Anti-loose bolt connection structure for junction box

A method of forming an anti-loose connection structure for a junction box, comprising:

• providing a junction box main body, wherein the junction box main body includes a first terminal having a threaded hole;
• providing a second terminal for electrically connecting to the first terminal, the second terminal including a through hole;
• aligning the through hole with the threaded hole;
• inserting a bolt through the through hole;
• rotating a bolt head portion of the bolt to threadedly connect the bolt to the first terminal via the threaded hole;
• providing an anti-loose assembly, wherein the anti-loose assembly is configured to engage the bolt head portion of the bolt;
• and
• connecting the anti-loose assembly to the junction box main body such that the anti-loose assembly prevents rotation of the bolt head portion relative to the junction box main body, wherein the anti-loose assembly includes a plate having a bolt locking hole adapted to a shape of the bolt head portion.

An anti-loose bolt connection structure for a junction box, comprising:

• a junction box main body;
• a first terminal disposed on the junction box main body, the first terminal being provided with a threaded hole;
• a second terminal for electrically connecting to the first terminal, the second terminal being provided with a through hole;
• a bolt having a bolt head portion;
• and
• an anti-loose assembly mounted on the junction box main body, the anti-loose assembly being cooperatively mounted with the bolt head portion for limiting rotation of the bolt, wherein the bolt head portion has a through hole, wherein the anti-loose assembly includes a locking pin, the locking pin extending into the through hole to prevent rotation of the bolt.
