of the inner cavity 12 are used to prevent incorrect insertion of the terminal sleeve 31 without needing to identify the direction. A spring clip is used to secure the spring clip 311 when the terminal sleeve 31 is inserted in reverse. A CPA lock 16 is inserted into a CPA lock seat 15 for locking. A limiting arm 21 is inserted into a limiting groove 131 and moves up and down within the groove. A barb 211 hooks onto the bottom of the limiting groove 131, restricting the limiting arm 21 from moving further down. A locking lock 22 is secured to the locking platform 132. A protrusion 24 is inserted into a groove. A locking platform 23 is pressed against the crimping ring 321. The TPA lock 2 is inserted into the TPA lock slot 13. Combined with the arc-shaped design of the upper and lower inner walls of the inner cavity 12 of the outer shell, the terminals can be quickly assembled without the need for orientation identification or foolproofing. The TPA lock can lock both sides of the terminal in both positive and negative assembly states, achieving a more reliable and stable connection and transmission function.
