Description

Fool-proof structure capable of preventing reverse insertion during component loading

Technical Field

The utility model relates to a components and parts installation technical field, concretely relates to can prevent to insert anti-slow-witted structure of turning over when components and parts are gone up.

Background

On a Printed Circuit Board (PCB), various components are often used, such as various electronic components, capacitors, connectors, footprints, silk screen, and the like, for marking names and position frames of the components on the PCB, so as to facilitate maintenance and identification after assembly. Connectors, also known as connectors, plugs and sockets, generally refer to electrical connectors, i.e., devices that connect two active devices, transmitting current or signals.

The connectors are widely used, and among them, the most widely used connectors are single-row pin connectors and double-row pin connectors, which are used for erecting a communication bridge at a blocked position or between isolated and non-communicated circuits in a circuit, so that current flows and the circuit realizes a preset function. However, in the prior art, the following problems often occur when the connector is subjected to the loading operation: 1. in the prior art, most connectors of Tray packaging or Tape-on-wheel packaging or manually visual pin one symbol (pin identifier) are directly used for loading, but because the connectors adopting the Tray packaging generally need manual loading and the connectors adopting the Tape-on-wheel packaging have the risk of wrong direction, the problems of wrong connector positions and wrong connector pin positions are possibly caused when the connectors adopting the Tray packaging and the Tape-on-wheel packaging are used for loading and the manual loading of the pin one symbol is visually observed, and therefore the conventional connectors need technical personnel to verify after the loading is finished; 2. although install on the present partial connector and prevent slow-witted structure, the prevent slow-witted structure of present connector is generally additionally add a part on the connector body, perhaps sets up one in part and prevents slow-witted breach, but in the practical application process, the former can occupy the PCB space, and the latter is covered by the entity of other parts easily after last completion to technical staff carries out quick visual inspection in the aspect not, and reduces connector piece-loading efficiency.

Therefore, how to effectively prevent the component from being inserted reversely when the component is loaded and improve the component loading efficiency is a technical problem to be solved urgently by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a prevent slow-witted structure of anti-inserting when can preventing components and parts from loading to improve components and parts loading efficiency.

In order to solve the technical problem, the utility model provides a technical scheme is: the utility model provides a prevent slow-witted structure of anti-inserting when can prevent components and parts from loading, its includes the components and parts body, one side of components and parts body is provided with two at least pins, the pin includes ordinary pin and prevents slow-witted pin, the cross section of preventing slow-witted pin is different with the cross section of ordinary pin. Thus the utility model discloses only need to change one pin or a plurality of pins in the numerous pins of components and parts into the fool-proof pin that has different shapes or size, make in it can't insert the jack that other ordinary pins correspond, can effectually prevent that components and parts from being inserted anti-positively, moreover the utility model discloses need not the technical staff and confirm again after the completion of last components and parts whether insert anti-positively. Furthermore, because the utility model discloses only improve the pin of components and parts, it is not only that the cost change is little, still can not influence the plastic construction of components and parts body, and it can additionally not occupy the PCB space simultaneously yet.

Furthermore, the number of the fool-proof pins is one, the variation amount is minimum, the cost is lowest, and the anti-plugging effect is best.

Further, prevent slow-witted pin and be located the outside of all pins, this moment the utility model discloses can prevent effectively that components and parts from being inserted inversely.

Furthermore, the maximum width of the cross section of the fool-proof pin is greater than the maximum width of the cross section of the common pin, so that the fool-proof pin cannot be inserted into the jacks corresponding to other common pins.

Furthermore, the cross section of the fool-proof pin is different from the cross section of the common pin in shape, so that the fool-proof pin cannot be inserted into the jacks corresponding to other common pins.

Further, the length of the fool-proof pin is the same as that of the common pin, so that all the pins can be inserted into the position at the same time.

Furthermore, the fool-proof pin is made of the same material as the common pin, and the energization performance of the fool-proof pin is the same.

Further, the components and parts body is provided with prevents slow-witted sign to remind technical staff's the direction of placing of components and parts through preventing slow-witted sign secondary.

According to the technical solution provided by the utility model, the utility model has the advantages of it is following: firstly, the utility model can effectively prevent the component from being inserted reversely only by changing one or more pins of a plurality of pins of the component into foolproof pins with different shapes or sizes, so that the component can not be inserted into the jacks corresponding to other common pins, and in the loading process, the utility model can avoid the technical personnel from confirming whether the component is inserted reversely again after loading is completed, thereby greatly improving the loading efficiency; secondly, because the utility model discloses only improve the pin of components and parts, it is not only that the cost change is little, still can not influence the plastic construction of components and parts body, and it can additionally not occupy the PCB space simultaneously yet.
