To further clarify the explanation, and in order to provide a further understanding of the nature, operation and features of the invention, preferred embodiments are described and illustrated in the accompanying drawings:
referring to fig. 1A to 5, an electrical connector 2 of the present invention capable of electrically connecting ends of a plurality of wires 1 to each other, particularly referring to fig. 1A, 1B and 2, the electrical connector 2 of the present invention mainly includes three parts, namely a housing 3, a conductive member 4 and a lever 5.
Referring to fig. 1A, fig. 1B and fig. 2, the wire terminal 2 of the present invention has a wire inserting direction 20 for inserting the end of the wire 1 from the outside, and the housing 3 has a threading hole 30 correspondingly connected to the wire inserting direction 20, so that the end of the wire 1 can be inserted from the outside of the wire terminal 2 of the present invention and enter the inner accommodating space 31 of the housing 3.
The housing 3 is formed by correspondingly assembling a first housing 32 and a second housing 33 along the wire insertion direction 20, wherein a plurality of continuous and spaced second protruding points Q1 are formed on the surface of the first housing 32 corresponding to the extending positions and the number of the wire threading holes 30, and a plurality of continuous and spaced sliding slots 320 are sequentially formed between the plurality of second protruding points Q1 along the wire insertion direction 20, and a first protruding point P1 is formed on the surface of the second housing 33, and a plurality of pin-joint holes 330 capable of corresponding to the pin-joint activity of the shift lever 5 are formed in the second housing 33 along the wire insertion direction 20, and the positions and the number of the pin-joint holes 330 respectively correspond to the wire threading holes 30.
The conductive member 4 is installed in the accommodating space 31 inside the housing 3 and is composed of a conductive portion 40 and an elastic portion 41 correspondingly assembled to the conductive portion 40, in a preferred practical embodiment, the conductive portion 40 is integrally in a plate shape, the elastic portion 41 has a penetrating region 410 located on the extending path of the wire inserting direction 20, the penetrating region 410 is substantially perpendicular to the wire inserting direction 20, the penetrating region 410 has penetrating holes 4100 corresponding to the positions and the number of the wire threading holes 30, and after the electric wire 1 enters the wire threading hole 30 of the housing 3 and is inserted into the accommodating space 31, the penetrating holes 4100 enable the end section of the electric wire 1 to be further inserted into and pass through the conductive member 4.
In addition, two sides of the penetrating region 410 of the conductive member 4 respectively extend out of an assembling region 411 and an elastic energy releasing region 412 in a direction substantially parallel to the plug wire direction 20, in a preferred embodiment, the assembling region 411 can correspondingly assemble the conductive member 40 inside the conductive member 4 in a clamping manner, the elastic energy releasing region 412 is formed in a bent semi-tubular shape (which can be regarded as a U shape or a V shape) by an elastic material, and a plurality of third bumps 42 are disposed on the surface of the elastic energy releasing region 412 adjacent to the electric wire 1.
After the end of the electric wire 1 is inserted into the accommodating space 31, the elastic energy releasing area 412 is pressed to reduce the opening angle of the bending state, and meanwhile, the two corresponding sides of the end of the electric wire 1 are respectively clamped and positioned by the assembling area 411 and the elastic energy releasing area 412, and then the end of the electric wire 1 continuously passes through the through hole 4100.
In addition, as shown in fig. 1A to fig. 3A, the shift lever 5 has an operation portion for being contacted by a hand of a person, the operating part is adjacent to the surface of the housing 3 to form a slot P2, the slots P2 are designed to be respectively corresponding to the positions of the first salient points P1, so that the slot P2 of the lever 5 can be correspondingly clamped with the first salient point P1 of the housing 3, accordingly, the lever 5 is clamped with the surface of the housing 3 at a first position 50 in the state that the electric wire connector 2 of the present invention is not used, the first bump P1 and the slot P2 jointly form a first positioning mechanism P of the first position 50, while providing a human hand with the perception that the shift lever 5 is actually clamped and positioned on the surface of the shell 3, without applying too much force to the shift lever 5 or eliminating the psychological uncertainty that the shift lever 5 has a chance to move away from the current position.
Referring to fig. 1A to 3B, two sliding rods Q3 are extended from one side of the manipulating portion, two sliding rods Q3 are located at corresponding positions, a clamping portion Q2 is located between the manipulating portion and the sliding rod Q3 of the shift lever 5, a pressing portion P3 is located at the tail end of the sliding rod Q3, the direction of the pressing portion P3 is set to be a direction intersecting the sliding rod Q3, a plurality of pivot shafts located at corresponding positions are located inside a surface where the two sliding rods Q3 abut against each other, and the pivot shafts of the shift lever 5 are respectively pivoted to the pivot holes 330 of the housing 3, so that the shift lever 5 can swing back and forth relative to the housing 3.
In a preferred embodiment, the width of the sliding bar Q3 is designed to be gradually widened from the end connected to the operating portion, the width of the pressing portion P3 is designed to be a minimum width of the sliding bar Q3, and the portion of the sliding bar Q3 close to the pressing portion P3 is designed to be an arc-shaped pattern while the width is designed to be a maximum width.
Referring to fig. 1A to 3C, during the swinging displacement of the shift lever 5, it is easy to find that the shift lever 5 gradually moves to a position where the partial range of the sliding rod Q3 with the maximum width contacts the elastic energy releasing region 412 of the conductive member 4 (as shown in fig. 3B) in a state where the partial range of the sliding rod Q3 with the maximum width does not contact the elastic part 41 of the conductive member 4, and since the partial range of the sliding rod Q3 of the shift lever 5 close to the pressing part P3 is set to be in an arc shape, a hand of a person can clearly sense the hand feeling that the shift lever 5 does not contact the conductive member 4, the hand feeling that the shift lever 5 starts to contact the conductive member 4, and the hand feeling that the shift lever 5 continuously presses the conductive member 4.
The sliding rod Q3 connected to the shift lever 5 is pushed into the sliding slot 320 of the first casing 32 by a human hand, the sliding rod Q3 continuously slides into the sliding slot 320 until the engaging portion Q2 of the shift lever 5 is engaged with the second protruding point Q1 of the first casing 32 correspondingly (as shown in fig. 3C), so that the shift lever 5 is sensed by a human hand to be pushed to the bottom without applying force, and accordingly, the shift lever 5 can be abutted against the surface of the housing 3 at the second position 51 under two states of the wire connector 2 of the present invention ready for the insertion of the wire 1 or the insertion of the wire 1, and the engaging portion Q2 of the shift lever 5 and the second protruding point Q1 of the first casing 32 jointly form the second positioning mechanism Q at the second position 51.
In addition, referring to fig. 3C, in order to further stably clamp the electric wire 1 when the electric wire is inserted into the electric wire connector 2 of the present invention, the second positioning mechanism Q of the present invention further includes a third bump 42 corresponding to the bottom pressing portion P3 of the shift lever 5 and clamped against the elastic energy releasing area 412 of the elastic portion 41 of the conductive member 4, and the second positioning mechanism Q of the second position 51 is jointly formed by the bottom pressing portion P3 and the third bump 42, so as to prevent the shift lever 5 from displacing and changing the original positioning position under the conditions of collision of external force or slipping and falling off of the electric wire 1, and to greatly reduce the falling off of the electric wire 1 from the electric wire connector 2 of the present invention, and to provide a hand feeling and a sense of feeling that the shift lever 5 is surely clamped against the conductive member 4.
Referring to fig. 4 and 5, it can be seen from the above detailed description that the relative distribution positions of the electric wire 1 with respect to other components in the electric wire connector 2 when the electric wire 1 is actually inserted into the electric wire connector 2 of the present invention, the electric wire connector 2 of the present invention can be designed to stably position the shift lever 5 at the first position 50 where the electric wire 1 is not inserted and the second position 51 where the electric wire 1 is inserted respectively through the first positioning mechanism P and the second positioning mechanism Q which are mutually matched on the housing 3, the conductive member 4 and the shift lever 5, and two kinds of positioning mechanisms are designed to be positioned on the path of the movement displacement of the shift lever 5, so as to simplify the step of inserting and positioning the end of the electric wire 1 and the ease of manual force application, thereby not only reducing the equipment cost used in the assembly process between the conductive structural components and the corresponding assembly process, meanwhile, the simplicity of field construction assembly, line coordination or wire repairing can be improved.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
