Detailed Description
A U-shaped contact pin connector comprises contact pins 1, a plastic piece 2, a rubber shell 3 and a terminal wiring harness 4, the plastic shell 3 is inserted into the plastic part 2, the contact pin 1 is inserted into the plastic part 2 from one end far away from the plastic shell 3, the terminal wire harness 4 is inserted into the plastic shell 3 from one end far away from the plastic part 2, the inner end of the contact pin 1 is connected with the terminal 4-1 at the inner end of the terminal wire harness 4 in an inserting manner, the contact pin 1 comprises an inner contact pin 1-1 and an outer contact pin 1-2 which are integrally formed, the inner contact pin 1-1 is inserted into the terminal pin hole 4-2 of the terminal 4-1 after being inserted into the plastic part 2, the outer contact pin 1-2 is inserted into the outer insertion groove 2-1 of the plastic part 2, the inner side wall of the plastic part 2 is provided with a plastic part inner guide groove 2-2, and the outer wall of the plastic shell 3 is integrally formed with a plastic shell guide rib 3-1 matched with the plastic part inner guide groove 2-2.
As shown in fig. 1, the contact pin 1 is formed in a U-shaped structure by designing an inner pin 1-1 and an outer pin 1-2. During assembly, the terminal wiring harness 4 is inserted into the plastic shell 3, the contact pin 1 is inserted into the plastic part 2, the plastic shell 3 with the terminal wiring harness 4 is inserted into the plastic part 2 with the contact pin 1, and after the plastic shell 3 with the terminal wiring harness 4 is inserted, the inner contact pin 1-1 on the contact pin 1 is inserted into the terminal pin hole 4-2 of the terminal 4-1, so that the contact pin 1 is communicated with the terminal 4-1 of the terminal wiring harness 4.
The outer wall of the rubber shell 3 is integrally provided with a rubber shell non-return bulge 3-2, and the inner side wall of the plastic part 2 is provided with a plastic part buckle inner step 2-3 matched with the rubber shell non-return bulge 3-2. After the rubber shell 3 is spliced with the plastic part 2, the non-return bulge 3-2 of the rubber shell is clamped into the inner step 2-3 of the plastic part buckle, so that the rubber shell and the plastic part are fixed.
