The process of the snap gauge group of Fig. 6 being inserted to the card connector 100 shown in Fig. 1 and being taken out from card connector 100 referring to accompanying drawing 7-8 explanation.
As shown in Figure 7a, show snap gauge group 6 and do not insert the state of card connector 100 completely.Fig. 7 b shows the enlarged drawing of the part A of Fig. 7 a.Fig. 7 c shows the view of the housing 2 of removing card connector from Fig. 7 a.Fig. 7 d shows the state that snap gauge group 6 is inserted card connector 100 completely.Fig. 7 e shows the enlarged drawing of the part B of Fig. 7 d.Fig. 8 a shows the situation by promoting sliding bar 3, snap gauge group 6 being ejected from card connector 100 under normal circumstances.Fig. 8 b shows the enlarged drawing of the part C of Fig. 8 a.Fig. 8 c shows the situation of directly snap gauge group 6 being extracted from card connector 100 due to user misoperation.Fig. 8 d shows the enlarged drawing of the part D of Fig. 8 c.
As shown in Fig. 7 a-7b, when housing 2 and sliding bar 3 are assembled on pedestal 1, described the first elastic arm 20 and described first elastic arm 20 adjacent with sliding bar 3 is positioned at the inner side of card connector with respect to sliding bar 3.As shown in Figure 7 c, when snap gauge group 6 is inserted in spatial accommodation 10, along with snap gauge group 6 pushing along arrow Z1 direction, the top butt of snap gauge group 6 one end that extends into spatial accommodation 10 that promotes link member 14, link member 14 is rotated around pivot member 13 as shown in arrow Z3, thereby the other end of link member 14 promotes the elbow 31 of sliding bar 3, and sliding bar 3 sliding tray 12 along pedestal 1 as shown in arrow Z2 is outwards moved.
For another example shown in Fig. 7 a and 7b, due to when initially inserting, the protuberance 30 of sliding bar 3 staggers with the end 201c of the hook portion 201 of elastic arm 20, protuberance 30 substantially corresponding hook portion 20 to the outstanding part of spatial accommodation 10, therefore, between elastic arm 20 and sliding bar 3, have larger gap X, elastic arm 20 has larger outside mobile space.In the process inwardly pushing in snap gauge group 6, understand the outer thruster to spatial accommodation 10 elastic arm 20, towards sliding bar 3, promote the hook portion 20 of elastic arms 20; Meanwhile, snap gauge group 6 promotes link member 14, and link member 14 rotarily drives sliding bar 3 motions, and the distance Y between protuberance 30 and the end 201c of hook portion 201 is reduced gradually.
In addition, as shown in Fig. 7 d and 7e, when snap gauge group 6 is inserted in card connector 100 completely, the hook portion 201 of housing 2 both sides engages respectively the engagement grooves 63 and 64 in snap gauge group 6, thereby snap gauge group 6 is locked in card connector 100.Now, the protuberance 30 of sliding bar 3 moves near the end 201c of hook portion 201 of elastic arm 20, and relative with the end 201c of hook portion 201, between the protuberance 30 of sliding bar 3 and the end 201c of elastic arm 20, there is less gap X, the limited space that elastic arm 20 or hook portion 201 are outwards moved.
Insertion and locking for the ease of snap gauge group, preferably, the first kink 201a of described elastic arm 20 or 21 hook portion 201 generally perpendicularly bends from described elastic arm, and described the second kink 201b shows greatly from described the first kink 201a the angle folding that is less than or equal to 45 degree.
And, preferably, the development length of the second kink 201b of the hook portion 201 of described the first elastic arm 20 is greater than the development length of the second kink 211b of the hook portion 211 of described the second elastic arm 21, and the end 201c of the hook portion 201 of described the first elastic arm 20 extends outwardly beyond the straight line at described elastic arm 201 places.Thereby when snap gauge group 6 is inserted in card connector 100 completely, the end 201c of the hook portion 201 of the first elastic arm 20 extends to beyond the engagement grooves 64 in described snap gauge group 6.Like this, being convenient to snap gauge group 6 inserts in card connector smoothly.
Now, if user wants to take out snap gauge group 6, as shown in Fig. 8 a and 8b, he or she need to promote sliding bar 3 in inside along the direction as shown in arrow Z4 to card connector, by link member 14, snap gauge group 6 is released from card connector 100 along the direction shown in arrow Z5 thus.Along with sliding bar 3 moves inward, the protuberance 30 of sliding bar 3 moves to the inner side of the terminal part 20c of elastic arm 20,20c staggers with terminal part, thereby, it is large that spacing X between sliding bar 3 and elastic arm 20 becomes, the hook portion 20 of elastic arm 20 is easy to pushed outwards, thus easily release from hook portion 20 of snap gauge group 6, thus be easy to snap gauge group 6 to take out from card connector 100.Now, the withdrawal force F of snap gauge group 6 is mainly determined by the directed force F 1 between elastic arm 20 and snap gauge group 6.
Yet, if user directly extracts snap gauge group 6 due to misoperation, the situation occurring is as shown in Fig. 8 c and 8d, because sliding bar 3 can not move, now the gap X between elastic arm 20 and sliding bar 3 can not become large, snap gauge group 6 forces the end 201c of elastic arm 20 and the protuberance 30 of sliding bar 3 to contact in withdrawal process, the distortion of the hook portion 201 of elastic arm 20 is limited, therefore, snap gauge group 6 cannot be deviate from from the hook portion 201 of elastic arm 20, thereby snap gauge group 6 cannot be extracted from card connector.And now, the withdrawal force F1 ' of snap gauge group 6 is greater than F1 because the existence of the directed force F 2 between the end 201c of elastic arm 20 and the protuberance 30 of sliding bar 3 becomes.Thereby excessive withdrawal force can be pointed out user to have carried out unsuitable operation and be stopped continuing to extract snap gauge group 6, thereby has avoided damage card connector.
For the ease of the protuberance 30 on butt sliding bar 3, preferably, the end 201c of the hook portion 201 of described the first elastic arm 20 forms curved portions, and the protrusion direction of described curved portions is contrary with the projected direction of protuberance 30 on sliding bar 3.
As mentioned above, according to card connector of the present utility model, owing to being provided with jut on sliding bar, and the elastic arm on housing is arranged so that in snap gauge group and inserts under the state of card connector, jut on sliding bar is relative with the end of the hook portion of elastic wall on housing, therefore, and when product is worked or is fallen under vibration environment, can prevent that snap gauge group is unexpected deviates from from card connector, thereby has improved the reliability of product.In addition, can prevent user error and extract snap gauge group, prevent from damaging card connector and snap gauge group or SIM card.
