Description

[Detailed description of the invention] [Industrial field of application] The present invention covers the exposed end of an insulated wire with a sleeve to ensure that the connected live parts are covered in the center without causing positional shift. This relates to a protective sleeve cover.

[Conventional technology]

Hitherto, various types of sleeve covers of this kind have been known. For example, the sleeve cover of Utility Model Application No. 58-67162, invented by the applicant, is a cylindrical housing with an inner diameter that can accommodate the live part. a receiving side member formed by providing a gripping cylinder having an inner diameter matching the diameter of the electric wire through a tapered part at one end of the part, and a receiving side member formed by providing a gripping cylinder having an inner diameter that matches the diameter of the electric wire through a tapered part at one end of the fitting cylinder that can be inserted into the housing part; An insertion side member provided with a gripping cylinder having the same shape as the gripping cylinder is formed, and both ends of the sleeve of the charging part accommodated in the housing part are connected to each tapered part provided on the receiving side member and the insertion side member. I'm trying to block it.

[Problem that the invention attempts to solve]

However, the invention of the above-mentioned application, which was invented by the applicant, has a structure in which the charging part is held suspended in the housing part, which is often seen in the past.
Since the tapered parts provided on the receiving side member and the insertion side member block both ends of the live part, when a strong impact is applied, the ends of the live part will not bite into the tapered parts. This may cause misalignment, or the end of the live part may protrude from the sleeve cover, making it impossible to reliably cover and protect the center of the live part.

[Means for solving problems]

By providing a plurality of notches at one end of the cylindrical body, the outer diameter of which can be inserted into the housing portion of the receiving side member and the insertion portion of the insertion side member, and the inner diameter of which can be inserted into the insertion portion of the receiving side member, the resilient piece can be formed. A stopper having a portion formed thereon is loaded into at least one of the receiving side member and the insertion side member.

[Effect]

With one end of the stopper loaded on the receiving side member and the insertion side member hitting the tapered part, the tip of the elastic piece that is attached to the other end of the stopper is pressed against the end surface of the sleeve that covers the live part. In this abutting state, the elastic force of the elastic piece prevents it from coming off the sleeve, so the receiving side member and the insertion side member are not allowed to slide, and the live part is not removed from the sleeve cover. Make sure it is fixed in the center position.

〔Example〕

In the figure, 1 is a receiving side member formed of a synthetic resin material, and the receiving side member 1 includes an insulated wire A,
A cylindrical accommodating part capable of accommodating a live part E, in which conductors C and C' from which the insulation coating B of A' has been peeled are butted against each other, and a copper pipe sleeve D is applied and tightened to the surface of the conductors C and C'. At the same time, an insulated wire A is formed at one end of the accommodating part E via a tapered part 3a.
It is formed by extending the grip cylinder 4a. The inner diameter of the gripping tube 4a is formed into a tapered surface so that the diameter gradually becomes smaller toward the tip, and a plurality of steeply tapered stepped portions 5a are provided at appropriate intervals near the tip, and the stepped portions 5a are provided on the outer circumferential surface. A plurality of reinforcing ribs 6a are provided at intermediate positions. Reference numeral 7 is made of a synthetic resin material and has a tapered part 3b and a gripping cylinder 4b having the same shape as the receiving side member 1 extending from one end of a fitting cylinder 8 formed to have an outer diameter that can be fitted into the housing part 2. This is an insertion side member, and a flange portion 9 is provided around the inner end of the insertion tube 8. A receiving side member 1 is attached to the grip cylinder 4b.
A plurality of step portions 5b are provided symmetrically on the inside, and a plurality of reinforcing ribs 6b are provided on the outer peripheral surface. Also,
By providing a chevron-shaped protrusion 10 around the outer circumferential surface of the insertion tube 8, the protrusion 10 is configured to bite into the inner circumferential surface of the accommodating portion 2. Furthermore, each grip cylinder 4a, 4
As shown in FIG. 1, between reinforcing ribs 6a or 6b adjacent to the outer circumferential surface of b, a numerical value 11 of the inner diameter dimension at that part is indicated, and an insulated wire A to be inserted,
Match the outer diameter dimension of A' with this value 11 and cut it at the outer position of the reinforcing rib 6a.

Reference numeral 12 denotes a stopper that is loaded into the housing portion 2 of the receiving side member 1 and the fitting tube 8 of the insertion side member 7. This stopper 12 has an outer diameter that can be inserted into the accommodating portion 2 and the fitting tube 8, and an inner diameter that allows the insulated wire A,
A' is a cylindrical body large enough to be inserted through, and a plurality of notches 13 are provided at equal intervals on one end of the cylindrical body, thereby forming the resilient piece portion 14.

Next, the use of the sleeve cover of the present invention will be explained. First, place the stopper 12 on the receiving side member 1.
The accommodating part 2 and the insertion tube 8 of the insertion side member 7 are pushed and loaded, and these are inserted into the insulated wires A and A', respectively, and the insulation coating B is applied to the end of each of the wires A and A'. The conductive wires C and C' are peeled off over a required length to expose the respective conductive wires C and C', and a copper tube sleeve D is fitted between the ends of the conductive wires D to butt against each other, and the live portion E is formed by tightening and fixing.

Then, when the receiving member 1 is slid toward the tip of the insulated wire A, the stopper 12 is pushed into the accommodating portion 2 and the tip of the resilient piece portion 14 is pushed into the copper pipe sleeve D.
At the same time, the other end of the stopper 12 hits the tapered portion 3a, thereby fixing the receiving member 1. In this state, hold the receiving member 1, slide the insertion member 7 toward the tip of the insulated wire A', and press it until the collar 9 comes into contact with the tip of the accommodating portion 2, then the stopper 12 is pushed into the insertion tube 8, and the tip of the elastic piece 14 hits the end face of the copper tube sleeve D, and the other end of the stopper 12 hits the tapered part 3b, fixing the insertion side member 7. . The receiving side member 1 and the insertion side member 7 are connected to each other by a protrusion 10 provided around the fitting tube 8 biting into the inner circumferential surface of the accommodating portion 2, thereby making the fitting between the two strong. Make the connection difficult to disconnect.

Further, the stopper 12 is not limited to the one that is loaded on both the receiving side member 1 and the insertion side member 7 as in the above embodiment, but, for example, as shown in FIG. If the receiving side member 1 is fixed by using the stopper 12, the purpose of the invention can be achieved without necessarily loading the stopper 12 on the insertion side member 7.

Furthermore, if the stopper 12 is formed with a protrusion 15 around its outer surface, the protrusion 15 will bite into the inner circumferential surface of the housing portion 2 or the fitting tube 8 during use, and the stopper 12 itself will become strong. Thus, the receiving side member 1 and the insertion side member 7 can be fixed even more reliably.

[Effect of idea]

As described above, when the sleeve cover of the present invention is used, one end of the stopper loaded in at least one of the receiving side member and the insertion side member is connected to a taper provided inside the receiving side member and the insertion side member. By abutting the tip of the resilient piece provided at the other end of the stopper against the end surface of the sleeve while the sleeve cover is in abutment with the stopper, the sleeve cover is fixed extremely firmly and can withstand even strong impacts. The receiving side member and the insertion side member do not slide individually, and the charging portion can be reliably covered and protected at the center position of the sleeve cover.
