Description

Technical Field

[0001] This utility model relates to a wire connection terminal assembly structure, and more particularly to a wire connection terminal structure that can prevent insufficient structural strength and reduced conductivity caused by material stretching, and can guide the smooth movement of the metal spring to avoid skewness and loosening under force. Background Technology

[0002] Taiwan Patent Publication No. M611988 discloses an improved structure for a conductive component of a wire connection terminal, which mainly includes: a housing and a body disposed in the housing. The body has at least one opening for receiving a metal spring. One edge of the opening has a recess, and the other edges are formed into a limiting portion by deep drawing. The limiting portion has first and second sidewalls adjacent to the recess, and an end wall opposite to the recess. The metal spring has a curved section in the middle and a first section and a second section near both ends, respectively. The first section has a neck for engaging and positioning in the recess, so that the second section can extend toward the end wall and form a mechanism for elastically clamping the wire.

[0003] In addition to regulating the movement path of the second segment when the metal spring moves to prevent the metal spring from tilting to the sides under force, the first and second sidewalls can also limit the tilting of the wire to the sides when the wire is inserted and clamped between the second segment of the metal spring and the end wall of the opening. If it is necessary to straighten the wire outside the housing (adjust the direction of the wire or bend the wire) and pull it, or if vibration is generated due to mechanical operation, the first and second sidewalls can restrict the wire from tilting to the sides. This can prevent the clamping of the metal spring and the edge of the opening from loosening or being insecure, which would affect the conductivity and reduce the possibility of the wire coming off outward.

[0004] However, since the limiting part is formed by stretching the material around the opening through a deep drawing process, the material at the corner of the opening is gradually thinned during the deep drawing process. This not only affects the structural strength of the limiting part, but also reduces its electrical conductivity and heat dissipation, and may even cause the limiting part to crack or be damaged. In addition, during production planning, the spacing between the stamping dies must be increased to provide the space required for the material around the opening to stretch and deform, which also generates more waste and is not economically efficient.

[0005] In view of the above-mentioned shortcomings of conventional terminal conductive component structures, the inventors researched ways to improve these shortcomings, and finally this utility model was produced. Utility Model Content

[0056] Please refer to Figures 1 to 4 As shown, the structure of the first embodiment of this utility model includes: a first terminal unit A1 composed of a terminal assembly 1 and a terminal base 2; wherein the terminal assembly 1 has a conductive terminal 11 and a metal spring 12, the conductive terminal 11 has a bent portion in the middle section, so that a base 111 and a contact portion 115 are formed near both ends respectively, the base 111 is provided with a hollow opening 112 and a side portion 117 adjacent to the opening 112, the side edge of the opening 112 near the contact portion 115 is formed into an end wall 113 by a breaking bending method, and the end wall 113 extends from the edge of the opening 112 by bending; a positioning portion 114 (which may be a groove) is provided on the side of the opening 112 away from the end wall 113, and the base 111 is provided with a lower edge 1111 below the side portions 117 on both sides of the opening 112 respectively.

[0057] The metal spring 12 has a curved section 121 in the middle. One end of the metal spring 12 has a positioning section 122, which can be combined with the positioning section 114 to form a positioning. The other end of the metal spring 12 extends obliquely into the opening 112 towards the side away from the positioning section 114 to form a movable and elastic locking end 123. The locking end 123 can cooperate with the end wall 113 to form an elastic clamping mechanism.

[0058] The terminal block 2 has a recessed accommodating space 21 on one side surface to accommodate the terminal assembly 1. The accommodating space 21 has a protrusion 26 and a positioning post 213. An upper edge 261 is provided on the top edge of the protrusion 26. The accommodating space 21 has a wire insertion hole 22, an operation hole 23 and at least one channel portion communicating with the outside. The terminal block 2 has a plurality of connecting portions 24 on the side facing the accommodating space 21. The first terminal unit A1 is also provided with a side cover 20. The side cover 20 has a connected portion 201 corresponding to each of the connecting portions 24 and a sub-protrusion 202 corresponding to the protrusion 26. An upper edge 203 is provided on the top edge of the sub-protrusion 202.

[0059] In this embodiment, the channel portion includes a first channel 211 provided beside the accommodating space 21 corresponding to the connecting foot portion 115, so that the connecting foot portion 115 can extend out of the terminal block 2 through the first channel 211; the wire jack 22 extends to a position between the outer edge of the clamping end 123 of the metal elastic piece 12 and the end wall 113, and the operation hole 23 extends to a position between the clamping end 123 and the arc-shaped portion 121.

[0060] When the terminal assembly 1 is combined in the accommodating space 21, the convex portion 26 can extend into the lower side beside the side portion 117 of the base portion 111, and the upper edge 261 supports the lower edge 1111 of the base portion 111, and the positioning column 213 can be combined (or blocked) in the arc-shaped portion 121 of the metal elastic piece 12 to prevent slipping; then, the side cover 20 is assembled to the combining portion 24 of the terminal block 2 by the combining portion 201, and can be covered and fixed on the accommodating space 21, so that the auxiliary convex portion 202 can extend into the lower side of the side portion 117 on the other side of the base portion 111, and the upper edge 203 supports the lower edge 1111.

[0061] In practical application, when a wire C is inserted through the wire jack 22, it can extend into the position between the clamping end 123 and the end wall 113, and the elastic clamping end 123 cooperates with the end wall 113 to clamp the wire C; if a tool is inserted into the operation hole 23, it can be pushed against the position between the clamping end 123 and the arc-shaped portion 121, so that the clamping end 123 is separated from the wire C, facilitating the wire C to be taken outwards.

[0062] Compared with the structure of the main body disclosed in the previous utility model case No. M611988, the mouth portion 112 and the end wall 113 of the conductive terminal 11 of the present utility model are formed by the way of breaking and bending. Therefore, in the process of forming, the material at the edge of the mouth portion 112 will not be stretched, effectively avoiding the defects such as insufficient structural strength and poor conductivity caused by the thinning of the connecting part between the end wall 113 and the mouth portion 112 due to stretching; at the same time, the auxiliary convex portion 202 of the side cover 20 and the convex portion 26 of the terminal block 2 can not only jointly support both sides of the conductive terminal 11 to form a relatively stable positioning effect, improve the stability of the assembly of the conductive terminal 11 with the terminal block 2 and the side cover 20, but also form movable guiding and lateral limiting on both sides of the clamping end 123 and the inserted wire C, effectively avoiding the offset and skew of the metal elastic piece 12 during the movement process, or the loosening situation caused by the force pulling during the subsequent arrangement of the wire C.

[0063] See Figures 5 to 7As shown, the second embodiment of this utility model is considered to include the following structure: at least one second terminal unit A2, at least one third terminal unit A3, and a first terminal unit A1 identical to that in the first embodiment; wherein the second and third terminal units A2 and A3 are spaced apart between the terminal base 2 and the side cover 20 of the first terminal unit A1, the second terminal unit A2 has a terminal base 2a and a terminal assembly 1 identical to that in the first embodiment, and the terminal base 2a has the same housing as the terminal base 2 in the first embodiment. The terminal assembly 1 has a structure including a space 21, a positioning post 213, a first channel 211, a second channel 212, a wire insertion hole 22, a connecting part 24, a protrusion 26, and an operating hole 23. The terminal assembly 1 is assembled in the receiving space 21 of the terminal base 2a in the same manner as the first embodiment described above. The difference is that the terminal base 2a has a connected part 25 corresponding to the connecting part 24 and a sub-protrusion 27 corresponding to the protrusion 26 on the side surface away from the receiving space 21, and an upper edge 271 is provided on the top edge of the sub-protrusion 27.

[0064] The third terminal unit A3 has a terminal assembly 1a and a terminal base 2a that is the same as the aforementioned second terminal unit A2. The terminal assembly 1a has a conductive terminal 11a and a metal spring 12 that is the same as the aforementioned first embodiment. The conductive terminal 11a has the same structure as the aforementioned conductive terminal 11, such as a base 111, an opening 112, a positioning part 114, and an end wall 113. The difference is that the base 111 bends and extends a lead 116 at one edge near the end wall 113.

[0065] When the terminal assembly 1a is assembled in the receiving space 21 of the terminal base 2a, the pin portion 116 can extend to the outside of the terminal base 2a through the second channel 212 (or the first channel 211); in addition, the corresponding combination relationship between the conductive terminal 11a, the metal spring 12 and the terminal base 2a is the same as the corresponding combination relationship between the conductive terminal 11, the metal spring 12 and the terminal base 2 in the first embodiment described above, and will not be described in detail here.

[0066] In practical applications, the second and third terminal units A2 and A3 can be spaced apart between the terminal base 2 and the side cover 20 of the first terminal unit A1, so that the first, second, and third terminal units A1, A2, and A3 can be combined to form a terminal device B; for example Figure 5As shown, the terminal base 2a of the second terminal unit A2 is combined with the coupled portion 25 of the side cover 20 by the connecting portion 24; at this time, the protrusion 26 of the terminal base 2a and the sub-protrusion 202 of the side cover 20 can respectively extend into the side portion 117 on both sides of the opening 112 of the conductive terminal 11 of the terminal assembly 1, and are supported by the upper edge 261 and 203 on the lower edge 1111 to form a positioning, so that the protrusion 26 and the sub-protrusion 202 can form a movable guide and lateral limit on both sides of the locking end 123.

[0067] The terminal block 2a of the second terminal unit A2 is combined with the connecting portion 24 of the terminal block 2a of the third terminal unit A3 by the connecting portion 25. At this time, the protrusion 26 of the terminal block 2a of the third terminal unit A3 and the sub-protrusion 27 of the terminal block 2a of the second terminal unit A2 can respectively extend into the side portion 117 on both sides of the opening 112 of the conductive terminal 11a of the terminal assembly 1a, and are positioned by the upper edge 261 and 271 supported on the lower edge 1111, so that the protrusion 26 and the sub-protrusion 27 can form movable guidance and lateral limitation on both sides of the locking end 123.

[0068] The terminal block 2a of the third terminal unit A3 is combined with the terminal block 24 of the first terminal unit A1 by the coupling part 25. At this time, the protrusion 26 of the terminal block 2 and the sub-protrusion 27 of the terminal block 2a can respectively extend into the two sides below the opening 112 of the conductive terminal 11 of the terminal assembly 1, and are supported by the upper edge 261 and 271 on the lower edge 1111 to form a positioning, so that the protrusion 26 and the sub-protrusion 27 can form a movable guide and lateral limit on both sides of the locking end 123.

[0069] In summary, the wire connection terminal assembly structure of this utility model can indeed achieve the effects of improving the strength of the end wall structure, enhancing conductivity, smoothly guiding the movement of the metal spring, and preventing misalignment and loosening under force. It is a novel and progressive utility model, and therefore, a utility model patent application is filed in accordance with the law. However, the above description is only a description of the preferred embodiment of this utility model. All variations, modifications, alterations, or equivalent substitutions that extend from the technical means and scope of this utility model should also fall within the scope of this utility model patent application.
