Problems solved by technology

[0003] In the existing rectangular low-voltage connector, when the terminal is inserted, because the depth of the lock hole of the secondary lock is too large, its hanging point is easy to exceed the elastic hook, so that the crimping part of the terminal is stuck by the elastic hook. Come on, the terminal will no longer be able to move back. When the secondary lock is pressed, the terminal will be forcibly pressed down, resulting in damage to the elastic hook; if the hook is damaged, the terminal needs to be disassembled and replaced. Frequent disassembly and assembly of the terminal may cause Damage to the gasket, resulting in a decrease in the waterproof function, the depth stroke of the lock hole of the secondary lock has no limit function, and it will also cause the need to be very careful when inserting the terminal, so that the crimping part of the terminal cannot be stuck on the positioning elastic hook In this way, the overall efficiency will be low, and there will be continuous rework

Embodiment 1

[0060] Step 1: Put the smooth side of the sealing gasket 4 downward into the lower end wall 7 of the plug sheath 1;

[0061] Step 2: Fasten the back cover 5 on the lower end wall 7 of the plug sheath 1, the card edge 25 of the back cover 5 can be stuck on the lower end wall 7, when pressing down to install the back cover 5, ensure that the back cover 5 There is a limit when pressing down, and the third lock hook 26 on the back cover 5 is locked in the rectangular through-hole lock groove 17 from the inner side of the lower end wall 7 to ensure the stable installation of the back cover 5;

[0062] Step 3: Install the sealing ring 3 between the outer wall 8 and the upper end wall 9 of the plug sheath 1;

[0063] Step 4: If image 3 , 6 As shown in -7, first install the secondary lock 2 into the upper end wall 9 of the plug sheath 1 along the high side plate 13, and the lower part of the fan-shaped sheath boss 20 will be set on the outside of the low side plate 14, At this tim...

Embodiment 2

[0068] If the terminal 6 is damaged and needs to be repaired, you can use force on the fan-shaped sheath boss 20 to facilitate the extraction of the secondary lock 23 from the secondary lock groove 16, so that the secondary lock 2 can be slowly pulled out to the first position. In the step-locked state, gently pry the limit retaining ear 22, so that the primary locking hook 15 can be separated from the primary anti-locking hook, thereby taking out the secondary locking part 2 from the upper end wall 9 of the plug sheath 1, and then using a fine iron Pick up the positioning elastic hook 12 of the terminal 6 to be replaced with a stick, and then slowly remove the terminal 6 from the entire connector by pulling the wire. If the terminal 6 can smoothly enter the corresponding second locking hole 18, then insert the good terminal 6 to be replaced into the corresponding hole, if other good terminals 6 cannot smoothly enter the corresponding second locking hole 18 If it still fails a...

Abstract

The invention discloses a rectangular low-voltage connector, which comprises a plug sheath, a secondary locking part, a sealing ring, a sealing gasket, a rear cover and a plurality of terminals. The plug sheath is composed of a kidney-shaped lower end wall, a kidney-shaped outer side wall and a kidney-shaped upper end wall, a terminal locking plate is arranged in the plug sheath, a plurality of first locking holes are formed in the terminal locking plate, and the upper end wall is composed of a high side plate, a low side plate and primary locking hooks; the secondary lock part is provided with a primary back lock buckle, a limiting stop lug, two secondary lock catches and a plurality of second lock holes; the rear cover is provided with a plurality of through holes, a clamping edge and athird lock hook; a plurality of convex holes are formed in the sealing gasket; each terminal comprises a plug part, a hanging point part and a wire pressing part from top to bottom in sequence. The rear cover is arranged on the lower end wall of the plug sheath, the secondary locking part is arranged in the upper end wall of the plug sheath, and the terminal with the pressed wire is inserted intothe plug sheath. By utilizing the stroke height of the second locking hole in the secondary locking part, after the terminal is inserted, the positioning elastic hook of the terminal is just located at the hanging point part of the terminal.

Description

technical field [0001] The invention belongs to the technical field of low-voltage connectors, in particular, the invention relates to a rectangular low-voltage connector and an installation method thereof. Background technique [0002] Existing electrical connectors are generally pin connectors, and generally have a body, conductive terminals accommodated in the body, and a shell sleeved outside the body. Wherein the body has a receiving space for receiving the contact portion of the conductive terminal and the docking pin that is docked with the contact portion. [0003] In the existing rectangular low-voltage connector, when the terminal is inserted, because the depth of the lock hole of the secondary lock is too large, its hanging point is easy to exceed the elastic hook, so that the crimping part of the terminal is stuck by the elastic hook. Come on, the terminal will no longer be able to move back. When the secondary lock is pressed, the terminal will be forcibly pres...
