The present invention relates generally to a wire connection terminal structure, and more particularly to a wire connection terminal structure, which can prevent the elastic abutment plate from permanent deformation when the conductive wire is plugged in by an improper angle so that the conductive wire can be reliably and effectively located without outward loosening or detachment.
There are many types of wire connection terminals applied to the circuit board for connecting with conductive wires.
The housing 2 is fitted around the terminal main body 10 to provide an insulation and protection effect. One end of the housing 2 is formed with a perforation 21 in alignment with the socket 102. Two lateral sides of the other end of the housing 2 are respectively formed with lateral notches 22 for the connecting sections 105 to pass through.
In use, an external conductive wire 4 is plugged through the perforation 21 and the socket 102 to extend between the two support legs 104. At this time, the conductive wire 4 will push the elastic abutment plate 103 outward. After the conductive wire 4 passes through the elastic abutment plate 103, the elastic abutment plate 103 will elastically restore to abut against the conductive wire 4 and tightly press the conductive wire 4 against the inner wall of the socket 102. Under such circumstance, the conductive wire 4 is prevented from outward loosening or detaching from the socket 102 under external extraction force.
However, in practice, during the process that an operator plugs the external conductive wire 4 through the perforation 21 into the socket 102, due to the factors of negligence, improper operation or judgment error of the operator, the operator often fails to plug the conductive wire 4 into the socket 102 by a correct (upright) and fixed angle. When the conductive wire 4 is obliquely plugged into the socket 102 in a direction to the elastic abutment plate 103 (as shown in
A solution to the above problem is to increase the depth or length of the perforation 21 of the housing 2 (or partially increase the height of one side of the perforation 21 distal from the elastic abutment plate 103) so as to prevent the conductive wire 4 from being plugged into the perforation 21 by an angle inclined from the axial direction of the socket 102. In this case, the conductive wire 4 can be guided and plugged into the socket 102 in a direction more approximate to the axial direction of the socket 102 to push and bias the elastic abutment plate 103. Accordingly, the elastic abutment plate 103 is prevented from being over-deformed so that the elastic abutment plate 103 can keep the ability to press the conductive wire 4. However, such structure will affect the appearance and size of the entire housing 2 and can hardly meet the requirement of a user (or a client).
Another solution to the above problem is to directly form a stop section on the terminal main body 10 or the housing 2 in the moving path of the elastic abutment plate 103 so as to restrict the lateral elastic deformation amount of the elastic abutment plate 103. Under such circumstance, the elastic abutment plate 103 is prevented from being over-biased with an excessively great elastic deformation amount (over the yield point) to cause permanent deformation. However, in practice, it is quite difficult to form the stop section and such design is not optimal.
It is therefore tried by the applicant to provide a wire connection terminal structure to solve the above problem.
It is therefore a primary object of the present invention to provide a wire connection terminal structure, which includes a terminal main body and a stopper member. One end of the terminal main body is formed with a connection section. The connection section defines a socket passing through the connection section. Two support legs extend from the connection section along the direction of the socket. An elastic abutment plate obliquely extends from the connection section between the two support legs. A locating section is disposed at one end of each support leg distal from the connection section. The stopper member is securely connected to the lateral sides of the two support legs via the locating sections. A stop face is formed on one side of one end of the stopper member proximal to the connection section and positioned in the moving path of the elastic abutment plate when elastically deformed. After the elastic abutment plate is forced, the deformation amount of the elastic abutment plate is restricted by the stopper face. Therefore, the elastic abutment plate is prevented from being over-deformed to cause permanent deformation. In this case, the elastic abutment plate can reliably and effectively elastically abut against the conductive wire plugged in the socket to prevent the conductive wire from outward loosening or detaching.
It is a further object of the present invention to provide the above wire connection terminal structure, in which the stopper member is securely connected with the ends of the two support legs distal from the connection section, whereby the stopper member cooperates with the connection section to enhance the structural strength of the entire terminal main body. In this case, when the conductive wire is plugged into the socket to apply an action force to the connection section, the swinging and unstable condition of the two support legs can be improved.
To achieve the above and other objects, the wire connection terminal structure of the present invention includes a terminal main body and a stopper member. One end of the terminal main body is formed with a connection section. Two support legs extend from two lateral sides of the connection section to the other end of the terminal main body in parallel to each other. The support legs are securely connected on a preset plane face. The connection section defines a socket passing through the connection section. An elastic abutment plate obliquely extends from an outer side of the connection section into a space between the two support legs. A locating section is disposed at one end of each support leg distal from the connection section. The locating section protrudes to a lateral side of the elastic abutment plate. The stopper member is securely connected to the lateral sides of the two support legs via the locating sections. A stop face is formed at one end of the stopper member proximal to the connection section. The stop face is directed to the two support legs and positioned in the moving path of the elastic abutment plate when elastically deformed. After the elastic abutment plate is forced, the deformation amount of the elastic abutment plate is restricted by the stopper face.
In the above wire connection terminal structure, the locating section is a protrusion structure. Each of two sides of the stopper member is formed with a recess corresponding to the locating section. The locating section passes through the recess and then transversely bends, whereby the stopper member is securely connected between the middles of the two support legs.
In the above wire connection terminal structure, a channel is formed on one face of the stopper member distal from the two support legs in communication with the two recesses, whereby the locating section passes through the recess and then bends to extend into the channel.
In the above wire connection terminal structure, a (protruding) back section is disposed on one face of the stopper member distal from the two support legs. The back section is positioned between the two recesses.
In the above wire connection terminal structure, a guide slope is formed at the middle of one face of the stopper member, which faces the socket.
In the above wire connection terminal structure, each support leg is formed with a connecting section outward bent from the support leg for connecting on the preset plane face.
In the above wire connection terminal structure, an insulation housing is fitted around the terminal main body. One end of the housing is formed with a perforation in alignment with the socket. Two lateral sides of the other end of the housing are formed with lateral notches for the support legs to pass through and outward extend.
In the above wire connection terminal structure, the terminal main body is made of a metal plate by means of punching and thereafter bending.
The present invention can be best understood through the following description and accompanying drawings, wherein:
Please refer to
The stopper member 3 is securely connected to the middle of the support leg 14 of the terminal main body via the locating section 16. In a preferred embodiment, each of two sides of the stopper member 3 is formed with a recess 311 corresponding to the locating section 16. In addition, a channel 31 is formed on one face of the stopper member 3 distal from the two support legs 14 in communication with the two recesses 311. The locating section 16 passes through the recess 311 and then transversely bends to extend into the channel 31, whereby the stopper member 3 is securely connected between the middles of the two support legs 14.
A stop face 32 is formed on one side of one end of the stopper member 3 proximal to the connection section 11 and directed to the socket 12. The stop face 32 is positioned in the moving path of the elastic abutment plate 13 when elastically deformed. In addition, a guide slope 33 is formed at the middle of one face of the stopper member 3, which faces the socket 12. The inclination direction of the guide slope 33 is approximately identical to the extending direction of the elastic abutment plate 13.
In a preferred embodiment, an insulation housing 2 is fitted around the terminal main body 1 as necessary. One end of the housing 2 is formed with a perforation 21 in alignment with the socket 12. Two lateral sides of the other end of the housing 2 are formed with lateral notches 22 for the support legs 14 to pass through and outward extend.

After the oblique conductive wire 4 passes through the elastic abutment plate 13, the conductive wire 4 will directly abut against the guide slope 33, whereby the guide slope 33 will guide the conductive wire 4 to further move downward to be located between the support legs 14 and the stopper member 3 and the terminal main body 1. At this time, the elastic abutment plate 13 will elastically restore to abut against the conductive wire 4 and tightly press the conductive wire 4 against the inner wall of the socket 12. Under such circumstance, the conductive wire 4 is securely held and located without easy loosening or detachment under external extraction force.
In the wire connection terminal structure of the present invention, the stopper member 3 is securely connected with the ends of the two support legs 14 distal from the connection section 11, (that is, proximal to the circuit board). Therefore, the stopper member 3 can enhance the structural strength between the two support legs 14. In this case, when the conductive wire 4 is plugged into the socket 12 to apply an action force to the connection section 11, the swinging and unstable condition of the two support legs 14 are reduced and improved.

In conclusion, the wire connection terminal structure of the present invention can truly prevent the elastic abutment plate from being over-deformed when the conductive wire is plugged in by an improper angle so that the conductive wire can be reliably and effectively located. The wire connection terminal structure of the present invention is inventive and advanced.
