Abstract
The invention discloses a switch with improved temperature sensing effect, which comprises a shell body, wherein a wiring terminal and a circuit element are arranged in the shell body; the wiring terminal is provided with a wiring hole; the circuit element is connected to the wiring hole through a lead wire; an overheat protection circuit is arranged in the circuit element; a temperature sensor is arranged in the overheat protection circuit; the part of the lead wire, connected to the wiring hole, is a columnar end; the side wall of the columnar end is provided with a lug with a jack; the temperature sensor is plugged in the insert hole; and an adhesive layer is wrapped at the joint position of the temperature sensor and the jack. In the invention, the temperature sensor and the lead wire are fixed with each other in a splicing manner and an adhesive bonding manner; and therefore, the connection strength is improved, and the temperature can be accurately sensed in time.
Description
Technical field
The present invention relates to a kind of appliance switch, relate in particular to the improvement of coupling part between switch inside conductor and the binding post.
Background technology
General electric switch all is by housing and is positioned at the some circuit elements of housing and constitutes, for the ease of inserting external power source or load, in housing, all have binding post (binding post), and the circuit element in the housing also inserts this binding post by lead, insert binding post for the ease of lead, the column that the position, termination of lead generally all is made of one or bar-shaped, to avoid the bifurcated of stranded conductor, also be convenient to insert the connecting groove (hole) of binding post, the lead that inserts binding post certainly in the individual switches has only one.
Integrated earth leakage protective or overvoltage protection in some switch; switch in actual application because a variety of causes; may cause element heating; especially when virtual connection takes place in the binding post position that connects load; the easiest generation in binding post position is overheated, even can damage accidents such as element, initiation fire; therefore add overheating protection circuit in a lot of switches, more effectively improved the switch fail safe.
The most key part is a temperature sensor in overheating protection circuit; for example generally adopt thermistor; thermistor can be arranged on the binding post position of easy heating; be bonded in the binding post position of inserting load by adhesive, can certainly set up thermistor at other binding post positions.
But by the main problem of bonding mode is that bonding strength can't guarantee; especially the long-term switch that under higher temperature conditions, uses; binding agent is very fast aging; reduce intensity; it is not tight to cause thermistor to combine with the binding post position; thermistor even might come off when running into switch and rock can't be sensed temperature in time, accurately, has had a strong impact on overheat protective function.
Summary of the invention
The invention provides a kind of switch that has overheat protective function, improved the fixed form of temperature sensor, improved bonding strength, can sense temperature in time, accurately, guaranteed the realization of overheat protective function.
A kind of switch that improves the temperature sensing effect; comprise housing; binding post and circuit element are housed in the housing; described binding post has wiring hole; described circuit element inserts this wiring hole by lead; be provided with overheating protection circuit in the described circuit element; be provided with temperature sensor in this overheating protection circuit; the part that described lead inserts wiring hole is the column termination; the sidewall of this column termination is provided with the lug of band jack; described temperature sensor is plugged in the described jack, interconnects the position at temperature sensor and jack and is enclosed with adhesive layer.
After lead inserted wiring hole, for secure wires, the sidewall at wiring hole in the described binding post had screw, built-in fastening bolt in the screw.The fastening bolt rotation can compress lead.
Described lug has two, the both sides that are distributed in the column termination of symmetry, the temperature sensor of not only can pegging graft, can also peg graft other elements or lead.
After wiring hole was inserted in described column termination, described lug was close to the outer wall of binding post, makes temperature sensor press close to binding post as far as possible, to react the temperature of lead and binding post contact site accurately.
Described lug and column termination are structure as a whole or weld, the jack of described lug and temperature sensor interference fit, the intensity after can guaranteeing to peg graft.General described temperature sensor is thermistor or other temperature-sensing elements.
Binder layer material can be selected existing general all kinds of binding materials with insulating properties for use, for example (but being not limited to) flame-resistant high-temperature-resistant silica gel etc.
Temperature sensor has improved bonding strength by pegging graft and the bonding two kinds of forms of binding agent and lead interfix among the present invention, and temperature sensor that can be promptly and accurately.
Description of drawings
Fig. 1 is the schematic diagram of the annexation between temperature sensor in the switch of the present invention and lead and the binding post.
Embodiment
Referring to accompanying drawing, a kind of switch that improves the temperature sensing effect of the present invention, comprise housing, binding post 3 and circuit element are housed in the housing, binding post 3 has wiring hole 1 and (has only schematically represented a wiring hole among the figure, in fact in order to insert circuit element and outside power supply or the load in the housing, the quantity of wiring hole can have a plurality of), circuit element inserts wiring hole 1 by lead, the part that lead inserts wiring hole 1 is column termination 4, the lug 6 that is provided with two band jacks 5 of the sidewall symmetry of column termination 4, lug 6 is structure as a whole with column termination 4 or welds.
Be provided with overheating protection circuit in the circuit element, be provided with temperature sensor in this overheating protection circuit, temperature sensor is a thermistor 7 in the present embodiment, and thermistor 7 is connected by lead 8 with other parts of overheating protection circuit.
During connection, in the jack 5 of the insertion lug 6 of thermistor 7 interference fit, then column termination 4 is inserted in the wiring hole 1, the sidewall of wiring hole 1 has screw, and built-in fastening bolt 2 in the screw compresses column termination 4 after fastening bolt 2 rotations.After wiring hole was inserted in column termination 4, lug 6 was close to the outer wall of binding post 3, makes thermistor 7 press close to binding post 3 as far as possible, to react the temperature of lead and binding post 3 contacts site accurately.
Finish peg graft and fastening after, interconnect the position at thermistor 7 and jack 5 and wrap up binding agent and solidify to form adhesive layer.
Thermistor has improved bonding strength by pegging graft and the bonding two kinds of forms of binding agent and column termination interfix among the present invention, and temperature sensor that can be promptly and accurately.
