Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a front view of the present invention assembled with a wire;
fig. 2 is a cross-sectional view taken along a-a of fig. 1 with the conductive lines removed.
The specific implementation mode is as follows:
referring to fig. 1, it is an embodiment of the present invention. Including connecting terminal 1, connecting terminal 1 installs in line seat inner chamber and can promote including line seat 11, awl 12, the axial that has the inner chamber awl 12 moves spring 13 in the inner chamber, be equipped with on the line seat and be used for laying and backstop the inlet wire hole seat 14 of awl, connecting terminal 1 front end has and is used for fixing connecting terminal at orbital installation department 15, installation department 15 can be the hole, also can be this technical field conventional technical means. The spring sleeve 2 is sleeved on the connecting terminal 1, and the spring sleeve 2 is in interference fit with the outer surface of the connecting terminal 1, so that the spring sleeve 2 can be prevented from falling off from the connecting terminal 1 to a certain degree. In order to better prevent falling off, the front end of the spring housing 1 is provided with an anti-falling device for preventing the spring housing 2 from falling off from the wiring terminal 1, the front end of the connecting terminal is provided with a fixing device matched with the anti-falling device, and the tail end of the spring housing extends out of the wire inlet seat end face 141.
Referring to fig. 1, the anti-slip means may be a bent portion 21 provided at the front end of the spring housing, and accordingly, the fixing means of the front end of the connection terminal is a hole 16 for receiving the bent portion. The hole 16 is a blind hole and is a concave hole to prevent water from leaking into the inside of the connection terminal. The bent portion may be in the shape of a hook, a straight hook, or a hook, and when the bent portion is in the shape of a hook, the inner shape of the hole 16 is matched with the hook, so that the spring housing can be better hung.
The retaining means may also be a snap ring (not shown) provided at a suitable position at the front end of the spring housing, and correspondingly the fixing means at the front end of the connection terminal is a fixing clip (not shown) that clips the ring. Of course, the two can be reversed, the anti-falling device can also be a fixed clasp, and the fixing device is a retaining ring. The retaining ring can be a closed ring or a semi-ring.
In order to enable the spring sleeve to be conveniently and quickly assembled into the connecting terminal 1, the diameter of the front part of the connecting terminal 1 is larger than that of the rear part of the connecting terminal 1, correspondingly, the diameter of the front part of the spring sleeve 2 is also larger than that of the rear part of the spring sleeve, the surfaces of the connecting terminal 1 and the spring sleeve 2 are in a step shape along the axial direction, when the spring sleeve is assembled, the front end of the spring sleeve 2 is sleeved into the rear end of the connecting terminal 1, and the spring sleeve is easily sleeved into the connecting terminal for assembly due to the fact that the inner diameter of the front end of the spring sleeve 2 is larger. The stepped transition of the surface of the connection terminal is preferably an inclined surface 17, so that the spring housing can be fitted more smoothly.
In order to facilitate the insertion of the conductor 3 into the connecting terminal 1, the rear end of the spring housing 2 is designed in the form of a bell-mouth 22, into which the conductor can be inserted smoothly. When the wire 3 is inserted, the insulation layer with a certain length at the wire connecting end is stripped according to the specified appointed length, the exposed wire is inserted into the wire inlet hole seat of the connecting terminal to complete the connection, the connected wire, and the spring sleeve 2 covers the wire 3 with the insulation layer close to the end face 141 of the wire inlet hole seat.
In order to ensure that the spring sleeve 2 can better protect the lead 3 close to the end face of the wire inlet hole seat, the diameter of the part, extending out of the end face of the wire inlet hole seat, of the spring sleeve is smaller than the diameter of the spring sleeve covering the rear part of the connecting terminal, and the corresponding part of the spring sleeve forms a step shape along the axial direction. The structure is based on the premise that the difference between the outer diameter of the lead and the inner diameter of the spring sleeve is as small as possible, but the lead can smoothly pass through the spring sleeve. Because the wire inlet hole seat at the rear part of the connecting terminal has a certain wall thickness, if the diameter of the spring sleeve sleeving the wire part is the same as that of the spring sleeve sleeving the rear part of the connecting terminal, a certain gap exists between the wire at the end face of the wire inlet hole seat and the spring sleeve along the radial direction, so that the wire at the end face of the wire inlet hole seat vibrates along with the gap when the rail vibrates, and the vibration absorption effect of the spring sleeve on the wire at the end face is reduced due to the existence of the gap. Therefore, the radial clearance between the spring sleeve and the lead is reduced, and the vibration absorption protection effect of the spring sleeve on the lead can be improved. Therefore, the step shape formed on the spring sleeve can reduce the gap between the spring sleeve 2 and the lead 3 along the radial direction, thereby improving the protection effect of the spring sleeve on the lead. Furthermore, the diameter of the spring sleeve 2 covering the wire 3 is smaller than the diameter of the spring sleeve covering the rear part of the connecting terminal, so that the spring covering the wire is sleeved on the end face 141 of the wire inlet seat to block the wall end 142 of the wire inlet seat, and thus the wire 3 is not blocked by the wall end 142 when entering the wire inlet seat 14, and the wire 3 can smoothly enter the wire inlet seat 14.
The higher the tight fit degree of the spring sleeve, the connecting terminal and the lead is, the better the vibration absorption effect of the spring sleeve can be. In view of this, when the wire 3 is installed on the connection terminal, the inner diameter of the spring housing extending out of the end face of the wire inlet hole seat is designed to be smaller than the outer diameter of the wire, so that the portion of the spring housing extending out of the end face of the wire inlet hole seat is in interference fit with the wire, where the outer diameter of the wire refers to the outer diameter of the wire with an insulating layer. During assembly, although the inner diameter of the spring sleeve is small, the insulating layer of the wire is soft, so the wire can be plugged into the spring sleeve in a rotating mode, the assembled wire forms interference fit with the spring sleeve, and the spring sleeve and the wire are connected into a whole due to the interference fit, so that the constraint force of the spring sleeve on the wire is enhanced, the vibration influence caused by the running track is effectively reduced, the collision and the friction between the wire and the end face of the wire inlet hole seat are reduced, and the protection of the spring sleeve on the wire is greatly improved.
The above embodiments do not limit the scope of the present invention, and those skilled in the art can make equivalent modifications and variations without departing from the overall concept of the present invention.
