Detailed Description

The core of the invention is to provide a clamping fixed terminal which adopts a clamping fixed mode and can be quickly installed and detached.

In order to make those skilled in the art better understand the technical solution of the present invention, the following will describe the snap-fit type terminal of the present invention in detail with reference to the accompanying drawings and the specific embodiments.

As shown in fig. 1 and 2, which are a front view and a plan view of a snap-fit type terminal provided by the present invention, respectively; the invention provides a clamping fixed terminal, which comprises a splicing end 1 and a clamping piece 2 which are relatively and fixedly connected, wherein the splicing end 1 and the clamping piece 2 jointly form a whole terminal structure; the splicing end 1 is connected with the mainboard through a signal wire and can transmit signals with the mainboard; the plug end 1 is a socket structure, and can be a USB or other socket.

The joint piece 2 sets up in the both sides that grafting end 1 is relative, and joint piece 2 has the trend that opens to both sides, and joint piece 2 is the foil, its one end and grafting end 1 relatively fixed, the other end and the separation of grafting end 2 to because of its self elasticity can outwards expand, when exerting pressure to joint piece 2, can make joint piece 2 produce elastic deformation, joint piece 2 receives the surface that can laminate grafting end 1 when pressing.

The two side edges of the engaging piece 2 are provided with engaging grooves 21, as shown in fig. 2, the engaging grooves 21 are substantially U-shaped and are defined by two side edges and a bottom edge, and the opening faces the outside of the engaging piece 2. The clamping groove 21 is used for being clamped in a limiting notch arranged on a clamping connection plate of the case, and is a front view of the clamping sheet 2 matched with the clamping connection plate of the case as shown in fig. 3; FIG. 4 is a side view of the card of FIG. 3 showing the engagement of two of the card tabs 2 with the housing card interface plate, wherein A is the housing card interface plate; spacing breach on the joint board of quick-witted case is the U-shaped groove structure, joint piece 2's face is roughly perpendicular with quick-witted case joint board's face, because joint piece 2 has the open trend of outside elasticity, consequently the draw-in groove 21 of joint piece 2 can block in quick-witted case joint board's the breach when not having other external force, also be the direction that the arrow in figure 4 shows, when joint piece 2 and quick-witted case joint board's breach mutual joint, joint board's surface blocks joint piece 2 formation, as shown in figure 3, joint piece 2 can't remove along left right direction.

The clamping sheets 2 arranged on the two sides of the inserting end 1 are respectively clamped with the case, so that the inserting end 1 is clamped on the case, and the inserting end 1 achieves a stable position limiting effect through the clamping sheets 2 on the two side faces. The clamping fixed type terminal is arranged on the case in a clamping mode, welding or bolt fixing connection is not needed, the clamping fixed type terminal can be quickly installed, and assembly efficiency is improved.

When the installation is carried out, the clamping sheets 2 at two sides are pressed relatively, namely the direction of an arrow in fig. 4 is opposite, so that the two clamping sheets 2 are close to the inserting end 1, the clamping groove 21 and the clamping plate of the chassis are aligned to release external force, the two clamping sheets 2 rebound along the direction of the arrow and are clamped in corresponding gaps respectively, and the installation step can be completed; when needing to be dismantled, press two joint pieces 2 relatively, shift out joint piece 2 from the breach of quick-witted case joint board, again with whole fixed terminal of joint release can.

On the basis of the scheme, the rear end of the clamping piece 2 is relatively fixed with the inserting end 1, the front end of the clamping piece 2 can be separated from the inserting end 1, as shown in fig. 2, the left side part is the front end, the right side part is the rear end, the right side is located on the inner side of the case, and the left side is exposed through the opening on the case. In addition, the front end of the snap-in piece 2 and the plug-in terminal 1 can be fixed relatively, and the rear end is separated and opened, and these embodiments are all included in the protection scope of the present invention.

As shown in fig. 3, the locking slot 21 is a symmetrical groove formed by recessing the edge of the locking piece 2 toward the middle. In addition, as shown in fig. 5, it is a schematic structural view of a second embodiment of the clip sheet 2; two lug structures can be arranged on the edges of the two sides of the clamping piece 2 respectively, and the clamping groove 21 is formed by the two lug structures, so that the same technical effect can be realized.

The plug-in end 1 is a flat block-shaped structure and is provided with four side faces, the four side faces are opposite in pairs, the clamping piece 2 is arranged at the narrower side face of the plug-in end 1, namely the side face where the wide side of the cross section is located, and the width of the clamping piece 2 in the structure is smaller; of course, if necessary, the side where the wider side of the plug-in terminal 1 is, that is, the side where the long side of the cross section is located; or all four sides are provided with clamping tabs 2.

On the basis of any one of the technical schemes and the mutual combination thereof, the invention arranges the fool-proof block 3 on the plug-in end 1, the fool-proof block 3 is used for being matched and clamped with the fool-proof clamping groove on the case to limit the plug-in direction, the fool-proof block 3 makes at least one side surface of the plug-in end 1 different from the opposite side surface, and the fool-proof block 3 is just clamped with the fool-proof clamping groove on the case, thereby ensuring that the fool-proof block cannot be installed reversely when being installed; the number and form of the fool-proof blocks 3 are not limited and can be set according to the needs.

The clamping sheet 2 is bent to form an arc-shaped boss 22 close to the inner end, the boss 22 enables the outer end of the clamping sheet 2 to have a tendency of opening towards two sides, the boss 22 is bent by the clamping sheet 2 to form an arc structure, and the tail end of the clamping sheet 2 is enabled to open towards two sides better through the boss 22 so as to guarantee the clamping effect.

Specifically, the two opposite clamping sheets 2 are integrally bent and formed, and the two clamping sheets 2 have the same structure and are convenient to process.
