Abstract

The utility model relates to an electronic connection device with the three-point contact, comprising a daughter board, a mother board, a base, and multiple conducting pieces in a row. Stationary members on both sides of the base are provided with slots, and the conducting pieces in the row are consecutively inserted into the slots of the base connected with the conducting pieces. The conducting pieces in the row comprise double-side materials formed by single-side materials making use of the folding of side materials and have the effect of more holding force. Most conducting pieces which form the electrical contact with the daughter board are designed to form the three-point contact for implementing the purposes of stable holding and good contact quality.

Description

Electronic connection device with three-point contact

The utility model system has 3 contacts about a kind of, and daughter board is packed into or the electronic connecting apparatus of taking-up rapidly.

According to statistics on the market, be about the conducting strip in the electronic connecting apparatus of 80-90%, often find that chucking power deficiency and contact are not good, cause computer line fault, malfunctioning phenomenon, electronic connecting apparatus as another, it is to utilize both sides to extend the teat force application board to open, can take out daughter board, and limited because of the area that is subject to the space lock bolt, open at plate and lock bolt to be damaged or long-time operation makes operating personnel point pain, or because of the long-term clamping use generating material elastic fatigue in both sides, impact effect and wasting time and energy, make conducting strip can't bring into play elasticity, often produce unfavorable condition and abandoned, weak point is arranged in fact by the user.

The utility model is at the shortcoming of the above, severally thinks hard to the greatest extent, designs a kind of " electronic connecting apparatus with 3 contact shapes " eventually.

The main purpose of the utility model system provides a kind of electronic connecting apparatus with 3 contact shapes, can pack into fast or takes out daughter board assemblies, makes the device operation reduce the time.

Another purpose system of the utility model provides a kind of electronic connecting apparatus with 3 contact shapes, and the configuration of its conducting strip is 3 contacts, and it is very firm that daughter board is sandwiched in the middle of the biplate conducting strip, the difficult phenomenon of shaking.

The another purpose of the utility model is that a kind of electronic connecting apparatus with 3 contact shapes are provided, and the both sides fixed component of its pedestal is provided with a groove, and conducting strip in a row is inserted into joinably, to cooperate automated production.

The system of a purpose again of the utility model provides a kind of electronic connecting apparatus with 3 contact shapes, its conducting strip in a row is to utilize the waste part in the single piece of material to be flexed into the use of biplate material, because the biplate material has better elastic, make the effect of its chucking power that can double, because biplate that is double-deck flexible generation, can produce the buffering phenomenon of action, reduce the situation of permanent deformation.

For the above-mentioned purpose that makes the utility model and structure can be further for for the purpose of clear, conjunction with figs. is described in detail as follows now:

Fig. 1 is the isometric exploded view of the utility model;

Fig. 2 is the three-dimensional view of the utility model conducting strip in a row;

Fig. 3 is inserted in the groove of pedestal serially for the utility model conduction in a row; And

Fig. 4 is the profile of the utility model.

See also shown in Figure 1ly, the jockey 10 of the utility model is to include a pedestal 12, is disposed at conducting strip 20, in a row in the pedestal and is placed in following motherboard of pedestal 30 and the interior daughter board 40 of an embedding multi-conducting sheet 20; The two side ends of this pedestal 12 is provided with a groove 14, its function be with daughter board 40 fixed in position in groove 14, can pack or take out daughter board 40(easily into sees also shown in Figure 3), and can cooperate automated production, pedestal 12 connections are arranged in terminal board, can embed continuously in the accommodation hole 16 of pedestal 12 for conducting strip 20 in a row.

Seeing also shown in Figure 2ly, is the three-dimensional view of a conducting strip 20 in a row, and it includes contact portions 26 before column pin 22, one base portions 24; One back contact portion 28, reach one and connect strip 212, this conducting strip 20 in a row is to be overlapped into the biplate material by rim charge, it has the flexible chucking power of multiplication to strengthen and the contacting of daughter board 40, be provided with a snap point 214 at

strip

212 and 26 of preceding contact portions, so that strip 212 is separated with preceding contact portion 26 when making conducting strip 20 insert accommodation holes 16.

On multi-conducting sheet 20, be provided with a card-tight part 32, this card-tight part 32 can the punching out mode and the mode of conducting strip 20 one make, its function is many chucking positions when conducting strip 20 is positioned accommodation hole 16 on the pedestal 12, increases steadiness to form the chucking mode.

See also shown in Figure 4, when daughter board 40 is embedded contact 24, the teat that has a slyness because of forward and backward

contact portion

26,28, so that can pack into easily or choose when daughter board 40 is embedded, and there is sufficient space to make elastic displacement, to absorb embedment stress, can avoid permanent deformation to take place, and prolonged useful life.

Claims
