Description

Technical Field

[0001] The utility model belongs to the technical field of automobile connectors, and in particular relates to a split connector. Background Art

[0002] Terminals are the components that connect batteries to external conductors. They often refer to wiring terminals, also known as terminal blocks. Their primary function is to transmit electrical signals or conduct electricity. Connectors are components used in automotive circuits, serving as a hub for power and signal transmission. TPA connectors (Terminal Retention Assist) provide secondary protection and position limiting for wired terminals, preventing them from pulling out under external forces and causing line interruptions. They are used in harsh environments or when higher pullout forces are required.

[0003] On the other hand, existing connectors include a connector housing and a TPA locking plate. The terminals are inserted into the terminal holes on the connector housing, and the TPA locking plate is inserted into the TPA slot provided on the connector housing. The TPA locking plate and the connector housing are snap-fitted together to provide a secondary securement of the terminals. Currently, various types of split connectors exist, and their split and detachable parts are generally TPAs.

[0004] For example, a Chinese utility model patent with patent publication number CN217405767U and publication date 2022.09.09 discloses a hybrid connector male end sheath assembly with a TPA structure, the structure of which includes: a male end sheath body, terminals and a TPA structure plugged into the male end sheath body, the terminals and the TPA structure are arranged vertically, and sealing structures are respectively provided between the male end sheath and the terminals, and between the male end sheath and the TPA structure.

[0005] The general structural principle of the hybrid connector male end housing assembly in this utility model patent is as follows: the sealing ring is assembled to the card slot of the TPA structure, the sealing plugging ring I and the sealing plugging ring II are crimped to the terminal I and the terminal II respectively, and the assembled TPA structure is installed in the pre-installed position of the hybrid male end housing body. At this time, the pre-installed position hanging nose on the TPA is matched with the pre-installed position hanging platform on the hybrid housing. After the TPA structure is installed in the pre-installed position, the terminal with the crimped sealing plugging ring is inserted into the corresponding terminal hole of the hybrid connector male end housing. At this time, the spring structure on the terminal is matched with the hanging platform on the housing. After the terminal is assembled in place, the TPA in the pre-installed position is pressed to the locking position. At this time, the locking position hanging nose is connected to the locking position hanging platform.

[0006] However, the guide correction device still has at least the following deficiencies during actual use, in other words, these are the technical problems to be solved by the present utility model.

[0007] The installation method between the connector main structure and TPA is to insert the hanging platform into the opening. In order to ensure the structural strength of TPA, the opening structure on it cannot be made larger, which leads to insufficient structural strength of the above insertion method.

[0008] Therefore, in summary, a new type of split connector is urgently needed to solve the barriers of existing technologies. Utility Model Content

[0009] The utility model provides a split connector, which can be arranged on the connector body in a manner such that: the TPA card cover unit is inserted into the combined slot unit on the connector body, and is engaged and connected by the combined slot unit and the fixed frame unit on the TPA card cover unit, thereby ensuring that the terminal and the connector body are installed in place, and the terminal is installed and locked by utilizing the double engagement of the TPA card cover unit, the combined slot unit and the fixed frame unit. The structure is simple and the installation is firm, and the locking state can be identified by a prompt sound.

[0010] The technical solution adopted by the present invention to solve the above-mentioned problem is: a split connector, the structure of which includes a connector body, a combination slot unit arranged on the connector body, a TPA card cover unit arranged on the combination slot unit and used to fix the terminal, and a plurality of pairs of fixing frame units respectively arranged on the combination slot unit and the TPA card cover unit and used to engage with each other.

DETAILED DESCRIPTION

[0033] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0034] As attached Figure 1-8 As shown, a split connector structure includes a connector body 11, a combination slot unit 1 arranged on the connector body 11, a TPA card cover unit 2 arranged on the combination slot unit 1 and used to fix the terminal a, and several pairs of fixing frame units 3 respectively arranged on the combination slot unit 1 and the TPA card cover unit 2 and used to engage with each other.

[0035] In this embodiment, the connector body 11 is provided with the combination slot unit 1, and the combination slot unit 1 is used to insert the TPA card cover unit 2. The terminal a is doubly locked by the TPA card cover unit 2 and the connector body 11, so that the terminal a is firmly installed and not easy to fall off.

[0036] In addition, the fixed frame unit 3 is respectively arranged on the combination slot unit 1 and the TPA card cover unit 2. The combination slot unit 1 and the TPA card cover unit 2 are snap-connected through the fixed frame unit 3, and the connection is firm, which effectively solves the hidden dangers brought about by the hanging platform plus open hole connection method.

[0037] The combined slot unit 1 includes a mounting slot 101 provided on the connector body 11 and used for inserting the TPA card cover unit 2 , and a limiting slot 102 provided on the mounting slot 101 and used for engaging the TPA card cover unit 2 .

[0038] In this embodiment, the mounting groove 101 is provided at the side end of the connector body 11 for inserting the TPA card cover unit 2. The limiting groove 102 is provided on the same side as the mounting groove 101 and is used to insert the TPA card cover unit 2, thereby limiting the position of the TPA card cover unit 2 and ensuring that the TPA card cover unit 2 and the connector body 11 are kept in the same plane as much as possible, thereby enhancing the integrity.

[0039] The TPA card cover unit 2 includes a hole block 201 provided on the installation slot 101 and used to fix the terminal a, and an outer cover plate 202 provided on all the hole blocks 201 and used to engage with the limiting slot 102.

[0040] In this embodiment, the opening block 201 is used to insert the terminal a. An outer cover plate 202 is provided at a side end of the opening block 201 , and the outer cover plate 202 is engaged in the limiting groove 102 .

[0041] The fixing frame unit 3 includes an inserting plate 301 provided on the installation slot 101 or the outer cover 202 , and a protruding strip 302 provided on the inserting plate 301 and configured to engage with each other.

[0042] In this embodiment, the insertion plate 301 is disposed on the mounting slot 101 or the outer cover plate 202, and the combination slot unit 1 and the TPA card cover unit 2 are correspondingly provided with the fixing frame unit 3. The protruding strips 302 are disposed at both outer ends of the insertion plate 301 on the mounting slot 101, and the protruding strips 302 are disposed at both inner ends of the insertion plate 301 on the outer cover plate 202, thereby ensuring that the fixing frame units 3 on the combination slot unit 1 and the TPA card cover unit 2 engage with each other and ensure the connection strength between the combination slot unit 1 and the TPA card cover unit 2. Similarly, the directions of the protruding strips 302 on the combination slot unit 1 and the TPA card cover unit 2 can be reversed without affecting the mutual engagement function of the fixing frame units 3. In addition, in order to increase the accuracy and firmness of the TPA card cover unit 2 when inserted into the combination slot unit 1, the insertion plate 301 can be set asymmetrically, and the insertion plate 301 is provided with a long plate and a short plate, thereby ensuring the clamping strength of the fixed frame unit 3.

[0043] At least two protruding strips 302 are provided on a single insertion plate 301 .

[0044] In this embodiment, at least two protruding strips 302 are provided on the inserting plate 301, so that after the first protruding strip 302 is engaged, as shown in the attached Figure 5 and attached Figure 7 As shown, the fixing frame unit 3 is in a pre-locked state, at which time the terminal a can be placed for preliminary positioning. After the terminal a is installed, the TPA cover unit 2 is further pushed toward the combination slot unit 1 so that the second protruding strip 302 engages with each other. Figure 6 and attached Figure 8As shown, the fixed frame unit 3 is in the final locking state, and the terminal a is finally installed and limited. The protruding strips 302 will make a "click" prompt sound during the mutual locking process. The number of prompt sounds in the final locking state is determined according to the number of protruding strips 302, making installation more convenient. When disassembling, it is only necessary to use a dial pin to gently pry the fixed frame unit 3 that is engaged with each other at both ends. Due to the elastic properties of the material itself, it can be bent to a certain position and then gently pried apart to return to the pre-locked state. At this time, a special tool can be used to remove the terminal a. After removing the terminal a, use the dial pin again to bend it and then remove the TPA card cover unit 2.

[0045] The fixing frame unit 3 further includes a docking inclined surface 303 provided on the insertion plate 301 .

[0046] In this embodiment, the protruding strips 302 need to use a relatively large force to engage with each other, so the inclined surface 303 makes the engagement resistance of the protruding strips 302 smaller.

[0047] A sealing rubber pad 4 is further provided on the installation groove 101 and / or the outer cover plate 202 .

[0048] In this embodiment, the sealing rubber pad 4 functions to reduce the impact loss of the protruding strip 302 on the connector body 11 or the TPA card cover unit 2 , and the sealing rubber pad 4 can also achieve good shock absorption and waterproofing effects.

[0049] The TPA card cover unit 2 further includes a main body engaging groove 203 provided on the outer cover plate 202 .

[0050] In this embodiment, the main body engaging groove 203 is used to cooperate with the structure on the connector body 11, so that the engaging effect between the TPA card cover unit 2 and the connector body 11 is better, and has the limiting and positioning effects.

[0051] The TPA card cover unit 2 further includes an insertion direction positioning slot 204 provided on the outer cover plate 202 .

[0052] In this embodiment, the role of the insertion direction positioning groove 204 is to prevent mistakes. Since there are positive and negative deviations in the structure of the TPA card cover unit 2, in order to reduce errors during the installation process and improve installation efficiency, the insertion direction positioning groove 204 is provided so that the TPA card cover unit 2 can identify the installation direction.

[0053] The distance L between the insertion plate 301 and the connector body 11 is 0.3 mm to 0.5 mm.

[0054] In this embodiment, a gap is left between the insertion plate 301 and the connector body 11 to facilitate the insertion of the pin, and the gap distance is optimally 0.3mm-0.5mm, which does not affect the structural stability and sealing, and facilitates the removal of the TPA card cover unit 2.
