[0059] Example 1

[0060] like Figure 1-12 As shown, the utility model provides a connection terminal, including a housing and a wire locking device 3. The housing includes a gland 2 and a base 1 that are buckled together, and the gland 2 and the base 1 are assembled to form a housing, and opposite first wire inlets 12 are respectively provided at both ends of the housing; the wire locking device 3 is installed in the space formed between the gland 2 and the base 1, and is used to connect at least two wires, and the wire locking device 3 includes a clamping member 31 and a connecting member 32, and the clamping member 31 includes a first clamping member 311 and a second clamping member 312, and the first clamping member 311 and the second clamping member 312 are connected through the connecting member 32; a clamping piece 33 is provided on the clamping member 31, and one end of the clamping piece 33 is linked to the clamping member 31, and the other end is a free end and forms a clamping opening for clamping the wire 4 with the connecting piece, and the clamping opening is distributed at both ends of the wire locking device 3, and corresponds to the first wire inlets 12 at both ends of the housing.

[0061] In the above scheme, the utility model provides a clamping piece 33 on the clamping member 31, and applies a clamping force to the wire 4 through the clamping opening formed by the clamping piece 33, which not only facilitates the insertion and connection of the wire 4, but also can stably fix the wire 4 to prevent the wire 4 from falling off, and can be used repeatedly. The utility model also sets the clamping member 31 as a left and right structure, so that the structure of the connecting terminal is further simplified, and two wires 4 can be connected at the same time, which is convenient to use. Specifically, the shell is made of insulating material. The shell is rectangular as a whole, and of course it can also be set to a square or other irregular shapes according to actual needs. The wire locking device 3 is made of conductive material, which can be but not limited to conductive metal materials. At least two wires 4 enter the connecting terminal from the wire inlets at both ends of the shell, and abut against the clamping opening, so that the two wires 4 are in a conductive state, and the two wires 4 can be connected through the connecting terminal.

[0062] In this example, the clamping member 31 is inclined toward the connecting member 32. The angle between the clamping member 31 and the connecting member 32 is 15° to 90°. Preferably, in order to further improve the clamping force of the clamping member 31 on the wire 4, the angle between the clamping member 31 and the connecting member 32 is 25° to 45°. The connecting member 32 is preferably arranged horizontally.

[0063] In this example, the clamping member 31 and the connecting member 32 are integrally formed and are in the shape of a trapezoid that opens upward. It is understandable that the integral forming method can improve the connection strength of the wire locking device 3, so that the overall structural strength of the connecting terminal is higher. The clamping member 31 includes a first clamping member 311 and a second clamping member 312, which are preferably integrally and symmetrically arranged. However, the shape of the wire locking device 3 of the present patent is not limited to this.

[0064] In this example, a clip 33 is provided on the clamping member 31, and the clip 33 is in a strip or rectangular shape, and is preferably formed by stamping from the clamping member 31 through a stamping process. One end of the clip 33 is connected to the clamping member 31, and the other end is a free end and forms a clamping opening with the connecting piece for clamping the wire 4. Specifically, a first clip 331 is provided on the first clamping member 311, and the upper end of the first clip 331 is connected to the first clamping member 311, and the lower end is a free end, and a first clamping opening is formed between the lower end of the first clip 331 and the connecting piece to clamp the exposed wire 4. Similarly, a second clip 332 is provided on the second clamping member 312, and the upper end of the second clip 332 is connected to the second clamping member 312, and the lower end is a free end, and a second clamping opening is formed between the lower end of the second clip 332 and the connecting piece to clamp the exposed wire 4.

[0065] like Figure 2-4As shown, in order to improve the clamping force of the clip 33 on the wire 4 and prevent the wire 4 from escaping, the upper end of the first clip 331 is provided with a first bending portion 3111 of the first clamping member that bends upward. The so-called upward bending is based on the orientation shown in the figure, including both directly above the clip 33 and obliquely above the clip 33. However, the orientation of the figure is not a limitation of the present patent technology, but is to illustrate the bending direction of the first bending portion 3111 of the first clamping member. The first bending portion 3111 of the first clamping member changes the plane shape of the first clip 331, so that the first clip 331 can generate a stronger elastic force. Correspondingly, a first clamping member second bending portion 3112 that bends downward is provided at the upper end of the first clamping member 311 and at a position corresponding to the first bending portion 3111 of the first clamping member. The bending directions of the first bending portion 3111 of the first clamping member and the second bending portion 3112 of the first clamping member are opposite. This structure can not only enable the first clamp 331 to produce a stronger clamping force, but also prevent the clamping member 31 from deformation. The bending angle of the first bending portion 3111 of the first clamping member is preferably in the range of 140° to 160°, and the bending angle of the second bending portion 3112 of the first clamping member is preferably in the range of 155° to 175 degrees.

[0066] Similarly, the upper end of the second clamping piece 332 is provided with a second clamping member third bending portion 3123 bent upward, and correspondingly, the upper end of the second clamping member 312 is provided with a second clamping member second bending portion 3122 bent downward at a position corresponding to the first bending portion of the second clamping member 312, and the bending directions of the second clamping member third bending portion 3121 and the second clamping member second bending portion 3122 are opposite. The bending angle of the second clamping member third bending portion 3123 is preferably in the range of 140° to 160°, and the bending angle of the second clamping member second bending portion 3122 is preferably in the range of 155° to 175 degrees.

[0067] The first clamping member 311 is provided with a first clamping member third bending portion 3113 at the upper end of the first clamping member second bending portion 3112, and the first clamping member third bending portion 3113 extends horizontally to form a first clamping member 311 limiting portion. The second clamping member 312 is provided with a second clamping member third bending portion 3123 at the upper end of the second clamping member second bending portion 3122, and the second clamping member third bending portion 3123 extends horizontally to form a second clamping member limiting portion 3124.

[0068] Furthermore, a notch 34 is provided at the free end of the clip 33, and a clamping opening is formed between the notch 34 at the free end of the clip 33 and the connector 32 to clamp the exposed wire 4. The notch 34 strengthens the fixation of the clip 33 to the wire 4.

[0069] In order to enhance the conductivity of the connection terminal and improve the contact effect, the clamping member further includes a bottom sheet 35, which is disposed above the connection sheet and fixedly connected to the connection member 32. Specifically, the bottom sheet 35 can be fixedly connected to the connection member 32 by riveting, welding or clamping. In this embodiment, the connection member 32 is provided with a plurality of rivet holes 321, and rivets 351 are disposed at positions corresponding to the rivets 351 on the bottom sheet 35, and the rivet holes 321 pass through the rivets 351 and fix the connection member 32 and the bottom sheet 35 together.

[0070] like Figure 5-8 As shown, the base 1 is a hollow rectangular parallelepiped structure with an open upper surface. The base 1 includes a base body 11 and a wire insertion hole 13. A cavity 14 for accommodating the wire locking device 3 is provided inside the base 1. The base body 11 includes a bottom plate 114 and a base end wall 111 disposed at both ends of the short side of the bottom plate 114. The base end wall 111 has a certain thickness. The wire inlet is disposed on the base end wall 111. The wire insertion hole 13 passes through the base end wall 111 and extends from the surface of the first wire inlet 12 toward the cavity 14.

[0071] In the above embodiment, the wire locking device 3 is installed in the cavity 14 of the base 1, and base side walls connected to the bottom plate end wall 111 and extending upward are provided on both sides of the bottom plate 114. The upper surface of the base body 11 is provided with a base opening 113 that penetrates the cavity 14, and the wire locking device 3 is installed in the cavity 14 of the base 1 through the base opening 113.

[0072] like Figure 5 As shown, the wire insertion hole 13 includes a first section 131 and a second section 132 for fixing the wire locking device 3, wherein the first section 131 is arranged on the base end wall 111 and penetrates the wall of the base end wall 111, and the second section 132 extends into the cavity 14. The second section 132 extends toward the cavity 14 and has an abutment block 1321 close to the first section 131 and a guide block 1322 connected to the abutment block 1321. The abutment block 1321 corresponds to the shape of the clamping member 31, and the abutment block 1321 and the base opening 113 form a limiting boss 141 for abutting the first clamping member limiting portion 3114 and the second clamping member limiting portion 3124, and the first clamping member limiting portion 3114 and the second clamping member limiting portion 3124 are limited in the limiting boss 141.

[0073] like Figure 7 As shown, a first clamping groove 142 for mounting the first clamping member 311 and the second clamping member is provided between the side wall of the base and the guide block 1322. When the wire locking device 3 is placed in the cavity 14 of the housing, the clip 33 of the wire locking device 3 is placed above the guide block 1322, and a portion of the first clamping member 311 and the second clamping member 312 will be confined in the first clamping groove 142.

[0074] In the above embodiment, the base cavity 14 further includes a second clamping groove 143 . The second clamping groove 143 is formed between the opposite second sections 132 . When the wire locking device 3 is inserted into the cavity 14 , the connecting member 32 is confined in the second clamping groove 143 .

[0075] like Figure 8 As shown, the guide block 1322 is inclined toward the connecting member 32, and the inclination angle is the same as that of the clamping member 31. The guide block 1322 includes a guide groove and a second wire inlet 1323, and the second wire inlet 1323 is located at the connection between the guide block 1322 and the abutment block 1321. The second wire inlet 1323 is smaller than the first wire inlet 12, so that the wire 4 can be more conveniently inserted into the connecting terminal. The shape of the guide groove matches the clip 33.

[0076] like Figure 9-11 As shown, the gland 2 includes a gland body 21 and a limiting convex rib. The gland body 21 as a whole can be, but is not limited to, a hollow rectangular parallelepiped structure with an opening at the lower end. A limiting convex rib is provided on the lower surface of the gland body 21 at a position corresponding to the wire locking device 3, and at least a part of the clamping member 31 of the wire locking device 3 is limited in the limiting convex rib. The setting of the limiting convex rib limits the structure of the connecting member 32 of the wire locking device 3, further enhancing the stability of the installation of the wire locking device 3, and ensuring that the wire locking device 3 will not be deflected due to a strong thrust when the wire 4 is inserted.

[0077] In this embodiment, the limiting ribs include a first limiting rib 221 and a second limiting rib 222. The first limiting rib 221 and the second limiting rib 222 are in a "[" shape as a whole, with the opening facing the wire inlet.

[0078] The first limiting rib 221 includes a first limiting end wall 2211 and a first limiting side wall 2212 extending downward and connected to both sides of the first limiting end wall 2211; the second limiting rib 222 includes a second limiting end wall 2221 and a second limiting side wall 2222 extending downward and connected to both sides of the second limiting end wall 2221. The first limiting end wall 2211 and the second limiting end wall 2221 can prevent the wire 4 from being inserted excessively, and are preferably in a square shape or the like for easy connection and limiting. Specifically, the first limiting rib 221 and the second limiting rib 222 are an integrally formed structure, which can improve the connection strength of the limiting ribs, so that the overall structural strength of the connection terminal is higher.

[0079] Further, the first limiting rib 221 further includes a first guide arm 2213 provided on the first limiting end wall 2211 and extending toward the first wire inlet 12; the second limiting rib 222 further includes a second guide arm 2223 provided on the second limiting end wall 2221 and extending toward the first wire inlet 12. Specifically, the first guide arm 2213 and the second guide arm 2223 are both in a trapezoidal shape, and the shapes match the first clamping member 311 and the second clamping member 312. Specifically, the trapezoidal shape can be, but is not limited to, a right-angled trapezoidal shape.

[0080] like Fig. 9 As shown, the first limiting side wall 2212 and the first limiting end wall 2211, the second limiting side wall 2222 and the second limiting end wall 2221 respectively form corresponding first limiting grooves 231, and the first limiting side wall 2212 and the second limiting side wall 2222 respectively form second limiting grooves 232 with the gland side wall 212. The second limiting grooves 232 are used to limit the transitional insertion of the wire 4 and to limit excessive deformation of the clip 33 when it is pushed open.

[0081] In the above embodiment, the gland 2 is provided with at least one gland test hole 24, and / or the base is provided with at least one base test hole, and a gland test hole 24 penetrating the gland is formed between the first limiting rib 221 and the second limiting rib 222, or the gland test hole 24 is provided on the limiting rib 22. Further, the gland test hole 24 is provided on the upper surface of the gland 2, between the first limiting rib 221 and the second limiting rib 222, so as to facilitate the detection of the conductive condition.

[0082] like Figure 6 and Fig.10 As shown, during installation, the base side wall and the base end wall 111 of the base body 11 are inserted into the opening of the lower surface of the gland 2. In order to facilitate installation and enhance the firmness of installation, the gland 2 and the base 1 can be connected by screw connection and / or snap connection of a snap assembly. Specifically, a snap assembly is provided between the gland side wall 212 and the base side wall. The snap assembly includes at least one snap opening 25 provided on the gland side wall 212 and a protruding block 15 provided on the base side wall and capable of cooperating with the snap opening 25.
