Wire-grasping structure for terminal block
A wire-grasping structure for a terminal block is disclosed. The wire-grasping structure includes a core, a conductive terminal piece and a screw. The core is transversely formed with a socket and vertically formed with a threaded hole. The socket and the threaded hole are communicated mutually and each communicated with the exterior of the core. The conductive terminal piece has a receiving portion and a terminal portion. The terminal portion is configured to be horizontally inserted into the socket such that the receiving portion projects from the core terminal portion. The screw is configured to be vertically screwed in to the threaded hole and enter the socket to abut against the terminal portion. Thereby, the wire-grasping structure can store a jumper bar and facilitate convenient use.
1. A wire-grasping structure for a terminal block, the wire-grasping structure comprising:
a core that is transversely formed with a socket and vertically formed with a threaded hole, wherein the socket and the threaded hole are communicated mutually and each communicated with an exterior of the core;
a conductive terminal piece that comprises a receiving portion and a terminal portion, wherein the terminal portion is configured to be horizontally inserted into the socket such that the receiving portion projects from the core; and
a screw that is configured to be vertically screwed into the threaded hole and enter the socket to abut against the terminal portion of the conductive terminal piece,
wherein the receiving portion includes two openings, not communicating with each other, configured to be inserted by two pins of a jumper bar, respectively, so as to rest the jumper bar.
2. The wire-grasping structure of claim 1 , further comprising a base that is vertically formed with an accommodating space and a through hole, and transversely formed with a window, wherein the accommodating space, the through hole and the window are communicated with one another and each communicated with an exterior of the base, in which the core is configured to be received in the accommodating space such that the socket is aligned and communicated with the window and the threaded hole is aligned and communicated with the through hole, thereby allowing the screw to be vertically screwed into the threaded hole through the through hole.
3. The wire-grasping structure of claim 2 , wherein the base comprises a shoulder that is adjacent to the accommodating space and is for the conductive terminal piece to rest thereupon.
4. The wire-grasping structure of claim 1 , wherein the two openings are two closed openings that are independent of each other.
5. The wire-grasping structure of claim 1 , further comprising a base structure accommodating the core, the screw and the conductive terminal piece, wherein the base structure has a top surface, and the receiving portion has a shoulder resting on the top surface of the base structure; and wherein the two openings are exposed outside the base structure, and in their entirety, above the top surface of the base structure.
