Abstract

The utility model relates to a short-circuit structure of a contact piece of a connector. The short-circuit structure comprises a connector, contact pieces, a plurality of conducting wires and a crimping sleeve, wherein two ends of each conducting wire are respectively welded or crimped with two contact pieces needed to be short-circuited on the connector, and middle parts of the conducting wires penetrate into the crimping sleeve and are welded or crimped in the crimping sleeve. According to the short-circuit structure, the short-circuit manner that each conducting wire corresponds to one contact piece in the prior art is changed into a manner that each conducting wire corresponds to two contact pieces, thus the quantity of the conducting wires used for short circuit is reduced by half, thereby solving the problem that the complicated circuit has many contact pieces needed to be short-circuited and is unable to be achieved, and simplifying the short-circuit structure and saving the internal space of the equipment.

Description

Short-circuit structure of contact piece of connector
Technical field
The utility model relates to a kind of electric connector, relates in particular to a kind of contact pin of connector or the short-circuit structure of contact piece of connector of the mutual short circuit of jack.
Background technology
Along with the volume of the development of science and technology, electronic equipment is more and more less, its inner space is also more and more less.In some systems or electronic equipment, the contact (contact pin or jack) of connector need to be realized the short circuit of contact and contact by line.The method that realizes the connector contact short circuit has: by core and contact welding or the crimping at wire two ends.When the contact of need short circuit is more, can and becomes a branch of rear welding or adopt crimp type terminal that the conducting wire end on each contact of need short circuit is carried out crimping the conducting wire end on each contact of need short circuit.
As shown in Figure 1, when needs with 5 contacts (plug or jack) short circuit the time, usually an end of 5 wires 2 and the contact of connector 1 need to be welded, the other end of these 5 wires just need to expose core 3, and all cores 3 are shorted together, weld or be crimped on together, namely weld or crimp type terminal 4, and it is accommodated in the heat-shrink tube 5.
In with upper type, when the contact that needs short circuit is more, adopt welding manner will violate welding process requirement, exceed the welding lead radical of regulation, cause easily the situations such as scolder soaks into deficiency, and welding quality is defective; When adopting crimp type terminal crimping mode, the overall dimension of connector will be subject to the impact of crimp type terminal overall dimension, when the overall dimension of connector hour, adopt crimp type terminal can't satisfy instructions for use.
Therefore, the utility model proposes a kind of short-circuit structure of contact piece of connector of practicality, can effectively solve the problem that the contact short circuit exists in processing in the existing part small size connector product.
The utility model content
Order of the present utility model provides a kind of short-circuit structure of contact piece of connector, for the limitation that exists on the contact short circuit processing mode in the part small size connector product, quantity and special-purpose crimp sleeve of the design of the wire gauge on the contact according to the short circuit contact, choose the wire of dimension by half of short circuit number of connections, peel insulating barrier off to expose core in the centre position of each wire, the wire that strips line is penetrated in the crimp sleeve, align with the core centre position that all strip out and rear crimp sleeve carried out crimping or welding in the centre position of crimp sleeve, subsequently the fishing line end wire stripping of each wire and with corresponding connector contact crimping or welding, at last the contact of handling well is assembled to the corresponding Kong Weizhong of connector.Can greatly reduce the product design size like this, lower product weight, guarantee the reliability of short circuit contact.
According to inventive concept of the present utility model, the technical solution of the utility model is: a kind of short-circuit structure of contact piece of connector, comprise connector and contact, it is characterized in that, also comprise some wires and a crimp sleeve, wherein, the two ends of described every wire need two contacts of short circuit to weld or crimping respectively with on the described connector, and the middle part of described wire all penetrates described crimp sleeve and welding or crimping in crimp sleeve.
Further, can be provided with the solder terminal identical with number of conductors or crimp type terminal in the described crimp sleeve, be convenient to the mode short circuit of wire by welding or crimping.
Technique effect of the present utility model is, the short circuit mode of the every corresponding contact of wire in the prior art is improved to corresponding two contacts of every wire, thereby will reduce half for the number of conductors of short circuit, not only solved the more and problem that can't realize of the contact that needs short circuit in the complicated circuit, also simplify on the other hand short-circuit structure, saved the device interior space.
Figure of description
Fig. 1 is the schematic diagram of short-circuit structure of contact piece of connector in the prior art;
Fig. 2 is the short-circuit structure schematic diagram of the utility model most preferred embodiment;
Fig. 3 is the design sketch of the actual use of the utility model.
Embodiment
Below describe the utility model in detail by a most preferred embodiment of the present utility model.In this manual, all " contacts " all refers to jack or the contact pin on the connector.No matter be jack or contact pin, all unification is called " contact " in this manual.
Shown in Fig. 2 and 3, short-circuit structure of contact piece of connector of the present utility model comprises connector 1, wire 2, crimp sleeve 6 and contact 7.The two ends of every wire 2 need two contact 7 crimping of short circuit respectively with on the connector 1, and the middle part of wire 2 penetrates crimp sleeve 6 and crimping in crimp sleeve 6.Adopt short circuit mode shown in Figure 2, only need 8 contacts to be shorted together with 4 wires.
The specific implementation of above-mentioned short-circuit structure can be: peel insulating barrier off to expose core in the centre position of each wire 2, and the wire 2 that will strip line penetrates in the crimp sleeve 6, be provided with the crimp type terminal (not shown) identical with number of conductors in the crimp sleeve 6, after aliging in the centre position that all crimp type terminals and all are stripped out the wire 2 of core, crimp sleeve 6 is carried out crimping, subsequently the fishing line end wire stripping of each wire 2 and with corresponding connector contact 7 crimping, handle well by contact 7, the component diagram that wire 2 and crimp sleeve 3 form as shown in Figure 2, to be assembled to by the contact 7 that Fig. 2 handles well at last connector 1 corresponding Kong Weizhong, namely become short-circuit structure as shown in Figure 3.
More than describe the utility model in detail by embodiment shown in Figure 2, those skilled in the art will be understood that, in other embodiment of the present utility model, the short circuit mode of wire middle part in crimp sleeve also can be that the solder terminal that respective numbers is set in crimp sleeve welds.Equally, the connected mode of wire two ends and contact also can be welding.
