Abstract
The invention belongs to low-voltage power transmission equipment, and relates to a plug-in wiring terminal of a drawer type circuit breaker. The circuit breaker comprises at least one pair of sockets and plugs which are arranged on a drawer seat and a circuit breaker body and are matched with each other; two pairs of contact pieces with arched cross sections are arranged on the socket, and an insulating partition plate is arranged between the two pairs of contact pieces; two pairs of metal pins matched with the contact pieces are arranged on the plug, and a slot matched with the insulating partition plate is formed between the two pairs of metal pins. After the structure is adopted, the reliable contact of the terminal in the insertion process can be ensured, so that the precision requirements on product manufacturing and installation are reduced, and the insertion reliability is improved. The whole section of the metal needle is embedded on the lower wiring terminal, so that the metal needle is effectively prevented from deforming. The connector can meet the requirement of the number of the terminals in a compact space, and meanwhile, the arrangement of the partition plate also ensures the reliable insulation among the contacts. In addition, the plugging structure is stressed evenly, and the contact reliability is high.
Description
?
Technical field
The invention belongs to low voltage power transmission equipment, relate to a kind of withdrawable circuit breaker plug-in connecting terminal.
Background technology
Circuit breaker is used for connecting the internal circuit and the externally fed circuit of certain limit, and its effect is equivalent to master switch, for the convenience of Maintenance and Repair, and withdrawable circuit breaker commonly used at present, it generally comprises two parts, the fixing drawout chassis and the breaker body of drawer type.Circuit on the drawout chassis links to each other with main circuit, and the circuit on the breaker body links to each other with external circuit.In order to connect main circuit and external circuit; General withdrawable circuit breaker all comprises upper connecting terminal and lower connecting terminal; Upper connecting terminal is installed on the body of drawout chassis, links to each other with internal circuit, and lower connecting terminal is installed on the breaker body; Link to each other with external circuit, through the connection of accomplishing entire circuit that is connected of upper connecting terminal and lower connecting terminal.
The binding post of existing withdrawable circuit breaker; Be made up of upper connecting terminal and lower connecting terminal, the connector in the connecting hole of the plug on the metal needle through the lower connecting terminal lower end and the corresponding upper connecting terminal continuous fetches the connection that realizes the circuit breaker secondary circuit.Because metal needle cooperates precision prescribed than higher with connector in the connecting hole, so occur the situation that dislocation, metal needle are out of shape during insertion easily, it is unreliable to contact.
Summary of the invention
The technical problem that the present invention will solve provides a kind of compact conformation, easily manufactured, withdrawable circuit breaker plug-in connecting terminal that the grafting reliability is high.
In order to solve the problems of the technologies described above, withdrawable circuit breaker plug-in connecting terminal of the present invention comprises at least one pair of socket and the plug that cooperatively interact that is separately positioned on drawout chassis and the breaker body; Said socket is provided with the contact that two pair cross-section shapes are arch, is provided with insulating barrier between two pairs of contacts; Said plug is provided with two pairs of metal needles that match with contact, has the slot that matches with insulating barrier between two pairs of metal needles.
Be set to the inclined-plane in the said slot.
Whole section of said metal needle is embedded on the end face and bottom surface of plug body.
After adopting above-mentioned structure; By the contact matching mode that has substituted arch contact and cooperating of metal needle contact pin and jack in traditional terminal structure; Contact range is big; Can guarantee terminal reliable contact during insertion, thereby reduce required precision, improve the reliability of pegging graft product manufacturing and installation.Metal needle is embedded in for whole section and has effectively prevented the metal needle distortion on the lower connecting terminal.Binding post contains four contacts; Being provided with dividing plate between two pairs of contacts separates; Make one group of socket and plug have four contacts, make its requirement that can in the space of compactness, satisfy the terminals number, the setting of dividing plate has simultaneously also guaranteed the reliable insulation between each contact.In addition,, make the connected structure stress equalization, can not influence the reliability of contact because of the one-sided stressed distortion that makes contact component because the contact of socket contacts with the metal needle of plug from upper and lower both direction.

Fig. 3 is a upper connecting terminal left view of the present invention;
Fig. 4 is a lower connecting terminal front view of the present invention;
Fig. 5 is a lower connecting terminal left view of the present invention.
Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, withdrawable circuit breaker plug-in connecting terminal of the present invention comprises at least one pair of socket 3 and plug 4 that cooperatively interact that is separately positioned on drawout chassis and the breaker body; Said socket is provided with between 5, two pairs of contacts of contact that two pair cross-section shapes are arch and is provided with insulating barrier 6;
Like Fig. 4, shown in 5, plug 4 is provided with between 7, the two pairs of metal needles of two pairs of metal needles that match with contact 5 and has the slot 8 that matches with insulating barrier 6.
Through above-mentioned structure, when plug 4 was connected with socket 3, the surface that the contact 5 of arch shape arches upward on the metal needle of plug 4 and the socket was in contact with one another, because domes have elasticity preferably, thereby had guaranteed that contact portion has enough contact pressures.
As shown in Figure 5, be provided with the inclined-plane that can play the guiding role in the above-mentioned slot 8.
Like Fig. 4, shown in Figure 5,7 whole sections of above-mentioned metal needles are embedded on the end face and bottom surface of plug 4 matrixes, thereby effectively prevent the metal needle distortion.
