Description
Technical Field
The present invention relates to an improved structure of a rail clip for a rail terminal, and more particularly, to a rail clip structure with improved structural strength and operation stability.
Background
It is a widely used technical means to apply a metal component (or called conductive component) and a spring conductor (or called metal spring) which are covered in an insulating casing (usually made of plastic material) to press or connect the wires entering the terminal, so as to form an operation mechanism for electrically connecting or releasing the wires, and thereby control the state of the wires and a default grounding rail connected to the ground.
As shown in fig. 1 and 2, a typical conventional track terminal structure using the above technical means is disclosed, in which a grounding assembly 4 is accommodated in a housing 3, a wire inlet 31 and an operation hole 32 for inserting a wire are disposed on the housing 3, a pushing member 321 is disposed in the operation hole 32, a tool can be inserted into the operation hole 32 to operate the pushing member 321, so as to link an internal conductive assembly 5 to assist the wire to be connected or separated with the grounding assembly 4 in the wire inlet 31, a first section 41 and a second section 42 having elasticity respectively extend from two sides of the grounding assembly 4, an elastic clamping mechanism of a pair of preset grounding tracks (not shown) is formed between the first section 41 and the second section 42, and a hook-shaped tail section 43 is formed at an extending end of the first section 41; the housing 3 is provided with a lower portion 33 corresponding to the outer side of the first section 41, a slot 35 for accommodating the tail section 43 is provided on the inner side of the lower portion 33 (the side close to the first section 41), a hook-shaped foot region 34 extends outwardly from the outer side of the lower portion 33 (the side away from the first section 41), a slot 36 with one side open to the outside is formed between the foot region 34 and the outer side surface of the lower portion 33, so that a tool (such as a screwdriver) can extend into and stretch the foot region 34 and the lower portion 33 outwardly, and the tail section 43 is linked by the slot 35, so that the first section 41 and the second section 42 of the grounding assembly 4 can be expanded mutually, so that the grounding assembly 4 can perform the action of clamping or releasing the grounding rail.
However, in the above-mentioned structure, since the housing 3 is designed to have the opening 361 with one side opened to the outside (for demolding) in consideration of the convenience of the production process (one-way demolding), the foot portion 34 and the outer side surface of the lower portion 33 are connected only by one side, so that the tool (a line driver) is easily slipped out from the opening 361 of the housing 36 by the elastic expansion, resulting in the loss of application; in addition, the overall strength of the structure is not good, so that in practical application, when a tool (a straight screwdriver) is inserted into the slot 36 to apply a force, the side of the slot 36 having the opening 361 is easy to deform due to the poor structural strength, so that the opening 361 is elastically expanded, and the foot region 34 is easy to distort or damage due to improper operation or long-term use.
In order to improve the above disadvantages, some related manufacturers use 3D printing process technology to produce the housing 3, and by such a process method without mold forming, a recessed slot with an upper opening is directly formed between the foot region 34 and the outer side surface of the lower portion 33 of the housing 3, and the recessed slot has mutually connected portions corresponding to both sides of the foot region 34 and the outer side surface of the lower portion 33, so that not only the structural strength of the peripheral side of the recessed slot is increased, but also the foot region 34 is prevented from deforming and damaging after being stressed, and when a tool (a word driver) is inserted into the recessed slot for force application operation, the tool (the word driver) is not easy to slip out of the recessed slot, and the above application disadvantages can be effectively improved; however, the processing method of 3D printing is time consuming, difficult to mass-produce, and expensive in overall processing cost, and thus, the economic benefit of production is not met for the track terminal product.
Because the rail clip structure of the rail terminal in the prior art has the above-mentioned shortcomings, the present invention has been developed after the inventor has studied and improved the above-mentioned shortcomings.
