Detailed description of the invention
In order to make object, technical scheme and the advantage of the clamping connection frock for cold junction of the present utility model clearer, below in conjunction with concrete drawings and the specific embodiments, the utility model is further elaborated.
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.
Cold junction is a kind of attaching parts of commonly using.It is mainly used in connecting all parts of air-conditioner in air-conditioner.At present to the requirement of cold junction be requirement its durable and with miscellaneous part no-float, especially require the lead-in wire of cold junction inside to be fixed well, lead-in wire can not drop out.
In order to ensure that the each parts in cold junction especially go between and are fixed well, avoid the problem that occurs that lead-in wire drops out, referring to Fig. 1, the utility model provides a kind of clamping connection frock for cold junction, comprise interconnective the first clamping connection assembly 100 and the second clamping connection assembly 200, the first clamping connection face 110 of described the first clamping connection assembly 100 and the second clamping connection face 210 of the second clamping connection assembly 200 are oppositely arranged the jaw that forms described clamping connection frock; On described the first clamping connection face 110, be provided with at least two protuberances 111, between adjacent protuberance 111, form standing groove 112; On described the second clamping connection face 210, be provided with at least two grooves 211, between adjacent two grooves 211, form clamping connection portion 212; Described protuberance 111 is corresponding with the position of described groove 211, and described standing groove 112 is corresponding with the position of described clamping connection portion 212; The cross-sectional area of described groove 211 is greater than the cross-sectional area of corresponding described protuberance 111, and the cross-sectional area of described standing groove 112 is greater than the cross-sectional area of corresponding described clamping connection portion 212.
Referring to Fig. 1, the first clamping connection assembly 100 and the second clamping connection assembly 200 in the present embodiment interconnect, when use, cold junction is placed in jaw, then the first clamping connection assembly 100 and the mutual compression of the second clamping connection assembly 200 can be completed to the assembling of cold junction, very convenient when therefore the clamping connection frock of the present embodiment is used.In order to reach better clamping connection effect, the first clamping connection face 110 of the first clamping connection assembly 100 is set to concaveconvex structure by the present embodiment, as shown in Figure 1, be provided with protuberance 111 and standing groove 112 on the first clamping connection face 110, wherein standing groove 112 is used for placing cold junction.Accordingly, will groove 211 and clamping connection portion 212 be set in the second clamping connection face 210, when clamping connection, clamping connection portion 212 contacts with cold junction.It should be noted in the discussion above that referring to Fig. 3, in the time that this clamping connection frock is closed, the first clamping connection face 110 and the second clamping connection face 210 are not to engage completely, protuberance 111 and groove 211 be not engage completely and standing groove 112 and clamping connection portion 212 engage completely.Protuberance 111 in the present embodiment height corresponding with the position of groove 211 and protuberance 111 is less than or equal to the degree of depth of groove 211, but the cross-sectional area of protuberance 111 is less than the cross-sectional area of groove 211, standing groove 112 and the position height corresponding and clamping connection portion 212 of clamping connection portion 212 are less than or equal to the degree of depth of standing groove 112, but the cross-sectional area of standing groove 112 is greater than the cross-sectional area of clamping connection portion 212, the area of clamping connection portion 212 reduces, pressure increases, the clamping connection action effect that can effectively strengthen this clamping connection frock under the condition of same large clamping connection power is set like this.
Preferably, as a preferred embodiment, the width of standing groove 112 is less than the width of cold junction.Can better push like this and make together with " alloy aluminum " of joint inside be screwed in lead-in wire, to make the combination of cold junction firm.
Preferably, as a preferred embodiment, the surface smoothing transition of clamping connection portion 212.It is the smooth of the edge of clamping connection portion 212; without sharp edge and incomplete phenomenon; and the corner of clamping connection portion 212 is fillet; because clamping connection portion 212 directly contacts with the epidermis of cold junction; therefore the surface smoothing transition of the clamping connection portion cold junction of can effectively fitting; alleviate the dynamics of extruding, effectively protected the epidermis of cold junction.
Preferably, as a preferred embodiment, the cross section of protuberance 111 is rectangle or trapezoidal.The surface that is protuberance 111 has obvious rib, and setting can further increase the clamping connection effect of clamping connection frock like this.
Preferably, as a preferred embodiment, referring to Fig. 3, in the time that jaw is closed, the opening number of degrees of jaw are greater than 0 degree and are less than 10 degree.In the time of the first clamping connection assembly 100 and the second clamping connection assembly 200 closure, between the first clamping connection face 110 and the second clamping connection face 210, be not to fit completely, only have one end and second clamping connection face 120 1 end in contact of the first clamping connection face 110, and the other end of the first clamping connection face 110 does not contact with the other end of the second clamping connection face 120, between the first clamping connection face 110 and the second clamping connection face 210, there is certain angle.Both there is gap when closed in the first clamping connection assembly 100 in the present embodiment and the second clamping connection assembly 200, and this gap again can be not excessive.So both ensured clamping connection dynamics, and can avoid again cold junction not damaged in the time of the closed limit, thus avoid safety test and after sale in there are quality problems.The present embodiment split shed number of degrees are that the tension force angle by jaw is set realizes.
Preferably, as a preferred embodiment, referring to Fig. 2, clamping connection frock also comprises the baffle plate 300 that is arranged on jaw position, and baffle plate 300 is fixed on the first clamping connection assembly 100.The object that baffle plate 300 is set is in order to carry out spacing to cold junction, as long as make the end of cold junction prop up baffle plate just can to ensure the clamping connection position consistency of cold junction when placement, and just can ensure the best clamping connection position of cold junction by the width of the first clamping connection assembly is set, increase the reliability of clamping connection.
Better, the maximum opening degree when width of baffle plate 300 is greater than described jaw and opens.Arrange like this and facilitate cold junction to place.
Better, baffle plate 300 and the vertical setting of the first clamping connection face 110.Setting more can ensure the placement location of cold junction like this, has ensured the reliability of assembling.
The clamping connection frock for cold junction in the utility model has taken into full account the factor of cold junction assembling, is provided with concavo-convex clamping connection in the face of cold junction carries out clamping connection, has ensured clamping connection effect, cold junction is protected again simultaneously.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claim.
