Abstract

An improved connecting piece terminal relates to the field of the electric connecting piece, which comprises a main body and arm parts, wherein the main body and the two arm parts form an U shape into a whole, a welding part is arranged under the main body, and is provided with a through hole, the end of each arm part is provided with a holding part through extending upwards, the holding parts are close with each other, the end of each holding part is provided with a guide plate which horizontally extends and has the ends symmetrically bent outwards, and a first protruding part and a second protruding part with different length are oppositely extended on the two sides of at least one arm part. In the utility model, since the space between two adjacent terminals arranged on a tape can correspond to the space between the holding holes of the terminal of a socket connector, so a row of terminals on the tape can be inserted in the corresponding holding holes of a row of terminals at a time, thereby, the assembling efficiency of the terminal is improved.

Description

The connector terminal of improvement

Technical field

The utility model relates to a kind of connector terminal, especially refers to a kind of terminal that circuit board is connected with microprocessor that is used for.

Background technology

Because the high speed development of electronic technology, various computer fittings be emerge in multitude thereupon also, therefore, the demand of each computer fittings manufacturer in order to cater to productions, to live made great efforts the improvement technology always, enhances productivity.With the connector terminal is example, is connected the terminal of usefulness with microprocessor for circuit board, and it should have small and exquisite, the frivolous convenience of structure, it is reliable to connect, be easy to characteristics such as plug-in mounting.

In the known systems, a kind of bonder terminal that United States Patent (USP) (patent No. is 6267615) was announced in calendar year 2001, as shown in Figure 1, this terminal is provided with base portion and coupled arm, base portion comprises body and from extended head in the relative both sides of body and weld part, body is at the end near weld part, and its both sides relatively stretch out and are provided with two following flanks, close head both sides stretch out relatively and are provided with two last flanks, but flank reaches following this terminal of flank fixing in connector on this.

Because terminal two arms are the metal material belt punch forming by the base band both sides, so the spacing of two abutting end is bigger on the strip, be generally 2～3 times of terminals of adjacent accepting hole spacing of microprocessor socket connector, a row terminal that so is on the strip must insert in the terminal accommodation holes that repeatedly could stick with corresponding one-tenth row setting fully, causes production efficiency to reduce.And, because the base portion of terminal directly links to each other with strip, if then strip is influenced by improper external force and bends when being out of shape and also can directly cause terminal to be out of shape.

The utility model content

The purpose of this utility model is to provide a kind of at the defective that exists in the above-mentioned prior art can improve terminal plug-in mounting efficient, can prevent to cause because of strip bending distortion the electric connector terminal of terminal distortion again.

In order to achieve the above object, the utility model adopts following technical scheme:

The connector terminal of improvement, comprise our department and arm, our department and two arms constitute U-shaped integral body, the below of described our department is provided with weld part, each arm end extends upward the clamping part of drawing close mutually, and be provided with the guide plate of horizontal projection at each clamping part end, be formed with spatial transition between two described guide plates, and its afterbody be outwardly-bent symmetrically.

On the both sides of at least one described arm, relatively be extended with first protuberance and second protuberance that are uneven in length, described first protuberance is longer than second protuberance, and, on described first protuberance and second protuberance, be respectively equipped with two projections, be formed with groove between two described projections.Described weld part is provided with the through hole that is used to weld the tin ball, and the utility model is connected to the tin ball bonding on the circuit board by described through hole.

The utility model is compared with prior art, its beneficial effect is: the spacing of being located at two abutting end on the strip can be corresponding with the terminal accommodating pitch of holes of socket connector, and the one-tenth that a row terminal that is on the strip can disposablely be stuck with in correspondence is listed as in the row terminal accommodation holes that is provided with, thereby has improved the terminal efficiency of assembling.In addition, when strip bending distortion, also can not cause the overall structure distortion of terminal.

Embodiment

Describe design feature of the present utility model in detail below in conjunction with Figure of description and specific embodiment.

The connector terminal of improvement is mainly used in being connected of microprocessor and circuit board, comprises our department 10 and arm 20.Our department 10 and two arms 20 constitute U-shaped integral body, and the below of described our department 10 is provided with weld part 11, and weld part 11 is provided with the through hole 110 that is used to weld the tin ball, and the utility model is welded on the circuit board by described weld part 11; Each arm 20 end extends upward the clamping part 30 that is parallel to each other and draws close gradually; Be provided with the guide plate 40 of horizontal projection at each clamping part 30 end, two 40 of described guide plates are formed with spatial transition 50, and its afterbody is relatively outwardly-bent, microprocessor pin (not shown) can enter described spatial transition 50 along described guide plate 40 easily, is pushed into then to fix between the two described clamping parts 30 and be electrically connected with its formation.

Relatively be extended with first protuberance 21 and second protuberance 22 that are uneven in length on the both sides of at least one described arm 20, described first protuberance, 21 to the second protuberances 22 are long.On described first protuberance 21 and second protuberance 22, be respectively equipped with projection 210 and projection 220, be formed with groove between described projection 210 and the projection 220.

When implementing the utility model, the spacing of being located at two abutting end on the strip 9 can be corresponding with terminal accommodation holes (not shown) spacing of connector on the socket, a row terminal 2 that is on the strip 9 can disposablely be stuck with in the terminal accommodation holes of described one-tenth row setting, thereby improved the efficiency of assembling of terminal 2.In addition, the utility model only its first protuberance 21 links to each other with described strip 9, therefore, even strip 9 bending distortion also can not cause the overall structure distortion of terminal 2, like this, has also guaranteed the accuracy of manufacture of the present utility model greatly, the production efficiency of raising.

The above only is a preferred embodiment of the present utility model; it is not any qualification that it is done; staff for this area; be understood that easily; under invention essence of the present utility model; every to its any minor variations or modification of doing, all just be considered as within its protection range.
