Abstract
A low-resistance test switch card for printed circuit boards comprises a switching circuit card with network points arranged on one side thereof, and is characterized in that the network points on one side of the switching circuit card are connected to a probe strip matched with a needle stand slot on a dedicated test fixture. Compared with the prior art, the utility model has the benefits that when the switch card is in direct matched insertion and connection with the needle stand slot on the back plate of the dedicated test fixture, the problem that greater contact resistance errors are caused by frequent friction between an arrange-line and an oxhorn socket as well as between the arrange-line and an arrange-line socket can be overcome, so that the testing accuracy is greatly improved; not only are the fragile arrange-line and the fragile oxhorn socket eliminated, but also the production cost of the dedicated test fixture is greatly reduced, and time spending in inserting and plugging the arrange-line is saved, so that the test efficiency is greatly improved; and the utility model also can greatly reduce technical requirements to the test operating staff, so that a general worker can fulfill the operations of loading, unloading and debugging during the test of a printed circuit board. Therefore, the utility model is highly suitable for mass production and use in PCB factories.
Description
Technical field
The utility model relates to printed circuit board test fixture, especially a kind of printed-wiring board (PWB) low resistance Test Switchboard card.
Technical background
As everyone knows, all electric equipments or control system are all wanted the application of printed wiring board, are not short-circuited or open circuit for guaranteeing wiring board, and printed-wiring board (PWB) all need be tested before dispatching from the factory.At present, a kind of special test anchor clamps of being made up of anchor clamps and on-off circuit card connection are adopted in the test of printed-wiring board (PWB) usually, the anchor clamps of this special test anchor clamps are provided with the ox horn socket, and the on-off circuit card is provided with the winding displacement socket, is connected as a single entity by wire plug connection between the two.Though the special test anchor clamps of this structure can satisfy the test of general printed-wiring board (PWB).But along with the development of wiring board industry, the printed-wiring board (PWB) internal resistance sharply raises less than 1 ohm low resistance testing requirement.And existing special test anchor clamps are because anchor clamps are to be connected by wire plug connection with the on-off circuit card, and its resistance value can only satisfy usually that to test internal resistance be 20 ohm printed-wiring board (PWB).And existing special test anchor clamps not only need plug winding displacement and expend the plenty of time, and simultaneously because winding displacement and ox horn socket all are consumable accessorys, therefore it not only can influence the printed-wiring board (PWB) test duration, can influence proper testing when serious.
The utility model content
Technical problem to be solved in the utility model is to remedy above-mentioned the deficiencies in the prior art, and proposing does not a kind ofly have winding displacement bindiny mechanism and be applicable to the printed-wiring board (PWB) low resistance Test Switchboard card of internal resistance less than 1 ohm of test.
The utility model is solved by the following technical programs.
This printed-wiring board (PWB) low resistance Test Switchboard card comprises: avris is arranged the on-off circuit card that is provided with nexus.
The characteristics of this printed-wiring board (PWB) low resistance Test Switchboard card are:
The nexus that described on-off circuit edge side is arranged be connected with one can be adaptive with needle stand slot on the special test anchor clamps the probe bar.
Technical matters of the present utility model is solved by following further technical scheme.
Described probe bar is made of the double pin of arranging, the probe and the PCB bar of arrangement, be provided with in the described PCB bar with on-off circuit edge side and arrange the corresponding connection line of each nexus, each connection line contact that PCB bar dorsal part is arranged and each double pin one end soldering of arrangement connect, and each connection line contact that PCB bar face side is arranged and each probe foot soldering of arrangement connect.
Each double pin that described probe bar dorsal part is arranged end in addition is connected with each nexus soldering that on-off circuit edge side is arranged, and links with on-off circuit to be one.
The utility model beneficial effect compared with prior art is:
1. rely on the inserting be arranged on needle stand slot on on-off circuit card probe bar and the special test anchor clamps backboard to be connected the grafting of ox horn socket and winding displacement, winding displacement and winding displacement socket in the alternative prior art, it has not only reduced the grafting link of on-off circuit card and special test anchor clamps connection line, and can thoroughly eliminate because the big contact resistance error that produces because of frequent inserting friction between winding displacement and ox horn socket and winding displacement socket greatly improves measuring accuracy;
2. adopt the direct inserting of needle stand slot on the utility model switch card and the special test anchor clamps backboard to be connected, the winding displacement and the ox horn socket that have not only had rapid wear, can reduce the cost of manufacture of special test anchor clamps greatly, and no longer need to improve testing efficiency greatly because of the plug spent plenty of time of winding displacement.It also can reduce test operation personnel's technical ability requirement greatly, makes the common laborer also can finish the loading and unloading debugging operations to the printed wire board test.Be fit to very much PCB factory use of large-scale production.
The concrete structure of the utility model printed-wiring board (PWB) low resistance Test Switchboard card is provided in detail by the following drawings and embodiment.

Fig. 2 is a printed-wiring board (PWB) low resistance Test Switchboard card front view shown in Figure 1;
Fig. 3 is the structure for amplifying synoptic diagram at printed-wiring board (PWB) low resistance Test Switchboard card A shown in Figure 2 position.
Embodiment
Embodiment: can be clear that from Fig. 1 and Fig. 2 printed-wiring board (PWB) low resistance Test Switchboard card is arranged the on-off circuit card 1 that is provided with nexus 11 by avris and the bar 2 of popping one's head in is formed.
Described probe bar 2 as shown in Figure 3, probe 22 and PCB bar 23 by the double pin of arranging 21, arrangement constitute, be provided with in the PCB bar 23 and on-off circuit card 1 avris nexus 11 corresponding connection line (not shown), PCB bar 23 dorsal parts each connection line contact 231 of arranging and each double pin 21 1 end soldering of arranging connect, and 23 sides of PCB bar each connection line contact 232 of arranging and each probe 22 foot soldering of arranging connect.
Each double pin 21 that described probe bar 2 dorsal parts are arranged end in addition is connected with nexus 11 solderings that on-off circuit card 1 avris is arranged, and is connected as a single entity with on-off circuit card 1.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, its framework form can be flexible and changeable, can the subseries product.Just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
