a test lead with a banana plug comprises a lead and banana plugs arranged at two ends of the lead, wherein each banana plug comprises a wiring terminal connected with the lead through a metal connecting column, and an insulating inner shell and an insulating outer shell which are sequentially wrapped on the outer side of the wiring terminal, and a slit parallel to the axial direction of the wiring terminal is formed in the insulating outer shell;
the banana plug is equipped with the protective sheath with the junction of wire, and the protective sheath is including fixing the casing on the banana plug and setting up the spring in the casing, the spring housing is established on the wire, and the one end of spring is fixed on the banana plug, and the other end is fixed on the casing.
Furthermore, the slits are distributed along the upper end face and the lower end face of the insulating shell in a penetrating mode.
Further, the insulating inner shell and the insulating outer shell form a jack upwards along the wiring terminal.
Furthermore, the shell is made of elastic materials.
Further, the shell is made of silica gel.
Further, the insulating housing is made of PA66 nylon.
The utility model discloses beneficial effect:
1. the utility model discloses set up the protective sheath in banana plug and wire junction, be equipped with the cover in the protective sheath and establish the spring on the wire, when test wire junction takes place to buckle, the elasticity of spring can effectively cushion bending force and torsion, and then reduces the impaired phenomenon of junction wire, reduces the emergence of the test wire broken string condition.
2. The utility model discloses set banana plug to insulating casing and insulating inner shell parcel and live the terminal to set up the slit along insulating casing side height distribution on insulating casing, after the wire took place the broken string, can make single with the help of the light terminal of extracting the parcel of pliers, labour saving and time saving, the terminal received sufficient parcel dynamics when just having guaranteed test wire normal use.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 to 3, a test lead with a banana plug comprises a lead 5 and banana plugs 2 arranged at two ends of the lead 5, wherein the banana plug 2 comprises a terminal 1 connected with the lead 5 through a metal connecting post 201, and an insulating inner shell 202 and an insulating outer shell 203 wrapped outside the terminal 1 in sequence, a slit 204 parallel to the axial direction of the terminal 1 is formed in the insulating outer shell 203, in specific implementation, the insulating outer shell 203 can be made of PA66 nylon, the connecting post 201 and the terminal can be wrapped by the insulating inner shell 202 and the insulating outer shell 203, the opening size of the slit 204 can be as small as possible and can be controlled to be about 0.5mm, after the lead 5 is broken, due to the existence of the slit 204, the resistance of the insulating outer shell 203 when the terminal 1 is pulled out by external force is reduced, so that a single person can easily pull out the wrapped terminal 1 by means of pliers, and the binding post 1 is guaranteed to be wrapped by enough force when the test lead is normally used.
A protective sleeve 4 is arranged at the joint of the banana plug 2 and the lead 5, the protective sleeve 4 comprises a shell 401 fixed on the banana plug 2 and a spring 402 arranged in the shell 401, the spring 402 is sleeved on the lead 5, one end of the spring 402 is fixed on the banana plug 2, the other end is fixed on the shell 401, that is, the conducting wire 5 is arranged through the spring 402, when the test conducting wire is in use, the bending strength of the conducting wire 5 can be reduced at the connecting part of the conducting wire 5 and the banana plug 2 due to the existence of the spring 402, the torsion force when the conducting wire 5 is wound can be reduced, thereby reducing the occurrence of disconnection of the lead 5 at the connection point, and in the specific implementation, the housing 401 may be made of an elastic material, such as silicone, when the lead 5 is bent, the shell 401 can effectively play a role in buffering, so that the bending abrasion of the lead 5 is reduced, and the phenomenon that the lead 5 is broken at the connecting position is further reduced.
