Connection structure
View Patent ↗In a connection structure, electric wire includes an inclined sheath section between an exposed core wire section and a whole circumferential sheath section. In the inclined sheath section, an end surface of the insulating sheath on one end side in a longitudinal direction inclines in a direction intersecting the longitudinal direction and thereby a portion of the core wire is exposed. Each of crimping pieces of a terminal has a core wire crimping section that crimps the exposed core wire section, a whole circumferential sheath crimping section that crimps the whole circumferential sheath section, and an inclined sheath crimping section that crimps the inclined sheath section. The terminal is crimped to the electric wire so that the end surface of the inclined sheath section faces a base plate section of the terminal.
1. An electrical connection structure, comprising an electric wire having a core wire and an insulating sheath that covers an outer circumferential surface of the core wire, and a terminal crimped to a terminal section of the electric wire on one end side in a longitudinal direction,
wherein the electric wire includes:
an exposed core wire section in which a whole outer circumferential surface of the core wire is exposed to the terminal section from the insulating sheath;
an entire circumferential sheath section in which the outer circumferential surface of the core wire is covered with the insulating sheath; and
an inclined sheath section that is formed between the exposed core wire section and the entire circumferential sheath section,
wherein the inclined sheath section continues to the entire circumferential sheath section,
wherein, in the inclined sheath section, an end surface of the insulating sheath on one end side in the longitudinal direction inclines in a direction intersecting the longitudinal direction and thereby a portion of the core wire is exposed,
wherein the terminal includes a connection section that is electrically connected to a mating terminal, a base plate section that is provided continuously with the connection section, and a pair of crimping pieces that extend upwardly from both side edges of the base plate section, respectively,
wherein each of the crimping pieces has a core wire crimping section that crimps the exposed core wire section, an entire circumferential sheath crimping section that crimps the entire circumferential sheath section, and an inclined sheath crimping section that crimps the inclined sheath section, and
wherein the terminal is crimped to the electric wire so that the end surface of the inclined sheath section faces the base plate section.
2. The connection structure according to the claim 1 , wherein a portion of the insulating sheath of the inclined sheath section is crimped to the core wire crimping sections.
3. The connection structure according to the claim 1 , wherein the core wire crimping section and the inclined sheath crimping section of each of the crimping pieces are partitioned by a slit that extends toward the base plate section from a tip of the crimping piece in an erection direction thereof.
4. The connection structure according to the claim 1 , wherein waterproofing sections extending toward the connection section are formed at end portions of the core wire crimping sections on the connection section side.
